Could Elon Musk Lose the Satellite Market — and Win the Solar System?

Posted by in categories: Elon Musk, satellites, security

When SpaceX launched the world’s biggest rocket ship on Feb. 6, that kind of seemed like a big deal — but not everyone is impressed.

Previewing the SpaceX Falcon Heavy launch, The Wall Street Journal seemed perplexed. Yes, the Falcon Heavy is big, admitted the Journal. But as a “heavy-lift booster,” it said, it is a product designed to serve a market that’s suffering “significantly eroded commercial demand” and “uncertain commercial prospects.”

The problem, as the Journal (correctly) pointed out, is that thanks to advances in rocketry, electronics, and materials technology, “both national security and corporate satellites continue to get smaller and lighter” (and cheaper).

Europa may have hidden liquid ocean to sustain life, new study reveals

Posted by in categories: nuclear energy, space, sustainability

Jupiter is a giant hot gaseous planet situated after the asteroid belt at a distance of 365 million miles when it is the closest w.r.t Earth and 601 million miles when it is the farthest. It was just a few years back when Jupiter’s moon Europa was reported as a potential planet that can hose life. Europa headlined on the internet in 2016 after scientists were able to see water vapor like plumes erupting from its crust. But, as a part of new research at the University of Sao Paulo, Brazil, Europa might have liquid water flowing beneath its 10-kilometer deep ice crust. The researchers used data extracted the data from an analogous location on Earth and found that life is sustainable in even the harsh environment that Europa offers as it has a huge liquid ocean under its crust.

Douglas Galante is the part of the research team that stretched towards the Mponeng Gold Mine in Johannesburg, South Africa in such as evidence. During the research, they found that bacterium Candidatus Desulforudis Audaxviator survives inside the mine at the depth of 2.8 km without any sunlight. It uses the method of water radiolysis where the water molecules are dissociated with the help of ionizing radiation. The analysis of the mine highlighted the cracks that run throughout the mine filled with cracks that supply water containing radioactive uranium which in turns, helps the bacterium to break down water molecules and consume the free radicals produced.

Once the free radicals are generated, these subatomic molecules attack rocks in the surrounding which produces sulfate. This is what these bacteria utilize to synthesize energy and store it without even interacting with the sunlight. One of a kind findings confirmed that it was the very first time when scientists were able to explore a living organism using nuclear energy to survive directly. Galante stated that this ecosystem is analogous to that of Europa’s ocean which has a great amount of thermal energy and absolute zero temperature.

Harvard’s David Sinclair Treats Aging as a Disease and Plans to Launch a Clinical Trial to Prove It

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

Harvard University’s David Sinclair, world renowned for his anti-aging research, sees no limit on human life span and is collaborating on a clinical trial to evaluate the effectiveness of a new drug aimed at slowing the aging process…

“There is no maximum human life span,” says Sinclair, Ph.D., who is a professor in the Department of Genetics and co-director of the Paul F. Glenn Center for the Biology of Aging at Harvard Medical School. “Anyone who says that doesn’t know what they are talking about.”

Sinclair hopes to demonstrate what he has been researching, – and talking about, for the past 20 years – that aging is a disease, which can be treated.

ICOs & Altcoins rise and fall—yet, Bitcoin endures

Posted by in categories: bitcoin, cryptocurrencies, economics, government

At the end of 2017 and the first months of 2018, we witnessed a surge of interest in Initial Coin Offerings or ICOs. Perhaps the word “interest” gives too much credit to ICOs. Most are scams. ICOs are pushed through by vendor hype, rather than pulled through by investor research. They are almost all pump-and-dump schemes.

But what about Bitcoin? It is not a scam, but questions remain about regulation, intrinsic value* and its likelihood to be superseded by something better. Bitcoin skeptics point to two facts: (1) Bitcoin is open source, and so anyone can create an equally good altcoin. (2) Newer coins incorporate improvements that overcome governance and scaling issues: cost, transaction speed, the burgeoning electric needs of miners, or whatever…

While both statements are true, they miss the point. This is not a VHS-vs-Beta scenario. Bitcoin has achieved a 2-sided network and it is free to fold in every vetted improvement that comes along. For Bitcoin, all those other coins are simply beta tests.

Even the functional tokens will unwittingly feed their “improvements” into Bitcoin. For this reason, it is a safe bet that Bitcoin will reign supreme for years to come—perhaps even long enough for the dominos to fall.

Runoff pitting low-fat vs. low-carb to lose weight results in a tie

Posted by in categories: biotech/medical, life extension

Summary: A new study didn’t find much of a difference between healthy low-carb and low-fat diets. The people on both diets lost about the same amount of excess weight. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Is cutting carbs or cutting fat is better? A new study published in the Journal of the American Medical Association, suggest that it may not matter much.

A team of researchers led by Christopher Gardner, a professor of medicine at the Stanford University School of Medicine, followed 609 overweight adults ages 18 to 50. The researchers put the study participants, consisting of equal numbers of men and women, on either a low-carb diet or low-fat diet for 12 months.

Brain rejuvenating protein found in young blood

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

Summary: UCSF scientists discover a protein in young blood that rejuvenates an aging brain. [This article first appeared on LongevityFacts. Author: Brady Hartman. ]

Scientists have long been searching for the factors in young blood that give it its rejuvenating powers to drug form for widespread public use.

A team of researchers led by Saul Villeda, Ph.D., an assistant professor of anatomy at UC San Francisco discovered a brain-rejuvenating enzyme that improved memory in adult mice when restored to youthful levels. The researchers say the new protein could lead to new therapies for maintaining the healthy brain function of humans.

Parents are buying these gadgets to protect their kids from school shooters

Posted by in category: education

Parents have been stocking up on bulletproof backpacks, tracking devices and doorstops… to give children a fighting chance at surviving a gunman’s attack at school,” the N.Y. Post reports:

“BulletBlocker, a company that sells bulletproof backpacks ranging in price from $199 for a girly pink one to $490, has seen sales jump 300 percent since the Florida shooting.”

A $95 metal device called “JustinKase,” which is placed under a door and latches to the door’s jamb to prevent entry, was invented by a 17-year-old Wisconsin high school student, Justin Rivard.
