The Sun emitted a significant solar flare peaking at 11:35 a.m. EDT on Oct. 28, 2021. NASA's Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Targeted mutations to the genome can now be introduced by splitting specific mutator enzymes and then triggering them to reconstitute, according to research from the Perelman School of Medicine at the University of Pennsylvania. Led by graduate student Kiara Berríos under the supervision of Rahul Kohli, MD, Ph.D., an associate professor of Infectious Diseases at Penn, and Junwei Shi, Ph.D., an assistant professor of Cancer Biology, the investigations uncovered a novel gene editing technique that...

In a first-of-its-kind study, a team of researchers attempted to quantify the massive loss of historical lands by Indigenous nations across the United States since European settlers first began laying claim to the continent.

Sometimes plant cells don't have just one large central cavity, or vacuole, but several. These can even have different functions. How is that possible? A team led by UvA biologists Ronald Koes and Francesca Quattrocchio took another step towards solving this fundamental biological riddle. Their discovery has been published in the leading scientific journal Cell Reports.

Hydrogen is increasingly viewed as essential to a sustainable world energy economy because it can store surplus renewable power, decarbonize transportation and serve as a zero-emission energy carrier. However, conventional high-pressure or cryogenic storage pose significant technical and engineering challenges.

Damaged coral reefs show slower than expected recovery for up to six years before switching to a faster phase of regrowth, according to new research.

In a dry year in the West, when the world turns crispy and cracked, rivers and streams with their green, lush banks become a lifesaving yet limited resource.

For 10 years, in the Atlantic Forests, researchers compared forests used by herbivorous mammals, including the lowland tapir (Tapirus terrestris) and the white-lipped peccary (Tayassu pecari), and areas in which these animals have been barred from access due to exclosure plots (fences). The main conclusion is that the areas used by these herbivores show lower loss of diversity than fenced areas.

There are clear and enduring regional divides across Great Britain, finds an intergenerational assessment of the social mobility of British families between 1851 and 2016, carried out by University College London (UCL) researchers at the Consumer Data Research Centre (CDRC).

A University of Leicester study of data captured in orbit around Jupiter has revealed new insights into what's happening deep beneath the gas giant's distinctive and colorful bands.

New findings from NASA's Juno probe orbiting Jupiter provide a fuller picture of how the planet's distinctive and colorful atmospheric features offer clues about the unseen processes below its clouds. The results highlight the inner workings of the belts and zones of clouds encircling Jupiter, as well as its polar cyclones and even the Great Red Spot.

Cracked phone screens could become a thing of the past thanks to breakthrough research conducted at The University of Queensland.

Partisanship is a particularly potent source of group identity in contemporary American politics, and a new paper co-written by a University of Illinois Urbana-Champaign expert in political psychology says the growing chasm between opposing groups isn't limited to interactions in the political realm.

New results from a more-than-decade long physics experiment offer insight into unexplained electron-like events found in previous experiments. Results of the MicroBooNE experiment, while not confirming the existence of a proposed new particle, the sterile neutrino, provide a path forward to explore physics beyond the Standard Model, the theory of the fundamental forces of nature and elementary particles.

Deep in an Indiana forest, a team of scientists skulked atop hillsides after dark. Carrying radios and antennas, they fanned out, positioning themselves on opposite ridges to wait and listen. Their quarry? Endangered Indiana bats and threatened northern long-eared bats.

A hypnotizing vortex? A peek into a witch's cauldron? A giant space-spider web?

An international team of researchers, led by University of Winnipeg palaeoanthropologist Dr. Mirjana Roksandic, has announced the naming of a new species of human ancestor, Homo bodoensis. This species lived in Africa during the Middle Pleistocene, around half a million years ago, and was the direct ancestor of modern humans.

Polyethylene is the most abundantly manufactured plastic in the world. Due to properties like durability, it has many diverse, and even long-term uses. Professor Stefan Mecking's team in the Department of Chemistry at the University of Konstanz has now incorporated polar groups in the material's molecular chains in order to expand its properties and simultaneously reduce the problematical persistence of plastic in the environment. The desired favorable properties of polyethylene remain unchanged afterwards. Читать дальше...

The history of indigenous displacement and land dispossession is a long, troubled and still incomplete history of the United States. It's been widely reported that since 1776, the year America was founded, the U.S. has seized more than one billion acres of land that was home to hundreds of nations of American Indians. Yet many Americans are only vaguely familiar with how this situation came to be.

Scientists discover the genetics inside legumes that control the production of an oxygen-carrying molecule, crucial to the plant's close relationships with nitrogen-fixing bacteria.

In recent decades, people in the UK have watched climate change shift from being an abstract threat discussed on the news to an increasingly common presence in everyday life. As the frequency and intensity of heatwaves, floods and other extreme weather events has risen, so has public concern about climate change. A 2019 poll found 80% of people were fairly or very worried, while a more recent survey ranked climate change as the most important issue.

Coastal wetlands support diverse and vital ecosystems central to coastal areas' biodiversity and economic vitality. However, coastal wetlands are threatened by sea level rise that can lead to flooding and land use changes that alter the way people can live or work in these areas. These impacts are large. Approximately 600 million people live less than 10 meters, approximately 6 miles, above sea level, while 2.4 billion people live within 100 km, or around 60 miles, of the coast.

Maurice Caldwell spent 20 years in prison before his wrongful conviction for a 1990 murder in San Francisco was finally overturned.

When a massive wildfire tears through a landscape, what happens to the animals?

Individual climate actions are an essential pillar for achieving the climate change mitigation goals of the Paris Agreement. The United Nations Framework Convention on Climate Change recognizes the importance of individual efforts and lists specific actions that citizens can take. Even with many potential actions available to citizens, progress towards the Paris Agreement lags behind the targets, and citizen lifestyle changes have yet to make a substantial impact in achieving these goals. An improved... Читать дальше...
