We all know the feeling: the mental clarity that comes after a good run or a heavy workout. Science backs this up, even showing that for non-severe depression, exercise can be just as effective as antidepressants or therapy. ...
Medical Xpress / Macrophages need constant reminders to retain memories of prior infections, researchers discover
Researchers from the University of California, Los Angeles, have discovered that immune cells known as macrophages remain poised to fight repeat infections due to the persistent presence of signaling molecules left behind ...
Phys.org / How one molecule's 'voice' was captured: Infrared light meets scanning tunneling microscopy
When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region of the electromagnetic ...
Medical Xpress / What is ALS, the disease that killed actor Eric Dane?
Eric Dane, known for his roles on "Grey's Anatomy" and "Euphoria," died this week from amyotrophic lateral sclerosis at age 53.
Medical Xpress / Big data and human height: Scientists develop algorithm to boost biobank data retrieval and analysis
Extracting and analyzing relevant medical information from large-scale databases such as biobanks poses considerable challenges. To exploit such "big data," attempts have focused on large sampling algorithms that model individual ...
Phys.org / New nanohole-based microscopy monitors electrochemical reactions millisecond by millisecond
Many technological applications, such as sensors and batteries, greatly rely on electrochemical reactions. Improving these technologies depends on understanding how electrochemical reactions work. However, most current methods ...
Phys.org / Leadership is the bedrock of real green culture, new research shows
New research shows that employees are far more likely to act in environmentally responsible ways when their leaders actively demonstrate green values in how they lead, not just what they say. The study, published in the Journal ...
Medical Xpress / Evidence suggests chatbot disclaimers may backfire, strengthening emotional bonds
Concerns that chatbot use can cause mental and physical harm have prompted policies that require AI chatbots to deliver regular or constant reminders that they are not human. In an opinion appearing in Trends in Cognitive ...
Medical Xpress / Fueling for gold: How nutrition impacts strength, speed, and recovery in Olympic athletes
If our bodies are machines and food is fuel, it is safe to say that elite performance requires high-octane nutrition. As the Winter Olympics continue in Italy, the world watches as top athletes display the highest capabilities ...
Phys.org / Intensive grazing and soil fertility favor the growth of non-native plants, drylands study finds
A global study has revealed the conditions under which non-native plants thrive in the world's many dryland regions and the factors that limit their spread. Using data from 98 study sites across 25 countries on six continents, ...
Phys.org / Terahertz spectroscopy finds nitrogen can lengthen GaAs-like LO phonon decay
An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the effects of dilute nitridation.
