Tesla sent out the first “Full Self-Driving” beta software update to a select group of customers this week, with the goal of a “wide release” by the end of the year. Tesla “has been focused on a fundamental architectural rewrite of our neural networks and control algorithms.” This rewrite will allow Tesla’s vehicles to interpret their environment in four dimensions rather than two, which should result in a dramatic improvement in performance and faster software updates. The company has yet to allow its customers hands-off control of the vehicle at medium speeds, where they are more likely to encounter traffic signals, intersections, and other complexities.
Researchers have now designed a stretchable, skin-like device that can be attached to a patient’s face and can measure small movements such as a twitch or a smile. Using this approach, patients could communicate a variety of sentiments, such as “I love you” or “I’m hungry,” with small movements that are measured and interpreted by the device. The researchers hope that their new device would allow patients to communicate in a more natural way, without having to deal with bulky equipment. The wearable sensor is thin and can be camouflaged with makeup to match any skin tone, making it unobtrusive.
This white paint could reduce the need for air conditioning by keeping surfaces cooler than surroundings
Engineers have created white paint that can keep surfaces up to 18 degrees Fahrenheit cooler than their ambient surroundings. The paint would replace the need for air conditioning by absorbing nearly no solar energy and sending heat away from the building. The paint would not only send heat away from a surface, but also away from Earth into deep space where heat travels indefinitely at the speed of light. “We’re not moving heat from the surface to the atmosphere. We’re just dumping it all out into the universe, which is an infinite heat sink.” The white paint created reflects 95.5% sunlight and efficiently radiates infrared heat.
The diabolical ironclad beetle, equipped with super-tough body armour, can withstand forces up to 39,000 times its body weight. The beetle, having lost the ability to fly away from danger, has evolved crush-resistant forewings (known as elytra), to survive being pecked to death by hungry birds. The researchers used microscopy, spectroscopy and mechanical testing, to identify a series of interlocked jigsaw-shaped joints within the exoskeleton. The scientists made a series of joints from metal and composites based on those seen in the beetle. They say their designs enhanced the strength and toughness of the materials.
Coca-Cola is saying goodbye to 200 brands, or half of its portfolio. Reducing the portfolio will allow Coca-Cola to focus on its most profitable offerings, the company explained. Those include its core products like Coca-Cola Zero Sugar as well as brandsthat fit into trendy new categories, like Topo Chico hard seltzer and AHA, a caffeinated seltzer. The underperforming beverages have “little to no scale,” and that their sales represent only 2% of total revenue. Culling the brands is one of a number of strategies the company laid out this summer to help it grow.Coke says the move will free up resources to invest in higher-growth drinks.
China’s Ant Group has won the final nod from the country’s top securities watchdog for the registration of its Shanghai offering clearing the last regulatory hurdle for its $35 billion dual-listing. The listing could be the world’s largest initial public offering, surpassing the record set by Saudi Aramco’s $29.4 billion. The fintech group aims to split the share offering evenly between Hong Kong and Shanghai, selling up to 1.67 billion on each exchange, targeting a valuation of $250 billion or more. Proceeds will be used partly to support Ant’s digital economy business and to enhance its research and development capabilities.
South Koreans are facing a shortage of a beloved dietary staple after a summer of extreme weather destroyed crops of cabbages – the main ingredient of kimchi. In what is being described a full-blown crisis, fields of Napa, or Chinese cabbages were wiped out in August and September, when the Korean peninsula was struck by typhoons, floods and landslides, sparking a sudden spike in the vegetable’s price. Kimchi is an indispensable part of the Korean diet, with South Koreans eating more than 2m tonnes every year. There are an estimated 200 varieties.
Wikipedia and the World Health Organization (WHO) have joined hands to stop the spread of false information. The WHO will grant Wikipedia free use of its published information, videos, and graphics about COVID-19. Under the agreement, the first WHO items uploaded on Wikimedia Commons are infographics that debunk dozens of myths about Coronavirus infection. If this works out to reduce the amount of false information spread across the society then the agency will consider countering misinformation related to HIV AIDS, Ebola, polio, and other diseases.
