Medicine Aboard A Whaler

I answered an ask about this some years back that was...a few paragraphs long and was before I learned that some people have the stamina and desire to read 3k+ word whaling essays from me. So if ye count yourself among them, here you go!

---

On August 21st, 1870 aboard the whaleship Sunbeam, two-time whaler Silliman Ives found himself ill with a condition “very akin to mumps, with the exception of the swelling”. It prevented him from opening his mouth, and he dreamed of the days when such an action was possible.

“I never really appreciated the luxury of a good gape before. When a fellow cannot open his mouth to any greater extent than the width of a lead pencil, gaping is not a success to say the least. And then anything in the way of a sneeze is entirely out of the question, unless you are prepared to part company with the top of your head at very short notice. A ship is a hard place to be unwell in. So long as one is in good health you can get along nicely. But if you are sick the only place where you can find sympathy is in the dictionary. And then too the remedies at hand are limited in number and obsolete in use. Your medicine chest is filled with medicines in use a hundred years ago, but which modern pharmacy has dispensed with to a very great extent. Calomel and castor oil and such like delectable doses. There is no question about it. A whale ship ought to have a surgeon, and the law should oblige such vessels to carry them. When I get into Congress I shall introduce a “Bill” to that effect.”

As Mr. Ives noted, American whaleships went without doctors aboard even when the work was rife with injury and illness, and often quite far from access to any kind of care ashore. On British whalers it was required by law for a surgeon to be signed on for the voyage—Sir Arthur Conan Doyle was one on a voyage bound for the Arctic and apparently fell in the water so many times that the crew called him the 'Great Northern Diver'. However on American whalers—which dominated the industry—a doctor was seen by the agents as an unnecessary expense. There was the captain, the carpenter, and folks who could mend sails. Together, that makes one whole doctor! Right?

Read on, to see how they fared.

Joan Druett, in her book Rough Medicine highlighted some really fascinating things that came as a result of this, ranging from men who had scars that healed in a herringbone pattern because they were mended like canvas, to this wild tale about an amputation performed between a captain and mate at gunpoint:

“Another stirring tale told is of a Captain Coffin, who was hurt so badly in a whaling accident that it was obvious his leg would have to go. Being the master, the medic, and the patient all at once, he knew the situation was complicated, but he was more than equal to the task. He sent for his pistol and a knife, saying to his mate, “Now, sir, you gotta lop off this here leg, and if you flinch—well, sir, you get shot in the head.” Then he sat as steady as a rock while the mate went at it with the knife, holding the pistol unwaveringly until the operation was completed. No sooner was the stump wrapped up and the leg cast overboard than both men fainted.”

It was the captain's responsibility to provide medical treatment. Often without training himself, he was simply given a medicine chest full of numbered tinctures for various treatments. Those tinctures were a mix of chemical and herbal compounds, some which are still used holistically today and some that you.....absolutely want nowhere near your body. Epsom salts as a laxative, laudanum for painkiller, St John's wort for bruises and burns, mercury for syphilis, rosemary as an antiseptic, lead acetate as an anti-inflammatory, arrowroot for dysentery, henbane for insomnia, and on it goes from the innocuous to the dangerous.

John B King was a rare doctor aboard a whaleship, sailing on the Aurora out of Nantucket in 1837. He wasn’t hired as a doctor though; for reasons unknown he initially obscured his identity and joined simply as a foremasthand until his skills were revealed and he became the ship’s doctor. On that voyage he kept a book of the medicines he used.

John King’s medicine list, from the collections of the Nantucket Historical Association.

In addition to dosing medicine, the captain would also be responsible for setting broken bones, stitching wounds, and amputations. Benjamin Boodry, who had been whaling since the age of 13 and by 1856 was captain of the Fanny described instances in which he had to tend to his crew.

“At 2 o clock a cask of watter rooled away in the Bluber room and one John Haggerty tryed to stop it and got his leg broke just above the Nee there was another chance to show my surgical skill set it splinted it and bandaged it.” “McKee fel from the Main Topsail yard on deck bled him in both arms he came to some broke his arm and leg and badly bruised”.

Fortunately for McKee, his accident happened off the coast of Faial. The captain sent for a doctor ashore to examine him. He was advised to leave McKee in the Azores where he could receive more proper rest and treatment. But if land was a long way off, people had to make do the best they could.

Some captains had a better bedside manner than others. Where Silliman Ives felt terribly neglected in his illness, William Abbe of the Atkins Adams, 1859, had quite a different experience. He turned to the captain for help with a painful swelling on his hand that eventually grew so bad he was unable to use it.

“The captain was extremely tender in his treatment of my hand, pouring on laudanum to relieve the pain, lancing with caution and as tenderly as could he and using every means in his power to make me comfortable—washing my hand thrice a day with warm water and cutting away dead skin, pressing out matter in a manner that gained my affection + respect. Mrs. Wilson sent me preserved meats, pickled oysters, cake, buttered bread and seconded her husband in all his care. I felt a great deal of respect for both these kind people + shall repay it when I can […] The Cap treated us all with a care + skill that surprised me — I supposed that we should be left to take care of ourselves—the case in many ships, but we were not only cared for but allowed to stay below until we thought fit to return to duty.”

Mrs. Wilson--the captain’s wife--stepping up to help was not so unusual. Often whaling wives also found themselves taking on the role of doctor. All throughout July 1846, Mary Brewster was busy tending to the ailments of the crew aboard the Tiger.

“The last part of the day I have spent in making doses for the sick, in dressing some hands and feet, 5 sick and I am sent to for all the medicin. I am willing to do what can be done for any one particularly if sick for in whaling season a whaleship is a hard place for comfort for well ones and much more sick men.”

She reported that all her patients recovered, with the exception of a young man with a liver complaint beyond her immediate treatment.

Other times, other members of the crew served as de facto doctors as well. One such man was veteran whaler John Martin aboard the Lucy Ann 1842. In addition to being a skilled watercolorist, he also had a knack for bloodletting and tooth pulling. Often he made note of his ministrations in his journal:

“Blistered Frank on the side for his pleurisy & the steward on the neck for the sore throat” “Cupped the steward on the back of his neck with wine glasses and lanced with razor for want of proper instruments, which gave him almost instant relief” “Pulled a large jaw tooth for one of the crew. I lanced the gum with a penknife & set him spouting thick blood, & at the second wrench of the iron turned it up.” [Very cheeky language he’s using here, the same sort of talk one uses when hunting whales] “The loose whale struck Mr. Dean on the lower jaw & broke it, & knocked out 2 of his lower teeth, & he was taken on board [...] Sat up with Mr. Dean last night [...] Bled Mr. Dean [...] Drew 3 teeth from Mr. Deans broken jaw.” “Bled Antone. Since the death of Manuel, Antone has been on the sick list with swelled testicles and pain in his back. Poor fellow, he is very much frightened & thinks he is going to follow Manuel. He occupies the same bunk. When I bled him, he was so frightened that the perspiration stood on him in large drops, & groaned like a person dying.” “Blistered and glystered [clystered, i.e. gave an enema] Antone.”

One of John Martin’s watercolors from his journal. NBWM.

Blistering, bleeding, and emetics were among the most common treatments for all that ailed a man aboard. John King included his recipe for creating a blistering plaster and its uses:

“Blisters are serviceable in affections of the chest attended with much pain and difficulty of breathing. Bleeding or purging is proper previous to the application. Severe and long-continued headaches are relieved by a blister to the back of the neck. In all cases before applying a blister, the part should be washed with warm vinegar and wiped dry. The plaster should be spread as thick as a wafer on soft leather. When laid aside it soon becomes mouldy in the dampness of a ship, but if rubbed over with a knife the same one will draw two or three times. When very old it loses its strength. From eight to twelve hours is the time usually required for drawing a blister. Then remove it and dress with basilicon or simple ointment”

—

Other ailments were met with more specific treatments. It was not uncommon to see logbooks noting several men laid low on account of ‘the venereal’. William Chappell, a cooper and boatsteerer aboard the Saratoga in the early 1850s commented on the frequency the mate found himself off duty following liberty ashore. 

“Our mate is off duty again with that disgracefull disease and as near as I can find out it threatens destruction to a small but very usefull member of the body  I am sorry for him but he is old enough to know better than to play with every body that looks pretty and bewitching”

“Flaxseed tea is very serviceable in clap”, wrote John King in his journal, as well as white vitriol “sometimes used as an injection in protracted cases of clap.” For syphilis, the common treatments were more severe. King writes,

“No 25. Mercurial Ointment This is frequently used in venereal cases for bringing the system under the influence of mercury. The bulk of a small nutmeg is rubbed on the inside of the thighs morning and evening until the gums are slightly sore. It is a good application to chancres when mixed with twice the quantity of lard, and renewed twice a day.”

Mercury compounds could also be injected into the urethra. There were doctors who spoke out about the use of mercury in treating syphilis contemporary to when use was at its height. One 1853 advertisement in the New Bedford newspaper the Whaleman’s Shipping List reads,

“Important to the Afflicted CONFIDENTIAL TREATMENT in Medicine and Surgery may be had of Dr. TOMPKINS at his office in rear of the Apothecary’s Shop, No 58 Middle, corner of North Second St  Dr. TOMPKINS gives particular attention to the treatment and cure of private diseases. All those who have been taking medicines of their own prescribing, or from certain inexperienced or self-styled physicians, for a long time without benefit, are respectfully invited to call on Dr Tompkins, who is a regularly educated Physician of twenty years experience, and is competent to treat diseases of all kinds, and in every stage and form. Dr. T. warns the public against the abuse of mercurials; he is convinced by long experience, that most of the chronic affections, generally supposed to be the relics of diseases, are merely the effects of a long continued course of mercury. Recent affections cured in a very short time, without a grain of mercury”

Even with such objections, mercury compounds still were the standard and did more to sicken their patients than cure them. While whalers were often listed as being off duty due to venereal disease, there was less comment about whether or not they were given anything to attempt to alleviate it compared to other conditions.

“Our mate limping about again—had another furious attact of the venereal He is a used up man I fear,” Mr. Chappell wrote. Ultimately the mate was in a poor enough condition that he left the voyage at the next provision stop they made.

—

Scurvy was another common affliction. Given that whaleships spent extended time at sea and were loathe to waste too much time with anchoring somewhere, fresh food ran low quite often. When whaling in the Atlantic and South Pacific whalers usually fared okay, as there were a fair number of provision stops in locations that had fresh fruits and vegetables readily available for trade. It was on said provision stops that whalers could also, as said by Samuel Wood of the Bowditch, 1849, take a walk to 'knock the scurvey from their bones’. In seasons that took place up north however, in the North Pacific, Sea of Okhotsk (Kamchatka Sea), Bering Strait, and eventually up into the Arctic, scurvy was extremely prevalent. The fresh food depleted, the ice was always a threat, and unlike other regions there weren't many accessible places to resupply with large amounts of foods that could ward off scurvy. It's in reading journals during these periods that I find the most complaints of scurvy. And sometimes, the more successful the voyage was, the sicker the men would get because they'd spend more time up there rather than giving up and returning south. The US Consul in Hawaii complained of this in the 1840s, saying:

"Whaleships were much more successful in taking oil on the North West during the last summer and fall than for three or four seasons previous and most of the vessels remained on the fishing grounds much longer than usual, the consequence of which was that many of the crews were severely afflicted with scurvy, some died after reaching port and before they could be landed, while others were carried to the hospital on litters, being too feeble to walk."

There were endless attempts to ward it off. John Martin wrote of men "In the evening, dancing cotillions and jumping the rope to keep off the scurvey". It didn't seem to do much. Within two weeks:

"One man on the sick list, supposed to be caused by his being so long at sea. All hands are complaining of soreness throughout their bodies. If we do not get on shore soon, we may expect to have half the crew down with the scurvey at least. We have no vegetables on board, and are going into King Georges Sound, New Holland [southwest tip of Australia], a place where we can scarcely get anything to recruit with."

His captain allowed the crew unlimited vinegar and free access to the potato pen. The vinegar, a mistaken remedy due to its acidity, wouldn't have helped much. Potatoes are an excellent source of vitamin C, more so when they're raw, but they were rather intolerable to eat in such a way.

William Chappell spoke of a similar struggle with potatoes, and the grim humor the lads maintained to choke them down:

“Three of our men are off duty with the scurvy which makes its appearance in the knees and feet All hands are called aft every morning to get 2 or 3 potatoes apies which they are required to eat raw in the preasance of the officers for fear they may throw them overboard as many require presing invitation to partake of the dainties They have however a considerable sport over them Call them Kodiak Peaches”\

Aside from the crunch of Kodiak Peaches, Dr. King had his own remedy for scurvy as well:

“13. Salts of Lemon This is good in scurvy when fresh fruit and vegetables can not be obtained. A teaspoonful dissolved in half a pint of water will form an acid nearly the strength of lime juice. It may be mixed with water and taken freely, sweetened or not. [it makes a good substitute for lemonade, in fever, to allay thirst in fever] Water made slightly acidic with it is a good substitute for lemonade to allay thirst in fever."

The Sailor’s Hospital in Lahaina, Maui, constructed in the early 1830s.

For all the varying attempts to hold off sickness, it took root among crews nearly every voyage. J.E. Haviland of the Baltic, in the early 1850s spent the last few dozen pages of his journal in a state of declining health and low spirits.

“My side and breast pain me nearly all times I have not been on deck since I came below. The Captain and Mr Stivers are both very kind and come down to see me as often as once a day and sometimes two or 3 times. I am taking medicine but it does not seem to do much good but I think I am better than I was at first. Dear mother how I do wish I could see you once more. I get so homesick and I know I am peevish and cross. Some days I cannot get out of my bunk at all. I blame the captain (wrongfully I know) thinking he does not give me the right medicine but it is a very bad place to be sick at sea.”

He suspected it was due to the harsh conditions of whaling up North, but also held a fear within him that it might be something more serious that couldn’t be remedied simply by warmer climes.

“Dear mother, I shall be obliged to leave the ship when we arive at the Sanwich Islands for I do not think I could live doing another season in the cold Norwest. My cough seems to increase and the pain in my side gets no better I am getting weaker each day and am getting very thin in flesh. I have said nothing as yet to the old man about my leaving at the island as I do not know as he will be willing that I should; but I intend going to a doctor and in all probability will tell the old man I am not fit to go North in the ship […] I would like very much to be in the states now for I am afraid this will turn out to be the Consumption that I have. I think if I could have good medical advice I might get rid of it before it got seated upon my lungs. I am afraid it will be a long before I shall see my native land again.”

Ultimately Haviland is discharged from the ship because of his sickness and is left at the Sailor’s Hospital in Lahaina. His stay seems to do him well. His last entry reads:

“I have been here now going on two months and am entirely free from my cough and think I feel as well as ever again. It is intensely hot and I am heartily sick of the place and sincerely wish I could get away but I do not expect any chance before next fall.”

Unfortunately from here he completely drops off the record, so it’s unknown if he ever made it back home. Like so many of these men, he slips through the cracks of documented history. It’s only through their journals, preserved by chance, that their voices and challenges and feelings are known. Often a whaling voyage marked at least one death due to disease or injury. But many also recovered, sometimes rather miraculously given the circumstances and extent of their ailments. In the face of the conditions of a whaler and the limitations of care both in terms of resources and medical understandings at the time, I’m always surprised that there wasn’t more death. People did what they could, with the knowledge they had.

But as so many people expressed while laid up in their bunks: it’s a hard time to be sick at sea.

Page 187 was lists of the procedure so I had to go back a page and a half 🫰psychiatry textbook sounds interesting 👀

Unit V: Biological Solutions

This was my introduction when I was in my biotech program… ah the memories.

Tris buffers change pH significantly with changes in temperature. The pH of a Tris buffer will decrease approximately 0.028 pH units with every 1 deg C increase in temperature.

The pH of buffers changes with dilution. The pH of Tris buffer decreases about 0.1 pH units for every tenfold dilution. Generally the change in pH of Tris when it is diluted is not a problem, so Tris buffers are often mixed as concentrated stock solutions. If this dilution effect is a problem, then the use of stock solutions should be avoided.

Tris buffers require a compatible electrode for accurate pH determination. Some manufacturers recommend using a calomel (mercury) reference electrode rather than a silver/silver chloride electrode.

We will use HCl to bring Tris to the right pH, but other acids can also be used specifically for applications. For example, boric acid, citric acid, and acetic acid can be used to prepare Tris-borate, Tris-citrate, and Tris-acetate buffers, respectively.

Me; I understand very little of that but I do understand pH, buffers, solutions, electrode, acid.

But very cool! If ya give me a minute I can go grab my book and ask ya a number to choose from.

Records I Am Glad to Have Found in 2023: Part 2

"Part" may be the wrong way to express this as a series but it's too late now.

Superdragons – "Super Dragon" promo 12" (Mercury, 1976)

There's a shop north of Chicago that's the kind of place where the immediate charms of digging for wild records are often rewarded. I have a regularly scheduled appointment out near this shop, which gives me an excuse to stop in every few months and see what's changed. Every time I go, I seem to clean out a section that doesn't immediately get replenished, but in typical crypt-style record store fashion, there's always something more to find.

In recent years, that section has been their 12" singles. If this is the thing you're looking for, record shops with heavy inventory truly cannot be beat. You won't typically have much competition getting down on the floor and looking under the browsers or whatever dusty, low-traffic area this format is typically relegated to.

Which is to say, on a previous visit I found a promo-only Bohannon single and was regaled with a story about The Gilbert Kong collection. Kong was a Mercury Records mastering engineer who at some point dipped out to work on his own, but I'm told he kept his contacts and worked with the label steadily throughout the '70s. His craft is most readily apparent on a series of 12" promo singles, pressed for radio and disco use, which were generally not for sale. A relative who had inherited his collection wound up selling it to this store, they found an acetate of the first Rush album out of it (which they donated to a Rush museum, apparently, after being rebuffed when presenting UMG with the chance to use it for a reissue), and most of the 12"s quietly went out for sale.

You can identify these records by their monochromatic, plain sleeve art, and a catalog prefix of MK. In every instance I've come across, the record is mastered LOUD, with incredible fidelity and bass response. Kong had no compunction about spreading three minutes of music across an entire side of a 12", and the results are about as deep and rewarding as you'd expect from an audio standpoint. Whether the music – typically disco records pushed by the PolyGram fam, top 40 hopefuls, and sampler albums – is your bag, that's another thing. A frequent target of bootlegging, these promos weren't pressed in significant quantities; the appeal of DJing with a really full, loud copy of, say, the Osmonds "I, I, I", as opposed to the squashed fidelity of the same song on the LP, cannot be overstated. Second-market pricing on these varies wildly, from a few bucks to a few hundred.

I grabbed a bunch of these releases on my last visit, sound unheard. The bare, red print of "Super Dragon DISCO VERSION" by Superdragons did its best to blend in, but the anonymity of it all, a heady year of release, and a production credit for Bunny Sigler held promise.

Did it ever! Clearly a product of Philly's finest studio musicians, "Super Dragon" looks to glom as many popular song ideas together as a single track could hold, with panicked, immediate strings, parping brass, rolling rhythms and virtually nothing at all to say. "Draaa-gon! Draaa-gon! Super dragon, super dragon." That's all you get! You also get notions of Bobby Womack's "Across 110th Street," Rhythm Heritage's "Theme from S.W.A.T.," and Steve Miller's "Fly Like an Eagle," three tracks I wouldn't have thought should go together until now. "Super Dragon" is a full-tilt disco hustler with big main title soundtrack energy, and I wasn't surprised to find out it was used for just that (an excerpt turns up in a Bruce Le movie, 1978's Bruce and Shaolin Kung Fu).

Superdragons left it all out on the field after this one; the B-side contains the same song, in case you wear it out. Apart from a customary pressing as a 45 (with Part 1 and Part 2 indicators), this was it. This 12" presents a unique disco mix with no side break, and at 5+ minutes runtime gives you everything you came for and a little more.

Crown Heights Affair – "Say a Prayer for Two" b/w "Galaxy of Love / I'm Gonna Love You Forever" promo 12" (De-Lite, 1978)

Probably don't need to say much about this known disco slammer, presented here with a little more of an intro. The bass response on this one is fucking insane, and if this isn't getting your floor moving/potted plants dancing off the shelf, you might be doing it wrong. A high point in these Mercury promo offerings, and my favorite song from this group.

City Boy – "5.7.0.5." promo 12" (Mercury, 1978)

Loved this song from the first time I heard it. City Boy's biggest hit, this has some real right place/right time energy, the vaguely new wave screamer ELO never really had in 'em (at least not in '78). Grooves on this one are cut so wide you can almost sightread them from across the room. I was hoping one of these would be in with the rest at this shop.

Essence Project ♡ Rules and Additional Information

This essence is the follow-up location to the Emerald Masquerade essence! This one takes place inside of a famous in-universe laboratory, however.

Similar to its sister essence, there will be mentions and discussions of death and murder, and its main s tier (Ammonia) will be chosen via the spin of a wheel! In addition, deaths will be chosen through the wheel, however, two characters will be excluded from being selected as the killer. Who those two characters are? You'll have to find out.

Due to the age range of the essence, every character here will be over 18, and most of them are canonically over 21. Therefore, if possible, I'd like all muses to be at least 18 years old, or, an adult.

Antherea Polyphemus

https://entnemdept.ufl.edu/creatures/MISC/MOTHS/polyphemus_moth.htm

The polyphemus moth, Antheraea polyphemus, is one of our largest and most beautiful silk moths. It is named after Polyphemus, the giant cyclops from Greek mythology who had a single large, round, eye in the middle of his forehead. The name is because of the large eyespots in the middle of the hind wings. 

The family name Saturniidae is based on the eyespots of some members of the family that contain concentric rings reminiscent of the planet Saturn. Because of their ease of rearing and large size, polyphemus moths are often reared by amateur enthusiasts and also have been used for numerous physiological studies - particularly for studies on molecular mechanisms of sex pheromone action.

Polyphemus moths are our most widely distributed large silk moths. They are found from southern Canada down into Mexico and in all of the lower 48 states except for Arizona and Nevada 

First instar larva of polyphemus moth, Antheraea polyphemus 

Older instars are yellow-green, and the setae become relatively less prominent with each molt. The translucent yellowish-green to green, full-grown (fifth instar) caterpillars are 60 to 75 mm in length 

Fifth instar larva of polyphemus moth, Antheraea polyphemus

Cocoon and Pupa: The single-layered cocoon is thicker and more elliptical than the cocoon of the luna moth

Adult eclosion (emergence from pupa) typically occurs in the afternoon with males usually beginning emergence several days before females from the same brood. Afternoon emergence allows time for expansion and drying of the wings prior to the evening flight period. Also, during the first day after emergence, the moth voids the liquid meconium which is composed of the breakdown waste products of the old larval tissues. 

The adults are strongly attracted to light - particularly UV wavelengths. There has been some concern that light pollution from man-made sources (particularly mercury vapor street lights) may deter silk moths from mating and have a negative impact on their populations in urban areas (Worth and Muller 1979). Fortunately, mercury vapor lamps are not used as commonly as they once were for street lights.

Females release a sex-attractant pheromone and may attract males from a distance beginning late evening of the day of emergence. The sex pheromone has been characterized as a 90:10 mixture, respectively, of trans-6,cis-11-hexadecadienyl acetate and trans-6,cis-11-hexadecadienal (Kochansky et al. 1975). While males are attracted all night long, maximal attractiveness is during the last two hours before sunrise (Kochansky et al. 1977). Mating pairs remain coupled throughout the day and separate at dusk. Either caged or tethered females can be used to attract wild males. Worth (1980) has designed a tether for this purpose that prevents the tethered moth from escaping or twisting the tethering line around its body.

Females begin laying eggs the evening after mating and continue for several nights. Eggs are laid singly or in groups of two or three on leaves of the host plant (Opler et al. 2012 ). In captivity, they will lay their eggs on any substrate. Adults have vestigial mouthparts and do not feed. Therefore, they are short-lived. 

Caterpillars are solitary and develop through five instars. Immediately after hatching, caterpillars eat their egg shells (Opler et al. 2012 ). Older instars eat whole leaves and then sever the petioles to drop them to the ground (Tuskes et al. 1996) - possibly to obscure their presence from predators The presence of large larvae on branches overhead may often be detected by the presence of frass (caterpillar droppings) on pavement of driveways or parking lots.

Scientists Find Origin-of-Life Molecule in Space for First Time

— By Jess Thomson | August 8, 2023

NASA image of the Tarantula Nebula star-forming region taken by Webb’s Near-Infrared Camera. A molecular cloud in interstellar space has been found to contain carbonic acid for the first time. NASA, ESA, CSA, AND STSCI

molecule common to Earth and usually associated with life has been detected in the depths of space by scientists.

Carbonic acid (HOCOOH), which you may know as the chemical that makes your soda fizzy, was discovered lurking near the center of our galaxy in a galactic center molecular cloud named G+0.693-0.027, a study published in The Astrophysical Journal revealed.

This marks the third time that carboxylic acids—this class of chemicals, often thought to be some of the building blocks of life—have been detected in space, after acetic acid and formic, and the first time that an interstellar molecule has been found to contain three or more oxygen atoms.

"Our observations have allowed us to know that carbonic acid, which until now had remained invisible to our eyes, is relatively abundant in space, which makes it an essential piece to understand the interstellar chemistry of carbon and oxygen, two of the fundamental chemical elements in any prebiotic process," Víctor M. Rivilla, a researcher at the Spanish Center for Astrobiology and co-author of the study, told German broadcaster Deutsche Welle (DW).

"This result confirms that the path we have chosen is the right one to search for, and detect more molecules that we suspect were key to the appearance of life on our planet," he concluded.

Carboxylic acids are a type of organic compound characterized by a carbon (C) atom doubly bonded to an oxygen (O) atom and singly bonded to a hydroxyl group (―OH). Carbonic acid in particular is formed when CO2 is dissolved in water, meaning that it is present in increased concentrations in our seas due to CO2 in the atmosphere.

Many theories as to how life on Earth evolved suggest that primitive life may have emerged from a primordial soup of chemicals when our planet was very young. Some have suggested that these chemicals, including carboxylic acids, may have arrived on Earth from space, traveling via comets and meteorites to the forming planet.

Carbonic acid has been previously detected on other astronomical bodies, including the icy moons of Jupiter, in some meteorites and comets, and even on Mars and Mercury, but until now, has not been seen in interstellar space.

The authors explained that the discovery of these more complex molecules in the interstellar medium may reveal clues about the origins of our planet and the life upon it.

"The presence of prebiotic COMs within extraterrestrial material thus firmly suggests the existence of carboxylic acids of increasing complexity in the ISM (interstellar medium), including amino acid–related species. Within this context, considerable efforts have been devoted to hunting for other acids, such as propenoic or acrylic acid, propanoic acid, cyanoacetic acid, glycolic acid, hydantoic acid, and glycine, whose identification in the [interstellar medium] remains elusive."

Toxic Heavy Metals and Chelation Therapy

Comprehensive Treatment Approaches for Heavy Metal Toxicity at Restoration Healthcare

Once a diagnosis is certain, numerous treatments will be prescribed. At Restoration Healthcare, our doctors use an integrative approach to treating heavy metal toxicity, considering personal health history and existing condition(s). A physician will do a thorough workup to include specific testing of the neurologic systems, which is the most sensitive system affected by heavy metal

toxicity. We work closely with each patient to develop a personalized approach that addresses diet, exercise, stress management, and nutritional supplements.

Chelation intravenous therapy is a primary treatment method to aid the body in ridding it of toxins. Chelation therapy uses compounds that bind with heavy metals and allows the body to eliminate toxins. The term chelation means to bond. The most effective chelation therapies are delivered through the bloodstream in an intravenous IV Therapy drip.

The most common chelating agents include dimercaprol, DMSA (Dimercaptosuccinic acid), and CaEDTA (calcium ethylenediamine tetra-acetic acid). At Restoration Healthcare, we prefer CaEDTA because heavier metals, such as lead and mercury, have a greater affinity for EDTA and form stronger bonds. Our trained IV therapists administer a prescribed dose of CaEDTA, which attaches to heavy metal toxins and certain minerals and forms chemical compounds called chelates. The chelates travel through the blood to the kidneys, filtered and excreted in the urine.

If you suspect you have been exposed to heavy metal toxins affecting your health, you must get medical help. You may be tempted to use a home detox plan, but this severe health issue needs medical supervision and guidance. Whether your symptoms are related to heavy metal toxicity or something else entirely, Restoration Healthcare will investigate and provide you with an integrative healthcare plan to help restore your body to health.

Earliest Types of Camera

The history of photography dates back to the early days of human civilization, with various devices used to capture images of the world around us. This article explores some of the earliest types of camera and their impact on the development of photography.

Camera Obscura

The camera obscura, a device used to project images of the outside world onto a flat surface, was one of the earliest forms of camera. It was used by artists as a drawing aid and by scientists as a tool for observing solar eclipses and other phenomena.

The basic principle of the camera obscura was known to the ancient Greeks and Romans, but it wasn't until the Renaissance that it became a popular tool for artists. By the 18th century, portable camera obscuras had been developed, allowing travelers to capture images of the world around them.

Daguerreotype

In 1839, French artist Louis-Jacques-Mandé Daguerre announced the invention of the daguerreotype, a process for capturing photographic images on a silver-coated copper plate. The daguerreotype was the first practical method for producing photographic images and revolutionized the field of photography.

The process involved exposing a sensitized plate to light, developing it with mercury vapor, and fixing the image with a solution of common salt. The resulting images were sharp and detailed, but the process was complex and time-consuming.

Calotype

In 1841, Englishman William Henry Fox Talbot introduced the calotype, a process for producing photographic images on paper coated with a silver salt solution. The calotype was the first photographic process to use a negative, allowing multiple prints to be made from a single image.

The calotype process involved exposing a sensitized paper negative to light, developing it with a solution of gallic acid, and fixing the image with a solution of sodium thiosulfate. The resulting images had a softer, more naturalistic look than daguerreotypes and were easier to produce.

Wet Plate Collodion

In 1851, British photographer Frederick Scott Archer invented the wet plate collodion process, which used a glass plate coated with a solution of collodion and light-sensitive silver salts. The wet plate collodion process was faster and more versatile than the daguerreotype and calotype processes, and became the dominant photographic method of the mid-19th century.

The wet plate collodion process involved coating a glass plate with collodion, sensitizing it with a silver nitrate solution, exposing it to light, and developing it with a solution of iron sulfate and acetic acid. The resulting images were sharp and detailed, and could be reproduced in large quantities.

Conclusion

The earliest types of camera were rudimentary devices that relied on simple principles of optics and chemistry to capture images of the world around us. From the camera obscura to the daguerreotype, calotype, and wet plate collodion processes, each new development brought new possibilities and expanded the boundaries of what was possible with photography.

Today, we take for granted the ease with which we can capture and share images with our smartphones and digital cameras. But the legacy of these early photographic pioneers lives on, inspiring and informing the work of photographers around the world.

Industry of pharmaceuticals

The National Exit Test (NEXT) is a standard stepping stone to advanced medical education. National exit exam for MBBS will be replacing NEET PG, and FMGE exams for MD, MS, and MDS courses.

 The pharmaceutical industry, the study, creation, and production of pharmaceuticals by both public and commercial entities.

 After thousands of years of intuition and trial and error led people to believe that plants, animals, and minerals had therapeutic properties, the modern era of the pharmaceutical industry—characterized by compound isolation and purification, chemical synthesis, and computer-aided drug design—is generally regarded as having started in the 19th century. The understanding of fundamental drug-discovery processes improved with the integration of research in the 20th century in disciplines like physiology and chemistry. The pharmaceutical sector is currently faced with obstacles such as finding new therapeutic targets, obtaining regulatory approval from government bodies, and improving drug research and development methods. The global control and eradication of disease depend critically on the pharmaceutical industry's ongoing development and advancement.

 The process of drug discovery and development throughout history, the process of drug development in the contemporary pharmaceutical industry, and the steps taken to ensure the creation of safe pharmaceuticals are all thoroughly explained in the parts that follow. Visit drug for more details about drugs. See medicine for a thorough explanation of medical practise and the function of drug research in the healthcare sector.

 History

 where drugs first came from

 ancient civilizations' medicines

 The early Chinese, Hindu, and Mediterranean civilizations are responsible for the earliest accounts of therapeutic concoctions made from plants, animals, or minerals. Chang shan, a substance derived from the plant species Dichroa febrifuga, was described as having antifever properties in a herbal compendium that is thought to have been written in the 28th century BC by the legendary emperor Shennong. It has since been discovered that this substance also contains antimalarial alkaloids (alkaline organic chemicals containing nitrogen). In the second century BC, workers at the Alexandria School of Alchemy in Egypt created numerous reasonably pure inorganic compounds, such as lead carbonate, arsenic, and mercury. Verdigris (basic cupric acetate) and cupric sulphate were recommended as drugs, according to the first-century AD work De materia medica by the Greek physician Pedanius Dioscorides. Although attempts were made to employ several of the mineral formulations as medications, the majority turned out to be too poisonous for this application.

 There are still several plant-based medicines in use today that the ancients used. Senna pods, castor oil, and peppermint were used by the Egyptians to alleviate indigestion and treat constipation, respectively. Different plants that contained cardiac stimulants (compounds similar to digitalis) were used to cure a variety of illnesses. Ma huang, a herb containing ephedrine, was used by ancient Chinese physicians for a number of conditions. Ephedrine is now a common ingredient in numerous pharmaceutical products used to treat cold and allergy symptoms. Opium and squill were among the medications at the Greek physician Galen's (c. 130–c. 200 AD) pharmaceutical store (pharmacy). While squill was once utilised as a heart stimulant, it is now more commonly used as rat poison. Today, derivatives of opium alkaloids are frequently used for pain management. Galen made numerous significant conceptual contributions to modern medicine, despite the fact that many of the therapeutic substances he utilised are no longer in use. He was among the first practitioners, for instance, to insist on drug purity. He also understood how crucial it was to employ the proper variety and age of botanical specimens while creating medications.

The exam, which is expected to replace NEET PG, will serve as a common qualifying final year MBBS exam in addition to being a screening NEXT exam for foreign medical graduates (FMGs) who want to practice in India. Next will be conducted in two separate exams defined as 'Steps'.

Navigating the World of Solvent Waste Management: A Guide to Recycling and Disposal

Companies in today’s market must be as competitive and efficient as possible. Most businesses must find ways to cut any unnecessary operating costs while also adhering to stringent waste management regulations. If your activity involves the use of hazardous solvents, you may need to implement an effective solvent waste management plan. What could be better than installing in-house solvent recycling equipment?

Waste Solvents that You Can Recycle Using this System: 

Non-Halogenated Solvents: This is the most common type of general waste and includes solvents such as methanol, acetone, ethanol, ether, ethyl acetate, hexanes, and toluene.

Halogenated Solvents: These include halogenated solvents such as dichloromethane and chloroform, either in total or as a mixture (methylene chloride)

Heavy Metals Solvents: This includes any solvent waste that contains heavy metals such as arsenic, cadmium, barium, chromium, lead, selenium, mercury, and silver.

Paint Solvent and Residue: This waste is the result of using oil-based paints and thinners, which include oil-based paint residue.

It is crucial to abide by a few key guidelines when working with solvent recycling equipment or any other hazardous liquid waste stream. Reactive materials, for instance, should never be there in a single waste container.

It is not advisable to add acids, alkalis, oxidizing, peroxide, and reducing agents to various solvent waste streams. They need to be properly labeled as hazardous chemicals, kept apart from other waste, and handled accordingly.

Repurposing Solvents and Liquid Waste

Recycling should always be the first option to consider when possible. For businesses that generate large amounts of hazardous liquid waste, disposal can be an expensive process.

Apart from the obvious environmental benefits, implementing an effective recycling policy can provide a more cost-effective solution for the business. Managing hazardous liquid waste poses a risk in the workplace that must be properly assessed and managed.

Additionally, storing hazardous waste containers ready for pickup can take up valuable space. Therefore, having on-site solvent recycling equipment is quite useful. 

The ability to recycle your solvent waste can significantly reduce your purchase costs, as most equipment can recycle up to 95% of your liquid waste. You may also be able to avoid nearly all disposal costs if, after recycling, you end up with pure re-usable solvent that is no longer hazardous and can be disposed of through your municipal system.

Solvent recycling is an excellent option for businesses that manufacture byproducts such as printing and ink, coatings and paint, metal finishing, and automotive painting. Recycling systems come in a variety of configurations, ranging from batch loads to fully automated processes.

Guess what? you can dispose of it through your municipal system.

Solvent recycling equipment is an excellent option for businesses that manufacture byproducts such as printing and ink, coatings and paint, metal finishing, and automotive painting. Recycling systems come in a variety of configurations, ranging from batch loads to fully automated processes. Make sure you choose the right one based on your type of industry and business operations. 

Still Not Saving Money on Solvent Recycling?

Don’t worry; you can be a little stubborn at first. If you’re not already saving money with solvent recycling, you’re probably still having to store, dispose of, and transport a lot of hazardous waste.

While solvent recycling will not reclaim all of your spent solvents, it can recycle up to 90% of them, depending on the waste type. On other hand, if you are still transporting your hazardous waste, it can cost a pretty penny.

Solvent Recycling Procedures

Tolling is one method that cleans the solvent to a predetermined specification and then returns it to the business for reuse. This is fairly common, as many businesses use it due to its ease of use and effectiveness in determining which solvents can be used in the future.

Another method for recycling solvents is converting solvents into products for reuse, specifically for commercial product manufacturing. This method also has a lot of advantages because it helps to reduce overall waste volumes.

Another option is reclamation, in which, similar to tolling, solvents are cleaned to a company’s specifications but then delivered to third parties.

Is It Profitable to Recycle Industrial Solvents?

Solvent recycling not only helps to preserve the environment, but it also helps to reduce the additional cost of purchasing new solvents. Recycling has reduced the need to purchase new solvents because existing ones can be recycled. Chemical laboratories, auto body shops, paint shops, chemical industries, and paint contractors are all significant contributors.

However, it has not reduced the demand for solvents and has created numerous new opportunities in the solvent market.

Companies provide recycling technology, services, and recycled solvent to customers.

The other type offers solvent recycling machines for sale.

The third category provides both services and sells machines.

So, once you choose to use solvent recycling equipment you can actually make the most of it. 

You lose out on a lot of advantages if your company does not recycle solvents:

A Significant Return on Your Investment

Recycling Solvents not only helps businesses cut costs and waste, but it also helps them establish a solid reputation in the marketplace. It is the greatest advantage that any business can take advantage of. You don’t need to constantly buy new solvents; you can simply recycle the ones you already have and begin manufacturing.

Making Money 

Additionally, you can increase your income by recouping the cost of your recycling program by selling recyclable waste to other businesses as an alternative.

Recyclable materials are now a precious commodity. Metals, plastics, glass, and other materials gain in value as their price rises thanks to improvements in recycling technology. You only need to research local market prices and look for consumers willing to purchase recyclable goods.

Conclusion 

Using solvent recycling equipment is profitable for every industry, whether the profits are monetary or not. No matter how many solvents you recycle at once, if you make it a habit, you can increase your marketability and make financial savings.
