Capsule technology opens new window into individual cells

Researchers have developed a capsule-based method that makes it possible to analyze the same cell through multiple experimental steps. The technology overcomes a long-standing limitation in cell research and could open new ways to study disease mechanisms at the single-cell

NASA's tiny spacecraft sends first exoplanet images

With the first images from the spacecraft now in hand, the team behind NASA's Star-Planet Activity Research CubeSat, or SPARCS, is ready to begin charting the energetic lives of the galaxy's most common stars to help answer one of humanity's most profound questions: Which

Wolves kill—and ravens remember where

When a wolf pack runs down its prey, the first on the scene is often the raven. Even before the predators have had time to dig in, the ravens are already in line, waiting to take advantage of the odd scrap of meat that becomes available. The speed with which the scavengers

Wood surface treatment fights harmful bacteria

A University of Helsinki study has investigated bacterial adhesion, survival and transmission on untreated and treated wood surfaces under both laboratory and field conditions. The laboratory work focused on Staphylococcus epidermidis, a bacterium that forms part of the skin's

Gen Z holds companies to account for greenwashing

Companies increasingly want to talk about sustainability, but not everyone believes equally in their commitments. The focus of corporate communication has shifted towards sustainability in response to increasingly serious environmental issues, international campaigns such as

A familiar voice shapes how zebra finches hear and respond

Conversations with friends have an ease that is hard to replicate with someone you have just met—often replies come more naturally and timing just seems to click. A strikingly similar pattern plays out in zebra finches, very sociable songbirds whose back-and-forth chatter with

'Ionic liquids' could redefine the habitable zone

"Follow the water" has been a guiding mantra of astrobiology, and even space exploration more generally, for decades. If you want to find life, it makes sense to look for the universal solvent that almost all types of life on Earth use. But what if life doesn't actually need

Tiny marine organism stressed by warmer Arctic waters

Some of the smallest marine species are actually the most important because all other life depends on them. Phytoplankton are probably the most important, but just above them in the food chain are zooplankton. In Norway's cold Atlantic waters, the zooplankton in question is

Astronomers discuss fortifying our planetary defenses

When people think of asteroids, they tend to picture rare, civilization-ending impacts like those depicted in movies such as "Armageddon." In reality, the asteroids most likely to affect modern society are much smaller. While kilometer-scale impacts occur only every tens of

Wetlands in Brazil's Cerrado are carbon-storage powerhouses

The Amazon rainforest is famous for storing massive amounts of carbon in its trees and soils, helping regulate the global climate. Yet a paper published in New Phytologist shows that one of South America's largest carbon-storing ecosystems exists in an often-overlooked grassy

Gut microbes: The secret to squirrel hibernation

When winter sets in and food becomes scarce, some mammals hibernate, entering a state of deep rest that slashes their energy needs and allows them to fast for months. However, fasting deprives them of essential nutrients, including carbon. Carbon, the building block of all

Selfish sperm hijack Overdrive gene to kill healthy rivals

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery—how "selfish chromosomes" cheat the rules of genetic inheritance. The researchers found that rogue chromosomes hijack the Overdrive (Ovd) gene to destroy rival sperm.
