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 / 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 / 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 / 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.
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 / 125-million-year-old fossil reveals 'pregnant' shellfish
An international team of scientists led by Dr. Graciela Delvene of the Geological and Mining Institute of Spain (CSIC) has uncovered the oldest known evidence of maternal care in shellfish, revealing that some freshwater ...
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 / 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 / How thousands of nature's longest sperm squeeze into a tiny fruit fly
When Jasmin Imran Alsous peered down her microscope lens, she expected to see chaos—a mishmash of tangled cells. She was viewing the inside of a male fruit fly's sperm storage organ, using a powerful microscope at the CCBScope ...
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 / Crashing insect populations lead to smaller tree swallows that reproduce less
Since the 1970s, the number of insects at Canada's Long Point Bird Observatory has dropped by more than 60%, according to a new study led by the University of Michigan. Because of this, today's birds are smaller and facing ...
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 ...
