Technique enables efficient gene splicing in human embryonic stem cells
A novel technique allows researchers to efficiently and precisely modify or introduce genes into the genomes of human embryonic stem cells (ESCs) and induced pluripotent stem (iPS) cells, according to Whitehead scientists. view more (2009-08-14)
Study shows transfer of heavy metals from water to fish in Huelva estuary
A team of researchers from the University of Cadiz has confirmed that zinc, copper and lead are present at high levels in the water and sediments of the Huelva estuary, and have studied how some of these heavy metals are transferred to fish. view more (2009-06-16)
Gene expression pattern could lead to improved treatment of pediatric septic shock
A consortium of researchers headed by Cincinnati Children's Hospital Medical Center has discovered a gene expression pattern that could lead to improved diagnosis and treatment of pediatric septic shock - still a serious public health problem despite today's potent antibiotics and pediatric intensive care units. view more (2007-07-27)
High-res view of zinc transport protein
How much difference can a tenth of a nanometer make? When it comes to figuring out how proteins work, an improvement in resolution of that miniscule amount can mean the difference between seeing where atoms are and understanding how they interact. view more (2009-09-14)
Chemists measure copper levels in zinc oxide nanowires
Chemists at the National Institute of Standards and Technology (NIST) have been the first to measure significant amounts of copper incorporated into zinc oxide (ZnO) nanowires during fabrication. view more (2008-02-20)
Probing a rare material spin state at NIST
A team of international physicists that includes researchers from the National Institute of Standards and Technology (NIST) has found experimental evidence of a highly sought-after type of arrangement of atomic magnetic moments, or spins, in a series of materials. view more (2007-09-17)
Emory scientists discover unique binding method for essential cellular protein ubiquitin
Researchers at Emory University School of Medicine have uncovered new information about the molecular pathway used by ubiquitin, an essential protein that helps regulate the amounts and locations of other proteins within cells. view more (2006-03-24)
Gene research gets faster thanks to Aston University team
Aston University researchers have won a BBSRC research grant worth over £300,000 to study one of the most exciting areas of science today - biomolecular interactions. The Aston research team has invented a better, more effective method of randomising genes for laboratory research. Dr Anna Hine, who is leading the research and was the primary... view more...

'Zinc Zipper' Plays Key Role In Hospital-Acquired Infections
Hospital-acquired infections that are resistant to traditional antibiotic treatment have become increasingly common in recent years, confounding health care professionals and killing thousands of Americans. view more (2008-12-05)
Metal composition hold key to identity of modern sculptures
How do you tell when, where and how a Picasso or a Matisse sculpture was cast? view more (2009-07-31)
Dietary intake of antioxidants associated with reduced risk of age-related macular degeneration
A diet with a high intake of beta carotene, vitamins C and E, and zinc is associated with a substantially reduced risk of age-related macular degeneration in elderly persons, according to a study in the December 28 issue of JAMA. view more (2005-12-29)
Zinc oxide gives green shine to new photoconductors
Photodetectors -- devices found in cell phones, digital cameras and other consumer gadgets that utilize photoconducting materials -- are a green technology in performance (converting light into electricity), but the manufacture of very powerful photodetectors needs to be improved before they can qualify for solid green status. view more (2009-03-19)
Ames Laboratory researchers rethink zinc
Try as they might, ancient alchemists could never turn lead into gold. Neither can the members of the Novel Materials group at the U.S. Department of Energy's Ames Laboratory. But these physicists do have a way with materials, and they can get them to do some pretty amazing things. view more (2007-04-18)
Cheaper LEDs from breakthrough in zinc oxide (ZnO) nanowire research, Nano Letters study says
Engineers at UC San Diego have synthesized a long-sought semiconducting material that may pave the way for an inexpensive new kind of light emitting diode (LED) that could compete with today's widely used gallium nitride LEDs, according to a new paper in the journal Nano Letters. view more (2007-01-04)
Scientists discover zinc link to a leading cause of blindness
An international research team including scientists at the University of Texas Medical Branch at Galveston (UTMB) and the Galveston-based spinoff Neurobiotex, Inc. has found high levels of zinc in deposits in the eye that are an indication of age-related macular degeneration (AMD) — the leading cause of blindness in the elderly in the... view more...

New small-scale generator produces alternating current by stretching zinc oxide wires
Researchers have developed a new type of small-scale electric power generator able to produce alternating current through the cyclical stretching and releasing of zinc oxide wires encapsulated in a flexible plastic substrate with two ends bonded. view more (2008-11-10)
Problem: Implant Infection. Solution: Nanotech Surfaces
Orthopaedic implants help millions of Americans stay active. But these medical devices are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of bacteria, a technique that can be applied to implants... view more...

Researchers warn that gastric bypass surgery may cause post-op nutrient deficiencies
Two studies by a group of researchers at Washington Hospital Center highlight potential postoperative nutritional deficiencies among patients who undergo gastric bypass surgery to treat obesity. view more (2007-10-15)
The Right Food Can Improve Fertility
Roasted red peppers, mini crab cakes and Brazil nuts can all help to increase fertility. They will all feature in a special Fertility Buffet, laid on by Dr Margaret Rayman, Director of the MSc Course in Nutritional Medicine at the University of Surrey, on 3 July 2003. A good, balanced diet rich in fruit and vegetables (at least five portions a... view more... (2003-06-30)
UCLA, Italian chemists move closer to solving Lou Gehrig's disease mystery
Chemists from UCLA and the University of Florence in Italy may have solved an important mystery about a protein that plays a key role in a particular form of amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, a progressive, fatal neurodegenerative disorder that strikes without warning. view more (2007-06-28)
