इंसानों के खत्म होने के बाद पृथ्वी पर राज करेंगे ऑक्टोपस, अपनी काबिलियत से बसाएंगे नई सभ्यता

World News: दुनिया खत्म होगी, और शायद उससे पहले इंसान और जीवन भी खत्म हो जाएगा. यह सम्भावना तो सभी को पता है. पर क्या आपने एक बात पर कभी गौर किया है. दुनिया में आए हर महाविनाश के बाद जीवन फिर से पनपा है और उससे पहले जो जानवर दुनिया पर राज कर रहे थे वे खत्म हो गए. ऐसा डायनासोर, ऊनी मैमथ सहित कई बड़े जानवरों के साथ हुआ था कि उनके विलुप्त होने के बाद भी जीवन पनपता रहा. पर क्या होगा जब इंसान खत्म…

"During an archaeological dig in a desert area north of Jerusalem 40 years ago, a seed was discovered which was determined to be in pristine condition but had obviously seen many a year.

Now, despite falling from its parent 1,000 years ago, it has grown into a mature tree, and botanists examining it believe it may be an extinct species that was used for medicinal purposes for thousands of years—even receiving a nod in the Bible.

Neither Israeli botanists, nor Dr. Sarah Sallon, a physician who founded the Louis L. Borick Natural Medicine Research Center at Hadassah University Medical Center in Jerusalem, could determine what species it was from simply from the seed covering. So they did what nature intended—they planted it.

Using a well-documented technique that saw 2,000-year-old date palm fruit pits germinate, Dr. Sallon soaked the seed in hormones, liquid fertilizer, and water, and then planted it in a pot of sterile seed; then waited.

Despite its genetic code being exposed to environmental stressors for over 1,000 years, the seed sprouted after 5 weeks. The shoot was protected by a caplike feature called an operculum. As the shoot grew, the operculum was shed—leaving something for the team to radiocarbon date. It narrowed down the age of the almost 10-centuries-old seed to between the years 993 an 1202.

Fast forward 14 years and the plant has become a 10-foot-tall tree. Dr. Sallon shared images of the tree, its bark, and its leaves with botanists around the world. One expert suggested it belonged to the genus Commiphora, found across the Arabian Peninsula and parts of Africa. A genetic analysis subsequently revealed this was the case, but a perfect match was lacking.

Pictured: The tree, now 14 years old.

Dr. Sallon and her team thought it was an extinct species known from history as Judean Balsam, but the best way to confirm that suspicion would be to have some aromatic traces similar to the resins of the myrrh tree to which it is related. However, no such fragrant compounds were detected.

Instead, the chemical analysis of the leaves identified a group of phytochemicals known as guggulterols which have been observed in a related species called Commiphora wightii that’s known to possess certain cancer-fighting properties in its resin.

A medicinal balm, the origin of which is not known, is mentioned in multiple historical texts including the Bible as ‘tsori,’ and rather than the fragrant Judean Balsam, it’s this tsori that Dr. Sallon and her team believe they have found.

They must wait until the tree, now 14 years old, produces flower or fruit to know for sure if it’s an extinct species, and if so, how to perhaps keep it alive.

Dr. Louise Colville, senior research leader in seed and stress biology at Royal Botanic Gardens, Kew, in London who wasn’t involved in the research, told CNN that it was a major accomplishment to grow a seed that old and possibly lead to a resurrection of this Biblical botanical.

“What’s surprising in this story is it was just a single seed and to be able to have one chance for that to germinate is extremely lucky,” she said.

“Working in a seed bank, seeing the potential for that extreme longevity gives us hope that banking and storing seeds that some at least will survive for very long periods of time.”"

Note: This is such a good demonstration of why seed banks are so important!! They give us such real and massive hope for deextinction and the revival of endangered species.

Multiple attempts to reintroduce captive-born ‘alalā to Hawaii’s Big Island have been unsuccessful, in large part because of the ‘io, or Hawaiian hawk, the ‘alalā’s last surviving natural predator. But now new hope is taking wing: a fresh class of five young ‘alalā has been released into the wild on the slopes of the Haleakalā volcano on the island of Maui, where ‘io are absent.

I need you all to appreciate how crazy it is to have watched the scimitar horned oryx go from a poster child for "it only exists in zoos" to merely endangered (not even critically endangered!) over my lifetime.

So many heroic people contributed ridiculous amounts of time and effort to make this captive breeding and reintroduction effort a success.

This is HUGE news! Sea otters have been absent from Oregon shorelines for more than a century due to overhunting for fur. While Washington and California have healthy populations, Oregon hasn't seen any new otters move in, other than the occasional transient. This is due largely to the fact that they are not normally migratory animals, and so are more likely to stick around relatively close to their birthplaces. Since all the sea otters of Oregon were exterminated to make coats and other fur products, there was no remaining population to rebuild locally.

However, reintroduction could make a difference by deliberately relocating sea otters from other areas to Oregon, particularly in places that have lots of food for them, like sea urchins. This grant would fund research in finding the best places to reintroduce them and the best existing populations to draw from, among other tasks that need to be addressed before the otters can meet their new homes.

This grant is an incredibly important move forward in returning this keystone species to a part of its native range. Bringing back sea otters would vastly improve the health of kelp forests in the ocean, which are currently being decimated by an overpopulation of sea urchins. In turn, healthier kelp forests means better marine biodiversity offering more food and shelter for a wider range of species, giving them more resilience in the years to come.

1. Four new cheetah cubs born in Saudi Arabia after 40 years of extinction

“[T]he discovery of mummified cheetahs in caves […] which ranged in age from 4,000 to as recent as 120 years, proved that the animals […] once called [Saudi Arabia] home. The realisation kick-started the country’s Cheetah Conservation Program to bring back the cats to their historic Arabian range. […] Dr Mohammed Qurban, CEO of the NCW, said: […] “This motivates us to continue our efforts to restore and reintroduce cheetahs, guided by an integrated strategy designed in accordance with best international practices.””

2. In sub-Saharan Africa, ‘forgotten’ foods could boost climate resilience, nutrition

“[A study published in PNAS] examined “forgotten” crops that may help make sub-Saharan food systems more resilient, and more nutritious, as climate change makes it harder to grow [current staple crops.] [… The study identified 138 indigenous] food crops that were “relatively underresearched, underutilized, or underpromoted in an African context,” but which have the nutrient content and growing stability to support healthy diets and local economies in the region. […] In Eswatini, van Zonneveld and the World Vegetable Center are working with schools to introduce hardy, underutilized vegetables to their gardens, which have typically only grown beans and maize.”

3. Here's how $4 billion in government money is being spent to reduce climate pollution

“[New Orleans was awarded] nearly $50 million to help pay for installing solar on low to middle income homes [… and] plans to green up underserved areas with trees and build out its lackluster bike lane system to provide an alternative to cars. […] In Utah, $75 million will fund several measures from expanding electric vehicles to reducing methane emissions from oil and gas production. [… A] coalition of states led by North Carolina will look to store carbon in lands used for agriculture as well as natural places like wetlands, with more than $400 million. [… This funding is] “providing investments in communities, new jobs, cost savings for everyday Americans, improved air quality, … better health outcomes.””

4. From doom scrolling to hope scrolling: this week’s big Democratic vibe shift

“[Democrats] have been on an emotional rollercoaster for the past few weeks: from grim determination as Biden fought to hang on to his push for a second term, to outright exuberance after he stepped aside and Harris launched her campaign. […] In less than a week, the Harris campaign raised record-breaking sums and signed up more than 100,000 new volunteers[….] This honeymoon phase will end, said Democratic strategist Guy Cecil, warning the election will be a close race, despite this newfound exuberance in his party. [… But v]oters are saying they are excited to vote for Harris and not just against Trump. That’s new.”

5. Biodegradable luminescent polymers show promise for reducing electronic waste

“[A team of scientists discovered that a certain] chemical enables the recycling of [luminescent polymers] while maintaining high light-emitting functions. […] At the end of life, this new polymer can be degraded under either mild acidic conditions (near the pH of stomach acid) or relatively low heat treatment (> 410 F). The resulting materials can be isolated and remade into new materials for future applications. […] The researchers predict this new polymer can be applied to existing technologies, such as displays and medical imaging, and enable new applications […] such as cell phones and computer screens with continued testing.”

6. World’s Biggest Dam Removal Project to Open 420 Miles of Salmon Habitat this Fall

“Reconnecting the river will help salmon and steelhead populations survive a warming climate and [natural disasters….] In the long term, dam removal will significantly improve water quality in the Klamath. “Algae problems in the reservoirs behind the dams were so bad that the water was dangerous for contact […] and not drinkable,” says Fluvial Geomorphologist Brian Cluer. [… The project] will begin to reverse decades of habitat degradation, allow threatened salmon species to be resilient in the face of climate change, and restore tribal connections to their traditional food source.”

7. Biden-Harris Administration Awards $45.1 Million to Expand Mental Health and Substance Use Services Across the Lifespan

““Be it fostering wellness in young people, caring for the unhoused, facilitating treatment and more, this funding directly supports the needs of our neighbors,” said HHS Secretary Xavier Becerra. [The funding also supports] recovery and reentry services to adults in the criminal justice system who have a substance use disorder[… and clinics which] serve anyone who asks for help for mental health or substance use, regardless of their ability to pay.”

8. The World’s Rarest Crow Will Soon Fly Free on Maui

“[… In] the latest attempt to establish a wild crow population, biologists will investigate if this species can thrive on Maui, an island where it may have never lived before. Translocations outside of a species’ known historical range are rare in conservation work, but for a bird on the brink of extinction, it’s a necessary experiment: Scientists believe the crows will be safer from predators in a new locale—a main reason that past reintroduction attempts failed. […] As the release date approaches, the crows have already undergone extensive preparation for life in the wild. […] “We try to give them the respect that you would give if you were caring for someone’s elder.””

9. An optimist’s guide to the EV battery mining challenge

““Battery minerals have a tremendous benefit over oil, and that’s that you can reuse them.” [… T]he report’s authors found there’s evidence to suggest that [improvements in technology] and recycling have already helped limit demand for battery minerals in spite of this rapid growth — and that further improvements can reduce it even more. [… They] envision a scenario in which new mining for battery materials can basically stop by 2050, as battery recycling meets demand. In this fully realized circular battery economy, the world must extract a total of 125 million tons of battery minerals — a sum that, while hefty, is actually 17 times smaller than the oil currently harvested every year to fuel road transport.”

10. Peekaboo! A baby tree kangaroo debuts at the Bronx Zoo

“The tiny Matschie’s tree kangaroo […] was the third of its kind born at the Bronx Zoo since 2008. [… A] Bronx Zoo spokesperson said that the kangaroo's birth was significant for the network of zoos that aims to preserve genetic diversity among endangered animals. "It's a small population and because of that births are not very common," said Jessica Moody, curator of primates and small mammals at the Bronx Zoo[, …] adding that baby tree kangaroos are “possibly one of the cutest animals to have ever lived. They look like stuffed animals, it's amazing.””

In a deeply disturbing finding that has sent shockwaves throughout the nation and the world, officials from the U.S. Fish and Wildlife Service confirmed Thursday that cows have gone extinct.

After fielding numerous questions from the public about where all the cows had gone, the federal agency reportedly conducted an in-depth survey of dairy farms, cattle ranches, and open pasture land across six continents, eventually concluding that not a single member of the domesticated ungulate species remains anywhere on the planet.

#2545 - Hieraaetus moorei - Haast's Eagle

The largest eagle ever known to exist. Almost certainly the pouākai of Māori mythology. They certainly would have paid attention to it since it was big enough to consider humans as particularly stupid Moa who stood around in the open.

Here's some talon marks in a Moa hipbone.

Originally described as Harpagornis moorei by Julius von Haast in 1871, from the Greek harpax, meaning "grappling hook". DNA analysis later showed that this bird was actually related to the much smaller little eagle (Hieraaetus morphnoides) and booted eagle (Hieraaetus pennatus) and not the large wedge-tailed eagle (Aquila audax) of Australia.

It probably evolved from the little eagle 1.8 million to 700,000 years ago, which means it increased ten to fifteen times in size - the largest, fastest evolutionary increase in average weight of any known vertebrate species. There were no other large predators in New Zealand, and an abundance of giant flightless prey.

It had a relatively short wingspan for a bird in its weight class. Females were estimated to span 2.6 m, possibly up to 3 m. It seems likely they pursued prey into dense forests, like the goshawks and harpy eagle.

The eagles most likely became extinct in the 1400s, after the Māori hunted their usual prey to extinction. Maori oral tradition about the birds persist to today, with late 1800s records saying it had red, black and white plumage with "black feathers tinged with yellow or green" and "a bunch of red feathers on its head".

Pairing frogs and toads together might conjure memories of Arnold Lobel’s beloved characters — dressed to the nines in caramel coats and polyester — biking off toward adventure. 

But in the animal world, frogs and toads on nearly every continent are facing a much more harrowing adventure: a decades-long fight against a mysterious fungal virus that has afflicted over 500 amphibian species. 

Since the 1990s, scientists estimate that the chytridiomycosis disease caused by the fungal pathogen Bd (Batrachochytrium dendrobatidis) has led to the extinction of 90 amphibians. One of the lost species includes the Panamanian golden frog, which hasn’t been spotted in the wild since 2009. 

Fortunately, a new research study has finally pinpointed the virus that has been infecting fungal genomes for decades. 

“Bd is a generalist pathogen and is associated with the decline of over 500 amphibian species…here, we describe the discovery of a novel DNA mycovirus of Bd,” wrote Mark Yacoub — the lead author of the study and a microbiology doctoral student at the University of California, Riverside. 

In an interview with UC Riverside News, Yacoub said that he and microbiology professor Jason Stajich observed the viral genome while studying the broader population genetics of mycovirus (viruses of fungi). 

The discovery will undoubtedly have monumental impacts on future amphibian conservation efforts. This includes the possible launching of new research studies into fungal species strains, the practice of cloning and observing spores, and engineering a solution to the virus. 

But Yacoub cautioned that this is only the beginning. 

“We don’t know how the virus infects the fungus, how it gets into the cells,” Yacoub said. “If we’re going to engineer the virus to help amphibians, we need answers to questions like these.”

Still, as scientists strengthen conservation efforts to save frogs and toads (and salamanders too!) they also appear to be saving themselves. Yacoub pointed out several amphibian species around the world have begun exhibiting resistance to Bd. 

“Like with COVID, there is a slow buildup of immunity,” Yacoub explained. “We are hoping to assist nature in taking its course.”

Pictured: A Golden poison frog — one of the many species endangered by chytridiomycosis — in captivity.

Why are frogs and toads so important?

From the get go, every amphibian species plays an important role in their local ecosystem. Not only are they prey for a slew of animals like lizards, snakes, otters, birds, and more, but in an eat-or-be-eaten world, frogs and toads benefit the food chain by doing both. 

Even freshly hatched tadpoles — no bigger than a button — can reduce contamination in their surrounding pond water by nibbling on algae blooms. 

As they grow bigger (and leggier), amphibians snack on whatever insect comes their way, greatly reducing the population of harmful pests and making a considerable dent in the transmission malaria, dengue, and Zika fever by eating mosquito larvae. 

“Frogs control bad insects, crop pests, and mosquitoes,” Yacoub said. “If their populations all over the world collapse, it could be devastating.” 

Yacoub also pointed out that amphibians are the “canary in the coal mine of climate change,” because they are an indicator species. Frogs and toads have permeable skin, making them sensitive to changes in their environment, and they also rely on freshwater. 

When amphibians vanish from an ecosystem, it’s a symptom of greater environmental issues...

Herpetologist Maureen Donnelly echoed Yacoub’s sentiments in an interview with Phys Org, noting that when it comes to food chains, biodiversity, and environmental impact, the role of frogs and toads should not be overlooked. 

“Conservation must be a global team effort,” Donnelly said. “We are the stewards of the planet and are responsible for all living creatures.”

Many penguin species huddle together in massive colonies, but pairs of yellow-eyed penguins go out of their way to be alone, nesting deep in New Zealand’s scrublands and forests out of sight of other penguins. When pairs reunite at the nest after one has been away fishing, they greet each other with a piercing cry that Thor Elley, an endangered avian species researcher at the University of Otago with Māori roots, likens to “a whistling tea kettle rolling down a hill.” The species’ Māori name, hoiho, roughly translates to “noise shouter.” 

Screaming and antisocial behavior may not seem like beloved traits, but these penguins are revered in Māori culture as taonga, or treasure, even gracing the country’s $5 bill. They are “protected by sacred origins,” Elley says.

But one of New Zealand’s favorite endemic birds is also one of its rarest. The International Union for Conservation of Nature estimates that only between 2,600 and 3,000 hoiho exist. About a third live on New Zealand’s South Island and nearby Stewart Island. The rest inhabit sub-Antarctic islands some 300 miles to the south. In the past 15 years, the northern population has plummeted by roughly 75 percent, and researchers expect that group could disappear within the next two decades if the trend continues. 

The decline stems from a litany of factors. Red cod, once a pillar of the hoiho diet, has become scarce, and blue cod, although larger, are harder to catch, eat and feed to their chicks than other staple fish. Penguins also drown each year in commercial gillnets. And a pair of diseases, avian diphtheria and, since 2019, a mysterious and fatal respiratory illness, also infect virtually every chick. Janelle Wierenga, a veterinary scientist at the University of Otago and Massey University, says potential vaccines and drugs are likely years away. 

To keep the species afloat, wildlife hospitals and conservation groups have taken the radical step of removing every single hoiho chick on the South Island from its nest and placing it in human care for its first week or so of life. Chicks are treated with antibiotics to heal the mouth sores caused by avian diphtheria. They’re also fed fish smoothies to boost their strength. It’s unclear how, but this extra care prevents chicks from developing the respiratory disease. “I’ve got the feeling that the diseases are a secondary problem, and the primary problem is the penguins don’t get the sustenance they need,” says Thomas Mattern, an ecologist at the University of Otago. 

In 2023, the Dunedin Wildlife Hospital hand-reared 214 hoiho chicks. Without human intervention, 50 to 70 percent of those chicks would have died, Lisa Argilla, the hospital’s senior wildlife veterinarian and director, estimates. But these herculean efforts can only offer a short-term reprieve. “We are trying to buy this population as much time as we can,” she says. “You feel like you’re fighting a losing battle, but we couldn’t live with ourselves if we didn’t fight for these penguins.”

Endangered Species Sightings from This Year

This is thought to be the first time in over 20 years that a blue whale was spotted off the Coast of Massachusetts.

I highly recommend watching the video and listening to the reaction of the people on the whale watching boat--the cheers and emotion in some of their voices, especially the woman saying "I'm trying not to" when someone jokingly tells her not to cry.

This is the first time ever that a mother clouded leopard with two cubs has been spotted on a game cam!

"After being considered regionally extinct for over a century, giant anteaters have been spotted roaming once again in Brazil's Rio Grande do Sul state. Scientists have concluded these returned natives ventured over from Argentina's Ibera Park, where conservationists have released around 110 rescued and captive-bred anteaters since 2007."

Over 100 years and the anteaters are finally coming home!
