sciencehabit writes You can credit your existence to tiny wormlike creatures that lived 500 million years ago, a new study suggests. By tunneling through the sea floor, scientists say, these creatures kept oxygen concentrations at just the right level to allow animals and other complex life to evolve. The finding may help answer an enduring mystery of Earth's past. The idea is that as they dug and wiggled, these early multicellular creatures—some were likely worms as long as 40 cm—exposed new layers of seafloor sediment to the ocean's water. Each new batch of sediment that settles onto the sea floor contains bacteria; as those bacteria were exposed to the oxygen in the water, they began storing a chemical called phosphate in their cells. So as the creatures churned up more sediment layers, more phosphate built up in ocean sediments and less was found in seawater. Because algae and other photosynthetic ocean life require phosphate to grow, removing phosphate from seawater reduced their growth. Less photosynthesis, in turn, meant less oxygen released into the ocean. In this way, the system formed a negative feedback loop that automatically slowed the rise in oxygen levels as the levels increased.

An anonymous reader writes Having completed his 31-day stretch underwater, Fabien Cousteau, grandson of famed oceanographer Jacques Cousteau, shows off his underwater laboratory to PBS in this video. When asked about his observations' Fabien said' "It's just amazing, we've seen so much new behavior that I've never seen before. Fish sleeping in sponges, a goliath grouper attacking a barracuda, never seen that before, I don't think anyone has ever caught it on film before. Christmas tree worms, spawning and giving off this milky smoke like stuff off. I mean it's just science fiction, it's really amazing down here. And that's why we're down here, my grandfather used to say, in order to film a fish you must become a fish. So we're trying to get as close as we can to becoming fish."
sciencehabit (1205606) writes "Every day, our cells manufacture small amounts of a molecule that, in higher doses, might be the key to leading a longer, healthier life. A team of researchers has found that this molecule boosts the lifespan of worms by more than 50%, raising the possibility that it will increase human longevity. Dietary supplements that contain the molecule and allegedly build muscle are already on the market. The study drops a barbell on their use, however, by suggesting that the molecule may actually thwart muscle growth."
mdsolar (1045926) writes in about a Norwegian team who believe they have an explanation about the unique distribution of HIV in Africa. "While around the world a vast majority of AIDS victims are men, Africa has long been the glaring exception: Nearly 60 percent are women. And while there are many theories, no one has been able to prove one. In a modest public health clinic behind a gas station here in South Africa's rural KwaZulu/Natal Province, a team of Norwegian infectious disease specialists think they may have found a new explanation. It is far too soon to say whether they are right. But even skeptics say the explanation is biologically plausible. And if it is proved correct, a low-cost solution has the potential to prevent thousands of infections every year. The Norwegian team believes that African women are more vulnerable to H.I.V. because of a chronic, undiagnosed parasitic disease: genital schistosomiasis (pronounced shis-to-so-MY-a-sis), often nicknamed 'schisto.' The disease, also known as bilharzia and snail fever, is caused by parasitic worms picked up in infested river water. It is marked by fragile sores in the far reaches of the vaginal canal that may serve as entry points for H.I.V., the virus that causes AIDS. Dr. Eyrun F. Kjetland, who leads the Otimati team, says that it is more common than syphilis or herpes, which can also open the way for H.I.V."
Nerval's Lobster writes "The remote-access management flaw that allowed TheMoon worm to thrive on Linksys routers is far from the only vulnerability in that particular brand of hardware, though it might be simpler to call all home-based wireless routers gaping holes of insecurity than to list all the flaws in those of just one vendor. An even longer list of Linksys (and Cisco and Netgear) routers were identified in January as having a backdoor built into the original versions of their firmware in 2005 and never taken out. Serious as those flaws are, they don't compare to the list of vulnerabilities resulting from an impossibly complex mesh of sophisticated network services that make nearly every router aimed at homes or small offices an easy target for attack, according to network-security penetration- and testing services. For example, wireless routers (especially home routers owned by technically challenged consumers) are riddled with security holes stemming from design goals that emphasize usability over security, which often puts consumers at risk from malware or attacks on devices they don't know how to monitor, but through which flow all their personal and financial information via links to online banking, entertainment, credit cards and even direct connections to their work networks, according to a condemnation of the Home Network Administration Protocol from Tenable Network Security. Meanwhile, a January 2013 study from Rapid7 found 40 million to 50 million network-enabled devices, including nearly all home routers, were vulnerable to exploits using UPnP. Is there any way to fix this target-rich environment?" If only there were an easily upgradeable open source router operating system to which vendors could add support for their hardware leaving long term maintenance to a larger community.
UnderAttack writes "A vulnerability in many Linksys routers, allowing for unauthenticated code execution, is being used to mass-exploit various Linksys routers right now. Infected routers will start scanning for vulnerable systems themselves, leading to a very fast spread of this 'worm.'"
the_newsbeagle writes "When surgeons set out to repair holes in the walls of the heart's chambers or in blood vessels, they often do invasive open-heart surgery and use sutures, staples, and glue to keep a patch in place. But the sutures and staples are a rough fix, and many of the glues on the market today don't work well on wet tissue that's continually flexed by the heart's contractions and the movement of pumping blood. Today biomaterial researchers announced a new light-activated glue that could make surgery less invasive, quicker, and easier. The adhesive was inspired by slugs' and sandcastle worms' sticky secretions, which work underwater, and it can be applied with slender tools during minimally invasive surgery. A flash of UV light then sets the glue, which bends and flexes with the tissue."
Rambo Tribble writes "An article in Current Biology (abstract) details the finding that minute particles of plastic waste are affecting marine worms, potentially having grave impacts on marine biodiversity (PDF) and leading to the accumulation of toxins in marine animals. 'The team found that the tiny bits of plastic, which measure 1mm or smaller, transferred pollutants and additive chemicals — such as flame-retardants — into the guts of lugworms (Arenicola marina). This process results in the chemical reaching the creatures' tissue, causing a range of biological effects such as thermal stress and the inability to consume as much sediment.' Unfortunately, policymakers have routinely treated such wastes as benign. The BBC provides more approachable coverage of the findings."
Hugh Pickens DOT Com writes "The Boston Globe reports that the pending use of GPS tracking devices, slated to be installed in Boston police cruisers, has many officers worried that commanders will monitor their every move. Boston police administrators say the system gives dispatchers the ability to see where officers are, rather than wait for a radio response and supervisors insist the system will improve their response to emergencies. Using GPS, they say, accelerates their response to a call for a shooting or an armed robbery. 'We'll be moving forward as quickly as possible,' says former police commissioner Edward F. Davis. 'There are an enormous amount of benefits. . . . This is clearly an important enhancement and should lead to further reductions in crime.' But some officers said they worry that under such a system they will have to explain their every move and possibly compromise their ability to court street sources. 'No one likes it. Who wants to be followed all over the place?' said one officer who spoke anonymously because department rules forbid police from speaking to the media without authorization. 'If I take my cruiser and I meet [reluctant witnesses] to talk, eventually they can follow me and say why were you in a back dark street for 45 minutes? It's going to open up a can of worms that can't be closed.' Meanwhile civil libertarians are relishing the rank and file's own backlash. 'The irony of police objecting to GPS technology for privacy reasons is hard to miss in the aftermath of United States v. Jones,' says Woodrow Hartzog. 'But the officers' concerns about privacy illustrate just how revealing GPS technology can be. Departments are going to have to confront the chilling effect this surveillance might have on police behavior.'"
wiredmikey writes "According to a recent survey of malware analysts at U.S. enterprises, 40% of the time a device used by a member the senior leadership team became infected with malware was due to executives visiting a pornographic website. The study, from ThreatTrack Security, also found that nearly six in 10 of the malware analysts have investigated or addressed a data breach that was never disclosed by their company. When asked to identify the most difficult aspects of defending their companies' networks from advanced malware, 67% said the complexity of malware is a chief factor; 67% said the volume of malware attacks; and 58% cited the ineffectiveness of anti-malware solutions."
First time accepted submitter calinduca writes "Artificial blood that could one day be used in humans without side effects has been created by scientists in Romania. The blood contains water and salts along with a protein known as hemerythrin which is extracted from sea worms. Researchers from Babe-Bolyai University in Cluj-Napoca, Romania, hope it could help end blood supply shortages and prevent infections through donations." Wikipedia's entry on hemerythrin explains its unusual oxygen binding mechanism.
sciencehabit writes "When you drop a whale backbone into Antarctic waters and retrieve it a year later, you'll find it covered with a pelt of wriggling, rosy-hued worms. Drop a chunk of wood in the same spot, and you'll discover that it's hardly changed. That's the result of a simple experiment to find out if some of the world's weirdest worms also live in Antarctic waters. The discovery extends the range of bone-eating worms to the Southern Ocean and suggests that Antarctic shipwrecks may be remarkably intact."
New submitter m.alessandrini writes "I've been using Debian for a long time, and I'm not a novice at all; I install system updates almost daily, I avoid risky behaviors on Internet, and like all Linux users I always felt safe. Yesterday my webcam suddenly turned on, and turned off after several minutes. I'm pretty sure it was nothing serious, but I started thinking about malware. At work I use noscript and other tools, but at home I have a more relaxed browser to be used by other family members, too. Here I'm not talking about rootkits or privilege escalation (I trust Debian), I think more of normal user compromise. For example, these days much malware come from malicious scripts in sites, even in advertising banners inside trusted sites, and this is more 'cross-platform' than normal viruses. So, what about non-root user malware? How much could this be real? And how can you diagnose it?"
An anonymous reader writes "German IT magazine Heise reports (original in German) that the Ministry of Education in Schwerin had a Conficker virus infection on 170 machines, that was dealt with by simply throwing them on the trash. Other German authorities have now decided that 'the approach taken is not up to the principle of efficiency and economy' and that the 187,300 Euro invested in this radical form of virus removal were inappropriate. The ministry had earlier estimated the cost of cleaning their desktops and servers by more conventional means to 130,000 Euro."
chicksdaddy writes "To paraphrase a quote attributed to F. Scott Fitzgerald: 'Rich countries aren't like everyone else. They have less malware.' That's the conclusion of a special Security Intelligence Report from Microsoft, anyway. The special supplement, released on Wednesday, investigated the links between rates of computer infections and a range of national characteristics including the relative wealth of a nation, observance of the rule of law and the rate of software piracy. The conclusion: cyber security (by Microsoft's definition: low rates of malware infection) correlated positively with many characteristics of wealthy nations – high Gross Income Per Capita, higher broadband penetration and investment in R&D and high rates of literacy. It correlated negatively with characteristics common in poorer nations – like demographic instability, political instability and lower levels of education.'"
Iranian state TV is claiming that the country has successfully sent a monkey into space and back, bringing Iran one step closer to its goal of a manned space flight. According to the report, the rocket named Pishgam, or Pioneer in Farsi, reached a height of 120km. From the article: "Iran has long said it seeks to send an astronaut into space as part of its ambitious aerospace program, including plans for a new space center announced last year. In 2010, Iran said it launched an Explorer rocket into space carrying a mouse, a turtle and worms."

derekmead writes "Billions worldwide still don't have access to proper sanitation, and those that do still require a ton of water and electricity to keep waste flowing. A French company is offering one solution: Use turd-eating worms to compost waste right at the source. Ecosphere Technologies has developed an outhouse that, rather than relying on chemicals like a port-a-john, relies on about a pound of red wiggler worms. A new installation in Quebec uses imported worms, placed inside of a mixture of dung and straw underneath to toilet, to devour feces delivered to them by a conveyor belt system. (When someone uses the toilet, pee filters through sand to wash away, while a pedal allows the user to transport their poo to the worm space.) The whole system uses no water or electricity, and a series of passive vents allegedly keeps the toilet smelling great. The company claims it can be used 10,000 times without servicing, which is far better than what a port-a-potty can boast, although with a current price tag of $40k for the worm system, port-a-potties are still a lot cheaper."
New submitter The name is Dave. Ja debuts on the front page with the most dismal news of our time: "This is truly 'Stuff That Matters'. Where would civilization be today without bacon? I don't mean to be alarmist but ... sound the alarms! This is big — it could lead to civil unrest." Yes, a bacon shortage. Hopefully what bacon there is will be more delicious after being fed with gummi worms.
