New observations of young stellar object Elias 2–27 confirm gravitational instabilities and planet-forming disk mass as key to formation of giant planets.

A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2–27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation. The results of the research are published today (June 17, 2021) in two papers in The Astrophysical Journal.

Protoplanetary disks — planet-forming disks made of gas and dust that surround newly formed young stars — are known to scientists as the birthplace of planets. The exact process of planet formation, however, has remained a mystery. The new research, led by Teresa Paneque-Carreño — a recent graduate of the Universidad de Chile and PhD student at the University of Leiden and the European Southern Observatory, and the primary author on the first of the two papers — focuses on unlocking the mystery of planet formation.

There are Sirt6 activators on the market, but since we are not seeing any major news about results I would question their value.

Sirtuins are highly conserved proteins that are involved in a variety of important cellular processes such as DNA repair, metabolism and circadian rhythms. The mammalian sirtuins (SIRT1-7) are a family of proteins that carry out NAD+-dependent protein deacylation and mono-ADP-ribosylation. These modifications on proteins can influence their stability, localisation within a cell and activity.

Researchers from University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at-270 degrees. Their discovery saves power and money and is a breakthrough in quantum research.

As almost all our private information is digitalized, it is increasingly important that we find ways to protect our data and ourselves from being hacked.

Quantum Cryptography is the researchers’ answer to this problem, and more specifically a certain kind of qubit — consisting of single photons: particles of light.

Goldman Sachs ramps up bitcoin trading in new partnership with Mike Novogratz’s Galaxy Digital.

The bank has begun trading bitcoin futures with Galaxy Digital, the crypto merchant bank founded by Mike Novogratz, CNBC has learned.

The trades represent the first time that Goldman has used a digital assets firm as a counterparty since the investment bank set up its cryptocurrency desk last month, according to Galaxy co-president Damien Vanderwilt.

The moves by Goldman, the preeminent global investment bank, may reverberate on Wall Street and beyond as banks increasingly face pressure from clients who want exposure to bitcoin. By being the first major U.S. bank to begin trading cryptocurrency, Goldman is essentially giving other banks cover to begin doing so as well, said Vanderwilt, a former Goldman partner who joined Galaxy last year.

For those not in the loop, the Kardashev Scale is a system of measurement invented by Soviet astronomer Nikolai Kardashev in 1964. It quantifies how advanced a civilization is according to how much energy they’re able to harness.

Type 1 civilizations have harnessed 100% of the accessible energy of their own planet. Type 2 has harnessed 100% of the accessible energy in their solar system. Type 3 has harnessed 100% of the accessible energy in their galaxy. There is no official Type 4 but it is conceivable that eventually a civilization could harness 100% of the accessible energy in the universe, and Type 5, which has harnessed all the accessible energy in the multiverse.

That’s some heavy stuff, well beyond the scope of this article. The public’s focus on near term manned spaceflight efforts these days belies a problem with our priorities. Grand, ambitious projects like settling the Moon and Mars grab our attention, while there’s still much left to be done on Earth.

CHICAGO, IL — Scientists are already preparing for a possible next coronavirus pandemic to strike, keeping with the seven-year pattern since 2004.

In future-looking research, Northwestern University Feinberg School of Medicine scientists have identified a novel target for a drug to treat SARS-CoV-2 that also could impact a new emerging coronavirus.

“God forbid we need this, but we will be ready,” said Karla Satchell, professor of microbiology-immunology at Feinberg, who leads an international team of scientists to analyze the important structures of the virus. The Northwestern team previously mapped the structure of a virus protein called nsp16, which is present in all coronaviruses. This new study provides critical information that could aid drug development against future coronaviruses as well as SARS-CoV-2.

The population on Earth is increasingly growing and people are expected to live longer in the future. Thus, better and more reliable therapies to treat human diseases such as Alzheimer’s and cardiovascular diseases are crucial. To cope with the challenge of ensuring healthy aging, a group of international scientists investigated the potential of biosynthesising several polyamines and polyamines analogs with already known functionalities in treating and preventing age-related diseases.

One of the most interesting molecules to study was spermidine, which is a natural product already present in people’s blood and an inducer of autophagy that is an essential cellular process for clearing damaged proteins, e.g., misfolded proteins in brain cells that can cause Alzheimer’s. When people get older the level of spermidine in the blood decrease and dietary supplements, or certain are needed to maintain a stable and high level of spermidine in the blood. However, those products are difficult to produce with traditional chemistry due to their structural complexity and extraction of natural resources is neither a commercially viable nor a sustainable approach.

Therefore, the researchers instead decided to open their biochemical toolbox and use classical metabolic engineering strategies to engineer the yeast metabolism to produce polyamines and polyamines analogs.

Research conducted by Qiang et al has discovered a link between a protein in red blood cells and age-related decline in cognitive performance. Published in the open access journal PLOS Biology on 17th June 2021, the study shows that depleting mouse blood of the protein ADORA2B leads to faster declines in memory, delays in auditory processing, and increased inflammation in the brain.

As around the world increase, so are the number of people who will experience . Because the amount of oxygen in the blood also declines with age, the team hypothesized that aging in the brain might be naturally held at bay by adenosine receptor A2B (ADORA2B), a protein on the membrane of which is known to help release oxygen from the blood cells so it can be used by the body. To test this idea, they created mice that lacked ADORA2B in their blood and compared behavioral and physiological measures with control mice.

The team found that as the mice got older, the hallmarks of cognitive decline—poor memory, hearing deficits, and in the brain—were all greater in the mice lacking ADORA2B than in the control mice. Additionally, after experiencing a period of oxygen deprivation, the behavioral and physiological effects on young mice without ADORA2B were much greater than those on normal young mice.

Perhaps better than medication.

Summary: Inexpensive, commercial video games may help those suffering from anxiety and depression to combat their symptoms. Researchers found that, in addition to conventional games, virtual reality games could help people overcome mental health problems.

Popular video games have the potential to provide low-cost, easy access, effective and stigma-free support for some mental health issues, researchers at Lero, the Science Foundation Ireland Research Centre for Software, have found.
