The chestnut gall wasp -- The threat of an invasive species with clonal reproduction  

A molecular study carried out on the chestnut gall wasp, Dryocosmus kuriphilus, has revealed the absence of genetic variability in this invasive species, a chestnut-tree parasite, in Europe. This is due to the fact that the wasp's reproduction is strictly parthenogenetic, the females produce more females without having to be fertilized by a male. The high capacity of reproduction of the females, producing genetically identical daughters, give this insect a high invasive potential.

Each time a blood vessel splits into smaller vessels, red blood cells (RBCs) are presented with the same decision: Take the left capillary or the right. While one might think RBCs would divide evenly at every fork in the road, it is known that at some junctures, RBCs seem to prefer one vessel over the other. One new computer model looks to determine why RBCs behave this way, untangling one of the biggest mysteries in our vascular system.

A better way to control crystal vibrations  

The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. Now, researchers have shown that by swapping out just a small fraction of a material's atoms with atoms of a different element, they can control the speed and frequencies of these vibrations.

Researchers operate lab-grown heart cells by remote control  

Researchers have developed a technique that allows them to speed up or slow down human heart cells growing in a dish on command -- simply by shining a light on them and varying its intensity. The cells are grown on a material called graphene, which converts light into electricity, providing a more realistic environment than standard plastic or glass laboratory dishes.

Blood type affects severity of diarrhea caused by E. coli  

A new study shows that a kind of E. coli most associated with 'travelers' diarrhea' and children in underdeveloped areas of the world causes more severe disease in people with blood type A. The bacteria release a protein that latches onto intestinal cells in people with blood type A, but not blood type O or B, according to a new study.

A way to prevent pancreatic cancer from spreading post-surgery?  

New research suggests a strategy for lowering the odds of metastasis following successful pancreatic cancer surgery: The post-operative period, suggests a researcher, 'offers a window during which efforts might be made to keep cortisol levels down and T cells strong so the patient's own immune system can kill the cancer cells that have made their way to other parts of the body but until this point have been dormant.'

Robotic assembly of the world's smallest house -- Even a mite doesn't fit through the door!  

A nanorobotics team has assembled a new microrobotics system that pushes forward the frontiers of optical nanotechnologies. Combining several existing technologies, the newly developed nanofactory builds microstructures in a large vacuum chamber and fixes components onto optical fiber tips with nanometer accuracy. The microhouse construction demonstrates how researchers can advance optical sensing technologies when they manipulate ion guns, electron beams and finely controlled robotic piloting.

Keep the light off: A material with improved mechanical performance in the dark  

Researchers found that zinc sulfide crystals were brittle under normal lighting conditions at room temperature, but highly plastic when deformed in complete darkness. Deformation of zinc sulfide crystals in the dark also narrowed their band gap, which controls electrical conductivity. The team's findings showed the mechanical and electronic properties of inorganic semiconductors are sensitive to light, revealing a possible route to engineer the performance of inorganic semiconductors, which are

3D-printed smart gel that walks underwater, moves objects  

Engineers have created a 3D-printed smart gel that walks underwater and grabs objects and moves them. The watery creation could lead to soft robots that mimic sea animals like the octopus, which can walk underwater and bump into things without damaging them. It may also lead to artificial heart, stomach and other muscles, along with devices for diagnosing diseases, detecting and delivering drugs and performing underwater inspections.
