Trees are growing more rapidly due to climate change. This may sound like good news—after all, this means that trees are storing more carbon dioxide from the atmosphere in their wood, and hence modulating a key ingredient ...

When viruses infect phytoplankton, it can change the clouds

Microscopic plant-like organisms called phytoplankton are known to support the diversity of life in the ocean. Scientists in Israel now report that one species, Emiliania huxleyi, and a virus closely associated with it, might ...

Glacier depth affects plankton blooms off Greenland

The unusual timing of highly productive summer plankton blooms off Greenland indicates a connection between increasing amounts of meltwater and nutrients in these coastal waters. In a new study published today in the international ...

Molecular switch detects metals in the environment

An international team led by researchers from the University of Geneva (UNIGE), Switzerland, has designed a family of molecules capable of binding to metal ions present in the surrounding environment and providing an easily ...

Fishing quotas upended by nuclear DNA analysis

For decades, mitochondrial DNA analysis has been the dominant method used to make decisions about fishing quotas, culling, hunting quotas, or translocating animals from one population of a threatened species to another.

Warmer ocean, warmer winter Eurasian climate

A vigorous and continuous rise in sea surface temperature (SST) and land surface temperature has been caused by increasing greenhouse gas concentrations during the last century. Several studies have suggested that the direct ...

Scientists discover organic acid in a protoplanetary disk

An international team of scientists from Russia, Germany, Italy, the U.S. and France has discovered a relatively high concentration of formic acid in a protoplanetary disk. This is the first organic molecule found in protoplanetary ...
