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.

DNA analysis sheds light on how Neanderthals disappeared
  + stars: | 2024-07-31 | by ( Katie Hunt | ) edition.cnn.com   time to read: +8 min
The analysis, published July 12 in the journal Science, showed that the two groups exchanged DNA at multiple points over the past 250,000 years, shedding light on how Neanderthals disappeared and potentially rewriting the story of how and when our Homo sapiens ancestors left Africa. Genetic detective workDuring the two earlier waves of interbreeding, the Neanderthal population absorbed human genes and the offspring stayed within Neanderthal groups, according to the new study. Russian archeologists digging inside Denisova cave located in the the Altai mountains that's been home to Neanderthals, early modern humans and the Denisovans. A skull found in Qafzeh Israel is believed to have belonged to an early modern human. The researchers’ analysis suggests that the Neanderthal population size at the time was 20% smaller than previously thought.

CNN —For many nations — not least the US — the upcoming Paris Olympics will take place against a background of deep political and social division. If you saw any of the European Athletics Championships events last month, you may well have been struck, as I was, by just how many Black athletes featured on podiums. At the Summer Olympics, the USA team will also feature numerous Black athletes, including gymnast Simone Biles, sprinter Sha’Carri Richardson and the (current) fastest man on earth, Noah Lyles. As you watch the Olympics this summer, take note of the sports in which Black people represent the USA and European countries. So no, Black athletes are not naturally better at some sports — they take the narrower opportunities open to them and work incredibly hard on their self-belief to make it to that podium.

A team of international academics successfully sequenced the genomes of each of the eight baobab species, examining their relationship with one another and concluded that they originated in Madagascar. "Avenue of the Baobabs" in Western Madagascar is one of the most spectacular collections of the unusual trees. Gavinevans/Creative CommonsOnly one baobab species is not included in the IUCN’s Red List of Threatened Species: A. digitata, which populates mainland Africa. The likelihood of finding fossil evidence to rubberstamp the conclusions of the genetic data is slim, Dr. Wan conceded. So perhaps these majestic trees may retain some of their mystery after all.

Blood biomarkers of telltale signs of early Alzheimer’s disease in the brain of his patient, 55-year-old entrepreneur Simon Nicholls, had all but disappeared in a mere 14 months. “I don’t use the term ‘reverse.’ I don’t know what reverse means when it comes to the field of Alzheimer’s,” Isaacson said. ‘It was time to turn to my brain’Slowly, Nicholls’ heart condition began to improve, but the bad news didn’t end there. A brain scan found telltale signs of vascular damage in Nicholls’ brain, which occurs when the tiniest blood vessels are starved of oxygen. Not only was Nicholls blood negative for amyloid and tau, the test suggested that his brain amyloid might be normal, with no distinguishable signs of the disease.

Michael C. Jensen, an economist and Harvard Business School professor whose evangelizing for stock options, golden parachutes and leveraged buyouts helped to reshape modern capitalism and empower Wall Street’s greed-is-good era, died on April 4 at his home in Sarasota, Fla. The death was confirmed by his daughter Natalie Jensen-Noll. “Mike was a kind of born proselytizer,” Eugene F. Fama, a University of Chicago professor and Nobel laureate in economics who collaborated with Professor Jensen, said in an interview. “He was very sure of himself in terms of his ideas being correct and, you know, pathbreaking.”They were also incendiary. In his book “The Golden Passport: Harvard Business School, the Limits of Capitalism, and the Moral Failure of the MBA Elite” (2017), the journalist Duff McDonald called Professor Jensen an “instrument of intellectual violence” who “created a Frankenstein that no one knows how to kill.”

A severely ill 54-year-old woman earlier this month became the second person to receive a kidney transplanted from a genetically modified pig, surgeons at NYU Langone Health in New York announced on Wednesday. The patient, who had both heart failure and kidney failure, was given the organ on April 12, just eight days after receiving a mechanical heart pump. Surgical teams at NYU Langone carried out the two procedures over the course of nine days. The kidney came from a genetically engineered pig provided by United Therapeutics Corporation, a biotech company. The pig carried a gene for producing a sugar called alpha-gal that had been “knocked out,” or blocked.

Why don’t humans have tails?

One of those led to shorter tails; the more of that protein the genes produced, the shorter the tails. A tail as old as timeFor modern humans, tails are a distant genetic memory. While Alu’s role “seems to be a very important one,” other genetic factors likely contributed to the permanent disappearance of our primate ancestors’ tails,” Xia said. In their experiments, the researchers found that when mice were genetically engineered for tail loss, some developed neural tube deformities that resembled spina bifida in humans. “Maybe the reason why we have this condition in humans is because of this trade-off that our ancestors made 25 million years ago to lose their tails,” Yanai said.

For nearly 79 years, Anne Walker Collingwood knew little about her father, an American soldier who died about three months after she was born while fighting near Hücheln, Germany, during World War II. Her father, Second Lt. Gene F. Walker, was the commander of a tank that was hit by an anti-tank round and caught fire in November 1944. The attack is believed to have killed Lieutenant Walker, 27, instantly, but heavy fighting in the area prevented the surviving crew members from recovering his body. At home in Indiana, Ms. Collingwood’s family told her little about her father. Then in July, Ms. Collingwood received an unexpected call: the military had identified her father’s remains.

The evolutionary effects of redlining are percolating through urban wildlife populations, but they are not yet set in stone. Not only does the composition of wildlife differ between neighborhoods, but so does the incidence of people looking for wildlife. Diego Ellis Soto, a Ph.D. student at Yale, found that across the country, historically redlined neighborhoods were the least studied areas for bird diversity. Mr. Ellis Soto, who is from Uruguay, said he was shocked when he arrived in New Haven and saw how segregated the city was. “How can we protect what we don’t have information for?” Mr. Ellis Soto said.

The mysterious illness is described as an “atypical canine infectious respiratory disease,” the Oregon Department of Agriculture said in a November 9 news release. In other words, dogs with the unidentified illness show similar signs of an upper respiratory disease but generally don’t test positive for common respiratory diseases. The Washington Animal Disease Diagnostic Laboratory has also reported cases of a mysterious canine disease, the lab’s director told CNN in an email. While the news may be concerning, “We suggest caution rather than worry,” the Oregon Veterinary Medical Association’s website says. While this particular disease is unusual, “Periodic outbreaks of Canine Infectious Respiratory Disease Complex (CIRDC) can occur in a dog population.

New economic rules shatter US bonds’ crystal ball

Yield curve “inversions” belong to the latter group. At first sight, they are right: Yield curve inversions have been a consistent predictor of future downturns. Yield curve inversions take place when the yield on short-dated government debt climbs higher than that on longer-term bonds. Lower long-dated bond yields are seen as a sign that investors predict lower rates due to an economic downturn. As such, yield curve inversions have become a popular forward indicator of economic recessions.

However, over half of the sequences within the Y chromosome, the smallest and most complicated of the 46 human chromosomes, remained unknown. Now, the same group of researchers has filled in the missing information, publishing a complete Y chromosome sequence Wednesday in the journal Nature. “This new analysis will allow us to better understand the regions of the Y chromosome that have regulatory functions and may encode mRNA and proteins.”Many people begin to lose their Y chromosome in some of their cells as they age, particularly those cells that undergo rapid turnover, such as blood cells. Having a complete Y chromosome genetic reference may help scientists and doctors further explore this potential link. “However, it has been questioned whether loss of the Y chromosome is a biomarker of biological aging or whether loss of the Y chromosome has a direct effect on the health of men,” he said.

What lies at the bottom of the ocean?

What lies at the bottom of the oceanWhile what’s considered the deep ocean extends from 3,280 feet to 19,685 feet (1,000 meters to 6,000 meters) beneath the surface, deep-sea trenches can plunge to 36,000 feet (11,000 meters), according to the Woods Hole Oceanographic Institution in Massachusetts. Alessandro Mancini/Alamy Stock PhotoWhy mapping the ocean is so challengingFrom a strictly scientific perspective, touristic trips to the ocean floor do little to advance our understanding of the ocean’s mysteries. “We want to go to the highest, the lowest, the longest.”But only a “very small percentage of the deep ocean, and even the middle ocean, has been seen by human eyes — an infinitesimal amount. “However, 150 years of modern oceanography have led to better understanding of many aspects of the ocean such as the life it contains, its chemistry and its role in the Earth system.”Mapping the ocean “helps us to understand how the shape of the seafloor affects ocean currents, and where marine life occurs,” Rogers added. Researchers say the ocean and the life it contains could provide answers to some of medicine’s biggest challenges, such as antibiotic drug resistance.

A 2022 study found night owls were more sedentary, had lower aerobic fitness levels, and burned less fat at rest and while active than early birds. Night owls were also more likely to be insulin-resistant, meaning their muscles required more insulin to be able to get the energy they need, the study showed. Studies have revealed night owls may take more risks and are more likely to skip breakfast and eat more later in the day. Night owls also have higher levels of visceral body fat in the abdominal region, a key risk factor for type 2 diabetes and heart disease. “The strongest reset for the circadian system is bright light,” Zee said.

A time of celebration in Guyana as it prepared to mark its independence day this week turned to mourning on Monday after at least 20 people, many of them children, were killed when a fire engulfed a girls’ dormitory at a school in the central part of the South American country. The country’s president described the fatal blaze as “horrific” and a “major disaster.”The ages of the victims are not known, but students enrolled at the school are between 12 and 16. Several others were injured in the fire, which broke out late Sunday in Mahdia, a gold mining town about 120 miles southwest of the capital, Georgetown. Seven students in critical condition were being evacuated to the capital. “The focus now is on the children to ensure that we do everything, to give them as much help as we can,” President Mohamed Irfaan Ali told journalists early Monday at Ogle airport, also known as Eugene F. Correia International Airport, where he was organizing a “full-scale emergency” plan.
It probably doesn't taste like woolly mammoth, a meat specialist and mammoth DNA researcher said. The Belgian startup Paleo says it added woolly mammoth myoglobin to a plant-based burger. The mammoth meatball doesn't have either of those elements from woolly mammoth. Mammoth myoglobin doesn't necessarily bring mammoth flavorThough he didn't taste it, Ryall said everyone could smell the meatball while it was cooking. So why make a mammoth meatball that doesn't taste like mammoth?
A Belgian startup says it added woolly mammoth DNA to a plant-based burger. The mammoth myoglobin gave it a more intense taste and aroma, and a richer color, the CEO said. But it's unclear when, if ever, mammoth protein will make it to grocery store shelves. The Belgian startup Paleo says it added woolly mammoth protein to a plant-based burger — and that the result was more intense than with cow. Sanctorum said the company added the mammoth protein to several different versions of plant-based burgers and tasted it.
