Spectroscopy on individual molecules — ScienceDaily

While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich (TUM) provides precise information about the interaction of individual molecules with their environment. This will accelerate the identification of efficient molecules for future photovoltaic technologies, for example. An international team led by the TUM…

Reversible liquid organic hydrogen carrier system made of simple organic chemicals — ScienceDaily

Hydrogen is a highly attractive, but also highly explosive energy carrier, which requires safe, lightweight and cheap storage as well as transportation systems. Scientists at the Weizmann Institute of Science, Israel, have now developed a chemical storage system based on simple and abundant organic compounds. As reported in the journal Angewandte Chemie, the liquid hydrogen…

A new study reveals how aligned layers of atomically thin semiconductors can yield an exotic new quantum material — ScienceDaily

A team of researchers led by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) has developed a simple method that could turn ordinary semiconducting materials into quantum machines — superthin devices marked by extraordinary electronic behavior. Such an advancement could help to revolutionize a number of industries aiming for energy-efficient electronic systems —…

Judicious use of proton pump inhibitors and antibiotics may help reduce C. difficile infections — ScienceDaily

Prior antibiotic exposure and use of acid suppressing medications known as proton pump inhibitors (PPIs) may increase the risk for hospitalized children to contract dangerous Clostridioides difficile infections, according to a study published today in Infection Control & Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America. “In pediatric patients, hospital-acquired infections…

Two DBS sites equally reduced OCD symptoms but improved distinct symptoms — ScienceDaily

Deep brain stimulation (DBS) reduces symptoms of severe obsessive-compulsive disorder (OCD) during stimulation of either the ventral capsule (VC) or anteromedial subthalamic nucleus (amSTN), according to a study in Biological Psychiatry. DBS of the regions reduced OCD symptoms to a similar extent, but produced distinct effects on specific symptoms — VC stimulation drastically improved mood,…

People track when talkers say ‘uh’ to predict what comes next — ScienceDaily

Spontaneous conversation is riddled with disfluencies such as pauses and ‘uhm’s: on average people produce 6 disfluencies every 100 words. But disfluencies do not occur randomly. Instead, ‘uh’ typically occurs before ‘hard-to-name’ low-frequency words (‘uh… automobile’). Previous experiments led by Hans Rutger Bosker from the Max Planck Institute for Psycholinguistics have shown that people can…
