Medical Xpress / Ketamine reveals shifting brain activity patterns linked to depression improvement in older adults
Researchers at Texas A&M University's Naresh K. Vashisht College of Medicine have identified time-specific patterns of brain activity following ketamine treatment in older adults with treatment-resistant depression.
Phys.org / A galaxy with almost no stars? New Cloud-9 observations strengthen the case
Astronomers have taken one of the deepest looks yet at Cloud-9, a candidate "dark galaxy," and found no trace of stars. The paper outlining this discovery was posted to the arXiv preprint server on Aug. 21.
Phys.org / Japan's Hayabusa2 achieves first-ever laser ranging experiment with an asteroid
The Japan Aerospace Exploration Agency's (JAXA) Hayabusa2 spacecraft reached another milestone this summer, a first for space agencies. On Sunday, July 5, the probe conducted the first successful laser-ranging experiment ...
Medical Xpress / Study suggests profile of people diagnosed with ADHD and autism has changed over the past decade
A study led by the Barcelona Institute for Global Health (ISGlobal) and Aarhus University shows that children and adolescents diagnosed with attention-deficit/hyperactivity disorder (ADHD) or autism spectrum disorder (ASD) ...
Medical Xpress / Popular weight-loss drug could change how doctors treat sleep apnea
One in eight people worldwide does not get an uninterrupted night's sleep because of obstructive sleep apnea (OSA). This sleep disorder causes people to wake up suddenly when a blockage or narrowing in the upper airway prevents ...
Phys.org / Low-cost phone lessons keep children learning during emergency school closures across five countries
The COVID-19 pandemic lockdowns forced people to find ways to get things done remotely. Companies developed systems that made working from home run smoothly. Educators also had to shift to mobile phones and group video calls ...
Medical Xpress / Fat cells retain hunger signal after weight loss, potentially driving obesity relapse
Two enduring biological mysteries have remained unsolved for decades: why almost everyone who loses weight gains it back, no matter how they lost it, and why obesity passes from mother to child at rates that diet and environment ...
Tech Xplore / Humanoid robot learns to sprint and perform spin kicks using AI trained on human motion data
Humanoid robots, robotic systems with body shapes and limbs resembling those of humans, could potentially assist people with manual tasks in various real-world settings. So far, however, most of these robots can reliably ...
Medical Xpress / Wound-healing peptides curb bacterial colonization in cystic fibrosis airway models
Cystic fibrosis, one of the most common genetic diseases in Switzerland, promotes chronic bacterial infections by impairing the protective barrier of the airways. Scientists at the University of Geneva (UNIGE) have discovered ...
Phys.org / Healthy checkout policy shows promise for reducing soda sales and increasing healthy snack purchases
In March 2021, Berkeley, Calif., became the first city in the world to ban the display of sugary beverages and snacks in store checkout lanes, where candy, chocolate and soda are commonly placed to encourage impulse buying ...
Phys.org / Dogs and cats carry antibiotic-resistant bacteria also found in people, study finds
Dogs and cats may carry strains of Klebsiella pneumoniae, a potentially serious bacterium that can cause infections and is also found in humans, according to new research from Bournemouth University published in the journal ...
Phys.org / Spinons may help electrons pair along stripes in some superconductors
Superconductors are materials that carry electricity with zero resistance below specific temperatures. Many of these materials become superconducting at very low temperatures, yet some enter superconducting phases at higher ...
