Some coastal salt marshes are keeping up with sea level rise -- for now      (via sciencedaily.com) 

The world's salty, tidal marshes are hotspots of carbon storage and productivity, building up sediments and plant material to stay above sea level. However, as sea level rises at an increasing rate, scientists debate whether it's possible for wetlands to win the race. New research reveals how salt marshes along the U.S. East Coast have responded to accelerating sea level rise by building elevation more quickly to keep pace with the sea over the last century.

Colorful films could help buildings, cars keep their cool      (via sciencedaily.com) 

The cold blast of an air conditioner can be a relief as temperatures soar, but 'A/C' units require large amounts of energy and can leak greenhouse gases. Today, scientists report an eco-friendly alternative -- a plant-based film that cools when exposed to sunlight and comes in many textures and bright, iridescent colors. The material could someday keep buildings, cars and other structures cool without requiring power.

Surprise effect: Methane cools even as it heats      (via sciencedaily.com) 

Most climate models do not yet account for a recent discovery: methane traps a great deal of heat in Earth's atmosphere, but also creates cooling clouds that offset 30% of the heat.

Climate change threatens global fisheries      (via sciencedaily.com) 

The diet quality of fish across large parts of the world's oceans could decline by up to 10 per cent as climate change impacts an integral part of marine food chains, a major study has found.

Habitat will dictate whether ground beetles win or lose against climate change      (via sciencedaily.com) 

The success of North American crops from corn to Christmas trees partly depends on a relatively invisible component of the food web -- ground beetles. Nearly 2,000 species of ground beetle live in North America. New research shows that some of these insects could thrive while others could decline as the climate changes. The team found that the response will largely depend on the species' traits and habitats and could have significant implications for conservation efforts.

Phytoplankton blooms offer insight into impacts of climate change      (via sciencedaily.com) 

The first study into the biological response of the upper ocean in the wake of South Pacific cyclones could help predict the impact of warming ocean temperatures, researchers believe.

Robot caterpillar demonstrates new approach to locomotion for soft robotics      (via sciencedaily.com) 

Researchers have demonstrated a caterpillar-like soft robot that can move forward, backward and dip under narrow spaces. The caterpillar-bot's movement is driven by a novel pattern of silver nanowires that use heat to control the way the robot bends, allowing users to steer the robot in either direction.

Sea ice will soon disappear from the Arctic during the summer months -- and it has happened before      (via sciencedaily.com) 

In a new study, an international team of researchers warn that the Arctic Sea ice may soon be a thing of the past in the summer months. This may have consequences for both the climate and ecosystems. Ten thousand years ago, the ice melted at temperatures similar to those we have today.

Human and ocean health impacts of ocean plastics      (via sciencedaily.com) 

Researchers from the fields of healthcare, ocean science, and social science have collaborated to quantify plastic's considerable risks to all life on Earth. The Minderoo-Monaco Commission on Plastics and Human Health report presents a comprehensive analysis showing plastics as a hazard at every stage of their life cycle.

Jellyfish size might influence their nutritional value      (via sciencedaily.com) 

Researchers confirmed what was already known: jellyfish eat bigger prey as they grow, which means they also occupy a higher position in the food web as they grow. They also found that some of the concentrations of 'healthy fats,' increase as jellyfish grow. These changes might be influenced by their diet, and as they feed on bigger prey with higher levels of fatty acids, the jellyfish accumulate more of these fatty acids.

Coffee plantations limit birds' diets      (via sciencedaily.com) 

A new study explores a record of birds' diets preserved in their feathers and radio tracking of their movements to find that birds eat far fewer invertebrates in coffee plantations than in forests, suggesting that the disturbance of their ecosystem significantly impacts the birds' dietary options.
