Medical Xpress / New study finds eye focuses using color signals, not just sharpness
The human eye functions like an exceptionally precise, high-end camera, one with a resolution of around 576 megapixels. What makes it intriguing is that although our eyes can focus on light at only one wavelength at a time, ...
Medical Xpress / Skin can 'pre-learn': Priming cells for regeneration before injury
It is well known that students who prepare in advance perform better in exams. Now, it appears that the skin can do the same. Rather than scrambling to repair itself only after injury occurs, a Korean research team has demonstrated ...
Phys.org / Momentum-engineered photonic states make bulk silicon shine
An international team of researchers, led by scientists from the University of California, Irvine, has demonstrated a fundamentally new way to make silicon emit light—overcoming one of the most persistent limitations in modern ...
Medical Xpress / Why anti-cancer drugs do not always live up to expectations
For more than a decade, a class of drugs called BET inhibitors has been tested in cancer trials with high expectations. The biology looked promising. Many cancers depend on oncogenes that "Bromo- and Extra-Terminal domain" ...
Medical Xpress / Study identifies why nightmares persist in children and how to break the cycle
Research from the University of Oklahoma and the University of Tulsa proposes a new model to explain why nightmares can persist over time in children and how therapy can be designed to break that cycle.
Medical Xpress / Little-used cholesterol test could prevent more heart attacks and strokes
A routine blood test taken by millions in the U.S. each year to measure "bad" cholesterol is not the best measure to guide treatment and prevent heart attacks and strokes, suggests a new Northwestern Medicine study published ...
Phys.org / Soundscapes from nearby forests are more uplifting than those from faraway places, research suggests
Listening to one-minute-long audio recordings of forests had positive effects on people's short-term well-being, especially when the recordings were from local temperate forests. Study participants residing in Germany perceived ...
Phys.org / 'Oldest octopus' fossil is no octopus at all, scans reveal
A famous 300-million-year-old fossil that was thought to be the world's oldest octopus—even featuring in the Guinness Book of Records—has turned out to be something else altogether. In what amounts to a case of mistaken identity, ...
Phys.org / A 'stemness checkpoint' helps control stem cell identity
A study published in Cell Research advances a central idea in stem cell biology by identifying a checkpoint that controls the identity of many different types of stem cells across developmental stages. For nearly two decades, ...
Phys.org / Satellites capture the volatile human–luminescence relationship
From space, Earth's populated areas glow on the otherwise "black marble" of the planet at night. For decades, scientists assumed this glow was steadily increasing as the world developed. However, a new study published in ...
Phys.org / Plastic bags to gasoline: Molten salts crack polyethylene into real fuels
Researchers at the Department of Energy's Oak Ridge National Laboratory developed a method to convert a commonly discarded hydrocarbon polymer into gasoline- and diesel-like fuels. The team has applied for a patent for the ...
Phys.org / Ancient tectonic processes are the key to locating rare minerals
New research from Adelaide University has revealed that geological processes dating back billions of years are critical to locating the rare earth elements needed for modern technologies and the global clean energy transition. ...
