Animals as small and soft as tardigrades seldom have legs and almost never bother walking. But a new study finds that water bears propel themselves through sediment and soil on eight stubby legs, in a manner resembling that of insects 500,000 times their size.
New research casts doubt on a genetic test used to screen would-be embryos for IVF implantation. The findings suggests that these embryos can develop into healthy babies regardless of whether or not they’ve been flagged as defective by the test.
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.
Scientists have developed stem-cell technology to mass-produce tissue cultures resembling our breathing organs. These tissues offer a powerful model in which to study how SARS-CoV-2 wreaks havoc in the lungs and to screen for new drugs.
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.
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.
A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences—and a better understanding of how evolution moves forward.
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.
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.
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.
The symptoms of Huntington’s typically appear in middle age, but the disease may in fact originate much earlier. New research shows that a patient’s neural abnormalities may arise already during embryonic development—suggesting that treating the disease early may be beneficial.
As much as we try to avoid it, we are constantly sharing germs with those around us. But even when two people have the same infection, the resulting illnesses can be dramatically different—mild for one person, severe or even life-threatening for the other. Now, new research from The Rockefell...
