A shark that has become a viral sensation in South Korea was coaxed out of a canal in which it was stuck, authorities said on Wednesday, as falling temperatures raised concerns for its survival.
Just like gloves, molecules can have left- and right-handed—or mirror-image—forms. Because the left- and right-handed molecules are still very similar, scientists have had trouble separating them from each other. But a team of researchers in Japan might have found a solution. In their new study, published in Science Advances, the team successfully separated an equal mixture of mirror-image molecules created by replacing hydrogen with deuterium in one form.
Scientists from RMIT University and Riga Technical University in Latvia have shown that static charge left on surfaces can be controlled, which may have big benefits for companies needing to avoid the little zap in production of common household goods. The discovery could even one day help stop powders such as protein, chocolate malt powders and coffee from clumping.
Sitting in his narrow dugout canoe, Jean-Romeo Senguemboli frowned at the meager catch in his nets on the Central African Republic's Mbali River, where experts say deforestation is devastating the fish population.
Sailor Matt Rutherford has dreamed for several years of becoming the first person to circumnavigate the Arctic Ocean solo, nonstop and unassisted. He finally set out from western Greenland on June 25 to achieve this goal, but threatening encounters with Russia's security agency less than two months later forced him to reverse course.Rutherford is the founder and executive director of the nonprofit environmental organization Ocean Research Project, which gathers and analyzes marine data from a sailboat. His route took him around the southern tip of Greenland, through the Denmark Strait and into the Greenland Sea. From there, he sailed through the Norwegian and Barents seas, and reached Russia...
A possible reason for the overdose deaths drop is more use of naloxone, which reverses opioid overdoses. But while still a key tool, its use fell too.
Besides building crewed outposts at the lunar south pole, where else should astronauts go on the moon? An authoritative new report has suggestions
Losing more ground in the fight against climate change, humanity is heading for a hotter world than experts projected last year—and the United States is a big reason for that, a new United Nations report says.
Many structures in biology are bounded by membranes, but not all of them. Droplets of a liquid called a coacervate, which form when oppositely charged molecules come together in water, have attracted attention as models for membraneless compartments inside cells and for "protocells," hypothetical primitive cells that may have preceded modern ones.
An international study led by the Institute of Evolutionary Biology (IBE, CSIC-UPF) in Barcelona, the Natural Sciences Museum of Barcelona, Harvard University and the University of the Basque Country (EHU) has reconstructed the genetic history of the Iberian Peninsula between the first and eighth centuries A.D. using 243 ancient genomes from 31 archaeological sites.
Moderately cold temperatures have proven to effectively extend lifespan and delay age-related decline in animals. However, how cold temperatures trigger these beneficial effects at the molecular level has remained largely unclear.
Earlier this year, an outbreak of Andes hantavirus on a cruise ship, which killed three passengers and sickened 13, highlighted the lack of approved vaccines or treatments for the virus. In a study published in Nature, scientists at Albert Einstein College of Medicine and collaborators from Institut Pasteur and LSU Health Shreveport show how the virus recognizes its target on a human cell, a finding that could lead to effective therapies against Andes virus and other hantaviruses.
For the first time, Northwestern University physicists have coaxed a single positron—the antimatter counterpart of an electron—into an exquisitely controlled quantum state.
There are an estimated 10 quintillion insects alive on Earth at any given time. That's 10,000,000,000,000,000,000 individual insects. But how many species are there, why do we need them, and what would happen if their numbers continued to fall? Dr. Alex Dittrich, a zoologist at Nottingham Trent University, explains why these small creatures play such a big role in keeping our planet functioning.
For the first time, scientists can make quantum measurements on a positron particle
New research led by the University of Michigan provides utilities and policymakers with forecasts that can help them better prepare for future extremes in peak energy demand in the United States.
Marine heat waves are usually seen as destructive events that can disrupt entire ocean ecosystems and trigger massive environmental damage. In 2018 and 2019, an extreme heat wave hit the Bering Sea, causing spring sea ice levels to plummet.
This year’s photomicrography contest captured the wonders of the very small, from flying ink droplets to the most adorable jumping spider you've ever seen.
A massive study of more than 460,000 Americans found that ultra-processed foods were not associated with increased colorectal cancer risk overall, challenging a widely held assumption. While processed meat was linked to higher cancer incidence, ultra-processed whole grains and dairy products were associated with lower incidence.
Scientists have uncovered an unexpected danger lurking inside cells: too much RNA can damage the structures responsible for producing energy. A new study found that excess RNA, including the normally essential messenger RNA (mRNA), can directly disrupt mitochondria without relying on the immune system. The discovery could help explain how viral infections and certain aging-related diseases damage cells.
