Settling the final frontier

Posted by in categories: economics, military, space

An extract from Space 2.0 by Rod Pyle.

At the other extreme is the massive Dyson Sphere, theorized by physicist Freeman Dyson – a metallic globe large enough to hold a star at its centre and contain a human population at a sufficient distance from the star to comfortably support their survival. This is a highly theoretical idea and is more of a thought experiment than a workable design, at least with any foreseeable technology.

Concerns have been raised about what kinds of governments might take hold in space settlements, and what possible risks they might face from ever more powerful economic and military establishments back on Earth.

It’s a Wind Up: Gorgeous Spring-Powered Toy Car Not for Kids

Posted by in categories: energy, food

Circa 2011

This gorgeous, stainless steel and bronze toy car is simply named Toy Car, which seems an appropriately stripped-down name for such a minimalist vehicle. Without a body, or even a cover over the engine, you can see exactly how the car works.

It’s essentially a fancy version of the pull-back-and-go cars found in cereal boxes and kids’ fast-food “meals” everywhere. Pull the car backwards while pushing down and the motion of the turning wheels is stored as energy in a coiled spring inside the big central toothed wheel. Let go and it unwinds, propelling the machine forward. When the spring has fully sprung, a clutch disengages and lets the car roll free.

NASA’s James Webb Space Telescope Successfully Completes a Critical Milestone

Posted by in category: space

Testing teams have successfully completed a critical milestone focused on demonstrating that NASAs James Webb Space Telescope will respond to commands once in space.

Known as a “Ground Segment Test,” this is the first time commands to power on and test Webb’s scientific instruments have been sent to the fully-assembled observatory from its Mission Operations Center at the Space Telescope Science Institute (STScI) in Baltimore, Maryland.

Since reliably communicating with Webb when in space is a mission-critical priority for NASA, tests like these are part of a comprehensive regimen designed to validate and ensure all components of the observatory will function in space with the complex communications networks involved in both sending commands, and downlinking scientific data. This test successfully demonstrated the complete end-to-end flow from planning the science Webb will perform to posting the scientific data to the community archive.

A Tesla Electric Jet? Elon Musk Says 400Wh/kg Battery Volume Production Possible in 3–4 Years

Posted by in categories: Elon Musk, space travel, sustainability

Tesla CEO Elon Musk has updated the timeline on which he sees batteries enabling electric aircraft coming to maket. He now sees it happening in “3 to 4 years.” Several years ago, Musk, the CEO of both Tesla and SpaceX, said that he had a design for electric vertical take-off and landing (VTOL) a…

Dementia Kills Nearly Three Times More People Than Previously Thought

Posted by in categories: biotech/medical, health, neuroscience

Summary: An estimated 13.6% of deaths in the U.S could be attributed to dementia. The number is 2.7 times higher than the official reported dementia-related deaths. The underestimation varies greatly by race, with 7.1 times more older Black adults, and 4.1 times more Hispanic adults, dying from dementia that public records indicate.

Dementia may be an underlying cause of nearly three times more deaths in the U.S. than official records show, according to a new Boston University School of Public Health (BUSPH) study.

Faulty Brain Circuits Arise From Abnormal Fusion

Posted by in categories: biotech/medical, neuroscience

Summary: Discovery reveals neurons can lose their individuality in some conditions. The findings contradict the conventional belief that neurons always stay separated and never fuse.

A discovery that could rewrite the textbooks on neurons could also help us understand the basis of some neurological diseases.

“Our Solar System May Be Unusual”: Rogue Planets Unveiled With NASA’s Roman Space Telescope

Posted by in category: space

New simulations show that NASA ’s Nancy Grace Roman Space Telescope will be able to reveal myriad rogue planets – freely floating bodies that drift through our galaxy untethered to a star. Studying these island worlds will help us understand more about how planetary systems form, evolve, and break apart.

Astronomers discovered planets beyond our solar system, known as exoplanets, in the 1990s. We quickly went from knowing of only our own planetary system to realizing that planets likely outnumber the hundreds of billions of stars in our galaxy. Now, a team of scientists is finding ways to improve our understanding of planet demographics by searching for rogue worlds.

This could be the Air Force’s future flying car of choice

Posted by in categories: futurism, transportation

The Air Force is on the hunt for a Jetsons–style flying car, and service officials just got an eyeful of one of their very first prototypes.

Secretary of the Air Force Barbara Barrett, Air Force Chief of Staff Gen. Charles Q. Brown, Jr., and Chief Master Sgt. of the Air Force JoAnne S. Bass were among the officials present for the first Agility Prime electric vertical takeoff and landing flight (eVTOL) flight demonstration at Camp Mabry on Aug. 20.
