Medical Xpress / Erectile dysfunction drug used to treat enlarged prostate symptoms may raise glaucoma risk
An erectile dysfunction drug that is also used to treat symptoms, such as sudden urgency and frequency, associated with an enlarged prostate in men may heighten the risk of glaucoma, a serious eye condition, a large comparative ...
Tech Xplore / Noninvasive AI-based system translates brain signals into written text
Some physical injuries and neurological conditions can temporarily or permanently impair movement, leaving some people unable to speak, type on keyboards or use electronic devices. Brain-computer interfaces (BCIs), systems ...
Phys.org / Nanowires restore key functions in aging T cells
For decades, scientists have accepted that the immune system naturally weakens with age. Georgia Tech biomedical engineer and Carl Ring Family Professor Ankur Singh wasn't convinced. Then the COVID-19 pandemic made the stakes ...
Phys.org / Harvesting rainwater from rooftops could help cities stay cool and cut the number of heat wave days
Collecting rainwater from rooftops and using it to spray buildings during hot weather could help cities cut air conditioning use, lower urban temperatures and lessen the impact of heat waves, according to new research from ...
Medical Xpress / Immune-inspired public health strategy improves detection of disease-carrying insects
A disease surveillance strategy modeled on the body's immune system detected more disease-carrying insects than the traditional top-down approach, according to a study led by researchers from the Perelman School of Medicine ...
Phys.org / How simple amber lights could make nights safer for insects
Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources ...
Phys.org / Experimental drug turns cancer's favorite fuel against it
Cancer cells have a voracious appetite for sugar—using it to fuel their rapid growth. This is why many scientists have tried to develop drugs that block cancer cells' metabolism by cutting off their sugar supply.
Phys.org / As urban tree shade shrinks, mortality rises
As trees disappear from urban neighborhoods, lives may be lost with them. In a new study, Northwestern University scientists tracked death rates and fluctuations in tree canopy cover across an 11-year period in Chicago. They ...
Tech Xplore / Hardware-aware framework accelerates large language models without additional training
As large language models (LLMs) become increasingly embedded in chatbots, virtual assistants, translation services, coding tools and other AI-powered applications, delivering responses quickly and efficiently has become a ...
Medical Xpress / A 'molecular switch' that heals the gut—and that colorectal cancer hijacks to spread
Digestion is hard on the cells that line the human gut, and they are constantly being shed and replaced. This renewal is driven by a population of tireless stem cells. These stem cells can both replace the various types of ...
Phys.org / Electric field reverses phonon chirality and spin direction in ferroelectric crystal
Chiral phonons are groups of atoms that move in a circular direction when excited by an energy source, such as heat. As the phonons move through a material, they propagate that circular motion, or angular momentum, through ...
Phys.org / Melting sea ice combines with Arctic sea to make clouds
Scientists have uncovered a previously unknown natural process that dramatically increases the number of cloud-forming particles in the Arctic atmosphere—potentially altering cloud cover, sunlight reflection and future climate ...
