Nanotechnology In Reverse Uses Red Blood Cell To Calibrate Atomic Force Microscope
|
|
Nanotechnology researchers have shown that they can use a red blood cell to calibrate a sensitive instrument, an atomic force microscope. An atomic force microscope uses a tiny lever that runs over the surface of an object. Small deflections of the tip are read and translated to produce an image of the object's surface. However, accurate calibration of the springiness of the tip is difficult.

Scientists Aim To Unlock Deep-sea 'Secrets' Of Earth's Crust
|
|
Scientists will use robots to explore the depths of the Atlantic Ocean to study the growth of underwater volcanoes that build the Earth's crust. During the five-week expedition they will use explorer robots to map individual volcanoes on the Mid-Atlantic Ridge tectonic plate boundary -- which effectively runs down the centre of the Atlantic Ocean - almost two miles (3km) below the surface of the sea.

Novel enzyme inhibitor paves way for new cancer drug
|
|
(The Wistar Institute) Wistar Institute scientists have developed a new type of enzyme inhibitor capable of blocking a biochemical pathway that plays a key role in cancer development. Based on studies in human melanoma cells, the research paves the way for developing new ways to treat cancer by dampening overactive enzyme activity that leads to uncontrolled tumor growth. The study shows how small-molecule inhibitors can be designed to target a family of signaling proteins, called phosphatidyl-inositol-3-kinases, or PI3Ks.

Separation from mom, dad linked with learning trouble in kids
|
|
(University of Rochester Medical Center) In the wake of divorce, illness, violence and other problems that can unsettle homes, countless young children are liable to experience temporary separations from one or both parents before packing their knapsacks for kindergarten. Published in the May/June issue of Ambulatory Pediatrics, a new, community-wide study from Rochester, New York, warns that such kids are at increased risk for learning difficulties.

MIT crafts bacteria-resistant films
|
|
(Massachusetts Institute of Technology) Having found that whether bacteria stick to surfaces depends partly on how stiff those surfaces are, MIT engineers have created ultrathin films made of polymers that could be applied to medical devices and other surfaces to control microbe accumulation.

Animal behavior turned into robots and more at 4th international AMAM symposium
|
|
(Case Western Reserve University) Building a machine that moves like a cockroach, salamander, fish or another creature is no easy task. Over 100 of the world's pioneering engineers, biologists and neuroscientists who have contributed to building biologically inspired robots will be on the campus of Case Western Reserve University, June 1-6, to discuss new developments in the field of biorobotics during the Fourth International Symposium on Adaptive Motion of Animals and Machines.

UCSD quake simulation tests strength of precast concrete
|
|
In an obscure area east of Interstate 15, investigators at the UC San Diego Camp Elliott Structural Research Center are testing the strength and flexibility of precast concrete. The goal of the $2.3-million project, funded by government and industry, is to provide better designs to keep buildings from coming apart during large quakes.

Such systems are still very much works in progress: Japan, Mexico, and Taiwan are deploying them, but most other nations, including the United States, are still in the research stages, says a leading seismologist, Haroo Kanamori.
