Better understanding of soft artificial muscles  

Artificial muscles will power the soft robots and wearable devices of the future. But more needs to be understood about the underlying mechanics of these powerful structures in order to design and build new devices. Now, researchers have uncovered some of the fundamental physical properties of artificial muscle fibers.

Amazon deforestation and number of fires show summer of 2019 not a 'normal' year  

The perceived scale of the Amazon blazes received global attention this summer. However, international concerns raised at the time were countered by the Brazilian Government, which claimed the fire situation in August was 'normal' and 'below the historical average'. An international team of scientists writing in the journal Global Change Biology say the number of active fires in August was actually three times higher than in 2018 and the highest number since 2010.

Plants use a single communication route when developing new chloroplasts  

When a plant begins growing its first leaves, it is in a race for survival to build its chloroplasts. Research reveals that a chain of communication from the developing chloroplast to the cell's central DNA center, the nucleus, is controlled in-part by a protein that defied characterization for the past quarter-century and there is also a role for a molecule recently made famous by the plant-based 'meat' industry: plant heme.

How nematodes outsmart the defenses of pests  

The western corn rootworm, one of the world's most damaging maize pests, can use plant defense compounds to defend itself against its own natural enemies, so-called entomopathogenic nematodes. However, the nematodes can become immune against these compounds in turn, which enhances their ability to fight the western corn rootworm, as researchers show. This mechanism may contribute to improving biological pest control.

Going with the floe: Sea ice movements trace dynamics transforming the new Arctic
