Astronomers Have Come Up With a Better Way To Weigh Millions of Solitary Stars

Science_afficionado writes: By measuring the flicker pattern of light from distant stars, astronomers have developed a new and improved method for measuring the masses of millions of solitary stars, especially those hosting exoplanets. Stevenson Professor of Physics and Astronomy Keivan Stassun says, “First, we use the total light from the star and its parallax to infer its diameter. Next, we analyze the way in which the light from the star flickers, which provides us with a measure of its surface gravity. Then we combine the two to get the star’s total mass.” Stassun and his colleagues describe the method and demonstrate its accuracy using 675 stars of known mass in an article titled “Empirical, accurate masses and radii of single stars with TESS and GAIA” accepted for publication in the Astronomical Journal.

David Salisbury via Vanderbilt University explains the other methods of determining the mass of distant stars, and why they aren’t always the most accurate: “Traditionally, the most accurate method for determining the mass of distant stars is to measure the orbits of double star systems, called binaries. Newton’s laws of motion allow astronomers to calculate the masses of both stars by measuring their orbits with considerable accuracy. However, fewer than half of the star systems in the galaxy are binaries, and binaries make up only about one-fifth of red dwarf stars that have become prized hunting grounds for exoplanets, so astronomers have come up with a variety of other methods for estimating the masses of solitary stars. The photometric method that classifies stars by color and brightness is the most general, but it isn’t very accurate. Asteroseismology, which measures light fluctuations caused by sound pulses that travel through a star’s interior, is highly accurate but only works on several thousand of the closest, brightest stars.” Stassun says his method “can measure the mass of a large number of stars with an accuracy of 10 to 25 percent,” which is “far more accurate than is possible with other available methods, and importantly it can be applied to solitary stars so we aren’t limited to binaries.”

Alphabet Swaps Project Loon Balloons for ‘Boxes’ to Bring Light Beam Internet to India

One of Alphabet’s crazier attempts to bring the internet to more rural and isolated areas was Project Loon. Using what is called Free Space Optical Communication (FSOC), Alphabet has sought to prove it’s possible to reliably send data wirelessly between balloons floating thousands of feet in the sky. However, the task…

A Cryptocurrency Without a Blockchain Has Been Built To Outperform Bitcoin

An anonymous reader quotes a report from MIT Technology Review: Bitcoin isn’t the only cryptocurrency on a hot streak — plenty of alternative currencies have enjoyed rallies alongside the Epic Bitcoin Bull Run of 2017. One of the most intriguing examples is also among the most obscure in the cryptocurrency world. Called IOTA, it has jumped in total value from just over $4 billion to more than $10 billion in a little over two weeks. But that isn’t what makes it interesting. What makes it interesting is that it isn’t based on a blockchain at all; it’s something else entirely. The rally began in late November, after the IOTA Foundation, the German nonprofit behind the novel cryptocurrency, announced that it was teaming up with several major technology firms to develop a “decentralized data marketplace.”

Though IOTA tokens can be used like any other cryptocurrency, the protocol was designed specifically for use on connected devices, says cofounder David Sonstebo. Organizations collect huge amounts of data from these gadgets, from weather tracking systems to sensors that monitor the performance of industrial machinery (a.k.a. the Internet of things). But nearly all of that information is wasted, sitting in siloed databases and not making money for its owners, says Sonstebo. IOTA’s system can address this in two ways, he says. First, it can assure the integrity of this data by securing it in a tamper-proof decentralized ledger. Second, it enables fee-less transactions between the owners of the data and anyone who wants to buy it — and there are plenty of companies that want to get their hands on data. The report goes on to note that instead of using a blockchain, “IOTA uses a ‘tangle,’ which is based on a mathematical concept called a directed acyclic graph.” The team decided to research this new alternative after deciding that blockchains are too costly. “Part of Sonstebo’s issue with Bitcoin and other blockchain systems is that they rely on a distributed network of ‘miners’ to verify transactions,” reports MIT Technology Review. “When a user issues a transaction [with IOTA], that individual also validates two randomly selected previous transactions, each of which refer to two other previous transactions, and so on. As new transactions mount, a ‘tangled web of confirmation’ grows, says Sonstebo.”

Noninvasive Radiation Therapy Halts Deadly Heart Rhythm

schwit1 shares a report from The New York Times (Warning: source may be paywalled; alternative source): The patients were gravely ill, their hearts scarred by infections or heart attacks. In each, the electrical system that maintains a regular heartbeat had been short-circuited. They suffered frequent bursts of rapid heartbeats, which can end in sudden death. The condition kills an estimated 325,000 Americans each year, the most common cause of death in this country. And these people had exhausted all conventional treatments. So researchers at Washington University in St. Louis offered the patients something experimental: short bursts of radiation aimed at their hearts in an effort to obliterate the cells that were causing the electrical malfunctions. Results in the first five patients were published on Thursday in the New England Journal of Medicine, and the experiment seems to have worked — offering hope to similar patients everywhere who have had no alternatives except a heart transplant. The treatment requires weeks to take full effect, so it cannot be used for cardiac patients who need immediate help. And the method must be studied in larger groups of patients over longer times, an effort that has already begun.

DOJ Confirms Uber Is Being Investigated For Criminal Behavior

A newly released letter from the Department of Justice has formally acknowledged that federal prosecutors have an open criminal investigation into Uber. Ars Technica reports: Late last month, as part of the proceedings in the high-profile and ongoing Waymo v. Uber trade secrets lawsuit, U.S. District Judge William Alsup said that on November 22 he had received a letter from San Francisco-based federal prosecutors. It is very unusual for a judge in a civil case to be apprised of a pending criminal investigation involving one of the litigants. In a separate November 28 letter sent to Judge Alsup, Acting U.S. Attorney Alex Tse asked that the first letter not be made public. The judge unsealed both letters on Wednesday. The first letter was signed by two prosecutors, Matthew Parrella and Amie Rooney. Those attorneys are assigned to the Computer Hacking and Intellectual Property (CHIP) Unit at the United States Attorney’s Office in San Jose. [T]he letter could mean Uber and/or its current or former employees may be under investigation for possible crimes under the Computer Fraud and Abuse Act, a longstanding anti-hacking law.

Facebook Will Introduce Ads As Videos Start Playing

Facebook is going to start running pre-roll ads on its “Watch” videos next year. While you won’t see your News Feed full of video ads, you will start to see pre-rolls, which will run for up to six seconds, on videos in Facebook’s “Watch” hub. Recode reports: Facebook launched its Watch hub earlier this year, using “mid-roll” ads (another ad format Facebook tried to avoid for a long time). The fact that they have added pre-rolls — the format used around the web and the one advertisers are most comfortable with — should be read as an admission that the mid-roll ads aren’t generating significant revenue for Facebook or the publishers putting video into Watch. Speaking of those mid-roll ads: Facebook now says they won’t appear until later in videos and they’ll only run on longer videos. It says the ads (it calls them “ad breaks”) can’t run until a minute into a video, and they can only run if the video is at least three minutes long. At first, the ads could run after 20 seconds and on videos as short as 90 seconds.
