Life-shortening telomere gene discovered

PARIS: Some people carry a genetic variant is responsible for short telomeres - caps at the end of DNA that control ageing - and it could shave three or four years off their life, according to a new study.

A ligand-dependent hammerhead ribozyme switch for controlling mammalian gene expression

The possibility to externally control gene expression is of fundamental importance in both basic and applied life sciences. Although there are some techniques available to regulate expression in mammalian cells, they rely on the presence of ligand-sensing transcription factors, making it necessary to generate cell lines or organisms that stably express these regulatory factors. In recent years, mechanisms relying on direct RNA-ligand interactions for controlling gene expression have been both discovered in nature and engineered artificially. Among the latter, RNA switches relying on catalytically active RNA have been described. In principle, ligand-dependent triggering of mRNA self-cleavage should be a universal mechanism in order to control gene expression in a variety of organisms.

Second Life Tries To Backpedal On the GPL

GigsVT writes "The Second Life viewer has been available under the GPL for three years. Linden Lab, the maker of Second Life, recently released a 'third party viewer' policy that all but erases the freedoms granted under the GPL. It includes such draconian measures as 'You agree to update or delete at our request any data that you have received from Second Life or our servers and systems using a Third-Party Viewer,' 'You must not mask IP or MAC addresses' (reported to the server), 'you must have a published privacy policy explaining your practices regarding user data,' and 'You acknowledge and agree that we may require you to stop using or distributing a Third-Party Viewer for accessing Second Life if we determine that there is a violation.'"

Cancer: "Primitive" Gene Discovered Researchers Prove Cancer Gene In Ancestral Metazoan

To find the causes for cancer, biochemists and developmental biologists at the University of Innsbruck, Austria, retraced the function of an important human cancer gene 600 million years back in time. For the first time, they have identified the oncogene myc in a fresh water polyp and they have shown that this oncogene has similar biochemical functions in ancestral metazoan and in humans. The scientists published their findings in PNAS.

Second Life Gang Using Copyright To Stop Discussion Of Its Tactics?

I'll admit that the details on this one are a bit confusing and not explained well for those of us who don't use Second Life. But, reading through the (admittedly one-sided) documents pass along by Pixeleen Mistral, it sounds like a vigilante group within Second Life going by the name Second Life Justice League Unlimited, and which has avatars designed to look like trademarked super heroes, had a private wiki, which was leaked. The publication, the Second Life Herald, wrote about it, using information from the wiki... and the SLJLU has used a copyright claim to Typepad in an attempt to get the stories taken down. Seeing as the publication of the contents was part of a journalistic effort, it seems like a pretty clear case of fair use, and it's a bit upsetting that Typepad automatically sided with those making the copyright claim.

Life beyond our universe: Physicists explore the possibility of life in universes with laws different from our own

(PhysOrg.com) -- Whether life exists elsewhere in our universe is a longstanding mystery. But for some scientists, there?s another interesting question: could there be life in a universe significantly different from our own?

Male Infertility Gene Discovered by Chinese Scientists

Researchers from Shanghai Jiao Tong University's School of Medicine have discovered a male infertility gene.

Life Sciences: Fudan University, Gene Research Center publishes research in life sciences

New investigation results, 'Laminarin-mediated targeting to Dectin-1 enhances antigen-specific immune responses,' are detailed in a study published in Biochemical and Biophysical Research Communications. According to recent research published in the journal Biochemical and Biophysical Research Communications, "It has immense potential for immunotherapy and vaccination to target antigens to antigen-presenting cells (APCs). Here we described a method for delivering whole protein antigens to APCs via carbohydrate-mediated targeting of Dectin-1, which is a C-type lectin and mainly expresses on subpopulations of dendritic cells and macrophages."

Gene discovery may have profound impact

British researchers have identified a gene variant that may be linked to ageing. The discovery of the gene could allow doctors to make an early diagnosis of people who are prone to ageing more rapidly than usual, so they can prescribe courses of treatment that will allow such persons to extend their life by avoiding certain health risks and taking certain medicines.

Scientists Discover Gene Behind Pain

Scientists have discovered a gene which may help explain why some people are more sensitive to and less able to tolerate pain.

Dr Geoffrey Woods, of Cambridge University, said that discovery of a gene responsible for pain could greatly increase the ability to conquer and control it.

Artificial Life, Inc. Mandates Close Brothers Seydler Bank AG as Its Designated Sponsor in Germany

FRANKFURT, Germany, HONG KONG and LOS ANGELES, Feb. 16, 2010 (GLOBE NEWSWIRE) -- Artificial Life, Inc. (OTCBB:ALIF), a leading provider of award-winning mobile 3G technology and applications, today announced that it has mandated Close Brothers Seydler Bank AG, the German Small and Mid-Caps specialist bank, as its Designated Sponsor (market maker) for its planned upgraded listing in the Entry Standard market segment in Germany later this year. Artificial Life, Inc. shares have been traded for several years in the over-the-counter market in Germany, and the Company intends to upgrade its German trading activities to the Entry Standard segment of the Frankfurt Stock Exchange. The Company's current United States over the counter listing and trading of Artificial Life's shares in the United States will not be affected by this anticipated chang

Discovery Of Gene That Affects Susceptibility To TB And Clues To How It Works

University of Washington (UW) researchers have identified a gene involved in susceptibility and resistance to tuberculosis. This same gene, they have found, has a role in the severity of leprosy, which is caused by a related pathogen. The researchers also have learned why this gene is important for susceptibility.

Johnny Cash: LIFE's Best Photos

Nov. 21, 1969: The cover of LIFE magazine features Johnny Cash, who'd just released his "At San Quentin," his second live album recorded before inmates (the first, "At Folsom Prison," was his breakthrough).

Structureless Space Telescope Could Look For Life Around Other Stars

Goes color A big aspiration for astronomers is to identify life on planets orbiting other stars. Thanks to NASA's Kepler mission we will know about the statistical abundance of Earthlike worlds in our galaxy in just a few years. But confirming that other worlds are actually inhabited (not just inhabitable) could take decades. And, finding just one such planet won't be enough. We'll need to survey at least several nearby exo-Earths to convince ourselves we are actually seeing the biosignatures of life. Accomplishing this will be a Herculean task. Huge space telescopes are needed to harvest the feeble glow of an exo-Earth. That's because the light needs to be dissected into a spectrum that yields the chemical fingerprint of life processes. Probably nothing smaller than a 16-meter space telescope would be needed.

Tufts University, Health Sciences: Researchers develop new tool for gene delivery

Researchers at Tufts University School of Medicine and the Sackler School of Graduate Biomedical Sciences at Tufts have developed a new tool for gene therapy that significantly increases gene delivery to cells in the retina compared to other carriers and DNA alone, according to a study published in the January issue of The Journal of Gene Medicine. The tool, a peptide called PEG-POD, provides a vehicle for therapeutic genes and may help researchers develop therapies for degenerative eye disorders such as retinitis pigmentosa and age-related macular degeneration.

Gene Expression Patterns In Malaria Discovered
