Tech Xplore / A stolen-phone safeguard could disrupt home alarms and block new flagship phones
When a phone is lost or stolen, reporting it to a cellular carrier is supposed to prevent unauthorized use. Michigan State University researchers have found that weaknesses in the reporting system itself could potentially ...
Phys.org / Molecular antennae make light-activated molecular switches more sensitive
From targeted cancer treatments to self-healing materials and microscopic robots, many emerging technologies depend on molecules that can be controlled with light. Researchers at Tohoku University have now developed a way ...
Phys.org / Terbium's elusive plus-4 form emerges under ordinary lab conditions, opening possibilities for rare-earth metals
Chemists in a new study led by the University of Iowa report they have isolated and described in detail an atypical state of the rare-earth metal terbium, an advance that could expand its use in quantum technologies, including ...
Phys.org / How adoption of a new crop reshaped land use in Bronze Age Europe
A new study published in Science Advances reveals how Bronze Age communities in Central Europe adapted to changing environmental and social conditions by adopting broomcorn millet, a fast-growing, climate-resilient crop.
Medical Xpress / Psychiatrists agree on a diagnosis in only 55% of cases, international study finds
In the 1970s, psychiatric diagnoses were marked by considerable uncertainty and disagreement. Since then, organizations such as the American Psychiatric Association and the World Health Organization (WHO) have worked to develop ...
Phys.org / Chandra uncovers 'hypersoft X-ray sources' that may solve two astrophysical puzzles
Using NASA's Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one, ...
Phys.org / Beryllium signal identifies stars that have swallowed rocky planets
An international team led by researchers from the University of São Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations in ...
Medical Xpress / A burst of 'pink noise' may lead to more restorative sleep
During the day, waste products such as lactic acid and worn-out proteins build up in the brain. When we sleep at night, waves of cerebrospinal fluid (CSF) help wash away this waste, keeping the brain healthy.
Phys.org / Molecular surface design achieves over 100 million-fold tuning of porous liquid viscosity
Porous liquids combine permanent nanoscale cavities with fluidity, making them promising for applications like carbon dioxide capture, gas separation and other chemical processes. Their viscosity must be tailored to the intended ...
Medical Xpress / Can AI predict glucose changes before they happen?
Diabetes is one of the most common chronic diseases, affecting around 66 million adults in Europe—a figure projected to rise to more than 72 million by 2050. For people with type 1 diabetes, keeping glucose levels within ...
Medical Xpress / More light at night linked to changes in heart structure and function
Exposure to light at night is linked to important and potentially harmful changes in the structure and function of the heart, according to a study of more than 11,000 people published in the European Heart Journal on Thursday.
Phys.org / Africa's rocks hold ancient stories. We need better ways to document and protect them
From the Vredefort Dome in South Africa (the world's oldest and largest known meteorite impact structure) to the volcanic lakes of the Great Rift Valley in Kenya, Africa's landscapes hold some of Earth's oldest stories. Morocco's ...
