Researchers have unmasked a component of the cell death process that could play a vital role in a better infection-fighting strategy.
Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully "digest" food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless byproduct: nitrogen, the gas that makes up 78% of Earth's atmosphere.
More frequent and intense heatwaves are the most deadly form of extreme weather made worse by global warming, with death tolls sometimes in the thousands, but they can also have devastating economic impacts too, experts say.
Last September, Tasajerito the manatee was found lost in a Colombian swamp, just three days old and separated from his mother.
Floodwaters that rushed through Yellowstone National Park and surrounding communities earlier this week moved through Montana's largest city on Wednesday, flooding farms and ranches and forcing the shutdown of its water treatment plant.
One in five students in the United States will not earn a high school diploma—and young adolescents who fall behind in school risk never catching up, leading to unemployment, poor health and poverty, research has shown.
Most human hearts look nearly identical—muscle cells in the same places, blood vessel structures in the same orientations. Organs such as hearts or stomachs look alike and function the same across individual organisms in a species because cells follow rigorous processes during development that get them precisely where they need to go.
After a long day of work, you might feel tired or exhilarated. Either way, you are affected by what happened to you in the past.
Among the various optics-based tools used in diagnostics, diffuse optics (DO) is rapidly emerging as one of the most attractive technologies. The technique is based on analyzing how light is absorbed and scattered by biological tissues, which relates to the tissue chemical composition and structure. One of the key advantages of DO is that it is non-invasive (it uses low-power near-infrared light)....
Chinese researchers have found a signal that could be from alien civilizations, the country's science ministry is reporting.
On any given day between 2016 and 2019, Heather Stewart could be found snorkeling in between mangroves in the Bocas del Toro archipelago along Panama's Caribbean coast. For years she visited these forests at the interface between land and sea, trying to understand what drove corals to grow inside them. Corals and mangroves often grow near each other in tropical coastal environments, but finding...
Using a newly developed technique, scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg have measured the very small difference in the magnetic properties of two isotopes of highly charged neon in an ion trap with previously inaccessible accuracy. Comparison with equally extremely precise theoretical calculations of this difference allows a record-level test of quantum...
Birds of a feather flock together, but when guppies gather, they get really bad worms.
As part of the European project Moving Marketplaces, the postdoctoral researcher Maria Lindmäe, a member of the Culture and Socio-Ecological Dynamics Research Group (CaSEs) of the Universitat Pompeu Fabra—Barcelona (UPF) Department of Humanities, is the author of an article that investigates the soundscape of different weekly markets in Catalonia. In the study, the author examines the acoustic...
Democracy is widely understood to have arisen in the Mediterranean world about 2,500 years ago before spreading through cultural contact to other parts of the globe. But new research from the University of Georgia Laboratory of Archaeology, together with its partners in the Muscogee Nation, indicates that inhabitants of the Americas may have been practicing democratic-style collective governance...
In a paper published today in Science Advances, researchers at the University of Oxford have developed a method using the polarization of light to maximize information storage density and computing performance using nanowires.
A new analysis of the aftermath of the deadly 2010 Deepwater Horizon accident suggests that, while the reputation of BP—the oil and gas company responsible for the event—declined through 2017, its stock market returns were not significantly affected in the mid- to long-term. William McGuire of the University of Washington in Tacoma and colleagues present these findings in the open-access...
Contrary to some beliefs about internationally sourced dogs, a new survey analysis has found no evidence for a poorer relationship between Canadian dog owners and dogs born outside of Canada versus in Canada. Kai von Rentzell of the University of British Columbia in Vancouver, Canada, and colleagues present these findings in the open-access journal PLOS ONE on June 15, 2022.
Ultrafast light-driven control of magnetization on the nanometer length scale is key to achieve competitive bit sizes in next generation data storage technology. Researchers at Max Born Institute in Berlin and of the large scale facility Elettra in Trieste, Italy, have successfully demonstrated the ultrafast emergence of all-optical switching by generating a nanometer scale grating by interference...
A combination of ecological field methods and cutting-edge artificial intelligence has helped an interdisciplinary research group detect eelgrass wasting disease at nearly three dozen sites along a 1,700-mile stretch of the West Coast, from San Diego to southern Alaska.
Millions of years ago, giant dwarf crocodiles roamed a part of Africa with a taste for our human ancestors.
U.S. teachers and principals are experiencing frequent job-related stress at a rate about twice that of the general population of working adults, according to a new RAND Corporation survey. Well-being is reported as especially poor among Hispanic/Latinx teachers, mid-career teachers and female teachers and principals.
Astronomers in the UK announce today that have established how galaxies like our own Milky Way formed over 10 billion years of cosmic time through an abundance of separate galaxies colliding together.
While using the Atacama Large Millimeter/submillimeter Array (ALMA) to observe large star-forming regions in the Large Magellanic Cloud (LMC), scientists discovered a turbulent push-and-pull dynamic in the star-forming region, 30 Doradus. Observations revealed that despite intense stellar feedback, gravity is shaping the molecular cloud, and against scientific odds, is driving the ongoing...
