The fossil was a male Paranthropus robustus, a species that existed alongside our early human ancestors as a ‘cousin species’.
Academics from La Trobe University’s Archaeology Department in Melbourne, Australia led the excavation and reconstruction of the large-toothed rare skull from the Drimolen Main Quarry north of Johannesburg, South Africa.
Researchers described the fossil — that was found in 2018 on South African Father’s Day (June 20) — as exciting.
The racecars themselves will be partially designed by six teams of high school kids from across the country, as New Atlas reports. The best two teams emerging from a series of challenges “will win a once-in-a-lifetime opportunity to build and race two vehicles on the Moon,” according to a February press release.
“Competitors will then race their rovers remotely, navigating through harsh terrain, racing around a sphere of cameras, which will capture every aspect,” the statement reads.
Moon Mark CTO Todd Wallach told New Atlas that teams will have “near real time visuals, telemetry and command and control” of the racecars.
Graphene, an atomically thin carbon layer through which electrons can travel virtually unimpeded, has been extensively studied since its first successful isolation more than 15 years ago. Among its many unique properties is the ability to support highly confined electromagnetic waves coupled to oscillations of electronic charge—plasmon polaritons—that have potentially broad applications in nanotechnology, including biosensing, quantum information, and solar energy.
However, in order to support plasmon polaritons, graphene must be charged by applying a voltage to a nearby metal gate, which greatly increases the size and complexity of nanoscale devices. Columbia University researchers report that they have achieved plasmonically active graphene with record-high charge density without an external gate. They accomplished this by exploiting novel interlayer charge transfer with a two-dimensional electron-acceptor known as α-RuCl3. The study is available now online as an open access article and will appear in the December 9th issue of Nano Letters.
“This work allows us to use graphene as a plasmonic material without metal gates or voltage sources, making it possible to create stand-alone graphene plasmonic structures for the first time” said co-PI James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering.
Wherever you have fluid, there you can also find vortex rings.
Now, scientists have found vortex rings somewhere fascinating — inside a tiny pillar made of a magnetic material, the gadolinium-cobalt intermetallic compound GdCo2.
If you’ve seen smoke rings, or bubble rings under water, you’ve seen vortex rings: doughnut-shaped vortices that form when fluid flows back on itself after being forced through a hole.

Berkeley — An ultrasensitive, superfluid gyroscope developed by physicists at UC Berkeley has the potential to surpass today’s most sensitive devices for measuring absolute rotation or spin.
In a paper in this week’s issue of Nature, physics professor Richard Packard and his colleagues, graduate students Keith Schwab and Niels Bruckner, report a proof-of-principle demonstration of the new device.
Their prototype superfluid gyroscope already is quite sensitive and they believe its sensitivity will eventually surpass that of the ring laser gyroscope, a highly sensitive device used in advanced commercial aircraft inertial guidance systems. Packard’s immediate goal is to create a version with a sensitivity 10,000 times greater than the team has achieved to date.

The Commission helps to shape the EU’s overall strategy, proposes new EU laws and policies, monitors their implementation and manages the EU budget. It also plays a significant role in supporting international development and delivering aid.
Following the result of the European elections, and the mandate received from the European Council and the European Parliament, the Dr Ursula von der Leyen Commission put forward a set of ambitious goals for Europe’s future: climate neutrality by 2050; making the 2020s Europe’s Digital Decade; and making Europe stronger in the world with a more geopolitical approach.
