Mathematicians welcome computer-assisted proof in grand unification theory

Posted by in categories: computing, mathematics

Once researchers have done the hard work of translating a set of mathematical concepts into a proof assistant, the program generates a library of computer code that can be built on by other researchers and used to define higher-level mathematical objects. In this way, proof assistants can help to verify mathematical proofs that would otherwise be time-consuming and difficult, perhaps even practically impossible, for a human to check.

Proof assistants have long had their fans, but this is the first time that they have played a major role at the cutting edge of a field, says Kevin Buzzard, a mathematician at Imperial College London who was part of a collaboration that checked Scholze and Clausen’s result. “The big remaining question was: can they handle complex mathematics?” Says Buzzard. “We showed that they can.”

And it all happened much faster than anyone had imagined. Scholze laid out his challenge to proof-assistant experts in December 2020, and it was taken up by a group of volunteers led by Johan Commelin, a mathematician at the University of Freiburg in Germany. On 5 June — less than six months later — Scholze posted on Buzzard’s blog that the main part of the experiment had succeeded. “I find it absolutely insane that interactive proof assistants are now at the level that, within a very reasonable time span, they can formally verify difficult original research,” Scholze wrote.

Young Chaotic Star System Reveals Secrets of Planet Formation

Posted by in category: cosmology

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.

Quantum Breakthrough: New Invention Keeps Qubits of Light Stable at Room Temperature

Posted by in categories: encryption, energy, quantum physics

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.

We Dont Have Much Longer to Become a Type 1 Civilization

Posted by in categories: cosmology, space travel

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.

Scientists Prepare for Next Coronavirus Pandemic, Maybe in 2028?

Posted by in categories: biotech/medical, futurism

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.

Cells optimized to improve healthy ageing compound

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

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.

Anti-aging protein in red blood cells helps stave off cognitive decline

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

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.
