Clingfish biology inspires better suction cup

A team of engineers and marine biologists built a better suction cup inspired by the mechanism that allows the clingfish to adhere to both smooth and rough surfaces. Researchers reverse engineered the clingfish's suction disk and developed devices that cling well to wet and dry objects both in an out of water. The devices can hold up to hundreds of times their own weight.

3-D printed coral could help endangered reefs

Threats to coral reefs are everywhere — rising water temperatures, ocean acidification, coral bleaching, fishing and other human activities. But new research shows that 3-D printed coral can provide a structural starter kit for reef organisms and can become part of the landscape as fish and coral build their homes around the artificial coral.

What gives a 3-meter-long Amazonian fish some of the toughest scales on Earth

Arapaima gigas is a big fish in a bigger river full of piranhas, but that doesn't mean it's an easy meal. It's evolved armor-like scales that deform, but don't tear or crack, when a piranha — which has one of the animal kingdom's most powerful bites — attacks. Researchers describe the unique properties of the Amazonian Arapaima skin and its potential for human-made materials.

Artificial intelligence and farmer knowledge boost smallholder maize yields

Farmers in Colombia's maize-growing region of Córdoba had seen it all: too much rain one year, a searing drought the next. Yields were down and their livelihoods hung in the balance. To better deal with climate stress, farmers in Colombia's maize-growing region of Córdoba needed information services that would help them decide what varieties to plant, when they should sow and how they should manage their crops.

Survival strategy found in living corals which was only seen in fossil records

Some corals can recover after massive mortality episodes caused by the water temperature rise. This survival mechanism in the marine environment — known as rejuvenation — had only been described in some fossil corals so far. A new study reveals the first scientific evidence of the rejuvenation phenomenon in vivo in Cladocora caespitosa coral colonies, in the marine reserve in Columbrets, in the coast of Castellón.

Many cooks don't spoil the broth: Manifold symbionts prepare the host for any eventuality

Deep-sea mussels, which rely on symbiotic bacteria for food, harbor a surprisingly high diversity of these bacterial 'cooks': Up to 16 different bacterial strains live in the mussel's gills, each with its own abilities and strengths. Thanks to this diversity, the mussel is prepared for all eventualities, researchers report.

Achieving a safe and just future for the ocean economy

much attention has been given to the growth of the 'Blue Economy' — a term which refers to the sustainable use of ocean and marine resources for economic growth, jobs, and improved livelihoods. Ocean resources are viewed as lucrative areas for increased investment, including in fisheries, aquaculture, bio-prospecting, renewable energy, oil and gas, and other businesses. Ensuring that socially equitable and sustainable development occurs should be the mandate of governments and industry, maintain an international group of researchers, led by UBC.
