Technology to Make Interstellar Missions Possible and Affordable

Posted by in categories: physics, space travel

Arrays of lasers can be used to push light weight solar sails to other stars. This has been funded with over $100 millon and it builds upon the technology of the $600 billion laser and photonics industry. A recent paper looks at how different technological improvements will make it more feasible and improve the costs. Integrated photonics and mass production of most of the modular systems will be fundamentally necessary to afford the full-scale realization of this vision. Researchers have derived an analytical cost model which is driven by the fundamental physics of the proposed system. This allows us to make economically informed decisions and create a logical path forward to interstellar flight.

The Power of Brain-Computer Interfaces | TVS

Posted by in categories: biotech/medical, computing, cyborgs, neuroscience, virtual reality

A Brain-Computer Interface (BCI) is a promising technology that has received increased attention in recent years. BCIs create a direct link from your brain to a computer. This technology has applications to many industries and sectors of our life. BCIs redefine how we approach medical treatment and communication for individuals with various conditions or injuries. BCIs also have applications in entertainment, specifically video games and VR. From being able to control a prosthetic limb with your mind, to being able to play a video game with your mind—the potential of BCIs are endless.

American Airlines Announces Agreement to Purchase Boom Supersonic Overture Aircraft, Places Deposit on 20 Overtures

Posted by in category: transportation

The ‘Son of Concorde’ will bring back supersonic travel to the U.S…

American Airlines, the world’s largest airline, has committed to buying 20 supersonic aircraft from a Colorado-based aircraft manufacturer, whose design is still under testing, a press release from the airline said.

Traveling at speeds faster than that of the sound was a regular event before the turn of the millennium. However, when the aircraft manufacturer Concorde went under, airlines had no option but to stick with subsonic aircraft. This is the reason why flights across the world are long when with supersonic travel, they could take only a few hours.

‘Jurassic Park’? Scientists want to resurrect Australia’s Tasmanian tiger

Posted by in categories: biotech/medical, existential risks, genetics

Is de-extinction realistic?

Scientists in the US and Australia have announced a multi-million dollar project — resurrecting the extinct Tasmanian tiger. The last known marsupial officially called a thylacine, died in the 1930s. According to the team, the extinct thylacine can be recreated using stem cells and gene-editing technology, and the first one could be “reintroduced” to the wild within 10 years.

We would strongly advocate that first and foremost we need to protect our biodiversity from further extinctions, but unfortunately we are not seeing a slowing down in species loss.

Artemis I to Launch First-of-a-Kind Deep Space Biology Mission

Posted by in categories: biological, particle physics, space

Its Biosentinel mission will launch aboard Artemis I.

NASA’s sending living cells to deep space for the first time. The BioSentinel mission will be the first long-duration biology experiment in deep space, a NASA post.

BioSentinel will monitor the growth and activity of yeast cells as they get bombarded by high-energy radiation particles in deep space and beam the data back to NASA researchers on Earth to help safeguard astronaut heath.

Black Holes Are the Terrifying Behemoths of Space. Here’s How They Tick

Posted by in categories: cosmology, physics

A new approach to an age-old question.

Black holes are among some of the most mysterious objects in the Universe. They are the remnants of massive stars that have reached the end of their life cycles and collapsed into a region of spacetime that is incredibly dense. Their gravitational force is so strong that nothing can escape their surface.

Senolytics rejuvenate the regenerative capacity of the heart

Posted by in categories: biotech/medical, life extension

Speaking at the Longevity Leaders conference earlier this year, King’s College London Professor Georgina Ellison-Hughes shared a fascinating insight into her work to establish the adult heart as a self-renewing organ with regenerative capacity.

Longevity. Technology: The heart is generally considered a “post-mitotic” organ, or one without regenerative capacity. As we age and encounter chronic disease, senescent cells accumulate in the heart, just as they do in other tissues and organs. Ellison-Hughes’ work has shown that cellular senescence may impact the efficacy of regenerative therapies, and that senolytics have the potential to rejuvenate the heart’s capacity to regenerate. We caught up with the professor to learn more.

Cellular senescence is one of the nine hallmarks of aging. It occurs when our cells stop reproducing and enter a zombie state where they refuse to die – hanging around and causing problems throughout our bodies. Ellison-Hughes is professor of regenerative muscle physiology at King’s and in 2019 was co-author of a study in Aging Cell, which found that senescent cells impaired regeneration in the human heart.
