Researchers discover the brain cells that make pain unpleasant

If you step on a tack, neurons in your brain will register two things: that there’s a piercing physical sensation in your foot, and that it’s not pleasant. A team of scientists at Stanford University has identified a bundle of... Continue Reading →

How mucus tames microbes

More than 200 square meters of our bodies -- including the digestive tract, lungs, and urinary tract -- are lined with mucus. In recent years, scientists have found some evidence that mucus is not just a physical barrier that traps... Continue Reading →

1-2 caffeinated drinks not linked with higher risk of migraines; 3+ may trigger them

Afflicting more than one billion adults worldwide, migraine is the third most prevalent illness in the world. In addition to severe headache, symptoms of migraine can include nausea, changes in mood, sensitivity to light and sound, as well as visual... Continue Reading →

Engineered viruses could fight drug resistance

In the battle against antibiotic resistance, many scientists have been trying to deploy naturally occurring viruses called bacteriophages that can infect and kill bacteria. Bacteriophages kill bacteria through different mechanisms than antibiotics, and they can target specific strains, making them... Continue Reading →

Aspirin may halve air pollution harms

A new study is the first to report evidence that nonsteroidal anti-inflammatory drugs (NSAIDs) like aspirin may lessen the adverse effects of air pollution exposure on lung function. The team of researchers from the Columbia Mailman School of Public Health,... Continue Reading →

Why is the brain disturbed by harsh sounds?

Why do the harsh sounds emitted by alarms or human shrieks grab our attention? What is going on in the brain when it detects these frequencies? Neuroscientists from the University of Geneva (UNIGE) and Geneva University Hospitals (HUG), Switzerland, have... Continue Reading →

Molecular basis of vision revealed

Researchers have solved the three-dimensional structure of a protein complex involved in vertebrate vision at atomic resolution, a finding that has broad implications for our understanding of biological signaling processes and the design of over a third of the drugs... Continue Reading →

2,000 Atoms Exist in Two Places at Once in Unprecedented Quantum Experiment

Giant molecules can be in two places at once, thanks to quantum physics. That's something that scientists have long known is theoretically true based on a few facts: Every particle or group of particles in the universe is also a wave... Continue Reading →
