Pyrrole chemistry: Good things come in threes

A new approach leads to the long-awaited formation of rings made of three pyrroles, which could be used to produce compounds with a host of interesting properties, and explains why they have not been observed before.

'Double decoration' enhances industrial catalyst

Adding lead and calcium to an industrial catalyst dramatically improves its ability to support propylene production at very high temperatures, making it stable and active for a month.

Underwater seismometer can hear how fast a glacier moves

Scientists show that an ocean-bottom seismometer deployed close to the calving front of a glacier in Greenland can detect continuous seismic radiation from a glacier sliding, reminiscent of a slow earthquake.

New method makes generic polymers luminescent

Researchers from Hokkaido University have successfully developed a new method to give luminescent properties to generic polymers, such as polystyrene and polyethylene. The technique, which was published in the journal Angewandte ...

Corals tell Arabian Sea story of global warming

Every year, the southwesterly winds of the summer monsoon sweep down the Arabian Peninsula, pushing the surface waters of the Arabian Sea away from the coast and driving an upwelling of deep waters to the surface. This rising ...

Plant flowering in low-nitrogen soils: A mechanism revealed

Scientists from Japan, Europe and the USA have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural production.

Toward overcoming solubility issues in organic chemistry

Scientists from Hokkaido University have developed a rapid, efficient protocol for cross-coupling reactions, vastly expanding the pool of chemicals that can be used for the synthesis of useful organic compounds.

Two biodiversity refugia identified in the Eastern Bering Sea

Scientists from Hokkaido University have used species survey and climate data to identify two marine biodiversity refugia in the Eastern Bering Sea—regions where species richness, community stability and climate stability ...
