Phys.org / Gravitational waves as possible candidates for the origin of dark matter
Gravitational waves could be responsible for the production of dark matter during the early phases of our universe's formation, according to results of a new study by Professor Joachim Kopp from Johannes Gutenberg University ...
Phys.org / Oregano, rosemary and 'time': Long-term swine study shows natural-compound benefits
In the search to replace antibiotic growth promoters with effective alternatives in modern swine production, plant-based essential oils are showing potential to provide lasting benefits. In a rare long-term public study that ...
Phys.org / FAST observes a peculiar rotating radio transient that also switches to pulsar states
Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), Chinese astronomers have explored the behavior of a rotating radio transient (RRAT) known as RRAT J1574+4703. The new observations found that this object ...
Phys.org / Reducing aircraft soot might not actually reduce the climate effects of contrails
Reducing aircraft soot emissions may not reduce contrail clouds, according to in-flight observations of emissions from a passenger jet with modern "lean-burn" engines, reported in Nature. Contrails from aircraft contribute ...
Phys.org / Why subduction zones act as the Earth's 'gold kitchens'
Earth's "gold kitchen" lies deep beneath the seafloor. Island arcs, whose volcanoes form above subduction zones where one oceanic plate sinks beneath another, are often particularly rich in gold. The reasons for this have ...
Phys.org / Fins, fingers and toes: A new take on repeating body parts and how they come to be
As biologists know, nature can take its sweet time explaining itself. Andrew Gillis, associate scientist at the Marine Biological Laboratory (MBL), has been investigating how the paired fins of fishes evolved for nearly 20 ...
Phys.org / Superconductivity switched on in material once thought only magnetic
Superconductivity—the ability of a material to conduct electricity without any energy loss to heat—enables highly efficient, ultra-fast electronics essential for advanced technologies such as magnetic resonance imaging (MRI) ...
Phys.org / Hidden features in X-rays could radically change how we measure and understand them
Hidden features uncovered in X-ray signals are set to overturn a key scientific theory and fundamentally change how X-rays are interpreted across fields of physics, chemistry, biology and materials science, new research reveals. ...
Phys.org / Chaos shapes how meandering rivers change over time, research shows
Rivers are rarely the calm, orderly streams we imagine on maps. Over time, their winding paths—called meanders—shift, bend, and occasionally snap off in sudden "cutoff" events that shorten loops and reshape the landscape. ...
Phys.org / Free software lets laptops simulate how aging evolves under selection
Why do some species live for only weeks while others survive for centuries? Researchers at the Leibniz Institute on Aging—Fritz Lipmann Institute (FLI) in Jena have developed AEGIS, a freely available software tool that enables ...
Phys.org / Stretching metals can tune catalysis: A new method predicts energy shifts
Heterogeneous catalysis—in which catalysts and reactants are of different phases, e.g., solid and gas—is important to many industrial processes and often involves solid metal as the catalyst. Ammonia synthesis, catalytic ...
Phys.org / How gossiping mushroom networks share your public urination secrets
Psst, have you heard that mushrooms can "gossip" and spread information to their neighbors? Underneath the umbrella-like shapes we see on the forest floor is a hidden underground network that allows mushrooms to communicate. ...
