Seemingly Magical — How To Fire Projectiles Through Materials Without Breaking Anything

Posted by in categories: nanotechnology, particle physics

Researchers at Vienna University of Technology have discovered why sometimes spectacular micro-explosions occur and other times ultra-thin layers of material remain almost intact when charged particles are shot through them.

It may seem like magic that some materials can withstand being shot through with fast, electrically charged ions without exhibiting holes afterward. This phenomenon, which would be impossible at the macroscopic level, becomes possible at the level of individual particles. However, not all materials exhibit this behavior. In recent years, various research groups have conducted experiments with varying results.

Vienna University of Technology researchers have been able to provide a detailed explanation for why some materials are perforated while others are not. This is of particular interest in the processing of thin membranes, which are designed to have tailor-made nano-pores that can trap, hold, or allow specific atoms or molecules to pass through.

Sepsis is one of the most expensive medical conditions in the world: Research clarifies how it can lead to cell death

Posted by in category: biotech/medical

Sepsis is a life-threatening condition arising from the body’s overreactive response against an infection, leading it to injure its own tissues and organs. The first known reference to “sepsis” dates back more than 2,700 years, when the Greek poet Homer used it as a derivative of the word “sepo,” meaning “I rot.”

Despite dramatic improvements in understanding the immunological mechanisms behind , it still remains a major medical concern, affecting 750,000 people in the U.S. and nearly 50 million people globally each year. Sepsis accounted for 11 million deaths worldwide in 2017, and is the most expensive medical condition in the U.S., costing over tens of billions of dollars annually.

Comet to approach Earth for first time since Neanderthals lived

Posted by in category: space

A comet that only orbits the sun once every 50,000 years is expected to be visible from Earth with the naked eye. The last time the comet visited, the Sahara desert was wet and fertile, Neanderthals and woolly mammoths still walked the Earth, and humans were—as far as we know—yet to reach North America.

C/2022 E3 (ZTF) was first spotted by the Zwicky Transient Facility (ZTF) on March 2, 2022, and is set to reach its closest point to the sun, or perihelion, on January 12, 2023. ZTF is an astronomical survey conducted by the Palomar Observatory in California.

Comets are “cosmic snowballs” made up of frozen gases, dust and rock that orbit the sun. As they approach our star, these fragile constructs are blasted with increasing amounts of radiation, a process that can produce two vast tails of gas and dust.

I missed his interview six times over the past year. Dr. Ian Hale of London who has done research a epidemics of the past 2,500 years agreed to give his interview for the seventh time and this time it happened.
The summary which I outlined from our discussion is
1-Any epidemic has a minimum four years cycle and its true about CORONA too.
2–2023 will be a catastrophic year due to the spread of mutants first in Northern Hemisphere and then in the Southern.
3-The world needs to act together to save generations whether it’s creating hospitals, vaccines, masks, or creating awareness.
4-CORONA will stay for all time. For the first few years catastrophically and then in its mild form.
5-We need to get vaccinated, wear masks, avoid public gatherings and follow all precautions.
6-Situation will be worsening in 2023 across the world due to the spread of mutants.
7-Vaccines may not work on These mutants.

Experts Debate the Risks of Made-to-Order DNA

Posted by in categories: biotech/medical, chemistry

In November 2016, virologist David Evans traveled to Geneva for a meeting of a World Health Organization committee on smallpox research. The deadly virus had been declared eradicated 36 years earlier; the only known live samples of smallpox were in the custody of the United States and Russian governments.

Evans, though, had a striking announcement: Months before the meeting, he and a colleague had created a close relative of smallpox virus, effectively from scratch, at their laboratory in Canada. In a subsequent report, the WHO wrote that the team’s method “did not require exceptional biochemical knowledge or skills, significant funds, or significant time.”
