Reaction rate of many molecules depends on their shape

Most molecules occur in several shapes, which may behave very differently. Using a sorting machine for molecules, a German–Swiss research team can now for the first time directly measure the various reaction rates of different ...

Odor suppression causes bad wine smell

(Phys.org) —A bad, musty smell sometimes ruins a bottle of corked wine. Since the 1990s, researchers have known that this unpleasant odor comes from the chemical 2,4,6-trichloroanisole (TCA), which forms when a fungus that ...

Existence of new element confirmed

Remember the periodic table from chemistry class in school? Researchers from Lund University in Sweden have presented fresh evidence that confirms the existence of a previously unknown chemical element. The new, super-heavy ...

Social robots see smell

"The thing that's been missing in robotics is a sense of smell," said biology professor Joseph Ayers.

Detection of single photons via quantum entanglement

Almost 200 years ago, Bavarian physicist Joseph von Fraunhofer discovered dark lines in the sun's spectrum. It was later discovered that these spectral lines can be used to infer the chemical composition and temperature of ...

How gold nanoparticles can help fight ovarian cancer

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why, and determined how to make the nanoparticles effective ...

Creating time crystals with a rotating ion ring

(Phys.org) —There has been a lot of talk recently about the possibility of building what has come to be known as a time crystal. In February 2012, Frank Wilczek originally proposed the idea that under certain conditions, ...
