Through questioning their assumptions about how mosquitoes sense and interpret odors, scientists may have discovered why efforts to throw the vectors of dengue and Zika off the human scent have not succeeded.
If COVID-19 lockdowns scrambled your sleep schedule and stretched your waistline, you're not alone. Fruit flies quarantined in test tubes sleep too little and eat too much after only one week of social isolation.
Our brains have sensory cells, which process the faces that we see, and memory cells dedicated to storing data from person encounters. But until now, a hybrid neuron capable of linking vision to memory—and explaining how we recall familiar faces—remained elusive.
Scientists have launched an ambitious effort to produce high-quality reference genomes for all vertebrate species, from mammals to birds and reptiles. The result could be discoveries with implications for animal conservation as well as human health and disease.
COVID-19 causes a host of diverse complications, from lung inflammation to blood clots, heart failure, and brain fog. A team of scientists believes these attributes may have a single culprit—and that findings from research on Alzheimer’s disease might give them a leg up in finding it.
Unlike most humans, bats are naturally resistant to coronavirus infection. Researchers are now searching their genomes for clues that might explain why SARS-CoV-2 can cause devastating disease in our own species.
Female mosquitoes are armed with syringe-like stylets that begin to pump furiously only in the presence of blood. Scientists are now studying the specific neurons that line the stylet, and asking what mosquitoes taste when they bite us.
Rice will receive the 2020 Nobel Prize in Physiology or Medicine for research that led to a cure for hepatitis C, a viral disease affecting 170 million people worldwide. His lab worked on the virus for three decades and became the first to produce a version of it that could be grown and studied i...
Scientists have outlined a molecular program by which serotonin reuptake inhibitors reshape the brain to alleviate depression. Their findings provide clues for how to make better and faster-acting versions of these drugs.
Scientists have found that a hormone tells the brain to dramatically restructure neurons embedded in fat tissue. Their work widens our understanding of how the body regulates its energy consumption, and how obesity might be treated in the future.
How do primitive cells “know” where to go during development? Scientists studying the fish equivalent of inner-ear hair cells have shown that biochemical and mechanical cues work together to orchestrate a highly complex arrangement.
Researchers have identified a set of biological factors in mice that seem to determine one's ability to bounce back from a traumatic event, and provide preliminary evidence that a naturally-occurring substance may help boost resiliency in the face of stressful situations.
Protein clumps are routinely found in the brains of patients with neurodegenerative diseases. Now researchers find a link between this buildup and the intracellular movement of proteasomes, molecular machines tasked with degrading protein waste inside cells.
A new study finds that neurons affected in Parkinson’s disease can shut down without fully dying, allowing them to also switch off neighboring cells. The findings might give scientists a better understanding of how the condition wreaks havoc in the brain, as well as ideas for new treatments.
Scientists have found that many receptors with high potential for drug discovery take a different configuration inside the body than in the test tube. The findings could explain why some promising drugs fail in clinical trials, and potentially open doors to new drug-development approaches.
Ruta, who investigates how the brain is modified by experience, has received a MacArthur Fellowship, an award intended to encourage people of outstanding talent to pursue their own creative, intellectual, and professional inclinations.
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.
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.
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.
Scientists have discovered a curious phenomenon taking place in mouse skin: cells compete with one another for the chance to develop into mature tissue. The findings indicate that this antagonism is key to creating healthy skin.
Rockefeller scientists have identified a genetic condition that makes people prone to developing tuberculosis. In a British population, they found that the condition underlies one percent of cases of the disease—a finding that may ultimately lead to new treatment options.
New research on leptin, a hormone that regulates appetite, reveals a previously unknown mechanism that may be responsible for at least 10 percent of obesity cases. The findings could help identify individuals with treatable forms of the condition.
When looking for food, the roundworm C. elegans searches the same area for up to 20 minutes before trying its luck at more distant locales. New research on the worm’s brain explains how this behavior arises at the level of molecules and cells.
Scientists have learned new tricks that could be useful in preventing mosquito-borne illnesses such as Zika and yellow fever. A new study shows that some appetite-reducing drugs can curtail the insects’ impulse to feed on warm-blooded hosts.
By analyzing gene expression patterns, researchers have identified previously unknown distinctions between mouse and human neurons. They have also developed a new way to track cellular changes associated with brain disorders.
Researchers have assembled a new and improved DNA catalogue for the mosquito Aedes aegypti. This tool will help researchers understand the insect’s biology, and may lead to new strategies for preventing diseases like Zika and dengue.
A new study illuminates the biology that guides behavior across different stages of life in worms, and suggests how variations in specific neuromodulators in the developing nervous system may lead to occasional variations.
Scientists have discovered a group of brain cells that may play a role in keeping smokers addicted to nicotine. Their work could ultimately lead to new drugs to help people conquer their tobacco dependence.
A protein transferred from male to female mosquitoes during sex influences female mating behavior—a phenomenon that could be exploited to limit the spread of mosquito-borne illnesses like Zika and dengue.
Researchers have found that the cells directing the very first steps of brain formation are not other neurons, as scientists have long assumed. They've also uncovered previously hidden molecular pathways that attract neurons into the brain.
Scientists found that inhibiting a regulatory protein alters the intricate signaling chemistry that is responsible for many of the disease’s symptoms. The findings provide a path to possible therapeutics for disorders associated with Fragile X.
