Medical Xpress / Cannabis and tobacco use linked to smaller brain volume
Cannabis and tobacco—whether used on their own or together—can affect the brain's structure. A recent study involving systematic review and meta-analysis of more than 103 studies found that both substances are linked to reduced ...
Tech Xplore / Helping resolve quantum computers' memory problem
A major problem with quantum computers is memory, as the information they contain can be quickly lost. Quantum computers are not yet fully reliable—they are far too unstable. However, all around the world, people are trying ...
Phys.org / SimCells successfully target and kill drug-resistant bacteria
We are continually in an evolutionary arms race with bacteria. As we develop new antibiotics, they develop resistance, and so it goes on until some of our treatments no longer work. Superbugs and antimicrobial resistance ...
Medical Xpress / Novel technique for measuring blood flow restriction shows promise
A novel, minimally invasive method of determining whether fatty deposits in a coronary artery are restricting blood flow to a patient's heart performed similarly to the standard, more-invasive procedure in a large multicountry ...
Phys.org / Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based ...
Phys.org / New disk-shaped catalyst turns carbon dioxide into methanol at lower temperatures
Low-temperature CO2 hydrogenation might have sounded almost paradoxical until a recent study made it possible. Researchers have designed new catalysts that can transform the greenhouse gas into methanol at temperatures ranging ...
Medical Xpress / Interventions for self-harm are less effective for men, study shows
Researchers at City St George's, University of London have found that psychological interventions for self-harm appear to be more effective for females than males, raising concerns about how well current treatments meet the ...
Tech Xplore / Combining the robot operating system with LLMs for natural-language control
Over the past few decades, robotics researchers have developed a wide range of increasingly advanced robots that can autonomously complete various real-world tasks. To be successfully deployed in real-world settings, such ...
Medical Xpress / When is it time to see a doctor for joint pain?
As we move into spring, it's common for people to increase their daily movement with activities like outdoor walks, yard work, pickleball and race training. Soreness is a normal result, but sometimes lingering pain can be ...
Medical Xpress / Smart sensor decodes fatigue and stress from body signals on the move
About one in three employees in Singapore report feeling burnt out—one of the highest rates globally. Burnout and chronic fatigue carry a substantial economic cost and pose serious risks in professions where alertness is ...
Phys.org / Artemis astronauts to study the moon's surface using mainly their eyes
More than 50 years after humans first flew around the moon, Artemis astronauts will repeat the feat on Monday and use the most basic instrument to study it: their eyes.
