Scientists have finally recovered stem cells from cloned human embryos, a longstanding goal that could lead to new treatments for such illnesses as Parkinson's disease and diabetes. A prominent expert called the work a landmark, but noted that a different, simpler technique now under development may prove more useful.
Expensive, state-of-the-art medical devices and surgeries often are thwarted by the body’s natural response to attack something in the tissue that appears foreign. Now, engineers have demonstrated in mice a way to prevent this sort of response.
New research reports that synthetic silicate nanoplatelets (also known as layered clay) can induce stem cells to become bone cells without the need of additional bone-inducing factors. Synthetic silicates are made up of simple or complex salts of silicic acids.
Purple bacteria are among Earth’s oldest organisms, and among its most efficient in turning sunlight into usable chemical energy. Now, a key to their light-harvesting prowess has been explained by scientists through a detailed structural analysis.
Medical instruments maker Harvard Bioscience Inc. said Wednesday that CEO Chane Graziano has stepped down and is retiring. President David Green will take over as interim CEO as the board starts a search for a new CEO. Graziano, 74, has been CEO of the company since March 1996, and Green has...
Scientists have advanced our understanding of brain plasticity by showing that the brain forms complex new circuits after damage, often far from the damaged site, to compensate for lost function. The study identified the exact regions of the brain that take over when a learning and memory center, known as the hippocampus, is damaged.
A drug developed by scientists at the Salk Institute for Biological Studies, known as J147, reverses memory deficits and slows Alzheimer's disease in aged mice following short-term treatment. The findings may pave the way to a new treatment for Alzheimer's disease in humans.
States should cut their threshold for drunken driving by nearly half_from .08 blood alcohol level to 0.05_matching a standard that has substantially reduced highway deaths in other countries, a U.S. safety board recommends. That's about one drink for a woman weighing less than 120 lbs., two for a...
The endothelium, the cellular layer lining the body’s blood vessels, is extremely resilient. Measuring just a few hundred nanometers in thickness, this super-tenuous structure routinely withstands blood flow, hydrostatic pressure, stretch and tissue compression to create a unique and highly dynamic barrier that maintains the organization necessary to partition tissues from the body’s circulatory system.
A surprising new report questions efforts to get Americans to sharply cut back on salt, saying getting to super-low levels may not be worth the struggle. Make no mistake: Most Americans eat way too much, not just from salt shakers but because of sodium hidden inside processed foods and restaurant...
A dozen years after a customer revolt forced Monsanto to ditch its genetically engineered potato, another company aims to resurrect high-tech spuds. This month, tuber processing giant J.R. Simplot Co. asked the U.S. government to approve five varieties of biotech potatoes. They're engineered not to develop ugly black bruises.
Agilent Technologies Inc. introduced the new AdvanceBio Peptide Mapping BioHPLC and ZORBAX RRHD 300-HILIC columns for the separation, characterization and analysis of a wide range of proteins, monoclonal antibodies, peptides and additional biologics.
Steinmeyer Inc. announced a new positioning system, ideal for liquid handling systems and medical dispensing applications.
The Thermo Scientific Smart-Vue wireless monitoring solution is an innovative system that safeguards the integrity of important laboratory storage by continuously monitoring critical parameters of laboratory equipment such as temperature, CO2 concentration and relative humidity.
