Following the inauguration of President Biden, the White House website received a major update. The website includes information about the current administration and the history of the White House but hidden in its code is a secret invitation for people to apply for a job in technology. If you use the developer tools on your browser to inspect the website, you’ll see a hidden message that states, “If you’re reading this, we need your help building back better.” It then has the text for the United States Digital Service (USDS) job application page. The USDS is a technology unit that works across the U.S. federal government to improve services.
Apple’s first crack at a headset is designed to be a pricey, niche precursor to a more ambitious augmented reality product that will take longer to develop. As a mostly virtual reality device, it will display an all-encompassing 3-D digital environment for gaming, watching video and communicating. AR functionality, the ability to overlay images and information over a view of the real world, will be more limited. Apple has planned to launch the product as soon as 2022. The company is building a high-end, niche product that will prepare outside developers and consumers for its eventual, more mainstream AR glasses.
People who follow a low-carb diet consume more calories on average than those who follow a low-fat diet, although both diets can result in similar levels of total weight loss. People on the low-fat diet consumed fewer calories and lost body fat at a higher rate than people who followed the low-carb diet. However, those on the low-carb diet experienced less variability in blood sugar and insulin levels after meals. “If you think your insulin surges are particularly harmful, then the ketogenic diet might be for you. If you’re worried about triglyceride [a constituent of fat] levels in your blood going up too high after meals, then clearly the low-fat diet was better.”
Researchers have developed a phototherapy technology that can significantly increase efficiency while reducing the pain of chemotherapy and minimizing side effects after treatment. The research team developed a peptide-based photosensitizer that activates phototherapeutic effects only in cancer tissues. When this newly developed photosensitizer is injected into a living body, it is activated by the body temperature and aggregates into a supramolecular arrangement designed by the research team, to be stored around the tumor. The subsequent phototherapy can destroy only cancer cells without affecting surrounding normal cells.
American Airlines is hoping to sell and ship some of its excesswine directly to peoples’ homes. The company said that a new program – called American Airlines Flagship Cellars – will give customers a chance to buy wine by the bottle, in custom “curated” cases, or via a monthly subscription plan that costs $99 per month. American Airlines’ single-bottle wine offerings range in price from about $13 to $40, and the most expensive offering is a $300 three-pack of Champagne. The wine bottles are among those that would have been served to customers with American Airlines’ “Flagship” tickets, a luxury seating option on international and transcontinental flights.
Earth observation company Satellogic announced Jan. 19 it signed a contract with SpaceX covering several rideshare launches of its satellites through next year. The multiple launch services agreement makes SpaceX Satellogic’s preferred provider for launching its constellation of microsatellites. Emiliano Kargieman, chief executive of Satellogic, said the low prices and frequent launch opportunities that SpaceX offered led his company to sign up. “The new rideshare program that SpaceX has put together has reduced the price on the order of four or five times on a per-kilogram basis,” he said.
In an epic cleanup effort, volunteers removed more than 9,000 pounds of trash from the Tennessee River, one of the dirtiest rivers in the country. Over the course of three days earlier this month, volunteers with Keep the Tennessee River Beautiful and Johnsonville State Historic Park rid the river of 9,208 pounds of trash, using a 25-foot aluminum work boat to traverse the river and clean shorelines. “That’s how the change for our river will happen: through local partners and individuals who are eager about taking ownership to protect and improve their beautiful river community.”
Egypt’s cabinet has toughened a law banning female genital mutilation (FGM) – imposing jail terms of up to 20 years as part of efforts to stamp out the ancient practice. Nearly 90% of Egyptian women and girls aged between 15 and 49 have undergone FGM, according to a 2016 survey by the U.N. Children’s Fund (UNICEF), and the ritual is practised widely by both Muslims and Christians despite the 2008 ban.
