NASA is making final preparations for its Perseverance Mars rover to collect its first-ever sample of Martian rock, which future planned missions will transport to Earth. The six-wheeled geologist is searching for a scientifically interesting target in a part of Jezero Crater called the "Cratered Floor Fractured Rough."

Smoke and ash from massive wildfires in the American West shrouded the sky and led to air quality alerts on parts of the East Coast on Wednesday as the effects of the blazes were felt 2,500 miles (4,023 kilometers) away.

In the race to combat climate change, capturing carbon dioxide (CO2) emissions has been touted as a simple road to reach net-zero emissions by 2050. While the science behind carbon capture is sound, current technologies are expensive and not optimized for all settings. A cover story in Chemical & Engineering News, the weekly newsmagazine of the American Chemical Society, highlights the current...

The ASU-led team that built NASA's Lunar Polar Hydrogen Mapper, or "LunaH-Map" for short, has safely delivered their spacecraft to NASA's Kennedy Space Center in Florida in preparation for a launch expected later this year on NASA's Space Launch System (SLS) Artemis I rocket.

A new analysis of global datasets shows low-income countries are significantly more likely to be impacted by both toxic pollution and climate change—and provides a list of at-risk countries most (and least) able to immediately begin direct efforts toward pollution risk reduction, according to a study published July 7, 2021 in the open-access journal PLOS ONE by Richard Marcantonio from the...

An analysis of Polish parents between the ages of 18 and 40 suggests that about 13 percent regret having children, and this regret is associated with poor psychological health, among other factors. Konrad Piotrowski of SWPS University in Poznan, Poland, presents these findings in the open-access journal PLOS ONE on July 21, 2021.

Most vessels are exceeding speed limits in areas designated to protect critically endangered North Atlantic right whales, of which only around 360 remain, a report said Wednesday.

Domesticated rabbits come in all sizes and colors, including tiny Netherland Dwarfs, floppy-eared French lops, Flemish Giants, and fluffy Angoras.

Gluten is a protein complex found in cereals such as wheat, rye and barley. It is responsible for the elastic texture of dough so that loaves and rolls can be baked into different shapes while remaining flexible and crusty. It also lengthens the shelf life of bread at room temperature, when associated with preservatives.

Record rains have inundated central China with floods striking an underground subway system, damaging dams and riverbanks, and causing landslides and building collapses.

It's the quintessential French delicacy, but increasingly targeted by animal welfare activists: Can foie gras grown from duck cells find a place at the table for gourmet food fans?

A mysterious ailment has sickened and killed thousands of songbirds in several mid-Atlantic states since late spring. While scientists are still racing to confirm the cause, it seems juvenile birds may be most susceptible. The U.S. Geological Survey, which oversees responses to some natural hazards and risks, has recommended that people temporarily take down bird feeders and clean out bird baths...

Russia on Wednesday successfully launched a long-delayed lab module for the International Space Station that is intended to provide more room for scientific experiments and space for the crew.

Scientists have developed a new way to model and map the health of coral reef ecosystems using data collected on the Khaled bin Sultan Living Oceans Foundation's Global Reef Expedition. This innovative method, presented today at the International Coral Reef Symposium (ICRS), can determine which natural and anthropogenic factors are most likely to lead to persistently vibrant coral and fish...

As the Summer Olympics draw near, the world will shift its focus to photo finishes and races determined by mere fractions of a second. Obtaining such split-second measurements relies on faultlessly rounding a raw time recorded by a stopwatch or electronic timing system to a submitted time.

Cornell researchers have developed nanostructures that enable record-breaking conversion of laser pulses into high-harmonic generation, paving the way for new scientific tools for high-resolution imaging and studying physical processes that occur at the scale of an attosecond.

Machine learning, a data analysis method used to automate analytical model building, has reshaped the way scientists and engineers conduct research. A branch of artificial intelligence (AI) and computer science, the method relies on a large number of algorithms and broad datasets to identify patterns and make important research decisions.

Managing earnings involves the manipulation of financial reporting by publicly traded companies in order to misrepresent how well they're really doing. Companies might insert a low-ball estimate of bad debt or delay the announcement of a capital project—anything that can help a struggling public company report an extra cent or two of earnings per share in its quarterly or annual statement and...

ESA will further increase the competitiveness and environmental sustainability of Europe's Vega launch system beyond 2025 through a contract signed with Avio in Italy.

People living in the private rented sector are forced to make hard choices in order to meet their basic needs, a new study from the University of Glasgow led UK Collaborative Centre for Housing Evidence [CACHE] reveals.

Investing in structural home repairs in historically segregated, low-income, Black and Latino neighborhoods has been associated with reduced crime rates. In Philadelphia, when a home received repairs through a city-funded program, total crime dropped by 21.9% on that block, and as the number of repaired houses on a block increased, instances of crime fell even further, according to research from...

According to the latest cosmological models, large spiral galaxies such as the Milky Way grew by absorbing smaller galaxies, by a sort of galactic cannibalism. Evidence for this is given by very large structures, the tidal stellar streams, which are observed around them, which are the remains of these satellite galaxies. But the full histories of the majority of these cases are hard to study,...

Eight in 10 of the world's poorest children—almost 50 million boys and girls—are missing out on vital education in the first few years of their life because of a chronic lack of funding in pre-primary education, according to a new report published today.

According to a new report co-written by Illinois Natural History Survey postdoctoral researcher Valeria Trivellone, climate change, poverty, urbanization, land-use change and the exploitation of wildlife all contribute to the emergence of new infectious diseases, which, in turn, threaten global food security. Trivellone spoke with News Bureau life sciences editor Diana Yates about how global...
