A new study reveals that marine cyanobacteria communicate      (via sciencedaily.com)     Original source 

A breakthrough study changes the way we understand cyanobacteria, which are essential for the sustenance of life. The study shows that these organisms do not operate in isolation, but rather physically interact through membrane-nanotubes, which function as exchange bridges between cells.

Researchers solve 2,000-year-old mystery of the shipworm      (via sciencedaily.com)     Original source 

They bedeviled ancient Greek navies, helped shipwreck Christopher Columbus, aided in the sinking of the Spanish Armada and caused the wharves in San Francisco Bay to collapse into the sea, but until now, scientists have been unable to pinpoint exactly how shipworms -- a family of mollusks -- are able to cause such damage. A team of researchers has discovered that a population of symbiotic microbes, living in an overlooked sub-organ of the gut called the 'typhlosole,' have the ability to secrete the enzymes needed to digest lignin -- the toughest part of wood.

Blood sausages and yak milk: Bronze Age cuisine of Mongolian nomads unveiled      (via sciencedaily.com)     Original source 

Bronze cauldrons were used by the inhabitants of the Mongolian steppe around 2,700 years ago to process animal blood and milk. This is shown by a protein analysis of archaeological finds from this period.

'Missing' early sea sponges discovered      (via sciencedaily.com)     Original source 

Geobiologists reported a 550 million-year-old sea sponge that had been missing from the fossil record. The discovery sheds new light on a conundrum that has stumped zoologists and paleontologists for years.

Mapping lava flows with groundbreaking field instrument      (via sciencedaily.com)     Original source 

Researchers develop a tool for measuring the viscosity of lava that could increase our understanding of molten rock as well as better improve models of its movement, giving authorities crucial guidance for keeping people safe. They attached a metal rod to a force gauge for accurate measurements and coupled it with a second rod to measure displacement. The entire instrument is designed to be both lightweight enough to be hand-held and durable enough to hold up in a volcanic environment.

An unlikely hero in evolution: Worms      (via sciencedaily.com)     Original source 

One of Earth's most consequential bursts of biodiversity -- a 30-million-year period of explosive evolutionary changes spawning innumerable new species -- may have the most modest of creatures to thank for the vital stage in life's history: worms.

'Ugly' fossil places extinct saber-toothed cat on Texas coast      (via sciencedaily.com)     Original source 

This fossil looks like a lumpy, rounded rock with a couple of exposed teeth that are a little worse for wear, having been submerged and tumbled along the floor of the Gulf of Mexico for thousands of years before washing up on a beach. But when it was X-rayed a doctoral student saw there was more to the fossil that met the eye: a hidden canine tooth that had not yet erupted from the jaw bone. It was just what researchers needed to identify the fossil as belonging to a Homotherium, a genus of large cat that roamed much of the Earth for millions of years.

Scientists invent 'living bioelectronics' that can sense and heal skin      (via sciencedaily.com)     Original source 

Reaserchers have created a prototype for what they call 'living bioelectronics': a combination of living cells, gel, and electronics that can integrate with living tissue. Tests in mice found that the devices could continuously monitor and improve psoriasis-like symptoms, without irritating skin.

Acute sense of touch helps hummingbirds hover near a flower without bumping into it      (via sciencedaily.com)     Original source 

Hummingbird flight mechanics have been well studied but far less is known about how their sense of touch helps them sip nectar from a flower without bumping into it. Most of what scientists know about how touch is processed in the brain comes from studies on mammals, but bird brains are very different from mammal brains. New research shows that touch and air pressure on the wings and legs activate specific clusters of neurons in two regions of the forebrain to create a map of their body, which may help hummingbirds make nuanced adjustments to flight.
