Phys.org / Hyperdoped silicon photodiode advances short-wave infrared detection at room temperature
Detecting short-wave infrared (SWIR) light, a region of the electromagnetic spectrum just beyond the light visible to the human eye, could be advantageous for many real-world applications. For instance, it could enable more ...
Phys.org / Setting limits on phase transitions in the dark energy era
The universe is known to be expanding at an accelerating rate. Physicists typically attribute this acceleration to dark energy, a mysterious component of the universe that exerts negative pressure, causing space to expand ...
Tech Xplore / Aurivillius-type materials could lower the operating temperature of fuel cells
Fuel cells, devices that generate electricity by converting the chemical energy of hydrogen or other fuels via electrochemical reactions, are promising solutions for powering large electric vehicles, industrial sites and ...
Medical Xpress / Male sex hormones may protect lungs from asthma by boosting nerve connections
The differences in male and female sex hormones are most evident during growth, puberty and reproduction, when they help shape how the body develops and functions. Beyond their more visible effects, these chemical messengers ...
Phys.org / The little red dots of our cosmos might hide something big
Little red dots may reside in small, dense galaxies with total masses equivalent to around 1 billion times that of the sun, according to research published in Nature Astronomy.
Phys.org / Utah mountain ranges may store a billion tons of hidden ice
Unlike conventional glaciers, rock glaciers appear as piles of rock that obscure large masses of unaccounted-for ice. Rock glaciers are common in the Wasatch and Uinta ranges, even appearing on the Colorado Plateau in the ...
Phys.org / Engineered yeasts help turn PET plastic and crop waste into protein-rich cookies
Plastic might be the last ingredient you would ever add to a cookie recipe. But a team of researchers is looking to change that. They've programmed yeasts to turn plastic and agricultural waste into edible proteins and flavoring ...
Phys.org / One molecule, one photon: Entanglement makes an imperceptible recoil measurable
For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at ...
Medical Xpress / Heart capillaries may build natural bypasses for blood flow after heart attacks
The heart powers a busy highway of arteries and vessels, providing a constant to-and-fro passage for blood. During a heart attack, this passage becomes blocked, usually when a blood clot forms on plaque in a coronary artery ...
Phys.org / Why some lava-covered exoplanets retain atmospheres for billions of years
Stanford researchers have offered an explanation for why some sizzling, lava-covered worlds nestled tightly around their stars can retain their atmospheres. At such close quarters, intense stellar radiation should strip away ...
Phys.org / Narrow ultrasonic beam enables stable 3D levitation six times farther than before
Scientists have developed a new acoustic levitation technique using an ultrasonic beam capable of levitating and moving small objects in midair over distances of up to 40 cm (16 inches), six times farther than previously ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
