Over the weekend, China launched a satellite into low-earth orbit, the first step of a plan to provide global satellite internet to people who still don't have reliable access. From a report: Nearly 3.8 billion people are unconnected to the internet, and women and rural poor are particularly affected. The satellite, called Hongyun-1, took off at China's national launching site Jiuquan Satellite Launch Center on Saturday (Dec. 22). Hongyun-1, or "rainbow cloud," is the first of 156 satellites of the same name developed by state-owned spacecraft maker China Aerospace Science and Industry Corporation (CASIC). CASIC intends to launch all the Hongyun satellites by around 2022 to form a constellation that will improve internet access in remote parts of China, and eventually in developing countries, a plan first announced in 2016. Most of the satellites will operate 1,000 kilometers (620 miles) above the earth, far lower than satellites are typically placed. The project is "moving the internet currently on the ground into the sky," said Hou Xiufeng, a spokesperson for CASIC, "It's China's first true low-orbit communication satellite... The launch will greatly boost commercial space."Read Replies (0)

Sony, the biggest maker of camera chips used in smartphones, is boosting production of next-generation 3D sensors after getting interest from customers including Apple. From a report: The chips will power front- and rear-facing 3D cameras of models from several smartphone makers in 2019, with Sony kicking off mass production in late summer to meet demand, according to Satoshi Yoshihara, head of Sony's sensor division. Sony's bullish outlook for 3D cameras provides much needed optimism to the global smartphone industry, which is suffering a slowdown as consumers find fewer reasons to upgrade devices. The Tokyo-based company has started providing software toolkits to outside developers so they can experiment with the chips and create apps that generate models of faces for communication or virtual objects for online shopping. "Cameras revolutionized phones, and based on what I've seen, I have the same expectation for 3D," said Yoshihara, who has worked for more than a decade on wider industry adoption of cameras in smartphones. "The pace will vary by field, but we're definitely going to see adoption of 3D. I'm certain of it."Read Replies (0)

Late last week, a team of about 50 scientists, drillers, and support staff successfully punched through nearly 4,000 feet of ice to access an Antarctic subglacial lake for just the second time in human history. From a report: On Friday, the Subglacial Antarctic Lakes Scientific Access (SALSA) team announced they'd reached Lake Mercer after melting their way through an enormous frozen river with a high-pressure, hot-water drill. The multi-year effort to tap into the subglacial lake -- one of approximately 400 scientists have detected across Antarctica -- offers a rare opportunity to study the biology and chemistry of the most isolated ecosystems on Earth. The only other subglacial lake humans have drilled into -- nearby Lake Whillans, sampled in 2013 -- demonstrated that these extreme environments can play host to diverse microbial life. Naturally, scientists are stoked to see what they'll find lurking in Lake Mercer's icy waters. "We don't know what we'll find," John Priscu, a biogeochemist at Montana State University and chief scientist for SALSA, told Earther via satellite phone from the SALSA drill camp on the Whillans Ice Plain. "We're just learning, it's only the second time that this has been done."Read Replies (0)

Russell Lewis, writing for NPR: When Nancy Grace Roman was a child, her favorite object to draw was the moon. Her mother used to take her on walks under the nighttime sky and show her constellations, or point out the colorful swirls of the aurora. Roman loved to look up at the stars and imagine. Eventually, her passion for stargazing blossomed into a career as a renowned astronomer. Roman was one of the first female executives at NASA, where she served as the agency's first chief of astronomy. Known as the "Mother of Hubble," for her role in making the Hubble Space Telescope a reality, Roman worked at NASA for nearly two decades. She died on Dec. 25 at the age of 93.
Roman fought to earn her place in a field dominated by men, paving the path for future female scientists. She was born in Nashville, Tenn. in 1925 and organized an astronomy club in fifth grade. She attended high school in Baltimore, where she requested to take a second year of algebra instead of a fifth year of Latin. When she made the appeal, she recounted in a 2017 interview with NPR that the guidance counselor wasn't supportive of her dream to become a scientist.
Her efforts helped lead to the creation of the Hubble Space Telescope. In her role at NASA, Roman developed and planned the Hubble Space Telescope, which is famous for its stunning images of space. Because of the Hubble Space Telescope, scientists have been able to collect data and gain insight into even the most remote galaxies of the universe. The success of the project led to future space telescopes. Roman's work, however, reached far beyond just the Hubble Space Telescope. In an interview with NASA, Roman once stated that one of the highlights of her career was when she discovered the first indication that common stars were not all the same age.Read Replies (0)

Apple has for years been a premium brand that rarely, if ever discounted products. Every year, the company could raise prices on products, and consumers would not only happily pay, but stand in long lines for the privilege of doing so. From a report: So when Apple started putting misleading, but seemingly consumer-friendly posters in front of Apple Stores at the end of 2018 offering a new iPhone model for $300 off (with trade-in of your current phone), you know something different happened for the company this year. Consumers fought back. Many analysts have reported that in the wake of poorer-than-expected sales for this year's crop of iPhones, Apple cut back on production, including on the $1,100 iPhone XS Max, the $999 iPhone XS and the XR, the "budget" model that replaced the previous entry-level new phone, the $349 SE. The price for the XR (the one Apple is hawking discounts for): $749.
"This should be a wakeup call for Apple," says Daniel Ives, an analyst with Wedbush Securities. "They swung, and they really missed." The prices on the new phones are "far too high," says Terry Walton, a tourist from Auckland, New Zealand. He has an iPhone 7 and didn't even consider any of the X-series iPhones because it still works just fine. Upgrading "didn't enter my mind at all," he says. It wasn't just iPhones that got price hikes. Apple also upped the cost of the top-of-the-line iPad to $1,000 as well (or over $2,800 for a loaded model) and added $300 to the cost of the Mac Mini and new MacBook Air computers.Read Replies (0)

The reputation of the meat industry will sink to that of big tobacco unless it removes cancer-causing chemicals from processed products such as bacon and ham, a coalition of experts and politicians in UK warn this week. From a report: Led by Professor Chris Elliott, the food scientist who ran the UK government's investigation into the horse-meat scandal, and Dr Aseem Malhotra, a cardiologist, the coalition claims there is a "consensus of scientific opinion" that the nitrites used to cure meats produce carcinogens called nitrosamines when ingested. It says there is evidence that consumption of processed meats containing these chemicals results in 6,600 bowel cancer cases every year in the UK -- four times the fatalities on British roads -- and is campaigning for the issue to be taken as seriously as sugar levels in food.
"Government action to remove nitrites from processed meats should not be far away," Malhotra said. "Nor can a day of reckoning for those who dispute the incontrovertible facts. The meat industry must act fast, act now -- or be condemned to a similar reputational blow to that dealt to tobacco." [...] In a statement issued today, the coalition warns "that not enough is being done to raise awareness of nitrites in our processed meat and their health risks, in stark contrast to warnings regularly issued regarding sugar and fattening foods."Read Replies (0)

In late 1966, a 29-year-old computer scientist drew a series of abstract figures on tracing paper and a quadrille pad. Some resembled a game of cat's cradle; others looked like heavenly constellations; still others like dress patterns. Those curious drawings were the earliest topological maps of what we now know as the internet. The doodler, Lawrence G. Roberts, died on Dec. 26 at his home in Redwood City, Calif. He was 81.
The New York Times: The cause was a heart attack, said his son Pasha. As a manager at the Pentagon's Advanced Research Projects Agency, or ARPA, Dr. Roberts designed much of the Arpanet -- the internet's precursor -- and oversaw its implementation in 1969. Dr. Roberts called upon a circle of colleagues who shared his interest in computer networking for help in creating the technical underpinnings of the Arpanet, integrating and refining many ideas for how data should flow. Dr. Roberts was considered the decisive force behind packet switching, the technology that breaks data into discrete bundles that are then sent along various paths around a network and reassembled at their destination. He decided to use packet switching as the underlying technology of the Arpanet; it remains central to the function of the internet.
And it was Dr. Roberts's decision to build a network that distributed control of the network across multiple computers. Distributed networking remains another foundation of today's internet. Dr. Roberts's interest in computer networking began when he was a graduate student at the Massachusetts Institute of Technology in the early 1960s. He paid close attention to the work of his longtime colleague, Leonard Kleinrock, who had done research on theoretical aspects of computer networks, analyzing the problem of data flow. Dr. Roberts also followed the ideas of J.C.R. Licklider, a prominent psychologist and predecessor of Dr. Roberts's at ARPA, who envisioned what he called an "intergalactic computer network."Read Replies (0)

Some of the most popular apps for Android smartphones, including Skyscanner, TripAdvisor and MyFitnessPal, are transmitting data to Facebook without the consent of users in a potential breach of EU regulations. From a report: In a study of 34 popular Android apps, the campaign group Privacy International found that at least 20 of them send certain data to Facebook the second that they are opened on a phone, before users can be asked for permission. Information sent instantly included the app's name, the user's unique ID with Google, and the number of times the app was opened and closed since being downloaded. Some, such as travel site Kayak, later sent detailed information about people's flight searches to Facebook, including travel dates, whether the user had children and which flights and destinations they had searched for. European law on data-sharing changed in May with the introduction of General Data Protection Regulation and mobile apps are required to have the explicit consent of users before collecting their personal information.Read Replies (0)

An anonymous reader shared a report: Sam Schreiber was mid-shampoo at a Drybar blow-dry salon in Los Angeles when someone from the front desk approached her stylist with an emergency: a woman was trying to pay for her blow-out with cash. "There was this beat of silence," says Ms. Schreiber, 33 years old. "She literally brought $40." More and more businesses like Drybar don't want your money -- the paper kind at least. It's making things awkward for those who come ill prepared. After all, you can't give back a hairdo, an already dressed salad or the two beers you already drank. The salad chain Sweetgreen has stopped accepting cash in nearly all its locations.
Most Dig Inns -- which serve locally sourced, healthy fast food -- won't take your bills either. Starbucks went cashless at a Seattle location in January, and at some pubs in the U.K., you can no longer get a pint with pound notes. The practice of not accepting cash has become popular enough to catch the attention of American lawmakers. [...] Despite the popularity of debit- and credit-card transactions, plenty of people do still pay for things with actual money. Cash represented 30% of all transactions and 55% of those under $10, according to a Federal Reserve survey of 2,800 people conducted in October 2017.Read Replies (0)

NASA's New Horizons spacecraft will visit a tiny and mysterious object in the Kuiper belt on Tuesday, seeking clues to the formation of our cosmic neighborhood. From a report: In June 1983, newspaper headlines declared that NASA's Pioneer 10 spacecraft had left the solar system, crossing beyond the orbit of Neptune. It was the common view of the time: All of the solar system's big, interesting things -- the sun and the nine planets -- were behind Pioneer 10. Thirty-five years later, the Kuiper belt -- the region Pioneer 10 was just entering -- and the spaces beyond are perhaps the most fascinating parts of the solar system. In their vast, icy reaches are clues about how the sun and planets, including ours, coalesced out of gas and dust 4.5 billion years ago. Even farther out might be bodies the size of Mars or Earth, or even a larger one some astronomers call Planet Nine, and technological advances could usher in a new age of planetary discovery.
On Tuesday, New Horizons, the NASA spacecraft that snapped spectacular photographs of Pluto in 2015, will provide humanity with a close-up of one of these mysterious, distant and tiny icy worlds. Its target of exploration is believed to be just 12 to 22 miles wide, known as 2014 MU69 -- its designation in the International Astronomical Union's catalog of worlds -- or Ultima Thule, the nickname bestowed upon it by the New Horizons team. This will be the farthest object ever visited by a spacecraft. New Horizons will speed past Ultima Thule at 31,500 miles per hour and pass within 2,200 miles of the surface. What the probe finds could reveal much about the earliest days of the solar system and what else lies in the Kuiper belt.Read Replies (0)
