Phys.org / Scientists pinpoint strategies that could stop cats from scratching your furniture
Many cat owners are familiar with torn cushions, carpets, and couches. The feline instinct to scratch is innate, but is often perceived as a behavioral problem by cat owners, and sometimes leads to interventions that are ...
Phys.org / The demonstration of vacuum levitation and motion control on an optical-electrostatic chip
The levitation of microscopic objects in vacuum and the control of their movements while they are suspended was first demonstrated several decades ago. Since then, various research groups have been working on new approaches ...
Phys.org / German scientists investigate supernova remnant SNR G309.8+00.0 at high energies
Using Spektr-RG and Fermi space observatories, German astronomers have investigated the supernova remnant SNR G309.8+00.0 in X-rays and gamma rays. Results of the new study, presented June 25 on the preprint server arXiv, ...
Phys.org / Invasive brown widow spiders found to host novel bacteria related to chlamydia
Invasive brown widow spiders across three continents were highly infected with a single strain of Rhabdochlamydia, a bacterium that is related to major pathogens of humans and animals, including chlamydia. A bite from these ...
Phys.org / Two new species of Psilocybe mushrooms discovered in southern Africa
Two new species of psychoactive mushrooms in the genus Psilocybe have been described from southern Africa, bringing the list to six known species indigenous to Africa. Psilocybe species are among the most well-known and well-studied ...
Phys.org / Aboriginal ritual passed down over 12,000 years, cave find shows
Two slightly burnt, fat-covered sticks discovered inside an Australian cave are evidence of a healing ritual that was passed down unchanged by more than 500 generations of Indigenous people over the last 12,000 years, according ...
Phys.org / NASA's Webb captures celestial fireworks around forming star
The cosmos seems to come alive with a crackling explosion of pyrotechnics in this new image from NASA's James Webb Space Telescope. Taken with Webb's MIRI (Mid-Infrared Instrument), this fiery hourglass marks the scene of ...
Phys.org / Research shows how RNA 'junk' controls our genes
Researchers at Arizona State University have made a significant advance in understanding how genes are controlled in living organisms. The new study, published in the journal Nucleic Acids Research, focuses on critical snippets ...
Phys.org / Cosmic simulation reveals how black holes grow and evolve
A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single ...
Phys.org / Infrared glow high in Jupiter's atmosphere may be dark matter particles colliding
A pair of astrophysicists with Princeton University and the SLAC National Accelerator Laboratory found possible evidence of dark matter particles colliding. In their study, published in Physical Review Letters, Carlos Blanco ...
Phys.org / New study shows mysterious solar particle blasts can devastate the ozone layer, bathing Earth in radiation for years
The remarkable aurora in early May this year demonstrated the power that solar storms can emit as radiation, but occasionally the sun does something far more destructive. Known as "solar particle events," these blasts of ...
Phys.org / True scale of carbon impact from long-distance travel revealed
The reality of the climate impact of long-distance passenger travel has been revealed in new research from the University of Leeds.
