Sketchable, Stretchable Circuits (acs.org) 34

JMarshall writes: A new, elastic silver ink allows stretchy circuits to be drawn using a regular pen. Unlike previous inks, which have been made with silver nanoparticles and are prone to clog pens over time, this ink begins as a silver salt mixed with adhesive rubber (abstract). After writing, the ink is brushed with a formaldehyde and sodium hydroxide solution that reduces the silver ions to conductive silver nanoparticles. Researchers strung 14 LED lights together using the ink. The lights stayed lit even through stretching and bending the rubber sheet the circuit was drawn on.

Submission + - Google Is Testing Signing Into Accounts Using Your Phone, No Password Required

An anonymous reader writes: Google’s battle against poor passwords is continuing. The company is now testing a new Google Account option that lets users login using their phone, skipping the part where you have to enter your password. The feature uses your phone to authenticate your identity by bringing up a notification that allows you to grant or deny access to your account. “We’ve invited a small group of users to help test a new way to sign-in to their Google accounts, no password required,” a Google spokesperson told VentureBeat. “‘Pizza’, ‘password’, and ‘123456’ — your days are numbered.”

The Big Diabetes Lie writes: Research centers have been searching for a solution that can end miseries of diabetes sufferers. Do you really believe that they have found no cure these years? Why are we still following studies that are decades old? In all these years there have been millions of people who were diagnosed and died due to this disease.

Submission + - Cops Fighting Mandatory Drug Tests

An anonymous reader writes: A new controversy has been sparked by a recent event in Pittsburgh which, in itself, is not in any way remarkable. When a car chase involving city police and a suspect ended in a crash, officers at the scene were required to undergo drug and alcohol testing.

Considering this is a common practice when a member of the general public is involved in a car accident, you wouldn’t think there would be much to cause an uproar. However, the police union has issued a complaint about the city’s drug testing policy because an officer who participated in the chase, but was not actually directly involved in the accident, was also ordered to submit to testing.
Believe it or not, instant drug tests which can deliver results in minutes are available now to be used in situations such as this one. And what is really interesting is that they can test for up to 12 different sub-stances, rather than the 5 most common ones that are normally screened for.

This is part of the reason that there is now some push back from the police union about Pittsburgh’s drug testing policy.

NASA Has Suspended Its Next Mission To Mars (sciencemag.org) 46

sciencehabit writes: NASA has suspended its next mission to Mars after problems with a French-built seismological instrument could not be fixed in time for the scheduled launch. The mission, a lander called InSight that was to listen for tremors on Mars as a way of understanding the planet's interior, will not launch in March 2016, the agency said today. NASA has not announced a new launch date, but because of the relative orbits of Mars and Earth, the agency will have to wait at least 26 months before it can try to launch again. The troublesome instrument is called the Seismic Experiment for Interior Structure; the Max Planck Institute, one of the instrument's developers, has a nice page outlining SEIS's construction and function.

Submission + - The science behind the Paris climate accords

Lasrick writes: The Bulletin of the Atomic Scientists offers a pretty thorough run-down of the pros and cons of the Paris climate accords. In a truly fascinating article, William Sweet examines not only the political machinations behind the agreement but much of what the agreement entails and how it got there after 21 years of COP meetings. In an audio recording of a teleconference briefing given to the Bulletin's Science and Security Board and other leading scientists and policy makers, Sivan Kartha and Richard Somerville (both on the S & S Board) give riveting explanations of the two weeks at Paris and what was accomplished (and not accomplished). The Question/Answer session is just as good as the presentations by Kartha and Somerville, as various leading minds in the field ask questions and offer additional information. Great stuff.

Submission + - SPAM: Disrupting Telecommunications in 2020 by Force

davejohnsen writes:

With the growth of telecommunications, a lot of good things have been said for its upcoming growth and development. Almost all people are predicting a big dependency on telecommunications using mobile, laptop or tablet media. Not only are the users increasing each day but the providers as well.

Thousands of telecommunication networks exist and is continuously emerging finding the market of the industry a good investment. There are the famous AT&T in America and in Asia, Indosat, XL Axiata, a subsidiary of Axis Capital Group of telecommunication networks based in Malaysia and has expanded to Jakarta and PT Telekomsel are the major networks which compete in the 4th most populous country of the world, Indonesia.

However though, is there anyone who is concerned of the factors that may impact the quality of telecommunication in, let’s say, five years from now? Possible changes may be as follows:

1. Content
With the demand and complaints of connection and the competition so fierce, things become cheaper and cheaper. The law of supply and demand will be materialized in this situation. The cost of providing such a service keeps falling, and competition means that the price keeps getting smaller and smaller in a strong, negative feedback loop. Connectivity is capturing an ever-smaller proportion of the information value chain, while content, service, and product deliverers capture ever-more.

2. Traffic
A new coined word, Thingification or the internet of things will be a big issue in the near future. A lot of data will be uploaded online with a lot of devices used. If we are only using terabyte hard drives for now, expect to use a device that can cater a million gigabyte file. The upswing of all of these devices will be an astronomical growth in data volumes; we will quickly push through Exabyte volumes and enter the world of zettabytes per year.

3. Wireless-ness
Global growth of mobile connectivity is far outpacing hardline connectivity. This makes sense, as most growth is occurring in the developing world and amongst poorer populations. Such consumers may not even own a home, let alone a FiOS connection. For these people, mobile are cheaper, more convenient, and more useful, even when landline connectivity is an option.

4. Threat
Since there are a lot of essential data in the net and a lot of highly confidential information are stored in a cloud, the demand for safer use of internet and protection against hackers and scammers will surely increase. Customers will begin to expect, and then demand more proactive protection from the entire internet value chain, and carriers will be expected to support these expectations with a range of technical and operational innovations. The desire for greater security may be a boon for carriers, if they embrace the need.

Bats' White-Nose Syndrome May Be Cured 89

New submitter alabamatoy writes: Several news outlets are reporting that a common bacteria may be proving successful in curing "white-nose syndrome" which has been decimating the bat populations across North America. A new treatment using a common bacterium was developed in Missouri by Forest Service scientists Sybill Amelon and Dan Lindner, and Chris Cornelison of Georgia State University. The Nature Conservancy reports: "On May 20, 2015, Scientists and conservationists gathered outside the historic Mark Twain Cave Complex in Hannibal, Missouri, to release back into the wild some of the first bats successfully treated for deadly White-Nose Syndrome." Bats are a key player in the environment, keeping insect populations under control, especially mosquitoes.

Submission + - Exploring The Diabetes-Alzehimer Connection

BarbaraHudson writes: From the I-can't-remember-where-I-left-my-insulin dept

The Australian Business Review, report on two studies, one on mice, the other on humans, look at how diabetes may be a risk factor for developing Alzheimers

In the Washington University study of mice whose brains were genetically engineered to resemble the brains of humans with Alzheimer’s disease, high doses of sugar over several hours resulted in significantly increased levels of amyloid beta in brain cells. The study also found that older mice with existing amyloid build-up in their brains experienced even greater production of amyloid beta.

The data suggest that blood sugar plays a role in managing amyloid production, with sugar creating excitability in the brain’s neurons that leads to more amyloid being produced

A separate University of Pittsburgh study of roughly 180 middle-aged people found that Type 1 diabetics had significantly more brain lesions called white matter hyperintensities than people without diabetes, and performed more poorly on cognitive function tests.

Many researchers believe that Type 2 diabetics are more vulnerable to developing Alzheimer’s disease because they suffer from insulin resistance, where cells are unable to use insulin effectively, leading to an accumulation of sugar in the blood. It is thought that the brain also develops insulin resistance, depriving the brain of nutrients from sugar.

jfruh writes: Point-of-sale software has meant that in many cases where once you'd have seen a cash register, you now see a general-purpose PC running point-of-sale (PoS) software. Unfortunately, those PCs have all the usual vulnerabilities, and when you run software on it that processes credit card payments, they become a tempting target for hackers. One of the latest attacks on PoS software comes in the form of malicious Word macros downloaded from spam emails.

Leaked Document Shows Europe Would Fight UK Plans To Block Porn 253

Mark Wilson writes: Before the UK elections earlier in the month, David Cameron spoke about his desire to clean up the internet. Pulling — as he is wont to do — on parental heartstrings, he suggested that access to porn on computers and mobiles should be blocked by default unless users specifically requested access to it. This opt-in system was mentioned again in the run-up to the election as Secretary of State for Culture, Media and Sport, Sajid Javid assured peopled that the party "will age restrict online porn". But it's not quite that simple. There is the small problem of Europe. A leaked EU Council document shows that plans are afoot to stop Cameron's plans in its tracks — and with the UK on the verge of trying to debate a better deal for itself within Europe, the Prime Minister is not in a particularly strong position for negotiating on the issue. Cameron has a fight on his hands, it seems, if he wants to deliver on his promise that "we need to protect our children from hardcore pornography". Documents seen by The Sunday Times reveal that the EU could make it illegal for ISPs and mobile companies to automatically block access to obscene material. Rather than implementing a default block on pornography, the Council of the European Union believes that users should opt in to web filtering and be able to opt out again at any time; this is precisely the opposite to the way Cameron would like things to work.

Submission + - DNA on Pizza Crust Leads to Quadruple Murder Suspect

HughPickens.com writes: In a case straight out of CSI, CNN reports that police are searching for the man suspected in the gruesome slayings of the Savopoulos family and their housekeeper, after his DNA was purportedly found on a pizza crust at the scene of the quadruple murders. They discovered his DNA on the crust of a Domino's pizza — one of two delivered to the Savopoulos home May 14 as the family was held hostage inside — a source familiar with the investigation said. The pizza apparently was paid for with cash left in an envelope on the porch. The next morning, Savvas Savopoulos’s personal assistant dropped off a package containing $40,000 in cash at the home, according to the officials and police documents.

The bodies of Savopoulos, along with his wife, Amy, their 10-year-old son Philip and the family's housekeeper, Veralicia Figueroa, were discovered the afternoon of May 14 after firefighters responded to reports of a fire. D.C. Police Chief Cathy Lanier says the killings are likely not a random crime and police have issued an arrest warrant for the 34-year-old Daron Dylon Wint, who is described as 5’7 and 155 lbs and might also go by the name “Steffon.” Wint apparently used to work at American Iron Works, where Savvas Savopoulos was CEO and president. The neighborhood is home to numerous embassies and diplomatic mansions as well as the official residence of Vice President Joe Biden and his wife. "Right now you have just about every law enforcement officer across the country aware of his open warrant and are looking for him," says Lanier. "I think even his family has made pleas for him to turn himself in."

Submission + - Tiny robots climb walls carrying more than 100 times their weight (newscientist.com)

schwit1 writes: Mighty things come in small packages. The little robots in this video can haul things that weigh over 100 times more than themselves.

The super-strong bots — built by mechanical engineers at Stanford — will be presented next month at the International Conference on Robotics and Automation in Seattle, Washington.

The secret is in the adhesives on the robots' feet. Their design is inspired by geckos, which have climbing skills that are legendary in the animal kingdom. The adhesives are covered in minute rubber spikes that grip firmly onto the wall as the robot climbs. When pressure is applied, the spikes bend, increasing their surface area and thus their stickiness. When the robot picks its foot back up, the spikes straighten out again and detach easily.
