Bumps on peacock spider make dark spots super-dark

A team of researchers with members from Harvard University, the University of Bonn, the University of Denmark and Yale University has identified bumps on the abdomens of male peacock spiders that make their dark-colored patches ...

Magnetic nanoparticles can 'burn' cancer cells

Unfortunately, cancer isn't simply a single disease, and some types, like pancreas, brain or liver tumours, are still difficult to treat with chemotherapy, radiation therapy or surgery, leading to low survival rates for patients. ...

Coffee-based colloids for direct solar absorption

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal ...

New approach facilitates spectroscopy on individual molecules

While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich (TUM) provides precise information about the interaction of individual ...

A water-splitting catalyst unlike any other

Electricity can be generated by renewable sources such as sunlight and wind, then used to split water, which makes hydrogen as a fuel for emerging energy devices such as fuel cells. Because hydrogen is a clean fuel, researchers ...

Superior noise control using graphene

Noise is a dangerous worldwide environmental pollutant: at normal levels found in cities it can induce annoyance, stress and fluctuations in sleep patterns which in turn increase the risk of type-2 diabetes, arterial hypertension, ...
