Planetary scientists discover brief presence of water in Arabia Terra on Mars
As part of a team of collaborators from Northern Arizona University and Johns Hopkins University, Northern Arizona University (NAU) Ph.D. candidate Ari Koeppel recently discovered that water was once present in a region of Mars called Arabia Terra......»»
Skyrmions move at record speeds: A step towards the computing of the future
An international research team led by scientists from the CNRS has discovered that the magnetic nanobubbles known as skyrmions can be moved by electrical currents, attaining record speeds up to 900 m/s......»»
Polystyrene microplastics shown to enhance invasion of exotic submerged macrophytes
Submerged macrophyte invasions and microplastic pollution are major challenges in the context of global change and pose a serious threat to aquatic environments. The presence of microplastics in aquatic ecosystems alters plant function, sediment micr.....»»
Scientists discover forests that may resist climate change
While it's common knowledge that mountaintops are colder than the valleys below, a new University of Vermont (UVM) study is flipping the script on what we know about forests and climate......»»
Scientists explore the strategies of defects and nanostructure fabrication for promoting piezocatalytic activity
As an important chemical raw material, hydrogen peroxide (H2O2) is widely applied in various aspects of industry and life. The industrial anthraquinone method for H2O2 production has the serious flaws, such as high pollution and energy consumption. B.....»»
Drawing a line back to the origin of life: Graphitization could provide simplicity scientists are looking for
Scientists in Cambridge University suggest molecules, vital to the development of life, could have formed from a process known as graphitization. Once verified in the laboratory, it could allow us to try and recreate plausible conditions for life's e.....»»
Materials follow the "Rule of Four," but scientists don"t know why yet
Scientists are normally happy to find regularities and correlations in their data—but only if they can explain them. Otherwise, they worry that those patterns might just be revealing some flaw in the data itself, so-called experimental artifacts......»»
First evidence of ancient human occupation found in giant lava tube cave in Saudi Arabia
If you look from above, you can see thousands of stone structures dotting the landscape of the Arabian peninsula. On the ground, you can find a bounty of stone tools and ancient fireplaces scattered along the edges of ancient lakes, as well as rock a.....»»
Bird flu in cattle: What are the concerns surrounding the newly emerging bovine H5N1 influenza virus?
The confirmed presence of bird flu in American dairy cattle in a March 25 report from the U.S. Department of Agriculture (USDA)—and a case in Texas where a human working with cattle was infected—has put Canadian public health experts on high aler.....»»
LA"s water supplies are in good shape: But is the city ready for the next drought?
California's second wet winter in a row has left L.A's water supplies in good shape for at least another year, but the inevitable return to dry conditions could once again put the city's residents in a precarious position......»»
Instinct for "fight or flight" may be much older than we thought
Evidence in lampreys for the presence of a rudimentary sympathetic nervous system, previously thought to be unique to jawed vertebrates, has been presented in Nature. The finding may prompt a rethink of the origins of the sympathetic nervous system,.....»»
Scientists construct organo-phosphatic shells of brachiopods
Biomineralized columns, stacked in layers like a sandwich gave Cambrian brachiopod shells their strength and flexibility 520 million years ago......»»
Researchers realize hydrogen formation by contact electrification of water microdroplets and its regulation
Direct utilization of water as a source of hydrogen atoms and molecules is fundamental to the evolution of the ecosystem and industry. However, liquid water is an unfavorable electron donor for forming these hydrogen species due to its redox inertnes.....»»
Scientists experimentally observe current-driven antiskyrmion sliding
Prof. Zhang Ying's group from the Institute of Physics of the Chinese Academy of Sciences (CAS), in collaboration with domestic universities and the Los Alamos National Laboratory in the United States, has experimentally observed current-driven antis.....»»
Scientists grow human mini-lungs as animal alternative for nanomaterial safety testing
Human mini-lungs grown by University of Manchester scientists can mimic the response of animals when exposed to certain nanomaterials. The study is published in Nano Today......»»
NASA gives green light to mission to send car-sized drone to Saturn moon
NASA’s Mars helicopter mission is now officially over, but following it is an even more complex flying machine destined to explore Saturn’s largest moon......»»
El Nino not climate change driving southern Africa drought: Study
A drought that pushed millions of people into hunger across southern Africa has been driven mostly by the El Niño weather pattern—not climate change, scientists said on Thursday......»»
NASA chief warns of Chinese military presence in space
China is bolstering its space capabilities and is using its civilian program to mask its military objectives, the head of the US space agency NASA said Wednesday, warning that Washington must remain vigilant......»»
