Scientists develop composite accelerometer for extreme environments
The demand for microelectromechanical systems (MEMS) resilient to harsh environments is growing. Silicon-based MEMS struggle under extreme conditions, limited by their performance at elevated temperatures. Silicon carbide (SiC) stands out as a promis.....»»
Investigating changes in extreme high-temperature warning indicators over China under different global warming levels
A research team investigated the observed and climate model projected changes in extreme high temperature warning indicators across China. They found an approximately linear increase in the intensity of extreme high temperatures exceeding 35°C and 4.....»»
Scientists pit primates against smaller-brained mammals to find out who is the smartest forager
Primates, including humans, have larger brains than most other mammals, but why? Scientists searching for the answer have long followed a trail pointing to diet—specifically fruit—as the reason for why primates evolved larger brains......»»
Scientists elucidate substrate recognition and proton coupling mechanism of transporter protein VMAT2
Vesicular monoamine transporter 2 (VMAT2) is the only transporter protein in the central nervous system that mediates the storage of monoamine neurotransmitters. It plays a critical role in mediating nerve impulse transmission and neuroprotection......»»
Scientists explore how single-atom catalysts impact water purification in advanced oxidation process
The rapid increase in global industrialization in the past centuries has resulted in the disposal of excessive toxic pollutants into the environment, seriously threatening the aquatic ecosystem and human health. Peroxymonosulfate-based advanced oxida.....»»
Speeding up calculations that reveal how electrons interact in materials
Materials scientists and engineers would like to know precisely how electrons interact and move in new materials and how the devices made with them will behave. Will the electrical current flow easily within the material? Is there a temperature at wh.....»»
Researchers create the world"s strongest ionizing terahertz radiation
Terahertz waves, known as non-ionizing radiation, can turn into ionization radiation when sufficiently many terahertz photons are focused in space and time. A team led by scientists in Korea and the U.S. has created the world's most intense terahertz.....»»
Scientists uncover a multibillion-year epic written into the chemistry of life
The origin of life on Earth has long been a mystery that has eluded scientists. A key question is how much of the history of life on Earth is lost to time. It is quite common for a single species to "phase out" using a biochemical reaction, and if th.....»»
Global activity of seafloor biodiversity mapped for the first time
A team of scientists from the U.S. and the U.K. has used artificial intelligence (AI) to map the activities of seafloor invertebrate animals, such as worms, clams and shrimps, across all the oceans of the world......»»
How killifish embryos use suspended animation to survive over 8 months of drought
The African turquoise killifish lives in ephemeral ponds in Zimbabwe and Mozambique. To survive the annual dry season, the fish's embryos enter a state of extreme suspended animation or "diapause" for approximately 8 months......»»
New research shows soil microorganisms could produce additional greenhouse gas emissions from thawing permafrost
As the planet has warmed, scientists have long been concerned about the potential for harmful greenhouse gases to seep out of thawing Arctic permafrost. Recent estimates suggest that by 2100 the amount of carbon dioxide and methane released from thes.....»»
Researchers develop high-performance blue organic LEDs based on thermally activated delayed fluorescence material
Organic light-emitting diodes (OLEDs) have become a leading display technology. The luminescent material is a core component of OLEDs. Thermally activated delayed fluorescence (TADF) materials have emerged as promising emitters for achieving high-eff.....»»
One of world"s rarest whales sighted off California coast
In an extraordinary sighting, a critically endangered North Pacific right whale was spotted off the Marin County coast on Friday, thrilling scientists......»»
Climate change caused 26 extra days of extreme heat in last year: report
The world experienced an average of 26 more days of extreme heat over the last 12 months that would probably not have occurred without climate change, a report said on Tuesday......»»
Mystery of "slow" solar wind unveiled by Solar Orbiter mission
Scientists have come a step closer to identifying the mysterious origins of the "slow" solar wind, using data collected during the Solar Orbiter spacecraft's first close journey to the sun......»»
Porous materials and machine learning provide inexpensive microplastic monitoring method
Optical analysis and machine learning techniques can now readily detect microplastics in marine and freshwater environments using inexpensive porous metal substrates. Details of the method, developed by researchers at Nagoya University with collabora.....»»
How to combat alert fatigue in cybersecurity
In this Help Net Security interview, Ken Gramley, CEO at Stamus Networks, discusses the primary causes of alert fatigue in cybersecurity and DevOps environments. Alert fatigue results from the overwhelming volume of event data generated by security t.....»»
Mexico Is So Hot, Monkeys Are Falling to Their Death From Trees
Authorities and conservation groups are investigating the deaths of dozens of howler monkeys in Tabasco, where extreme heat and land-use change appear to be threatening the vulnerable species......»»
WTF Is With the Pink Pineapples at the Grocery Store?!
Using DNA from tangerines and tobacco, food scientists have made a familiar fruit tastier—and more Instagrammable—than ever. We looked into pink pineapples so you don’t have to......»»
Secrets of sargassum: Scientists advance knowledge of seaweed causing chaos in the Caribbean and West Africa
Researchers have been working to track and study floating sargassum, a prolific seaweed swamping Caribbean and West African shorelines, and causing environmental and economic harm. The study, "Changes in holopelagic Sargassum spp. biomass composition.....»»
Black holes are firing beams of particles, changing targets over time
Black holes seem to provide endless fascination to astronomers. This is at least partly due to the extreme physics that takes place in and around them, but sometimes, it might harken back to cultural touchpoints that made them interested in astronomy.....»»
