Medical Xpress / High risk of sleep apnea linked to poorer mental health in adults over 45
Researchers at Ottawa Hospital Research Institute and University of Ottawa found that high risk of obstructive sleep apnea was associated with approximately 40% higher odds of a composite poor mental health outcome at baseline ...
Medical Xpress / Sulfate and carbon in fine air pollution tied to higher depression risk
Long-term exposure to fine particulate matter like PM2.5 components in polluted air can not only cause respiratory diseases, but also increase the risk of depression in older people, especially in those living with preexisting ...
Phys.org / Biology-inspired brain model matches animal learning and reveals overlooked neuron activity
A new computational model of the brain based closely on its biology and physiology has not only learned a simple visual category learning task exactly as well as lab animals, but even enabled the discovery of counterintuitive ...
Phys.org / Ancient Puebloans kept macaws and parrots in great houses for ceremonial use
In a recent study, Dr. Katelyn Bishop conducted a zooarchaeological and archival data reanalysis of macaws and parrots recovered from Chaco Canyon to better understand their depositional contexts, material associations, and ...
Phys.org / Twisted light-matter systems unlock unusual topological phenomena
Properties that remain unchanged when materials are stretched or bent, which are broadly referred to as topological properties, can contribute to the emergence of unusual physical effects in specific systems.
Phys.org / Mathematicians crack cellular noise puzzle, paving path for better cancer treatment
Why does cancer sometimes recur even after successful treatment, or why do some bacteria survive despite the use of powerful antibiotics? One of the key culprits identified is "biological noise"—random fluctuations occurring ...
Phys.org / Sugar-derived crystals show stiffness approaching that of aluminum
Mucic acid crystals grown from a water-based solution achieved a record-breaking stiffness for an organic crystal.
Phys.org / Using microwave pulses to plug leaks in quantum computers makes them more reliable
Scientists have developed a new approach to correcting common quantum computing errors, which could pave the way for more reliable systems.
Phys.org / NASA's Chandra rings in the new year with the Champagne Cluster
Celebrate the New Year with the "Champagne Cluster," a galaxy cluster seen in this new image from NASA's Chandra X-ray Observatory and optical telescopes.
Phys.org / Aluminum cans are a viable alternative to bottles for red muscadine wine, new study finds
One of the main reasons wine traditionally comes in bottles is to protect its quality. Glass is nonreactive, and the cork or screw cap provides an airtight seal that prevents oxygen from spoiling the liquid. In recent years, ...
Phys.org / One of the rarest animal adaptations in the world happens in the winter in Colorado
Winter is hard, and for wildlife in Colorado, it's even harder. To survive, many species have developed adaptations over hundreds of thousands of years that allow them to weather the storms, including hibernation, thicker ...
Phys.org / What's inside Mexico's Popocatépetl? Scientists obtain first 3D images of the whole volcano
In the predawn darkness, a team of scientists climbs the slope of Mexico's Popocatépetl volcano, one of the world's most active and whose eruption could affect millions of people. Its mission: figure out what is happening ...
