And ‘X’ users say eating disorder content flourished on the platform. On Oct. 7, Hamas militants stormed the same base where Lifshitz was previously stationed, killing 15 young women in their assault. Many of the users identified as teen girls and young women, some as young as 13, NBC News found. Three users said that they’ve been exposed to eating disorder posts and communities on X through their algorithm-driven “For You” page, despite not knowingly engaging with such content previously. Despite X’s moderation, at least seven more communities featuring content promoting eating disorders and self-harm were identified.

Two American scientists were jointly awarded the Nobel Prize for Medicine or Physiology on Monday for their groundbreaking work on how genes behave. Victor Ambros and Gary Ruvkun discovered microRNA, which the Nobel Assembly describes as "a fundamental principle governing how gene activity is regulated." The tiny microRNA molecules play a crucial role in determining how different cells — which have the same chromosomes, essentially their instruction manual — have different characteristics. "The answer lies in gene regulation, which allows each cell to select only the relevant instructions," the Nobel announcement said. But subsequent work, including the discovery of another microRNA in 2000, proved that there are more than a thousand genes for different microRNAs in humans.

CNN —This year’s Nobel Prize in physiology or medicine has been awarded to Victor Ambros and Gary Ruvkun for their work on the discovery of microRNA, a fundamental principle governing how gene activity is regulated. Their research revealed how genes give rise to different cells within the human body, a process known as gene regulation. The Nobel Prize committee announced the prestigious honor, seen as the pinnacle of scientific achievement, in Sweden on Monday. Ruvkun conducted his research at Massachusetts General Hospital, and is a professor of genetics at Harvard Medical School.

☆ Sea robins are fish that use their legs to ‘taste’ the seafloor
▼ + stars: | 2024-09-26 | by ( Ashley Strickland | ) edition.cnn.com time to read: +8 min

CNN —Some types of sea robins, a peculiar bottom-dwelling ocean fish, use taste bud-covered legs to sense and dig up prey along the seafloor, according to new research. A species of sea robins called Prionotus carolinus studied by the researchers used their legs for walking, digging and sensing the seafloor. And the fish that lacked sensory capabilities and used their legs mainly for walking were striped sea robins, or Prionotus evolans. The digging sea robins had shovel-shaped legs that were covered in protrusions called papillae, which are similar to the taste buds on our tongues. Both researchers said they are keen to uncover the exact mechanisms behind the evolution of the sea robins’ sensory appendages.

A decade after the dairy discovery on strikingly intact remains mummified by the Taklamakan Desert’s arid conditions, scientists have extracted and sequenced DNA from the 3,600-year-old cheese, the oldest in the archaeological record. Fu is director of the ancient DNA laboratory at the Institute of Vertebrate Paleontology and Paleoanthropology in Beijing. The researchers recovered animal and microbe DNA from the kefir cheese discovered on the Tarim Basin mummies. Fu and her colleagues also sequenced the bacterial genes in the ancient kefir cheese, revealing insights into how probiotic bacteria evolved over the past 3,600 years. “Ancient DNA analysis, especially on microbes, is fraught with technical problems, mostly stemming from contamination by modern bacteria,” he added.

I felt a tremendous sense of guilt when my mother unexpectedly died on Christmas Eve in 2004 at the young age of 48. I think some of it stems from the guilt I've felt over her death. "But it's not a given that if your mom or dad died young, you're definitely going to die young." "Guilt is there because our culture does not provide children, especially young ones, with the reason why their parents died," she explains. Soon, she says, I will begin to realize that just because my mother died young doesn't mean I will, too.

☆ Is your kid a picky eater? It’s probably not your fault, study shows

But those failing to tempt their child to eat their broccoli can take solace, as research has found that picky eating is largely down to genes rather than environment. They found that non-identical twin pairs were much less similar when it came to picky eating than identical twin pairs. Picky eating “often causes a lot of stress for the children and their families,” Moritz Herle, a researcher at King’s College London and one of the study’s lead authors, said. The study found that environmental factors can, however, have an impact on a child’s food pickiness when they are a toddler. Abigail Pickard, a researcher in developmental child psychology at Aston University who wasn’t involved in the research, told CNN that picky eating is “quite common” in children.

☆ Ancient DNA adds to evidence debunking theory of Easter Island collapse

CNN —Rapa Nui, also known as Easter Island, never experienced a ruinous population collapse, according to an analysis of ancient DNA from 15 former inhabitants of the remote island in the Pacific Ocean. Settled by Polynesian seafarers 800 years ago, Rapa Nui, today part of Chile, has hundreds of monumental stone heads that echo of the past. But that theory remains contentious, and other archaeological evidence suggests that Rapa Nui was home to a small but sustainable society. Easter Island genomesTo investigate Rapa Nui’s history further, researchers sequenced the genomes of 15 former residents who lived on the island during the past 400 years. But the ancient genomes add to a growing body of evidence that the idea of a self-inflicted population collapse on Easter Island is a false narrative, said Matisoo-Smith, who wasn’t involved in the study.

Grotte Mandrin is the only known site to have been home to alternating groups of both Homo sapiens and Homo neanderthalensis. “The Thorin population spent 50,000 years without exchanging genes with other Neanderthal populations,” Slimak said in a news release. DNA from Homo sapiens fossils from that time show that these early arrivals interbred with Neanderthals — traces of those encounters remain in present-day human populations. Archaeologists have excavated more of Thorin’s remains: 31 teeth, part of the jaw and five finger bones, so far. It’s the only known site to have been home to alternating groups of both Homo sapiens and Neanderthals, plus the earliest evidence of bow and arrow use outside Africa.

LOG-related genes are found in all plants, even dating back to mosses, which are regarded as the first dry-land plant, Lippman said. “(LOG genes) have been repeatedly co-opted (a biological shift in a trait’s function) in different plant species for the formation of prickles, and also repeatedly lost in lineages where prickles are lost.
