Phys.org / Small-plane fuel raises lead levels up to sevenfold near Oregon airports, study suggests
Emissions from aircraft that use leaded aviation gasoline are a significant source of environmental pollution in neighborhoods near regional airports, according to a new study by researchers at Oregon State University and ...
Phys.org / Global warming will exceed limit, UN says in a report that maps path to get back below danger zone
In a strategic retreat in the fight against climate change, the United Nations has acknowledged that Earth has lost its chance to prevent some of the worst of global warming's harms. So now the world must figure out how to ...
Phys.org / Surprising ingredients suggest ancient Egyptian paint was far more complex than previously assumed
Ancient Egypt has left us a wealth of artistic treasures, including wall paintings, wooden coffins and limestone reliefs. Many retain their vibrant colors despite the passage of time, a testament to the ingredients used to ...
Phys.org / Peptides can form well-defined structures in harsh, Venus-like conditions
When exploring solar system bodies for signs of past or present life, scientists have mainly focused on planets that have (or had) a liquid surface similar to Earth's. However, mounting evidence suggests that the ingredients ...
Phys.org / Wind damage can trigger years of forest vulnerability
Windstorms are among the most important natural disturbances in Northern Europe, where they cause extensive tree mortality, timber losses and long-lasting changes in forest structure. Large-scale windstorm damage has increased ...
Medical Xpress / Computer vision 'sees' our organs age at different rates
We tend to think of age as a linear progression marked by birthdays and milestones dictating when we can vote, drink, rent a car or pass beyond the crest of an arbitrary metaphorical hill. When scientists look at how organs ...
Medical Xpress / Could skin reveal new clues about aging and frailty?
When it comes to aging skin, scientists think of much more than wrinkles. They think of an organ with multitudes of microbes, immune cells, structural proteins and chemical signals that constantly interact with one another.
Medical Xpress / Understanding the neural processes underlying limb apraxia
Limb apraxia is a neurological disorder that can occur after damage to the brain's left hemisphere and is characterized by difficulty using tools despite normal motor control and cognition. It affects roughly a quarter of ...
Medical Xpress / New mechanism shows how immune cells fine-tune adhesion during infection and recovery
Researchers at the University of Liverpool helped uncover how the body adapts its immune defenses during periods of increased demand, such as infection, inflammation and recovery following stem cell transplantation.
Medical Xpress / Berry compound reduces fat buildup in muscle cells, study finds
Ectopic lipid accumulation in skeletal muscle is a major health concern driven by factors like high-fat diets, lack of exercise and aging. Unlike subcutaneous fat, these intracellular lipid droplets interfere with normal ...
Phys.org / Manganese's emission lines shine a light on galactic evolution
In a new study, a team of astronomers has identified wavelengths of light that could be useful for tracing the chemical evolution of the universe. Using computational modeling to simulate how electrons interact with manganese ...
Phys.org / Antarctica is home to microbes found nowhere else on Earth
Scientists have often wondered about species that are unique to Antarctica. But the focus has mainly been on animals, like feathery penguins. CIRES researchers wanted to dig deeper—into the soils—believing tiny organisms ...
