How animal identifiability affects children's food choices‎

Naming a chicken and describing its favorite habits is enough to make preschoolers choose poultry less often. This effect translates into verbal declarations and actual meal choices, but food preferences still most often win over empathy, according to a new paper by researchers from SWPS University.

Political violence: How justifications influence voter approval‎

What happens when political violence is presented as a justified response to threat or injustice coming from an out-group? A study by Ursula Daxecker, director at the Max Planck Institute for Politics and Social Science in Göttingen, and Neeraj Prasad of the University of Amsterdam, published in The Journal of Politics, finds that legitimizing violence can increase public approval of both violence and the parties involved in it. Among BJP supporters, the effect went even further: when violence was portrayed as justified, they were less approving of a peaceful response by their own party.

Scientists uncover mystery of how snail shells coil to the right or to the left‎

Scientists have discovered a gene that determines whether Japanese snails develop shells that are left- or right-coiling—with implications for understanding the underlying handedness of our own bodies. The researchers from the University of Nottingham and Tohoku University studied wild Euhadra snails in Japan to understand what makes one snail a mirror image of another.

Rabbits were a medieval royal luxury in England—until the Black Death made them commonplace‎

The European rabbit is a common sight in the British countryside today. Yet it was not always so. They are not native to the British Isles and are one of the most devastating invasive species.

Astronomer leads global team on NASA mission to create unprecedented view of the early universe‎

A University of Missouri astronomer is leading a team of 130 researchers from 62 institutions—including NASA, the California Institute of Technology, Princeton University and Harvard University—on an ambitious mission to capture an unprecedented view of the early universe.

Plants shift gene activity within minutes of entering spaceflight, experiment reveals‎

Plants begin responding to spaceflight almost immediately after leaving Earth, according to a new University of Florida study that captured the earliest stages of biological adaptation during a commercial suborbital mission. Published in the journal npj Microgravity, the study reports the results of an experiment conducted by a UF astronaut during Blue Origin's New Shepard NS-26 flight on Aug. 29, 2024.

New 3D model reveals how shadows reshape chemistry in stellar nurseries‎

How do young stars reshape the clouds from which they are born? A new high-resolution 3D model developed by an international team led by Dr Brandt Gaches from the University of Duisburg-Essen shows how the uneven structure of stellar nurseries creates shadows that alter their chemistry and influence the infrared emission observed by the James Webb Space Telescope. The model has now been published in Astronomy & Astrophysics.

Scientists discover cell division does more than make new cells: It helps reshape tissues‎

Every time a tissue grows or renews itself, cells must divide inside an already crowded environment. That creates a fundamental problem that scientists have not fully understood: How does a tightly packed sheet of cells make room for two daughter cells when there was once only one?

New high-frequency method boosts 2D material readout for next-gen quantum computers‎

Quantum computers represent a next step in the fast-paced evolution of technology. Using quantum bits (qubits), they have the potential to run certain calculations exponentially faster than conventional computers. However, developing and fine-tuning quantum computers requires an enormous number of repetitive tests. To accelerate quantum technology development, we need a method that can read quantum states at ultrafast speeds.
