Physicists constrain dark matter
Phys.org - 28 Mar 2019 16:10
Researchers from Russia, Finland, and the U.S. have put a constraint on the theoretical model of dark matter particles by analyzing data from astronomical observations of active galactic nuclei. The new findings provide ...
Extending Human Longevity With Regenerative Medicine
Singularity Hub - 28 Mar 2019 16:00
Lizards can regrow entire limbs. Flatworms, starfish, and sea cucumbers regrow entire bodies. Sharks constantly replace lost teeth, often growing over 20,000 teeth throughout their lifetimes. How can we translate these n...
Single Population of Stem Cells Contributes to Lifelong Hippocampal Neurogenesis: Mouse Study
Neuroscience News - 28 Mar 2019 23:59
The findings support a continuous model of neurogenesis throughout development and adulthood.
How to Cut a Car's Air Drag: More Air?
Physics Buzz - 28 Mar 2019 20:01
When you think of an aerodynamic car, what comes to mind? Smooth curves, sharp points, images of smoke streaming over surfaces in a wind tunnel--but what if we didn't have to change something's shape to help it cut throu...
We could soon make animals with cells that contain two genetic codes
New Scientist - 28 Mar 2019 20:00
Molecular machinery to make synthetic proteins has been added to human cells in the lab. Next: animals and plants with artificial factories in every cell
Nearly 100 species of frogs, toads and salamanders wiped out by fungus
New Scientist - 28 Mar 2019 20:00
The deadly disease caused by chytrid fungus is now thought to have driven nearly 100 amphibian species to extinction and contributed to the decline of over 400 more
Ferromagnetic nanoparticle systems show promise for ultrahigh-speed spintronics
Phys.org - 28 Mar 2019 18:54
In the future, ultrahigh-speed spintronics will require ultrafast coherent magnetization reversal within a picosecond--one-trillionth of a second. Spintronics centers on an electron's spin and magnetic moment in solid-st...
Shrimp claw inspires new method of underwater plasma generation
Phys.org - 28 Mar 2019 18:53
Texas A&M University researchers are looking to nature for inspiration in developing a new method of underwater plasma generation using shrimp as a model--a discovery that could provide significant improvements for actio...

Live Science - 28 Mar 2019 18:24A crucial population of lions has lost much of its genetic diversity
New Scientist - 28 Mar 2019 18:14
Lions in the important Kavango-Zambezi conservation area may be less able to adapt to climate change due to a loss of genetic variation over the past century
Why LHC physics is like 'Starcraft'
Symmetry Magazine - 28 Mar 2019 17:43
Video games and physics have more in common than you might think. Freya Blekman, a professor of physics at Vrije Universiteit Brussel in Belgium, has a special chair for when she plays Starcraft. "It's a designer chair,"...
A highly efficient rooftop solar panel based on space technology
The Economist - 28 Mar 2019 17:42
EVEN THOUGH solar panels have improved over the years they are still not very efficient at doing their job. Standard panels using silicon-based solar cells typically convert 17-19% of the sun's energy into electricity. I...
Will your next barista be a robot?
The Economist - 28 Mar 2019 17:42
GAVIN PATHROSS likes his Americano at a particular strength, with exactly 2.8 shots of espresso, an order that human baristas struggle to get right. But the baristas at Ratio, his new coffee shop in Shanghai, are anythin...
Scientists discover the chemicals behind the unique Parkinson's smell
The Economist - 28 Mar 2019 17:42
HIPPOCRATES, GALEN, Avicenna and other ancient physicians frequently used odour as a diagnostic tool. Although scent is not used nearly as often in modern medicine, it still has its place. Paramedics are routinely taught...
Whiteflies are such a pest because they hack the way plants communicate
The Economist - 28 Mar 2019 17:42
WHEN SOME plants are attacked by herbivores they fight back by producing irritants and toxins as their leaves get chewed up. Certain insects, however, can resist these defences. Among the best at doing this, and hence on...
Antidepressant prescriptions have reached 70 million in England
New Scientist - 28 Mar 2019 17:32
The number of antidepressant prescriptions dispensed in England exceeded 70 million in 2018. This is almost double the number dispensed a decade ago
Shape shifting mirror opens a vista for the future
Phys.org - 28 Mar 2019 16:50
A team of researchers from JTEC Corporation and Osaka University developed a bimorph deformable mirror that allows for precise shape modification and usage under vacuum, a world first.
Dogs can recognise the scent of someone having an epileptic seizure
New Scientist - 28 Mar 2019 16:00
Service dogs for people with epilepsy can tell when their owners are having a seizure, but we don't know how. Now an experiment suggests they can smell seizures
Studying chiral exchange drag and chirality oscillations in synthetic antiferromagnets
Phys.org - 28 Mar 2019 15:30
A quasiparticle is a disturbance or excitation (e.g. spin waves, bubbles, etc.) that behaves as a particle and could therefore be regarded as one. Long-range interactions between quasiparticles can give rise to a 'drag,'...
Physicists obtain data on particle self-organization in ultracold dusty plasma
Phys.org - 28 Mar 2019 14:57
Physicists recently investigated the behavior of particles in a dusty plasma at a temperature below 2 degrees K. The experiment showed that at extremely low temperatures, nanoclusters can form in the plasma, and the synt...
