Phys.org / Artificial light is keeping reef fish awake, and the effects may ripple across coral reefs

Artificial light spilling into coastal waters from cities, ports, roads and hotels is disrupting sleep in coral reef fish and is associated with changes in markers linked to brain health, according to a new study from Bar-Ilan ...

Phys.org / Room-temperature device synchronizes distant laser spots into single coherent 'supermode'

Researchers have demonstrated a new way to make spatially separated lasers synchronize and act as a single coherent light source—without extreme conditions or complex materials.

Phys.org / How cyanobacteria developed photosynthetic membranes over the course of evolution

A new study provides the first insights into how thylakoid membranes—the internal compartments where oxygen-producing photosynthesis takes place—emerged during evolution. By comparing the genomes of cyanobacteria with and ...

Phys.org / Cats age like humans—could studying their brains reveal healthy aging secrets?

Domestic cats age in remarkably similar ways to humans and show comparable age-related patterns of brain deterioration, according to an international collaboration among the University of Bath in the U.K., Auburn University ...

Phys.org / Arctic shipping alters cloud formation, study finds

A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region.

Phys.org / Protein-tagging technology maps a hidden communication network between organs

The body's organs are in constant communication. Fat tissue tells the liver when to store or release energy, the immune system signals localized inflammation, and thousands of proteins carry these messages to organs throughout ...

Phys.org / Insects exhibit evidence of a daily body clock for humidity

In a novel experiment at the University of Cincinnati, researchers recently isolated kissing bugs, fruit flies, mosquitoes and spider beetles in a climate- and light-controlled environment and found that they responded predictably ...

Phys.org / Four new chameleon species found on Mozambique's mountaintop 'sky islands'

Tropical rainforest patches perched on isolated granite mountains in northern Mozambique have yielded four new species of sylvan chameleons, according to a new study by Prof. Krystal A. Tolley and Dr. Werner Conradie, recently ...

Phys.org / Astronomers map a magnetic 'skeleton' funneling gas into a stellar nursery

Stars form when vast clouds of cold gas in space collapse under their own gravity. But not all gas collapses, and not all clouds form stars equally efficiently. A longstanding puzzle in astrophysics is what controls this ...

Phys.org / How solar wind forecasting will help define heliosphere's boundaries

Southwest Research Institute (SwRI) scientists are using a solar wind forecasting method combined with analytic and numerical heliosphere models to find out where the first plasma boundary of the outer heliosphere lies as ...

Phys.org / Chaotic polymer vibrations may unlock stronger, flexible thermal insulators

University of Massachusetts Amherst researchers have demonstrated a possible new avenue for developing flame-retardant and generally low-conductivity (low-heat-transfer) plastics that retain the benefits of being strong and ...

Phys.org / Using less, living better: Demand-side climate action wins public support

Climate strategies are still judged largely across two dimensions: how much they cost and how many tons of CO2 they save. A new study published in Communications Sustainability argues that this narrow lens overlooks much ...
