Americans have received billions of doses of vaccines for everything from measles to the flu. In 30 years, very few injury claims have been filed with the federal government.

New research in mice has suggested that a disrupted gut microbiome may contribute to the chance of breast cancer cells spreading.

It’s increasingly clear that our situation is worse than we’ve been told, perhaps far, far worse. By Kollibri terre Sonnenblume.

The Earth's biodiversity is decreasing at a faster rate than ever before. Why is this happening?

If a dog has eyes that seem to be telling you something or demanding your attention, it could be evolution's way of manipulating your feelings. Researchers have found that dogs have evolved muscles around their eyes, which allow them to make expressions that particularly appeal to humans.

Stress and long working hours are regrettably common among early-career researchers, reveals a survey by the group the Young Academy of Europe.

Scientists in the FinnBrain research project of the University of Turku discovered that the gut microbes of a 2.5-month-old infant are associated with the temperament traits manifested at six months of age. Temperament describes individual differences in expressing and regulating emotions in infants...

At 16, Huwe Burton confessed to killing his mother. He was still in shock from discovering her body when New York City police began to interrogate him. After hours of being threatened and cajoled, he told the police what they wanted to hear. He soon recanted, knowing he was innocent and hoping the justice system would clear him.

Changes in pornography use appear to be unrelated to sexual satisfaction, according to new longitudinal research that examined high school students.

Loneliness is a “disease”, associated with an increased risk of death equivalent to smoking 15 cigarettes a day. Strides have been made in understanding what form of loneliness is damaging (a lack of close relationships with other people, rather than a lack of relationships per se), but ways to tackle loneliness are badly needed.

New research confirms that the alterations in consciousness associated with very low doses of lysergic acid diethylamide (LSD) are not just the result of a placebo effect. But the findings suggest that these “microdoses” might not have many benefits. Preliminary research had indicated that microdosing could improve several aspects of psychological functioning.

Back in 1980 when Harlem was still a byword for poverty, criminality and the decline of New York City, black men in the neighbourhood had a worse chance of living to the age of 65 than men in Bangladesh did. At that time Harlem’s residents—almost all of them black, and many of them poor—died of heart disease at double the rate of whites. They died of liver cirrhosis, brought on by alcoholism or hepatitis, at ten times the rate of whites.

When you think of animal fat, what comes to mind? Unsightly blobs of cellulite? Artery-clogging strips of gristle to be trimmed off your steak and tossed into the trash? Or a sophisticated substance that contains within it the secret to human intelligence?

Heisenberg's famous Uncertainty Principle is put to the test to see if things really are uncertain in the quantum world.

It’s not just you, it’s nearly everyone. Roughly 88% of Americans use a second device, like a phone or a tablet, while watching TV, according to the longtime internet researcher and venture capitalist Mary Meeker. She released her annual internet trends report today (June 11).

Scientists are still debating when and where dogs were domesticated, but there’s one thing most of them agree on: Early canines were working animals. Dogs evolved from gray wolves earlier than 15,000 years ago—before humans settled down in permanent villages—and they likely helped us hunt small game like deer and rabbits and pulled sleds or other transport equipment across vast plains.

A gene that gives Salmonella resistance to antibiotics of last resort has been found in a sample taken from a human patient in the U.S.

Some languages — like English — are tricky to pick up easily. Young children learning to read and write English often need to identify patterns in words to be able to read and spell them. For example, knowing the “Magic E” syllable pattern can allow a child to understand why an E at the end of a word like “rate” significantly alters the word’s sound from “rat.”

Study finds elk have the means to adapt to changing climate cues, but migratory shifts may have unknown ripple effects throughout the region

That gold on your ring finger is stellar – and not just in a complimentary way. In a finding that may overthrow our understanding of where Earth’s heavy elements such as gold and platinum come from, new research by a University of Guelph physicist suggests that most of them were spewed from a lar

At a conservative estimate, people around the world are consuming a credit card's-worth of microplastic every week, according to a new study.

What makes movies that are sad or scary so popular? For that matter, why do people enjoy roller-coasters, bungee jumping, or any of the countless other activities that seem to serve no purpose except to make people feel terrified, however briefly? Is there a positive benefit to exposing yourself to these kinds of intense negative experiences? According to recent studies, there may be.

We like to view modern medicine as based on rigorous science, and while it certainly beats the various dangerous alternatives out there, sometimes physicians still end up adopting practices based on little evidence.

The first study of a new treatment in humans demonstrates a noninvasive, harmless cancer killer

They’ve been linked to disease and overeating. Could our microbiome explain why?

People with polydactyly — who have more than five fingers per hand — have better dexterity and rewired brains that can control these extra digits.

New research in mice uncovers a previously unknown "pathway toward healthy aging." A circulating protein from the blood of young mice led to health improvements and visible signs of rejuvenation when researchers gave it to aging mice.

A Cornell-Environmental Defense Fund research team has found there is more methane being emitted from the ammonia fertilizer industry than the EPA had estimated for all industrial processes in the U.S.

Naturopathy, sometimes referred to as "natural medicine," is a largely pseudoscientific approach said to "assist nature" [1], "support the body's own innate capacity to achieve optimal health" [2], and "facilitate the body's inherent healing mechanisms." [3] Naturopaths assert that diseases are the body's effort to purify itself, and that cures result from increasing the patient's "vital force." (Whatever that is!)

You might think they are disgusting. But our war against intestinal worms has damaged our immune systems and mental health. By William Parker.

Record-breaking Midwest rainfall washed tons of fertilizer and sewage water out to sea, contributing to a devastatingly large patch of polluted water, scientists say.

Researchers say Pfizer should have published Enbrel analysis. Pfizer says its decision was based on science.

Call it the “Little Bog of Horrors.” In what is believed to be a first for North America, biologists at the University of Guelph have discovered that meat-eating pitcher plants in Ontario’s Algonquin Park wetlands consume not just bugs but also young salamanders.

The psychologists behind the research hope their insights can help the autistic community and those around them in adapting support available.

Young blood has mysterious powers to improve cognition in older animals. Two proteins that boost structures in neurons seem to be behind the effect
