Medical Xpress / Shingles vaccination associated with delayed dementia onset in older adults
Every three seconds, someone, somewhere in the world, develops dementia. The number of people living with the condition is projected to rise dramatically, doubling from 78 million in 2020 to 139 million by 2050, making dementia ...
Phys.org / A new method to search for ultralight dark matter with advanced optical cavities
Dark matter is a mysterious type of matter that does not emit, absorb, or reflect light, yet is predicted to account for most of the universe's mass. While physicists have gathered extensive indirect evidence of its existence, ...
Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Phys.org / Signs of Sir Terry Pratchett's dementia may have been hidden in his books
Signs of Sir Terry Pratchett's dementia may have been present in his writing a decade before his official diagnosis, new research has found. Researchers have examined the lexical diversity—a measure of how varied an author's ...
Phys.org / Land-intensive carbon removal requires better siting to protect biodiversity, study warns
New research looks at carbon dioxide removal—where carbon is absorbed from the atmosphere and stored—and finds that large-scale reliance on land-based methods, such as planting forests or bioenergy with carbon capture ...
Phys.org / Hypothermia risks increase in Mississippi and Tennessee with next wave of frigid temperatures
With another wave of dangerous cold heading for the U.S. South on Friday, experts say the risk of hypothermia heightens for people in parts of Mississippi and Tennessee who are entering their sixth day trapped at home without ...
Phys.org / 91-qubit processor accurately simulates many-body quantum chaos
Quantum chaos describes chaotic classical dynamical systems in terms of quantum theory, but simulations of these systems are limited by computational resources. However, one team seems to have found a way by leveraging error ...
Phys.org / A student made cosmic dust in her lab—what she found could help us understand how life started on Earth
A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed ...
Phys.org / Strategic tree planting could help Canada become carbon neutral by mid-century
A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million trees along the northern edge of the boreal forest. The paper, "Substantial carbon ...
Phys.org / New 3D map of the sun's magnetic interior could improve predictions of disruptive solar flares
For the first time, scientists have used satellite data to create a 3D map of the sun's interior magnetic field, the fundamental driver of solar activity. The research, published in The Astrophysical Journal Letters, should ...
Medical Xpress / Saline nasal spray alone resolves sleep-disordered breathing in nearly one-third of children, study finds
Investigators based at Monash Children's Hospital and Royal Children's Hospital Melbourne report that a once-daily intranasal saline spray resolved obstructive sleep-disordered breathing symptoms in nearly one-third of children ...
Phys.org / Long-period Jupiter-like exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new extrasolar planet transiting a distant star. The newfound alien world, designated TOI-6692 b, is the size ...
