Columbia engineering innovative hand-held lab-on-a-chip could streamline blood testing worldwide
Columbia biomedical engineering professor develops innovative strategy for an integrated microfluidic-based diagnostic device that can perform complex laboratory assays, with such simplicity that these tests can be carried out in the most remote regions of the world.

Researchers discover the mechanism that determines cell position in the intestinal epithelium
Researchers with the Colorectal Cancer Lab at IRB Barcelona have revealed the molecular mechanisms responsible for organizing the intestinal epithelium into distinct comportments, defined by frontiers or territories.

Physics could be behind the secrets of crop-circle artists
In this month's edition of Physics World, Richard Taylor, director of the Materials Science Institute at the University of Oregon, takes a serious, objective look at a topic that critics might claim is beyond scientific understanding -- crop circles.

RUB researchers decipher the molecular basis of blue-green algae
Under normal conditions, cyanobacteria, also termed blue-green algae, build up energy reserves that allow them to survive under stress such as long periods of darkness.

Genome of CHO-K1 provides new insights into optimization of biopharmaceutical protein production
BGI, the world's largest genomics organization, and GT Life Sciences, Inc., a privately held biotechnology company that utilizes a proven metabolic modeling and experimental platform to drive the discovery and design of new products and processes for the life sciences field, announced today that their collaborative study on the genomic sequence of the Chinese hamster ovary (CHO) K1 cell line was published online in Nature Biotechnology.

National asthma genetics consortium releases first results
A new national collaboration of asthma genetics researchers has revealed a novel gene associated with the disease in African-Americans, and confirmed the significance of four gene associations reported by a European asthma genetics study.

Genome-wide study reveals 3 new susceptibility loci for adult asthma in Japanese population
Researchers at the RIKEN Center for Genomic Medicine, together with colleagues at Kyoto University, Tsukuba University, Harvard University and other medical institutions have identified three new loci associated with susceptibility to adult asthma in the Japanese population.

70 percent of 8-month-olds consume too much salt
Seventy per cent of eight-month-old babies have a salt intake higher than the recommended UK maximum level, due to being fed salty and processed foods like yeast extract, gravy, baked beans and tinned spaghetti.

CSHL scientists reveal mechanism behind 'oncogene addiction' in acute leukemia
Scientists at CSHL have laid bare the mechanism behind oncogene addiction, in mice suffering from a form of leukemia that mimics acute myelogenous leukemia (AML) in humans.

Discovery of a new magnetic order
Physicists at Forschungszentrum Juelich and the universities of Kiel and Hamburg are the first to discover a regular lattice of stable magnetic skyrmions -- radial spiral structures made up of atomic-scale spins -- on a surface instead of in bulk materials.

Physicists show that quantum ignorance is hard to expose
No-one likes a know-it-all but it turns out that a quantum know-it-all is the worst.

Dissecting the genomes of crop plants to improve breeding potential
Scientists on the Norwich Research Park, working with colleagues in China, have developed new techniques that will aid the application of genomics to breeding the improved varieties of crop needed to ensure food security in the future. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
