CEO Elon Musk teased it in April for the first time, and it was set to bring unprecedented momentum to the company’s years of development of Full Self-Driving and fully autonomous driving technologies.

However, Tesla is not quite ready to roll out the Robotaxi prototypes.

First reported by Bloomberg, Tesla is said to need more time to build the first units of the Robotaxi. Because it is built upon the automaker’s next-generation platform, which is to blame for the company’s lack of growth in 2024, more development is needed.

Wriggling critters armed with enzymes can break down plastics that would otherwise take decades, or even centuries to degrade.

At first glance there’s nothing particularly remarkable about waxworms. The larval form of wax moths, these pale wriggling grubs feed on the wax that bees use to make their honeycomb. For beekeepers, the pests are something to swiftly get rid of without a second thought.

But in 2017 molecular biologist Federica Bertocchini, who at the time was researching the embryonic development of vertebrates at the Spanish National Research Council, stumbled on a potentially game-changing discovery about these creatures.

You can now get a Starlink Mini in the US, wherever you are and even if you’re not paying for a residential subscription. SpaceX started offering select users the new Starlink dish model that’s small enough to fit in a backpack in late June. Despite its small size that makes it easy to transport and carry around, the Mini used to require an existing $150 standard service plan — you could only tack on the Mini Roam service for an additional fee of $30 a month. Now, you can get it on its own with a roaming service.

The mobile regional plan costs $150 a month and will give you access to unlimited data. It’s probably the better option if you live in an RV or travel to remote locations for extended periods of time. Meanwhile, the Mini Roam plan costs $50 a month and will give you access to 50GB of data, which is likely enough if you don’t live on the road full time. Take note that you can use Mini Roam in motion anytime, as long as you’re on land. The mobile regional plan has limited in-motion use and only works when you’re going slower than 10mph, though you can choose to add data meant for in-motion use on a per-GB basis.

Like Starlink’s other terminals, you’ll have to pay for the Mini up front. It will cost you $599 for the kit, which includes a kickstand, a pipe adapter, a power supply and a cord with a USB-C connector on one end and a barrel jack on the other. (As The Verge notes, you can plug it into a 100W USB-PD power bank if you don’t have access to other power sources.) There’s no Wi-Fi router with the kit, because it’s already integrated into the dish, giving you one less component to carry.

A super-sized Nano Transparent Screen (NTS) has been developed and commercialized for the first time in the world. This innovative screen can adjust its transparency according to the environment and can be produced at a low cost, paving the way for the widespread adoption of large transparent screens, which until now have been prohibitively expensive.

Spider spidroin revives the silken splendor.

In their quest to make silk powerful again, not by status but rather by thread strength, scientists turned to an arachnoid. Dragline silk, the thread by which the spider hangs itself from the web, is one of the strongest fibers; its tensile strength—a measure of how much a polymer deforms when strained—is almost thrice that of silkworm silk.2

Beyond durable fashion garments, tough silk fibers are coveted in parachutes, military protective gear, and automobile safety belts, among other applications, so scientists are keen to pull on these threads. While traditional silk production relies on sericulture, arachnophobes can relax: spider farms are not a thing.

RIKEN chemists have developed a molecule that enhances the performance of organic electronic devices and is also more stable than previous alternatives, raising the chances that it could be used in industrial manufacturing processes (Advanced Materials, “A novel n-type molecular dopant with a closed-shell electronic structure applicable to the vacuum-deposition process”).

Conventional electronic devices are made from hard semiconductors such as silicon, but increasingly organic semiconductor molecules are appearing in devices such as televisions and cell-phone displays that use organic light-emitting diodes (OLEDs).

Scientists have taken a significant step towards the development of tailor-made chiral nanocarriers with controllable release properties. These nanocarriers, inspired by nature’s helical molecules like DNA and proteins, hold immense potential for targeted drug delivery and other biomedical applications.

The study, led by Professors Emilio Quiñoá and Félix Freire at the Center for Research in Biological Chemistry and Molecular Materials (CiQUS), highlights the intricate relationship between the structure of helical polymers and their self-assembly into nanospheres. By carefully designing the secondary chain, the researchers were able to modulate the acidity of the polymers, influencing their aggregation patterns and leading to the formation of nanoespheres with varying densities.

Intriguingly, the size of these nanospheres could be precisely controlled by simply adjusting the water-to-solvent ratio during their preparation, eliminating the need for stabilizers. This eco-friendly approach paves the way for sustainable synthesis of these particles.

Ferromagnetism is an important physical phenomenon that plays a key role in many technologies. It is well-known that metals such as iron, cobalt and nickel are magnetic at room temperature because their electron spins are aligned in parallel — and it is only at very high temperatures that these materials lose their magnetic properties.

Researchers led by Professor Richard Warburton of the Department of Physics and the Swiss Nanoscience Institute of the University of Basel have shown that molybdenum disulfide also exhibits ferromagnetic properties under certain conditions. When subjected to low temperatures and an external magnetic field, the electron spins in this material all point in the same direction.

In their latest study, published in the journal Physical Review Letters (“Exchange energy of the ferromagnetic electronic ground state in a monolayer semiconductor”), the researchers determined how much energy it takes to flip an individual electron spin within this ferromagnetic state. This “exchange energy” is significant because it describes the stability of the ferromagnetism.
