The science & discovery headlines that matter, in one email every morning. Free.
Mountains preserve evidence of ancient oceans, moving continents and tectonic processes that have shaped Earth over millions of years. Later deformation, erosion and burial, however, can obscure important parts of this geological record. An international research team led by Ista
Every black hole hides a question at its center. Einstein's theory predicts that whatever falls in is crushed into a singularity, a point of infinite density where the theory itself breaks down. Most physicists expect quantum gravity to replace that point with something finite. B
NASA has taken the next step in the process of developing a new all-glass telescope for the LISA (Laser Interferometer Space Antenna) mission, a space observatory designed to detect ripples in space-time called gravitational waves.
The fact that ecosystems change is nothing new. What is new, however, is the speed and scale at which new species communities are emerging as a result of climate change. Processes that once unfolded over centuries or even millennia are now being observed within just a few decades
Cornell researchers have designed a new, faster form of two-photon fluorescence imaging for observing cell metabolism in real time, a method that could enable quicker screening of new therapeutic treatments. The findings were published Sept. 4 in Science Advances. The co-lead aut
A new study of 4,200 adolescents revealed that cyberbullying rarely occurs in isolation; it almost always functions as an extension of physical and verbal aggression already present in the school environment. The study, conducted at the Federal University of São Paulo (Unifesp) i
Genetic analysis revealed that several seeds from a batch sold as Sidra were not, in fact, Sidra; their genetic profile was closer to that of Batian, a Kenyan variety.
A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone expected. Using the James Webb Space Telescope, Brittany Miles, assistant astronomer at the University of Arizona's Steward Observatory, led a team that spe
Scientists have created a new family of materials whose behavior can be tuned by changing their metallic "recipe"—opening new possibilities for uses including gas storage and sensing.
Finding a single cancer cell in a tube of blood is a bit like finding a needle in a haystack. As researchers seek to detect ever-smaller and rarer targets, from viruses to circulating tumor cells in blood, the demand for ultrasensitive, robust sensors that are practical for real-
When a dying star runs out of fuel and sheds its outer layers, its remaining core can become an approximately Earth-sized, extremely dense stellar remnant called a white dwarf. For a white dwarf that is not strongly rotating or magnetized, there is a well-known upper mass limit o
The threat of cyberattacks against American agriculture and food systems is growing, and Washington State University researchers are helping to lead a call for a national consortium of land-grant universities to study and combat the threat.
Seventy-three years ago, Tenzing Norgay stood on top of Everest, known as Chomolungma in Tibetan, which roughly translates as "Goddess Mother of the World."

Per- and polyfluoroalkyl substances (PFAS)—a vast family of chemicals used largely for their nonstick, water-repellent and grease-resistant properties—are called "forever chemicals" because of their remarkable resistance to degradation. They are now ubiquitous in our environment.
Every black hole hides a question at its center. Einstein's theory predicts that whatever falls in is crushed into a singularity, a point of infinite density where the theory itself breaks down. Most physicists expect quantum gravity to replace that point with something finite. B
Drought is written into trees, appearing as narrow bands in their annual growth rings. But aspen may go farther, creating "functional memories" of previous dry years reflected in the chemistry of their leaves, according to new research by University of Utah biologists.

A new study led by Paul Schulze-Lefert from the Max Planck Institute for Plant Breeding Research in Cologne, in collaboration with Ricardo F.H. Giehl at the Leibniz Institute of Plant Genetics and Crop Plant Research in Gatersleben, revealed how Arabidopsis plants adapt their che
A novel nanovesicle-based platform developed at Institute of Science Tokyo can measure hydrostatic pressure by converting pressure-induced molecular changes into fluorescence signals.

Polar oceans may play an important role in storing carbon and supporting biodiversity, but current science and policy frameworks are not yet ready to fully recognize their potential.
