Science, engineering, and discovery — the research and breakthroughs that matter.

A rare CO chondrite meteorite was the probable impacter that struck Earth 66 million years ago, wiping out 75% of Earth's species, including nonavian dinosaurs. These findings are published in Science Advances. Researchers at the University of British Columbia (UBC), Paris, Bruss

Framing environmental risks in terms of how much time is left, rather than a future date, makes them feel more urgent and increases public engagement.

Long before dinosaurs ruled the continents and modern crocodiles first appeared, their ancestors were already going through a decisive phase in their evolutionary history. It was in this ancient world, shortly after the greatest mass extinction in Earth's history, that a new spec

Researchers at Uppsala University have calculated that the sun contains 55% more silver than previously estimated. The results are based on more realistic modeling of the sun's atmosphere and resolve a long-standing problem of missing silver in the solar system.

As sea levels rise due to climate change, encroaching seawater will likely make freshwater environments saltier. In a new study, MIT researchers have shown how that increase in salinity might affect microbial ecosystems found in environments such as rivers and estuaries.

Dropping standardized testing requirements may make college admission more accessible for some, but it can also make it harder for universities to identify high-potential students, according to new research published in Management Science. The research suggests the decision invol

PathSay Project uses AI to cross language barriers and more — today's student signal.

Thousands of the world's languages remain largely invisible to modern translation technology, but researchers and students at Brigham Young University are working to change that. Through a project called Pathsay, students in the BYU MATRIX lab are partnering with international BY

In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear fission marks an important step toward a better understan

A new analysis from the University of Illinois Urbana-Champaign and the Illinois Soybean Association finds that Illinois corn and soybean farmers could lose up to $609 million per year—representing a 3.6% revenue loss—if the state banned the weedkiller glyphosate. The study is pu

In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star. The finding provides the strongest evidence yet that worlds with

For more than 25 years, lab-on-a-chip technology has allowed researchers to model human organs and blood vessels using real human cells in artificial microscopic environments. These microphysiological systems (MPS) may replicate human cells and mimic organs or even full organ sys

A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become increasingly structured and complex while still obeying the second law of thermodynam

Seoul National University College of Engineering announced that a joint research team led by Professor Namkyoo Park and Professor Sunkyu Yu of the Department of Electrical and Computer Engineering at SNU, in collaboration with Professor Xianji Piao of the School of Electrical and

Deep beneath the French-Swiss border, the world's largest scientific instrument has fallen silent. After years of smashing protons together at nearly the speed of light, CERN's Large Hadron Collider (LHC) has stopped operations and entered a long shutdown.

A new review in Limnology and Oceanography led by scientists at UC San Diego's Scripps Institution of Oceanography warns that the rapid loss of oxygen from the ocean and other aquatic ecosystems is pushing Earth toward an "unsafe space," with consequences that could be irreversib

Just as careful blending of eye shadow can make a difference to our looks, a recent study has shown how flowers go to considerable trouble to fine-tune their shades. In the relentless competition to attract bees, a slight edge can make the difference between life and death for a

Alberto Borges, oceanographer at the University of Liège, has conducted a comparative study in Belgium and Africa on the microbial oxidation of methane in rivers, a natural process in which certain bacteria consume this powerful greenhouse gas before it is released into the atmos

Dense wildfire smoke billowing down from Canada set off unhealthy air quality alerts across the United States again on Friday, stirring concern over the weekend's World Cup final outside New York.

How do wildfires grow into catastrophic events? By tracing the earliest detectable origins of the devastating 2015 equatorial Southeast Asian fires, researchers found that most large fires had multiple origin points and identified the ecological, climatic and human factors associ

Researchers in Thailand have developed a prototype high-performance bicycle tire that replaces conventional nylon fabric reinforcement with natural silk. The team combined laboratory-scale material testing with pilot-scale tire manufacturing. Natural rubber composites were produc

Cells are like metropolises, home to millions of molecular residents. If one were to stand atop a high-rise, trying to identify most of its inhabitants would seem an impossible task. Even with the sophisticated imaging tools currently available to scientists, it is challenging to
