Researchers announced the achievement of an important milestone on the road to nuclear fusion and we’re at the threshold of fusion ignition.
Dozens of container ships are anchored off the ports of Los Angeles and Long Beach. A crush of advance orders from U.S. manufacturers and retailers is contributing to the bottlenecks.
Scientists at Australia’s RMIT investigating the massive untapped potential of wave energy have come up with a novel design for a convertor they say operates with far greater efficiency than comparable solutions, and which they hope could open the door to widespread commercial use of the technology. The team’s prototype employs a novel dual-turbine design that sidesteps some common technical issues, and proved capable of harvesting twice the energy from waves as current designs in early experiments.
The idea of capturing energy from ocean waves has been around for centuries, and recently we’re starting to see modern machines designed for these purposes take to the seas in some interesting forms. This includes rotating systems that extract power from vertical and horizontal movement, blowhole-like generators that capture energy as waves push water and air through concrete chambers, and squid-like generators with buoyant arms that rise and fall with the motion of the waves.
One of the more common approaches to harnessing wave energy is known as a point absorber buoy, which consists of a flotation device on the surface that is tethered to the seabed. As the buoy moves up and down with the passing waves, it drives an energy converter mechanism built onto the tether partway below the surface. This might be a geared drivetrain that uses the linear motion to spin a flywheel and generate power, as seen in some experimental designs.

Optical image stabilization combined with a lot more zoom.
Apple has been beaten to the periscope “folded” camera punch by pretty much every other smartphone manufacturer, but it continues to design and patent new takes on the now-commonplace tech. It was granted a patent for a new design that includes folded optics and “lens shifting” capabilities.
Folded optics, or more commonly known as periscope cameras, are a design that allows smartphones to gain considerably more optical zoom than a typical lens design by placing the lens array parallel to the long edge of a smartphone body and bending the transmission of light to the sensor by using one or more prisms. The design has been used by Samsung, Huawei, and others to make smartphone cameras that sport massive optical zooming capabilities compared to what Apple offers.
This latest patent was filed in January of2019but finally granted and published on August 17 of this year, as noted by Patently Apple.
The Shenzhou-12 crew, astronauts Nie Haisheng (commander), Liu Boming and Tang Hongbo, prepares for the second extravehicular activity (EVA or spacewalk) planned during their three months mission on the Tianhe core module (天和核心舱), the first and main component of the China Space Station (中国空间站), informally known as Tiangong (天宫, Heavenly Palace). During the last 30 days, the Shenzhou-12 (神舟十二号) astronauts “activated the magnetic levitation experiment facility” that “includes a chamber of high-level micro-gravity”, “completed assembly of a space centrifuge, an equipment used for centrifugalizing samples”, and performed some “spring cleaning” in the Tianhe core module.
