As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that governs the mixing of liquids is not limited to mixing bowls; it also affects the behavior of things inside cells. It s been known for several years that some proteins behave like liquids, and that some liquid-like proteins don t mix together. However, very little is

While researchers continue to try to find the key that unlocks the cause of Parkinson s disease, new research suggests that what a person eats could make a difference.
Researchers in Canada found a strong correlation between eating either a Mediterranean diet or the MIND diet which combines elements of the Mediterranean diet and a diet known as Dietary Approaches to Stop Hypertension and a delay in onset of Parkinson s disease.
New Genetic Disorder Affects Brain and Craniofacial Skeleton by Angela Mohan on January 22, 2021 at 12:10 PM
New genetic disorder is characterized by developmental delays and malformations of the brain, heart and facial features. Named linkage-specific-deubiquitylation-deficiency-induced embryonic defects syndrome (LINKED), the disorder is caused by a mutated version of the OTUD5 gene, that affects the key molecular steps in embryo development.
The findings indicate that the newly identified pathway may be essential for human development and may also underlie other disorders that are present at birth. The information will help scientists better understand such diseases both common and rare and improve patient care. The results were reported in

After winning the US presidential election, Democrat Joe Biden moved quickly to begin naming the experts who will advise him on a range of issues including science.
He immediately announced a task force of public-health specialists who will counsel him on a strategy to curtail the coronavirus pandemic, and he created a new position on the White House National Security Council devoted to climate change. Scientists have welcomed Biden’s swift actions in picking advisers with strong backgrounds in research and evidence-based policy. His predecessor, former Republican president Donald Trump, appointed multiple climate-change sceptics to
