Small RNA plays big role suppressing cancer

Science Daily - Thu, 02/04/2015 - 8:16pm
The micro RNA miR-22 has long been known for its ability to suppress cancer. However, questions remain about how it achieves this feat. For example, which molecules are regulating miR-22, and which are miR22 targets? Researchers have unraveled some of these relationships, identifying several interactions that directly impact liver and colon cancer.

A new breakthrough in thermoelectric materials

Science Daily - Thu, 02/04/2015 - 8:15pm
Scientists have developed a scalable production method for a state of the art alloy for the use in solid state thermoelectric devices.  This new alloy is nearly twice as efficient as existing materials and may lead to a new host of applications. Uses include refrigeration, consumer electronics, transportation as well as novel devices which have not been produced yet do to the inefficiencies of existing materials.

Antibacterial enzymes to combat drug-resistant bacterial pathogens developed

Science Daily - Thu, 02/04/2015 - 8:15pm
By engineering antibacterial enzymes, investigators are using novel strategies to target the prevalent drug-resistant bacterium Staphylococcus aureus. "Antibacterial enzymes, which kill via catalytic mechanisms, represent promising candidates in the fight against drug-resistant microbes," explained the lead researcher. "Staph infections in hospital settings are a serious problem that has gained widespread public attention, and there's an urgent need to address the threat of antibiotic resistance. Using molecular engineering, we are expanding the pool of antibacterial drug candidates and improving their performance."

Element of surprise helps babies learn

Science Daily - Thu, 02/04/2015 - 8:15pm
Cognitive psychologists have demonstrated for the first time that babies learn new things by leveraging the core information they are born with. When something surprises a baby, like an object not behaving the way a baby expects it to, the baby not only focuses on that object, but ultimately learns more about it than from a similar yet predictable object.

Deconstructing brain systems involved in memory and spatial skills

Science Daily - Thu, 02/04/2015 - 8:13pm
In work that reconciles two competing views of brain structures involved in memory and spatial perception, researchers have conducted experiments that suggest the hippocampus -- a small region in the brain's limbic system -- is dedicated largely to memory formation and not to spatial skills, such as navigation.

Widest possible photosynthesis, absorbing any color of sunlight, from oranges through near-infrared

Science Daily - Thu, 02/04/2015 - 8:13pm
A small team of chemists, having learned the secrets of light absorption from chlorophylls a and b, can now tune molecules to absorb anywhere in the solar spectrum. They are using this facility to synthesize pigments that fill gaps in the sunlight absorbed by native pigments and to push deeper into the infrared than any native pigment.

Visual Studio 2015 Can Target Linux; Android Apps Anywhere Chrome Can Run

Slashdot - Thu, 02/04/2015 - 8:00pm
jones_supa writes Phoronix has noticed that the Visual Studio 2015 product page mentions that the new IDE can target Linux out of the box. Specifically the page says "Build for iOS, Android, Windows devices, Windows Server or Linux". What this actually means is not completely certain at this point, but it certainly laces nicely with the company opening up the .NET Framework. And speaking of cross-platform software: new submitter mccrew writes Google has released a tool that lets Android apps run on any machine that can run its Chrome browser. Called Arc Welder, the tool acts as a wrapper around Android apps so they can run on Windows, OS X and Linux machines. The software expands the places that Android apps can run and might make it easier for developers to get code working on different machines.

How to Prepare for an IT Security Disaster (Video)

Slashdot - Thu, 02/04/2015 - 7:18pm
What should you do if your company's servers are hacked and your customers' credit card info or other data are stolen? Neill Feather, president of SiteLock, says you should have a plan of action tested and ready to go, the same way it's wise to hold fire drills so that everyone knows what to do in case of fire. Neill also recommends checking out the Online Trust Alliance and the many resources it makes available to businesses of all sizes whether or not they are OTA members. One document that would be a good place to start is their Data Protection & Breach Readiness Guide, which covers topics including liability and insurance considerations; basic forensics (to help catch the evildoers -- and prevent them from doing evil to you again); and even what information you should include in a letter to customers after a Target or Home Depot-type data theft. We can sum all of this up with the old saying, 'An ounce of prevention is worth a pound of cure,' but you should also know what to do if a problem happens, whether that problem is data theft, a ransomware attack or anything in between.

Ask Slashdot: Living Without Social Media In 2015?

Slashdot - Thu, 02/04/2015 - 6:32pm
An anonymous reader writes On Slashdot, we frequently write derogatory comments regarding social networking sites. We bash Facebook and the privacy implications associated with having a great deal of your life put out there for corporations to monetize. Others advocate for deleting your Facebook profile. Six months ago, I did exactly that. However, as time went on, I have fully realized social media's tacit importance to function in today's world, especially if you are busy advancing your career and making the proper connections to do so. Employers expect a LinkedIn profile that they can check and people you are meeting expect a Facebook account. I have heard that not having an account on the almighty Facebook could label you as a suspicious person. I have had employers express hesitation in hiring me (they used the term "uncomfortable") and graduate school interviewers have asked prying questions regarding some things that would normally be on a person's social media page. Others have literally recoiled in horror at the idea of someone not being on Facebook. I have found it quite difficult to even maintain a proper social life without a social media account to keep up to date with any sort of social activities (even though most of them are admittedly quite mundane). Is living without social media possible in 2015? Does social media have so much momentum that the only course of action is simply to sign up for such services to maintain normality despite the vast privacy issues associated with such sites? Have we forgotten how to function without Facebook?

Tesla's April Fool's Joke Spoofs Market Algorithms

Slashdot - Thu, 02/04/2015 - 5:50pm
Okian Warrior writes Yesterday, Tesla's twitter feed and blog announced the new "W" Model. Meaning "Watch" (as in "wristwatch"), the announcement Included a photo of a watch spouting a cumbersome "Big Ben" glued to the face and including this text: "This incredible new device from Tesla doesn't just tell the time, it also tells the date. What's more, it is infinitely adjustable, able to tell the time no matter where you are on Earth. Japan, Timbuktu, California, anywhere! This will change your life. Reality as you know it will never be the same." Clearly, this was an April fool's joke as anyone who reads more than just the headline would immediately guess. The problem is that Bloomberg's fast response team did not. The algos, on massive volume, spiked TSLA stock higher by nearly 1%.
