Scientists have engineered a mouse model to study a rare and often-fatal form of liver cancer. They’ve used it to clarify what drives these tumors at the molecular level, and discover new drug concepts.
Scientists have discovered a peculiarity in the genetic code of HIV that might explain how this and other viruses evolved ways to dodge our immune system. The findings could make it possible to develop safer vaccines.
Scientists have identified a protein that many viruses require to spread within a host—a discovery that could lead to fighting diseases as varied as parainfluenza, West Nile, and Zika with a single drug. This finding could also lead to the development of treatments for emerging viruses.
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.
Scientists have found that stem cells in the skin remember an injury, helping them close recurring wounds faster. The discovery could advance research and treatment of psoriasis and other inflammatory diseases.
Scientists have found unexpected differences in how male and female mice respond to stress. Their findings are raising big questions about sex discrepancies in the brain and their impact on neuropsychiatric disease.
Rockefeller University biologist Michael W. Young, who studies the biological clocks that regulate sleep, metabolism, and response to disease, is this year’s recipient of the Nobel Prize in Physiology or Medicine.
To keep up with evasive flu viruses, new vaccines must be developed each year. Scientists are devising a strategy to better prevent the disease without annual shots.
Scientists developed a method to genetically engineer gut bacteria to produce molecules that have the potential to treat certain disorders by altering human metabolism.
Scientists have located two areas in the brain that help us recognize familiar faces. The discovery will help them delve deeper into the relationship between face recognition, memory, and social knowledge.
Scientists disrupted a gene essential for sensing pheromones, resulting in severe deficiencies in the ants’ social behaviors and their ability to survive within a colony.
Within the oldest part of the brain, scientists have found cells in charge of controlling appetite and eating. The discovery could revitalize efforts to develop drugs for obesity that make us less hungry.
Neuroscientists have taken a major step toward answering longstanding questions about how Prozac and similar drugs act in the brain. Their findings could lead to better antidepressants that don't take weeks to kick in.
In the rats that roam New York City’s streets and tunnels, scientists have found a virus that resembles hepatitis C. They have used it to create the first animal model of the human disease, a breakthrough that potentially could yield a much-needed vaccine.
To learn more about dolphin cognition and communication, researchers have developed an underwater touchscreen using optical technology, the first of its kind.
By studying rhesus monkeys, researchers have identified a brain network dedicated to processing social interactions—a discovery that offers tantalizing clues to the origins of our ability to understand what other people are thinking.
When bacteria swim at just the right speed, swirling vortices emerge. As those patterns disintegrate into chaos, physicists detect a telling mathematical signature.
Scientists have long seen parallels between healing wounds and growing tumors. In studying the molecular changes that occur within both, a research team has discovered a new cancer-fuelling mechanism that potentially could inform drug development.
