Bilayer graphene inspires two-universe cosmological model
Physicists sometimes come up with crazy stories that sound like science fiction. Some turn out to be true, like how the curvature of space and time described by Einstein was eventually borne out by astronomical measurements. Others linger on as mere possibilities or mathematical curiosities.

Experts predict the results will foreshadow a widening in measures of the nation's racial and economic achievement gap.

Biomolecular insights into protein-insolubility-related disease
Amyloidosis is the collective name for a group of diseases characterized by the deposition of amyloids—insoluble proteins that form due to the misfolding and aggregation of soluble proteins—outside of cells. Such depositions lead to cellular dysfunctions, and take place in patients with Alzheimer's disease, Parkinson's disease and dementia. In the disease called hereditary (variant) transthyretin

Business intelligence acts as a precursor to strategy
Business Intelligence (BI) and analytics play a key role in strategy work. However, business intelligence is not just a data mass that supplements strategy or a self-evident prop, but, together with the predictions generated by new algorithms and computational models, it can even act as a driving force or "prime mover" in strategy formation, according to Yassine Talaoui's doctoral thesis at the Un

Characterization of cellulose synthase supercomplex in cotton fiber
About 180 billion tons of celluloses are produced by the world's vegetation annually, making this polysaccharide the most abundant biological macromolecule on earth. It is produced predominantly by vascular plants, by a large number of algae and also by some bacteria, protists and tunicates. Cellulose microfibrils used for cell wall deposition are usually synthesized at the plasma membrane by the

Researchers found the black widow binary using data from th

Marine life will face mass extinction if oceans continue to warm
As greenhouse gas emissions continue to warm the oceans, marine life biodiversity could plummet within the next few centuries to levels not seen since the extinction of the dinosaurs, according to new research. Oceanographers modeled future marine biodiversity under different projected climate scenarios and found that if emissions are not curbed, species losses from warming and oxygen depletion a

'Stressed' cells offer clues to eliminating build-up of toxic proteins in dementia
It's often said that a little stress can be good for you. Now scientists have shown that the same may be true for cells, uncovering a newly-discovered mechanism that might help prevent the build-up of tangles of proteins commonly seen in dementia. Scientists have identified a new mechanism that appears to reverse the build-up of aggregates, not by eliminating them completely, but rather by 'refold

Animals can survive the cold in multiple ways
Many animals combine multiple strategies to beat the cold, research finds.

Biologists often study these cold-survival strategies in isolation and treat them as mutually exclusive alternat

WAKE-mediated modulation of cVA perception via a hierarchical neuro-endocrine axis in Drosophila male-male courtship behaviour
Nature Communications, Published online: 06 May 2022; doi:10.1038/s41467-022-30165-2 The authors show that the Drosophila master regulator WAKE modulates the secretion of insulin-like peptides, triggering a decrease in 20-hydroxyecdysone levels. This lowers the perception of a male-specific sex pheromone and explains why WAKE-deficient Drosophila flies show male-male courtship behaviour.
