Today's Science News
Automated preparation of analytical samples
Agilent Technologies' 7696 Sample Prep Workbench reduces the cost per sample because it consumes smaller amounts of chemicals and solventsMicroscope features ultra stable specimen stage for high magnification navigation
Fine specimen stage control that is needed for smooth operation at such high magnifications in order to be able to locate and maintain the regions of interestPeptides purification HPLC columns
Resolux line delivers purification solutions for very short peptides up to large chains by offering consumables in three different pore sizes
Pharmacology
Sugar in biotech drugs causes inflammation
Researchers have discovered that a kind of sugar molecule common to chimpanzees, gorillas and other mammals but not found in humans provokes a strong immune response in some people.Troubling side effects of Parkinson's medication
The standard medication used to treat Parkinson's is Levodopa, a drug that initially has major benefits but can later also produce serious side effects in the form of involuntary, jerky movements.Medications found to cause cognitive impairment of aging brain
Drugs commonly taken for a variety of common medical conditions including insomnia, allergies, or incontinence negatively affect the brain causing long term cognitive impairment in older African-Americans, according to a study.
Nanotechnology
Bee venom forms cancer-killing smart bomb
A toxic protein in bee venom, when altered, significantly improves the effectiveness liposome-encapsulated drugs or dyes, such as those already used to treat or diagnose cancer.New catalyst of platinum nanoparticles
Scientists have discovered a catalyst and catalyst-support combination that could make fuel cells more stable, conk-out free, inexpensive and more resistant to carbon monoxide poisoning.Graphene oxide gets green
A new study demonstrates an environmentally friendly way to make bulk quantities of graphene oxide, an insulating version of single-atom-thick graphene expected to find use in all kinds of material and electronic applications.
Environment
Oxygen fuels the fires of time
A team of scientists have shown that the amount of charcoal preserved in ancient peat bogs, now coal, gives a measure of how much oxygen there was in the past.New carbon dioxide emissions model
With the help of new models for a prescribed atmospheric carbon dioxide concentration, scientists from all over Europe have now calculated for the first time the extent to which the global carbon dioxide emissions must be reduced to halt global warming.U.S. response to climate change
A comprehensive national response to climate change should be informed by reliable data coordinated through climate services and a greenhouse gas monitoring and management system to provide timely information tailored to decision makers at all levels.
Biotechnology
New math speed detection of drug-resistant malaria
Researchers developed techniques to quickly identify evolution of drug resistance in strains of malaria. Their goal is to enable the medical community to react quickly to inevitable resistance.Synthetic bone graft recruits stem cells
A new study shows how particles of a ceramic called calcium phosphate have the ability to stimulate promising bone regrowth by attracting stem cells and 'growth factors' to promote healing and the integration of the grafted tissue.Why MRC said no to in vitro fertilisation
An intriguing paper published in Europe's leading reproductive medicine journal Human Reproduction reveals for the first time the reasoning behind the MRC's much-criticised decision.
Genetics
Reducing spread of oral cancers
The spread of cancer cells in the tongue may be reduced if a gene that regulates cancer cell migration can be controlled, according to new research.Variations cause high triglyceride levels in blood
A recent study has shown that it's a combination of both common and rare variants or 'misprints' in several genes that add up and put a patient at risk of developing HTG.Disease genes that followed the Silk Road identified
Scientists have identified key genes responsible for a severe inflammatory disease that has spread along the old silk trading routes from the Far East to the edge of Europe.
