Making sense of patterns in the Twitterverse Posted: 07 Jun 2013 10:10 AM PDT If you think keeping up with what's happening via Twitter, Facebook and other social media is like drinking from a fire hose, multiply that by seven billion -- and you'll have a sense of what Court Corley wakes up to every morning. Corley has created a powerful digital system, dubbed SALSA, capable of analyzing billions of tweets and other messages in just seconds, in an effort to discover patterns and make sense of all the information.

Common genetic disease linked to father's age Posted: 07 Jun 2013 10:10 AM PDT Scientists have unlocked the mystery of why new cases of the genetic disease Noonan syndrome are so common; a mutation that causes the disease disproportionately increases a normal father's production of sperm carrying the disease trait.

Stranded orcas hold critical clues for scientists Posted: 07 Jun 2013 10:10 AM PDT The development of a standardized killer-whale necropsy system has boosted the complete data from killer-whale strandings from two percent to about 33 percent, according to a recent study.

Findings on onset of uterine fibroids provide potential for novel treatments Posted: 07 Jun 2013 10:09 AM PDT Uterine leiomyomata, or fibroids, are benign tumors that nevertheless affect the health of millions of women. They may cause, for instance, pain, bleeding and infertility. Fibroids are also the most common reason for a hysterectomy. Now, scientists in Finland have identified the molecular mechanisms underlying the onset of common leiomyomata.

Clinical sequencing technology identifies new targets in diverse cancers Posted: 07 Jun 2013 10:06 AM PDT Novel abnormalities in the FGFR gene were identified in a spectrum of cancers, and preliminary results with cancer cells harboring FGFR fusions suggested that some patients with these cancers may benefit from treatment with FGFR inhibitor drugs.

How do immune cells detect infections? Posted: 07 Jun 2013 10:05 AM PDT Researchers are using computer simulations to shed light on how immune cells may identify foreign antigens.

Whispering light hears liquids talk Posted: 07 Jun 2013 05:53 AM PDT Researchers have developed optomechanical sensors in which extremely minute forces exerted by light are used to generate and control high-frequency mechanical vibrations of microscale and nanoscale devices that will help unlock vibrational secrets of chemical and biological samples at the nanoscale.

'Long-awaited explanation' for mysterious effects in high-temperature superconductors Posted: 07 Jun 2013 05:53 AM PDT A German-French research team has constructed a new model that explains how the so-called pseudogap state forms in high-temperature superconductors. The calculations predict two coexisting electron orders. Below a certain temperature, superconductors lose their electrical resistance and can conduct electricity without loss.

Better screens made of organic light diodes: OLED brings out the shine Posted: 07 Jun 2013 05:52 AM PDT Screens made of organic light diodes promise unfathomable possibilities. Yet high production costs often prevent their widespread use. A new kind of production saves not only costs, but also improves the radiance of the OLED.

Glove shows its true colors: Identifies poisons on contact Posted: 07 Jun 2013 05:52 AM PDT Security takes top priority in laboratories and in production. In the future, employees exposed to risks will only have to put on a glove in order to receive a toxic substance warning: This textile identifies poisonous substances, and points them out immediately.

Oh brother, where art thou? Sticklebacks prefer to be with relatives Posted: 07 Jun 2013 05:52 AM PDT Many animals are able to discriminate between related and unrelated individuals but how they do so has proven remarkably difficult to understand. Researchers in Austria have investigated the issue using the three-spined stickleback and its shoaling preferences as a model system. It turns out that the fish prefer kin to unrelated conspecifics, regardless of how familiar they are with individual shoal members. The results indicate that level of familiarity does not affect the stickleback's ability to recognize kin. Recognition based on phenotype matching or innate recognition thus seems to be the overruling mechanism when it comes to choosing members of a peer group.
