dryriver writes: In the past, Neanderthal humans were believed to be largely close-distance hunters. A new paper in the journal Nature, based on actual outdoor tests with multiple test subjects throwing two wooden spears closely mimicking ancient spears found in various places at a target, surmises that spear throwing Neanderthals may in fact have been able to kill animals at distances of 60 feet or even greater. The authors found that targeting a wooden spear accurately at that distance takes skill, and even worked out the impact velocity of Neanderthal spears at such a distance. Nevertheless, Neanderthals with sufficient practice in spear throwing may very well have been capable of killing at distances far greater than previously thought. This changes the assumption that Neanderthals needed to get very close to animals in order to have a chance of killing them.

In a press release, Samsung said that it will be replacing plastic packaging with "environmentally sustainable elements" beginning this year. The Verge reports: The company announced today that it will replace the plastic used in phones, tablets and wearables for molds and accessory bags made with "eco-friendly materials." The company also says that it will also change the design for its phone chargers to reduce the use of plastics, "swapping the glossy exterior with a matte finish." The company will also replace plastic bags used to protect its air conditioners, refrigerators, TVs, and washing machines with recycled materials and bioplastics that come from non-fossil fuel sources. Finally, the company will begin using paper that's been certified by "global environmental organizations" in its manuals by next year.

Gyeong-bin Jeon the head of Samsung's Global Customer Satisfaction Center, says that the company is working to address "society's environmental issues such as resource depletion and plastic wastes," and that it wants to minimize the waste that it produces. In making the shift, Samsung pledges to use 500 thousand tons of recycled plastics and to collect 7.5 tons of discarded products by 2030.

New industry guidelines in South Korea will allow smartphone users the option of deleting unnecessary pre-installed bloatware. "The move aims to rectify an abnormal practice that causes inconvenience to smartphone users and causes unfair competition among industry players," said the Ministry of Science, ICT and Future Planning, in a press release. ZDNet reports: The measure will also help give users more data storage and improve battery life, said the ministry. Under the new guidelines, telcos are required to make most of their pre-installed apps deletable except for four necessary items related to Wi-Fi connectivity, near-field communication (NFC), the customer service center and the app store.

SpzToid shares a report from Reuters: When Danny Reagan was 13, he began exhibiting signs of what doctors usually associate with drug addiction. He became agitated, secretive and withdrew from friends. He had quit baseball and Boy Scouts, and he stopped doing homework and showering. But he was not using drugs. He was hooked on YouTube and video games, to the point where he could do nothing else. As doctors would confirm, he was addicted to his electronics. "After I got my console, I kind of fell in love with it," Danny, now 16 and a junior in a Cincinnati high school, said. "I liked being able to kind of shut everything out and just relax." Danny was different from typical plugged-in American teenagers. Psychiatrists say internet addiction, characterized by a loss of control over internet use and disregard for the consequences of it, affects up to 8 percent of Americans and is becoming more common around the world.

"We're all mildly addicted. I think that's obvious to see in our behavior," said psychiatrist Kimberly Young, who has led the field of research since founding the Center for Internet Addiction in 1995. "It becomes a public health concern obviously as health is influenced by the behavior." At first, Danny's parents took him to doctors and made him sign contracts pledging to limit his internet use. The "Reboot" program at the Lindner Center for Hope offers inpatient treatment for 11 to 17-year-olds who, like Danny, have addictions including online gaming, gambling, social media, pornography and sexting, often to escape from symptoms of mental illnesses such as depression and anxiety. âoeRebootâ patients spend 28 days at a suburban facility equipped with 16 bedrooms, classrooms, a gym and a dining hall. They undergo diagnostic tests, psychotherapy, and learn to moderate their internet use.

An anonymous reader quotes a report from Tonic: The perception of time is a fundamental process of the brain, linked tightly to attention, emotions, memory, psychiatric and neurological disorders, and even consciousness -- but while scientists have been anecdotally noting how drugs can change time perception for decades, very few have been able to address the question rigorously with tightly designed studies. Cognitive neuroscientist Devin Terhune says he's been interested in understanding the neurochemical mechanisms involved in the distortions in the perception of time, and these drugs are one way to do that. Psychedelics act on specific pathways and chemicals in the brain, and if they also change the perception of time, we could learn exactly how it happens. At the end of November, Terhune and his co-authors published a randomized, double-blind, placebo-controlled study in Psychopharmacology on the effects of microdoses of LSD on people's perception of time. They found that even at small doses, LSD seems to change the way people interpret time, though the specifics of how and when are still to be determined.

In the new work, 48 healthy people were split up into four groups. One group got a placebo, and the other three received different small doses of LSD: 5, 10, or 20 micrograms. Then, they did what's called a temporal reproduction task. In this task, you see something on a screen for a certain amount of time -- in the study it was a blue circle -- and are asked to remember and recreate how long you saw it. The participants were shown a blue circle for periods of time from 800 milliseconds all the way up to 4,000 milliseconds, in increments of 400 milliseconds. Terhune and his colleagues looked to see how accurate the different groups of people were in reproducing those intervals, and found that the people in the LSD groups tended to hold down the space bar for significantly longer periods of time than the placebo condition. The researchers call this "over-reproduction." "Terhune says that they saw these changes in time perception without any major conscious effects from the drug," the report adds. "They asked people to report if they felt anything from taking the LSD, like perceptual distortions, unusual thoughts, if they felt high, or if it affected their concentration. There were a couple of weak effects, but statistically, the change in time perception happened independent of any subjective influence of the drug."

Facebook Moments, the standalone mobile app designed to let users privately share photos and videos, is shutting down next month. "Facebook confirmed the app's services will end February 25," reports TechCrunch. "Facebook decided to end support for the app, which hasn't been updated in some time, because people weren't using it." From the report: Moments, which first launched in 2015, has seen some competition from other Facebook products recently, which might have led to its demise. For instance, Facebook built out its Stories feature, which includes a direct sharing option. That option, while designed for one-offs and not whole albums, did allow users to bypass the Moments app entirely in order to privately send photos with a select friend or friends. Users also have the option to share any of their photos from the app as Albums on Facebook. If someone downloads the app to an Album, the privacy setting will default to "Only Me" but a user always has the option to share it with friends. Facebook says it will continue to incorporate options for saving memories within the Facebook app, as well. "We're ending support for the Moments app, which we originally launched as a place for people to save their photos. We know the photos people share are important to them so we will continue offering ways to save memories within the Facebook app," Rushabh Doshi, director of product management said in a statement. If you're a Moments user, you should see a message warning you about the app's demise. You can either export your photos from any device, or create a private album on your Facebook account to retrieve your photos.

On Thursday, Tim Cook took to Twitter to celebrate the 35th anniversary of the Macintosh, recalling how it changed the world. "35 years ago, Macintosh said hello. It changed the way we think about computers and went on to change the world. We love the Mac, and today weâ(TM)re proud that more people than ever are using it to follow their passions and create the future," Cook tweeted. The Register provides a brief history lesson on how the Mac changed how users interact with computers. Here is an excerpt from the report: After the disastrous debut of the Lisa, and the abject failure of the Apple III, it was down to the Steve Jobs-led Macintosh project to save the day for the troubled computer manufacturer. Rival IBM had launched the Personal Computer XT just under a year earlier, in March 1983, with up to 640KB of RAM and a mighty Intel 8088 CPU. It also included PC-DOS 2, which would go on to underpin Microsoft's operating system efforts in subsequent decades. IBM had started to rule the PC industry, but what the IBM PC XT did not have was a graphical user interface, sticking instead with the sober command line of DOS. The Macintosh, on the other hand, had a GUI lifted from Apple's ill-fated Lisa project, except (and unusually, as things would turn out) retailed at a lower price of $2,495 (just over $6,000 in today's money). It ran faster than the Lisa too, with its Motorola 68000 CPU clocked at 7.8MHz.

The good news ended there. The machine shipped with a woeful 128KB of RAM, which was shared with the black and white 512 x 342 pixel display built into the box. That 128KB was resolutely not upgradable, and fans would have to wait until September for Apple to unleash a 512KB version for another $300. The only storage provided was a single 400KB 3 1/2;-inch disk, an improvement over the 360KB 5¼-inch floppies of IBM's PC XT and the nature of the box meant that any extra storage would have to be external. Users became quickly accustomed to swapping floppies in order to do what little useful work the pitiful 128K would afford. Third parties eventually launched hard drives for the machines, which had to be attached via the serial port. Apple would make a 20MB drive in the form of the Hard Disk 20 available in September 1985 for the 512KB Mac at a cost of $1,495. Owners of the original 128K Mac, however, needed not apply. The limited RAM made the new Hierarchical File System a non-starter.

Facebook's new plan to integrate WhatsApp, Instagram and Facebook Messenger will lead to more data about users being shared between them, a new report warns. The effort to make it easier for people to participate in conversations across its various messaging platforms sounds harmless, but it raises issues about how data will be shared across the platforms, and with third parties. The good news is that the apps will all be required to use end-to-end encryption. MIT Technology Review reports: Facebook says it wants to make it easier for people to communicate across its "ecosystem" of apps. But the real driver here is a commercial one. By making it easier to swap messages, Facebook can mine even more data to target ads with, and come up with more money-spinning services. There's another potential benefit: by integrating its messaging apps more tightly, Facebook can argue it would be harder to spin one or more of them off, as some antitrust campaigners think it should be forced to do.

Germany has laid out a $91 billion plan to phase out its use of coal by 2038, a government-appointed commission said Saturday. "Under the plan, half of the up to $91 billion will go to the regions shuttering plants in the west and east of the country, while the other half will be spent on preventing electricity prices from rising," ABS-CBN News reports. From the report: The commission agreed to the deadline after months of bitter wrangling as pressure mounts on Europe's top economy to step up its commitment to battling climate change. The panel, consisting of politicians, climate experts, unions and industry figures from coal regions, announced the deal after a final marathon session ended on Saturday morning. The commission's findings will now be passed on to the government, which is expected -- barring a surprise -- to follow the recommendations of the panel it set up. The plan will be discussed at a meeting between Chancellor Angela Merkel, Finance Minister Scholz and regional leaders on Thursday, national news agency DPA said.

Several plants using lignite or brown coal, which is more polluting than black coal, would be closed by 2022. Other plants will follow until 2030, when only 17 gigawatts of Germany's electricity will be supplied by coal, compared to today's 45 gigawatts. The last plant will close in 2038 at the latest, the commission said, but did not rule out moving this date forward to 2035 if conditions permit. The affected regions, where tens of thousands of jobs directly or indirectly linked to brown- and black-coal energy production, will receive 40 billion euros as compensation over the next two decades. Two billion euros will also be spent each year over the same period to stop customers from facing rising electricity prices.

"A 2016 document proposing cost cuts at Alphabet's Google, including fewer promotions and bonuses, sparked heated debate when it was shared inside the technology company for the first time this week," reports Bloomberg, citing people familiar with the matter. "At a companywide townhall meeting on Thursday, Chief Executive Officer Sundar Pichai fielded questions about the proposals, some of which have been implemented." From the report: The ideas were in a 2016 slide deck drafted by the company's human resources department from a brainstorming session. The document, portions of which were read to Bloomberg News, was circulated in recent days by employees via Google's internal communications systems. It detailed proposed changes to employee compensation, benefits and perks. The document also discussed how the proposals could be best presented to employees to minimize frustration, according to one of the people. That caused the most anger among some staff after the document was circulated, said this person.

Perhaps the most significant change in the proposal called for trimming the rate of promotions. Each year, a certain number of employees are up for promotions based on performance and other metrics. The slide deck suggested reducing this by 2 percentage points. The document said this could be rolled out without upsetting staff because workers didn't know what the existing rate was, so wouldn't notice if it declined. The brainstorming deck also proposed reducing wage bumps when workers get promoted. It also suggested changing Google's approach to "spot bonuses," sums that managers can award at any time of year. Managers receive emails reminding them to dispense this money. The slide deck proposed ending the emails, arguing that few people would notice. The proposal also included converting holiday gifts to staff into charitable donations -- something Google did at the end of 2016. Google confirmed the veracity of the 2016 document, although it was never presented to the company's top management.

An anonymous reader quotes a report from The New York Times: Over the last two years, Amazon has aggressively marketed its facial recognition technology to police departments and federal agencies as a service to help law enforcement identify suspects more quickly. Now a new study from researchers at the M.I.T. Media Lab has found that Amazon's system, Rekognition, had much more difficulty in telling the gender of female faces and of darker-skinned faces in photos than similar services from IBM and Microsoft. The results raise questions about potential bias that could hamper Amazon's drive to popularize the technology.

In the study, published Thursday, Rekognition made no errors in recognizing the gender of lighter-skinned men. But it misclassified women as men 19 percent of the time, the researchers said, and mistook darker-skinned women for men 31 percent of the time. Microsoft's technology mistook darker-skinned women for men just 1.5 percent of the time. For the latest study, [co-author of the study, Ms. Buolamwini, said] she sent a letter with some preliminary results to Amazon seven months ago. But she said that she hadn't heard back from Amazon, and that when she and a co-author retested the company's product a couple of months later, it had not improved. "It's not possible to draw a conclusion on the accuracy of facial recognition for any use case -- including law enforcement -- based on results obtained using facial analysis," Matt Wood, general manager of AI at Amazon Web Services, said. He added that the researchers had not tested the latest version of Rekognition, which was updated in November.

"Amazon said that in recent internal tests using an updated version of its service, the company found no difference in accuracy in classifying gender across all ethnicities," the NYT reports. The new study is scheduled to be presented Monday at an artificial intelligence and ethics conference in Honolulu.

New data on the Pentagon's domestic drone use documents 11 missions during the 2018 fiscal year. That's up from 11 missions over the entire span of 2011 through 2017, as noted by Dan Gettinger, co-director of Bard College's Center for the Study of the Drone. ZDNet reports: Most of the military's 2018 missions fell under the category of "Defense Support of Civil Authorities." That meant responding to requests from the governors of California and Oregon for support during last year's wildfire season, as well as helping the South Carolina National Guard with its Hurricane Florence flood response. Defense Department drones were also on call throughout 2018 to provide Southern Border support for a regiment of the Army. In 2018, the military also used its unmanned aerial systems (UAS) in three cases to provide Defense Department installation and airspace support. It also responded to a request from the governor of New York for support during an emergency response training exercise. And for five months during the fiscal year, it used drones to support the US Customs and Border Patrol's counterdrug operations.

With Apple offering a clearance sale on the iPhone SE earlier this week, The Verge's Nick Statt decided that it was "the appropriate moment to hop on the backup phone bandwagon" and pick one up. He writes: I've always appreciated the classic 5S design, with its overtly rounded corners and its sturdy, not-so-delicate dimensions. It never felt like it really required a case, and its smaller screen and more comfortable, one-handed use is something I've thought far too much about as I've ferried around an iPhone X and now an XS over the past year and a half. Plus, it's got a headphone jack. Would you agree that the iPhone SE is "the best minimalist phone right now," or do you think that title belongs to a different device? Why or why not?

An anonymous reader quotes a report from Ars Technica: U.S. cable Internet customers are using an average of 268.7GB per month, and 4.1 percent of households use at least 1TB, according to new research by the vendor OpenVault. Households that use at least 1TB a month are at risk of paying overage fees because of the 1TB data caps imposed by Comcast and other ISPs. Terabyte users nearly doubled year over year, as just 2.1 percent of households hit the 1TB mark last year, according to OpenVault. OpenVault found that households that face data caps use 8.5-percent less data than un-capped users, suggesting that cable customers limit their Internet usage when they face the prospect of overage fees. According to OpenVault, the caps can help cable companies avoid major network upgrades.

Specifically, "OpenVault's 2018 data also shows that average usage for households with flat-rate pricing was 282.1GB/HH, more than 9 percent higher than the 258.2GB/HH average usage for households on usage-based billing (UBB) plans," OpenVault wrote. Stated another way, customers facing caps and overage fees use 8.5-percent less data than un-capped customers. Un-capped customers are, naturally, more likely to exceed a terabyte. "The percentage of flat-rate (non-UBB) households exceeding 1TB of usage was 4.82 percent, a full percentage point higher than the 3.81 percent of UBB households who exceeded the 1TB threshold," OpenVault said. The 268.7GB average household data used in December 2018 was "up from 226.4GB/HH [household] at the end of June 2018 and a 33.3 percent increase over the YE 2017 average of 201.6GB/HH," OpenVault said. Median usage was 145.2GB in December 2018, "up from 116.4GB/HH in June 2018 and a 40 percent increase over the YE 2017 median of 103.6GB/HH," the company also said.

The Edmonton Journal reports: Recently, researchers asked more than 2,000 American and European adults their thoughts about genetically modified foods. They also asked them how much they thought they understood about GM foods, and a series of 15 true-false questions to test how much they actually knew about genetics and science in general. The researchers were interested in studying a perverse human phenomenon: People tend to be lousy judges of how much they know. Across four studies conducted in three countries -- the U.S., France and Germany -- the researchers found that extreme opponents of genetically modified foods "display a lack of insight into how much they know." They know the least, but think they know the most. "The less people know," the authors conclude, "the more opposed they are to the scientific consensus."

Science communicators have made concerted efforts to educate the public with an eye to bringing their attitudes in line with the experts," they write in the journal Nature Human Behaviour. But people with an inflated sense of what they actually know -- and most in need of education -- are also the ones least likely to be open to new information.... Extreme views often come along with not appreciating the complexity of the subject -- "not realizing how much there is to know," said Philip Fernbach, lead author of the new study and a professor of marketing at the University of Colorado Boulder. "People who don't know very much think they know a lot, and that is the basis for their extreme views."
Slashdot reader Layzej links to Rational Wiki's article on "The Backfire Effect," to illustrate Fernbach's observation that "People double down on their 'counter-scientific consensus attitudes'.

"Epecially when people feel threatened or if they are being treated as if they are stupid."
