A single genetic tweak that occurred among our ancestors 25 million years ago means humans today are unable to grow a tail, according to a new study. Scientists knew that a gene called TBXT was involved in the snipping of the tail. Asep Supriatna/Getty ImagesWandering DNA snipped off our tailsThe solution, they found, was in a type of "jumping gene" called an Alu element. Scientists found two Alu elements around a part of the TBXT gene, called Exon 6. Scientists tested their findings by inserting Alu sequences in mice.

March 2, 2024Neanderthals may have vanished 40,000 years ago, but they are no strangers to us today. But there’s no such familiarity with the Denisovans, a group of humans that split from the Neanderthal line and survived for hundreds of thousands of years before going extinct. In a new review paper, anthropologists tally all of the fossils that have been clearly identified as Denisovan since the first discovery in 2010. Nevertheless, many scientists are growing increasingly fascinated by Denisovans. “I find Denisovans way more interesting,” said Emilia Huerta-Sánchez, a geneticist at Brown University.

☆ 5 tips for navigating childhood obesity

Editor’s note: Season 9 of the podcast “Chasing Life With Dr. Sanjay Gupta” explores the intersection between body weight and health. With children, doctors define obesity a bit differently than they do with adults. Severe obesity is having a BMI equal to or greater than the 120th percentile. “Most people who are heavy by the age of 5 or 6 will tend to continue to have problems with body weight throughout adolescence and into adulthood,” Yanovski said. “We know that those individuals will therefore accrue the greatest risks from their higher body (fat) because they’re going to continue to have high body weight throughout the years,” he said.

☆ Mystery of whale song unraveled by scientists, study says
▼ + stars: | 2024-02-22 | by ( Amarachi Orie | ) edition.cnn.com time to read: +6 min

How baleen whales, which include humpback whales, are able to sing underwater has eluded scientists since whale songs were first discovered more than 50 years ago. A baleen whale’s larynx is shaped differently from other mammals. This structural adaptation allows the leviathan to breathe massive amounts of air in and out when they go to the surface, according to the study. Air sacs also evolved in a way that may allow a baleen whale to recycle air while creating vocal sounds, according to researchers. This means that most boating noises mask calls between baleen whales, reducing the distance over which they can communicate.

☆ Happy New Year of the Dragon - or Loong?

This year, it’s the Year of the Dragon, or more accurately, the “Year of the Loong,” says Chinese state media, using its preferred term for the mythical beast. The Chinese “loong” conjures positivity, nobleness and fortune and therefore should be distinguished linguistically from its Western cousin, state media argues. Chinese media has dedicated coverage and airtime to promote the new nomenclature over the past week or so, though both “dragon” and “loong” are being used interchangeably in English-language reports. “Transcribing long into English ‘loong’ would cause more problems and confusion than translating it as ‘dragon’,” he wrote. He noted that “some patriotic and political sources in the Sinosphere” have been peddling the concept that the Western dragon is fearful.

☆ Great apes tease each other just like humans do, says new study

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.

Romantic kisses have long been celebrated in songs, poems and stories, commemorated in art and film. Modern scholars therefore concluded that romantic kisses likely originated in India. Across thousands of cuneiform tablets kissing isn’t the most mentioned topic, “but it is attested regularly,” he said. But Arbøll and Rasmussen suspected that romantic kissing became accepted in Bronze Age Europe, and not because of migration alone. Even today, many cultures shun romantic kissing, Arbøll and Rasmussen reported.

☆ ‘Moths to a flame’: Insect behavior around light isn’t about attraction, scientists say

Gaining a better understanding of the impact of artificial light on these winged creatures is crucial as light pollution plays an increasing role in the decline of global insect populations, the researchers wrote. Artificial light confuses nocturnal insectsWhen artificial light does not interfere, nocturnal insects keep their backs pointed toward whatever direction is brightest, which is typically the sky versus the ground. By using insect-scale motion-capture cameras, the researchers determined that the flying insects exhibited three consistent behaviors: orbiting, stalling and inverting. Moths and other insects can become trapped in a disorienting orbit around artificial light sources such as street lamps and porch lights. The new findings could help with conservation by fueling research on how to minimize the effects of light pollution on the insects, Dombroskie said.

The participants had their blood pressure monitored for a day before beginning treatment and again after nine months of weekly tirzepatide injections. The results showed a significant decrease in the participants’ systolic blood pressure, the top number in blood pressure readings, which is a strong predictor of heart disease. It works similarly to semaglutide, the active compound in the weight loss drug Wegovy and its sister diabetes drug, Ozempic. Although there are effective blood pressure medications available, only about a quarter of people with hypertension have adequately controlled blood pressure, Hall said. He views the weight loss effect of the drug as a pleasant side effect that will make people more likely to take their medication.

Modern humans, or homo sapiens, weren’t previously known to have lived as far north as the region where the tools were made. “The Ranis cave site provides evidence for the first dispersal of Homo sapiens across the higher latitudes of Europe. It also shows that Homo sapiens, our species, crossed the Alps into the cold climes of northern and central Europe earlier than thought. Using the same technique, the team also managed to identify human remains among bones excavated during the 1930s.

The 13-year group, known as Brood XIX, or the Great Southern Brood, is the largest periodical cicada brood, stretching across the southeastern United States. The Northern Illinois Brood, or Brood XIII, emerges every 17 years. Periodical cicadas are smaller and mostly black, with bright red eyes and orange-tinged wings and legs. Billions of cicadas are expected this spring as two different broods — Broods XIX and XIII — emerge simultaneously. However, predictions of a cicadapocalypse — in which Brood XIII and Brood XIX show up at the same place at the same time — are probably an exaggeration.

During their three-week mating season, they sleep three hours a night less than usual. Females live just two years, while males die shortly after the breeding season. Still, for most animals, loss of sleep is a serious business. The effect of the loss of sleep doesn't reset in the morning but instead is compounded every night. "Three hours of sleep loss is not lethal in any animal we know of," Lesku said.

Scientists based in Australia have found that mouse-sized male antechinus trade sleep to leave more time for reproductive activities during mating season, with one male who was monitored halving his sleep time during that period. Non-breeding dusky antechinus spend an average of 15.3 hours of the day asleep, according to the researchers. “Sleep restriction in breeding male antechinus is likely to be an adaptive behavioral response driven by strong sexual selection,” the paper said. To study the semelparous marsupials, researchers examined two antechinus species: dusky antechinus (Antechinus swainsonii) and wild agile antechinus (Antechinus agilis) both captive and wild. Lesku said researchers would next like to examine how male antechinus deal with restricting their sleep for three weeks.
