These bacteria perform a trick that could keep plants healthy

To stay healthy, plants balance the energy they put into growing with the amount they use to defend against harmful bacteria. The mechanisms behind this equilibrium have largely remained mysterious. Now, engineers at Princeton have found an answer in an unexpected place: the harmless, or sometimes beneficial, bacteria that cluster around plants’ roots. In an article published Dec. 24 in the journal Cell Reports, researchers showed that some types of soil bacteria can influence a plant’s ...

Detecting disease with only a single molecule

UC Riverside scientists have developed a nanopore-based tool that could help diagnose illnesses much faster and with greater precision than current tests allow, by capturing signals from individual molecules.  Since the molecules scientists want to detect -- generally certain DNA or protein molecules -- are roughly one-billionth of a meter wide, the electrical signals they produce are very small and require specialized detection instruments.  “Right now, you need millions of molecules to detect ...

Newborn brain circuit stabilizes gaze

An ancient brain circuit, which enables the eyes to reflexively rotate up as the body tilts down, tunes itself early in life as an animal develops, a new study finds.  Led by researchers at NYU Grossman School of Medicine, the study revolves around how vertebrates, which includes humans and animals spanning evolution from primitive fish to mammals, stabilize their gaze as they move. To do so they use a brain circuit that turns any shifts in orientation sensed by the balance (vestibular) system in their ears into an instant counter-movement by their eyes. Called ...

Bats surf storm fronts during continental migration

Birds are the undisputed champions of epic travel—but they are not the only long-haul fliers. A handful of bats are known to travel thousands of kilometers in continental migrations across North America, Europe, and Africa. The behavior is rare and difficult to observe, which is why long-distance bat migration has remained an enigma. Now, scientists from the Max Planck Institute of Animal Behavior (MPI-AB) have studied 71 common noctule bats on their spring migration across the European continent, providing a leap in understanding this mysterious behavior. Ultra-lightweight, intelligent sensors attached ...

Secrets of migratory bats: They “surf” storm front winds to save energy

A species of migrating bat “surfs” the warm winds of incoming storm fronts to conserve energy, according to a study that used tags to track the tiny animals on their long journeys across central Europe. The findings offer new insights into how weather, physiology, and environmental factors shape bats’ seasonal migration patterns. While bird migration is well-documented and studied, this is not the case for seasonal migration of bats – particularly the few long-distance, migratory species. These nocturnal travelers face substantial challenges, ...

Early life “luck” among competitive male mice leads to competitive advantage overall

Early life "luck" plays a pivotal role in shaping individuality and success, particularly for males, according to a new study in mice. In male animals, competitive social dynamics amplified small initial differences into lifelong disparities in fitness. The findings highlight parallels between biological competition and societal inequalities and they demonstrate how chance events can drive divergent outcomes even among genetically identical individuals. Contingency (colloquially, “luck”) refers to the role of chance in shaping outcomes. It is a critical factor in both biological and social sciences, ...

Genetics of alternating sexes in walnuts

The genetics behind the alternating sexes of walnut trees has been revealed by biologists at the University of California, Davis. The research, published Jan. 3 in Science, reveals a mechanism that has been stable in walnuts and their ancestors going back 40 million years — and which has some parallels to sex determination in humans and other animals.  Flowering plants have many ways to avoid pollinating themselves. Some do this by structuring flowers to make self-pollination difficult; some species have separate “male” and “female” plants. ...

What happens when some cells are more like Dad than Mom

NEW YORK, NY--New work by Columbia researchers has turned a textbook principle of genetics on its head and revealed why some people who carry disease-causing genes experience no symptoms. Every biology student learns that each cell in our body (except sperm and eggs) contains two copies of each gene, one from each parent, and each copy plays an equal part in the cell.  The new study shows that some cells are often biased when it comes to some genes and inactivate one parent’s copy. The phenomenon was discovered about a decade ago, but ...
