Medical Xpress / Wearable trackers can detect depression relapse weeks before it returns, study finds
Could a smart watch act as an early-warning system for depression relapse? New research from McMaster University suggests that disruptions in a person's sleep and daily activity routine, as detected through a simple wrist-worn ...
Phys.org / Laser‑written glass chip pushes quantum communication toward practical deployment
As quantum computers continue to advance, many of today's encryption systems face the risk of becoming obsolete. A powerful alternative—quantum cryptography—offers security based on the laws of physics instead of computational ...
Medical Xpress / Sour grapes? Experience of sour food depends on individual consumer
Biting into a tart green apple is a different taste and sensory experience than sucking juice from a lemon—and both significantly vary from accidentally consuming spoiled milk. Each of these foods contains a different organic ...
Phys.org / Root microbes could help oak trees adapt to drought
Microbes could help oak trees cope with environmental change. Publishing in Cell Host & Microbe, a study observing oaks growing in a natural woodland found that the trees' above- and below-ground microbiomes were resilient ...
Phys.org / Flipping and reversing mini-proteins could improve tuberculosis treatment
Antibiotic treatments are losing effectiveness against a range of common bacterial pathogens, including E. coli, K. pneumoniae, Salmonella and Acinetobacter, according to a warning issued by the World Health Organization ...
Phys.org / Keeping an eagle eye on carbon stored in the ocean
Geologic reservoirs that trapped petroleum for millions of years are now being repurposed to store the greenhouse gas carbon dioxide. New research is improving how we monitor this storage and verify how much CO2 these reservoirs ...
Medical Xpress / Why asthma can hit women harder: Estrogen-linked IL-33 ramps up lung inflammation
Asthma affects millions of people worldwide, and adult women experience the condition more frequently—and often more severely—than men. Symptoms can also fluctuate during puberty, pregnancy and menopause, yet the biological ...
Phys.org / Supercomputer simulations test turbulence theories at record 35 trillion grid points
Using the Frontier supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers from the Georgia Institute of Technology have performed the largest direct numerical simulation (DNS) of turbulence ...
Phys.org / Bison hunters abandoned long-used site 1,100 years ago to adapt to changing climate, Great Plains study finds
On the Great Plains of North America, bison were hunted for thousands of years before populations collapsed to near extinction due to overexploitation in the late 1800s. But long before then, bison hunters used various strategies ...
Medical Xpress / Australia's food labeling system isn't working—here's how we can fix it
If you've ever read a food label and come away feeling more confused, you're not alone. Since 2014, Australian shoppers have relied on the Health Star Rating scheme to help them choose which foods to eat. This system ranks ...
Phys.org / Quantum dots reveal entropy production, a key measure of nanoscale energy dissipation
In order to build the computers and devices of tomorrow, we have to understand how they use energy today. That's harder than it sounds. Memory storage, information processing, and energy use in these technologies involve ...
Medical Xpress / Distinct resilience profiles predict psychological outcomes during adversity, study reveals
Higher self-reported levels of resilience were linked to lower anxiety and depression and better coping strategies during the COVID-19 pandemic, according to a study published in PLOS One by Joseph Anthony Pettit of Bangor ...
