Floating sea farms: A solution to feed the world and ensure fresh water by 2050      (via sciencedaily.com)     Original source 

The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.

Scientists find evidence of sea star species hybridization      (via sciencedaily.com) 

A new study presents genomic evidence of hybridization between two closely related species of sea stars -- Asterias rubens, the common starfish, and Asterias forbesi, known as Forbes' sea star.

What do neurons, fireflies and dancing the Nutbush have in common?      (via sciencedaily.com) 

Synchronicity is all around us, but it is poorly understood. Computer scientists have now developed new tools to understand how human and natural networks fall in and out of sync.

Lack of evidence hampers progress on corporate-led ecosystem restoration      (via sciencedaily.com) 

An international team of scientists analysed publicly available sustainability reports released by 100 of the world's largest companies and found that around two-thirds of these global corporations are undertaking ecosystem restoration. However, the results highlight that despite many businesses claiming to actively rebuild damaged ecosystems, we know very little about what is actually being achieved.

Fiber from crustaceans, insects, mushrooms promotes digestion      (via sciencedaily.com)     Original source 

Crustaceans, insects and mushrooms are rich sources of the dietary fiber chitin, which activates the immune system and benefits metabolism, according to a new study in mice.

Researchers grow embryonic humanized kidneys inside pigs for 28 days      (via sciencedaily.com)     Original source 

Researchers have successfully created chimeric embryos containing a combination of human and pig cells. When transferred into surrogate pig mothers, the developing humanized kidneys had normal structure and tubule formation after 28 days. This is the first time that scientists have been able to grow a solid humanized organ inside another species, though previous studies have used similar methods to generate human tissues such as blood or skeletal muscle in pigs.

Fossil spines reveal deep sea's past      (via sciencedaily.com)     Original source 

Right at the bottom of the deep sea, the first very simple forms of life on earth probably emerged a long time ago. Today, the deep sea is known for its bizarre fauna. Intensive research is being conducted into how the number of species living on the sea floor have changed in the meantime. Some theories say that the ecosystems of the deep sea have emerged again and again after multiple mass extinctions and oceanic upheavals. Today's life in the deep sea would thus be comparatively young in the history of the Earth. But there is increasing evidence that parts of this world are much older than previously thought.

Human shoulders and elbows first evolved as brakes for climbing apes      (via sciencedaily.com)     Original source 

Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.

Large herbivores keep invasive plants at bay      (via sciencedaily.com) 

Elephants, buffaloes and other heavy herbivores are effective against invasive plants. This is the conclusion of a new study that used Indian data, including data from the world's largest survey of wildlife based on camera traps. But smaller animals can do the same: you don't need elephants to get the same effect, the researchers point out.

Will it slip or will it grip: scientists ask, 'what is snail mucus?'      (via sciencedaily.com)     Original source 

Scientists profile the mucus of Cornu aspersum -- a snail species used in beauty product formulation and eaten as escargot -- and detail the composition of three unique types of secretions -- one that hydrates and protects its skin, another that works as a glue-like adhesive, and another that lubricates to allow the animal to move freely across surfaces.

Coastal fisheries show surprising resilience to marine heat waves      (via sciencedaily.com) 

New research found that marine heat waves -- prolonged periods of unusually warm ocean temperatures -- haven't had a lasting effect on the fish communities that feed most of the world. The finding is in stark contrast to the devastating effects seen on other marine ecosystems cataloged by scientists after similar periods of warming, including widespread coral bleaching and harmful algal blooms.

Bat study reveals how the brain is wired for collective behavior      (via sciencedaily.com)     Original source 

Researchers used wireless neural recording and imaging devices to 'listen in' on the hippocampal brain activity of groups of Egyptian fruit bats as they flew freely within a large flight room. The researchers were surprised to find that, in this social setting, the bat's 'place' neurons encoded not only the animal's location, but also information about the presence or absence of other bats, and even the identity of bats in their path.

Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution      (via sciencedaily.com)     Original source 

Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.

Broken by bison, aspen saplings having a tough time in northern Yellowstone      (via sciencedaily.com) 

In northern Yellowstone National Park, saplings of quaking aspen, an ecologically important tree in the American West, are being broken by a historically large bison herd, affecting the comeback of aspen from decades of over-browsing by elk.
