Four Northwestern University astronomers are part of an international research collaboration that is the first to detect the spectacular collision of two neutron stars using both gravitational waves and light. The discovery ushers in an exciting new era in astronomy -- multi-messenger astronomy with gravitational waves -- less than two years after the first detection of gravitational waves opened a new window onto the universe. The astronomers hold leading roles on both sides of discovery, in gravitational-wave astronomy and electromagnetic astronomy.

Carbon dioxide measured by a NASA satellite pinpoints sources of the gas from human and volcanic activities, which may help monitor greenhouse gases responsible for climate change.

Financial losses could increase by more than 70 percent by 2100 if oceans warm at the worst-case-scenario rate predicted by the Intergovernmental Panel on Climate Change, according to a new study. The study used hurricane modeling and information in FEMA's HAZUS database to reach its conclusions.

Researchers at Penn State College of Medicine and Cold Spring Harbor Laboratory have reported the first-ever quantitative whole-brain map of inhibitory neurons in the mouse brain.

Researchers have shown, for the first time, that reduced dietary potassium promotes elevated aortic stiffness in a mouse model. Such arterial stiffness in humans is predictive of heart disease and death from heart disease, and it represents an important health problem for the nation.

In the Middle Ages, did contracting leprosy necessarily increase a person's chances of dying? Yes, says a new paper. But it's complicated.

An international research team, including astronomers from the University of Portsmouth, has revealed evidence of dynamical dark energy.

Researchers at University of California San Diego School of Medicine have developed the first mice that lack the Upf3b gene, providing a new model for studying its underlying role in intellectual disabilities and neurodevelopmental disorders.

NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit).

Dieting could be revolutionised, thanks to the ground-breaking discovery by the University of Warwick of the key brain cells which control our appetite.

Students and a scientist at the University of Vermont have discovered 15 new species of 'smiley-faced' spiders--and named them after, among others, Barack Obama, Leonardo DiCaprio, and Bernie Sanders.

Satellite data shows underground water reserves in California’s Silicon Valley rebounded quickly after the recent severe drought. The research points to the success of aggressive conservation measures and lays the groundwork for low-cost monitoring of subterranean water reserves around the world.

Fifty years ago, scientists discovered that the Earth is occasionally hit by cosmic rays of enormous energies. Since then, they have argued about the source of those ultra-high energy cosmic rays—whether they came from our galaxy or outside the Milky Way. The answer is a galaxy or galaxies far, far away, according to a report published Sept. 22 in Science by the Pierre Auger Collaboration.

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That's one conclusion drawn by the authors of a new study published in Systematic Biology.

Some big plant-eating dinosaurs roaming present-day Utah some 75 million years ago were slurping up crustaceans on the side, a behavior that may have been tied to reproductive activities, says a new University of Colorado Boulder study.  

Scientists have helped provide a way to better understand how to enable drugs to enter the brain and how cancer cells make it past the blood brain barrier.

Researchers have developed a medicated skin patch that can turn energy-storing white fat into energy-burning brown fat locally while raising the body’s metabolism. The patch could be used to burn off pockets of unwanted fat and treat metabolic disorders like obesity and diabetes.

University of Washington researchers have published the first analysis looking at how vulnerable the world's freshwater and marine fishes are to climate change. Their paper, appearing online Sept. 11 in Nature Climate Change, used physiological data to predict how nearly 3,000 fish species living in oceans and rivers will respond to warming water temperatures in different regions.

Researchers at University of California San Diego School of Medicine and collaborators discovered a new kind of glycan (sugar chain) that survives even in a 4 million-year-old animal fossil from Kenya, under conditions where ancient DNA does not. While ancient hominin fossils are not yet available for glycan analysis, this proof-of-concept study, published September 11 in Proceedings of the National Academy of Sciences, sets the stage for unprecedented explorations of human origins and diet.

A team of scientists led by the University of Southampton has demonstrated a groundbreaking new method of gene synthesis – a vital research tool with real-world applications in everything from growing transplantable organs to developing treatments for cancer.
