Norwegian experts say an unusually large meteor was visible over large parts of southern Scandinavia and illuminated southeast Norway with a powerful flash of light for a few seconds as many observers were reported to also hear a roaring sound afterwards.

Computers have been able to quickly process 2D images for some time. Your cell phone can snap digital photographs and manipulate them in a number of ways. Much more difficult, however, is processing an image in three dimensions, and doing it in a timely manner. The mathematics are more complex, and crunching those numbers, even on a supercomputer, takes time.

Minnesota has become the latest state to adopt California's stricter standards for tailpipe emissions and a mandate for automakers to get more zero-emission vehicles onto sales lot.

Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.

Metal additive manufacturing (AM) promises to revolutionize the way we produce and use certain parts. Reducing material waste and labor time, metal AM simplifies the steps for creating complex geometry parts when compared to conventional manufacturing methods.

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates—that is, turns from solid to gas.

Just because you were in space doesn't mean you get the wings of an astronaut.

In the longest study to date on the impact of princess media on consumers, new research from BYU professor Sarah Coyne found that children who engaged with princess culture were more likely to later hold progressive views about women and subscribe less to attitudes of toxic masculinity.

Indigenous communities can now assess the quality and sweetness of their wild-harvested native bush fruits in the field, rather than sending samples off to food science laboratories.

More than 99% of the visible universe exists in a superheated state known as plasma—an ionized gas of electrons and ions. The motion of these charged particles produces magnetic fields that form an interstellar magnetic web. These magnetic fields are important for a wide range of processes, from the shaping of galaxies and the formation of stars to controlling the motion and acceleration of...

IIASA researchers and international colleagues explored the potential of using finely ground rock to help with the removal of CO2 from the atmosphere on the road to achieving net-zero emissions and keeping global warming below 1.5°C.

A Monash University study into the experiences of school leaders in 2020 found those who engaged in community, communication and compassion-based responses, successfully led their school community through crises and times of uncertainty.

Methane concentrations in the atmosphere have more than doubled over the last 150 years and mitigation of methane emissions will play a vital role in enabling climate change mitigation strategies. Understanding current and future methane inventories at a regional scale will be a key element in developing and implementing successful solutions. Current regional scale isotopic methane data is not...

In recent years, fluorescent metal-organic frameworks (MOFs) have been demonstrated as a promising strategy for constructing sensors. However, most of the research studies on fluorescent MOF sensors have focused on the design and synthesis of three-dimensional (3D) MOF crystals on the order of micrometers and have not exerted the best detection performance of MOF structures. Two-dimensional (2D)...

Researchers from Tokyo Metropolitan University have developed a new technology which allows non-contact manipulation of small objects using sound waves. They used a hemispherical array of ultrasound transducers to generate a 3D acoustic field that stably trapped and lifted a small polystyrene ball from a reflective surface. Their technique employs a method similar to laser trapping in biology, but...

A new study has found plastic accumulation in foods may be underestimated. There is also concern these microplastics will carry potentially harmful bacteria such as E. coli, which are commonly found in coastal waters, up the food chain.

As California endures an increasingly brutal second year of drought, state water regulators are considering an emergency order that would bar thousands of Central Valley farmers from using stream and river water to irrigate their crops.

When Erin Babnik awoke on the morning of Nov. 8, 2018, in Paradise, California, she thought the reddish glow outside was a hazy sunrise.

The COVID-19 pandemic and the politicization of health-prevention measures such as vaccination and mask-wearing have highlighted the need for people to accept and trust science.
