First trace of differences between matter and 'ordinary' antimatter
The world around us is mainly constructed of baryons, particles composed of three quarks. Why are there no antibaryons, since just after the Big Bang, matter and antimatter came into being in exactly the same amounts? A lot points to the fact that after many decades of research, physicists are closer to the answer to this question. In the Large Hadron Collider beauty (LHCb) experiment the first trace of the differences between baryons and antibaryons has just been encountered. (2017-02-22)

Researchers unravel age-old mystery of why cells use fermentation
Wine, beer and yogurt are produced when microorganisms convert sugar into alcohol, gases or acids. But this process of fermentation -- which is used by bacteria, fungi and other fast-growing cells to generate energy in the absence of oxygen -- is a much less efficient way of generating energy for cells than aerobic respiration. So why do many organisms use this seemingly wasteful strategy to generate energy instead of aerobic respiration, even when oxygen is readily available? (2015-12-02)

How 139 countries could be powered by 100 percent wind, water, and solar energy by 2050

The work appears Aug. 23 in the journal Joule. (2017-08-23)

Flipping the electron spin
When lithium-ion batteries are charged too quickly, metallic lithium gets deposited on the anodes. This reduces battery capacity and lifespan and can even destroy the batteries. Scientists at the Technical University of Munich (TUM) and the Forschungszentrum J├╝lich have now presented a process that, for the first time ever, allows this so-called lithium plating process to be investigated directly. This puts new strategies for quick-charging strategies close at hand. (2017-12-06)
