Nearly 27 percent of the people in the country are 65 or older. NPR’s Ina Jaffe visited Japan and tells Rachel Martin what she learned about why the population is aging.
The first hamburger cooked with labmade meat didn’t get rave reviews for taste. But the test tube burger, rolled out to the press in 2013, has helped put a spotlight on the question of how the U.S. government will regulate the emerging field of cellular agriculture, which uses biotechnology instead of animals to make products such as meat, milk, and egg whites.
Once people realized that opioid drugs could cause addiction and deadly overdoses, they tried to use newer forms of opioids to treat the addiction to its parent. Morphine, about 10 times the strength of opium, was used to curb opium cravings in the early 19th century. Codeine, too, was touted as a nonaddictive drug for pain relief, as was heroin.
The fight against the Zika virus has a new weapon: the genetically engineered mosquito. It’s recently been approved by federal regulators and may soon be available in parts of the U.S. that are confronting the virus, like Puerto Rico and Miami.
Large genomic databases are indispensable for scientists looking for genetic variations associated with diseases. But they come with privacy risks for people who contribute their DNA. A 2013 study1 showed that hackers could use publicly available information on the Internet to identify people from their anonymized genomic data.
One study now caught in that eddy is a report reporting behavioral problems in children born to women who took acetaminophen (popular brand name: Tylenol) during pregnancy. Evie Stergiakouli and George Davey Smith at the University of Bristol published it Monday in JAMA Pediatrics. They studied about 7,800 women and their children over the course of more than seven years.
The cardiovascular health of U.S. children is strikingly dismal, so says a new statement from the American Heart Association. Specifically, less than 1 percent of American children meet the organization’s definition of ideal cardiovascular health, according to statement author Dr. Julia Steinberger, a professor in pediatrics and director of pediatric cardiology at the University of Minnesota in Minneapolis.
Roslyn Lewis was at work at a dollar store here, pushing a heavy cart of dog food, when something popped in her back: an explosion of pain. At the emergency room the next day, doctors gave her Motrin and sent her home.
Middle- and lower-income countries now have a higher rate of hypertension than high-income countries. Worldwide, the prevalence of hypertension is at a record high, according to a new study in the journal Circulation.
The CRISPR–Cas9 tool enables scientists to alter genomes practically at will. Hailed as dramatically easier, cheaper and more versatile than previous technologies, it has blazed through labs around the world, finding new applications in medicine and basic research.
The federal government announced plans Thursday to lift a moratorium on funding of certain controversial experiments that use human stem cells to create animal embryos that are partly human.
Many medical studies involving children never end up being put to use because scientists frequently don’t publish the results of their work, according to an analysis published online Thursday.
Scientists have discovered 15 genome sites — the first ever — linked to depression in people of European ancestry. Many of these regions of depression-linked genetic variation turn out to be involved in regulating gene expression and the birth of new neurons in the developing brain.
It was one of the most mind-bending scientific reports in 2014: Injecting old mice with the plasma portion of blood from young mice seemed to improve the elderly rodents’ memory and ability to learn. Inspired by such findings, a startup company has now launched the first clinical trial in the United States to test the antiaging benefits of young blood in relatively healthy people. But there’s a big caveat: It’s a pay-to-participate trial, a type that has raised ethical concerns before, most recently in the stem cell field.
Investigators identify the bad lines of genetic code that may lead to the disease
According to the World Health Organization, being transgender is a mental illness. But that could soon change, as WHO prepares a new edition of the International Classification of Diseases (ICD), its global codebook that influences national disease diagnostic manuals worldwide. The current version, ICD-10, has been around since 1990 and ICD-11 is expected to be approved in 2018.

Dolly the Sheep started her life in a test tube in 1996 and died just six years later. When she was only a year old, there was evidence that she might have been physically older. At five, she was diagnosed with osteoarthritis. And at six, a CT scan revealed tumors growing in her lungs, likely the result of an incurable infectious disease. Rather than let Dolly suffer, the vets put her to rest.
The European Union is beefing up protections for volunteers in phase I clinical trials in the wake of a disastrous clinical study in Rennes, France, that resulted in the death of one volunteer and the hospitalization of five others. On 21 July, the European Medicines Agency (EMA) in London announced in a “concept paper” that it wants to improve strategies to identify and reduce risks in “first-in-human” (FIH) studies on healthy volunteers. EMA is asking for input from stakeholders.

Americans aren’t very enthusiastic about using science to enhance the human species. Instead, many find it rather creepy
A new method known as behavioral activation (BA) is effective and can be cheaper than cognitive behavioral therapy.
When you’re pregnant, going to the doctors can be exciting. You get to find out if you’re having a boy or a girl. Maybe hear the baby’s heart beat. But in southern Africa, many women find out something else.
Neuroscientists acting as cartographers of the human mind have devised the most comprehensive map ever made of the cerebral cortex, the part of the brain responsible for higher cognitive functions such as abstract thought, language and memory.

Women undergoing in vitro fertilization have long worried that the procedure could raise their risk for breast cancer.
The Florida health department said late Tuesday that it is investigating what could be the first case of locally spread Zika virus in the continental United States.
Watching a person die from cardiac arrest in an intensive care unit is devastating. It’s especially so when the person is a woman in her 40s who has been smothered to death by her own weight — and we doctors can do nothing to save her.

Of the hundreds of monkeys in the University of Wisconsin’s primate center, a few — including rhesus macaque 827577 — are now famous, at least among scientists tracking the Zika virus. Since February, a team led by David H. O’Connor, the chairman of the center’s global infectious diseases department, has been conducting a unique experiment in scientific transparency. The tactic may presage the evolution of new ways to respond to fast-moving epidemics.
The Senate is set to approve a bill intended to change the way police and health care workers treat people struggling with opioid addictions.
