Blue Origin’s founder explains how New Shepard and New Glenn enable humanity’s future in the solar system.

Jeff Bezos is not a man of little dreams. The world’s richest person, with an estimated net worth of more than $130 billion, is spending some of his wealth on his space startup, Blue Origin. Much of the attention that the company has received has focused on the billions he’s invested into the company, its plans to fly tourists on its suborbital New Shepard vehicle and its entry into the orbital launch market with its New Glenn rocket.

“Monks don’t discuss the true meaning of the Heart Sutra to worshippers; they just read it like poetry,” Kohei Ogawa, a robotics professor at the University of Osaka who worked on the robot, told The Diplomat. “But this doesn’t work. The monks are like robots.”

The Mindar android also bends gender, according to The Diplomat, with its human-like face and chest designed to evoke both male and female characteristics.

Testing a rail gun in the middle of a field has never been so fun! This rail gun includes 9-volt batteries as a portable source of power to charge the capacitors. The capacitors provide instantaneous amperage to the rail gun. When triggered, the rail gun fires an aluminum projectile.

And, it’s a success! The first test, run at 350 volts, successfully fires the projectile. The team will have to make some modifications for the next phase. Any suggestions for making the capacitors or the cables more stable?

Finding the best light-harvesting chemicals for use in solar cells can feel like searching for a needle in a haystack. Over the years, researchers have developed and tested thousands of different dyes and pigments to see how they absorb sunlight and convert it to electricity. Sorting through all of them requires an innovative approach.

Now, thanks to a study that combines the power of supercomputing with data science and experimental methods, researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and the University of Cambridge in England have developed a novel “design to device” approach to identify promising materials for dye-sensitized solar cells (DSSCs). DSSCs can be manufactured with low-cost, scalable techniques, allowing them to reach competitive performance-to-price ratios.

The team, led by Argonne materials scientist Jacqueline Cole, who is also head of the Molecular Engineering group at the University of Cambridge’s Cavendish Laboratory, used the Theta supercomputer at the Argonne Leadership Computing Facility (ALCF) to pinpoint five high-performing, low-cost dye materials from a pool of nearly 10,000 candidates for fabrication and device testing. The ALCF is a DOE Office of Science User Facility.

Circa 2017

Getting something from nothing sounds like a good deal, so for years scientists have been trying to exploit the tiny amount of energy that arises when objects are brought very close together. It’s a source of energy so obscure it was once derided as a fanciful source of “perpetual motion.” Now, a research team including Princeton scientists has found a way to harness a mysterious force of repulsion, which is one aspect of that force.

This energy, predicted seven decades ago by the Dutch scientist Hendrik Casimir, arises from quantum effects and can be seen experimentally by placing two opposing plates very close to each other in a vacuum. At close range, the plates repel each other, which could be useful to certain technologies. Until recently, however, harnessing this “Casimir force” to do anything useful seemed impossible.

Scientists have attributed the flying behaviour of these wingless arthropods to ‘ballooning’, where spiders can be carried thousands of miles by releasing trails of silk that propel them up and out on the wind.

However, the fact that ballooning has been observed when there is no wind to speak of, when skies are overcast and even in rainy conditions, raises the question: how do spiders take off with low levels of aerodynamic drag?

Biologists from the University of Bristol believe they have found the answer.
