Phys.org / Warming may make tropical cyclone 'seeds' riskier for Africa
An existing body of research indicates that climate change is making tropical cyclones wetter and more powerful. Now, a new study is indicating the same thing may be happening to the precursors of these storms: the wet weather ...
Phys.org / The sound of droplets striking water: How cowbirds control two sound sources in the syrinx to create 'liquid notes'
Cowbirds are special among songbirds for the "watery" timbre of their singing, which resembles the sound of falling droplets striking water, a quick burst followed by a fading ripple.
Phys.org / Simulations explore Neanderthal and modern human encounters in ancient Europe
Using a specially developed simulation model, researchers at the University of Cologne have traced and analyzed the dynamics of possible encounters between Neanderthals and anatomically modern humans on the Iberian Peninsula ...
Phys.org / PFAS concentrations can double with every step up the food chain
A new UNSW-led global meta-analysis shows that PFAS concentrations can double at every step up the food chain, leaving top predators—and humans—potentially exposed to higher chemical loads.
Phys.org / AI mimics human-like intuition to explore and analyze chemical reactions
Chemical reactions are the breaking and forming of chemical bonds, which are fundamental to the creation of new technologies. Inevitably, discovering and developing new chemical reactions is a time-intensive process of trial ...
Phys.org / Artificial metabolism turns waste CO₂ into useful chemicals
In a breakthrough that defies nature, Northwestern University and Stanford University synthetic biologists have created a new artificial metabolism that transforms waste carbon dioxide (CO2) into useful biological building ...
Phys.org / Mixing incentives and penalties found key to cutting carbon emissions long term
A study from a team of researchers that includes faculty from the University of California San Diego and Princeton University shows how a mix of subsidies for clean energy and taxes on pollution can significantly reduce greenhouse ...
Phys.org / Ancient sea anemone sheds light on animal cell type evolution
One of the biggest quests in biology is understanding how every cell in an animal's body carries an identical genome yet still gives rise to a kaleidoscope of different cell types and tissues. A neuron doesn't look nor behave ...
Phys.org / Scientists who use AI tools are publishing more papers than ever before
Science is entering a massive publishing boom, in large part due to artificial intelligence. New research published in the journal Science has revealed that scientists who use large language models (LLMs) like ChatGPT are ...
Dialog / Cosmic rays from a nearby supernova may help explain Earth-like planets
How common are Earth-like planets in the universe? When I started working on supernova explosions, I never imagined that my research would eventually lead me to ask a question about the origin of Earth-like planets. Yet that ...
Phys.org / Controlling exciton flow in moiré superlattices: New method leverages correlated electrons
Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition ...
Phys.org / Paraplegic engineer becomes the first wheelchair user to blast into space
A paraplegic engineer from Germany blasted off on a dream-come-true rocket ride with five other passengers Saturday, leaving her wheelchair behind to float in space while beholding Earth from on high.
