Phys.org / California has lost more than half of its coastal sand dunes, first-ever assessment reveals
A study conducted by UC Santa Barbara researchers and collaborators has found that California has lost more than half of its coastal dune systems. The researchers' assessment—the first of its kind for the California coast—estimates ...
Phys.org / Experiment upends beliefs on how electrons actually behave in warm dense matter
Researchers at European XFEL, Helmholtz-Zentrum Dresden-Rossendorf (HZDR), Rostock University and other collaborating institutions have used high-precision experiments to demonstrate that the most widely used models for the ...
Phys.org / New findings challenge idea that human bodies simply got bigger and bigger over time in a steady line
The biggest jump in body size among our ancestors happened around 2–2.5 million years ago, with the appearance of Homo rudolfensis or Homo erectus/ergaster, rather than gradually across the whole human family tree.
Phys.org / Nanotube-based thermoelectrics open a new pathway to waste-heat energy conversion
Whenever someone asks ChatGPT a question, heat is generated somewhere in the server room—a data center. When an electric vehicle battery generates heat during operation, the heat must be managed continuously. Manufacturing ...
Medical Xpress / Coordinated brainstem slow waves may determine when it's time for REM sleep
Sleep is one of the most widely studied states of consciousness, known to play a role in physical recovery, the processing of memories and the regulation of immune functions. During sleep, the brain transitions between light ...
Phys.org / Women negotiate as effectively as men—but leave people happier
Men and women achieve similar economic outcomes in negotiations, but female negotiators foster stronger interpersonal relationships, which lead in turn to greater satisfaction with the result and a greater desire to negotiate ...
Phys.org / Long-dismissed gas emerges as a hidden driver of urban air pollution
Researchers from Tampere University and the University of Helsinki have identified an unexpected chemical process that may influence the formation of air pollution particles in urban environments. The study shows that nitric ...
Phys.org / Leaf-based fluorescence test speeds search for plant gene-editing targets
Gene editing of plant DNA has the potential to produce crops with increased performance and resilience, but it can take a long time to achieve these gains. To shorten this process, scientists often use screening tools to ...
Phys.org / Mosquito-borne viruses avoid killing hosts by limiting protein output, study reveals
The increase in mosquito-borne virus infections is a growing public health concern. Diseases traditionally confined to tropical or subtropical regions, like dengue or West Nile virus, are expanding their geographic scope. ...
Phys.org / Seal pups and seabird chicks are suffering in extreme weather. How can we protect them?
Extreme weather is becoming the new normal, disrupting human communities across the globe.
Medical Xpress / Erucamide molecule strengthens the eye's response to damage in retinal disease
Many conditions that cause vision loss share a common feature: the gradual breakdown of the retina, the light-sensing tissue at the back of the eye. Although scientists know some of the structural changes that ensue as this ...
Phys.org / Modeling nuclear fusion at lightning speed
As we scour and scorch the Earth for deeper wells of energy, investors and government agencies are pouring billions into nuclear fusion research. The hope is that fusion may ultimately provide a virtually limitless source ...
