By Jim and Drury Ambitious plans to build a twenty kilometer (12.4 miles) tall space elevator tower have been announced by a Canadian space technology firm. Although this distance is a mere fraction of that reached in space missions, Thoth Technology says its ThothX Tower will make a major cost reduction in space flights by helping navigate the difficult first 50 kilometers (31 miles) of travel that traditionally requires rockets. In addition to needing to carry sufficient fuel to get a payload into orbit, they need extra fuel in order to carry the required fuel to reach that point in the first place. Despite first being proposed more than a century ago, the idea of a space elevator has always appeared fanciful. Thoth Technology has been granted a United States (US) patent for the elevator, which is pneumatically pressurized and actively-guided over its base.

When it comes to growing food, the sky’s the limit thanks to innovations like the Sky Urban Vertical Farming System. Designed and pioneered by the Singapore-based company Sky Greens, the vertical farming system is a revolutionary modern spin on the ancient practice of agriculture. Using cutting edge technology, the system demonstrates an energy efficient, environmentally friendly method of producing food that could be a powerful tool in feeding the ever-growing, increasingly urbanized, global population.

Hanson would be unimpressed by my use of the word “it” to describe his robots, though. His latest creations, Han and Sophia, are “he” and “she” respectively. And Hanson believes that the latter model will become the “first sentient robot, the first one to achieve human-like consciousness.”

This is because Sophia is smaller in size – all of her mechanisms fit inside a smaller chassis. This is beneficial for two reasons: she costs less to make in terms of materials and it takes her less energy to make facial expressions and move around.

“Because of this, she can make more of a difference in the world,” Hanson explains. He adds:

A study led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders — powerful accelerators that could be used to unravel the properties of nature’s fundamental building blocks.

The scientists had previously shown that boosting the energy of charged particles by having them “surf” a wave of ionized gas, or plasma, works well for electrons. While this method by itself could lead to smaller accelerators, electrons are only half the equation for future colliders. Now the researchers have hit another milestone by applying the technique to positrons at SLAC’s Facility for Advanced Accelerator Experimental Tests (FACET), a DOE Office of Science User Facility.

“Together with our previous achievement, the new study is a very important step toward making smaller, less expensive next-generation electron-positron colliders,” said SLAC’s Mark Hogan, co-author of the study published today in Nature. “FACET is the only place in the world where we can accelerate positrons and electrons with this method.”

(Phys.org)—Scientists have fabricated a flexible electrical circuit that, when cut into two pieces, can repair itself and fully restore its original conductivity. The circuit is made of a new gel that possesses a combination of properties that are not typically seen together: high conductivity, flexibility, and room-temperature self-healing. The gel could potentially offer self-healing for a variety of applications, including flexible electronics, soft robotics, artificial skins, biomimetic prostheses, and energy storage devices.

The researchers, led by Guihua Yu, an assistant professor at the University of Texas at Austin, have published a paper on the new self-healing gel in a recent issue of Nano Letters.

The new gel’s properties arise from its hybrid composition of two gels: a supramolecular gel, or ‘supergel’, is injected into a conductive polymer hydrogel matrix. As the researchers explain, this “guest-to-host” strategy allows the chemical and physical features of each component to be combined.

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or one picosecond.

Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.
