Sponges may cut methylmercury contamination in marine food webs by more than 50%

Marine sponges may play an important, previously underestimated role in reducing methylmercury contamination in marine food webs. In a new modeling study, researchers at Helmholtz-Zentrum Hereon showed that sponges can significantly influence the spread of this environmental toxi

Fossil fish tooth chemistry uncovers Southern Hemisphere role in Earth's ice age shift

To understand where Earth might be headed, it's important to know where it has been. Throughout its existence, especially over the past couple of million years, Earth has experienced periodic cold and warm intervals, known as glacial and interglacial periods.

Laser pulses capture unexplored polaronic states

In an international experiment, researchers observed Jahn–Teller polarons—quasiparticles that could play an important role in future ultrafast spintronic devices. These polarons emerged within the crystal lattice of cobalt oxide that had been activated by carefully tailored laser

Warming may slow forest growth and cut carbon storage by 30%, model shows

Forests and land play an important role in absorbing carbon dioxide emissions, but current models and forecasts don't incorporate a surprising ecological discovery: Despite more available carbon, climate change and warmer temperatures are slowing forest growth.

Plankton-linked vapors could speed cloud seed formation over cold oceans

For nearly 50 years, scientists have suspected that microscopic marine plankton play a role in cloud formation over the oceans. Now, an experiment led by the University of Helsinki suggests that it may be more important than previously thought. The findings are published in the j
