Why ‘Fetal Personhood’ Is Roiling the Right

As I.V.F. grew in popularity, so did the concerns of its opponents. Standard practice involves creating multiple embryos, which are screened for genetic abnormalities, and the ones that appear healthiest can be transferred. Extra embryos are often frozen; by one count, there are a million and a half frozen embryos in the United States. After a designated time period, they may be donated to science or destroyed, just as the Catholic Church feared.The anti-abortion movement won a partial victory for protecting life at conception in 2001, when President George W. Bush banned the use of federal funds for embryonic stem cell research, but President Barack Obama reversed the policy eight years later.Starting in the late 2000s, voters rejected ballot initiatives to enshrine fetal personhood in at...

C.D.C. Shortens Isolation Period for People With Covid

Americans with Covid or other respiratory infections need not isolate for five days before returning to work or school, the Centers for Disease Control and Prevention said on Friday, a striking sign of changing attitudes toward the coronavirus.People with respiratory illnesses may resume daily activities if they have been fever-free for at least 24 hours without the aid of medications and if their symptoms are improving, agency officials said. Acknowledging that people can be contagious even without symptoms, the C.D.C. urged those who end isolation to limit close contact with others, wear well-fitted masks, improve indoor air quality and practice good hygiene, like washing hands and covering coughs and sneezes, for five days.The guidelines apply to Covid, influenza and respiratory syncyti...

R.S.V. Vaccines May Slightly Increase Risk of Rare Neurological Condition

Vaccines for respiratory syncytial virus may have caused a few cases of Guillain-Barré syndrome, a rare neurological condition, federal health officials said on Thursday.The numbers were small, on the order of two cases per 100,000 vaccinated people or fewer, and much more data is needed to pin down the risk, the officials said. In May 2023, the Food and Drug Administration approved two vaccines against R.S.V.: Abrysvo, by Pfizer, and Arexvy, by GSK.In June, rather than recommend the shots to all older adults, the Centers for Disease Control and Prevention recommended that adults aged 60 or older might opt to receive a single dose of an R.S.V. vaccine in consultation with their health care providers. Fewer than 10 million doses had been administered by Feb. 16.The new safety data, disclose...

Lead-Tainted Applesauce Highlights Failings in Food Safety System

The tainted applesauce might have gone unnoticed for even longer had it not been for a family in North Carolina.Early last summer, Nicole Peterson and Thomas Duong were alarmed by their young children’s blood-lead levels in a routine screening. Within weeks, the levels had doubled.Ms. Peterson said the couple worked with the local health department as they tried to determine what could be hurting their children. We “weren’t sleeping and we’re not eating — like this is driving us crazy,” said Ms. Peterson. She and her husband are suing Dollar Tree, where they bought the applesauce, and WanaBana, a U.S. distributor led by Austrofood officers.A Dollar Tree spokeswoman said the company is committed to the safety of the products it sells. Austrofood said that it had relied on its supplier’s cer...

Your Inhalers and EpiPens Aren’t Very Healthy for the Environment

Single-use insulin pens changed Brian Brandell’s life.Growing up with Type 1 diabetes in the 1970s, he had to carry glass syringes and vials of insulin wherever he went. So in 1985, when Novo Nordisk debuted a disposable prefilled pen that combined several doses of medication with a syringe, Mr. Brandell readily adopted the new device.“They were a godsend,” he recalled.But more recently, he began weighing the effects of all the plastic in the pens he had thrown away over the years, and the potential harm to people and his surroundings.“I’m using this lifesaving product,” he said with frustration, “but in order for me to use it, I’ve got to be willing to damage the environment.”It’s no secret that the world has a plastic problem. The versatile, durable and cheap material is clogging the wor...

Severe Frostbite Gets a Treatment That May Prevent Amputation

The first time Dr. Peter Hackett saw a patient with frostbite, the man died from his wounds. It was in Chicago in 1971, and the man had gotten drunk and passed out in the snow, his fingers so frozen that gangrene eventually set in.Dr. Hackett later worked at Mount Everest Basecamp, on Denali, Alaska, and now in Colorado, becoming expert in treating cold-weather injury. The experience was often the same: There was not much to do about frostbite, except rewarm the patient, give aspirin, amputate in severe cases and, more often, wait and accept that six months later the patient’s body might “auto-amputate” by naturally shedding a dead finger or toe.His mentor in Anchorage used to say, “Frostbite January, Amputation July,” remembered Dr. Hackett, clinical professor at the Altitude Research Cen...

Roger Guillemin, 100, Nobel-Winning Scientist Stirred by Rivalries, Dies

Roger Guillemin, a neuroscientist who was a co-discoverer of the unexpected hormones with which the brain controls many bodily functions, died on Wednesday at a senior living facility in San Diego. He was 100.His death was confirmed by his daughter Chantal Guillemin.Dr. Guillemin’s career was marked by two spectacular competitions that ruffled the staid world of endocrinological research. The first was a 10-year tussle with his former partner, Andrew V. Schally, which ended in a draw when the two shared half of the Nobel Prize in Physiology or Medicine in 1977. (The other half went to the American medical physicist Rosalyn Yalow for unrelated research.)The second competition began shortly afterward when Wylie Vale Jr., Dr. Guillemin’s longtime collaborator and protégé, set up a rival labor...

Study of Patients With a Chronic Fatigue Condition May Offer Clues to Long Covid

Jennifer Caldwell was active and energetic, working two jobs and taking care of her daughter and her parents, when she developed a bacterial infection that was followed by intense lightheadedness, fatigue and memory problems.That was nearly a decade ago, and she has since struggled with the condition known as myalgic encephalomyelitis/chronic fatigue syndrome, or ME/CFS. Ms. Caldwell, 56, of Hillsborough, N.C., said she went from being able to ski, dance and work two jobs as a clinical research coordinator and a caterer to needing to stay in bed most of every day.“I haven’t been right since, and I haven’t worked a day since,” said Ms. Caldwell, whose symptoms include severe dizziness whenever her legs are not elevated.The condition has also “messed me up cognitively,” she said. “I can’t re...

How Sleep Affects Your Mood: The Link Between Insomnia and Mental Health

It started with mild anxiety.Emily, who asked to be identified only by her first name because she was discussing her mental health, had just moved to New York City after graduate school, to start a marketing job at a big law firm.She knew it was normal to feel a little on edge. But she wasn’t prepared for what came next: chronic insomnia.Operating on only three or four hours of sleep, it didn’t take long for her anxiety to ramp up: At 25, she was “freaking nervous all the time. A wreck.”When a lawyer at her firm yelled at her one day, she experienced the first of many panic attacks. At a doctor’s suggestion, she tried taking a sleeping pill, in the hopes that it might “reset” her sleep cycle and improve her mood. It didn’t work.Americans are chronically sleep deprived: one-third of adults ...

Two 45-minute daily workouts. One gallon of water. 10 pages of a nonfiction book. A diet. No “cheat meals” or alcohol. For 75 days.And if you mess up, you have to start from the beginning.Sound like a lot? It’s supposed to be. The program, called 75 Hard, is meant to build mental toughness.
