SARS-CoV-2 can Infect Dopamine Neurons causing Senescence

Posted by in categories: biotech/medical, chemistry, health, neuroscience

A new study reported that SARS-CoV-2, the virus that causes COVID, can infect dopamine neurons in the brain and trigger senescence—when a cell loses the ability to grow and divide. The researchers from Weill Cornell Medicine, Memorial Sloan Kettering Cancer Center, and Columbia University Vagelos College of Physicians and Surgeons suggest that further research on this finding may shed light on the neurological symptoms associated with long COVID, such as brain fog, lethargy, and depression.

The findings, published in Cell Stem Cell on Jan. 17, show that dopamine neurons infected with SARS-CoV-2 stop working and send out chemical signals that cause inflammation. Normally, these neurons produce dopamine, a neurotransmitter that plays a role in feelings of pleasure, motivation, memory, sleep, and movement. Damage to these neurons is also connected to Parkinson’s disease.

“This project started out to investigate how various types of cells in different organs respond to SARS-CoV-2 infection. We tested lung cells, heart cells, pancreatic beta cells, but the senescence pathway is only activated in dopamine neurons,” said senior author Dr. Shuibing Chen, director of the Center for Genomic Health, the Kilts Family Professor Surgery and a member of the Hartman Institute for Therapeutic Organ Regeneration at Weill Cornell Medicine. “This was a completely unexpected result.”

70 years of MKUltra, the CIA ‘mind-control’ program that inspired ‘Stranger Things’

Posted by in categories: biotech/medical, chemistry, government, life extension, neuroscience

MKUltra is not referenced explicitly on Stranger Things — the popular Netflix show — but the series seems to be inspired by the controversial CIA program. In the show, a government laboratory is conducting illegal experiments on a young girl and other persons, torturing them, and harnessing their special abilities for their own purposes. This is similar to the goals of the CIA human experimentation project, which was started 70 years ago.

Controversial and unethical experiments were conducted on human subjects by the Agency for the MKUltra project, including the use of mind control techniques and the administration of drugs such as LSD and other chemicals. Electroshock, hypnosis, sensory deprivation, verbal and sexual abuse, and other forms of torture were also part of the non-consensual experiments, which were created because the CIA was convinced that communists had discovered a way to control human minds. Its activities — which were hidden and classified before their files being destroyed after an investigation — remain a subject of concern and investigation to this day.

MKUltra was a CIA program involving the research and development of chemical and biological agents. According to official documents, it was “concerned with the research and development of chemical, biological and radiological materials capable of employment in clandestine operations to control human behavior.”

SES, Eutelsat, Hispasat: Why we’re investing in Europe’s Iris2 constellation; Starlink & Kuiper are problems for us

Posted by in categories: government, internet, satellites

BRUSSELS — Three of Europe’s biggest satellite fleet operators — SES, Eutelsat and Hispasat — explained why they are investing in the European Commission’s Iris2 multi-orbit satellite constellation, designed as a public-private partnership with the Commission and the 22-nation European Space Agency (ESA).

Three weeks before their SpaceRise consortium’s best-and-final bid is due, these companies said Iris2 gives them part ownership in a global medium-and low-Earth-orbit network whose capex is mainly government funded.

Hubble Spots Water Vapor in Small Exoplanet’s Atmosphere

Posted by in categories: alien life, chemistry

Steamy World Could Be a Sample of Water-Rich Planets Throughout Our Galaxy The search for life in space goes hand-in-hand with the search for water on planets around other stars. Water is one of the most common molecules in the universe, and all life on Earth requires it. Water functions as a solvent by dissolving substances and enabling key chemical reactions in animal, plant, and microbial cells. It is much better at this than other liquids.
