For the sixth time in the Atlantic hurricane season, people in Louisiana are once more fleeing the state's barrier islands and sailing boats to safe harbor while emergency officials ramp up command centers and consider ordering evacuations.

Hurricane Delta emerged into the Gulf of Mexico on Wednesday and headed toward Louisiana after making landfall just south of the Mexican resort of Cancun, toppling trees and cutting power to residents of the Yucatan peninsula's resort-studded coast.

Broiler chicken producers the world over are all too familiar with coccidiosis, a parasite-borne intestinal disease that stalls growth and winnows flocks. Various approaches, developed over decades, have been used to control coccidiosis, but the disease remains widespread.

All cells with nuclei, from yeast to humans, are organized like cities, with a variety of small compartments—organelles—that serve as factories where various types of work are done. Some of those factories, like the ones that break down and recycle molecules, need to continually pump in protons—hydrogen atoms with their electrons stripped off—to maintain the acidic environment they need to...

How things deform and break is important for engineers, as it helps them choose and design what materials they're going to use for building things. Researchers at Aalto University and Tampere University have stretched metal alloy samples to their breaking point and filmed it using ultra-fast cameras to study what happens. Their discoveries have the potential to open up a whole new line of research...

A research team at the Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) consisting of Visiting Scientist Chiaki Kobayashi, Project Researcher at the time Shing-Chi Leung (currently at the California Institute of Technology), and Senior Scientist Ken'ichi Nomoto have used computer simulations to follow the explosion, nuclear reaction, production of elements, and...

Astronomers have found compelling evidence that planets start to form while infant stars are still growing. The high-resolution image obtained with the Atacama Large Millimeter/submillimeter Array (ALMA) shows a young proto-stellar disk with multiple gaps and rings of dust. This new result, just published in Nature, shows the youngest and most detailed example of dust rings acting as cosmic...

A Florida State University researcher is part of a team that has found varying projections on global warming trends put forth by climate change scientists can be explained by differing models' predictions regarding ice loss and atmospheric water vapor.

Working with fish, birds and mice, Johns Hopkins Medicine researchers report new evidence that some animals' natural capacity to regrow neurons is not missing, but is instead inactivated in mammals. Specifically, the researchers found that some genetic pathways that allow many fish and other cold-blooded animals to repair specialized eye neurons after injury remain present in mammals as well, but...

Checkout bags, straws and four other single-use plastic items will be banned in Canada by the end of 2021, the environment minister announced Wednesday, while acknowledging the nation is trailing Europe in recycling efforts.

Hurricane Delta tore across Mexico's Yucatan Peninsula Wednesday, toppling trees, ripping down power lines and lashing a string of major beach resorts with winds of up to 110 miles (175 kilometers) per hour.

Brain cells have been found in exceptionally preserved form in the remains of a young man killed in the eruption of Mount Vesuvius almost 2,000 years ago, an Italian study has revealed.

The commander of Boeing's first astronaut flight has pulled himself off the crew so he's on Earth—not at the International Space Station—for his daughter's wedding next year.

Wednesday's Nobel Prize in chemistry was a historic first for women.

University of Maryland scientists have developed a method to determine the structures of large RNA molecules at high resolution. The method overcomes a challenge that has limited 3-D analysis and imaging of RNA to only small molecules and pieces of RNA for the past 50 years.

Results from a large-scale survey of households in Latin America and the Caribbean show that the negative economic impacts of the COVID-19 pandemic have been concentrated among those who had lower incomes prior to the pandemic, according to a study published October 7 in the open-access journal PLOS ONE by Nicolas Bottan of Cornell University, Bridget Hoffmann and Diego Vera-Cossio of the...

The reintroduction of seagrass into Virginia's coastal bays is one of the great success stories in marine restoration. Over the past two decades, scientists and volunteers have broadcast more than 70 million eelgrass seeds within 4 previously barren seaside lagoons, spurring a natural expansion that has so far grown to almost 9,000 acres—the single largest eelgrass habitat between North Carolina...

Ringed seals and other Arctic marine mammals are important in the diet of Arctic Indigenous peoples. A study spanning 45 years of testing indicates that mercury concentrations in ringed seals from the Canadian Arctic have remained stable, showing very limited declines over time.

New research has shed light on how various political campaign activities influence voters. It found that a candidate's mass media advertising is more likely to influence independent voters, while the campaign's 'ground game,' targeting voters through grassroots outreach, is more effective at reaching a candidate's base.

On hearing that they had been awarded a Nobel Chemistry Prize for their groundbreaking work on gene-editing Jennifer Doudna and Emmanuelle Charpentier said they hoped it would inspire a new generation of women in science.

The Nobel prizes remain very much a man's world, especially in science, but with three female laureates already named this year, women are slowly making their mark.

The team's findings have been published in Nature: Scientific Reports: "Transition delay using biomimetic fish scale arrays," and in the Journal of Experimental Biology: "Streak formation in flow over biomimetic fish scale arrays."

Russian authorities Wednesday opened an investigation into suspected toxic waste pollution off the Kamchatka peninsula on its Pacific coast which has led to the mass death of marine animals.

Two weeks after the World Health Organization declared the coronavirus a global pandemic, the UK government announced Everyone In, a scheme to protect people sleeping rough from catching the virus.
