Oceans Could Soon Not Have Enough Oxygen To Support Marine Life

Slashdot - 1 hour 29 sec ago
An anonymous reader writes: As the climate continues to change in response to the increasing amount of carbon humans pump into the atmosphere, the oceans are being particularly hard hit from melting Arctic sea ice, acidification, and warming surface temperatures. Yet those are not the only difficulties that marine life has to deal with, as a new study reports that the oceans are also losing oxygen. As the majority of marine life relies on the oxygen dissolved in the oceans, it is worrying that noticeable differences have been observed in the gas concentrations in the world's waters. The reduction in oxygen will have profound effects on ocean biodiversity, though as the study published in Global Biogeochemical Cycles shows, not all regions will be affected in the same way or over the same period of time."Loss of oxygen in the ocean is one of the serious side effects of a warming atmosphere, and a major threat to marine life," said lead author Matthew Long of the National Center for Atmospheric Research. "Since oxygen concentrations in the ocean naturally vary depending on variations in winds and temperature at the surface, it's been challenging to attribute any deoxygenation to climate change. This new study tells us when we can expect the impact from climate change to overwhelm the natural variability."

Ubuntu Founder Pledges No Back Doors In Linux

Slashdot - 1 hour 40 min ago
Mark Shuttleworth, founder of Canonical and Ubuntu Foundation, gave an interview to eWeek this week ahead of Ubuntu Online Summit (UOS). In the wide-ranging interview, Shuttleworth teased some features that we could expect in Ubuntu 16.10, and also talked about security and privacy. From the report: One thing that Ubuntu Linux users will also continue to rely on is the strong principled stance that Shuttleworth has on encryption. With the rapid growth of the Linux Foundation's Let's Encrypt free Secure Sockets Layer/Transport Layer Security (SSL/TLS) certificate platform this year, Shuttleworth noted that it's a good idea to consider how that might work in an integrated way with Ubuntu. Overall, he said, the move to encryption as a universal expectation is really important. "We don't do encryption to hide things; we do encryption so we can choose what to share," Shuttleworth said. "That's a profound choice we should all be able to make." Shuttleworth emphasized that on the encryption debate, Canonical and Ubuntu are crystal clear. "We will never backdoor Ubuntu; we will never weaken encryption," he said.

Lab-Grown Meat Is In Your Future, and It May Be Healthier Than the Real Stuff

Slashdot - 2 hours 20 min ago
An anonymous reader shares an article on The Sydney Morning Herald:Scientists and businesses working full steam to produce lab-created meat claim it will be healthier than conventional meat and more environmentally friendly. But how much can they improve on old-school pork or beef? In August 2013, a team of Dutch scientists showed off their lab-grown burger (cost: $435,000) and even provided a taste test. Two months ago, the American company Memphis Meats fried the first-ever lab meatball (cost: $23,700 per pound). Those who have tasted these items say they barely differ from the real deal. The Dutch and the Americans claim that within a few years lab-produced meats will start appearing in supermarkets and restaurants. And these are not the only teams working on cultured meat (as they prefer to call it). Another company, Modern Meadow, promises that lab-grown "steak chips" -- something between a potato chip and beef jerky -- will hit the stores in the near future, too.

Tim Cook Defends Apple, Teases Exciting New Products In The Pipeline

Slashdot - 3 hours 15 min ago
anderzole quotes a report from BGR: Apple's earnings report last week saw the company report a year over year decline in profits for the first time since 2003. The biggest contributing factor to the decline, not surprisingly, is that year over year iPhone sales dropped by 16%. Notably, Apple's most recent quarter represents the company's first iPhone sales decline in history. Consequently, the usual contingent of pundits and analysts have come out of the woodwork, all exclaiming that we've reached 'peak iPhone' and that Apple at this point has nowhere to go but down. In an effort to inject a bit of good news and all-around optimism to a particularly negative Apple news cycle, Tim Cook earlier today appeared on CNBC with Jim Cramer where the Apple CEO teased that Apple's still has a lot of innovation left to do and some interesting items in the product pipeline. "We've got great innovation in the pipeline," Cook said to Cramer. "New iPhones that will incentivize you and other people that have iPhones today to upgrade to new iPhones. We are going to give you things you can't live without that you just don't know you need today. That has always been the objective of Apple is to do things that really enrich people's lives. That you look back on and you wonder, how did I live without this."

Researchers Solve One Of The Biggest Mysteries About How Water Flows On Mars

Slashdot - 6 hours 18 min ago
An anonymous reader writes: Not only is water flowing on Mars, it's also boiling. This experiment published today in Nature Geoscience solves one of the major mysteries about the surface of the red planet. Gizmodo writes, "Researchers built a chamber simulating the conditions and atmosphere of Mars, then put ice in there to melt. The ice did melt and the water from it flowed -- but there was also a surprise. The surface of the water boiled as it flowed, and that boiling was strong enough to move not just the water but also dirt and debris surrounding the streams. Importantly, temperature was not the major factor in this boiling water, it was due to the pressure of the atmosphere." You may remember pictures of flowing water on Mars which surfaced last year. One would think the summer temperatures should be too cold for water to flow on Mars (as seen in the images), however, the water that flows on Mars is a salty-brine which lowers the freezing point of the water. So how does the water manage to carve out the landscape so quickly and visibly? Easy: the boiling water theory. Boiling water hits a boiling stage along its surface, where it kicks up dust and dirt and debris in the water's wake. The research team did see the boiling water move debris, but they also saw collapses along the sides of the flows. The boiling and disturbance it causes etches those lines on Mars clearly enough for satellites to notice them.

Novel Model Illustrates The Finer Details Of Nuclear Fission

Slashdot - 9 hours 17 min ago
mdsolar quotes a report from Phys.Org: For nearly 80 years, nuclear fission has awaited a description within a microscopic framework. In the first study of its kind, scientists collaborating from the University of Washington, Warsaw University of Technology (Poland), Pacific Northwest National Laboratory, and Los Alamos National Laboratory, developed a novel model to take a more intricate look at what happens during the last stages of the fission process. Using the model, they determined that fission fragments remain connected far longer than expected before the daughter nuclei split apart. Moreover, they noted the predicted kinetic energy agreed with results from experimental observations. This discovery indicates that complex calculations of real-time fission dynamics without physical restrictions are feasible and opens a pathway to a theoretical microscopic framework with abundant predictive power.

China Creates World's First Graphene Electronic Paper

Slashdot - May 2, 2016 - 22:33
An anonymous reader writes from a report published on Tech Times: China has developed the world's first graphene electronic paper that can possibly revolutionize the screen displays on electronic gadgets such as wearable devices and e-readers. Developed by Guangzhou OED Technologies in partnership with another company in the Chongqing Province, the material is also the world's lightest and strongest material in prevalence today. It's 0.335 nanometers thick and can be used to create hard or flexible graphene displays. Graphene e-paper comes with the capability to conduct both heat and electricity, and it can supposedly enhance optical displays to a brighter level, owing to its high-light transmittance properties. What about cost? Since it's derived from carbon, graphene-based e-papers can be easily produced cost-effectively. Traditional e-papers use indium metal for their display, which is very expensive and rare to source.

UAE To Build Artificial Mountain To Improve Rainfall

Slashdot - May 2, 2016 - 21:10
An anonymous reader writes: The United Arab Emirates is in the early stages of developing an artificial mountain that would force air upwards and create clouds that could produce additional rainfall. While the Middle East and Africa continues to get hotter, researchers are further motivated and more desperate for solutions to maximize rainfall. "Building a mountain is not a simple thing," said NCAR scientist and lead researcher Roelof Bruintjes. "We are still busy finalizing assimilation, so we are doing a spread of all kinds of heights, widths and locations [as we simultaneously] look at the local climatology." The specific location has yet to be decided on as the team is still testing out different sites across the UAE. "If [the project] is too expensive for [the government], logically the project won't go through, but this gives them an idea of what kind of alternatives there are for the long-term future." Bruintjes said. "If it goes through, the second phase would be to go to an engineering company and decide whether it is possible or not."

Kim Jong-Un Bans All Weddings, Funerals And Freedom Of Movement In North Korea

Slashdot - May 2, 2016 - 20:27
An anonymous reader quotes a report from The Independent: Weddings and funerals have been banned and Pyongyang is in lockdown as preparations for a once-in-a-generation party congress get underway in North Korea. The ruling Worker's Party of Korea, headed by the country's leader, Kim Jong-un, is due to stage the first gathering of its kind for 36 years on Friday. Free movement in and out of the capital has also been forbidden and there has been an increase in inspections and property searches, according to Daily NK, which claims to have sources in the country. The temporary measures are said to be an attempt to minimize the risk of "mishaps" at the event, according to Cheong Joon-hee, a spokesman at South Korea's Unification Ministry. Meanwhile, North Korea has been conducting missile tests left and right, many of which have failed miserably.

LG's New Fingerprint Sensor Doesn't Need A Button

Slashdot - May 2, 2016 - 19:44
An anonymous reader quotes a report from Mashable: LG Innotek has developed a fingerprint sensor that's placed under a glass surface instead of in a physical button, the company announced Sunday. The new sensor could lead to smartphones that you can unlock by placing your finger on the phone screen. The LG-owned electronics parts manufacturer achieved this by cutting out a 0.01-inch thick slot in the lower part of a smartphone's cover glass, and then inserting a very thin fingerprint sensor into it. In other words, the sensor is still under the cover glass, but the slot moves the sensor close enough to the surface to read a fingerprint. That way, the sensor is protected from water and scratches, and can be installed anywhere under the phone's glass surface.

China Probes Baidu Over False Medical Ads After Student Dies

Slashdot - May 2, 2016 - 19:01
hackingbear writes: China's Internet regulator said on Monday it will send a team to investigate Baidu Inc over the death of a university student who used the Chinese search engine to look for treatment for his rare cancer, and to find an experimental treatment offered by the Second Hospital of Beijing Armed Police Corps, which eventually proved ineffective. Before dying, Wei accused Baidu online of promoting false medical information, as well as the hospital for misleading advertising in claiming a high success rate for the treatment, state radio said. The post attracted a large public outcry. Baidu says around one quarter of its revenues come from medical and health-care advertisers.

Self-Driving Features Could Lead To More Sex In Moving Cars, Expert Warns

Slashdot - May 2, 2016 - 18:18
An anonymous reader writes: According to CBC.ca, "At least one expert is anticipating that, as the so-called 'smart' cars get smarter, there will eventually be an increase in an unusual form of distracted driving: hanky-panky behind the wheel." Barrie Kirk of the Canadian Automated Vehicles Centre of Excellence said, "I am predicting that, once computers are doing the driving, there will be a lot more sex in cars. That's one of several things people will do which will inhibit their ability to respond quickly when the computer says to the human, 'Take over.'" Federal officials, who have been tasked with building a regulatory framework to govern driverless cars, highlighted their concerns in briefing notes compiled for Transport Minister Marc Garneau. "Drivers tend to overestimate the performance of automation and will naturally turn their focus away from the road when they turn on their auto-pilot," said the note. The Tesla autopilot feature has been receiving the most criticism as there have been many videos posted online showing Tesla drivers engaged in questionable practices, including reading a newspaper or brushing their teeth.

Greenpeace Leaks Big Part Of Secret TTIP Documents

Slashdot - May 2, 2016 - 17:35
An anonymous reader writes: The environmental group Greenpeace has obtained 248 pages of classified documents from the Transatlantic Trade and Investment Partnership (TTIP) trade talks. The group warns EU standards on the environment and public health risk being undermined by compromises with the US, specifically that US corporations may erode Europe's consumer protections. The TTIP would "harmonize regulations across a huge range of business sectors, providing a boost to exporters on both sides of the Atlantic," writes the BBC. After the Greenpeace leak was published, EU Trade Commissioner Cecilia Malmstroem said in her blog, "I am simply not in the business of lowering standards." Meanwhile, Greenpeace EU director Jorgo Riss said, "These leaked documents confirm what we have been saying for a long time: TTIP would put corporations at the center of policy-making, to the detriment of environment and public health." You can be the judge for yourself. The leaked documents are available for download here.

Climate-Exodus Expected In The Middle East And North Africa

Slashdot - May 2, 2016 - 16:53
An anonymous reader quotes a report from Phys.Org: Researchers of the Max Planck Institute for Chemistry and the Cyprus Institute in Nicosia have calculated that the Middle East and North Africa could become so hot that human habitability is compromised. The goal of limiting global warming to less than two degrees Celsius, agreed at the recent UN climate summit in Paris, will not be sufficient to prevent this scenario. The result is deeply alarming: Even if Earth's temperature were to increase on average only by two degrees Celsius compared to pre-industrial times, the temperature in summer in these regions will increase more than twofold. This means that during hot days temperatures south of the Mediterranean will reach around 46 degrees Celsius (approximately 114 degrees Fahrenheit) by mid-century. Such extremely hot days will occur five times more often than was the case at the turn of the millennium. In combination with increasing air pollution by windblown desert dust, the environmental conditions could become intolerable and may force people to migrate.

20-Yr-Old Compaq Laptop Is Still Crucial to Maintaining McLaren's Multi-Million Dollar Cars

Slashdot - May 2, 2016 - 16:10
An anonymous reader writes: It may come as a surprise to many, but the 20-year-old Compaq LTE 5280 still plays a vital role in maintaining multi-million dollar McLaren F1s. Jalopnik recently visited McLaren's Special Operations workshop where it found several of Compaq's old laptops serving their masters. Why do they rely on these dated computers, you ask? A McLaren Special Operations staff explains, "The reason we need those specific Compaq laptops is that they run a bespoke CA card which is installed into them. The CA card is an interface between the laptop software (which is DOS based) and the car. We are currently working on a new interface which will be compatible with modern laptops as the old Compaqs are getting less and less reliable and harder to find." For those wondering, the Compaq LTE 5280 comes with a 120MHz Intel Pentium processor, up to "80MB" of RAM, and up to 1.2GB of HDD.

Samsung, Nvidia End Their Patent Lawsuits

Slashdot - May 2, 2016 - 15:40
Reader itwbennett writes: In September 2014, Nvidia sued both Samsung and Qualcomm, asking for shipments of Galaxy phones and tablets with graphics processors from Qualcomm, ARM and Imagination Technologies to be blocked. Samsung fired back, suing Nvidia for patent infringement, and for supposedly false claims by Nvidia that its Tegra K1 was the world's fastest mobile processor. Now, in an agreement announced today, Nvidia and Samsung have agreed to 'settle all outstanding IP litigation'. Under the agreement, the companies will license 'a small number' of patents to each other, though they said there's no broad cross-license agreement. There's also no financial payment. And no mention was made of Qualcomm.
