ExAblate(R)MRI-guided Focused Ultrasound is effective in reducing pain from bone metastases in patients who could not undergo radiation therapy. Patients reported significant improvement in well-being, function, and reduction in medication use.

700 scientists and academicians have signed petitions calling on French researcher Gilles-Eric Seralini to release research data he claims is evidence for health problems associated with biotech crops.

The petitioners are from every continent and represent more than 40 countries. They are urging transparency in the promotion of sound science on important issues of public health and join  calls by regulatory bodies including the European Food Safety Authority (EFSA) and Food Standards Australia New Zealand (FSANZ) to Seralini and his collaborators at the Committee for Research&Independent Information on Genetic Engineering (CRIIGEN) to provide the research data to back up their allegations of health and safety risks links to GMOs.

One morning last March, engineers at General Electric’s Nela Park research lab in Cleveland, Ohio, opened a century-old time capsule hidden in a corner stone of Building 307. Inside the cavity and beneath a layer of sand was a standard 40-watt Mazda incandescent bulb made at the time of Thomas Edison.

The engineers brushed off the dirt, screwed the lamp into a socket, and slowly powered it on. The bulb’s soft yellow glow was like a faint echo from the Big Bang that set GE on course to become a global industrial powerhouse.

An assembly of thousands of nano-machines has produced a coordinated contraction movement - like that of muscle fibers, and it even extended to around ten micrometers, like the movements of muscular fibers.

The work provides an experimental validation of a biomimetic approach that has been conceptualized for years in nanoscience and the researchers believe this broadens applications in robotics, information storage and obviously artificial muscles themselves.
Dogs are susceptible to contagious yawning just like people, says an article in Animal Cognition, but only after they get older. Dogs, like humans, show a gradual development of susceptibility to contagious yawning and the new paper says dogs catch yawns from humans. But Only dogs above seven months of age catch these human yawns - younger dogs are immune to the contagion.

Contagious yawning has been researched in humans, adult chimpanzees, baboons and dogs, some speculate it can be used as a measure of empathy. Empathy, mimicking the emotional responses of others, is difficult to measure directly, but contagious yawning allows assessment of a behavioral empathetic response, the Swedish researchers say. 
A dynamic gel made of DNA mechanically responds to stimuli in much the same way that cells do. This DNA gel, at only 10 microns in width, is roughly the size of a eukaryotic cell, the type of cell of which humans are made. The miniscule gel contains within it stiff DNA nanotubes linked together by longer, flexible DNA strands that serve as the substrate for molecular motors.

We won't have artificial muscles and self-propelled goo just yet, but Omar Saleh and Deborah Fygenson of UC Santa Barbara feel like they have gotten a lot closer.
