Isolation, extreme weather, and the possible arrival of humans may have killed off the holocene herbivores just 4,000 years ago.

CTE risk, severity increases with years playing American football

 

EurekAlert! – Breaking News / 23min
The risk and severity of developing chronic traumatic encephalopathy (CTE) increases with the number of years playing American football according to a new study that appears online in Annals of Neurology. These findings reaffirm the relationship between playing tackle football and CTE, and for the first time quantify the strength of that relationship.

Another casualty of climate change? Recreational fishing

 

EurekAlert! – Breaking News / 1h
Another casualty of climate change will likely be shoreline recreational fishing, according to new research. The study finds some regions of the U.S. may benefit from increasing temperatures, but those benefits will be more than offset by declines in fishing elsewhere.

Large, long-term study suggests link between eating mushrooms and a lower risk of prostate cancer

 

EurekAlert! – Breaking News / 2h
Results from the first long-term cohort study of more than 36,000 Japanese men over decades suggest an association between eating mushrooms and a lower risk of prostate cancer.

Picoscience and a plethora of new materials

 

EurekAlert! – Breaking News / 2h
The revolutionary tech discoveries of the next few decades may come from new materials so small they make nanomaterials look like lumpy behemoths. These materials will be designed and refined at the picometer scale, which is a thousand times smaller than a nanometer. A new Yale study moves picoscience in a new direction: taking elements from the periodic table and tinkering with them at the subato

Groundbreaking method detects defective computer chips

 

EurekAlert! – Breaking News / 8min
A technique co-developed by researchers at the Paul Scherer Institut in Switzerland and researchers at the USC Viterbi School of Engineering would allow companies and other organizations to non-destructively scan chips to ensure that they haven’t been altered and that they are manufactured to design specifications without error

Rare ‘Lazarus superconductivity’ observed in promising, rediscovered material

 

300+Phys.org / 1h
Researchers from the University of Maryland, the National Institute of Standards and Technology (NIST), the National High Magnetic Field Laboratory (NHMFL) and the University of Oxford have observed a rare phenomenon called re-entrant superconductivity in the material uranium ditelluride. The discovery furthers the case for uranium ditelluride as a promising material for use in quantum computers.

Oobleck’s weird behavior is now predictable

 

500+Phys.org / 4h
It’s a phenomenon many preschoolers know well: When you mix cornstarch and water, weird things happen. Swish it gently in a bowl, and the mixture sloshes around like a liquid. Squeeze it, and it starts to feel like paste. Roll it between your hands, and it solidifies into a rubbery ball. Try to hold that ball in the palm of your hand, and it will dribble away as a liquid.

Scientists observe a single quantum vibration under ordinary conditions

 

500+Phys.org / 4h
When a guitar string is plucked, it vibrates as any vibrating object would, rising and falling like a wave, as the laws of classical physics predict. But under the laws of quantum mechanics, which describe the way physics works at the atomic scale, vibrations should behave not only as waves, but also as particles. The same guitar string, when observed at a quantum level, should vibrate as individu

Complex energies, quantum symmetries

 

100+Phys.org / 1h
In a certain sense, physics is the study of the universe’s symmetries. Physicists strive to understand how systems and symmetries change under various transformations.

A new mathematical approach to understanding zeolites

 

91Phys.org / 1h
Zeolites are a class of natural or manufactured minerals with a sponge-like structure, riddled with tiny pores that make them useful as catalysts or ultrafine filters. But of the millions of zeolite compositions that are theoretically possible, so far only about 248 have ever been discovered or made. Now, research from MIT helps explain why only this small subset has been found, and could help sci

Pressure may be key to fighting climate change with thermoelectric generators

 

24Phys.org / 14min
Pressure improves the ability of materials to turn heat into electricity and could potentially be used to create clean generators, according to new work from a team that includes Carnegie’s Alexander Goncharov and Viktor Struzhkin published in Nature Materials.
