Medical Xpress / Why do falls rise with age? Study points to cerebellar neuron firing
A new McGill University study has found a direct link between age-related declines in neuron activity in the cerebellum and worsening motor skills, including gait, balance and agility. While it is well known that these abilities ...
Phys.org / System isolates single extracellular vesicle surface proteins to map function
Extracellular vesicles (EVs) are tiny biological bubbles that carry nucleic acids and proteins between cells, playing an essential role in tissue repair, neuroprotection and immune health. By isolating the surface proteins ...
Phys.org / Young 'sun' caught blowing bubbles by Chandra
For the first time, a much younger version of the sun has been caught red-handed blowing bubbles in the galaxy by astronomers using NASA's Chandra X-ray Observatory. The bubble—called an "astrosphere"—completely surrounds ...
Phys.org / Turning high-emissions waste into fertilizer: Catalyst boosts urea production by coupling CO₂ with nitrogen pollutants
UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer without the intensity of emissions associated with fossil-fuel-powered factories. The solution is outlined ...
Phys.org / Why the planet doesn't dry out all at once: Scientists solve a global climate puzzle
Researchers at the Indian Institute of Technology Gandhinagar (IITGN), in collaboration with international partners, have shown that ocean temperature patterns help limit the global spread of droughts. Published in Communications ...
Phys.org / Sunray-like ripples emerge on a frozen reaction front
Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review Letters, Anne De Wit and colleagues ...
Phys.org / Alloy-engineered valleytronics: Microscopic mechanism gives scientists precise control over how excitons behave
Scientists have observed a new microscopic mechanism enabling precise control of the magneto-optical properties of excitons in alloys of two-dimensional semiconductors. This discovery opens up tangible prospects for technological ...
Phys.org / Between the Pampa and Patagonia: New clues about how ancient hunter-gatherers fed themselves
An archaeological study reveals how ancient hunter-gatherer groups lived—and survived—more than a thousand years ago in the transition zone between the Pampas and Patagonia in Argentina. The research, carried out by Martínez ...
Phys.org / Peatland lakes in Congo Basin release carbon that is thousands of years old
Researchers at ETH Zurich have now discovered for the first time that large blackwater lakes in the extensive peatlands of the central Congo Basin are releasing ancient carbon. To date, climate researchers had assumed that ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Phys.org / The legal void of the asteroid gold rush
Asteroid mining companies are finally getting off the ground, and that is raising some concerns about the impact those activities will have on the space environment. A new paper published in Acta Astronautica by Anna Marie ...
Medical Xpress / How physical activity may help cancer survivors live longer
Staying fit and active has long been associated with better heart and overall health. It might also improve the chances of survival for people with some forms of cancer. A study published in the journal JAMA Network Open ...
