Inflammation has to fight pathogens fast—but it can't get out of control. Researchers at the German Cancer Research Center (DKFZ) have now deciphered in more detail how the organism masters this balancing act. Their work shows that cells use two different strategies to
Chirality—often described as "handedness"—is a fundamental property of nature, underlying the behavior of molecules ranging from DNA to pharmaceuticals. While chemists have long known how to separate left- and right-handed forms of organic compounds, achieving the same control
New research has found that roughly half of Australia's freshwater fish are fond of snacking on animal and plant material, including fruits, from outside their aquatic habitats.

Seismic tremors reveal a shallow fragment of an ancient tectonic plate beneath Northern California, helping explain damaging earthquakes near the surface.
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and start eliminating the pathogen. T cells are extremely
Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals across whole communities and within individual plants.
Volunteers consider it relatively unacceptable to cancel social plans – but they are more forgiving if it's someone else cancelling the plans
Scientists have discovered there is more to Antarctica than meets the eye. A new map of the landscape beneath the frozen continent's ice sheet has revealed a previously hidden world of mountains, deep canyons and rugged hills in unprecedented detail.
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Once the world's most populous nation, China is now among the many Asian countries struggling with anemic fertility rates. In an attempt to double the country's rate of 1.0 children per woman, Beijing is reaching for a new tool: taxes on condoms, birth control pills and other
Oceans shape everyday life in powerful ways. They cover 70% of the planet, carry 90% of global trade, and support millions of jobs and the diets of billions of people. As global competition intensifies and climate change accelerates, the world's oceans are also becoming the
Whales, dolphins and other marine mammals are highly social, but those social ties can also help diseases spread through populations of rare or threatened species.
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating essential cognitive functions like wakefulness,
Solve the math puzzle from our February 2026 issue, where we plan a return passage for a robotic explorer that doesn’t want to explore.

A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the journal Science.
A missed birthday. A forgotten anniversary. A milestone that goes unnoticed. These small slights from a manager may seem like no big deal, but new research from Wharton reveals that even the mildest of mistreatment at work can affect more than just employee morale.
A new framework for understanding the nonmonotonic temperature dependence and sign reversal of the chirality-related anomalous Hall effect in highly conductive metals has been developed by scientists at Science Tokyo. This framework provides a clear picture of the unusual
The phenomenon where electron spins align in a specific direction after passing through chiral materials is a cornerstone for future spin-based electronics. Yet, the precise process behind this effect has remained a mystery—until now.
An international team of astronomers, including researchers from the Department of Physics at The University of Hong Kong (HKU), has uncovered the first decisive evidence that at least some fast radio burst (FRB) sources—brief but powerful flashes of radio waves from distant
Wildflower expert Naomi Fraga was excited about the prospect of an extraordinary bloom this spring, after a winter of near record rainfall, but this week's unseasonably hot, dry weather has dimmed her hopes for a superbloom year.
