☆ In Coral Fossils, Searching for the First Glow of Bioluminescence
▼ + stars: | 2024-04-23 | by ( Sam Jones | ) www.nytimes.com time to read: +1 min

Bioluminescence is used throughout the animal kingdom, particularly in marine environments, to lure prey, startle predators and even act as camouflage in the surrounding light. “We always say it’s light-limited in the deep sea, but there are a lot of organisms that produce their own light,” said Andrea Quattrini, a zoologist at the Smithsonian National Museum of Natural History in Washington. The dazzling glow of bioluminescence is common in Octocorallia, also known as octocorals, a class of over 3,000 Anthozoa species including sea fans, sea pens and soft corals. The prevalence of bioluminescence in these sessile animals makes a lot of sense, Dr. Quattrini said: “They settle somewhere and they’re there.”How long organisms have been able to emit light is at the center of recent research by Dr. Quattrini and colleagues. Their latest study, published Tuesday in the journal Proceedings of the Royal Society B, resets the timing for the emergence of bioluminescence back to about 540 million years ago, from the existing understanding that it appeared in small marine crustaceans 267 million years ago.

☆ Foxes were once humans’ best friends, study says

Archaeologists originally uncovered the near-complete D. avus skeleton buried alongside a human at Cañada Seca, a site in northern Patagonia, in 1991. Parts of the D. avus specimen were buried alongside a human at Cañada Seca, a site in northern Patagonia. D. avus lived from the Pleistocene Epoch (around 2.6 million to 11,700 years ago) into the Holocene, becoming extinct about 500 years ago. With a similar diet to D. avus, dogs may have helped speed the foxes’ extinction by outcompeting them. Dogs could also have carried and transmitted diseases that sickened the foxes, Lebrasseur added.

But dogs were not the only ancient canines to become companions. Archaeologists have found traces of foxes living among early communities throughout South America. A team of researchers recently examined the fox’s bones, which were unearthed among the remains of dozens of hunter-gatherers. The team’s findings, published Tuesday in the journal Royal Society Open Science, posit that this fox lived alongside the humans it was buried with. “It’s a practice that had been suggested before, but to actually find it is a nice surprise.”

☆ All Orcas Are Classified as a Single Species. Should They Be?
▼ + stars: | 2024-03-26 | by ( Emily Anthes | ) www.nytimes.com time to read: +1 min

Killer whales are some of the most cosmopolitan creatures on the planet, swimming through every one of the world’s oceans. Although their habitats and habits vary widely, all killer whales are considered part of a single, global species: Orcinus orca. (Despite their common name, killer whales are actually part of a family of marine mammals known as oceanic dolphins.) In a paper published in the journal Royal Society Open Science on Tuesday, the scientists proposed giving new species designations to two groups of animals, one known as resident killer whales and the other often called Bigg’s killer whales. Although both types live in the eastern North Pacific, they have different diets: the resident orcas eat fish, with a particular predilection for salmon, while the Bigg’s orcas hunt marine mammals such as seals and sea lions.

☆ Feeling older than you are? It could be how you sleep

CNN —Not getting enough sleep may cause you to feel five to 10 years older than you really are, according to two new studies. A lack of energy and motivation can certainly contribute to feeling older while limiting a person’s ability to remain physically and socially active, both of which contribute to feeling young, Balter said. For every night of poor sleep during that time, people reported feeling about a quarter of a year older than their chronological age. “These findings support that sleep, a vital biological phenomenon, might hold the key to feeling young,” Balter and her colleagues wrote in the study. “If you suspect that your sleep deprivation is due to a sleep disorder such as insomnia or sleep apnea, it’s crucial to seek evaluation and treatment from a healthcare professional,” he said.

But that's in part down to their youth, with the oldest giant sequoia in the UK dating to 1863, UCL said in its report. By contrast, the oldest known giant sequoia in the US reached 3,266 years old, according to the National Park Service. UCL said giant sequoias "can potentially pull an average of 85 kilograms of carbon out of the atmosphere per year."

CNN —Researchers have found a new way in which great apes are similar to humans: they tease each other. Researchers found that all four species of great apes demonstrated “intentionally provocative behavior, frequently accompanied by characteristics of play,” according to the press release. The study details 18 different teasing behaviors, many of which were used to provoke a response or attract another ape’s attention. The authors also differentiate playful teasing, which is one-sided, from play, where both apes reciprocate. While primatologists had observed similar behaviors in the past, the study is the first to systematically study playful teasing, Laumer said.

Flight100, Virgin Atlantic's world first 100% Sustainable Aviation Fuel (SAF) transatlantic flight by a commercial airline is fuelled ahead of its take off from London Heathrow to New York JFK on Tuesday 28 November 2023. LONDON — The first trans-Atlantic flight using 100% sustainable aviation fuel departed London for New York on Tuesday as the industry seeks to prove the viability of greener air travel. Sustainable aviation fuel — also known as SAF — is an umbrella term for non-fossil-derived fuels, including biofuels derived from plant or animal materials, municipal waste and agricultural residues. It still produces emissions, but proponents argue the overall "lifecycle emissions" from the fuel are significantly lower than from regular petroleum-based fuel. There are relatively few SAF production plants or companies transporting it globally, with incentives for producers hampered by low margins.

CNN —For the first time, a transatlantic flight operated by a commercial airline will be powered by 100% Sustainable Aviation Fuel (SAF) — a type of plane fuel that bears the promise of a much lower climate impact than traditional ones. The flight is the latest in a series of recent tests involving 100% SAF. Days earlier, business jet maker Gulfstream completed what it billed as the world’s first transatlantic flight using 100% SAF. Large twin-engine jets have performed flights using 100% SAF on both engines before, but these flights involved military aircraft. “One flight on 100% alternative fuel isn’t going to change the fact that 99.9% of aviation fuel is fossil fuel and there’s no great option for feedstock (raw materials) that can be scaled up sustainably,” she says.

Their findings, published on Wednesday in the journal Royal Society Open Science, reveal that while the spiders quickly spotted the termites in the striped capes, they rarely attacked the striped termites, providing an explanation for why myriad other species use striking stripes to scare off predators. That’s where jumping spiders come in. With more than 6,500 species found worldwide, jumping spiders are voracious arachnids that feed on just about any invertebrate they come across. Dr. Taylor and her team studied two species of jumping spiders commonly found in Florida — the regal jumping spider, or Phidippus regius, and Habronattus trimaculatus. The researchers placed two termites of each cape variety in a petri dish with a jumping spider and recorded which termite the spiders looked at and which they ended up attacking.

Cheetahs are usually daytime hunters, but the speedy big cats will shift their activity toward dawn and dusk hours during warmer weather, a new study finds. While cheetahs only eat fresh meat, lions and leopards will sometimes opportunistically scavenge from smaller predators. But the new study found that on the hottest days, when maximum daily temperatures soared to nearly 45 degrees Celsius (113 degrees Fahrenheit), cheetahs became more nocturnal — increasing their overlapping hunting hours with rival big cats by 16%. In addition to competition with lions and leopards, cheetahs already face severe pressure from habitat fragmentation and conflict with humans. The fastest land animal, cheetahs are the rarest big cat in Africa, with fewer than 7,000 left in the wild.
