Phys.org / A backyard bug repellent is derailing bumblebees' ability to navigate
In the summer, many people turn to mosquito repellents to reduce the insects' buzzing and bites. One solution that has become increasingly popular in recent years is the Thermacell device, which releases vaporized, pyrethroid-based ...
Phys.org / Dark volcanic ash has visibly reshaped Martian surface since 1976
Noticeable change on Mars often takes millions of years—but the European Space Agency's Mars Express has captured a blanket of dark ash creeping across the planet in just decades.
Phys.org / 'Bathtub ring' hints at ancient Martian ocean
Caltech researchers have identified geological features on Mars that could point to the existence of a long-dried ocean that once covered a third of the Red Planet's surface. The research was conducted by former Caltech postdoctoral ...
Phys.org / Space telescopes track nearby quasar's dramatic X-ray state transition
By analyzing the data from various space observatories, Chinese astronomers have inspected a nearby quasar designated SDSS J000532.84+200717.4. Results of the new study, published April 1 on the arXiv preprint server, shed ...
Phys.org / Researchers synthesize photosynthetic molecule found in bacteria
Researchers from North Carolina State University have successfully synthesized bacteriochlorophyll a, which is a photosynthetic pigment found in bacteria that absorbs infrared light. The work represents the first chemical ...
Phys.org / A new fruit wash removes pesticides and extends shelf life
University of British Columbia researchers have developed a natural, biodegradable wash that removed up to 96% of pesticide residue from fruit and slowed browning and moisture loss. This could mean safer apples, grapes and ...
Phys.org / Cut off from making fat, parasitic wasps lose pheromones, fail to form eggs and cannot reproduce
The Easter holidays are over and many people have once again experienced firsthand how easily sweets can be converted into fat. Parasitic wasps are also capable of converting sugar into fat—a capability that long was thought ...
Phys.org / New methods can help study the phenomenon of turbulence
In his doctoral thesis, Michael Roop develops numerical methods that allow finding physically reliable approximate solutions to nonlinear differential equations used to model turbulence.
Medical Xpress / A new depression treatment may rival electroconvulsive therapy while avoiding one of its biggest drawbacks
An international clinical trial led by researchers at the Center for Addiction and Mental Health (CAMH) and University of California San Diego School of Medicine, published in The Lancet Psychiatry, has found that magnetic ...
Phys.org / Climate impact of bottom fishing depends on where and how the seabed is disturbed
Bottom fishing can release CO₂ from the seabed, but the consequences for the climate are not straightforward. New research, published in the Journal of Applied Ecology, shows that disturbing the seabed sets in motion multiple ...
Phys.org / Birds that put more energy into parenthood age faster and die younger, research shows
In a new study, appearing in Proceedings of the Royal Society B: Biological Sciences, scientists selectively bred Japanese quails into two groups: laying either relatively large or small eggs. As the quails don't do much ...
Tech Xplore / This tough Australian seed could reshape helmets and protective gear
Researchers at NYU Abu Dhabi have uncovered the secret behind the remarkable toughness of the marri nut, the hard seed of the marri tree native to Western Australia. The nut's shell is so strong that even natural predators ...
