What are the breakthroughs we can expect on our countdown to the Singularity? Peter Diamandis shares twelve of the fifty he compiled.

It should be compulsory but secret, argues an American bioethicist.

In 1960, American physicist Freeman Dyson proposed the idea that an extremely advanced—and power-hungry—alien civilization could, in theory, harness the majority of their host star’s energy by building a vast structure around it to absorb its radiation.

Scientists in the field of SETI (Search for Extraterrestrial Intelligence) have carried out a number of searches for such structures, known as Dyson spheres—which could be constructed using material harvested from dismantled planets—without uncovering any compelling evidence for them.

Now, in a paper published in The Astrophysical Journal, researchers from Uppsala University, Sweden, and Heidelberg University, Germany, have proposed a new way to look for Dyson spheres that may have some advantages over previous attempts.

Since its acquisition of ITA Matrix Software eight years ago, Google has been quietly rolling out new tools for travelers. Its progress has been even more notable over the past months and weeks as it began unveiling tools to help predict flight delays, plan trips, and manage itineraries — among other things.

These changes have some wondering: Is Google making a run at total domination in the travel space? If it is, there’s a strong case to be made for its potential to disrupt the travel and hospitality sector with a similar approach to Amazon’s run at retail, and more recently grocery.

Β-hydroxybutyrate seems to prevent senescence of vascular tissue.

According to a study by Georgia State University scientists, a molecule called β-hydroxybutyrate has anti-aging effects on the vascular system; more specifically, the molecule appears to prevent senescence of vascular cells by promoting cellular quiescence instead [1].

Several automakers interested in electric vehicles are turning to solid-state batteries for next-gen electric cars in the “post Li-ion era.”

Now a startup developing all solid-state batteries (ASSB) secured backing from several high-profile investors, including several automakers, as it claims a breakthrough for the technology that will enable better electric cars.

Solid Power is a Colorado-based startup that spun out of a battery research program at the University of Colorado Boulder.

$82 Trillion to convert a desert to land that could grow crops to help feed the world…is it worth it?

Researchers simulated the effects of around 79 terawatts of solar panels and 3 terawatts of wind turbines. Computer modeling looked at the effect of covering 20 percent of the largest desert on the planet in solar panels and installing three million wind turbines.

There would be 16X the rain in the aridest parts of the Sahara, and double that of the Sahel.
