Heavier stars might not explode as supernovae, just quietly implode into black holes
A supernova is a brilliant end to a giant star. For a brief moment of cosmic time, a star makes one last effort to keep shining, only to fade and collapse on itself. The end result is either a neutron star or a stellar-mass black hole. We've generally thought that all stars above about 10 solar masses will end as a supernova, but a new study suggests that isn't the case.

Nature Communications, Published online: 06 September 2021; doi:10.1038/s41467-021-25616-1 Adipose tissue is composed of a number of adipocytes and a number of other cells including immune cells. Here the authors use single-cell sequencing of murine brown adipose tissue immune cells and describe multiple macrophage and monocyte subsets and show that monocytes contribute to brown adipose tissue ex

Conformational dynamics linked to domain closure and substrate binding explain the ERAP1 allosteric regulation mechanism
Nature Communications, Published online: 06 September 2021; doi:10.1038/s41467-021-25564-w The endoplasmic-reticulum aminopeptidase ERAP1 processes peptides for antigen presentation. Here, the authors assess ERAP1 conformational states in solution, providing insight into the molecular mechanisms of ERAP1 substrate-length dependent catalytic activity and regulation, including the effects of autoim

Small-molecule suppression of calpastatin degradation reduces neuropathology in models of Huntington's disease
Nature Communications, Published online: 06 September 2021; doi:10.1038/s41467-021-25651-y Mitochondrial dysfunction is a common hallmark of neurological disorders. Here, the authors identify CHIR99021 as a potent enhancer of mitochondrial function, which improved mitochondrial phenotypes in Huntington's disease models. CHIR99021 was shown to stabilize calpastatin, which suppressed calpain activa

Have you noticed the recent massive progress in artificial food (vegetarian alternatives of meat, cheese etc)?
I've recently tried a few of those vegetarian alternatives, and all of them were almost as good as the real thing. The same taste, texture etc. The artificial cheese made of almonds was especially amazing. Somehow, the researchers have managed to create an artificial cheese which has a better (!) taste than any traditional cheese I've ever tasted. The biggest problem with those alternatives is th

What's in a Name? Experts Say Texas 'Heartbeat Law' Misleads
Texas' latest bill restricting abortion, referred to as a "heartbeat bill," references the point in time when the embryo's cardiac activity can first be detected by an ultrasound. The moniker has helped rally supporters around the law nationwide, but health care experts say the term is not medically accurate.

Social cost of 2019's plastic more than GDP of India
The pollution, emissions and clean-up costs of plastic produced in 2019 alone could be $3.7 trillion, according to a report released Monday by wildlife charity WWF, warning of the environmental and economic burden of this "seemingly cheap" material.
