Optics researchers from The University of Queensland and Nokia Bell Labs in the US have developed a new technique to demonstrate the time reversal of optical waves, which could transform the fields of advanced biomedical imaging and telecommunications.

Time reversal of waves in physics doesn’t mean traveling back to the future; it describes a special type of wave which can retrace a path backwards through an object, as if watching a movie of the traveling wave, played in reverse.

UQ’s Dr. Mickael Mounaix and Dr. Joel Carpenter, together with Dr. Nick Fontaine’s team at Nokia Bell Labs, are the first to demonstrate this time reversal of optical waves, using a new device they developed that allows full 3D control of light through an optical fiber.

Am I reading this wrong? Sunelight is literally a cure / weapon against corona? Or am I missing something / making an incorrect logical link?

Researchers from Tel Aviv University (TAU) have proven that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be available for private and commercial use.

This is the first study conducted on the disinfection efficiency of UV-LED irradiation at different wavelengths or frequencies on a virus from the family of coronaviruses. The study was led by Professor Hadas Mamane, Head of the Environmental Engineering Program at TAU’s School of Mechnical Engineering, Iby and Aladar Fleischman Faculty of Engineering. The article was published in November 2020 issue of the Journal of Photochemistry and Photobiology B: Biology.

“The entire world is currently looking for effective solutions to disinfect the coronavirus,” said Professor Mamane. “The problem is that in order to disinfect a bus, train, sports hall, or plane by chemical spraying, you need physical manpower, and in order for the spraying to be effective, you have to give the chemical time to act on the surface. Disinfection systems based on LED bulbs, however, can be installed in the ventilation system and air conditioner, for example, and sterilize the air sucked in and then emitted into the room.

A bit of everything here from hallmarks of aging to epigenetic reprogramming(which effects telomeres, gene expression, etc) and even diet.

In this talk given at Ending Age-Related Diseases 2020, Dr. Kris Verburgh of the Free University of Brussels discusses the methods by which people might lead longer, healthier lives. While some of these methods involve the use of advanced rejuvenation biotechnology techniques, others are simpler to implement and require a minimum amount of technology, such as nutrition and exercise, along with health-monitoring technology that already exists in the public space.

Researchers at the Francis Crick Institute and University College London have rebuilt a human thymus, an essential organ in the immune system, using human stem cells and a bioengineered scaffold. Their work is an important step towards being able to build artificial thymi which could be used as transplants.

The thymus is an organ in the chest where T lymphocytes, which play a vital role in the immune system, mature. If the thymus does not work properly or does not form during foetal development in the womb, this can lead to diseases such as severe immunodeficiency, where the body cannot fight infectious diseases or , or autoimmunity, where the immune system mistakenly attacks the patient’s own healthy tissue.

In their proof-of-concept study, published in Nature Communications today, the scientists rebuilt thymi using taken from patients who had to have the organ removed during surgery. When transplanted into mice, the bioengineered thymi were able to support the development of mature and functional human T lymphocytes.

Better doublecheck your kitchenware! 😃

The results indicate that environmental chemicals may be an important contributing factor to the obesity epidemic. Unfortunately, it is practically impossible to avoid exposure to PFASs as they have been widely used in products like cookware, clothes, shoes, wrappers and furniture, to make them more stain-resistant, waterproof and/or nonstick.

Additionally, even though some PFASs (but not all) are no longer manufactured in the U.S., they continue to be in other countries around the globe. The long life of the chemicals and their ability to travel long distances through the air makes exposure possible even years after manufacturing and at completely different geographical locations.

Nevertheless, Sun gives one more reason to stop eating junk food: “We know that PFAS exist in food packaging materials, like fast-food wrappers and microwave popcorn bags. If you don’t eat those foods, you can possibly reduce your exposure.”

As much of the aviation industry fights to survive the coronavirus pandemic, some economists and engineers see the crisis as an opportunity to use stimulus funds to propel air travel to a carbon-neutral future. Photo illustration: George Downs.

Microsoft co-founder Bill Gates believes a return to “normal” life is further down the road for the US than people expect, despite a Covid-19 vaccine being approved and distributed this week.

Conceding that by the summer of 2021, the US should be “way closer to normal than we are now,” Gates, who has donated millions to vaccination efforts through his foundation, believes a full return to normal will likely not be possible until after 2022.

The billionaire told CNN on Sunday that “unless we help other countries get rid of this disease” and see “high vaccination rates” within the US, the “risk of reintroduction” will be possible.
