Have you had a chance to see this video from Discovery News showing the flashy ‘disco clam’? A graduate student at UC Berkeley, Lindsey Dougherty, unraveled the mystery of this party-like effect. The clams actually have tiny silica spheres (340 nanometers in diameter) on the inside of their lips that reflect light whereas the outside of…

A recent article published in the American Journal of Physiology reviewed how the brain regulates feeding behaviors. Humans are not the only species to eat food in spurts we like to call meals. Research suggests that this behavior may actually aid survival as it reduces exposure time to the environment and makes responding to fluctuations in the…

A research group at Lawrence Livermore National Laboratory has produced ultrastiff ultralowdensity metamaterials by 3D printing of microarchitected microlattices. This is very cool – they do additive 3D printing using microstereolithography with nanocoating and postprocessing and can make self-similar lattices with densities varying by several orders of magnitude in bulk density but near constant stiffness.…

Venomous ticks??

Ticks are blood-sucking arthropods that can act as vectors for various diseases in both animals and humans. A recent article published in Frontiers in Zoology summarizes findings that suggest ticks may also be considered venomous ectoparasites. For example, Ixodes holocyclus is a species of Australian tick whose saliva can induce paralysis in humans and animals. According to the new article, about…

Bone-house wasps

A new species of spider wasp that protect their young with walls made of ant carcasses has been discovered in the forests of China. Dr. Michael Staab from the University of Freiburg discovered the new species which he named Deuteragenia ossarium meaning “bone-house wasp” since the wasps reminded him of the ossuaries in Europe with…

Kangaroo’s 5th leg

New research suggests that kangaroos use their tails as a 5th “leg”:

The Bottleneck Years by H.E. Taylor Chapter 97 Table of Contents Chapter 99 Chapter 98 The Second Day, March 21, 2061 On Monday morning, I watched the second session of Jon’s trial alone in my office at CCU. I didn’t have a class until mid-afternoon, so time was not an issue. Jon was led into…

  It is not surprising that Biwa salmon (image above), a subspecies of Oncorhyncus masou, do not adapt to seawater very well after having been landlocked in Lake Biwa, Japan for the last 500,000 years or so.  Researchers from Hokkaido University and Shiga Prefecture Fishery Experiment Station in Japan wanted to know what caused the salmon to…

New research published in PLOS Genetics shows that starving C. elegans (Caenorhabditis elegans) during the late larval stage of development when the worms are undergoing tissue growth and formation halts cellular activity at previously unknown checkpoints in their development. These findings show that nutrition is an important cue to signal whether or not the worms should…
