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. —> Read More Here

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. —> Read More Here

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. —> Read More Here
