Women’s brains are superior to men’s in at least in one respect — they age more slowly. And now, a group of researchers reports that they have found a gene in mice that rejuvenates female brains. Humans have the same gene. The discovery suggests a possible way to help both women and men avoid cognitive…
Postpartum depression affects about one in every seven women who give birth, but little is known about what happens in the brains of pregnant women who experience it. A new study begins to shed some light. Researchers scanned the brains of dozens of women in the weeks before and after childbirth and found that two…
Five years ago Italian researchers published a study on the eruption of Mount Vesuvius in A.D. 79. that detailed how one victim of the blast, a male presumed to be in his mid 20s, had been found nearby in the seaside settlement of Herculaneum. He was lying facedown and buried by ash on a wooden…
Scientists have long struggled to understand how human language evolved. Words and sentences don’t leave fossils behind for paleontologists to dig up. A genetic study published on Tuesday offers an important new clue. Researchers found that, between 250,000 and 500,000 years ago, a gene known as NOVA1 underwent a profound evolutionary change in our ancestors….
In early February, Vishvaa Rajakumar, a 20-year-old Indian college student, won the Memory League World Championship, an online competition pitting people against one another with challenges like memorizing the order of 80 random numbers faster than most people can tie a shoelace. The renowned neuroscientist Eleanor Maguire, who died in January, studied mental athletes like…
Eleanor Maguire, a cognitive neuroscientist whose research on the human hippocampus — especially those belonging to London taxi drivers — transformed the understanding of memory, revealing that a key structure in the brain can be strengthened like a muscle, died on Jan. 4 in London. She was 54. Her death, at a hospice facility, was…
The first great white shark was found dead in August 2023 on a beach in a national park on Prince Edward Island, Canada: a young male, 500 pounds, 8 feet 9 inches from snout to tail. Park workers soon arrived with a pickup truck, loaded the carcass and drove it to a cooler at the…
The Food and Drug Administration approved a new medication Thursday to treat pain from an injury or surgery. It is expensive, with a list price of $15.50 per pill. But unlike opioid pain medicines, it cannot become addictive. That is because the drug, suzetrigine, made by Vertex Pharmaceuticals and to be sold as Journavx, works…
When a person dies, more than just their physical belongings remain behind; there are memories, experiences, and perspectives that can never be returned. These non-physical components of a person’s life form the essence of who they are, but after a person dies, their memories appear to disappear along with them. The question thus arises: would…
“In the beginning, everyone thought they were going to find this one breakthrough pain drug that would replace opioids,” Gereau said. Increasingly, though, it’s looking like chronic pain, like cancer, could end up having a range of genetic and cellular drivers that vary both by condition and by the particular makeup of the person experiencing…
