Berkeley Lab Scientists See Urgent Need for Reducing Emissions

Lab experts are leading contributors to the IPCC Working Group III’s Fifth Assessment Report on climate change mitigation.

The bad news: a major transformation of our current energy supply system is needed in order to avoid a dangerous increase in global temperatures. The good news: the technologies needed to get there are mostly readily available. These are some of the main conclusions reached by experts from Lawrence Berkeley National Laboratory (Berkeley Lab) and their Working Group III co-authors on the Fifth Assessment Report of the U.N. Intergovernmental Panel on Climate Change (IPCC). (more…)

Berkeley Lab scientists image cell-to-cell connections between soil microbes

The next time your Facebook stream is filled with cat videos, think about Myxococcus xanthus.The single-cell soil bacterium also uses a social network. But forget silly distractions. M. xanthus relies on its connections to avoid getting eaten and to score its next meal.

That’s the latest insight from a team of Berkeley Lab scientists. Using several imaging techniques, they saw for the first time that M. xanthus cells are connected by a network of chain-like membranes. (more…)
