Studies Show Testosterone Offers Little Benefits To Aging Men (arstechnica.com) 7

An anonymous reader quotes a report from Ars Technica: In decades of research, scientists have found only one medical condition that's clearly and effectively treated with testosterone supplements: pathological hypogonadism -- that's low testosterone levels due to disease of the hypothalamus, pituitary gland, or testes. In a series of placebo-controlled, randomized trials, researchers tracked the effect of testosterone on the cognition, bone health, anemia, and cardiovascular health of 788 men for a year. All the men were aged 65 or older and had low testosterone levels that couldn't be explained by anything other than age. The results, reported Tuesday in JAMA and JAMA Internal Medicine, offer mixed results. Among the 493 in the trial who also had age-related memory declines, testosterone didn't have any effect on memory or cognitive abilities. In the study, 247 got testosterone and 246 got a placebo. But for cardiovascular health, there was an effect -- a bad one. Over the year, plaque buildup in the coronary artery -- which is a risk factor for heart disease -- increased in 73 men on testosterone compared with 65 on placebo. However, other studies have found mixed results on this. Longer, bigger trials will be needed to sort out the risks. In the anemia study, testosterone did seem to improve iron levels in men with mild anemia. The bone health study also showed that testosterone could improve bone density. However, it's unclear if those benefits outweigh the possible cardiovascular risks. And other drugs may be more effective at treating anemia and improving bone mass than testosterone.

Cellphones As a Fifth-Order Elaboration of Maxwell's Theory (ieee.org) 40

schwit1 shares a report from IEEE Spectrum that reflects on the "Stages of Electronics" based on James Clerk Maxwell's theory: Now that the world has become addicted to portable electronics, billions of people have come to see the companies providing these gadgets as the most innovative, and the people who head those companies as the most exalted, of all time. "Genius" is a starter category in this discussion. But clever and appealing though today's electronic gadgets may be, to the historian they are nothing but the inevitable fifth-order elaborations of two fundamental ideas: electromagnetic radiation, the theory of which was formulated by James Clerk Maxwell in the 1860s, and miniaturized fabrication, which followed Richard Feynman's 1959 dictum [PDF] that "there's plenty of room at the bottom." Maxwell was a true genius. The history of science offers few examples of work as brilliant as unifying electricity, magnetism, and light as aspects of a single phenomenon: electromagnetic waves. As Max Planck put it, "in doing so he achieved greatness unequalled."

Vaclav Smil writes via IEEE: "As I pass the zombielike figures on the street, oblivious to anything but their cellphone screens, I wonder how many of them know that the most fundamental advances enabling their addictions came not from Nokia, Apple, Google, Samsung, or LG. These companies' innovations are certainly admirable, but they amount only to adding a few fancy upper floors to a magnificent edifice whose foundations were laid by Maxwell 152 years ago and whose structure depends on decades-old advances that made it possible to build electronics devices ever smaller."

The Only Thing, Historically, That's Curbed Inequality: Catastrophe (theatlantic.com) 196

ColdWetDog writes: The Atlantic has an interesting article on how societies have decreased economic equality. From the report: "Calls to make America great again hark back to a time when income inequality receded even as the economy boomed and the middle class expanded. Yet it is all too easy to forget just how deeply this newfound equality was rooted in the cataclysm of the world wars. The pressures of total war became a uniquely powerful catalyst of equalizing reform, spurring unionization, extensions of voting rights, and the creation of the welfare state. During and after wartime, aggressive government intervention in the private sector and disruptions to capital holdings wiped out upper-class wealth and funneled resources to workers; even in countries that escaped physical devastation and crippling inflation, marginal tax rates surged upward. Concentrated for the most part between 1914 and 1945, this 'Great Compression' (as economists call it) of inequality took several more decades to fully run its course across the developed world until the 1970s and 1980s, when it stalled and began to go into reverse. This equalizing was a rare outcome in modern times but by no means unique over the long run of history. Inequality has been written into the DNA of civilization ever since humans first settled down to farm the land. Throughout history, only massive, violent shocks that upended the established order proved powerful enough to flatten disparities in income and wealth. They appeared in four different guises: mass-mobilization warfare, violent and transformative revolutions, state collapse, and catastrophic epidemics. Hundreds of millions perished in their wake, and by the time these crises had passed, the gap between rich and poor had shrunk."

Slashdot reader ColdWetDog notes: "Yep, the intro is a bit of a swipe at Trump. But this should get the preppers and paranoids in the group all wound up. Grab your foil! Run for the hills!"

College Senior Turns His Honda Civic Into a Self-Driving Car Using Free Hardware, Software (technologyreview.com) 70

holy_calamity writes: University of Nebraska student Brevan Jorgenson swapped the rear-view mirror in his 2016 Honda Civic for a home-built device called a Neo, which can steer the vehicle and follow traffic on the highway. Jorgenson used hardware designs and open-source software released by Comma, a self-driving car startup that decided to give away its technology for free last year after receiving a letter asking questions about its functionality from the National Highway Traffic Safety Administration (NHTSA). Jorgenson is just one person in a new hacker community trying to upgrade their cars using Comma's technology. "A Neo is built from a OnePlus 3 smartphone equipped with Comma's now-free Openpilot software, a circuit board that connects the device to the car's electronics, and a 3-D-printed case," reports MIT Technology Review. The report notes that Neodriven, a startup based in Los Angeles, has recently started selling a pre-built Neo device that works with Comma's Openpilot software, but it costs $1,495.

Valve's Gabe Newell Says Only 30 SteamVR Apps Have Made $250,000+ (roadtovr.com) 75

New submitter rentarno writes: According to Valve President, Gabe Newell, only 30 virtual-reality apps on Steam (of some 1,000) have made more than $250,000. But that isn't stopping the company from throwing the bulk of their weight behind virtual reality; Valve recently confirmed that it's working on 3 full VR games. Valve still believes in a huge future for VR, even while things are slow to start. It'll take work to find and make the content that's great for VR, Newell says. "We got Half-Life 2 and Team Fortress running in VR. It was kind of a novelty, purely a development milestone. There was absolutely nothing compelling about them. Nobody's going to buy a VR system so they can watch movies. You have to aspire and be optimistic that the unique characteristics of VR will cause you to discover a bunch of stuff that isn't possible on any of the existing platforms." How do you view the VR industry in early 2017? Do you think it shows promise or will eventually fail like 3D TV?

Samsung To Sell Refurbished Galaxy Note 7 With a Smaller Battery, Says Report (androidauthority.com) 48

According to a report via The Korean Economic Daily, Samsung is said to be putting refurbished Galaxy Note 7 handsets on sale with new batteries following the cancellation of the device late last year. The speculation suggests the smartphones could be relaunched this June. Android Authority reports: Samsung is said to be swapping the Note 7's 3,500 mAh batteries with a "3,000 to 3,200 mAh" batteries, according to The Korean Economic Daily's sources, predominately for sale in emerging markets such as India and Vietnam. The move is said to be part of Samsung's plan to recover costs from the initial device recall and avoid environmental penalties from the estimated 2.5 million or so Galaxy Note 7s it would have to dispose of. Samsung hasn't made any official announcements in this vein, but before the battery investigation concluded, a spokesperson did tell us that the company was: "Reviewing possible options that can minimize the environmental impact of the recall." Shifting refurbished units would certainly be one way to achieve that.

'We Won't Block Pirate Bay,' Swedish Telecoms Giant Says (torrentfreak.com) 18

Last week, a Swedish Patent and Market Court of Appeal ordered The Pirate Bay and streaming portal Swefilmer to be blocked by internet service provider Bredbandsbolaget for the next three years. The order was not well supported by other internet service providers in Sweden, as it appears they don't like the idea of becoming copyright policemen. TorrentFreak reports: Last week ISP Bahnhof absolutely slammed the decision to block The Pirate Bay, describing the effort as signaling the "death throes" of the copyright industry. It even hinted that it may offer some kind of technical solution to customers who are prevented from accessing the site. For those familiar with Bahnhof's stance over the years, this response didn't come as a surprise. The ISP is traditionally pro-freedom and has gone out of its way to make life difficult for copyright enforcers of all kinds. However, as one of the leading telecoms companies in Sweden and neighboring Norway, ISP Telia is more moderate. Nevertheless, it too says it has no intention of blocking The Pirate Bay, unless it is forced to do so by law. "No, we will not block if we are not forced to do so by a court," a company press officer said this morning. Telia says that the decision last week from the Patent and Market Court affects only Bredbandsbolaget, indicating that a fresh legal process will be required to get it to respond. That eventuality appears to be understood by the rightsholders but they're keeping their options open.

Wyden To Introduce Bill To Prohibit Warrantless Phone Searches At Border (onthewire.io) 126

Trailrunner7 quotes a report from On the Wire: A senator from Oregon who has a long track record of involvement on security and privacy issues says he plans to introduce a bill soon that would prevent border agents from forcing Americans returning to the country to unlock their phones without a warrant. Sen. Ron Wyden said in a letter to the secretary of the Department of Homeland Security that he is concerned about reports that Customs and Border Patrol agents are pressuring returning Americans into handing over their phone PINs or using their fingerprints to unlock their phones. DHS Secretary John Kelly has said that he's considering the idea of asking visitors for the login data for their various social media accounts, information that typically would require a warrant to obtain. "Circumventing the normal protection for such private information is simply unacceptable," Wyden said in the letter, sent Monday. "There are well-established procedures governing how law enforcement agencies may obtain data from social media companies and email providers. The process typically requires that the government obtain a search warrant or other court order, and then ask the service provider to turn over the user's data."

UPS Develops 'Rolling Warehouse' System In Which Drones Are Launched From Atop Trucks (bloomberg.com) 33

mi writes: A Bloomberg article describes a test conducted by UPS on Monday, "launching an unmanned aerial vehicle from the roof of a UPS truck about a quarter-mile to a blueberry farm outside Tampa, Florida. The drone dropped off a package at a home on the property, and returned to the truck, which had moved about 2,000 feet." The company is looking to design a "rolling warehouse" system in which a drone is "deployed from the roof of a UPS truck and flies at an altitude of 200 feet to the destination." It returns after dropping off the package while the truck is already on its way to the next stop.

PHP Becomes First Programming Language To Add 'Modern' Cryptography Library In Its Core (bleepingcomputer.com) 147

An anonymous reader writes from a report via BleepingComputer: The PHP team has unanimously voted to integrate the Libsodium library in the PHP core, and by doing so, becoming the first programming language to support a modern cryptography library by default. Developers approved a proposal with a vote of 37 to 0 and decided that Libsodium will be added to the upcoming PHP 7.2 release that will be launched towards the end of 2017. Scott Arciszewski, the cryptography expert who made the proposal, says that by supporting modern crypto in the PHP core, the PHP team will force the WordPress team to implement better security in its CMS, something they avoided until now. Additionally, it will allow PHP and CMS developers to add advanced cryptography features to their apps that run on shared hosting providers, where until now they weren't able to install custom PHP extensions to support modern cryptography. Other reasons on why he made the proposal are detailed here. Arciszewski also says that PHP is actually "the first" programming language to support a "modern" cryptography library in its core, despite Erlang and Go including similar libraries, which he claims are not as powerful and up-to-date as PHP's upcoming Libsodium implementation.

Health Apps Could Be Doing More Harm Than Good, Warn Scientists (theguardian.com) 73

According to several scientists, fitness apps might be doing more harm than good because they don't work but force people to focus on ambitious goals that they will never reach. Some are so appalled by these apps that they have called it "snake oil salesmen of the 1860s." From a report on The Guardian: Greg Hager, professor of computer science at Johns Hopkins University, said that in the absence of trials or scientific grounding it was impossible to say whether apps were having the intended effect. "I am sure that these apps are causing problems," he told the American Association for the Advancement of Science annual meeting in Boston. [...] Hager claimed the 10,000 steps target dated back to a 1960s Japanese study that showed there were health benefits for men who burned at least 2,000 calories per week through exercise -- roughly equivalent to 10,000 steps each day. An early pedometer was known as the manpo-kei, which means "10,000-step meter" in Japanese. "But is that the right number for any of you in this room?" Hager asked. "Who knows. It's just a number that's now built into the apps." "We have an incredible number of apps in the wild basically being downloaded by people who may or may not understand what they are actually telling them or what the context for that is," he said. "Until we have evidence-based apps you could amplify issues. I mean, imagine everyone thinks they have to do 10,000 steps but you are not actually physically capable of doing that, you could actually cause harm or damage by doing so."

Computer Glasses Claim To Protect Eyesight Are Selling Like Hotcakes, But They Probably Aren't Useful (businessinsider.in) 100

People are increasingly concerned that bright light -- especially "blue light" from computer screens -- is causing harm, making it a potentially dangerous public health issue. Eyewear and screen protector companies have been selling products they say can protect people from these harms. But are they really making any difference? From a report: We do know that blue light at night can interfere with sleep, causing a host of negative effects. But the evidence that the amount of light screen expose us to during the day is harmful is not really there. Furthermore, many experts think these products are unnecessary and could perhaps do more harm than good. [...] The research that companies selling blue-blocking products cite falls into three categories: animal studies, in vitro studies of retinal cells exposed to light, and studies of people exposed to outdoor light. [...] "I think it's largely hype, not science," says Dr. Richard Rosen, Director of Retina Services at New York Eye and Ear Infirmary of Mount Sinai and Ophthalmology Research Director at Icahn School of Medicine. "They want to sell it; they know people get uncomfortable staring at screens all day, so they say, it's because of this [blue light issue]." The report cites insight from several other doctors as well studies to make a case for why these glasses aren't useful.

Intel Supercharges Atom Chips With 16 Cores and Pro Level Features (pcworld.com) 56

Agam Shah, writing for PCWorld: Intel's Atom was mostly known as a low-end chip for mobile devices that underperformed. That may not be the case anymore. The latest Atom C3000 chips announced on Tuesday have up to 16 cores and are more sophisticated than ever. The chips are made for storage arrays, networking equipment, and internet of things devices. The new chips have features found mostly in server chips, including networking, virtualization, and error correction features. [...] A surprising feature in C3000 is RAS (reliability, availability, and serviceability) capabilities, which is mostly found on high-end Xeon chips. The feature corrects data errors on the fly and prevents networking and storage equipment from crashing.

Online Piracy Can Boost Comic Book Sales, Research Finds (torrentfreak.com) 33

A number of studies show that piracy helps movies, TV shows, and music albums find a much wider audience, which in turn, often times, help in boosting their revenue. But what about comic books? A new academic study shows that piracy can have a positive effect on comic book sales, too, albeit under certain conditions. From a report on TorrentFreak: Manga, in particular, has traditionally been very popular on file-sharing networks and sites. These are dozens of large sites dedicated to the comics, which are downloaded in their millions. According to the anti-piracy group CODA, which represents Japanese comic publishers, piracy losses overseas are estimated to be double the size of overseas legal revenue. With this in mind, Professor Tatsuo Tanaka of the Faculty of Economics at Keio University decided to look more closely at how piracy interacts with legal sales. In a natural experiment, he examined how the availability of pirated comic books affected revenue. Interestingly, the results show that decreased availability of pirated comics doesn't always help sales. In fact, for comics that no longer release new volumes, the effect is reversed. "Piracy decreases sales of ongoing comics, but it increases sales of completed comics," Professor Tanaka writes. "To put this another way, displacement effect is dominant for ongoing comics, and advertisement effect is dominant for completed comics," he adds.

Netflix Just Announced a User Focused Security Application (netflix.com) 40

Moving beyond movies and TV shows (and their DVDs), Netflix announced on Tuesday Stethoscope, its "first project following a User Focused Security approach." From a company's blog post: The notion of "User Focused Security" acknowledges that attacks against corporate users (e.g., phishing, malware) are the primary mechanism leading to security incidents and data breaches, and it's one of the core principles driving our approach to corporate information security. [...] Stethoscope is a web application that collects information for a given user's devices and gives them clear and specific recommendations for securing their systems. If we provide employees with focused, actionable information and low-friction tools, we believe they can get their devices into a more secure state without heavy-handed policy enforcement. The company says Stethoscope tracks disk encryption, firewall, automatic updates, up-to-date OS/software, screen lock, jailbroken/rooted status, security software stack configurations of the device.
