The Cognitive Debt hypothesis proposes that repetitive negative thinking (RNT), a modifiable process common to many psychological risk factors for Alzheimer’s disease (AD) may itself increase risk. We sought to empirically examine relationships between RNT and markers of AD, compared with anxiety and depression symptoms.
The president also ordered a boost in the education of specialists in genetics and genome sequencing and the domestic production of necessary laboratory equipment, as well as tax cuts for biomedical research. Russia will also open world-class genome research centers which will, among their immediate goals, work on the development of treatments and vaccines for Covid-19.
The future database will be one of the tools that Russia hopes to use to assume a leading position in the biomedical industry. The government sees it as crucial for keeping the country competitive on the world stage going forward.
The Kurchatov Institute, which is best known for nuclear research, has been tasked with laying the foundation for the database, choosing the storage format and making tools for search and analysis. The institute has experience in the secure handling of large amounts of sensitive data and operates a number of data centers across Russia which are used for scientific collaboration projects.
The research described in this article has been published on a preprint server but has not yet been peer-reviewed by scientific or medical experts.
In hopes of developing a possible treatment for Covid-19, a team of MIT chemists has designed a drug candidate that they believe may block coronaviruses’ ability to enter human cells. The potential drug is a short protein fragment, or peptide, that mimics a protein found on the surface of human cells.
The researchers have shown that their new peptide can bind to the viral protein that coronaviruses use to enter human cells, potentially disarming it.

“Properties that have never been found in nature”
New claims that the novel coronavirus SARS-CoV-2 was engineered have been dismissed by scientific and intelligence experts.
The authors of a British-Norwegian vaccine study—accepted by the Quarterly Review of Biophysics—claim that the coronavirus’s spike protein contains sequences that appear to be artificially inserted.

There is great promise in 2020 that we might be able to make our bodies young without having to explicitly repair molecular damage, but just by changing the signaling environment.
Do we need to add signals that say “young” or remove signals that say “old”?
Does infusion of biochemical signals from young blood plasma rejuvenate tissues of an old animal? Or are there dissolved signal proteins in old animals that must be removed?
SARS-CoV-2 can infect and replicate in cells that line the inside of the human intestines, suggests study using gut organoids.
Being an astronaut looks like an exciting and glamorous career. But have you ever thought about the dangers that these people face by being exposed to extreme conditions, such as radiation and microgravity?
Living and working in microgravity can impact your whole body in different ways. On the other hand, the human body is capable of adapting its physiology to survive in diverse conditions.

Mentions aging!
Obesity affects more than 40 percent of adults in the United States and 13 percent of the global population. With obesity comes a variety of other interconnected diseases including cardiovascular disease, diabetes, and fatty liver disease, which makes the disease one of the most difficult—and most crucial—to treat.
“Obesity is the biggest health problem in the United States. But, it is hard for people to lose weight and keep it off; being on a diet can be so difficult. So, a pharmacological approach, or a drug, could help out and would be beneficial for all of society,” said Webster Santos, professor of chemistry and the Cliff and Agnes Lilly Faculty Fellow of Drug Discovery in the College of Science at Virginia Tech.
Persistently engaging in negative thinking patterns may raise the risk of Alzheimer’s disease, finds a new UCL-led study.
In the study of people aged over 55, published in Alzheimer’s & Dementia, researchers found ‘repetitive negative thinking’ (RNT) is linked to subsequent cognitive decline as well as the deposition of harmful brain proteins linked to Alzheimer’s.
The researchers say RNT should now be further investigated as a potential risk factor for dementia, and psychological tools, such as mindfulness or meditation, should be studied to see if these could reduce dementia risk.
