Model can more naturally detect depression in conversations

Researchers detail a neural-network model that can be unleashed on raw text and audio data from interviews to discover speech patterns indicative of depression. Given a new subject, it can accurately predict if the individual is depressed, without needing any other information about the questions and answers. from Latest Science News -- ScienceDaily https://ift.tt/2wyZyz8

Mechanism of Marburg virus sexual transmission identified in nonhuman primates

New research elucidates the mechanism of sexual transmission of filoviruses, which have been shown to persist in the testes and other immune privileged sites. Sexual transmission of filoviruses was first reported in 1968 after an outbreak of Marburg virus disease and recently caused flare-ups of Ebola virus disease in the 2013-2016 outbreak. The team found that Marburg virus persists in seminiferous tubules and that Sertoli cells are the reservoir for the virus. from Latest Science News -- ScienceDaily https://ift.tt/2C3uMV0

Using physics to predict crowd behavior

Electrons whizzing around each other and humans crammed together at a political rally don't seem to have much in common, but researchers are connecting the dots. They've developed a highly accurate mathematical approach to predict the behavior of crowds of living creatures, using methods originally developed to study large collections of quantum mechanically interacting electrons. from Latest Science News -- ScienceDaily https://ift.tt/2PS0kQE

Countries ranked by oil production emissions

Inhibiting nuclear factor kappa B improves heart function in a mouse model of Duchenne muscular dystrophy

Researchers have uncovered an unexpected mechanism that underlies cardiomyopathy (heart failure) in Duchenne muscular dystrophy (DMD). They report that nuclear factor kappa B down-regulates calcium genes, contributing to cardiomyopathy in DMD. Furthermore, data from a mouse model show cardiomyocyte ablation of NF-kappaB rescues cardiac function. from Latest Science News -- ScienceDaily https://ift.tt/2LIuhPC

Scientists identify protein that may have existed when life began
