Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

A unique rover-based life detection system developed by Carnegie Mellon University scientists has found signs of life in Chile's Atacama Desert, according to results being presented at the 36th Lunar and Planetary Science Conference March 14-18 in Houston. This marks the first time a rover-based automated technology has been used to identify life in this harsh region, which serves as a test bed f...

Disease progression model of pancreatic cancer developed by Penn researchers

Building on previous work, researchers at the University of Pennsylvania School of Medicine have developed an animal model of pancreatic cancer that closely mimics disease progression in humans. From this, they hope to develop new treatments for this deadly disease. Advanced pancreatic cancer is among the most lethal of cancers, with a one-year survival rate after chemotherapy of only 17 to 28 pe...

Affymetrix Launches New Globin-Reduction Kits and Protocol Developed with PreAnalytiX

Affymetrix Inc. (Nasdaq: AFFX), announced today the launch of the new GeneChip(R) Globin-Reduction kits and associated protocol developed in conjunction with PreAnalytiX -- a joint venture between QIAGEN N.V. (Nasdaq: QGEN; Frankfurt, Prime Standard: QIA) and BD (Becton, Dickinson and Company). The new kits optimize the PreAnalytiX PAXgene(TM) Blood RNA System for use with Affymetrix GeneChip tec...

New HIV drug candidate developed in Sweden

Anthrax test, developed by army and CDC, receives FDA approval

A method for identifying Bacillus anthracis, the causative agent of anthrax, has been cleared for diagnostic use by the U.S. Food and Drug Administration (FDA). The test, known as the Gamma Phage Assay, was modified by scientists at the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) to improve its performance and reliability when used with clinical specimens. The original...

Scientists discover that three molecules may be developed into new Alzheimer's drugs

A team of scientists has discovered three molecules –?from a search of 58,000 compounds –?that appear to inhibit a key perpetrator of Alzheimer's disease. . .. Ken Kosik, co-director of the Neuroscience Research Institute at the University of California, Santa Barbara, headed the effort to find these molecules. The results of the study are published in the July issue of...

Portable cocaine sensor developed at UC Santa Barbara

A real-time sensor for detecting cocaine –?made with inexpensive, off-the-shelf electronics –?has been developed by a team of researchers at the University of California, Santa Barbara. Two local high school students and a Nobel laureate participated in the discovery. The potential applications of the sensor are far-reaching and include bioterrorism detection and important medical uses. . The hig...

Carbon nanotubes that detect disease-causing mutations developed by Pitt researcher

University of Pittsburgh researcher Alexander Star and colleagues at California-based company Nanomix, Inc., have developed devices made of carbon nanotubes that can find mutations in genes causing hereditary diseases, they report in the Jan. 16 issue of the journal Proceedings of the National Academy of Science. This method is less expensive and takes less time than conventional techniques. . Ca...

Potential vaccine developed for deadly leishmaniasis disease

Development of a fundamentally new "candidate," or potential, vaccine for visceral leishmaniasis, a parasitic disease that kills about 60,000 people annually, is reported in the current issue of . Despite a major research thrust by the World Health Organization (WHO), no effective vaccine exists for the visceral, or internal, form of leishmaniasis. A milder form of...

Tool developed to silence genes in specific tissues using RNAi

Researchers at The University of Texas M. D. Anderson Cancer Center say they have jumped a significant hurdle in the use of RNA interference (RNAi), believed by many to be the ultimate tool to both decode the function of individual genes in the human genome and to treat disease. . .. Previously reported approaches to achieve this were either technically cumbersom...

New strategy developed to combat West Nile Virus

The spread of West Nile Virus appears to be triggered by a complex interaction of mosquitoes, nesting birds and specific weather patterns, scientists say, which leads to "amplification" of the virus within mosquito populations. . .. .. Many early hydrologic m...

Faster, more accurate tuberculosis test developed

Researchers from the Johns Hopkins Bloomberg School of Public Health, the Imperial College London, Universidad Peruana Cayetano Heredia, in Lima, Peru, and other institutions have developed a simple and rapid new tuberculosis (TB) test. The test, called microscopic-observation drug-susceptibility or MODS, is more sensitive, faster and cheaper to perform than current culture-based tests. The study...

Resistance to anti-HIV drugs in Uganda developed due to drug supply problems

Some HIV-infected patients in Uganda who self-paid for their antiretroviral medications experienced interruptions in drug supply due to either financial demands or supply logistical disruptions. These treatment interruptions led to the development of resistance to antiretroviral medications in patients. . .. "We have found the concern is not about the occasional missed dose—most of the patients...

New antibacterials being developed to tackle MRSA superbug

A novel antibacterial medicine that kills the superbug MRSA is being developed under a new scheme launched by the Wellcome Trust. The Seeding Drug Discovery initiative is aimed at catalysing the development of new drugs in areas of unmet need. . .. The bacterium Staphylococcus aureus can infect wounds, including those resulting from m...

Scientists develope a new model of artificial canine skin

Researchers at UNIVET, a spin-off of the Universitat Autònoma de Barcelona, in cooperation with the animal nutrition company Affinity Petcare, have developed an artificial cellular model which faithfully reproduces the characteristics of dog’s skin and which will allow, therefore, the carrying out of various lines of research related to skin biology and pathology without the need to use live anim...

Novel system developed to turn data into real-time, interactive 3-D images

Seeing is believing, especially in medicine. From magnetic resonance imaging (MRI) to computed tomography (CT) scan, images of the body’s tissues and organs have become the primary tools physicians use to diagnose disease and make recommendations for effective treatment. . New, innovative data display technology developed at Kent State University will provide doctors with a dramatically improve...
