Land plants evolved 470 million years ago from algae and have since reshaped our world. Throughout their evolution, ferns have undergone a series of changes that have helped them survive on land. For the first time, researchers have characterized the genome arrangement of tree ferns, which sheds new insight into how ferns evolved.

Researchers at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have found a way to build powerful magnets smaller than before, aiding the design and construction of machines that could help the world harness the power of the sun to create electricity without producing greenhouse gases that contribute to climate change.

We live in a digital age where online shopping is more popular than ever. Sitting in the comfort of one's home and browsing a seemingly endless amount of goods has certainly made our lives easier. Everything's merely a click away. What's not to love about that?

The Biden administration on Monday said the government will plant more than one billion trees across millions of acres of burned and dead woodlands in the U.S. West, as officials struggle to counter the increasing toll on the nation's forests from wildfires, insects and other manifestations of climate change.

Children hold stereotypical views that "brilliance" is a male trait, and this belief strengthens as they grow, up to the age of 12, researchers from Singapore and the United States have reported.

New teachers experienced isolation and self-doubt because of pandemic restrictions, but also demonstrated resilience that could make them even better teachers, a new report has found.

Intimate partner violence—or abuse and aggression in a romantic relationship—is a pervasive global issue. In Uganda, a primarily Christian country in East Africa, 56% of women who've been married report being sexually violated by a current partner. Strong patriarchal beliefs often influence this behavior, but those in positions of power, like religious leaders, can shift traditional gender roles.

Sunlight sparkling on water evokes the rich phenomena of liquid-light interaction, spanning spatial and temporal scales. While the dynamics of liquids have fascinated researchers for decades, the rise of neuromorphic computing has sparked significant efforts to develop new, unconventional computational schemes based on recurrent neural networks, crucial to supporting wide range of modern technological applications, such as pattern recognition and autonomous driving. As biological neurons also rely on a liquid environment... Читать дальше...

Nature creates layered materials like bone and mother-of-pearl that become less sensitive to defects as they grow. Now researchers have created, using biomimetic proteins patterned on squid ring teeth, composite layered 2D materials that are resistant to breaking and extremely stretchable.

Cambridge scientists have developed an artificially intelligent algorithm capable of beating scientists at predicting how and when different materials form ice crystals.

Researchers have discovered a new gene in barley and wheat that controls the angle of root growth in soil, opening the door to new cereal varieties with deeper roots that are less susceptible to drought and nutrient stress, thus mitigating the effects of climate change.

Trilobites, extinct marine arthropods that roamed the world's oceans from about 520 million years ago until they went extinct 250 million years ago at the end of the Permian period, may have grown in a similar fashion and reached ages that match those of extant crustaceans, a new study has found.

California firefighters were making slow progress Monday battling a raging wildfire near Yosemite National Park that will force some residents to evacuate with "just the shirts on their back," officials said.

Greek firefighters battled wildfires on three fronts Monday as flames destroyed around 2,200 hectares (5,400 acres) of woodland in one of the country's most important protected habitats.

Across the U.S., K-12 public school teachers face significant psychological barriers to discussing issues of race and racism with their students, according to new research by a University of Massachusetts social psychologist.

COVID-19 often leads to neurological symptoms, such as a loss of taste or smell, or cognitive impairments (including memory loss and concentration difficulties), both during the acute phase of the disease and over the long term with "long COVID" syndrome. But the way in which the infection reaches the brain was previously unknown. Scientists from Institut Pasteur and CNRS laboratories have used state-of-the-art electron microscopy approaches to demonstrate that SARS-CoV-2 hijacks nanotubes, tiny bridges that link infected cells with neurons.

Even if they've never served time in prison, people who have felony convictions still have difficulty accessing stable housing, according to new research from a Rice University sociologist.

Microbes growing on flowers have adverse effects on their yields. This is why plants are quick to shed their flowers, reveals a new study involving both field experiments and plant microbiome analysis.

Around 30 million people in Europe live in mountain valleys. A large part of this population is more affected by air pollution than previously assumed. This is the conclusion of a Slovenian-German research team from measurements in the Northern Dinaric Alps. Due to temperature inversions in winter, pollutants are trapped in the valleys to such an extent that soot and fine dust could reach alarming levels even in small villages, as they otherwise occur mainly in the centers of congested metropolises...

More than a dozen images of butterflies adorn the front of Claudia Galeno-Sanchez's home in the Pilsen neighborhood. There are monarch butterflies spreading their wings and many other colorful ones sprinkled in between. The small house stands out from the tall buildings on the block.

Does it feel sweltering in your neighborhood, yet pleasant at the park a few blocks away? You might be living on an urban heat island.

Reducing sugar consumption would have important benefits in the fight against climate change, as well as in the recovery from the health and economic crises associated with the coronavirus pandemic. This is the conclusion of a study by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB) that analyses the potential climate and sustainability co-benefits of reducing sugar consumption through redirecting existing sugar cropland to alternative uses.

It's getting hotter in Greenland and last weekend temperatures rose enough to cause 18 billion tons of the country's ice sheet to melt over a three-day period.

There's nothing quite like taking a dip in the ocean in the summertime. Sand, sunshine and the smell of salt water are practically staples when the weather gets warm.

Grapevine Trunk Diseases, or GTDs, are the bane of vineyard owners worldwide, and as of 2012, were responsible for more than $1.5 billion in annual economic damages. While researchers have long known that a host of pathogenic fungi combine to gang up on grapevines, the mechanics of how these GTD-causing fungi work has remained a mystery.
