Michael Schlesinger, a professor of atmospheric sciences at the University of Illinois at Urbana-Champaign, will participate in news conferences in New York City on May 9, and Washington, D.C., on May 10, publicizing the U.S. debut of the book "Avoiding Dangerous Climate Change."
Published by Cambridge University Press, the book builds upon scientific findings presented at the "Avoiding Dangerous Climate Change" conference held in Exeter, England, in February last year. The conference was sponsored by the United Kingdom Department of Environment, Food and Rural Affairs.
The conference brought together more than 200 scientists and political leaders from 30 nations. Major themes included key vulnerabilities of the climate system and critical thresholds, socio-economic effects, and technologies to limit greenhouse-gas emissions.
"This movement carries a tremendous amount of heat northward, and plays a vital role in maintaining the current climate," Schlesinger said. "If the thermohaline circulation shut down, the southern hemisphere would become warmer and the northern hemisphere would become colder. The heavily populated regions of eastern North America and western Europe would experience a significant shift in climate."
Two major factors affect the range of possible future temperature increases: Scientists don’t know precisely how sensitive the climate system will be to future emissions; and they don’t know exactly how much humankind will emit. People can only control one of the factors. By reducing emissions, the amount of future warming and associated impacts can be reduced.
"Recent work by five independent research teams has shown that climate sensitivity could be larger than the 4.5 degrees Celsius upper bound published by the Intergovernmental Panel on Climate Change," Schlesinger said. "In fact, climate sensitivities as high as 9 degrees Celsius are not implausible. Paralysis in near-term action to significantly reduce emissions could make mitigation nearly impossible to attain."
Two other authors and one of the book’s editors will also participate in the news conferences. The May 9 news conference will begin at noon EDT at JP Morgan-Chase corporate headquarters in Manhattan. The May 10 news conference will begin at 4 p.m. in Room 485 of the Russell Senate Office Building.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
