Blowing in the wind: Cassini helps with dune whodunit on Saturn's moon Titan Posted: 31 Jul 2010 11:00 AM PDT The answer to the mystery of dune patterns on Saturn's moon Titan did turn out to be blowing in the wind. It just wasn't from the direction many scientists expected.

New cellular 'armor' developed to prevent infection by AIDS virus Posted: 31 Jul 2010 11:00 AM PDT Researchers have developed a novel method of attack against the AIDS virus that involves creating a prevention system, i.e. an "armor" in the cells that are likely to be infected and thus impede the virus from accessing them and starting to act on their immunological system.

Decontaminating dangerous drywall Posted: 31 Jul 2010 11:00 AM PDT A nanomaterial originally developed to fight toxic waste is now helping reduce debilitating fumes in homes with corrosive drywall.

Oral contraceptives and hormone replacement therapy may protect women against brain aneurysms, study finds Posted: 31 Jul 2010 11:00 AM PDT Results from a new study suggest that oral contraceptives and hormone replacement therapy may yield additional benefit of protecting against the formation and rupture of brain aneurysms in women.

Some like it hot: How to heat a 'nano bathtub' Posted: 31 Jul 2010 11:00 AM PDT Researchers have demonstrated the use of infrared laser light to quickly and precisely heat the water in "nano bathtubs" -- tiny sample containers -- for microscopy studies of the biochemistry of single molecules and nanoparticles.

Male modesty not appreciated by female or male interviewers, study suggests Posted: 31 Jul 2010 11:00 AM PDT A researcher who explored the consequences for men (and women) when they acted modestly in job interviews found that "modest" males were less liked, a sign of social backlash. Modesty was viewed as a sign of weakness, a low-status character trait for males that could adversely affect their employability or earnings potential. Modesty in women, however, was not viewed negatively nor was it linked to status.

Breaking the language barrier: Language translation devices for US troops tested Posted: 31 Jul 2010 05:00 AM PDT In recent tests evoking visions of the universal translator on "Star Trek," researchers evaluated three two-way, real-time, voice-translation devices designed to improve communications between the US military and non-English speakers in foreign countries.

Research of cell movements in developing frogs reveals new twists in human genetic disease Posted: 31 Jul 2010 05:00 AM PDT Mutations in a gene known as "Fritz" may be responsible for causing human genetic disorders such as Bardet-Biedl syndrome, developmental biologists, human geneticists and cell biologists have found.

From the heart: How cells divide to form different but related muscle groups Posted: 31 Jul 2010 05:00 AM PDT Using the model organism Ciona intestinalis, commonly known as the sea squirt, researchers have uncovered the origins of the second heart field in vertebrates.

Diet and alcohol alter epigenetics of breast cancer, study suggests Posted: 31 Jul 2010 05:00 AM PDT Researchers have shown that the epigenetic profiles of breast tumors are related to patient diet and alcohol use as well as tumor size.

Unexpected viral 'fossils' found in vertebrate genomes Posted: 30 Jul 2010 11:00 AM PDT Over millions of years, retroviruses, which insert their genetic material into the host genome as part of their replication, have left behind bits of their genetic material in vertebrate genomes. In a recent study, a team of researchers found that human and other vertebrate genomes also contain many ancient sequences from Ebola/Marburgviruses and Bornaviruses -- two deadly virus families.

Plant compound resveratrol shown to suppresses inflammation, free radicals in humans Posted: 30 Jul 2010 11:00 AM PDT Resveratrol, a popular plant extract shown to prolong life in yeast and lower animals due to its anti-inflammatory and antioxidant properties, appears also to suppress inflammation in humans, based on results from the first prospective human trial of the extract.

Snake venom studies yield insights for development of therapies for heart disease and cancer Posted: 30 Jul 2010 11:00 AM PDT Researchers seeking to learn more about stroke by studying how the body responds to toxins in snake venom are this week releasing new findings that they hope will aid in the development of therapies for heart disease and, surprisingly, cancer.

Researchers find new translocation; weak spots in DNA lead to genetic disease Posted: 30 Jul 2010 11:00 AM PDT Pediatric researchers continue to discover recurrent translocations -- places in which two chromosomes exchange pieces of themselves, and can lead to genetic disease and disability. Originating in locations where DNA strands are prone to bending and breaking, this translocation between chromosomes 8 and 22 strengthens the possibility that unstable spots in the genome may reflect a general mechanism lurking in the structure of DNA.

How not to blow up a molecule Posted: 30 Jul 2010 11:00 AM PDT Can single-shot imaging with femtosecond x-ray pulses from powerful new free electron lasers really work, or will the beam damage the sample too quickly? Pulse length is the key. A new study reveals that "frustrated absorption" explains why ultrashort pulses, even if their peak power is greater, do less damage to molecules than longer pulses.

Brain potentials reveal spectator effect Posted: 30 Jul 2010 11:00 AM PDT The neurological responses caused by observing somebody else playing a game have been uncovered. Researchers found differing responses for neutral observers, compared to those who wished the player to fail and those who wanted to see the player succeed.

Reality TV, cosmetic surgey linked, says researcher Posted: 29 Jul 2010 09:00 PM PDT Research suggests that teens fond of reality TV programs are more likely to join the millions who go under the knife each year. For bodies -- and minds -- still in development, these drastic decisions could have implications way after prom.

Reading terrorists minds about imminent attack: Brain waves correlate to guilty knowledge in mock terrorism scenarios Posted: 29 Jul 2010 09:00 PM PDT Imagine technology that allows you to get inside the mind of a terrorist to know how, when and where the next attack will occur. That may not be as far-fetched as it sounds. Northwestern brain wave research suggests that if the lab test had been employed in the real world with the same type of outcome, law enforcement officials ultimately may be able to confirm details about an attack that emerges from terrorist chatter.

Body of evidence: New fast, reliable method to detect gravesoil Posted: 29 Jul 2010 09:00 PM PDT Finding bodies buried by someone who wanted them to stay undiscovered can be difficult. However a new technique can reliably detect biochemical changes in a decomposing cadaver.

Nano 'pin art': Arrays are step toward mass production of nanowires Posted: 29 Jul 2010 09:00 PM PDT Researchers have cultivated many thousands of nanocrystals in what looks like a pinscreen or "pin art" on silicon, a step toward reliable mass production of semiconductor nanowires for millionths-of-a-meter-scale devices such as sensors and lasers.

Emerging E. coli strain causes many antimicrobial-resistant infections in US Posted: 29 Jul 2010 09:00 PM PDT A new, drug-resistant strain of E. coli is causing serious disease, according to a new study. The new strain, ST131, was a major cause of serious antimicrobial-resistant E. coli infections in the United States in 2007, researchers found. This strain has been reported in multiple countries and encountered all over the United States.

Kinked nanopores slow DNA passage for easier sequencing Posted: 29 Jul 2010 09:00 PM PDT In an innovation critical to improved DNA sequencing, a markedly slower transmission of DNA through nanopores has been achieved.
