Single-atom gold catalysts may offer path to low-cost production of fuel and chemicals
New catalysts designed and investigated by Tufts engineering researchers and collaborators have potential to greatly reduce processing costs in future fuels like hydrogen. The catalysts are composed of a unique structure of single gold atoms bound by oxygen to sodium or potassium atoms, supported on non-reactive silica materials. They demonstrate comparable activity and stability with catalysts comprising precious metal nanoparticles on rare earth and other reducible oxide supports when used in producing highly purified hydrogen.

Another human footprint in the ocean
Human-induced changes to Earth's carbon cycle -- for example, rising atmospheric carbon dioxide and ocean acidification -- have been observed for decades. However, a study published this week in Science showed human activities, in particular industrial and agricultural processes, have also had significant impacts on the upper ocean nitrogen cycle.

Bitter food but good medicine from cucumber genetics
High-tech genomics and traditional Chinese medicine come together as researchers identify the genes responsible for the intense bitter taste of wild cucumbers. Taming this bitterness made cucumber, pumpkin and their relatives into popular foods, but the same compounds also have potential to treat cancer and diabetes.

Most American presidents destined to fade from nation's memory, study suggests
American presidents spend their time in office trying to carve out a prominent place in the nation's collective memory, but most are destined to be forgotten within 50-to-100 years of their serving as president, suggests a study on presidential name recall released today by the journal Science.

Mosquitoes and malaria: Scientists pinpoint how biting cousins have grown apart
Sixteen mosquito species have varying capabilities for transmitting malaria and adapting to new environments. Researchers sequenced their genomes to better understand the evolutionary science behind the differences. The results, published in Science, may advance understanding about the biological differences between mosquitoes that transmit malaria, and ultimately, how species might be more precisely controlled to stop transmission.

Social media data contain pitfalls for understanding human behavior
A growing number of academic researchers are mining social media data to learn about both online and offline human behavior. In recent years, studies have claimed the ability to predict everything from summer blockbusters to fluctuations in the stock market. But mounting evidence of flaws in many of these studies points to a need for researchers to be wary of serious pitfalls that arise when working with huge social media data sets.

The five-year survival rate for advanced-stage laryngeal cancer was higher than national levels in a small study at a single academic center performing a high rate of surgical therapy, including a total laryngectomy, or removal of the voice box, to treat the disease, despite a national trend toward organ preservation, according to a report published online by JAMA Otolaryngology-Head & Neck Surgery.

Fragile X study offers hope of new autism treatment
Researchers at the University of Edinburgh and McGill University have identified a chemical pathway that goes awry in the brains of Fragile X patients. A drug that targets this pathway reverses behavioral symptoms in mice and offers hope of new treatments for people with this common form of inherited autism.

OU professor and team discover first evidence of milk consumption in ancient dental plaque
Led by a University of Oklahoma professor, an international team of researchers has discovered the first evidence of milk consumption in the ancient dental calculus -- a mineralized dental plaque -- of humans in Europe and western Asia. The team found direct evidence of milk consumption preserved in human dental plaque from the Bronze Age to the present day.

Secret of tetanus toxicity offers new way to treat motor neuron disease
The way that tetanus neurotoxin enters nerve cells has been discovered by UCL scientists, who showed that this process can be blocked, offering a potential therapeutic intervention for tetanus. This newly-discovered pathway could be exploited to deliver therapies to the nervous system, opening up a whole new way to treat neurological disorders such as motor neuron disease and peripheral neuropathies.

Using social media for behavioral studies is cheap, fast, but fraught with biases
The rise of social media has seemed like a bonanza for behavioral scientists, who have eagerly tapped the social nets to quickly and cheaply gather huge amounts of data about what people are thinking and doing. But computer scientists at Carnegie Mellon University and McGill University warn that those massive datasets may be misleading.

NIAID/GSK experimental Ebola vaccine appears safe, prompts immune response
An experimental vaccine to prevent Ebola virus disease was well-tolerated and produced immune system responses in all 20 healthy adults who received it in a Phase 1 clinical trial conducted by researchers from the National Institutes of Health. The candidate vaccine, which was co-developed by the NIH's National Institute of Allergy and Infectious Diseases and GlaxoSmithKline, was tested at the NIH Clinical Center in Bethesda, Maryland.

How do our muscles work?
Scientists led by Kristina Djinovic-Carugo at the Max F. Perutz Laboratories of the University of Vienna and the Medical University of Vienna have elucidated the molecular structure and regulation of the essential muscle protein alpha-actinin. The new findings allow unprecedented insights into the protein's mode of action and its role in muscle disorders. The findings, made in collaboration with King's College London, may lead to improved treatments, and are published in the top-class journal Cell.
