Phys.org / Physicists test the weak equivalence principle in an orbiting space station
The weak equivalence principle (WEP) is central to Einstein's general relativity. It posits that gravity must accelerate everything equally, regardless of what it is made from. For the first time, a team led by Ming-Sheng ...
Phys.org / Crash in dugong population estimates, a warning sign governments can't ignore
A 50% decline in the Gulf of Carpentaria dugong population estimate is a wake-up call for urgent action to protect dugongs in the Gulf, based on surveys undertaken by researchers from James Cook University, Charles Darwin ...
Medical Xpress / Scientists discover how fructose may help drive obesity
High-fructose corn syrup is just one of many food additives linked to obesity. It is typically found in sweetened beverages and processed foods and is added to enhance flavor and sweetness. However, exactly how it contributes ...
Phys.org / Giant impact could have formed an intact moon within five hours, simulations suggest
New Southwest Research Institute (SwRI) modeling, conducted in collaboration with scientists at the University of Arizona, shows fundamental differences in how the moon may have formed from the giant impact that created the ...
Phys.org / Sorry, this neutrino laser won't work, physicists say
Neutrinos are pervasive yet intangible particles that permeate the universe, streaming through whole planets, stars and our bodies by the trillions each second. The elementary particles are often described as "ghostly" for ...
Phys.org / One unexplained event could hint at heavy dark matter
An unexplained signal detected by the world's most sensitive dark matter experiment could mark a major breakthrough in the hunt for the elusive substance, according to an analysis involving scientists from the University ...
Phys.org / Interstellar travel V: Warp drives, wormholes, and halo drives
Welcome back to our series on Interstellar Travel, where we look at the many proposals made for sending missions to the stars since the dawn of the Space Age. In our first installment, we examined how Cold War-era developments ...
Phys.org / Weak sea-surface temperature gradients may fuel stronger tropical cyclones
The fact that the ocean gets colder as you go deeper is fairly intuitive, but a similar gradient exists along the surface of the ocean, even at scales of 1 kilometer to tens of kilometers. A new study, published in the Proceedings ...
Phys.org / More than 120 molecular species found in giant cloud near Milky Way's center
Astronomers have discovered a second interstellar cloud near the center of the Milky Way that is extraordinarily rich in complex molecules, including several molecules associated with prebiotic chemistry. The newly studied ...
Medical Xpress / How cannabis legalization affects substance use
The legalization of cannabis affects substance use, with the potential for both negative and positive effects on public health, a new McGill-led study found.
Medical Xpress / Scientists uncover shared biology behind profound fatigue in five major illnesses
A shared biological mechanism that helps explain chronic exhaustion in conditions including long COVID and PTSD has been identified by researchers at the University of East Anglia and Oxford BioDynamics. The paper, published ...
Phys.org / When biology inspires mathematics: Hidden symmetries explain why widely used evolutionary methods can give false answers
Why do some groups of organisms contain thousands of species while others have only a handful? Evolutionary biologists have spent decades trying to answer this question using mathematical models that estimate how biological ...
