Cholesterol-lowering drugs may fight infectious disease

Science Daily - Mon, 21/08/2017 - 7:10pm
Scientists found a gene variant that affects cholesterol levels also could increase the risk of contracting typhoid fever. A common cholesterol-lowering drug could protect animal models against Salmonella Typhi, the culprit behind the potentially deadly infection. The findings give insight into the mechanisms that govern human susceptibility to infectious disease and point to possible avenues to protect against pathogens -- like Salmonella or Ebola -- whose entry into host cells is regulated by cholesterol.

Cord-Cutting Still Doesn't Beat the Cable Bundle

Slashdot - Mon, 21/08/2017 - 6:40pm
I'd like to cut the cord, writes Brian Barrett for Wired, then, the very instant I allow myself to picture what life looks like after that figurative snip, my reverie comes crashing down. From an article: Cutting the cord is absolutely right for some people. Lots of people, maybe. But it's not that cheap, and it's not that easy, and there's not much hope of improvement on either front any time soon. Not to turn this into a math experiment, but let's consider cost. Assuming you're looking for a cord replacement, not abandoning live television altogether, you're going to need a service that bundles together a handful of channels and blips them to your house over the internet. The cheapest way you can accomplish this is to pay Sling TV $20 per month, for which you get 29 channels. That sounds not so bad, and certainly less than your cable bill. But! Sling Orange limits you to a single stream. If you're in a household with others, you'll probably want Sling Blue, which offers multiple streams and 43 channels for $25 per month. But! Sling Orange and Sling Blue have different channel lineups (ESPN is on Orange, not Blue, while Orange lacks FX, Bravo and any locals). For full coverage, you can subscribe to both for $40. But! Have kids? You'll want the Kids Extra package for another $5 per month. Love ESPNU? Grab that $5 per month sports package. HBO? $15 per month, please. Presto, you're up to $65 per month. But! Don't forget the extra $5 for a cloud-based DVR. Plus the high-speed internet service that you need to keep your stream from buffering, which, by the way, it'll do anyway. That's not to pick on Sling TV, specifically. But paying $70 to quit cable feels like smoking a pack of Parliaments to quit Marlboro Lights. You run into similar situations across the board, whether it's a higher base rate, or a limited premium selection, or the absence of local programming altogether. It turns out, oddly enough, that things cost money, whether you access those things through traditional cable packages or through a modem provided to you by a traditional cable operator.

Driverless Cars Need a Lot More Than Software, Ford CTO Says

Slashdot - Mon, 21/08/2017 - 6:00pm
In an interview, Ken Washington, Ford's Chief Technical Officer, shared company's views on how autonomy will change car design. From an article: The biggest influence will be how the cars are bought, sold and used: "You would design those vehicles differently depending on what business model (is being used). We're working through that business model question right now," he said. The biggest misconceptions about autonomous capabilities is that it's only about software: "People are imagining that the act of doing software for autonomy is all you need to do and then you can just bolt it to the car," he said. "I don't think it's possible to describe what an autonomous vehicle is going to look like," he added.

Supreme Court Asked To Nullify the Google Trademark

Slashdot - Mon, 21/08/2017 - 5:20pm
Is the term "google" too generic and therefore unworthy of its trademark protection? That's the question before the US Supreme Court. From a report: What's before the Supreme Court is a trademark lawsuit that Google already defeated in a lower court. The lawsuit claims that Google should no longer be trademarked because the word "google" is synonymous to the public with the term "search the Internet." "There is no single word other than google that conveys the action of searching the Internet using any search engine," according to the petition to the Supreme Court. It's perhaps one of the most consequential trademark case before the justices since they ruled in June that offensive trademarks must be allowed. The Google trademark dispute dates to 2012 when a man named Chris Gillespie registered 763 domain names that combined "google" with other words and phrase, including "googledonaldtrump.com."

Intel Launches 8th Generation Core CPUs

Slashdot - Mon, 21/08/2017 - 4:40pm
Reader joshtops writes: Today Intel is launching its new 8th Generation family of processors, starting with four CPUs for the 15W mobile family. There are two elements that make the launch of these 8th Gen processors different. First is that the 8th Gen is at a high enough level, running basically the same microarchitecture as the 7th Gen. But the key element is that, at the same price and power where a user would get a dual core i5-U or i7-U in their laptop, Intel will now be bumping those product lines up to quad-cores with hyperthreading. This gives a 100% gain in cores and 100% gain in threads. Obviously nothing is for free, so despite Intel stating that they've made minor tweaks to the microarchitecture and manufacturing to get better performing silicon, the base frequencies are down slightly. Turbo modes are still high, ensuring a similar user experience in most computing tasks. Memory support is similar -- DDR4 and LPDDR3 are supported, but not LPDDR4 -- although DDR4 moves up to DDR4-2400 from DDR4-2133. Another change from 7th Gen to 8th Gen will be in the graphics. Intel is upgrading the nomenclature of the integrated graphics from HD 620 to UHD 620, indicating that the silicon is suited for 4K playback and processing.

Antarctic salt-loving microbes provide insights into evolution of viruses

Science Daily - Mon, 21/08/2017 - 4:28pm
Scientists studying microbes from some of the saltiest lakes in Antarctica have discovered a new way the microbes can share DNA that could help them grow and survive. The research, based on 18 months of water sampling in remote Antarctic locations, could throw light on the evolutionary history of viruses. The team discovered some of the microbes contained small molecules of DNA called plasmids.
