Latest and Breaking Chemistry & Physics News

NASA's Webb Telescope mirror tripod in action
(NASA/Goddard Space Flight Center) Setting up NASA's James Webb Space Telescope's secondary mirror in space will require special arms that resemble a tripod. NASA recently completed a test of the tripod to ensure it would function properly in space.

Traditional approaches and innovative techniques for subcellular fractionation from CSHLP
(Cold Spring Harbor Laboratory) 'Subcellular Fractionation' published by Cold Spring Harbor Laboratory Press provides step-by-step protocols for the extraction of subcellular components from animal tissues, yeasts, plants, and cultured cells. Each chapter focuses on a particular eukaryotic organelle, vesicle, membrane, or macromolecular complex. Strategies for breaking cells while maintaining the structural and functional integrity of the component of interest, enriching for that component based on its physical and biochemical characteristics, and monitoring and ensuring the success of the purification procedure are provided.

Lawrence Livermore researchers develop efficient method to produce nanoporous metals
(DOE/Lawrence Livermore National Laboratory) Nanoporous metals -- foam-like materials that have some degree of air vacuum in their structure -- have a wide range of applications because of their superior qualities.

UTSA immunologist Bernard Arulanandam selected as AAAS Fellow
(University of Texas at San Antonio) The American Association for the Advancement of Science has selected University of Texas at San Antonio immunologist Bernard Arulanandam as a 2014 Fellow for his distinguished contributions to the field of mucosal immunology.

Mere expectation of treatment can improve brain activity in Parkinson's patients
(University of Colorado at Boulder) Learning-related brain activity in Parkinson's patients improves as much in response to a placebo treatment as to real medication, according to a new study by researchers at the University of Colorado Boulder and Columbia University.

20,000 meteorites and counting
(Case Western Reserve University) A new book provides a history of the Antarctic Search of Meteorites program, details about thousands of specimens, what's been learned, and how researchers can obtain samples for free. The program, created by William Cassidy, ensures access to scientists and museums around the world, eliminating what was sure to be a competition for the resources.

Vegetable oil ingredient key to destroying gastric disease bacteria
(University of California - San Diego) The bacterium Helicobacter pylori is strongly associated with gastric ulcers and cancer. To combat the infection, researchers at University of California, San Diego School of Medicine and Jacobs School of Engineering developed LipoLLA, a therapeutic nanoparticle that contains linolenic acid, a component in vegetable oils. In mice, LipoLLA was safe and more effective against H. pylori infection than standard antibiotic treatments.

Physicists bind single-atom sheets with the same force geckos use to climb walls
(University of Kansas) The approach is to design synergistic materials by combining two single-atom thick sheets, for example, that act as a photovoltaic cell as well as a light-emitting diode, converting energy between electricity and radiation.

PharmaMar announces US partner Janssen files NDA for YONDELIS for soft-tissue sarcoma
(Pharmamar) Based on a phase 3 trial in which dacarbazine was used in the comparator arm, Janssen has submitted a NDA for YONDELIS (trabectedin) to the FDA for the treatment of patients with advanced soft tissue sarcoma, including liposarcoma and leiomyosarcoma, who have received prior chemotherapy including an anthracycline.

Researchers identify new ways to drain cancer's 'fuel tank'
(University of Manchester) Scientists at the University of Manchester have discovered a potential weakness in cancer's ability to return or become resistant to treatment, by targeting the 'fuel' part of stem cells which allows tumours to grow.
