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 ...
