Ant colonies behave like neural networks when making decisions 

Colonies decide to flee rising temperatures in much the same way that neural computations give rise to decisions.

How a fly's brain calculates its position in space

New research reveals how neurons in a fly's brain signal the direction in which the body is traveling. The cells appear to literally perform vector math in order to act as a biological compass.

Study detects origins of Huntington's disease in two-week-old human embryos

The findings shed new light on the root causes of this disease, which leads to the degeneration of neurons in midlife.

The physics behind a water bear's lumbering gait

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.

When ant colonies get bigger, new foraging behavior emerges

By increasing the size of ant colonies bit by bit, scientists identified the mechanism responsible for the evolution of mass raiding behavior.

New findings to boost IVF success rates

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 release error-free genomes of 25 animals—with another 70,000 coming up

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.

A case for simplifying gene nomenclature across different organisms

Scientists call it oxytocin in humans, isotocin in fish, mesotocin in birds, and valitocin in sharks. But according to a new study, it’s all the same hormone—and high time we settled on just one name.


Financial crashes, pandemics, Texas snow: How math could predict "black swan" events

Statistical modeling may one day help scientists anticipate and manage a wide range of extreme occurrences, according to a new study.

Synthetic “micro lungs” could take COVID-19 research to the next level

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.

What bats can teach us about COVID-19

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.

Study gives clues to the origin of Huntington’s disease, and a new way to find drugs

Using a new technique to study brain development, scientists were able to trace the causes of Huntington's back to early developmental stages when the brain has only just begun to form.

From the tiny testes of flies, new insight into how genes arise

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.

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.

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.

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.

Embryos remember the chemicals that they encounter

A new study shows that embryonic cells retain a memory of the chemical signals to which they are exposed. Without these memories, cells fail organize into distinct tissue types.

In brief: Mutation explains why some people are more vulnerable to viral brain infection

Scientists identified mutations in a single gene that impair immunity to viruses in a region of the brain called the brain stem.

Uncovering the early origins of Huntington’s disease

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.

Researchers have uncovered the neurons that spin a fly’s internal compass when the insect turns—the first such mechanism identified in any animal.

New research explains why a common bacterium can produce severe illness

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...

New findings challenge popular explanation for why a social insect becomes a worker or queen

The exquisite social hierarchy of insect colonies has long fascinated scientists. Take two eggs—both contain identical genetic material, but while one becomes a sterile worker, the other may develop into a queen that can reproduce. Workers perform brood care and other crucial tasks that keep the ...

Researchers develop gene-filtering tool to identify disease-causing mutations

Despite their bad reputations, the vast majority of mutations are not harmful. Even in very rare genetic disorders, only one or two genetic variations ­— out of tens of thousands — is actually the cause of disease. Distinguishing between harmful and harmless mutations has long been a challenge....

New research explores how the fly brain reroutes odor information to produce flexible behavior

Some responses come automatically, like reflexes. Others vary with circumstance and experience. A once-delicious smell can be easily overlooked during a stressful moment or when it calls to mind a bout of food poisoning, for instance. This happens because, within the brain, molecules known as neu...
