Can a Seattle Start-Up Launch a Fusion Reactor Into Space?

Posted by in categories: military, nuclear energy, satellites, sustainability

Practical nuclear fusion is, famously, always 10 years in the future. Except that the Pentagon recently gave an award to a tiny startup to launch a fusion power system into space in just five.

There is no shortage of organizations, from VC-backedstartups to nation states, trying to realize the dream of cheap, clean, and reliable power from nuclear fusion. But Avalanche Energy Designs, based near a Boeing facility in Seattle, is even more ambitious. It is working on modular “micro fusion packs,” small enough to hold in your hand yet capable of powering everything from electric cars to spaceships.

Last month, the Pentagon’s Defense Innovation Unit (DIU) announced it had awarded Avalanche an unspecified sum to develop its Orbitron fusion device to generate either heat or electricity, with the aim of powering a high-efficiency propulsion system aboard a prototype satellite in 2027. The contract to Avalanche was one of two awarded by the DIU—the second going to Seattle-based Ultra Safe Nuclear for development of its radioisotope battery.

Are Most Sites Vulnerable Due to Lack Of Encryption?

Bypassing complex encryption has become a main goal and pursuit to State-actors and cybercriminals alike. It has never been more important to focus on updated, resilient HTTPS configurations, according to the TLS Telemetry Report by F5 Labs, which uncovers the extent of internet encryption and the potential use or abuse of web encryption for malicious purposes.

Based on the screening of the top million websites in the world, the report claims that more than half of the web servers still allow unsecured RSA Exchange. In addition, the negation of authorization remains problematic, due to the prevalence of legacy servers updated only rarely.

Astronomers Discover Clouds of Sand In The Atmosphere of A Failed Star

Posted by in category: space

New observations from the James Webb Space Telescope have given us direct confirmation that some alien worlds have clouds of rock.

The telescope has directly detected silicate clouds in the atmosphere of a brown dwarf – the first time, according to an international team of astronomers, that such a detection has been made in a planetary-mass companion outside the Solar System.

The complete findings, the team says, constitute the best spectrum yet for a planetary mass-object. These results could not only help us better understand these so-called ‘failed stars’, but represent just a foretaste of what the JWST can do.

New technique significantly increases lifetimes of fuel cells and other devices

Posted by in categories: energy, materials

The adoption rate of fuel cells has increased owing to the rising need for clean energy.

In a research that could jump-start the work on a range of technologies, including fuel cells, which are key to storing solar and wind energy, MIT researchers have found a simple way to significantly increase the lifetimes of fuel cells and other devices – changing the pH of the system.

Fuel/electrolysis cells made of materials known as solid metal oxides are in interest for several reasons. In electrolysis mode, they are very efficient at converting electricity from a renewable source into a storable fuel like hydrogen or methane. This storable fuel can be used in the fuel cell mode to generate electricity when the sun is not shining, or the wind isn’t blowing.

Elon Musk’s crypto interview was broadcast on the South Korean government’s YouTube channel that was hacked and renamed ‘SpaceX Invest’

Posted by in categories: cybercrime/malcode, Elon Musk, government, space travel

The channel has around 262,000 subscribers and actively posts videos on government policies and current events. It’s the third YouTube account run by South Korea’s government to have been breached in the last two weeks, Korean daily JoongAng Ilbo’s Lee Jian reported.

The identities and motives of those behind the attacks are not immediately known, the paper wrote, citing a statement from the Ministry of Culture, Sports and Tourism.

The Korea Tourism Organization’s YouTube channel was breached twice once on Thursday and once on Friday and was suspended until Sunday, JoongAng Ilbo reported.

FOREVER YOUNG — The Peter Pan Case | Dr Vittorio Sabastiano Interview Clips

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

Dr Vittorio Sabastiano explains the possibilities on resetting the age of any cell type in the near future in this clip.

Dr. Vittorio Sebastiano is an Assistant Professor in the Department of Obstetrics and Gynecology at Stanford School of Medicine. His lab has established a new technology named ERA (Epigenetic Reprogramming of Aging), which repurposes the conceptual idea of reprogramming, with the goal to promote epigenetic rejuvenation of adult cells leaving their identity untouched. This new technology was patented and is being implemented by Turn Biotechnologies, of which Dr. Sebastiano is co-founder and Chair of the Scientific Advisory Board.

The Deutsche Physikalische Gesellschaft (DPG) with a tradition extending back to 1,845 is the largest physical society in the world with more than 61,000 members. The DPG sees itself as the forum and mouthpiece for physics and is a non-profit organisation that does not pursue financial interests. It supports the sharing of ideas and thoughts within the scientific community, fosters physics teaching and would also like to open a window to physics for all those with a healthy curiosity.
