☆ These scientists want to safeguard Earth’s species by cryogenically preserving them on the moon
▼ + stars: | 2024-08-05 | by ( Jack Guy | ) edition.cnn.com time to read: +4 min

CNN —A group of scientists has devised a plan to safeguard Earth’s species in a cryogenic biorepository on the moon. In order to reach the required temperatures on earth, a supply of liquid nitrogen, electricity and human staff are required. To reduce this risk, Hagedorn and the team thought about how cryopreservation could be achieved passively, which is impossible on Earth, and alighted on the moon. “We aren’t saying what if the Earth fails – if the Earth is biologically destroyed this biorepository won’t matter,” Hagedorn said in the statement. Sally Keith, a senior lecturer in Marine Biology at Lancaster University, who was not involved in the research, had similar concerns.

Olympic officials on Friday tried urgently to rebut what they described as widespread “misinformation” that had turned a 46-second Olympic boxing match at the Paris Games into a forum for fierce debates and complicated questions about biology and competitive advantage in women’s sports. Mr. Adams stressed at a news conference that Khelif is not transgender. “There has been some confusion that somehow it’s a man fighting a woman,” Mr. Adams said. “The answer is yes,” according to their eligibility, passport and history. Khelif won her opening bout on Thursday when her Italian opponent, Angela Carini, refused to continue, and after she was cleared to compete in the Olympics despite being suddenly disqualified during last year’s world championships in a dispute about her eligibility.

☆ How did a rose get its prickles? A new study has answers

Prickles have been around for at least 400 million years, dating back to when ferns and their relatives emerged with some bearing prickles on their stems. Lonely Guy genesBy removing prickles from various species, including roses and eggplants, the authors found that a LOG gene was responsible for the prickles in about 20 types of plants studied. 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. For agricultural purposes, removing prickles could make harvesting easier and pave the way to get lesser-known produce into grocery stores.

Newfound fossils of the extinct arthropod Odaraia alata recently provided scientists with a first glimpse of Odaraia’s jawlike structures, called mandibles. He conducted the research at the Royal Ontario Museum while pursuing a doctoral degree in the University of Toronto’s department of ecology and evolutionary biology. For the new investigation, the researchers examined around 150 fossils collected by Royal Ontario Museum during expeditions between 1975 and 2000. The carapace folded over Odaraia’s limbs, so it may have been unable to walk on the seafloor, according to the Royal Ontario Museum.

The newly FDA approved Alzheimer's treatment Leqembi is prepared at Abington Neurological Associates in Abington, PA., on Tuesday, November 7, 2023. The breakthrough Alzheimer's drug Leqembi slowed disease progression in patients over three years, demonstrating the need for them to stay on the treatment long term, according to new data released Tuesday by Japanese drugmaker Eisai. The study results on Leqembi, which Eisai shares with Biogen , also found that a patient's Alzheimer's disease worsens after they stop treatment. The results are a first glimpse at what Alzheimer's patients' future could look like on therapies such as Leqembi, which is currently taken twice a month through an infusion. By 2050, the number of Alzheimer's patients is projected to rise to almost 13 million in the U.S.

The frequency may also affect your gut microbiome and risk of chronic disease, a new study has found. Self-reported bowel movement frequency was separated into four groups: constipation (one or two bowel movements per week), low-normal (three to six weekly), high-normal (one to three per day) and diarrhea. The authors believe their findings are “preliminary support for a causal link between bowel movement frequency, gut microbial metabolism, and organ damage,” according to a news release. It’s also possible a person’s gut microbiome could be influencing bowel movement frequency. Bowel movement frequency also isn’t the most ideal measure of bowel function, he said.

I just assumed that Nashville was part of the great temperate deciduous forests that once covered much of the eastern half of the United States. When I went looking for the once-endangered Tennessee coneflower in 2019, I found them in a rocky glade surrounded by grasslands blooming with wildflowers. And if there are grasslands here now, surely there must have been grasslands here in the past. Today nearly all those Southern prairies — along with nearly all the other types of Southern grassland ecosystems, and nearly all the plants and animals they supported — are gone. In a study published in 2021, a team of scientists including Dr. Estes identified 118 major types of grassland ecosystems in the South.

It's entirely possible that there are Greenland sharks still living today that were swimming in the North Atlantic Ocean at the time. Some theories include the shark's slow growth rate and low metabolic rate, but research is ongoing. Scientists hope that unlocking the secrets of how these fish age could help humans live longer, healthier lives. "We want to look closely at some of these hallmarks to determine if the Greenland shark shows any signs of traditional aging," he said. While Greenland sharks' remarkable aging process has allowed them to survive centuries, it could also be a double-edged sword as their environment rapidly changes.

Because shark skeletons are made of cartilage, they do not fossilize well, typically leaving archaeologists only teeth and few skeletal remains to find. Lamniformes also includes the modern species of megamouth, sand, goblin and basking sharks, among others. “The crushing teeth together with the gigantic size make Ptychodus a very unique shark,” Amadori said. … Modern durophagous sharks (that consume hard-shelled organisms) are demersal, feeding on or near the bottom.

CNN —Sex and gender are often conflated or equated in everyday conversations, and most American adults believe a person’s gender is determined by sex assigned at birth. But a new study of nearly 5,000 9- and 10-year-olds found that sex and gender map onto largely distinct parts of the brain. The researchers on the new study defined sex as what was assigned to the child at birth. They also hope to see how different cultures affect a person’s gender and their brain development. The study did not look at whether sex or gender were congruent or incongruent in any study participant.

All three of us were turning left — two flesh-and-blood drivers and my robot — when the two humans violated a basic traffic rule by swinging wide and turning into the right hand lane. The Tesla hugged the inside lane, as the driver manual indicates is the proper rule of the road. On the other hand, my son is less likely than the Tesla’s software to suddenly disengage and just stop steering altogether (requiring me to take over).
