Do you know that a 3000-year-old honey was still edible? Does honey ever spoil?

Back to school finally!! +Photo dump of the food from the last weeks of summer break. +Roommate featured.

Our new dorm building is better than I expected, just waiting for maintenance to take off the wonky closet door.

22/25 Days of Productivity

Did Fermentation, Cori Cycle, Feeders Pathway and hopefully will learn about Fates of Pyruvate. Made a healthy and tasty breakfast today!

scifi au dave taates organic meat for the first time in his life when hes like 15. all hes known before that is cheap pan-species non-offensive printer meat that tastes kinda dull

Most people know of CBD's benefits at treating chronic pain and anxiety, but some studies have also shown that it helps limit microbial and fungal growth. A research team in Thailand wanted to discover if this quality could be harnessed to create an edible coating that could keep strawberries fresher, longer (spoiler: it can!).

Before they could test CBD's effects on food freshness, they needed to find a way to distribute the oil evenly in water. The method that they used involved creating nanoparticles consisting of a CBD molecule surrounded by an edible polymer that is commonly used in drug delivery, poly(D,L-lactide-co-glycolide). Surrounding the oil in this polymer allowed it to easily mix with the water instead of separating out to the surface. The most stable of these particles that were selected for the study contained about 20% CBD by weight. These were added in different concentrations to a solution of water and sodium alginate, which is a current antimicrobial coating for fruits.

Strawberries were dipped into the nanoparticle solution for two minutes, followed by a dip in another solution to solidify it into a thin gel layer. Then, they were left in an open container at fridge temperature for 15 days. The strawberries treated with the highest concentration of CBD nanoparticles performed the best on all levels- they maintained their dark red color, had increased antioxidant activity, and were protected from microbial growth. These results are preliminary, but they certainly suggest potential for CBD oil to be used to keep your food fresh!

my uni flatmates will leave a half-full can of open baked beans out on the side in the kitchen for two weeks and then turn to me and go omg!! you go home sooo often haha you’re like never here!! like yeah babe i know…you guys are cultivating new fungal ecosystems in our kitchen i need to return to civilisation and clean surfaces…

LET ME RECOMMEND YOU A BATH BOMB RECIPE! YOU CAN USE TO GAME THE DOPAMINE LEVER IN YOUR BRAIN!!!!! GIVE ME YOUR FAVORITE, GROSSEST, KINKIEST, NASTIEST, MOST DELICIOUS SMELL!!!!!!!! AND I WILL PERSONALLY MAKE YOU TGE MOST AuDHD/Gifted/MOGAI tumblr slime cooking baking kitchen recipe for it!

Make comic con smell good! Please! I’m begging!!!!!!!!

showering:

pros: you get to feel clean. you get non greasy hair, non oily feeling skin, it just in general makes you feel better, more energised, refreshed.

cons: there are so many steps. oh my god are there so many steps. before getting into the shower there are steps. during the shower there are steps. and once youve gotten out of the shower? guess what!!! more fucking steps!!!!!!!! UGHHHH

The somewhat abrupt change from local food sources to national and international ones, along with the chemicals added from mass manufacturing processes, warped people’s metabolic systems and gut biomes, keeping them alive longer than before this change, but at the cost of their intelligence, and awareness, along with their mental and physical health. The most humane thing to do would be to put them out of their misery, instead of corralling them into Faustian for profit prison-like systems.

Drinking water after eating spicy food might not be the best solution…🔥

New approach to monitoring freshwater quality can identify sources of pollution, and predict their effects - Technology Org

Analysing the diversity of organic compounds dissolved in freshwater provides a reliable measure of ecosystem health, say scientists.

According to scientists at the University of Cambridge and Trent University, Canada, the source of pollutants in rivers and freshwater lakes can now be identified using a comprehensive new water quality analysis.

Microparticles from car tyres, pesticides from farmers’ fields, and toxins from harmful algal blooms are just some of the organic chemicals that can be detected using the new approach, which also indicates the impact these chemicals are likely to have in a particular river or lake.

Importantly, the approach can also point to the origin of specific organic matter dissolved in the water, because it has a distinct composition depending on its source.

The approach uses a technique called high-resolution mass spectrometry to analyse water samples: within an hour this provides a comprehensive overview of all the organic molecules present.

Water quality is strongly determined by the diversity of organic matter dissolved in it – termed ‘chemodiversity.’ The scientists say that the thousands of different dissolved organic compounds can keep freshwater ecosystems healthy, or contribute to their decline, depending on the mixture present.

The paper is published today in the journal Science.

“Traditional approaches to monitoring water quality involve taking lots of different measurements with many devices, which takes a lot of time. Our technique is a very simple way to get a comprehensive overview of what’s going on in a particular river or lake,” said Jérémy Fonvielle, a researcher in the University of Cambridge’s Departments of Plant Sciences and Biochemistry, and co-author of the paper.

To understand what drives this chemodiversity, the team reviewed studies of dissolved organic matter in freshwater samples from rivers and lakes across Europe and northern Canada.

For example, water analysis of Lake Erie in Canada revealed high levels of phosphorus pollution. By looking at the composition of individual molecules in the water sample, researchers identified agricultural activities as the source of this pollution, rather than wastewater effluent. 

“Whereas before, we could measure the amount of organic nitrogen or phosphorus pollution in a river, we couldn’t really identify where pollution was coming from. With our new approach we can use the unique molecular fingerprint of different sources of pollution in freshwater to identify their source,” said Dr Andrew Tanentzap at Trent University School of the Environment, co-author of the report.

Traditional approaches involve separately measuring many indicators of ecosystem health, such as the level of organic nutrients or particular pollutants like nitrogen. These can indicate the condition of the water, but not why this state has arisen.

Dissolved organic matter is one of the most complex mixtures on Earth. It consists of thousands of individual molecules, each with their own unique properties. This matter influences many processes in rivers and lakes, including nutrient cycling, carbon storage, light absorption, and food web interactions – which together determine ecosystem function.

Sources of dissolved organic matter in freshwater include urban runoff, agricultural runoff, aerosols and wildfires.

“It’s possible to monitor the health of freshwater through the diversity of compounds that are present. Our approach can, and is, being rolled out across the UK,” said Tanentzap.

Fonvielle will now apply this technique to analysing water samples from farmland drainage ditches in the Fens, as part of a project run by the University of Cambridge’s Centre for Landscape Regeneration to understand freshwater health in this agricultural landscape.
