Phys.org / Could electronic beams in the ionosphere remove space junk?
A possible alternative to active debris removal (ADR) by laser is ablative propulsion by a remotely transmitted electron beam (e-beam). The e-beam ablation has been widely used in industries, and it might provide higher overall ...
Phys.org / Quantum encryption method demonstrated at city-sized distances for the first time
Concerns that quantum computers may start easily hacking into previously secure communications has motivated researchers to work on innovative new ways to encrypt information. One such method is quantum key distribution (QKD), ...
Medical Xpress / What to know about Nipah virus after new cases in India
Reports of new Nipah virus cases in India have raised worries about yet another deadly outbreak. Nipah is a rare virus that can cause severe brain swelling and breathing problems, and there are no approved vaccines or treatments.
Phys.org / Why snakes can go months between meals: A genetic explanation
Snakes may well be one of nature's greatest predators, capable of eating whole deer or even crocodiles, but just as impressive is that they can go months, or even a whole year, without a single meal. And now an international ...
Phys.org / JWST uncovers rich organic chemistry in a nearby ultra-luminous infrared galaxy
A study led by the Center for Astrobiology (CAB), CSIC-INTA, using modeling techniques developed at the University of Oxford, has uncovered an unprecedented richness of small organic molecules in the deeply obscured nucleus ...
Phys.org / Why supermarkets may sell more by putting fresh meals in front
Why did the rotisserie chicken cross the aisle—and end up in your shopping cart? Maybe you grabbed the container that was closest to you, or maybe you examined all of the chickens, checking dates and timestamps to see when ...
Phys.org / In Antarctica, balloon lands after 23-day search for particles from outer space
After years of work building an exquisitely sensitive instrument, University of Chicago scientists stood and watched as it flew up and out of sight into the fiercely blue Antarctic sky. Launched on Dec. 20, it would travel ...
Phys.org / Twilight action could reduce light pollution's impact on biodiversity
Professor Darren Evans and Madeleine Fabusova from the School of Natural and Environmental Science have published new research that shows that typical levels of artificial light at night can simultaneously suppress early-night ...
Medical Xpress / What is gout—and what are the early warning signs to look out for
New research indicates that a drug commonly prescribed for gout may also lower the risk of heart attack and stroke when taken at an appropriate dose.
Phys.org / Porpoises 'buzz' less when boats are nearby, underwater microphones reveal
Harbor porpoises "buzz" less when boats and ships are nearby—suggesting a drop in feeding and socializing, new research shows. The paper, published in the journal Marine Mammal Science, is titled "Seasonal and diurnal patterns ...
Phys.org / Ancient Yangtze floods linked to Shijiahe decline, new 1,000-year rainfall record shows
A new study involving researchers from Oxford's Department of Earth Sciences has finally solved the mystery of what caused the collapse of an Ancient Chinese civilization—finding that widespread flooding was to blame. The ...
Medical Xpress / Is your diet causing UTIs? Here's how it may be at fault
UTIs can be painful, and they're not something people like to talk about. But they happen often, affecting an estimated 60% of women and 20% of men in their lifetimes.
