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 ...
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.
Medical Xpress / How dopamine-producing neurons arise in the developing brain
In a new study from Karolinska Institutet, published in Nature Neuroscience, researchers have identified the neurogenic progenitor that gives rise to dopaminergic neurons, the primary neurons affected in Parkinson's disease. ...
Medical Xpress / Blood test could help guide treatment decisions in germ cell tumors
Can fragments of tumor DNA in the blood predict whether chemotherapy will be effective? Researchers at the Princess Máxima Center investigated this question together with experts from Italy and Slovakia. They focused specifically ...
Medical Xpress / What's 'scromiting'? Here's what to know about the cannabis-related condition
Some people have described a bizarre side effect after using marijuana: uncontrollable vomiting. It's sometimes called "scromiting"—a mash-up of screaming (from intense pain) and vomiting. The medical term is cannabis hyperemesis ...
Medical Xpress / Researchers drill down on genetic profiles to guide treatment for leukemia patients
Cancer researchers are making strides in efforts to use genetic profiling to develop a more precise understanding of the response to treatment of acute myeloid leukemia (AML), a rare but aggressive blood cancer.
Phys.org / Gotland hunter-gatherer graves hint at how Stone Age families organized
A woman was buried with two children, but they were not her own. In another grave, two children were placed. They were not siblings and were more distantly related, perhaps cousins. In a new study published in the Proceedings ...
Phys.org / Prehistoric fossil poses puzzles in shark research
A newly examined prehistoric shark from the age of dinosaurs provides surprising insights into the early evolution of modern sharks. It cannot be confidently assigned to any shark order that exists today and thus calls into ...
Tech Xplore / Atom-thin ferroelectric transistor can store 3,024 polarization states
Over the past few decades, electronics engineers have been trying to develop new neuromorphic hardware, systems that mirror the organization of neurons in the human brain. These systems could run artificial intelligence (AI) ...
Tech Xplore / People are overconfident about spotting AI faces, study finds
Most people believe they can spot AI-generated faces, but that confidence is out of date, research from UNSW Sydney and the Australian National University (ANU) has demonstrated. With AI-generated faces now almost impossible ...
Medical Xpress / Oral vaccine strategy used modified bacterium to combat colorectal cancer
A research team investigating the use of the bacterium Listeria monocytogenes against colorectal cancer has discovered a way to build a modified version of Listeria as an oral vaccine to prime the immune system directly within ...
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 ...
