A set of brain signals known to assist memories form may additionally influence blood glucose levels, finds brand-new research in rats. Researchers at NYU Grossman College of Medicine discovered that a strange signaling pattern in the brain area called the hippocampus, connected by previous studies to memory development, likewise affects the metabolic process, the procedure...
Cryo-EM imaging reveals high-resolution side and top views of the viral RNA replication “crown” complex structure. Credit: Paul Ahlquist, Morgridge Institute for Research For the very first time, researchers at the Morgridge Institute for Research have created near-atomic resolution images of a significant viral protein complicated responsible for replicating the RNA genome of a member...
The newly described oligodendrocyte progenitor cells (green) contact long-distance neuronal axons (magenta) on the wall of the brain ventricles. According to a study published June 20 in Science, scientists discovered two types of glial cells in the brains of adult mice - an astrocyte and an oligodendrocyte progenitor cell - after pushing neural stem cells to...

Credit: LAWRENCE BERKELEY NATIONAL LABORATORY An antibody treatment that seems to reduce the effects of all recognized SARS-CoV-2 pressures and various other coronaviruses was created with some help from architectural biologist Jay Nix. Lifesaving COVID-19 injections are enabling us to feel optimistic once again, after over a...
There are significant differences in species numbers among the major branches of the tree of life. Some groups of organisms have numerous species, while others have some. For example, animals, plants, and fungi each have more than 100,000 known species, how most of the others-- such as many algal and bacterial groups-- have 10,000...
MIT researchers have devised a way to program memories into bacterial cells by rewriting their DNA more efficiently. Credit: MIT News, iStockphoto Organic engineers at MIT have created a brand-new way to edit bacterial genomes successfully and program memories right into microbial cells by revising their DNA. Using this technique, various spatial and temporal information...

They discovered that the binding of proteins to one point of a DNA molecule could affect an additional binding point at a...
Scanning was completed both during Time 1 and Time 2 (approximately 1.5 years later) in each of the 5 age groups (6-year-olds, 10-year-olds, 14-year-olds, 16-year-olds, and 18+-year-olds).

Published...

Photo by Clay Banks on Unsplash There are many books on what's wrong with the economy ( Chang 2014; Keen 2011; Nelson 2018, Mazzucato 2018, Raworth 2018, Stanford 2015 ) and what we would need to do to change it. Considering the small change we've seen in economics training and effective policy economic thinking since the 2007/08 global...
