    The new EPI Life mobile phone comes complete with mini electrocardiogram. "We think it's a revolution. It has clinical significance," EPI medical chief Dr. Chow U-Jin said at the mobile industry's annual conference in Barcelona. "Anywhere in the world you can use it as a phone but you are also able to transfer an ECG and get a reply," Chow said. "If you get a normal reply it will just be an SMS," he added. "If it's severe, you get a call: 'Sir, an ambulance is on the way'." EPI Life has three hospitals in Singapore, all of which carry the phone users' history. EPI Life costs $700 (516 euros), the price of a top range smartphone, and 2,000 of them have been on the market since 2010.

Force of nature gave life its asymmetry : Nature News & Comment - 0 views

  • In an experiment that took 13 years to perfect1, the researchers have found that these electrons tend to destroy certain organic molecules slightly more often than they destroy their mirror images.
  • The weak nuclear force, which is involved in nuclear decay, is the only force of nature known to have a handedness preference: electrons created in the subatomic process known as β decay are always 'left-handed'. This means that their spin — a quantum property analogous to the magnetization of a bar magnet — is always opposite in direction to the electron's motion.
  • In all cases the asymmetry was tiny, but consistent, like flipping a not-quite-fair coin. “The scale of the asymmetry is as though we flip 20,000 coins again and again, and on average, 10,003 of them land on heads while 9,997 land on tails,” says Dreiling.

  • the bacteria appear to be reproducing normally and passing on the new X-Y pair to their offspring.
  • t probably wouldn't survive for very long, Romesberg said, because it needs to feed on synthetic molecules to replicate — molecules that only the scientists can supply.

  • The authors of the article note several similarities with the bizarre and enigmatic soft-bodied life forms that lived between 635 and 540 million years ago - the span of Earth history known as the Ediacaran Period.
  • The authors of the paper recognise two new species of mushroom-shaped animal: Dendrogramma enigmatica and Dendrogramma discoides.
  • The new organisms are multicellular but mostly non-symmetrical, with a dense layer of gelatinous material between the outer skin cell and inner stomach cell layers. The researchers did find some similarities to other animal groupings, such as the Cnidaria - the phylum that comprises corals and jellyfish - and the Ctenophora, which includes the marine organisms known as comb jellies. But the new organisms did not fulfil all the criteria required for inclusion in either of those categories.

  • One way to resolve the question surrounding Dendrogramma's affinities would be to examine its DNA, but new specimens will need to be found. The original samples were first preserved in formaldehyde and later transferred to 80% alcohol, a mode of treatment that prevents analysis of genetic material.

  • Mars almost definitely has water below its surface, and it’s possible that it might have life there too -- buried deep in the soil, where it’s protected from dryness, radiation and temperature extremes. Unfortunately, NASA doesn’t seem too interested in looking for it, preferring to look for "conditions" that might support life instead. But a group of aerospace and robotics engineers -- many of whom work for NASA, and one of whom even operates the Curiosity rover -- think NASA should be going with a more direct approach, and they're taking matters into their own hands.

  • "deny, disrupt, degrade and deceive" by any means possible.
  • According to reports in Der Spiegel last year, British intelligence has tapped the reservations systems of over 350 top hotels around the world for the past three years to set up Royal Concierge. It was used to spy on trade delegations, foreign diplomats, and other targets with a taste for the high life.
  • A PowerPoint presentation from 2010 states that JTRIG activities account for five per cent of GCHQ's operations budget and uses a variety of techniques. These include "call bombing" to drown out a target's ability to receive messages, attacking targets in hotels, Psyops (psychological operations) against individuals, and going all the way up to disrupting a country's critical infrastructure.

  • Targets can also be discredited with a "honey trap", whereby a fake social media profile is created, maybe backed up by a personal blog to provide credibility. This could be used to entice someone into making embarrassing confessions, which the presentation notes described as "a great option" and "very successful when it works."

  • Android threats are primarily a non-US problem
  • F-Secure believes it would be incorrect to say that “Google hasn’t been actively making efforts to increase the security of the Android platform.”
  • At the very bottom of the list was Google Play itself, with the lowest percentage of malware in the gathered samples: 0.1 percent. F-Secure also noted that “the Play Store is most likely to promptly remove nefarious applications, so malware encountered there tends to have a short shelf life.”

  • “If this pans out, it’s potentially the biggest news in the outer Solar System since the discovery of the Enceladus plume,” says Robert Pappalardo, a planetary scientist at the Jet Propulsion Laboratory in Pasadena, California, who was not involved in the research.
  • Roth’s team spotted the plumes when Europa was at its greatest distance from Jupiter. Changing stresses in the moon's crust, caused by tidal forces between the moon and planet, may explain why the researchers didn't see any plumes in the November observation when Europa and Jupiter were close. “Maybe Europa is just burping once in a while,” Pappalardo says.

  • t's a messaging app for iOS.
  • based on peer-to-peer “mesh networking” and connects to nearby phones using Bluetooth and WiFi, with connectivity increasing as more people use it in an area.
  • In Hong Kong mostly, where pro-democracy protesters are using it to communicate amid fears of network shutdowns. It's also been used by Iraqis and Taiwanese students during their anti-Beijing Sunflower Movement. Aside from not being reliant on the internet (which some governments restrict), it is more clandestine and less traceable.

  • "It's pretty clearly unconstitutional," said Gregg Leslie, legal defense director at the Reporters Committee for Freedom of the Press in Alexandria, Va. "They would have to show an important need to justify these limits, and they just can't."
  • Close didn't cite any real-life examples of why the policy is needed or what problems it's addressing. She didn't know whether any media outlets had applied for permits in the last four years.
  • "The Forest Service needs to rethink any policy that subjects noncommercial photographs and recordings to a burdensome permitting process for something as simple as taking a picture with a cell phone," Wyden said. "Especially where reporters and bloggers are concerned, this policy raises troubling questions about inappropriate government limits on activity clearly protected by the First Amendment."

Lights out: The dark future of electric power - opinion - 12 May 2014 - New Scientist - 0 views

  • We tend to think of such events as occasional, inconvenient blips. But in fact they are becoming increasingly common, and will only get more frequent and severe. This is because our electricity systems are more fragile than is commonly supposed, and are getting frailer. Unless we act, blackouts will become a regular, extremely disruptive part of everyday life.
  • The vulnerability of such systems is demonstrated by the Italian blackout of 2003. The event began when a falling tree broke a power line in Switzerland; when a second tree took out another Swiss power line, connectors towards Italy tripped and several Italian power plants failed as a result. Virtually the whole country was left without power. It says something when a nation can be brought to a halt by two trees falling outside its borders.
  • We predict that blackouts will occur with greater frequency and greater severity due to trends in both electricity supply and demand. Supply will become increasingly precarious because of the depletion of fossil fuels, neglected infrastructure and the shift toward less reliable renewable energy. Demand, meanwhile, will grow because of rising populations and affluence.

  • Between 1940 and 2001, average US household electricity use rose 1300 per cent, driven largely by growing demand for air conditioning. And such demand is forecast to grow by 22 per cent in the next two decades.

    While not a green energy story, it is relevant.  The reality is that our demand for power is growing quicker than the volume of power we can produce.
