More than a century ago, Pavlov trained his dog to associate the sound of a bell with food. Ever since, scientists have assumed the dog learned this through repetition. The more times the dog heard the ...

New analysis from a WHO global expert committee on vaccine safety has found that, based on available evidence, no causal link exists between vaccines and autism spectrum disorders (ASD). The conclusion reaffirms WHO’s position that childhood vaccines do not…

A new study on aortic stenosis, the most common form of heart valve disease, has identified more than 200 new genes that predispose individuals to this condition, for which no treatment currently exists. ...

Researchers from The George Institute for Global Health India, in partnership with the Chhanv Foundation, have examined the lived realities of acid attack survivors in India, focusing on the stigma they ...

Imagine walking into tall grass or working barefoot in a field … and suddenly feeling sharp pain on your foot. You've just been bitten by a snake. This is more than a moment of shock; it could be the ...

A new study by researchers at King's College London has split schizophrenia risk into two genetically distinct pathways. One is characterized by a shared genetic risk with bipolar disorder and associated ...

In an international study, researchers at Lund University in Sweden have identified a gene variant that controls the body's capability to form new blood vessels in muscles—a mechanism that affects physical ...

Exposure to lead before birth is associated with lower performance 60 years later on tests of thinking and memory skills in female participants, according to a study published in Neurology. The study ...

In a new study from Karolinska Institutet, published in Nature Neuroscience, researchers have identified the neurogenic progenitor that gives rise to dopaminergic neurons, the primary neurons affected ...

Sensitive hearing may have evolved in mammal ancestors far earlier than scientists once believed. By modeling how sound moved through the skull of Thrinaxodon, a 250-million-year-old mammal predecessor, researchers found it likely used an early eardrum to…

Genetic modification of viruses has long been used as a strategy to treat and prevent different types of diseases. Specifically, it consists of exploiting certain characteristics of viruses that make ...

If you have peanut butter at home, federal health officials say it's worth taking a closer look. The U.S. Food and Drug Administration (FDA) has announced a recall of more than 20,000 peanut butter products ...

Severely injured patients are more likely to survive if they are initially treated by an emergency medical services (EMS) clinician who sees a high number of trauma patients, rather than a clinician in ...

Researchers from RCSI University of Medicine and Health Sciences have developed a novel implant that delivers tiny growth-promoting particles directly to injured nerve cells, helping them to regrow after ...

Whether you practice ballet or prefer the tango, the benefits of dancing are self-evident. It's good exercise both physically and mentally due to the complexity of the movements, and it's also a fun social ...

A team led by Northwestern University and Shirley Ryan AbilityLab scientists have developed a new technology that can eavesdrop on the hidden electrical dialogues unfolding inside miniature, lab-grown ...

Four-fifths of England's integrated care boards (ICBs)—responsible for planning health services for their local population—would need to at least double their number of general practitioners to meet ...

As new infectious threats emerge worldwide, a key U.S. health agency is quietly stepping away from language tied to pandemic planning, a change some experts warn could leave Americans less protected when ...

An EEG (electroencephalogram) is a painless test that uses small sensors placed on the scalp to measure the brain's electrical activity. It provides a real-time readout of brain "waves"—rhythms generated ...

Every day, the Ohio River sends billions of gallons of water flowing past Louisville's pumping station, where the Kentucky city's utility sucks it up to turn it into tap water.

Scientists have uncovered why people with chronic kidney disease so often die from heart problems: damaged kidneys release tiny particles into the bloodstream that actively poison the heart. These particles, produced only by diseased kidneys, carry genetic…
