You Could Soon Be Manufacturing Your Own Drugs -- Thanks To 3D Printing (sciencemag.org) 20

sciencehabit shares a report from Science Magazine: Forget those long lines at the pharmacy: Someday soon, you might be making your own medicines at home. That's because researchers have tailored a 3D printer to synthesize pharmaceuticals and other chemicals from simple, widely available starting compounds fed into a series of water bottle -- size reactors. The work, they say, could digitize chemistry, allowing users to synthesize almost any compound anywhere in the world.

In today's issue of Science, Leroy Cronin, a chemist at the University of Glasgow in the United Kingdom, and his colleagues report printing a series of interconnected reaction vessels that carry out four different chemical reactions involving 12 separate steps, from filtering to evaporating different solutions. By adding different reagents and solvents at the right times and in a precise order, they were able to convert simple, widely available starting compounds into a muscle relaxant called baclofen. And by designing reactionware to carry out different chemical reactions with different reagents, they produced other medicines, including an anticonvulsant and a drug to fight ulcers and acid reflux. So why not just buy a reactionware kit and scrap the printing? "This approach will allow the on-demand production of chemicals and drugs that are in short supply, hard to make at big facilities, and allow customization to tailor them to the application," Cronin says.

US Tests Nuclear Power System To Sustain Astronauts On Mars (reuters.com) 37

Initial tests in Nevada on a compact nuclear power system designed to sustain a long-duration NASA human mission on the inhospitable surface on Mars have been successful and a full-power run is scheduled for March, officials said on Thursday. Reuters reports: National Aeronautics and Space Administration and U.S. Department of Energy officials, at a Las Vegas news conference, detailed the development of the nuclear fission system under NASA's Kilopower project. Months-long testing began in November at the energy department's Nevada National Security Site, with an eye toward providing energy for future astronaut and robotic missions in space and on the surface of Mars, the moon or other solar system destinations. A key hurdle for any long-term colony on the surface of a planet or moon, as opposed to NASA's six short lunar surface visits from 1969 to 1972, is possessing a power source strong enough to sustain a base but small and light enough to allow for transport through space. NASA's prototype power system uses a uranium-235 reactor core roughly the size of a paper towel roll. The technology could power habitats and life-support systems, enable astronauts to mine resources, recharge rovers and run processing equipment to transform resources such as ice on the planet into oxygen, water and fuel. It could also potentially augment electrically powered spacecraft propulsion systems on missions to the outer planets.

Why People Dislike Really Smart Leaders (scientificamerican.com) 248

An anonymous reader quotes a report from Scientific American: Intelligence makes for better leaders -- from undergraduates to executives to presidents -- according to multiple studies. It certainly makes sense that handling a market shift or legislative logjam requires cognitive oomph. But new research on leadership suggests that, at a certain point, having a higher IQ stops helping and starts hurting. The researchers looked at 379 male and female business leaders in 30 countries, across fields that included banking, retail and technology. The managers took IQ tests (an imperfect but robust predictor of performance in many areas), and each was rated on leadership style and effectiveness by an average of eight co-workers. IQ positively correlated with ratings of leader effectiveness, strategy formation, vision and several other characteristics -- up to a point. The ratings peaked at an IQ of around 120, which is higher than roughly 80 percent of office workers. Beyond that, the ratings declined. The researchers suggest the "ideal" IQ could be higher or lower in various fields, depending on whether technical versus social skills are more valued in a given work culture. The study's lead author, John Antonakis, a psychologist at the University of Lausanne in Switzerland, suggests leaders should use their intelligence to generate creative metaphors that will persuade and inspire others -- the way former U.S. President Barack Obama did. "I think the only way a smart person can signal their intelligence appropriately and still connect with the people," Antonakis says, "is to speak in charismatic ways."

Tesla Is Last In the Driverless Vehicle Race, Report Says (usnews.com) 107

Navigant Research has compiled a new report on 19 companies working on automated driving systems, and surprisingly, Tesla came in last place. U.S. News & World Report: Navigant ranked the 19 major companies developing AV technology based on 10 criteria, including vision, market strategy, partnerships, production strategy, technology, product quality and staying power. According to the report, General Motors Co. and Waymo, the auto unit of Alphabet, are the top two AV investment opportunities in the market today. Tesla and Apple are the two biggest laggards in the AV race, according to Navigant's rankings.

Investors are acutely aware of Tesla's production and distribution disadvantages compared to legacy automakers like GM, but Navigant is also highly critical of Tesla's technology. "The autopilot system on current products has stagnated and, in many respects, regressed since it was first launched in late 2015," Navigant says in the report, according to Ars Technica. "More than one year after launching V2, Autopilot still lacks some of the functionality of the original, and there are many anecdotal reports from owners of unpredictable behavior."

Lifesaving Drone Makes First Rescue In Australia (yahoo.com) 35

Zorro shares a report from Yahoo News: A pair of Australian swimmers on Thursday became the first people to be rescued in the ocean by a drone when the aerial lifesaver dropped a safety device to distressed teens caught in rough seas. In what is believed to be a world-first drone surf rescue, two boys on Thursday got caught in three-meter (10-foot) swells while swimming off Lennox Head in New South Wales, near the border with Queensland. Beachgoers onshore raised the alarm to the lifeguards who then alerted the drone pilot, and the aerial lifesaver was deployed in moments.

Along with their ability to spot swimmers in trouble and deliver life saving devices faster than traditional lifesaving techniques, like launching surfboards or rubber dinghies, drones are being used in Australia to spot underwater predators like sharks and jellyfish. Artificial intelligence is being developed using thousands of images captured by a drone camera to build an algorithm that can identify different ocean objects. The software can differentiate between sea creatures, like sharks which it can recognize with more than 90 percent accuracy, compared to about 16 percent with the naked eye.

Amazon Picks 20 Finalists For 'HQ2' Second Headquarters Location (nbcnews.com) 115

bigpat writes: Amazon took in hundreds of proposals and narrowed it down to twenty places for its "second" headquarters, with up to 50,000 new jobs promised in the next 15 years and millions of square feet of office and research space. The cities include: Atlanta, Austin, Boston, Chicago, Columbus, Dallas, Denver, Indianapolis, Los Angeles, Miami, Montgomery County, Maryland, Nashville, Newark, NJ, New York City, Northern Virginia, Philadelphia, Pittsburgh, Raleigh, Toronto and Washington D.C. Amazon said that it will now work with the candidate locations to examine their proposals more closely and request additional information to "evaluate the feasibility of a future partnership that can accommodate our hiring plans as well as benefit our employees and the local community." The company said it would make its decision later in 2018.

Google's Fuchsia OS On the Pixelbook (arstechnica.com) 46

An anonymous reader quotes a report from 9to5Google: Our early look at Fuchsia OS last May provided a glimpse into a number of new interface paradigms. Several months later, we now have an updated hands-on with Google's future operating system that can span various form factors. This look at the in-development OS eight months later comes courtesy of Ars Technica who managed to get Fuchsia installed on the Pixelbook. The Made by Google Chromebook is only the third officially supported "target device" for Fuchsia development. As our last dive into the non-Linux kernel OS was through an Android APK, we did not encounter a lockscreen. The Ars hands-on shows a basic one that displays the time at center and Fuchsia logo in the top-left corner to switch between phone and desktop/tablet mode, while a FAB (of sorts) in the opposite corner lets users bring up WiFi controls, Login, and Guest.

Only Guest is fully functioning at this stage -- at least for non-Google employees. Once in this mode, we encounter an interface similar to the one we spotted last year. The big difference is how Google has filled in demo information and tweaked some elements. On phones and tablets, Fuchsia essentially has three zones. Recent apps are above, at center are controls, and below is a mixture of the Google Feed and Search. The controls swap out the always-displayed profile icon for a Fuchsia button. Tapping still surfaces Quick Settings which actually reflect current device battery levels and IP address. Impressively, Ars found a working web browser that can actually surf the internet. Google.com is the default homepage, with users able to visit other sites through that search bar. Other examples of applications, which are just static images, include a (non-working) phone dialer, video player, and Google Docs. The Google Calendar is notable for having subtle differences to any known version, including the tablet or web app.

Ask Slashdot: How Would You Explain Einstein's Theories To a Nine-Year-Old? 202

SiggyRadiation writes: A few days ago, my 9-year-old son asked me why Albert Einstein was so famous. I decided not just to start with the famous formula E=mc^2, because that just seemed to be the easy way out. So I tried to explain what mass and energy are. Then I asked him to try to explain gravity to me. The earth pulls at you because it has a lot of mass. But how can the earth influence your body, pull your feet to the ground, without actually touching you? Why is it that one thing (the earth) can influence something else (you) without actually being connected? Isn't that weird? Einstein figured out how energy, mass and gravity work and are related to each other. This is where our conversation ended.

Afterwards I thought: this might be a nice question to ask on Slashdot; how would I continue this discussion to explain it to him further? Of course, with the goal of further feeding his interest in physics.

'Text Bomb' Is Latest Apple Bug (bbc.com) 49

An anonymous reader quotes a report from the BBC: A new "text bomb" affecting Apple's iPhone and Mac computers has been discovered. Abraham Masri, a software developer, tweeted about the flaw which typically causes an iPhone to crash and in some cases restart. Simply sending a message containing a link which pointed to Mr Masri's code on programming site GitHub would be enough to activate the bug -- even if the recipient did not click the link itself. Mr Masri said he "always reports bugs" before releasing them. Apple has not yet commented on the issue. On a Mac, the bug reportedly makes the Safari browser crash, and causes other slowdowns. Security expert Graham Cluley wrote on his blog that the bug does not present anything to be particularly worried about -- it's merely very annoying. After the link did the rounds on social media, Mr Masri removed the code from GitHub, therefore disabling the "attack" unless someone was to replicate the code elsewhere.

Bitcoin's Fluctuations Are Too Much For Even Ransomware Cybercriminals (theguardian.com) 60

Bitcoin's price swings are so huge that even ransomware developers are dialling back their reliance on the currency, according to researchers at cybersecurity firm Proofpoint. From a report: Over the last quarter of 2017, researchers saw a fall of 73% in payment demands denominated in bitcoin. When demanding money to unlock a victim's data, cybercriminals are now more likely to simply ask for a figure in US dollars, or a local currency, than specify a sum of bitcoin. Just like conventional salespeople, ransomware developers pay careful attention to the prices they charge. Some criminals offer discounts depending on the region the victim is in, offering cheaper unlocking to residents of developing nations, while others use an escalating price to encourage users to pay quickly and without overthinking things. But a rapidly oscillating bitcoin price plays havoc with those goals, Proofpoint says.

Microsoft Resumes Meltdown and Spectre Updates for AMD Devices (bleepingcomputer.com) 38

Microsoft has resumed the rollout of security updates for AMD devices. The updates patch the Meltdown and Spectre vulnerabilities. From a report: Microsoft released these patches on January 3, but the company stopped the rollout for AMD-based computers on January 9 after users reported crashes that plunged PCs into unbootable states. After working on smoothing out the problems with AMD, Microsoft announced today it would resume the rollout of five (out of nine) security updates.

Global Warming Predictions May Now Be a Lot Less Uncertain (wired.com) 257

An anonymous reader shares a report: Humanity must not pass a rise of 2 degrees Celsius in global temperature from pre-industrial levels, so says the Paris climate agreement. Cross that line and the global effects of climate change start looking less like a grave situation and more like a catastrophe. The frustrating bit about studying climate change is the inherent uncertainty of it all. Predicting where it's going is a matter of mashing up thousands of variables in massive, confounding systems. But today in the journal Nature, researchers claim they've reduced the uncertainty in a key metric of climate change by 60 percent, narrowing a range of potential warming from 3C to 1.2C. And that could have implications for how the international community arrives at climate goals like it did in Paris. The metric is called equilibrium climate sensitivity, but don't let the name scare you.

Less Than 1 in 10 Gmail Users Enable Two-Factor Authentication (theregister.co.uk) 218

It has been nearly seven years since Google introduced two-factor authentication for Gmail accounts, but virtually no one is using it. From a report: In a presentation at Usenix's Enigma 2018 security conference in California, Google software engineer Grzegorz Milka this week revealed that, right now, less than 10 per cent of active Google accounts use two-step authentication to lock down their services. He also said only about 12 per cent of Americans have a password manager to protect their accounts, according to a 2016 Pew study.

Senate Passes Bill Renewing NSA's Internet Surveillance Program (reuters.com) 85

From a report: The U.S. Senate on Thursday passed a bill to renew the National Security Agency's warrantless internet surveillance program for six years and with minimal changes, overcoming objections from civil liberties advocates that it did too little to safeguard the privacy of Americans. From a report on CNET: The programs, known as Prism and Upstream, allow the NSA to collect online communications of foreigners outside the US. Prism collects these communications from internet services, and Upstream taps into the internet's infrastructure to capture information in transit. Some communications from Americans and others in the US are collected in the process. The vote Thursday renews the programs for six years. The House approved a bill renewing the programs last week. Former NSA contractor Edward Snowden first revealed the programs by leaking information about them to journalists in 2013. After the news coverage, the administration of President Barack Obama declassified much information about the programs.
