Crust-forming algae are displacing corals in tropical waters worldwide      (via sciencedaily.com)     Original source 

Over the past few decades, algae have been slowly edging corals out of their native reefs across the globe by blocking sunlight, wearing the corals down physically, and producing harmful chemicals. But in recent years, a new type of algal threat has surfaced in tropical regions like the Caribbean -- one that spreads quickly and forms a crust on top of coral and sponges, suffocating the organisms underneath and preventing them from regrowing. Marine biologists report that peyssonnelioid alga crusts, or PACs, are expanding quickly across reefs worldwide, killing off corals and transforming entire ecosystems.

Large herbivores such as elephants, bison and moose contribute to tree diversity      (via sciencedaily.com)     Original source 

Using global satellite data, a research team has mapped the tree cover of the world's protected areas. The study shows that regions with abundant large herbivores in many settings have a more variable tree cover, which is expected to benefit biodiversity overall.

To restore ecosystems, think about thwarting hungry herbivores      (via sciencedaily.com)     Original source 

Re-establishing plantings of trees, grasses and other vegetation is essential for restoring degraded ecosystems, but a new survey of almost 2,600 restoration projects from nearly every type of ecosystem on Earth finds that most projects fail to recognize and control one of the new plants' chief threats: hungry critters that eat plants.

Reverse engineering Jackson Pollock      (via sciencedaily.com)     Original source 

Researchers combined physics and machine learning to develop a new 3D-printing technique that can quickly create complex physical patterns -- including replicating a segment of a Pollock painting -- by leveraging the same natural fluid instability that Pollock used in his work.

Shifting nesting timing not enough to prevent fewer sea turtle hatchlings      (via sciencedaily.com)     Original source 

New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.

New map of 20th century land use in Britain helps researchers demystify biodiversity change      (via sciencedaily.com)     Original source 

Researchers have mapped how land use changed across Britain throughout the last century. The new map reveals how and where some 50 per cent of semi-natural grassland was lost, including 90 per cent of the country's lowland meadows and pasture, as the nation intensified its agriculture.

Amazon deforestation linked to long distance climate warming      (via sciencedaily.com)     Original source 

Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study.   The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.

Engineers develop breakthrough 'robot skin'      (via sciencedaily.com)     Original source 

Smart, stretchable and highly sensitive, a new soft sensor opens the door to a wide range of applications in robotics and prosthetics. When applied to the surface of a prosthetic arm or a robotic limb, the sensor skin provides touch sensitivity and dexterity, enabling tasks that can be difficult for machines such as picking up a piece of soft fruit. The sensor is also soft to the touch, like human skin, which helps make human interactions safer and more lifelike.
