Stem cell technique winds back aging in human cells

Posted by in categories: biotech/medical, life extension

O,.,o.


Stanford scientists may have found a way to essentially return older cells to a more youthful state. The adult cells are treated with a mix of proteins from early embryonic development, which removes many of the molecular signs of aging. The cells closely resembled younger ones, and in mouse tests, older animals regained the muscle strength of youth.

Stem cells have the remarkable ability to differentiate into basically any other type of cell in the body. That’s not only important for healthy development of embryos, but it opens an intriguing possible treatment for replenishing lost cells to repair damage to organs and tissues.

Computational human cell reveals new insight on genetic information processing

Posted by in categories: biotech/medical, genetics

Researchers have developed the first computational model of a human cell and simulated its behavior for 15 minutes—the longest time achieved for a biological system of this complexity. In a new study, simulations reveal the effects of spatial organization within cells on some of the genetic processes that control the regulation and development of human traits and some human diseases.

The study, which produced a new computational platform that is available to any researcher, is published in the journal PLOS Computational Biology.

“This is the first program that allows researchers to set up a virtual human cell and change and geometries to observe cellular processes in real time,” said Zhaleh Ghaemi, a research scientist at the University of Illinois at Urbana-Champaign and lead author of the study.

Chinese father builds ‘baby pod’ to protect infant from coronavirus

Posted by in category: biotech/medical

SHANGHAI (Reuters) — The father of a two-month-old infant in Shanghai has created a custom-built pod complete with an air purification system to keep his baby safe from the coronavirus outbreak.

Cao Junjie, 30, refashioned a cat carrier to make the sealable pod that includes an air-quality monitor displaying the concentration of carbon dioxide inside.

“Because of the epidemic, I spent a month making this baby safety pod for my kid … It can provide a safe and comfortable environment for the baby,” Cao told Reuters on Wednesday.

Worker at NYC hospital where nurses wear trash bags as protection dies from coronavirus

Posted by in categories: biotech/medical, military, nanotechnology

I believe people are dying because the response to this is surreal. You can spend over $1.5 Trillion on an F-35 that has been grounded more times than grass, yet this is happening 😳. Cheap test kits were offered by startups, nanotech protective gear was offered by an Israeli startup. Yet for some reason bailing out Mar a Lago makes more sense.

The shortage of safety gear at one Manhattan hospital is so dire that desperate nurses have resorted to wearing trash bags — and some blame the situation for the coronavirus death of a beloved colleague.

Scientists have built a foam armor that stops bullets as well as heavy steel

A newly developed metallic foam can stop even the biggest of bullets, but as with steel, there’s still a margin for death.

Pentagon to Provide 5 Million Masks for Virus Effort, Esper Says

Posted by in categories: biotech/medical, military

The Defense Department will provide 5 million medical-grade air-filtering masks — 1 million of them available immediately — as well as 2,000 ventilators as it steps up its role in the U.S. response to the coronavirus pandemic, Secretary of Defense Mark Esper said.

The Pentagon can also make the Navy’s two hospital ships available on the East and West coasts, Esper told reporters Tuesday. But he emphasized that the ships and other military resources would best be able to treat some trauma cases to make room for coronavirus patients at civilian hospitals that are properly equipped to handle infections.

“They don’t have necessarily the space, the segregated spaces, you need to deal with infectious diseases,” Esper said at the Pentagon. “So one of the ways by which you could use either field hospitals, the hospital ships or things in between, is to take the pressure off of civilian hospitals when it comes to trauma cases, is to open up civilian hospital rooms for infectious diseases.”

First high-sensitivity dark matter axion hunting results from South Korea

Posted by in categories: cosmology, particle physics

Researchers at the Center for Axion and Precision Physics Research (CAPP), within the Institute for Basic Science (IBS, South Korea), have reported the first results of their search of axions, elusive, ultra-lightweight particles that are considered dark matter candidates. IBS-CAPP is located at Korea Advanced Institute of Science and Technology (KAIST). Published in Physical Review Letters, the analysis combines data taken over three months with a new axion-hunting apparatus developed over the last two years.

Proving the existence of axions could solve two of the biggest mysteries in modern physics at once: why galaxies orbiting within galaxy clusters are moving far faster than expected, and why two fundamental forces of nature follow different symmetry rules. The first conundrum was raised back in the 1930s, and was confirmed in the 1970s when astronomers noticed that the observed mass of the Milky Way galaxy could not explain the strong gravitational pull experienced by the stars in the galaxies. The second enigma, known as the strong CP problem, was dubbed by Forbes magazine as “the most underrated puzzle in all of physics” in 2019.

Symmetry is an important element of particle physics and CP refers to the Charge+Parity symmetry, where the laws of physics are the same if particles are interchanged with their corresponding antiparticles © in their mirror images ℗. In the case of the strong force, which is responsible for keeping nuclei together, CP violation is allowed theoretically, but has never been detected, even in the most sensitive experiments. On the other hand, CP symmetry is violated both theoretically and experimentally in the weak force, which underlies some types of radioactive decays. In 1977, theoretical physicists Roberto Peccei and Helen Quinn proposed the Peccei-Quinn symmetry as a theoretical solution to this problem, and two Nobel laureates in Physics, Frank Wilczek and Steven Weinberg, showed that the Peccei-Quinn symmetry results in a new particle: the . The particle was named after an American detergent, because it should clean the strong interactions mess.

Polis issues statewide stay-at-home order

Posted by in category: futurism

CENTENNIAL, Colo. (KDVR) — Gov. Jared Polis issued a statewide stay-at-home order Wednesday afternoon. It goes into effect 6 a.m. Thursday and will last until April 11.

Many Coloradans, including the vast majority of people in metro Denver, live in counties where stay-at-home orders have already been announced.

Polis said he is issuing the order to save Coloradans’ lives.
