Best marketing for renewable energies

Transmission system operators must assess precisely the supply of electricity from renewable energies for the next day in order to market this electricity on the European Power Exchange as effectively as possible. The sharply fluctuating supply of solar and wind energy makes reliable forecasts even more difficult. For this reason, Fraunhofer researchers, working jointly with TenneT TSO GmbH,...

BIND presents late-breaker clinical data at AACR on BIND-014's promising antitumor effects

Data from an ongoing Phase 1 clinical study of BIND-014, the first targeted and programmable Accurin nanomedicine to reach the clinic, demonstrated safety and tolerability, and showed evidence of anti-tumor activity in patients with solid tumor cancers. BIND-014 demonstrated partial response or stable disease in this heavily pretreated patient population with durable responses of up to six...

Carbon nanotubes can double growth of cell cultures important in industry

A dose of carbon nanotubes more than doubles the growth rate of plant cell cultures -- workhorses in the production of everything from lifesaving medications to sweeteners to dyes and perfumes -- researchers are reporting. Their study, the first to show that carbon nanotubes boost plant cell division and growth, appears in the journal ACS Nano.

Community-onset Clostridium difficile linked to higher risk of surgery

Patients whose symptoms of Clostridium difficile infection start outside of the hospital setting have a higher risk of colectomy due to severe infection, according to a large multicenter study funded by the Centers for Disease Control and Prevention and published in Infection Control and Hospital Epidemiology, the journal of the Society for Healthcare Epidemiology of America.

Cone snail venom controls pain

Components of the venom from marine cone snails can block the transmission of signals between nerve cells in minute quantities. This makes them potentially suitable for use as a novel analgesic. Researchers from the universities of Bonn and Jena, the Technical University of Darmstadt and the Leibniz Institute for Age Research in Jena have now identified the structure and action of various forms of...

Defying conventional wisdom, water can float on oil

Defying thousands of years of conventional wisdom, scientists are reporting that it is possible for water to float on oil, a discovery they say has important potential applications in cleaning up oil spills that threaten seashores and fisheries. Their report appears in ACS' journal Langmuir.

Disarming disease-causing bacteria

Scientists could produce new antibacterial treatments by disarming the molecular pumps bacteria use to bring disease-causing molecules in contact with animals and humans.

DNA sequencing consortium unveils patterns of mutations in autism

An autism sequencing consortium led by researchers from the Broad Institute, Massachusetts General Hospital, and six other organizations has searched for autism-related mutations in the fraction of the human genome that codes for proteins. The researchers sequenced this region, known as the "exome," in 175 autism patients and their unaffected parents. Their results suggest modest roles for...

Drawing connections between food webs

Researchers from Northwestern University, with partners from New Zealand and Spain, have discovered universal truths about species' roles in food webs. The findings could open doors to increasingly global approaches in conservation.

Drug use in 50- to 64-year-olds has increased 10-fold in England since 1993

New research published today in the journal Age and Aging has found that the lifetime use of cannabis, amphetamine, cocaine and LSD in 50- to 64-year-olds has significantly increased since 1993 and is much higher than lifetime use in adults aged over 65. The study also found that drug use in inner London was higher than the overall UK average.

Enzyme in saliva helps regulate blood glucose

Scientists from the Monell Center report that blood glucose levels following starch ingestion are influenced by genetically-determined differences in salivary amylase, an oral enzyme that breaks down dietary starches. Specifically, higher salivary amylase activity is related to lower blood glucose. The findings suggest that salivary amylase may contribute significantly to overall metabolic status.

Facilitating the work of forensic scientists

The University of the Basque Country's METABOLOMIPs group develops analytical methods to help characterize different types of substances, and focuses on the forensic sciences, in particular. For example, they have just developed a methodology for detecting gunshot residues which comes up with the results in record time, and thanks to this they have had a paper published in Analytical Chemistry,...

Fasting for Lent forces hyenas to change diet

Many Christians give up certain foods for Lent, however ecologists have discovered these changes in human diet have a dramatic impact on the diet of wild animals. In Ethiopia, members of the Orthodox Tewahedo Church stop eating meat and dairy products during a 55-day fast before Easter. As a result, spotted hyenas too change their eating habits, new research in the British Ecological Society's...

First targeted and programmable nanomedicine to show clinical antitumor effects published

BIND Biosciences published preclinical and clinical data in Science Translational Medicine showing promising effects in solid tumors and successful clinical translation of BIND-014, the first targeted and programmed nanomedicine to enter human clinical studies. The paper describes BIND-014's ability to concentrate in tumors demonstrating efficacy, safety and pharmacological properties that are...
