Khelif has become a flashpoint for an often misinformed debate about how women are allowed to compete in sports. As Khelif prepares for her next fight on Saturday, here’s what to know:Who is Imane Khelif? Algeria's Imane Khelif (R), is seen after defeating Italy's Angela Carini in the women's 66kg preliminary boxing match at the 2024 Summer Olympics in Paris on Thursday. Many athletes have written in support of Khelif, including Irish boxer Amy Broadhurst – who fought and beat Khelif in the World Championships. Female athletes that have differences of sexual development (DSD) are often subject to such tests.

“Gentoo penguins are big climate change winners in the Antarctic,” Heather Lynch told me. Conversely, the more flexible gentoo penguins keep moving farther and farther south, chasing new prey, and even abandoning nests to increase the odds of long-term survival. Julian Quinones/CNNThe gentoo population has exploded by as much as 30,000% in just a few years. Bill Weir/CNNHere lieth the lesson of the camel and the gentoo: Heat will move us, one way or another. I just know River won’t be satisfied without a magic plot twist that somehow saves all creatures great and small.

☆ Chinstrap penguins take thousands of 4-second naps a day so they can stay alert and guard their newborns around-the-clock, researchers say

Chinstrap penguins take catnaps instead sleeping for a long period of time, researchers found. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. Chinstrap penguins, named for the thin line of black facial feathers resembling a chinstrap, usually lay their eggs in pebble nests in November. For the first time, the scientists tracked the sleeping behavior of chinstrap penguins in an Antarctic breeding colony by attaching sensors that measure brain waves. "For these penguins, microsleeps have some restorative functions — if not, they could not endure," he said.

☆ Chinstrap penguins survive on more than 10,000 naps a day, study finds

CNN —The art of nodding off appears to have been mastered by breeding chinstrap penguins, who take more than 10,000 naps a day, with each nap lasting an average of four seconds, according to a new study. They observed that the penguins in the colony engaged in more than 600 bouts of microsleep an hour. A 1986 study found captive, nonbreeding emperor penguins to have fragmented sleep called “drowsiness,” which also resembles the microsleep pattern of the breeding chinstrap penguins. He added that through these short bursts of sleep the penguins could “sleep and remain vigilant” while incubating. “I think that’s why it’s important to study sleep.

Winston Churchill famously napped, and companies like Zappos encourage employees to doze on the job to improve their effectiveness. But nobody beats the chinstrap penguin for its power-napping prowess.

☆ Extreme sleep behavior documented in cute Antarctic chinstrap penguins

Guarding their nests is serious business for these medium-sized penguins, with predatory seabirds called brown skuas on the prowl. But this species, scientists said on Thursday, has devised an ingenious way of getting sufficient sleep without compromising vigilance. The researchers documented extreme sleep behavior in these flightless birds. "Penguins do not display any obvious negative consequence of sleep fragmentation," Libourel said. During incubation, skuas prey on penguin eggs, particularly on a colony's periphery.

WASHINGTON (AP) — It's a challenge for all new parents: Getting enough sleep while keeping a close eye on their newborns. For some penguins, it means thousands of mini-catnaps a day, researchers discovered. Chinstrap penguins in Antarctica need to guard their eggs and chicks around-the-clock in crowded, noisy colonies. These short “microsleeps,” totaling around 11 hours per day, appear to be enough to keep the parents going for weeks. “For these penguins, microsleeps have some restorative functions — if not, they could not endure,” he said.

Tiny but bountiful, Antarctic krill make up one of the planet’s largest biomasses, nourishing everything from fish to marine mammals and seabirds. At Steinberg’s lab, researchers are examining how warming oceans — Antarctic krill need water colder than 4 degrees Celsius (39 Fahrenheit) to survive — are altering krill’s life cycle. However, a leading marine biologist the industry once relied on to burnish its environmental credentials has since denounced krill fishing. She accepted with the hope that she could help mitigate the effects of krill fishing on the Antarctic ecosystem. Today, she believes that krill fishing should be banned.

Images of Dominic Pezzola, nicknamed “Spazzolini,” using the police riot shield to first breach the Capitol building quickly became a symbol of the violence that day. “The reality is you were the one who did it,” District Judge Timothy Kelly said during the hearing Friday. “You were the one who smashed that window in and let people begin to stream into the Capitol building and threaten the lives of our lawmakers. Pezzola was the only one of the five Proud Boys defendants not convicted of seditious conspiracy. Two of Pezzola’s codefendants, Joseph Biggs and Zachary Rehl, were sentenced Thursday to 17 and 15 years in prison respectively.
