Jess Shankleman reports via Bloomberg: Solar power, once so costly it only made economic sense in spaceships, is becoming cheap enough that it will push coal and even natural-gas plants out of business faster than previously forecast. That's the conclusion of a Bloomberg New Energy Finance outlook for how fuel and electricity markets will evolve by 2040. The research group estimated solar already rivals the cost of new coal power plants in Germany and the U.S. and by 2021 will do so in quick-growing markets such as China and India. The scenario suggests green energy is taking root more quickly than most experts anticipate. It would mean that global carbon dioxide pollution from fossil fuels may decline after 2026, a contrast with the International Energy Agency's central forecast, which sees emissions rising steadily for decades to come. The report also found that through 2040:
-China and India represent the biggest markets for new power generation, drawing $4 trillion, or about 39 percent all investment in the industry.
-The cost of offshore wind farms, until recently the most expensive mainstream renewable technology, will slide 71 percent, making turbines based at sea another competitive form of generation.
-At least $239 billion will be invested in lithium-ion batteries, making energy storage devices a practical way to keep homes and power grids supplied efficiently and spreading the use of electric cars.
-Natural gas will reap $804 billion, bringing 16 percent more generation capacity and making the fuel central to balancing a grid that's increasingly dependent on power flowing from intermittent sources, like wind and solar.Read Replies (0)

When the Samsung Galaxy S8 and S8+ went on sale in the North American market, it was missing one of its most touted features -- the Bixby smart assistant. Technically, it was available on launch day but its voice functionality was missing due to issues with the English language version, thus rendering the dedicated Bixby button on the side of the S8 and S8+ nearly useless. Today, Bixby Voice is finally making its stateside debut -- but only as a preview. TechCrunch reports: The company is positioning this is a "sneak peak" for the feature that was initially planned to debut on its new flagship phones. Starting this week, a select number of Galaxy S8 and S8+ can sign up to be among the first in the U.S. to test it out. From the sound of it, Samsung's still working on some tweaks here, using this limited launch to basically do some public beta testing. The company didn't have a lot to say about the closed launch, aside from reiterating some of its grandiose plans for making Bixby, "an integral part of our connected ecosystem," according to the company's CTO.Read Replies (0)

Elon Musk has put his Mars-colonization vision to paper, and you can read it for free. SpaceX's billionaire founder and CEO published the plan, which he unveiled at a conference in Mexico in September 2016, in the journal New Space. From a report: The paper outlines early designs of the gigantic spacecraft, designed to carry 100 passengers, that he hopes to construct. "The thrust level is enormous," the paper states. "We are talking about a lift-off thrust of 13,000 tons, so it will be quite tectonic when it takes off." Creating a fully self-sustained civilisation of around one million people -- the ultimate goal -- would take 40-100 years according to the plans. Before full colonisation takes place, though, Musk needs to entice the first pioneers to pave the way.Read Replies (0)

Research firm Sensor Tower shares an analysis: As the minimum storage capacity of iPhone continues to increase -- it sits at 32 GB today on the iPhone 7, double the the iPhone 5S's 16 GB circa 2013 -- it's not surprising that the size of apps themselves is getting larger. In fact, Apple raised the app size cap from 2 GB to 4 GB in early 2015. What's surprising is how much faster they're increasing in size compared to device storage itself. According to Sensor Tower's analysis of App Intelligence, the total space required by the top 10 most installed U.S. iPhone apps has grown from 164 MB in May 2013 to about 1.8 GB last month, an 11x or approximately 1,000 percent increase in just four years. [...] Of the top 10 most popular U.S. iPhone apps, the minimum growth we saw in app size since May 2013 was 6x for both Spotify and Facebook's Messenger. As the chart above shows, other apps, especially Snapchat, have grown considerably more. In fact, Snapchat is more than 50 times larger than it was four years ago, clocking in at 203 MB versus just 4 MB at the start of the period we looked at. It's not the largest app among the top 10, however. That distinction goes to Facebook, which, at 388 MB, is 12 times larger than it was in May 2013 when it occupied 32 MB. It grew by about 100 MB in one update during September of last year.Read Replies (0)

An anonymous reader shares excerpts from a Scientific American article: In recent years, increasingly detailed experimental procedures have lead to a huge influx in the biological data available to scientists. This data is being used to generate hypotheses about the complexity of previously abstruse biological systems. In order to test these hypotheses, they must be written down in the form of a model which can be interrogated to determine whether it correctly mimics the biological observations. Mathematics is the natural language in which to do this. In addition, the advent of, and subsequent increase in, computational ability over the last 60 years has enabled us to suggest and then interrogate complex mathematical models of biological systems. The realisation that biological systems can be treated mathematically, coupled with the computational ability to build and investigate detailed biological models, has led to the dramatic increase in the popularity of mathematical biology. Maths has become a vital weapon in the scientific armoury we have to tackle some of the most pressing questions in medical, biological and ecological science in the 21st century. By describing biological systems mathematically and then using the resulting models, we can gain insights that are impossible to access though experiments and verbal reasoning alone. Mathematical biology is incredibly important if we want to change biology from a descriptive into a predictive science -- giving us power, for example, to avert pandemics or to alter the effects of debilitating diseases.Read Replies (0)

An anonymous reader quotes a report from The Verge: Amazon's long been a go-to for people to online price compare while shopping at brick-and-mortars. Now, a new patent granted to the company could prevent people from doing just that inside Amazon's own stores. The patent, titled "Physical Store Online Shopping Control," details a mechanism where a retailer can intercept network requests like URLs and search terms that happen on its in-store Wi-Fi, then act upon them in various ways. The document details in great length how a retailer like Amazon would use this information to its benefit. If, for example, the retailer sees you're trying to access a competitor's website to price check an item, it could compare the requested content to what's offered in-store and then send price comparison information or a coupon to your browser instead. Or it could suggest a complementary item, or even block content outright. Amazon's patent also lets the retailer know your physical whereabouts, saying, "the location may be triangulated utilizing information received from a multitude of wireless access points." The retailer can then use this information to try and upsell you on items in your immediate area or direct a sales representative to your location.Read Replies (0)

dryriver shares a report from the BBC: Celebrated inventor and physicist Nikola Tesla swore by toe exercises -- every night, he'd repeatedly "squish" his toes, 100 times for each foot, according to the author Marc J Seifer. While it's not entirely clear exactly what that exercise involved, Tesla claimed it helped to stimulate his brain cells. The most prolific mathematician of the 20th Century, Paul Erdos, preferred a different kind of stimulant: amphetamine, which he used to fuel 20-hour number benders. When a friend bet him $500 that he couldn't stop for a month, he won but complained "You've set mathematics back a month." Newton, meanwhile, bragged about the benefits of celibacy. When he died in 1727, he had transformed our understanding of the natural world forever and left behind 10 million words of notes; he was also, by all accounts, still a virgin (Tesla was also celibate, though he later claimed he fell in love with a pigeon). It's common knowledge that sleep is good for your brain -- and Einstein took this advice more seriously than most. He reportedly slept for at least 10 hours per day -- nearly one and a half times as much as the average American today (6.8 hours). But can you really slumber your way to a sharper mind? Many of the world's most brilliant scientific minds were also fantastically weird. From Pythagoras' outright ban on beans to Benjamin Franklin's naked "air baths," the path to greatness is paved with some truly peculiar habits.Read Replies (0)
