The fascinating relationship between mice and a plant that flowers once a century in terms of seed dispersal      (via sciencedaily.com)     Original source 

Researchers have discovered several factors that affect field mouse behavior using seeds from dwarf bamboo plants, a plant that flowers once in a century. Their findings not only suggest the previously underappreciated role of mice in the forest ecosystem, but also show that they store small sasa seeds for later use. These challenge a previously held model of mouse behavior.

Two fins are better than one: Fish synchronize tail fins to save energy      (via sciencedaily.com)     Original source 

They say two heads are better than one. But in the world of fish, it appears two fins are better than one. Researchers have produced a theoretical model that demonstrates the underlying mechanisms behind how fish will synchronize their fin movements to ride each other's vortices, thereby saving energy.

A new study that combines genetic and molecular techniques helps solve the riddle of sea star (commonly called starfish) body plans, and how sea stars start life with bilateral body symmetry -- just like humans -- but grow up to be adults with fivefold 'pentaradial' symmetry.

How sunflowers see the sun      (via sciencedaily.com)     Original source 

Sunflowers famously turn their faces to follow the sun as it crosses the sky. But how do sunflowers 'see' the sun to follow it? Plant biologists show that they use a different, novel mechanism from that previously thought.

New species of mosasaur named for Norse sea serpent      (via sciencedaily.com)     Original source 

Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.

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.

Scrape, cluck, lay eggs -- that's it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental conditions -- a finding that points beyond the experiment with roosters and could also be of importance for other animal species.

What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.

Finding the genes that help kingfishers dive without hurting their brains      (via sciencedaily.com)     Original source 

Scientists studied the genomes of 30 kingfisher species to try to identify the genes that allow kingfishers to dive headfirst into water without huring their brains. The researchers found that the diving birds have unusual mutations to the genes that produce tau: a protein that helps stabilize tiny structures in the brain, but which can build up in humans with traumatic brain injuries or Alzheimer's disease. The researchers suspect that these variations in the kingfishers' tau proteins might protect their brains when they dive.
