China completes world’s largest solar telescope array with a whopping 313 dishes

Posted by in category: space

China has completed the construction of what is now the world’s largest array of telescopes dedicated to studying the sun and how its behavior affects the Earth.

The Daocheng Solar Radio Telescope (DSRT), located on a plateau in Sichuan province in southwest China, consists of 313 dishes, each with a diameter of 19.7 feet (6 meters), forming a circle with a circumference of 1.95 miles (3.14 kilometers).

The Failures and Opportunities of Immortality

Posted by in categories: bioengineering, biotech/medical, business, life extension, singularity

Steven Parton [00:00:37] Hello everyone. My name is Steven Parton and you are listening to the feedback loop on Singularity Radio. This week our guest is business and technology reporter Peter Ward. Earlier this year, Peter released his book The Price of Immortality The Race to Live Forever, where he investigates the many movements and organizations that are seeking to increase the human lifespan from the Church of Perpetual Life in Florida to some of the biggest tech giants in Silicon Valley. In this episode, we explore Peter’s findings, which takes us on a tour from cryogenics to mind uploading from supplements to gene editing and much more. Along the way, we discuss the details of how one might actually achieve immortality, talking about senescent cells and telomeres. Discussing whether it’s better to live healthy than to live long. We also discuss the scams and failures that seem to dominate the longevity space, as well as the efforts that seem the most promising. And now, since we’re on the topic of discussing how precious life is, are waste no more of your precious time? So everyone, please welcome to the feedback loop. Peter Ward. Well then, Peter, thanks for joining me. I think the best place to start is in April of this year. You released a book called The Price of Immortality The Race to Live Forever and where I love to start with anyone who’s written a book is just hearing about your motivations for the book. Why did you decide that this was a topic worth exploring?

The Formula of Immortality

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

Dreaming about Immortality has a long history, almost as long as the failed quests to achieve it. And during all these years and years, the solutions for achieving immortality can fall in several categories. The first is to take some kind of “magic pill” – be it the fountain of youth, the elixir of life, the holy grail, till modern medicine of genetic engineering. After the magic “pills” proved to be a failure, the second attempt was through more creative endeavours, such as building a monastery, a temple, making a sculpture or painting, till nowadays when we talk about digital immortality and I guess soon about virtual immortality. And, of course, there were always the “party-spoilers”, the ones asking: why to be Immortal?

Humanity has changed in many ways, but the hope of the dream of Immortality remained and generation after generation, trying to find it in different ways or forms. So, keep with us as we travel alongside the deepest human dream, to see all (the failed) trials.

Scientists create ‘baby’ wormhole as sci-fi moves closer to fact

In science fiction – think films and TV like “Interstellar” and “Star Trek” – wormholes in the cosmos serve as portals through space and time for spacecraft to traverse unimaginable distances with ease. If only it were that simple.

Scientists have long pursued a deeper understanding of wormholes and now appear to be making progress. Researchers announced on Wednesday that they forged two minuscule simulated black holes – those extraordinarily dense celestial objects with gravity so powerful that not even light can escape – in a quantum computer and transmitted a message between them through what amounted to a tunnel in space-time.

New Undetectable Mechanism Of Antibiotic-Resistant Bacteria Discovered

Posted by in category: biotech/medical

A new mechanism that enables bacteria to form resistance to antibiotics has been discovered in a recent study conducted by researchers in Perth, Australia. In a process currently undetectable using traditional laboratory testing methods, the team observed the bacteria group A Streptococcus – the cause of strep throat – absorbing nutrients from the host organism that, in turn, enable them to bypass antibiotic treatment.

For bacteria to grow and multiply, they produce folates. Bacteriostatic antibiotics work to stop the bacteria’s ability to produce these folates, thus disabling their ability to multiply. The group A Streptococcus bacteria observed in the study, however, were seen to be using folates from the host when their own folate production was inhibited, causing a resistance to treatment from bacteriostatic antibiotics and likely making any infection worse.

The human body cannot become resistant to antimicrobial treatments. Rather, antimicrobial resistance (AMR) refers to bacteria or fungi’s resistance to antibiotics or antifungals, respectively. AMR is thought to pose a serious and rapidly growing threat to society.

Smart stem cells made from fat have the power to heal

Posted by in category: biotech/medical

New smart stem cells show a promising power to heal.

Researchers have reprogrammed human fat cells into adaptive smart stem cells that can lie dormant in the body until they are needed to heal various tissues. They demonstrated the cells’ effectiveness at healing damaged tissue in a mouse study.

To create the smart stem cells, the team from UNSW Sydney exposed human fat cells to a compound mixture. After about three and a half weeks, the cells lost their original identity and began acting like stem cells, or iMS (induced multipotent stem cells).
