Exploring genetic “dark matter,” researchers gain new insights into autism and stroke
For the brain to function smoothly, its cells must carefully regulate which proteins are produced and when. By studying gene regulation, researchers are now shedding light on complex brain conditions like autism and stroke.
Fruit flies find their way by setting navigational goals
Navigating fruit flies do not have the luxury of GPS, but they do have a kind of neural compass. In a new study, researchers found that the animals decide which way to turn by comparing this internal compass needle to a fixed goal.
Hinge-like protein may open new doors in cystic fibrosis treatment
Drugs known as potentiators alleviate some symptoms of cystic fibrosis. Researchers recently figured out how these compounds work—a finding that may lead to better drugs that patients can more easily afford.
Three-dimensional model illuminates key aspects of early development
Researchers have created a new 3D model of human embryonic tissue that promises to shed light on critical components of development—including processes that go awry during pregnancy complications.
New research raises prospect of better anti-obesity drugs
Scientists have found a group of brain cells that influence body mass in two ways, by controlling how much we eat as well as how much energy we burn. The findings could lead to new drugs to help people shed weight.
Learning from experience is all in the timing
Animals learn the hard way which sights, sounds, and smells are relevant to survival. New research in flies shows that the timing of these cues plays an important role in how mental associations arise, and elucidates brain pathways involved in this process.
New molecular diagnostics test could help guide lupus treatments
A tool that detects glitches in gene expression could help doctors tailor treatments for lupus-related kidney damage.
New research shows that mosquitoes sense repellent through their legs
Scientists made the surprising discovery that the insects’ displeasure for touching DEET, the active ingredient in many repellents, helps prevent bites.
To curb infection, bacteria direct their defenses against themselves
To fight off invading viruses, bacteria have evolved a slew of creative defense tactics. New research shows that in some cases, microbes go to great lengths to keep an infection from spreading, even destroying bits of their own genetic material.
New compounds could be used to treat autoimmune disorders
In autoimmune disorders, the body’s defense system erroneously attacks normal cells, leading to serious health problems. Researchers have developed new molecules that potentially could be used to treat many of these conditions.
