SpaceX's third crew has an attack helicopter pilot, a former Air France pilot, a Japanese rocket scientist and an oceanographer.

SpaceX launched four astronauts into orbit Friday using a recycled rocket and capsule, the third crew flight in less than a year for Elon Musk's rapidly expanding company.

The camera system used to survey seabeds could be seriously underestimating disturbances to ecosystems, according to new research from Heriot-Watt University.

Introducing chemical impurities to a material for the sake of tailoring its properties or performance—sometimes called doping—has long proven vital in electronic engineering, especially the fabrication of semiconductors and other microelectronic components.

Chemists of the University of Bonn developed a computational tool for the analysis of conformational entropies of flexible molecules. Their method enables the thermodynamic investigation of complicated chemical systems by combination of modern quantum chemical and classical models. In a successful attempt of simplifications, important contributions to the entropy can be calculated with minimal...

Transportation is the largest source of greenhouse gas emissions in California. In order to achieve the state's goals of carbon neutrality by 2045 and avoid the worst impacts of climate change, decarbonizing this sector is essential. But such a transition is unlikely to occur rapidly without key policy intervention.

A device from Los Alamos National Laboratory researchers is not quite the Star Trek "tricorder" medical scanner, but it's a step in the right direction. The Portable EnGineered Analytic Sensor with aUtomated Sampling (PEGASUS) is a miniaturized waveguide-based optical sensor that can detect toxins, bacterial signatures, viral signatures, biothreats, white powders and more, from samples such as...

Police stops of people of color escalating in violence or death have gained national attention since the death of George Floyd last May.

"NASA is a scientific leader, globally and nationally," said Denise Thaller, director of NASA's Environmental Management Division. "We embody that focus on the stewardship of the Earth, so we need to lead by example. We need to evaluate everything we do and make sure we're reducing our impacts on the Earth while we study the Earth."

NASA's STEREO-A and ESA/NASA's SOHO spacecraft detected a coronal mass ejection, or CME, leaving the sun on April 17 at 12:36 p.m. EDT. This CME did not impact Earth but did move toward Mars, passing the planet in the late evening and early morning hours of April 21 and 22.

Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles.

An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science.

A new real-time, 3D motion tracking system developed at the University of Michigan combines transparent light detectors with advanced neural network methods to create a system that could one day replace LiDAR and cameras in autonomous technologies.

The tree of life just got a little bigger: A team of scientists from the U.S. and China has identified an entirely new group of microbes quietly living in hot springs, geothermal systems and hydrothermal sediments around the world. The microbes appear to be playing an important role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane.

Among the first lessons any grade school science student learns is that white light is not white at all, but rather a composite of many photons, those little droplets of energy that make up light, from every color of the rainbow—red, orange, yellow, green, blue, indigo, violet.

Rats, by and large, aren't terribly popular animals. But while you don't want an infestation of common black rats living in your house, their distant cousins in the Philippines are downright cuddly. These "giant cloud rats" live in the treetops of misty mountain forests, and they fill an ecological role occupied by squirrels in the US. And, it turns out, we have new evidence that they've been...

The Karukinka natural park on Chile's side of the Tierra del Fuego archipelago guards a treasure trove of ancient beech trees saved from the chainsaws of loggers.

World leaders participating in the virtual Earth Day summit are unanimous: fighting climate change will be good for economic growth worldwide.

Down an overgrown country road, three startled wild horses with rugged coats and rigid manes dart into the flourishing overgrowth of their unlikely nature reserve: the Chernobyl exclusion zone.

Four astronauts arrived at their launch pad early Friday morning for a SpaceX flight to the International Space Station, the company's third bon voyage for a NASA crew in under a year.

SpaceX is set to launch its third crew to the International Space Station an hour before sunrise Friday, recycling a rocket and spacecraft for the first time.

New photonics research paves the way for improved lasers, high-speed computing and optical communications for the Army.

Researchers from Nanjing University, National Sun Yat-sen University, and Northwestern University published a new paper in the Journal of Marketing that shows that the spatial distance between products and consumers can affect perceived value and willingness to pay.

University of Arkansas law professor Jordan Blair Woods challenges the conventional wisdom that only police can enforce traffic laws.
