As we get closer to the official debut of Rivian’s more affordable R2, we are finally getting a better idea of what to expect. After teasing the model for the first time yesterday, Rivian’s R2 was reportedly spotted filming in downtown LA shortly after.

Rivian opened the R2 website yesterday, teasing the first look at the new EV in an intro video. The new EV will be revealed on March 7 at its new flagship Laguna showroom.

Although Rivian teased the new model leading up to its highly anticipated debut, we have yet to see what it looks like in full, until now. A patent filed by Rivian last month revealed a more compact electric SUV than the R1S with slightly smaller headlights.

The U.S. Naval Research Laboratory (NRL), in collaboration with Kansas State University, has discovered slab waveguides based on the two-dimensional material hexagonal boron nitride. This milestone has been reported in the journal Advanced Materials.

Two-dimensional (2D) materials are a class of materials that can be reduced to the monolayer limit by mechanically peeling the layers apart. The weak interlayer attractions (van der Waals attraction) allow the layers to be separated via the so-called “Scotch tape” method.

The most well-known 2D material, graphene, is a semimetallic material consisting of a single layer of carbon atoms. Recently, other 2D materials including semiconducting (TMDs) and insulating hexagonal boron nitride (hBN) have also garnered attention. When reduced near the monolayer limit, 2D materials have unique nanoscale properties that are appealing for creating atomically thin electronic and .

University of Melbourne researchers are leading a new push to address the growing harm of antimicrobial resistance (AMR) as more humans and animals become seriously ill or die from infections that medicine once treated easily.

Over-use and misuse of microbe-killing drugs – including antibiotics, antivirals and antifungals – is the main driver accelerating the evolution of resistance to these drugs in bacteria, viruses, fungi and parasites around the world.

The World Health Organisation calls AMR a top global public health threat that was directly responsible for 1.27 million deaths and contributed to 4.95 million deaths in 2019.

Physicists have theorized the existence of new types of celestial objects that they name “nestars.”

These are gravitational condensate stars, or gravastars, nestled among other gravitational condensate stars, like a Russian matryoshka doll, or nesting doll.

This type of doll is distinguished by its hollow, round form and the ability to be split apart to reveal a sequence of increasingly smaller dolls nestled inside.

Some of the oddest cosmic phenomena are short but tremendously powerful bursts of radio waves, which, in a fraction of a second, can give off as much energy as the sun does in a year. Known as fast radio bursts, these incredibly bright flashes of energy are thought to be related to dying stars called magnetars. Now, using two separate telescopes, astronomers have observed one of these events just a few minutes before and after it occurred, giving the best look yet at what causes these strange events.

Astronomers used NASA’s NICER (Neutron Star Interior Composition Explorer) on the International Space Station and NuSTAR (Nuclear Spectroscopic Telescope Array) in low-Earth orbit to observe a magnetar called SGR 1935+2154. Magnetars are a type of neutron star, the dense core left behind after a star collapses and with an extremely strong magnetic field. In October 2022, this magnetar gave off one of these strange, fast radio bursts.

The H3’s main missions are to secure independent access to space and be competitive as international demand for satellite launches grows. “We made a big first step today toward achieving that goal,” Yamakawa said.

The launch is a boost for Japan’s space program following a recent streak of successes, including a historic precision touchdown on the moon of an unmanned spacecraft last month.

The liftoff was closely watched as a test for Japan’s space development after H3, in its debut flight last March, failed to ignite the second-stage engine. JAXA and its main contractor Mitsubishi Heavy Industries have been developing H3 as a successor to its current mainstay, H-2A, which is set to retire after two more flights.
