Dendrites are the destructive by-products of the cycle of charging and discharging lithium ion batteries. These tiny deposits form between the battery's anode and cathode, building up over time. Inevitably, they diminish battery life. More problematic is their risk of causing the battery to burst into flames. In the quest for safer and longer lasting batteries—especially for electric cars, trucks, and planes—researchers continue to explore methods to suppress the formation of dendrites.

Short-term moisture removal can eliminate downy mildew of spinach
Downy mildew is the biggest threat to spinach production around the world. While the pathogen has a short life cycle (approximately a week), it can produce millions of spores during the spinach growing season. Overhead sprinkler irrigation systems and dew formation on cool nights leads to more moisture, which enables these spores to infect the spinach.

Building European cities with wood would sequester and store half of cement industry's current carbon emissions
Buildings create a whopping one-third of global greenhouse gas emissions—that's about 10 times more than air traffic worldwide. In Europe alone, about 190 million square meters of housing space are built each year, mainly in the cities, and the amount is growing quickly at the rate of nearly 1% a year.

Researchers achieve fused silica with high damage threshold by combing chemical etching and laser polishing
Laser damage in fused silica, particularly ultraviolet laser damage, is still a key problem limiting the development of high-power laser systems. The traditional processing method of fused silica goes through the processes of grinding and chemical mechanical polishing (CMP). This method is time-consuming to achieve an ultra-smooth surface, and is easy to cause surface and sub-surface defects, resulting in a significant reduction in the surface damage threshold of the fused silica.

The efficiency of migratory birds' flight formations
Migratory birds flying south provide an impressive example of cooperative behavior that saves power and energy. In the past, it was impossible for scientists to study this phenomenon in a natural environment. Researchers who guided young northern bald ibises to their wintering grounds have now succeeded for the first time in obtaining a comprehensive data set. A better understanding of this behavior is also of fundamental importance in respect of climate change.

Researchers discover mechanism that allows non-coding RNA to amplify protein production
Scientists from an international group led by the RIKEN Center for Integrative Medical Sciences and Yokohama City University have discovered that a pair of proteins play a key role in allowing an important type of functional non-coding RNA, known as SINEUPs, to act to promote their target messenger RNA. SINEUPs are a recently discovered type of RNA that work specifically to amplify the production of proteins by messenger RNAs, and hence could be important for developing therapeutics for diseases where a certain protein is insufficiently synthesized.

Analysis of a Martian meteorite reveals evidence of water 4.4 billion years ago
A meteorite that originated on Mars billions of years ago reveals details of ancient impact events on the red planet. Certain minerals from the Martian crust in the meteorite are oxidized, suggesting the presence of water during the impact that created the meteorite. The finding helps to fill some gaps in knowledge about the role of water in planet formation.
