(Institute for Operations Research and the Management Sciences) It's not uncommon for U.S. pharmaceutical companies to pay medical doctors to promote their medications. Questions over possible conflicts of interest have ...

Moore’s Law is faltering, but that doesn’t mean the end of progress in processing power. But rather than relying on semiconductor physics and silicon-fabrication technology, we need to turn to innovations in software...

Physicists set a new record by linking together a hot soup of 15 trillion atoms in a bizarre phenomenon called quantum entanglement.

Scientists have recently identified a small mitochondrial uncoupler, named BAM15, that decreases the body fat mass of mice without affecting food intake and muscle mass or increasing body temperature.

Researchers working in rural Kenya have identified the most productive breeding habitats for mosquitoes that spread a range of untreatable viruses. Their findings point to more effective health interventions that focus o...

Loss of estrogen has an effect on muscles and leads to a decline in muscle mass. Physical activity in all of its forms may help maintain muscle mass in midlife.

Scientists have shown that pancreatic cancer metastasis -- when tumor cells gain the deadly ability to migrate to new parts of the body -- can be suppressed by inhibiting a protein called Slug that regulates cell movemen...

Virus DNA left on a hospital bed rail was found in nearly half of all sites sampled across a ward within 10 hours and persisted for at least five days, according to a new study in the United Kingdom.

Taking prescription blood pressure medication helped even the frailest elderly patients live longer, according to a large study in Italy. While the improved survival benefit was found in all older people, the healthier o...

Great white sharks are fierce hunters. But as juveniles, their diets involve way more bottom-feeding than hunting large prey.

The trick, apparently, was to hang the toad upside down in a chimney for three days.

New evidence confirms COVID-19 infection is the cause of the Kawasaki-like syndrome affecting children.

AI network simulations become unstable following continuous periods of unsupervised learning. When the networks were exposed to states that are analogous to human brain waves during sleep, the stability was restored.

It's not often in nuclear physics that you can clearly get both sides of the story, but a recent experiment allowed researchers to do just that. They compared very similar nuclei to each other to get a clearer view of ho...

A team of Brown University physicists has developed a new type of compact, ultra-sensitive magnetometer. The new device could be useful in a variety of applications involving weak magnetic fields, the researchers say.

Making two different changes to a single messenger protein, researchers were able to inhibit lung cancer growth and promote neurogenesis.

Glial cells known as tanycytes deliver signals to neurons in the brain to activate appetite. Optogenetic stimulation of tanycytes increases appetite.

Study addresses the question of whether a forgotten memory is entirely lost or if it just becomes fuzzier over time.

Oxygen is highly reactive. It accumulates on many surfaces and determines their chemical behavior. At the Vienna University of Technology, scientists study the interaction between oxygen and metal oxide surfaces, which p...

Combatting the COVID-19 pandemic has become an international challenge and charge. It has highlighted the positive consequences of science operating on a global scale. It has shown how answers can be found quickly when s...

Attorney General Bill Bar sought to downplay the clearing of peaceful protestors from Lafayette Park in Washington, D.C. on June 1 by claiming that pepper spray is not a chemical or an irritant. It is and here's the scie...

Rattlesnakes are threatened in British Columbia in Canada, and many populations are declining at alarming rates.
