An assessment of all life on Earth has revealed humanity's surprisingly tiny part in it as well as our disproportionate impact. From a report: The world's 7.6 billion people represent just 0.01% of all living things, according to the study. Yet since the dawn of civilisation, humanity has caused the loss of 83% of all wild mammals and half of plants, while livestock kept by humans abounds. The new work is the first comprehensive estimate of the weight of every class of living creature and overturns some long-held assumptions. Bacteria are indeed a major life form -- 13% of everything -- but plants overshadow everything, representing 82% of all living matter. All other creatures, from insects to fungi, to fish and animals, make up just 5% of the world's biomass. Another surprise is that the teeming life revealed in the oceans by the recent BBC television series Blue Planet II turns out to represent just 1% of all biomass. The vast majority of life is land-based and a large chunk -- an eighth -- is bacteria buried deep below the surface. "I was shocked to find there wasn't already a comprehensive, holistic estimate of all the different components of biomass," said Prof Ron Milo, at the Weizmann Institute of Science in Israel, who led the work, published in the Proceedings of the National Academy of Sciences.Read Replies (0)

Amazon is creating another app store, but it's not for consumers. From a report: Instead, the online retail giant will for the first time put its seal of approval on a bunch of third-party apps intended for professional sellers with its new Marketplace Appstore. It launches to sellers starting Monday, the company said. CNET reported on plans for the app store earlier this month. The new app store, which will be available in North America through Amazon's main hub for sellers called Seller Central, will include tools to handle pricing, inventory, advertising and other needs for pro sellers. The app store will be introduced to sellers slowly to ensure a smooth rollout. "Many developers have innovated and created applications that complement our tools and integrate with our service," Amazon said in a statement Monday. "We created the Marketplace Appstore to help businesses more easily discover these applications, streamline their business operations, and ultimately create a better experience for our customers."Read Replies (0)

Google is being sued in the high court for as much as $4.3 billion for the alleged "clandestine tracking and collation" of personal information from 4.4 million iPhone users in the UK. From a report: The collective action is being led by former Which? director Richard Lloyd over claims Google bypassed the privacy settings of Apple's Safari browser on iPhones between August 2011 and February 2012 in order to divide people into categories for advertisers. At the opening of an expected two-day hearing in London on Monday, lawyers for Lloyd's campaign group Google You Owe Us told the court information collected by Google included race, physical and mental heath, political leanings, sexuality, social class, financial, shopping habits and location data. Hugh Tomlinson QC, representing Lloyd, said information was then "aggregated" and users were put into groups such as "football lovers" or "current affairs enthusiasts" for the targeting of advertising. Tomlinson said the data was gathered through "clandestine tracking and collation" of browsing on the iPhone, known as the "Safari Workaround" -- an activity he said was exposed by a PhD researcher in 2012. Tomlinson said Google has already paid $39.5m to settle claims in the US relating to the practice. Google was fined $22.5m for the practice by the US Federal Trade Commission in 2012 and forced to pay $17m to 37 US states.Read Replies (0)

An anonymous reader shares a report: Several advocacy groups have banded together for a campaign that calls upon the US Federal Trade Commission to intervene and break up Facebook into smaller companies -- and more specifically to split off the Messenger, Instagram, and WhatsApp services from the mother company. The campaign, named Freedom from Facebook, was set into motion today by eight groups -- Demand Progress, Citizens Against Monopoly, Content Creators Coalition, Jewish Voice for Peace, MoveOn, Mpower Change, Open Markets Institute, and SumOfUs, respectively. Through a dedicated website, the eight advocacy groups are urging users to file a petition with the FTC on the grounds that Facebook has become a monopoly. The campaign's motto is "It's time to make Facebook safe for democracy." "Facebook and Mark Zuckerberg have amassed a scary amount of power," the campaign's website reads. "Facebook unilaterally decides the news that billions of people around the world see every day."Read Replies (0)

A coalition of human rights and technology groups released a new declaration on machine learning standards, calling on both governments and tech companies to ensure that algorithms respect basic principles of equality and non-discrimination. The Verge reports: Called The Toronto Declaration, the document focuses on the obligation to prevent machine learning systems from discriminating, and in some cases violating, existing human rights law. The declaration was announced as part of the RightsCon conference, an annual gathering of digital and human rights groups. "We must keep our focus on how these technologies will affect individual human beings and human rights," the preamble reads. "In a world of machine learning systems, who will bear accountability for harming human rights?" The declaration has already been signed by Amnesty International, Access Now, Human Rights Watch, and the Wikimedia Foundation. More signatories are expected in the weeks to come.
Beyond general non-discrimination practices, the declaration focuses on the individual right to remedy when algorithmic discrimination does occur. "This may include, for example, creating clear, independent, and visible processes for redress following adverse individual or societal effects," the declaration suggests, "[and making decisions] subject to accessible and effective appeal and judicial review."Read Replies (0)

An anonymous reader quotes a report from Scientific American: UCLA neuroscientists reported Monday that they have transferred a memory from one animal to another via injections of RNA, a startling result that challenges the widely held view of where and how memories are stored in the brain. The finding from the lab of David Glanzman hints at the potential for new RNA-based treatments to one day restore lost memories and, if correct, could shake up the field of memory and learning. The researchers extracted RNA from the nervous systems of snails that had been shocked and injected the material into unshocked snails. RNA's primary role is to serve as a messenger inside cells, carrying protein-making instructions from its cousin DNA. But when this RNA was injected, these naive snails withdrew their siphons for extended periods of time after a soft touch. Control snails that received injections of RNA from snails that had not received shocks did not withdraw their siphons for as long.
Glanzman's group went further, showing that Aplysia sensory neurons in Petri dishes were more excitable, as they tend to be after being shocked, if they were exposed to RNA from shocked snails. Exposure to RNA from snails that had never been shocked did not cause the cells to become more excitable. The results, said Glanzman, suggest that memories may be stored within the nucleus of neurons, where RNA is synthesized and can act on DNA to turn genes on and off. He said he thought memory storage involved these epigenetic changes -- changes in the activity of genes and not in the DNA sequences that make up those genes -- that are mediated by RNA. This view challenges the widely held notion that memories are stored by enhancing synaptic connections between neurons. Rather, Glanzman sees synaptic changes that occur during memory formation as flowing from the information that the RNA is carrying. The study has been published in the journal eNeuro.Read Replies (0)

Rei writes: Yesterday evening, Elon Musk announced the pricing and specs for two of the Model 3's most in-demand options -- dual motor and performance versions. The base dual motor configuration adds an AC induction front motor to the current partial-PM reluctance rear motor for $5,000; in addition to AWD and allowing the car to drive with either motor out, this cuts the 0 to 60 mph acceleration time from 5.1 seconds to 4.5 seconds. The performance package is available as a bundle, including the long-range pack, premium interior, 20" wheels, carbon fiber spoiler, and a new black-and-white interior. The vehicle will cost $78,000; 0 to 60 mph times are further cut to 3.5 seconds and the top speed increases from 140 mph to 155 mph. While these options have consistently polled as the most in-demand options not yet available, several still remain and are variously due late this year/early next year: cream interior, non-PUP, tow hitch, SR battery, and air suspension. EU-spec and China-spec are also due early next year. Production is currently over 3,500 per week, rumored to be 4,300 per week, and will be undergoing a shutdown from May 26-31 to raise production to the Q2 target of 5000-6000.Read Replies (0)

An anonymous reader quotes a report from ZDNet: At least one server used by an app for parents to monitor their teenagers' phone activity has leaked tens of thousands of accounts of both parents and children. The mobile app, TeenSafe, bills itself as a "secure" monitoring app for iOS and Android, which lets parents view their child's text messages and location, monitor who they're calling and when, access their web browsing history, and find out which apps they have installed. But the Los Angeles, Calif.-based company left its servers, hosted on Amazon's cloud, unprotected and accessible by anyone without a password. "We have taken action to close one of our servers to the public and begun alerting customers that could potentially be impacted," said a TeenSafe spokesperson told ZDNet on Sunday. The database stores the parent's email address associated with their associated child's Apple ID email address. It also includes the child's device name -- which is often just their name -- and their device's unique identifier. The data contains the plaintext passwords for the child's Apple ID. Because the app requires that two-factor authentication is turned off, a malicious actor viewing this data only needs to use the credentials to break into the child's account to access their personal content data.Read Replies (0)

A scientific paper, originally published in March, from peer-reviewed journal Progress in Biophysics and Molecular Biology has found its way in this week's news-cycle. The paper, which is co-written by 33 authors including molecular immunologist Edward Steele and astrobiologist Chandra Wickramasinghe, suggests that octopuses could be aliens, adding legitimacy to a belief, which otherwise has been debunked several times in the recent years. An excerpt from the paper, which makes the bold claim: The genetic divergence of Octopus from its ancestral coleoid sub-class is very great ... Its large brain and sophisticated nervous system, camera-like eyes, flexible bodies, instantaneous camouflage via the ability to switch color and shape are just a few of the striking features that appear suddenly on the evolutionary scene. [...] It is plausible then to suggest they [octopuses] seem to be borrowed from a far distant 'future' in terms of terrestrial evolution, or more realistically from the cosmos at large."Ephrat Livni of Quartz questions the basis of the finding: To make matters even more strange, the paper posits that octopuses could have arrived on Earth in "an already coherent group of functioning genes within (say) cryopreserved and matrix protected fertilized octopus eggs." And these eggs might have "arrived in icy bolides several hundred million years ago." The authors admit, though, that "such an extraterrestrial origin...of course, runs counter to the prevailing dominant paradigm." Indeed, few in the scientific community would agree that octopuses come from outer space. But the paper is not just about the provenance of cephalopods. Its proposal that octopuses could be extraterrestrials is just a small part of a much more extensive discussion of a theory called "panspermia," which has its roots in the ideas of ancient Greece. Newsweek spoke with Avi Loeb, the Frank B. Baird Jr. Professor of Science at Harvard University, who told the publication that the paper has raised "an interesting but controversial possibility." However, he added, that it offers no "indisputable proof" that the Cambrian explosion is the result of panspermia. Further reading: Cosmos magazine has outlined some flaws in the assumptions that the authors made in the paper. It has also looked into the background of some of the authors. The magazine also points out that though the paper has made bold claims, it has yet to find support or corroboration from the scientific community. News outlet Live Science has also questioned the findings.Read Replies (0)

MSNBC recently published a video of Bill Gates telling his staff at the Gates Foundation that he had two meetings with Donald Trump since the president was elected. In the video, Gates says Trump doesn't know the difference between two sexually transmitted diseases -- human papillomavirus (HPV) and human immunodeficiency virus (HIV) -- and that it was "scary" how much Trump knew about Gates' daughter's appearance. Gates also said he urged Trump to support innovation and technology during those meetings. CNN reports: Taking audience questions about his interactions with Trump at a Bill & Melinda Gates Foundation meeting, the former Microsoft honcho said he first met Trump in December 2016. He told the audience that Trump had previously come across his daughter, Jennifer, at a horse show in Florida. "And then about 20 minutes later he flew in on a helicopter to the same place," Gates said, according to video of the event broadcast by MSNBC late Thursday. "So clearly he had been driven away but he wanted to make a grand entrance in a helicopter. "Anyway, so when I first talked to him, it was actually kind of scary how much he knew about my daughter's appearance. Melinda (Gates' wife) didn't like that too well."
Gates also said he discussed science with Trump on two separate occasions, where he says the President questioned him on the difference between HIV and HPV. "In both of those two meetings, he asked me if vaccines weren't a bad thing because he was considering a commission to look into ill-effects of vaccines and somebody -- I think it was Robert Kennedy Jr. -- was advising him that vaccines were causing bad things. And I said no, that's a dead end, that would be a bad thing, don't do that. "Both times he wanted to know if there was a difference between HIV and HPV so I was able to explain that those are rarely confused with each other," Gates said.Read Replies (0)

It's been almost a year since RED, a company known for its high-end $10,000+ cameras, teased a smartphone called the RED Hydrogen One. Several months have passed since the phone was announced and we still don't know much about it, aside from it having a very industrial design and "Hydrogen holographic display." Earlier this week, AT&T and Verizon confirmed that they'll launch the device later this year. Now, The Verge's Dieter Bohn has shared his hands-on impressions with the device, which he claims to be "one of the most ambitious smartphones in years from a company not named Apple, Google, or Samsung." Here's an excerpt from the report: The company better known for high-end 4K cameras with names like "Weapon" and "Epic-w" isn't entering the smartphone game simply to sell you a better Android phone. No, this phone is meant to be one piece of a modular system of cameras and other media creation equipment -- the company claims it will be "the foundation of a future multi-dimensional media system." To that end, it has a big set of pogo-pins on the back to connect it to RED's other cameras also to allow users to attach (forthcoming) modules to it, including lens mounts. If it were just a modular smartphone, we'd be talking about whether we really expected the company to produce enough modules to support it.
