Methane emissions spike: Is there one main culprit?

The level of methane in the atmosphere has risen dramatically in the last decade—and climate scientists are worried. Although there's still roughly 60 times less of it floating around than carbon dioxide, the gas heats ...

Synchronization of ice cores using volcanic ash layers

Thin, brownish layers of a thickness of about a millimeter or two are sometimes observed in the whitish/transparent ice cores. These brown layers consist of material originating from volcanic eruptions.

Fingerprint spectroscopy within a millisecond

To guarantee high quality pharmaceuticals, manufacturers need not only to control the purity and concentration of their own products, but also those of their suppliers. Researchers at the Fraunhofer Institute for Applied ...

Fingerprints, revisited

For more than a century, forensic scientists have linked criminals to crime scenes through the distinctive loops and whorls on their fingertips. But now, researchers are moving beyond simple pattern comparisons to glean more ...

Artificial intelligence for obtaining chemical fingerprints

Researchers at the Universities of Vienna and Göttingen have succeeded in developing a method for predicting molecular infrared spectra based on artificial intelligence. These chemical "fingerprints" could only be simulated ...

Forensic chemical analysis of wood could stop illegal logging

Tackling the problem of illegal logging is particularly challenging as it is often nearly impossible to tell where a piece of wood came from. Now, researchers in Oregon, USA, have developed a technique that uses the chemical ...

Optical fingerprint can reveal pollutants in the air

More efficient sensors are needed to be able to detect environmental pollution. Researchers at Chalmers University of Technology have proposed a new, sophisticated method of detecting molecules with sensors based on ultra-thin ...

Sailors leave ancient 'fingerprints' across Polynesia

A long-standing debate on the colonisation process of Oceania has been put to rest with new research finding Polynesia was deliberately settled in one of the greatest maritime migrations in human history.
