Phys.org / Chile declares emergency as wildfires kill at least 19
Uncontrolled wildfires tore through communities in southern Chile, leaving charred ruins in their wake and at least 19 dead, authorities said, announcing the latest toll on Sunday.
Phys.org / Exposing how humidity can escalate a heat wave
When Floridians talk about extreme weather, hurricanes dominate the conversation. Each season brings updates on storm tracks, cone predictions and wind speeds, all in the hopes of predicting the unpredictable. But a quieter, ...
Phys.org / How to prevent charge buildup in a lunar rover
As they roll across shadowed regions of the moon's surface, future lunar rovers could develop hazardous buildups of electric charge on their wheels. Through new analysis published in Advances in Space Research, Bill Farrell ...
Tech Xplore / New memristor training method slashes AI energy use by six orders of magnitude
In a Nature Communications study, researchers from China have developed an error-aware probabilistic update (EaPU) method that aligns memristor hardware's noisy updates with neural network training, slashing energy use by ...
Phys.org / Scientists uncover hidden 'winter memory' inside plants
Scientists have developed a powerful new microscope that reveals, for the first time, how plants store a 'memory' of winter deep inside their cells.
Medical Xpress / How our nasal passages defend against the common cold and help determine how sick we get
When a rhinovirus, the most frequent cause of the common cold, infects the lining of our nasal passages, our cells work together to fight the virus by triggering an arsenal of antiviral defenses.
Phys.org / COVID-era trick could transform drug and chemical discovery
Laboratories turned to a smart workaround when COVID‑19 testing kits became scarce in 2020. They mixed samples from several patients and ran a single test. If the test came back negative, everyone in it was cleared at once. ...
Phys.org / Scientists design artificial pain receptor that senses pain intensity and self-heals
All over the body are tiny sensors called nociceptors whose job is to spot potentially harmful stimuli and send warning signals to the brain and spinal cord, helping protect us from injury or tissue damage.
Phys.org / 3D mapping of fault beneath Marmara Sea reveals likely sites for future earthquakes
According to researchers from Science Tokyo, a new three-dimensional model of the fault beneath the Marmara Sea in Turkey reveals where a future major earthquake could take place. Using electromagnetic measurements, the team ...
Phys.org / Japan Trench geology confirmed as key driver of 2011 megaquake
Geologists from Heriot-Watt are part of an international research team that has confirmed why the 2011 Tōhoku earthquake off northeast Japan behaved in such an extreme and destructive way.
Phys.org / Calm seas can drive coral bleaching, research reveals
New research by Monash University and the ARC Center of Excellence for the Weather of the 21st Century analyzed close to three decades of weather data during the coral bleaching season and identified the prevalence of "doldrum ...
Medical Xpress / A new robotic system could perform delicate eye surgery
Retinal vein occlusion (RVO) is a severe disease that occurs when a vein in the light-sensitive layer at the back of the eye (i.e., the retina) becomes blocked, which results in a loss of vision. There are currently a few ...
