Learning new vocabulary during deep sleep

Researchers showed that we can acquire the vocabulary of a new language during distinct phases of slow-wave sleep and that the sleep-learned vocabulary could be retrieved unconsciously following waking. Memory formation appeared to be mediated by the same brain structures that also mediate wake vocabulary learning. Source: Learning new vocabulary during deep sleep

Effectively collecting tiny droplets for biomedical analysis and beyond

In a single sneeze or a cough, as many as 40,000 tiny droplets are forcibly propelled from our mouth and nose into the air. While we cannot control our sneezing, researchers have recently developed an original method to collect micro-droplets, such as these ‘precious’ human dewdrops, which may shed light on applications in detecting disease-causing […]

Dynamic aspirin: Molecular vibrations drive electrons over large distances

Aspirin is not only an important drug but also an interesting physics model system in which molecular vibrations and electrons are coupled in a particular way. For the first time, X-ray experiments in the ultrashort time domain make electron motions visible in real time. They demonstrate that very small atomic displacements shift electrons over much […]

Newborn babies' brain responses to being touched on the face measured for the first time

A newborn baby’s brain responds to being touched on the face, according to new research. Babies use this sense of touch — facial somatosensation — to find and latch onto their mother’s nipple, and should have this ability from birth. Premature babies often have difficulty feeding, and underdevelopment of their facial sensitivity may be one […]

Dodging antibiotic resistance by curbing bacterial evolution

Lowering mutation rates in harmful bacteria might be an as yet untried way to hinder the emergence of antimicrobial pathogens. One target for drug development might be a protein factor, DNA translocase Mfd, that enables bacteria to evolve rapidly by promoting mutations in many different bacterial species. This action speeds antibiotic resistance, including multi-drug resistance. […]

From the ashes of a failed pain drug, a new therapeutic path emerges

A surprising discovery about a failed pain drug — and specifically, the pathway it targets, BH4 — could have implications for autoimmunity and cancer. Neuroscientists report that BH4 also functions as a kind of immunological thermostat, raising and lowering the activity levels of T cells. Inhibiting BH4 could relieve atopic dermatitis, psoriasis, lupus, polyarthritis and […]
