Phys.org / Hubble spies ancient 'Chandelier Cluster' forming stars in two bursts
The subject of today's NASA/ESA Hubble Space Telescope image is an ancient inhabitant of our galaxy. This sparkling scene features a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Phys.org / Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials
Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...
Medical Xpress / Scientists unlock gut-healing power of fruits and nuts paired with the right gut microbes
University of Louisville researchers have discovered how a naturally occurring microbial compound may help protect the gut and support future treatment strategies for inflammatory bowel disease (IBD).
Phys.org / Natural hallucinogens may have evolved as ecological tools, not chemical accidents
Natural hallucinogens, such as psilocybin, mescaline, N,N-dimethyltryptamine (DMT) and related compounds, have generally received attention for their effects on human perception, emotion and cognition. Recently, interest ...
Phys.org / Centuries-old planktonic shell mystery solved with discovery of self-assembling proteins
Biomaterials with extraordinary properties, such as spider silk, have so far been known primarily from animals. Researchers at the University of Salzburg in Austria have now deciphered a surprising counterpart from the world ...
Phys.org / Newly described Australian ballista spider builds a spring-loaded snare to catch a single ant species
An international team of researchers has discovered a remarkable new spider species in the rainforest of North Queensland that spins an ingenious and powerful spring-actuated snare to catch a single species of ant—one ant ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Inorganic nanoscale device behaves like a single neuron, opening doors for AI and retinal implants
McGill University researchers have developed a light-detecting nanoscale structure that mimics how a neuron processes information. The neuron-like behavior emerges from the materials themselves, reducing the energy demand ...
Tech Xplore / Brain-inspired AI architecture could compute faster while using far less power
Spiking neural networks (SNNs) are artificial intelligence (AI) models inspired by how biological neurons communicate with each other. While biological neurons exchange information in the form of electrical impulses, SNNs ...
Phys.org / Warming may slow forest growth and cut carbon storage by 30%, model shows
Forests and land play an important role in absorbing carbon dioxide emissions, but current models and forecasts don't incorporate a surprising ecological discovery: Despite more available carbon, climate change and warmer ...
Phys.org / Ancient asteroid barrage may explain why early Earth had no stable continents
New research led by Curtin University and QUT (Queensland University of Technology) has revealed that repeated asteroid impacts may have been the dominant force shaping early Earth, delivering vast amounts of heat into the ...
