China mulls $10 trillion Earth-moon economic zone

Posted by in categories: economics, transportation

China is mulling of establishing an Earth-moon space economic zone by 2050, with insiders expecting the zone to generate $10 trillion a year.

Bao Weimin, director of the Science and Technology Commission of the China Aerospace Science and Technology Corporation, revealed the ambitious plan at a seminar on space economy on Wednesday, media reported Friday.

In a report on developing earth and moon space, Bao shared his thoughts on the huge economic potential in this field and pledged that the country would study its reliability, cost and flight-style transportation system between the Earth and moon, The Science and Technology Daily reported Friday.

Seattle-based Spaceflight says it’s handling the pre-launch logistics for a Japanese satellite that’s designed to spray artificial shooting stars into the sky.

Tokyo-based ALE’s spacecraft is just one of seven satellites due to be sent into orbit from New Zealand as early as Nov. 25, aboard a Rocket Lab Electron launch vehicle.

At Gala Held

Posted by in categories: biotech/medical, innovation

The televised gala, broadcast on the National Geographic Channel as well as YouTube and China’s Tencent, whose founder Ma Huateng is also a sponsor, played heavily on a theme that’s become somewhat tarnished in Silicon Valley in recent years—that scientific and technological progress will solve humanity’s biggest problems. For the past two years, Facebook and Google have both been battered by lawmakers and the public for how they’ve failed to eliminate the spread of fake news, conspiracy theories (sometimes about science) and content that connects violent extremists. Both Zuckerberg and Pichai have also countered rising complaints from the tech giants’ workforces.


Some of the top scientists who accepted Breakthrough Prize awards used the nationally broadcast ceremony to decry the spread of misinformation, problems that continue to dog the tech giants whose leaders, including Facebook CEO Mark Zuckerberg and Google CEO Sundar Pichai, celebrated at the glitzy Silicon Valley gala Sunday evening.

“Science is a rock of truth in a sea of fake news,” said physicist Peter van Nieuwenhuizen, who with collaborators Sergio Ferrara and Daniel Freedman accepted an award Sunday evening for their work around the theory of supergravity.

Specific phase of sleep to best calm an anxious brain identified

Posted by in categories: biotech/medical, neuroscience

A fascinating new study from scientists at UC Berkeley has homed in on exactly which phase of sleep seems to best keep anxiety levels in check. The research both affirms a causal association between sleep and anxiety, and suggests sleep deprivation lowers activity in the prefrontal cortex, an area of the brain that helps regulate our emotions.

For well over a century scientists have observed a correlation between sleep disruption and mood disorders such as anxiety and depression. Only in the last few years have clear neural mechanisms been discovered helping us understand exactly what our brains are doing when we are asleep, and how physiologically disruptive sleep deprivation can be.

A new study from UC Berkeley has focused more specifically on how sleep can modulate a person’s anxiety levels. Using a number of experimental measures, including polysomnography and functional MRI, the research first found that just one night of sleep deprivation resulted in 50 percent of the study subjects reporting anxiety levels the next day equal to those detected in subjects with clinically diagnosed anxiety disorders.

Microbiome-altering Alzheimer’s drug unexpectedly approved in China

Posted by in categories: biotech/medical, neuroscience

In a surprise to many researchers around the world, Chinese authorities recently approved a novel drug claimed to improve cognitive function in patients with Alzheimer’s disease. The drug, derived from a marine algae, is the first new Alzheimer’s drug to reach the market anywhere in the world in almost 20 years, and is suggested to reduce neuroinflammation by modulating a person’s gut microbiome.

GV-971, or sodium oligomannate, is derived from a common form of seaweed called brown algae. For several years the compound has been under investigation in China as a treatment to slow, or even reverse, cognitive decline associated with mild to moderate cases of Alzheimer’s disease.

The latest announcement from China’s National Medical Products Administration (NMPA) has granted the drug “conditional approval”, meaning it is to be fast-tracked to market based on positive early Phase 3 trial results. The “conditional approval” requires ongoing studies to verify efficacy and safety, however, it can now move to open market sales in China within the next month or two.

WWII Submarine Found 77 Years After It Disappeared Off Malta Coast

Posted by in category: futurism

Marine archaeologists recently identified the wreck of HMS Urge, a Royal Navy submarine that went missing in the Mediterranean Sea during World War II.

The submarine vanished during a mission from Malta to Alexandria, Egypt, on April 27, 1942, according to the Royal Navy. Historians believe that the submarine was sunk by German and Italian Forces that were present in the Malta vicinity from June 1940 to November 1942, Fox News noted.

The wreck of #WW2 submarine HMS Urge has been found off Malta.

Astronomers think the universe is a sphere. Here’s why that claim is so controversial

Posted by in category: cosmology

According to the theory of General Relativity, mass curves spacetime. As a result, the overall mass of the universe determines its shape. Indeed, scientists have been known to calculate the “critical density” of the universe, which is proportional to the square of the Hubble constant, a variable used in estimating the size, age and expansion rate of the universe. If the actual density of the universe is less than the critical density, it is predicted that the universe will forever expand, as there isn’t enough matter to stop it. This creates a flat, and open, universe.

Yet if the density of the universe is more than the critical density, then that means it has enough mass to stop expanding, which is what the latest study using Planck data is suggesting.

A closed universe could end consequentially with a scenario known as the “Big Crunch” — the opposite of a Big Bang, in a sense, and a state in which the universe contracts until it is compressed again to a single energetic point.
