With COVID-19 infections becoming more common, experts have recently urged doctors to prescribe the antiviral drug Paxlovid more than they have been to minimize patients’ symptoms and reduce the chance that they’ll develop severe disease. The drug is authorized for people at higher risk of developing severe COVID-19, including those who are older and people with underlying health conditions. But many patients who have taken Paxlovid have reported developing rebound infections shortly after: testing positive again for the virus after first supposedly clearing the infection and testing negative. Studies have documented that the repeat positive tests are due to the same virus that caused the original infection returning again, rather than a new infection. In 2022, the U.S. Cent…
Allie Phillips never wanted to be a politician, but she had always wanted to be a mom of two. Whenever Phillips asked her 5-year-old daughter, Adalie, what she wanted to be when she grew up, Adalie would say, “A big sister.” So when Phillips found out she was pregnant again in Nov. 2022, Adalie was thrilled. “Her eyes got big and her jaw just dropped open,” Phillips recalled. “Every night after that, she sang Twinkle Twinkle, Little Star to my belly. She’d kiss my belly every night before bed.” Phillips and her husband planned to name the new baby Miley Rose.
But at a routine anatomy scan when she was around 19 weeks pregnant, doctors told Phillips that the fetus had significant problems with its kidney, stomach, bladder, heart, lungs, and brain. These conditions were…
At the start of the COVID-19 pandemic, as hospitals facilitated goodbyes over iPads and funeral homes buried dead without services, families were left with a uniquely isolating grief, devoid of the rituals that traditionally surround death.
For Black Americans, who were 1.9 times more likely than white Americans to die of COVID-19 at the start of the pandemic, this stifled grief fits into a long history of unacknowledged pain. Dating back to slavery, when scientific journals claimed that Black people had higher pain tolerances, to now, as the maternal mortality rate for Black women is 2.9 times that of white women, Black Americans have long faced medical discrimination. The pandemic—and the racial justice reckoning that erupted after the death of George Floy…
NASA picked a very good morning to return from the moon. It was 50 years ago today that the crew of Apollo 17 landed in the Taurus Littrow Valley on the lunar surface, where they planted the last of six flags Apollo crews would leave behind to mark their moments in history. Today, the space agency planted a new, if symbolic flag, when the Artemis 1 mission’s Orion crew capsule splashed down in the Pacific Ocean 320 km (200 mi.) off the coast of Baja California, Mexico, at 9:40 a.m. Pacific Time. The safe return marked the end of a 25-day lunar orbital mission, proving the flight-worthiness of the Orion spacecraft, which is expected to carry a crew of astronauts on a circumlunar journey during Artemis 2, in 2024.คำพูดจาก A baby zebrafish is just half the size of a pea. A recent look inside its transparent brain, however, offers clues to the far bigger mystery of how we remember—and how we forget. In an experiment that yielded insights into memory and the brain, a team of researchers at the University of Southern California taught the tiny creature to associate a bright light with a flash of heat, a temperature change the fish responded to by trying to swim away. Using a custom-designed microscope, the team then captured images of the animals’ brains in the moments before and after they learned to associate the light and the heat. It’s the first known look at how a living vertebrate’s brain restructures itself as the animal forms a memory. In the image published with t…
