How seriously do you take your diet?

It is one of the foundations upon which everything else stands.

Domino’s and Nuro teamed up for autonomous pizza delivery in Houston. Don’t get your hopes up, though, for a driverless drop-off: Many restrictions apply, and only a handful of hungry people can opt in right now.

Beginning this week, select customers who place a prepaid website order from the lone participating pizza shop in Woodland Heights can opt to have their food delivered by Nuro’s R2 robot. Those lucky patrons receive text alerts highlighting R2’s location, and can track the vehicle via GPS on the order confirmation page. Domino’s also provides a unique personal identification number required to open the bot’s door and reveal that piping hot pizza.

“We’re excited to continue innovating the delivery experience for Domino’s customers by testing autonomous delivery with Nuro in Houston,” Dennis Maloney, Domino’s senior vice president and chief innovation officer, said in a statement. “There is still so much for our brand to learn about the autonomous delivery space.”

Topological insulators have notable manifestations of electronic properties. The helicity-dependent photocurrents in such devices are underpinned by spin momentum-locking of surface Dirac electrons that are weak and easily overshadowed by bulk contributions. In a new report now published on Science Advances, X. Sun and a research team in photonic technologies, physics and photonic metamaterials in Singapore and the U.K. showed how the chiral response of materials could be enhanced via nanostructuring. The tight confinement of electromagnetic fields in the resonant nanostructures enhanced the photoexcitation of spin-polarized surface states of a topological insulator to allow an 11-fold increase of the circular photogalvanic effect and a previously unobserved photocurrent dichroism at room temperature. Using this method, Sun et al. controlled the spin transport in topological materials via structural design, a hitherto unrecognized ability of metamaterials. The work bridges the gap between nanophotonics and spin electronics to provide opportunities to develop polarization-sensitive photodetectors.

Chirality

Chirality is a ubiquitous and fascinating natural phenomenon in nature, describing the difference of an object from its mirror image. The process manifests in a variety of scales and forms from galaxies to nanotubes and from organic molecules to inorganic compounds. Chirality can be detected at the atomic and molecular level in fundamental sciences, including chemistry, biology and crystallography, as well as in practice, such as in the food and pharmaceutical industry. To detect chirality, scientists can use interactions with electromagnetic fields, although the process can be hindered by a large mismatch between the wavelength of light and the size of most molecules at nanoscale dimensions. Designer metamaterials with structural features comparable to the wavelength of light can provide an independent approach to devise optical properties on demand to enhance the light-matter interaction to create and enhance the optical chirality of metamaterials. In this work, Sun et al.

Controversy has shrouded the once-common plasticizer BPA since studies started to highlight its links to a whole range of adverse health effects in humans, but recent research has also shown that its substitutes mightn’t be all that safe either. A new study has investigated how these compounds impact nerve cells in the adult brain, with the authors finding that they likely permanently disrupt signal transmission, and also interfere with neural circuits involved in perception.

BPA, or bisphenol A, is a chemical that has been commonly used in food, beverage and other types of packaging for decades, but experts have grown increasingly concerned that it can leech into these consumables and impact human health in ways ranging from endocrine dysfunction to cancer. This came on the back of scientific studies revealing such links dating back to the 1990s, which in turn saw the rise of “BPA-free” plastics as a safer alternative.

One of those alternatives is bisphenol S (BPS), and while it allows plastic manufacturers to slap a BPA-free label on their packaging, more and more research is demonstrating that it mightn’t be much better for us. As just one example, a study last year showed through experiments on mice that just like BPA, BPS can alter the expression of genes in the placenta and likely fundamentally disrupt fetal brain development.

Food is big business.

In the U.S., the weight-loss industry is worth $78 billion.

Meat is worth $218 billion.

Circa 2017

Tomato peels and eggshells are used in a sustainable rubber that could be used to make car tires.

These plants suck metals from the soil at amazing rates. Scientists hope farming the plants could provide an environmentally-friendly alternative to mining.

In recent years, Western brands including Nestlé (NSRGY), Impossible and Beyond Meat (BYND) have tapped into a growing appetite for such food and drinks in the West. Now, they’re headed east, raising fresh funding to target growth in the region, rolling out products specifically created for Asian consumers and setting up new factories on the ground.

Milo chocolate milk has been hugely popular in Southeast Asia for decades. Now the breakfast and teatime favorite is about to get shaken up — the cocoa powder will be offered as a dairy-free, ready-made beverage.

The product is one of Nestlé’s newest plant-based inventions, and it will be launched in the region this week, the company told CNN Business. Starting Thursday, the drink will hit supermarkets in Malaysia, and the Swiss multinational plans to sell it in other countries soon. (The company already offers plant-based Milo in Australia and New Zealand, but in the traditional powder form.)

In a recent paper, Bell argues that the principles of Mario Kart—especially the parts of it that make it so addictive and fun for players—can serve as a helpful guide to create more equitable social and economic programs that would better serve farmers in low-resource, rural regions of the developing world. That’s because, even when you’re doing horribly in Mario Kart—flying off the side of Rainbow Road, for example—the game is designed to keep you in the race.

“Farming is an awful thing to have to do if you don’t want to be a farmer,” Bell says. “You have to be an entrepreneur, you have to be an agronomist, put in a bunch of labor…and in so many parts of the world people are farmers because their parents are farmers and those are the assets and options they had.” This is a common story that Bell has come across many times during research trips to Pakistan, Bangladesh, Cambodia, Malawi, and other countries in southern Africa, and is what largely inspired him to focus his research on policies that could aid in development.

In his new paper, Bell argues that policies that directly provide assistance to farmers in the world’s poorest developing regions could help reduce poverty overall, while increasing sustainable and environmentally friendly practices. Bell says the idea is a lot like the way that Mario Kart gives players falling behind in the race the best power-ups, designed to bump them towards the front of the pack and keep them in the race. Meanwhile, faster players in the front don’t get these same boosts, and instead typically get weaker powers, such as banana peels to trip up a racer behind them or an ink splat to disrupt the other players’ screens. This boosting principle is called “rubber banding,” and it’s what keeps the game fun and interesting, Bell says, since there is always a chance for you to get ahead.
