Desert locusts typically lead solitary lives until something—like intense rainfall—triggers them to swarm in vast numbers, often with devastating consequences.

Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune respo

If all the world's a stage and all the species merely players, then their exits and entrances can be found in the rock record. Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a Vi

La Brea Tar Pits scientists have identified a previously unknown juniper species as Juniperus scopulorum, commonly known as the Rocky Mountain Juniper. The successful identification, along with the first-ever radiocarbon dating of these fossil plants in S

At one time or another, most of us have played with a flipbook, using our thumbs to rapidly flip a series of pictures to create an illusion of movement.

A concentrated sugar solution could be just as effective as antibiotics at treating a common infection in dairy cows, according to a new study led by researchers at Penn State. The results were recently published in the journal Frontiers in Veterinary Sci

Within minutes of fertilization, the egg of a fruit fly becomes a scene from the battle of the sexes. The egg attacks and destroys the cellular "power plants" (mitochondria) from the sperm that had fertilized it, so that only its own mitochondri

Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators—and new research led by Penn State scientists suggests they are increasingly at risk due to rising global temperatures.

Researchers at TU Delft have discovered that E. coli bacteria can synchronize their movements, creating order in seemingly random biological systems. By trapping individual bacteria in micro-engineered circular cavities and coupling these cavities through

Controlling matter at the atomic level has taken a major step forward, thanks to nanotechnology research by an international team of scientists led by physicists at the University of Bath.

Semiconducting transition metal dichalcogenides (TMDs) are a class of layered materials exhibiting unique optoelectronic properties that could be leveraged to develop transistors, sensors and other nanoelectronics. Despite their advantages, creating robus

In the ongoing battle against cancer, early detection remains a crucial factor in improving survival rates and reducing the economic burden on health care systems.
