Tech Xplore / No power, no phone, no radio: Why comms dropped out during the Central Victorian fires
Australia has entered an era of climate instability, where communications during bushfires and extreme weather must perform under increasingly severe conditions.
Phys.org / Millions of working horses and donkeys face health risks from poor harnessing
These days, the mention of a carthorse or mule plowing a field would transport many people back in time to an era of horse-drawn carriages and pre-industrial agriculture.
Phys.org / Sinking boreal trees in the deep Arctic Ocean could remove billions of tons of carbon each year
Global efforts to reduce pollution will not be enough to mitigate the worst effects of climate change, scientists say. We will also need to extract over 10 gigatons of carbon dioxide from the atmosphere every year for the ...
Phys.org / Researchers solve mystery of universe's 'little red dots'
Since the James Webb Space Telescope (JWST) went into operation, red dots in its images have puzzled researchers around the world. Now, researchers from the University of Copenhagen have explained these enigmatic findings, ...
Medical Xpress / Ghana collects half the blood it needs—digital approaches can improve that
It is late, the ward is crowded, and the clock is moving faster than everyone would like. A doctor has stabilized the patient as best they can, but one thing is missing—blood.
Phys.org / Wormholes may not exist—we've found they reveal something deeper about time and the universe
Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen.
Phys.org / Fluid gears rotate without teeth, offering new mechanical flexibility
A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The invention holds potential for a new generation of mechanical devices that offer greater flexibility and ...
Phys.org / Complex life on planets orbiting the galaxy's most common stars may be unlikely
In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy.
Phys.org / NASA's new moon rocket moves to the pad ahead of astronaut launch as early as February
NASA's giant new moon rocket moved to the launch pad Saturday in preparation for astronauts' first lunar fly-around in more than half a century.
Phys.org / Plastic pellets known as 'nurdles' are polluting beaches and waterways
Aboard an aluminum skiff or one of her five kayaks, fourth-generation shrimper and fisherwoman Diane Wilson often plies the coastal bays and streams near her tiny hometown of Seadrift, Texas.
Phys.org / Enthusiasts used their home computers to search for ET—scientists are homing in on 100 signals they found
For 21 years, between 1999 and 2020, millions of people worldwide loaned UC Berkeley scientists their computers to search for signs of advanced civilizations in our galaxy.
Phys.org / New state of matter discovered in a quantum material
At TU Wien, researchers have discovered a state in a quantum material that had previously been considered impossible. The definition of topological states should be generalized.
