sciencehabit shares a report from Science Magazine: SpaceX CEO Elon Musk grabbed the world's attention last week after launching his Tesla Roadster into space. But his publicity stunt has a half-life way beyond even what he could imagine -- the Roadster should continue to orbit through the solar system, perhaps slightly battered by micrometeorites, for a few tens of millions of years. Now, a group of researchers specializing in orbital dynamics has analyzed the car's orbit for the next few million years. And although it's impossible to map it out precisely, there is a small chance that one day it could return and crash into Earth. But don't panic: That chance is just 6% over a million years, and it would likely burn up as it entered the atmosphere.
Hanno Rein of the University of Toronto in Canada and his colleagues regularly model the motions of planets and exoplanets. "We have all the software ready, and when we saw the launch last week we thought, 'Let's see what happens.' So we ran the [Tesla's] orbit forward for several million years," he says. The Falcon Heavy rocket from SpaceX propelled the car out toward Mars, but the sun's gravity will bring it swinging in again some months from now in an elliptical orbit, so it will repeatedly cross the orbits of Mars, Earth, and Venus until it sustains a fatal accident. The Roadster's first close encounter with Earth will be in 2091 -- the first of many in the millennia to come.Read Replies (0)

According to media reports, Apple is planning to postpone some new features for iOS and macOS this year to focus on improving reliability, stability and performance of the existing versions. Steven Sinofsky, a former President of the Windows Division, shared his insights into the significance of this development: Several important points are conflated in the broad discussion about Apple and software: Quality, pace of change, features "versus" quality, and innovation. Scanning the landscape, it is important to recognize that in total the work Apple has been doing across hardware, software, services, and even AI/ML, in total -- is breathtaking and unprecedented in scope, scale, and quality. Few companies have done so much for so long with such a high level of consistency. This all goes back to the bet on the NeXT code base and move to Intel for Mac OS plus the iPod, which began the journey to where we are today. [...] What is lost in all of this recent discussion is the nuance between features, schedule, and quality. It is like having a discussion with a financial advisor over income, risk, and growth. You don't just show up and say you want all three and get a "sure." On the other hand, this is precisely what Apple did so reliably over 20 years. But behind the scenes there is a constant discussion over balancing these three legs of the tripod. You have to have all of them but you "can't" but you have to. This is why they get paid big $. [...] A massive project like an OS (+h/w +cloud) is like a large investment portfolio and some things will work (in market) and others won't, some things are designed to return right away, some are safe bets, some are long term investments. And some mistakes... Customers don't care about any of that and that's ok. They just look for what they care about. Each evaluates through their own lens. Apple's brilliance is in focusing mostly on two audiences -- Send-users and developers -- tending to de-emphasize the whole "techie" crowd, even IT. When you look at a feature like FaceID and trace it backwards all the way to keychain -- see how much long term thought can go into a feature and how much good work can go unnoticed (or even "fail") for years before surfacing as a big advantage. That's a long term POV AND focus. This approach is rather unique compared to other tech companies that tend to develop new things almost independent of everything else. So new things show up and look bolted on the side of what already exists. (Sure Apple can do that to, but not usually). All the while while things are being built the team is just a dev team and trying to come up with a reliable schedule and fix bug. This is just software development.Read Replies (0)

Fast Company: Facebook unveiled this kid-friendly version of its signature messaging service in December, while the YouTube Kids scandal was in full swing. Messenger Kids, Facebook said, had been designed to serve as a "fun, safer solution" for family communications. It would be available for children as young as 6, the company said. To forestall criticism, Facebook asserted that the app had been developed alongside thousands of parents and a dozen expert advisors. But it looks like many of those outside experts were funded with Facebook dollars. According to Wired, "At least seven members of Facebook 13-person advisory board have some kind of financial tie to the company." Those advisors include the National PTA, Blue Star Families, Connect Safely, and the Yale Center for Emotional Intelligence.Read Replies (0)

Google is enabling its built-in ad blocker for Chrome tomorrow (February 15th). From a report: Chrome's ad filtering is designed to weed out some of the web's most annoying ads, and push website owners to stop using them. Google is not planning to wipe out all ads from Chrome, just ones that are considered bad using standards from the Coalition for Better Ads. Full page ads, ads with autoplaying sound and video, and flashing ads will be targeted by Chrome's ad filtering, which will hopefully result in less of these annoying ads on the web. Google is revealing today exactly what ads will be blocked, and how the company notifies site owners before a block is put in place. On desktop, Google is planning to block pop-up ads, large sticky ads, auto-play video ads with sound, and ads that appear on a site with a countdown blocking you before the content loads. Google is being more aggressive about its mobile ad blocking, filtering out pop-up ads, ads that are displayed before content loads (with or without a countdown), auto-play video ads with sound, large sticky ads, flashing animated ads, fullscreen scroll over ads, and ads that are particularly dense.Read Replies (0)

An anonymous reader shares an excerpt from a report via TechCrunch, written by Devin Coldewey: Google just announced a plan to "modernize" email with its Accelerated Mobile Pages platform, allowing "engaging, interactive, and actionable email experiences." Does that sound like a terrible idea to anyone else? It sure sounds like a terrible idea to me, and not only that, but an idea borne out of competitive pressure and existing leverage rather than user needs. Not good, Google. Send to trash. See, email belongs to a special class. Nobody really likes it, but it's the way nobody really likes sidewalks, or electrical outlets, or forks. It not that there's something wrong with them. It's that they're mature, useful items that do exactly what they need to do. They've transcended the world of likes and dislikes. Email too is simple. It's a known quantity in practically every company, household, and device. The implementation has changed over the decades, but the basic idea has remained the same since the very first email systems in the '60s and '70s, certainly since its widespread standardization in the '90s and shift to web platforms in the '00s. The parallels to snail mail are deliberate (it's a payload with an address on it) and simplicity has always been part of its design (interoperability and privacy came later). No company owns it. It works reliably and as intended on every platform, every operating system, every device. That's a rarity today and a hell of a valuable one.

schwit1 shares a report from Space.com: This isn't your average timekeeper. The so-called Deep Space Atomic Clock (DSAC) is far smaller than Earth-bound atomic clocks, far more precise than the handful of other space-bound atomic clocks, and more resilient against the stresses of space travel than any clock ever made. According to a NASA statement, it's expected to lose no more than 2 nanoseconds (2 billionths of a second) over the course of a day. That comes to about 7 millionths of a second over the course of a decade. n an email to Live Science, Andrew Good, a Jet Propulsion Laboratory representative, said the first DSAC will hitch a ride on the second Falcon Heavy launch, scheduled for June. Every deep-space mission that makes course corrections needs to send signals to ground stations on Earth. Those ground stations rely on atomic clocks to measure just how long those signals took to arrive, which allows them to locate the spacecrafts position down to the meter in the vast vacuum. They then send signals back, telling the craft where they are and where to go next. Thats a cumbersome process, and it means any given ground station can support only one spacecraft at a time. The goal of DSAC, according to a NASA fact sheet, is to allow spacecraft to make precise timing measurements onboard a spacecraft, without waiting for information from Earth. A DSAC-equipped spacecraft, according to NASAs statement, could calculate time without waiting for measurements from Earth -- allowing it to make course adjustments or perform precision science experiments without pausing to turn its antennas earthward and waiting for a reply.Read Replies (0)

An anonymous reader quotes a report from Scientific American: Clostridium difficile, a deadly bacterium spread by physical contact with objects or infected people, thrives in hospitals, causing 453,000 cases a year and 29,000 deaths in the United States, according to a 2015 study in the New England Journal of Medicine. Traditional methods such as monitoring hygiene and warning signs often fail to stop the disease. But what if it were possible to systematically target those most vulnerable to C-diff? Erica Shenoy, an infectious-disease specialist at Massachusetts General Hospital, and Jenna Wiens, a computer scientist and assistant professor of engineering at the University of Michigan, did just that when they created an algorithm to predict a patient's risk of developing a C-diff infection, or CDI. Using patients' vital signs and other health records, this method -- still in an experimental phase -- is something both researchers want to see integrated into hospital routines.
The CDI algorithm -- based on a form of artificial intelligence called machine learning -- is at the leading edge of a technological wave starting to hit the U.S. health care industry. After years of experimentation, machine learning's predictive powers are well-established, and it is poised to move from labs to broad real-world applications, said Zeeshan Syed, who directs Stanford University's Clinical Inference and Algorithms Program. Shenoy and Wiens' CDI algorithm analyzed a data set from 374,000 inpatient admissions to Massachusetts General Hospital and the University of Michigan Health System, seeking connections between cases of CDI and the circumstances behind them. The records contained over 4,000 distinct variables. As it repeatedly analyzes this data, the ML process extracts warning signs of disease that doctors may miss -- constellations of symptoms, circumstances and details of medical history most likely to result in infection at any point in the hospital stay.Read Replies (0)

New York Times CEO Mark Thompson believes that the newspaper printing presses may have another decade of life in them, but not much more. "I believe at least 10 years is what we can see in the U.S. for our print products," Thompson said on "Power Lunch." He said he'd like to have the print edition "survive and thrive as long as it can," but admitted it might face an expiration date. "We'll decide that simply on economics," he said. "There may come a point when the economics of [the print paper] no longer make sense for us. The key thing for us is that we're pivoting. Our plan is to go on serving our loyal print subscribers as long as we can. But meanwhile to build up the digital business, so that we have a successful growing company and a successful news operation long after print is gone." CNBC reports: Digital subscriptions, in fact, may be what's keeping the New York Times afloat for a new generation of readers. While Thompson said the number of print subscribers is relatively constant, "with a little bit of a decline every time," the company said last week that it added 157,000 digital subscribers in the fourth quarter of 2017. The majority were new subscribers, but that number also included cooking and crossword subscriptions. Revenue from digital subscriptions increased more than 51 percent in the quarter compared with a year earlier. Overall subscription revenue increased 19.2 percent. Meanwhile, the company's fourth-quarter earnings and revenue beat analysts expectations, "even though the print side of the business is still somewhat challenged," Thompson said. Total revenue rose 10 percent from a year earlier to $484.1 million. New York Times' shares have risen more than 20 percent this year. "Without question we make more money on a print subscriber," Thompson added. "But the point about digital is that we believe we can grow many, many more of them. We've already got more digital than print subscribers. Digital is growing very rapidly. Ultimately, there will be many times the number of digital subscribers compared to print."Read Replies (0)
