In Drosophila erecta, food volatiles trigger male sexual arousal and start a visual feedback loop across the group. D. melanogaster does not depend on them for courtship.
Researchers at the Chinese University of Hong Kong compared stool microbiomes of 720 children with ASD and 151 controls. Associations with severity were significant but explained little variance.
Ferroelectric transistors on wurtzite AlScN with an ultrathin IGO channel reached a 20.6 V memory window, 10^6 endurance and 64 states. The MFMIS structure lowered interface trap density.
Repeated binge alcohol in APP/PS1 mice, a model of Alzheimer's disease, caused liver injury and raised inflammatory markers in liver and brain. The authors link this to vesicles from hepatocytes.
Dynamic ultrasound plus MRI segmented compartments of the flexor digitorum superficialis in vivo and gave 3D fiber trajectories; the study involved ten healthy people.
Peking University researchers found that old mice have fewer grid cells and less stable spatial coding, and fewer Bglap3+ layer III neurons in the medial entorhinal cortex.
Authors built age-based reference volumes of the hippocampus and its subfields and used them to score individual patients with five neurological disorders.
Profiling of cerebrospinal fluid and plasma identified three autoantibodies, one to alpha-crystallin B that prefers phosphorylated serine-45. Authors do not define a new disease.
Dutch groups ran a massively parallel reporter assay in human neural stem cells to find which non-coding SNPs can affect transcription, a problem for GWAS because of linkage disequilibrium.
Neuroscientists at Emory University detected a sixfold-symmetry signature in the ventromedial prefrontal cortex as 18 participants evaluated emotional stimuli. The sample is small; the role of the pattern is not established.
Nature Communications study from the University of Padua: the enzyme thrombin truncates α-synuclein, a protein linked to Parkinson's disease, in vitro and in a complex biological medium.
Authors report that cold activates TH-positive nerve fibers in the lung, which lowers SCGB3A1 expression in Club cells and promotes thermogenesis in adipose tissue of mice.
Italian CNR-Nanotec researchers and partners made organic artificial synapses from a PEDOT:PSS:Nafion polymer system; the lab devices respond to dopamine and have eight tunable states.
