The Andromeda Study: A Femto-Spacecraft Mission to Alpha Centauri — Draft report finally published!!!

Posted by in categories: energy, engineering, physics, space

“This paper discusses the physics, engineering and mission architecture relating to a gram-sized interstellar probe propelled by a laser beam. The objectives are to design a fly-by mission to Alpha Centauri with a total mission duration of 50 years travelling at a cruise speed of 0.1c. Furthermore, optical data from the target star system is to be obtained and sent back to the Solar system. The main challenges of such a mission are presented and possible solutions proposed. The results show that by extrapolating from currently existing technology, such a mission would be feasible. The total mass of the proposed spacecraft is 23g and the space-based laser infrastructure has a beam power output of 15GW. Rurther exploration of the laser — spacecraft tradespace and associated technologies are necessary.”

AI Will Make Fake News Video — and Fight It As Well

Posted by in categories: engineering, finance, information science, robotics/AI

Just weeks after one research team appeared to put words in a leader’s mouth, here comes a new tool that can check questionable video for a pulse.

A recent demonstration showing how easy it is to spoof video of a world leader recently made headlines, foretelling a future where robot-created videos cause political and financial havoc. But now comes word of an antidote. On Monday, a group of computer scientists from Carnegie Mellon University’s Software Engineering Institute published new research showing how algorithms can tell whether the person on-screen has a human heartbeat. The technique will help future intelligence analysts, journalists, or just scared television viewers detect the difference between spoofed video and the real thing.

A living programmable biocomputing device based on RNA

Posted by in categories: biotech/medical, computing, engineering, nanotechnology, sustainability

“Ribocomputing devices” ( yellow) developed by a team at the Wyss Institute can now be used by synthetic biologists to sense and interpret multiple signals in cells and logically instruct their ribosomes (blue and green) to produce different proteins. (credit: Wyss Institute at Harvard University)

Synthetic biologists at Harvard’s Wyss Institute for Biologically Inspired Engineering and associates have developed a living programmable “ribocomputing” device based on networks of precisely designed, self-assembling synthetic RNAs (ribonucleic acid). The RNAs can sense multiple biosignals and make logical decisions to control protein production with high precision.

4D Camera to Improve Machine Vision for Robots and Virtual Reality

Posted by in categories: engineering, robotics/AI, virtual reality

A new type of camera built by Stanford engineers and funded by the NSF and Intel generates a four dimensional image that is capable of capturing nearly 140 degrees of information.

The 4D camera, built by Donald Dansereau, a postdoctoral fellow in electrical engineering and Gordon Wetzstein, assistant professor of electrical engineering at Stanford, along with colleagues from the University of California, San Diego is the first single-lens, wide field of view, light field camera ever made.

Floating City Project Wants To Make An ‘Unregulated’ Hub Of Scientific Research

Posted by in categories: biotech/medical, economics, engineering, food, governance, law, nanotechnology, robotics/AI, sustainability

In the hopes of rising above the laws and regulations of terrestrial nations, a group of Silicon Valley millionaires has bold plans to build a floating city in Tahiti, French Polynesia. It sounds like the start of a sci-fi dystopia (in fact, this is the basic premise behind the video game Bioshock), but the brains behind the project say their techno-libertarian community could become a paradise for technological entrepreneurship and scientific innovation.

The Seasteading Institute was set up in 2008 by billionaire PayPal founder Peter Thiel and software engineer, poker player, and political economic theorist Patri Friedman. Both ardent libertarians, their wide-eyed mission is to “establish permanent, autonomous ocean communities to enable experimentation and innovation with diverse social, political, and legal systems.”

“Seasteading will create unique opportunities for aquaculture, vertical farming, and scientific and engineering research into ecology, wave energy, medicine, nanotechnology, computer science, marine structures, biofuels, etc,” their website reads.

How Aliens Might Use ‘Network Theory’ For Galactic Communications

Posted by in categories: alien life, engineering

Advanced technological civilizations looking for efficient communication from one end of a galaxy to another would best be served by tapping into a network of transiting extrasolar earths. That is, extrasolar earths capable of being observed transiting across the face of their parent stars. Or so says an exoplanet researcher in the U.K.

Kepler-type space observatories out looking for transits of extrasolar earths, could also look for the telltale signatures of optical lasers or even alien macro-engineering projects that might be manipulated to signal another civilization.

Re-engineered macrophages to treat cancer.


Today we have a new study where researchers have created immune cells that ignore the way cancer tries to hide from detection.

Hiding in plain sight
