Medical Xpress / Simple perception test can accurately predict success of laser surgery for age-related vision loss
Laser blended vision is a treatment for presbyopia, the natural deterioration of our ability to see things close up that develops in people 40 and older. This type of laser surgery aims to correct one eye for seeing clearly ...
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 / Shedding new light on DNA repair in early human embryos, with implications for gene editing
Treating inherited diseases is one of the greatest challenges in modern medicine. In the future, targeted gene corrections at the earliest stages of embryonic development could help prevent certain inherited diseases from ...
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.
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 / Unified framework shows thermoelectric performance depends on more than the material itself
Thermoelectric materials can directly convert heat into electricity, making them promising for recovering waste heat from factories, vehicles and other sources. They can also transport heat when an electric current is applied ...
Phys.org / Unexpected Amazon hotspot: Central north faces fastest rise in extreme heat and water stress
The central north Amazon, with extensive areas of high forest cover, natural savannas and vast, important Indigenous territories, was not previously considered the area most affected by climate change.
Phys.org / Rubin observatory peers deep into the famous COSMOS field
The COSMOS field, or Cosmic Evolution Survey Deep Field, is one of the most famous patches of the universe observed by astronomers. Located in the constellation Sextans, this region was photographed by the Hubble Space Telescope ...
Phys.org / Why do some salivary glands fail? Researchers point to hidden cell stress
For cancer patients undergoing head and neck radiation therapy, people living with Sjögren's syndrome, people with diabetes or older people, reduced saliva production and the resulting dry mouth are far more than uncomfortable. ...
Phys.org / Sea-level rise could squeeze shorebirds out of critical coastal habitat, researchers find
As sea levels rise, coastal wetlands around the world are expected to shrink—and researchers at the University of British Columbia have found this could put the world's shorebirds and their critical habitat at risk.
Phys.org / Tiny cyanobacteria may be the secret heroes of ocean carbon sequestration
A process known as the biological carbon pump (BCP) moves organic carbon from near the ocean's surface to the ocean floor. That carbon often stays there for hundreds or thousands of years, making the BCP a primary source ...
Medical Xpress / New research reveals underlying mechanisms of eye inflammation
A new study published in The American Journal of Pathology provides new evidence that immune cells enter the retina via the body's standard pathway, identifying PECAM as the gatekeeper and neutrophils as proresolving mediators. ...
