Do hyenas eat livestock and rhinos? Behavioral biologists investigate a surprisingly charm

For conservation and the management of human–wildlife conflicts, it is of great interest to know which species are eaten by carnivores. Scientists from the Ngorongoro Hyena Project at the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) analyzed this dynamic for spot

Natural hallucinogens may have evolved as ecological tools, not chemical accidents

Natural hallucinogens, such as psilocybin, mescaline, N,N-dimethyltryptamine (DMT) and related compounds, have generally received attention for their effects on human perception, emotion and cognition. Recently, interest in these compounds has expanded to include their potential

Oxygen atoms in 15‑million‑year‑old giant eggshells reveal how plants reacted to a hotter

Some periods in Earth's history are so different from our own that they may as well belong to another planet. Many people are interested in the age of dinosaurs or the Ice Ages, but it is an intermediate world, the Miocene Epoch—a sort of "in-between" world, geologically speaking

Loss of DNA protector gene exposes vulnerabilities in cancerous cells

Every time a cell copies its DNA, parts of the genome are exposed and vulnerable to damage or errors. Molecular biologist Simon Boulton is interested in how cells spot and repair damage to their DNA, and what happens if this process fails or if key genes are mutated.

Astronomers characterize 'improbable' system shaped by brown dwarf

In the course of studying planets beyond our solar system (6,316 confirmed exoplanets and counting), scientists have discovered some very interesting systems. Consider TOI-201, a compact system populated by three bodies, including a brown dwarf, orbiting on the same plane. The sy

How an interstellar comet sheds light on universe's 'cosmic noon'

Last year, an interstellar traveler entered our solar system. Some speculated that it was an alien spacecraft, but it turned out to be a comet, 3I/Atlas, and it provoked interest from astronomers and astrophysicists eager for insights into galaxies far, far away. Detailed observa
