The first all-female spacewalk is back on, six months after a flap over spacesuits led to an embarrassing cancellation.

A federal agency has rejected an iconic Alaska tree for listing as a threatened species due to climate warming.

Researchers have developed a new non-invasive optical imaging system that promises to improve diagnosis and treatments for dry eye disease. Dry eye, which often causes irritation and blurred vision, occurs when there is instability in the inner layer of the tear film that protects the outside of the eye.

Over the last two decades, tremendous advances have been made in the field of quantum information science. Scientists are capitalizing on the strange nature of quantum mechanics to solve difficult problems in computing and communications, as well as in sensing and measuring delicate systems. One avenue of research in this field is optical quantum information processing, which uses photons—tiny...

Fish use colorful patterns to signal to each other, including advertising for mates and warding off rivals. Studying these colors, especially in small and squirmy species, sometimes entails anesthetizing and photographing the fish to obtain color measurements from digital images.

A team led by scientists at the University of Washington has designed and tested a 3-D-printed metamaterial that can manipulate light with nanoscale precision. As they report in a paper published Oct. 4 in the journal Science Advances, their designed optical element focuses light to discrete points in a 3-D helical pattern.

Joe Nuth loves dust. Among astronomers, that puts him in a minority.

Last month was the equal hottest September in history, the European Union's satellite monitoring service said Friday, the fourth month in a row with near- or record-breaking temperatures.

In materials science and quantum physics, flat bands and correlated behaviors within the "magic angle" twisted bilayer graphene (tBLG) has sparked significant interest, although many of its properties face intense debate. In a new report published in Science Advances, Emilio Codecido and colleagues in the departments of physics and materials science in the U.S. and Japan observed both...

Researchers at Western University have developed a new way to deliver the DNA-editing tool CRISPR-Cas9 into microorganisms in the lab, providing a way to efficiently launch a targeted attack on specific bacteria.

With climate change comes increasing water shortages, and potentially longer periods of drought. As policymakers look urgently to wastewater recycling to stem the gap in water resources, the question is— how best to reuse water and ensure public safety. New and emerging contaminants like antibiotic resistant genes (ARGs) pose a potential hazard to public safety and water security. One concern is...

As New Jersey and other states lead nationwide efforts to address climate change, they are recognizing the disproportionate impact that climate change has on disadvantaged populations, according to a new Rutgers report.

Women who experience intimate partner violence, including physical, emotional, and controlling abuse, are more likely to suffer material hardship—the inability to purchase food, housing, utilities, medical care or other needs for a healthy life, according to a Rutgers-led study.

The Netherlands is featured in this false-color image captured by the Copernicus Sentinel-2 mission. This image was processed in a way that included the near-infrared channel, which makes vegetation appear bright red.

Scientists have chosen an ice floe on which to begin setting up a research camp for a year-long international expedition to study the Arctic, Germany's Alfred Wegener Institute said Friday.

Newly developed 3-D imaging technology has allowed scientists to map an area of cold-water coral reefs off the coast of Scotland to see whether it has recovered since being declared a Marine Protected Area 16 years ago. The images show that in areas of the Darwin Mounds that had been heavily trawled, coral growth is still very sparse, and there has been no real recolonization. However, healthy...

The work of a Montana State University professor examining the economic impacts of colony collapse disorder among commercial honeybees was published in the Journal of the Association of Environmental and Resource Economists last month.

The idea of a four-day working week is gaining traction. Recently, several high-profile companies have trialled reduced hours. And in the UK, the Labour Party has pledged a 32-hour four day work week within ten years should it come to power.

Nature documentaries raise species awareness and promote pro-conservation behaviours, but don't lead to donations to conservation charities, a new Irish study has revealed.

There are many reasons NASA is pursuing the Artemis mission to land astronauts on the moon by 2024: It's a crucial way to study the moon itself and to pave a safe path to Mars. But it's also a great place to learn more about protecting Earth, which is just one part of the larger Sun-Earth system.

In 2017, Salk scientists reported that tilting a frozen protein sample as it sat under an electron microscope was an effective approach to acquiring better information about its structure and helping researchers understand a host of diseases ranging from HIV to cancer. Now, they have developed a mathematical framework that underlies some of those initial observations.

According to condensed matter physics predictions, at a high enough pressure, hydrogen should dissociate and transform into an atomic metal. However, the exact pressure range at which this occurs has not yet been ascertained, and the process through which hydrogen becomes a metal is still somewhat unclear.

American farmer and poet Wendell Berry said of the first Europeans in North America that they came with vision, but not with sight. They came with vision of former places but not the sight to see what was before them. Instead of adapting their vision to suit the place, they changed the landscape to fit their vision.

Recently published climate research led by Sanjiv Kumar, a professor in Auburn University's School of Forestry and Wildlife Sciences, has already provided the basis of a pioneering new outlook product that is capable of forecasting drought.
