Scientists have found the oldest known evidence of the plague, which sparked deadly outbreaks dating back about 5,500 years ago—some 200 years earlier than previously thought.
A newly developed framework for understanding the photoproperties of both natural organic matter and eumelanin, a natural pigment responsible for dark colors in organisms, may inspire advanced sustainable technologies, scientists say.
In May, Prime Minister Mark Carney announced plans to double the capacity of Canada's electricity grid by 2050, using natural gas in the name of "powering Canada strong." Almost all Canadian natural gas these days is derived from hydraulic fracturing—known as fracking—an
The state of the Atlantic Meridional Overturning Circulation (AMOC) has been a hot topic among climate scientists in recent years. The AMOC is crucial for climate regulation because it pulls warm surface water from the tropics north and sends colder, deeper water south,
Scientists have stumbled on a rare dinosaur fossil from Antarctica, tucked away for decades in a drawer.
A small change in acidity can transform the world around us. A squeeze of lemon changes the taste of food. Vinegar preserves vegetables. Stomach acid helps break down a meal. These familiar effects come from protons—tiny charged particles that can reshape chemical interactions.
Extreme floods that once swamped coastal communities only rarely are becoming far more common as climate change caused by humans pushes sea levels higher, according to new research published Wednesday. Experts say the findings are crucial for making plans about floods and
Astronomers have spotted many "red and dead" galaxies in the early universe. These are massive systems that stopped forming stars surprisingly early in cosmic history. Now, they may have found evidence of one in the act of becoming dead: a massive galaxy being stripped of its
Researchers have taken over 120,000 images of salmon lice larvae in seawater and used them to train AI models. The models were much faster and more accurate than experienced biologists at identifying the parasites that feed on the skin and blood of salmonids.
Birds are known for their distinctive plumage that helps them attract mates during the breeding season. For some birds, the path to adulthood is quite linear. One day they are chicks, and a few months later they are fully grown adults with their mature plumage, all set to find
The rockets’ red glare have nothing on these images from Chandra X-ray Observatory
El Nino is here and will quickly develop into a strong event between July and September, fueling the likelihood of extreme weather, the United Nations' climate agency warned Friday.
Europe is still taking stock of a powerful heat wave in late June, but experts are already confident it ranks among the worst ever recorded—even rivaling a freak 2003 episode.
Yeast has been growing in the guts of a frozen mummy called Oetzi the Iceman for thousands of years, scientists have discovered, telling AFP they used it to make a tasty sourdough bread.
Costa Rican scientists may have discovered a new species of ghost shark in Pacific waters near Cabo Blanco and Cano Island.
A punishing heat wave threatened America's July Fourth celebrations, World Cup matches and power grids as near-record temperatures scorched the eastern United States on Friday.
As Australia marks 50 years of NAIDOC Week, honoring the world's oldest living culture, humanity's newest technology has yet to reckon with a simple principle: "nothing about us, without us." The concern is that artificial intelligence (AI), like so many technologies before it,
Diseases spread by insects in the Brazilian Amazon are not randomly distributed but form distinct regional patterns linked to land use, rural economies and environmental change, according to new research led by the Environmental Change Institute (ECI) at the University of Oxford.
Working memory is the information we need to access to complete the tasks we’re engaged in right now, and scientists think it may be closely entwined with consciousness
Throughout human ecological history, we have played a variety of roles within ecosystems around the world. In this so-called Anthropocene era, genomic innovations have given us new and powerful ways to influence the environment and the countless species with whom we share the
The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play system that works as soon as it is powered
By 2050, scientists estimate that antibiotic-resistant infections will be associated with more than 8 million deaths around the world every year.
Museums are supposed to be havens for the collective cultural and scientific heritage of the planet, but specimens sometimes go missing.
In a study published in Science Translational Medicine, a team of researchers led by Dr. Wang Yu from the Shenzhen Institutes of Advanced Technology of the Chinese Academy of Sciences developed PRINCE and Little Prince, dual small-molecule-controlled genome editing systems that
Gentle purchase incentives can lead customers to choose groceries with higher animal husbandry standards more often. A recent study at the University of Bonn at least suggests this. The researchers used two different animal welfare label posters as "nudges." Each poster changed
An experiment that involved feeding a dead goat to a Komodo dragon as well as an analysis of thousands of ancient bones suggests that Homo floresiensis was neither a skilled hunter of big game nor a master of fire
Why do people make the choices they do? Researchers from the Center Synergy of Systems (SynoSys) at TUD Dresden University of Technology, the Max Planck Institute for Human Development, and the University of Basel present their new approach to finding answers to that question.
