Scientists found hundreds of toxic chemicals in recycled plastics      (via sciencedaily.com)     Original source 

When scientists examined pellets from recycled plastic collected in 13 countries they found hundreds of toxic chemicals, including pesticides and pharmaceuticals. Because of this, the scientists judge recycled plastics unfit for most purposes and a hinder in the attempts to create a circular economy.

Bacteria-virus arms race provides rare window into rapid and complex evolution      (via sciencedaily.com)     Original source 

Rather than a slow, gradual process as Darwin envisioned, biologists can now see how evolutionary changes unfold on much more accelerated timescales. Using an accelerated arms race between bacteria and viruses, researchers are documenting rapid evolutionary processes in simple laboratory flasks in only three weeks.

Advances in lithium-metal batteries, paving the way for safer, more powerful devices      (via sciencedaily.com)     Original source 

The boom in phones, laptops and other personal devices over the last few decades has been made possible by the lithium-ion (Li-ion) battery, but as climate change demands more powerful batteries for electric vehicles and grid-scale renewable storage, lithium-ion technology might not be enough. Lithium-metal batteries (LMBs) have theoretical capacities an order of magnitude greater than lithium-ion, but a more literal boom has stymied research for decades.

Cracking the code: Genome sequencing reveals why songbirds are larger in colder climates      (via sciencedaily.com)     Original source 

Scientists have unlocked the genetic basis underlying the remarkable variation in body size observed in song sparrows, one of North America's most familiar and beloved songbirds. This discovery also provides insights into this species' capacity to adapt to the challenges of climate change. The study used genomic sequencing to successfully pinpoint eight genetic variants, or DNA mutations, largely responsible for the nearly threefold difference in body size observed across the song sparrow range from Mexico to Alaska.

The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal      (via sciencedaily.com)     Original source 

Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.
