Submission + - Intel Blunts ARM Assault With Expanded Xeon D (nextplatform.com)

An anonymous reader writes: In years gone by, blunting the ARM assault was a task that the server-class Atom processors were given, but as ARM server chips have gotten beefier, Intel has changed tactics with a single-socket Xeon chip that is geared down, in terms of its price and performance, and implemented in a system on chip packaging like many of the ARM chips and unlike the Xeon E3. (Well, technically speaking, the Xeon D is a system on package, since the southbridge chipset that provides support for legacy I/O devices is not etched onto the die but rather hooked to the Xeon D processor and then integrated in the same chip package.) This is not just a matter of semantics, but the point is that the Xeon D has more oomph than the Atom C series. But practically speaking, Intel is providing the kind of integrated functionality that hyperscalers as well as makers of storage and networking devices – and, by the way, many hyperscalers make their own storage and networking devices and will be keen on cheap, low-power,

Submission + - uBeam's Problems with Efficiency, Practicality and Cost Makes Experts Skeptical (labusinessjournal.com)

An anonymous reader writes: Some question if uBeam's wireless charging system is just hot air.

From article:

“It seems like an ungodly inefficient way to transmit energy,” said Leonard Bond, a physicist and professor of aerospace engineering at Iowa State University, who noted nothing could be deemed impossible until uBeam showed a working cellphone prototype, which it has not done. “Maybe these guys get an amazing award for having done something, but I’m not convinced yet.”

Basically, physicists, electrical engineers, mechanical engineers and ultrasonic researchers say it's rudimentarily possible- and not novel- but probably not nearly as efficient, practical or cost effective as uBeam claims.

Submission + - Muzzled Canadian scientists can now speak freely with public (thestar.com)

Layzej writes: Over the last 10 years, policies were put in place to prevent Canadian scientists from freely discussing taxpayer-funded science with the public. "media relations contacts" were enlisted to monitor and record interactions with the press. Interviews and often the questions to be asked were vetted ahead of time, and responses given by scientists frequently monitored or prohibited. The journal Nature, one of the world’s top science journals, called the policy a “Byzantine approach to the press, prioritizing message control and showing little understanding of the importance of the free flow of scientific knowledge.”

The new government in Canada is lifting these restrictions. Scientists at the Department of Fisheries and Oceans were told Thursday they can now speak to the media. In a statement on Friday afternoon, Navdeep Bains, Canada's new minister of innovation, science and economic development said "Our government values science and will treat scientists with respect. This is why government scientists and experts will be able to speak freely about their work to the media and the public,"

Submission + - Google Tests Automated Email Responses (blogspot.com)

An anonymous reader writes: Google's research blog today announced a new feature for for their Inbox email app: a neural network that composes short responses to emails you receive. For example, if somebody emails you an invitation to an event, the app will detect that by scanning the words in the message and present you with three options for a quick response. "A naive attempt to build a response generation system might depend on hand-crafted rules for common reply scenarios. But in practice, any engineer’s ability to invent “rules” would be quickly outstripped by the tremendous diversity with which real people communicate. A machine-learned system, by contrast, implicitly captures diverse situations, writing styles, and tones. These systems generalize better, and handle completely new inputs more gracefully than brittle, rule-based systems ever could." Of course, you can skip them entirely, or use them and add your own words as well. How long until our email systems do most of our talking for us?

Submission + - MIT Drone Autonomously Avoids Obstacles at 30 MPH (roboticstrends.com)

An anonymous reader writes: Traditional obstacle-avoidance software uses images from each camera, and search through the depth-field at multiple distances to determine if an object is in the drone’s path. Such approaches are computationally intensive, meaning the drone can’t fly faster than 6 miles per hour without specialized processors.

Barry’s realization was that, at the fast speeds that his drone could travel, the world simply does not change much between frames. Because of that, he could get away with computing just a small subset of measurements — distances of 10 meters away.

“As you fly, you push that 10-meter horizon forward, and, as long as your first 10 meters are clear, you can build a full map of the world around you,” Barry says.

Submission + - Tyrannosaurs were probably cannibals (sciencemag.org)

sciencehabit writes: For years, paleontologists have wondered: Did the fierce Tyrannosaurus rex eat its own? A 66-million-year-old fossil unearthed in eastern Wyoming provides some of the strongest evidence yet that it did, researchers say. The fossil—a tyrannosaur leg bone fragment the size of a human forearm—is scarred with deep grooves left by a large meat-eater as it tore flesh from the ancient carcass. One of the grooves is particularly telling because it contains tiny channels left by tooth serrations called denticles. Those channels rule out smooth-toothed predators like crocodiles, instead pointing to bipedal meat-eating dinosaurs called theropods. And since the only large theropods known to be living then in the region—T. rex and Nanotyrannus lancensis—both belong to the tyrannosaur subgroup, the evidence bolsters the idea that tyrannosaurs were, in some cases, cannibals.

Submission + - FDA approves drug that uses herpes virus to fight cancer (nature.com)

An anonymous reader writes: U.S. regulators have approved a first-of-a-kind drug that uses the herpes virus to infiltrate and destroy melanoma. Nature reports: "With dozens of ongoing clinical trials of similar ‘oncolytic’ viruses, researchers hope that the approval will generate the enthusiasm and cash needed to spur further development of the approach. 'The era of the oncolytic virus is probably here,' says Stephen Russell, a cancer researcher and haematologist at the Mayo Clinic in Rochester, Minnesota. 'I expect to see a great deal happening over the next few years.' Many viruses preferentially infect cancer cells. Malignancy can suppress normal antiviral responses, and sometimes the mutations that drive tumour growth also make cells more susceptible to infection. Viral infection can thus ravage a tumour while leaving abutting healthy cells untouched, says Brad Thompson, president of the pharmaceutical-development firm Oncolytics Biotech in Calgary, Canada."

Submission + - Container provisioning with Guix

paroneayea writes: Container provisioning just landed in GNU Guix, the purely functional, scheme-based, totally free software package manager (and with GuixSD, distro too). Containers now work with both the "guix system" command as a lightweight and isolated substitution for VMs to launch applications and test reproducible deployments with, and a "guix environment" command for launching isolated development environments. Since the word "container" has been mentioned, some will no doubt be wondering how this compares to Docker, and fortunately such a breakdown has been given on a mailing list post.

Submission + - Study: More Than Two-Thirds of Patients on Anti-Depressants Not Depressed (breitbart.com)

schwit1 writes: A new study shows that more than two-thirds — some 69 percent – of patients using anti-depressants do not actually meet the criteria for depressive disorder.

The study, which appears in the Journal of Clinical Psychiatry , finds that many individuals who are prescribed and take antidepressant medications may not actually have a depressive disorder, and that such drugs are often used by patients who do not meet the diagnostic criteria of depression.

According to the research, among the users of antidepressant medications, 69 percent never met the diagnostic criteria for major depressive disorder (MDD), and 38 percent also never met those for obsessive-compulsive disorder, panic disorder, social phobia, or generalized anxiety disorder – for which the antidepressant medications are sometimes prescribed.

Submission + - Arthritis drug doubles as hair-fertilizer (sciencemag.org)

sciencehabit writes: A class of drugs already approved by the U.S. Food and Drug Administration for treating rheumatoid arthritis is raising hairs in the research community—literally. Previous studies had shown that Janus kinase inhibitors, including tofacitinib and ruxolitinib, can treat alopecia areata, an autoimmune disease that causes bald patches when immune cells attack hair follicles. The researchers noticed that, when applied topically, the treatment seemed to be directly spurring robust hair growth. New research suggests that the drugs can do the same even in mice without the autoimmune disease. When researchers applied the drugs topically to the right side of mice whose hair follicles were in a resting phase, the difference was clear: 90% of the treated mice had hair growth within 10 days. The drugs, it turned out, had kick-started their hair cycles, putting follicles into an active growth phase. Results were similar when the scientists grafted healthy human scalp skin onto mice.

Submission + - SPAM: Clock Movements That Wait Not For Time Or Tide

hightorquemovements writes: Clock motions are in a feeling the central processing units of all watches. Clockmakers start with clock movements (or clock motors, as they are also called) in establishing the attributes of their style. All other clock components (mostly dials as well as hands, yet additionally alarms, chimes, uniqueness pendulums, and so on) are second considerations.

Clock activities have to be very accurate. When one checks the time nowadays, he or she expects the information received to be in conformity with a viewed global criterion. Although this expectation could be unreasonable, couple of people endure more than a handful of seconds drift, either quick or slow down, over the course of, say, a month or maybe a week.

So, equally as time and tide await no man, the activity had better maintain as well. As well as this is true no matter exactly what it is tracking.

Simply puts, some motors track the time, cycling every 12 hrs (the most common clock). Others pattern every 24 Hr, and also still others could in addition track the day of the week or the date of the month. There are likewise movements that track weather condition sensations, including temperature and also tide level.

The methods clocks utilize to keep trusted time have actually advanced over the years. Generally a weight or coiled springtime used a force that created a pendulum to swing. The back-and-forth activity would certainly in turn revolve a gear a small amount.

The unregulated rate of gear turning would differ depending upon the force applied at any given moment. Nonetheless, an escapement mechanism offered regulation. It was adjusted such that the gear would transform exactly the very same amount every second.

In the electronic age, pendulums and also escapements have paved the way to the quartz crystal. This tool sends out resonances extremely rapidly at a regularity that does not fluctuate. Digital accumulators and also counting registers subdivide the regularity to a 1-second rate.

Both approaches have systems for incrementing minutes after One Minute as well as hours after 60 minutes. In the traditional instance this was accomplished using a gear network. The modern method makes use of electronic triggering.

The conventional approach has actually largely lapsed, though modern clocks are in some cases designed to replicate the old appearances. For instance, a grandfather clock will certainly reveal a turning pendulum although it is purely aesthetic as well as has no bearing on the actual operation of the clock motion.

Motions that display weather condition info are rather various monsters. Whereas temporal data are (or can be) self-generated, climate information to be shown need to be partially or entirely obtained from exterior sources.

Determining temperature level is relatively simple. There are lots of popular ways to do this based on the growth and tightening of some product connected to the warming and cooling of the air.

Typical thermostats typically utilize the instant size of the sensing unit itself to display the temperature. Weather condition motions need to transform the sensor appreciate right into an angle differential to ensure that a hand will certainly direct at the appropriate number on a dial.

Showing tide level is a lot more complex, as there are a number of factors involved. The position of the moon is the primary element, yet the moon's loved one placement to the sun is a secondary one. Additionally, the time lag between moon position as well as high or low tide is not global however varies according to geographical location.

Until now we have actually been discussing the temporal actions of the trend, however there are also variations in just how commonly it turns. Local problems greatly affect this depending upon the level of vibration they have with tidal patterns. Places like the Bay of Fundy are very resonant, generating upright changes in trend degree in the 10s of meters two times daily.

The outcome is that display of tide degree requires some quantity of calibration. The temporal habits can be self-generated, though preliminary problems have to be established, comparable to resetting a clock. Yet the movement has to allow input from the individual pertaining to time lag and trend level extremes dued to regional conditions.

Though the temporal and also weather condition habits we have actually been talking about are rather various, it is feasible to locate motions that supply both attributes in a single unit. The vital aspect is precision. It is very important to discover clock motions that neither prepare for neither await time or tide.
