micro-motors small enough to be injected into the human bloodstream.

A range of complex surgical operations necessary to treat stroke victims, confront hardened arteries or address blockages in the bloodstream are about to be made safer as researchers from the Micro/Nanophysics Research Laboratory at Australia’s Monash University put the final touches to the design of micro-motors small enough to be injected into the human bloodstream.

Gecko-Like Adhesive That Lets Go

Gecko-Like Adhesive That Lets Go 

Special tips on gecko hairs can grip and release.

Gecko feet have long been a source of inspiration to scientists striving to make superstrong, reusable adhesives. Now researchers at Carnegie Mellon University have found a new way to make such an adhesive grip and release as required, using angled microstructures. These structures mimic the tips of the hairs found on gecko toes, which give the lizard its prowess as a climber.

Images taken with a scanning electron microscope

Today, 150 years after Darwin’s epochal “On the Origin of Species,” many questions about the molecular basis of evolution are still waiting for answers. How are signaling pathways changed by genes and by the environment enabling the development of new species? Scientists at the Max Planck Institute for Developmental Biology in Tübingen, Germany, are striving to decode the molecular basis of parasitism. Their objects of research are nematode worms.

Mini Submarines To Explore Human Body Nearing Reality

Mini Submarines To Explore Human Body Nearing Reality 

 

Ever since the 1966 Hollywood movie, doctors have imagined a real-life Fantastic Voyage  a medical vehicle shrunk small enough to “submarine” in and fix faulty cells in the body. Thanks to new research by Tel Aviv University scientists, that reality may be only three years away.

Nanotechnology In Dietary Supplements

Nanotechnology In Dietary Supplements 

The ability of the Food and Drug Administration (FDA) to regulate the safety of dietary supplements using nanomaterials is severely limited by lack of information, lack of resources and the agency’s lack of statutory authority in certain critical areas, according to a new expert report released by the Project on Emerging Nanotechnologies (PEN).

Nanoscale Imaging 

Donut shaped blood cells

By using nanoptical scanning probe microscopes, scientists are able to reveal the going-ons inside humans and animals with stunning clarity. Take the above set of donut-shaped blood cells – which have been treated with an antibiotic called phyllomelittin taken from the skin of a monkey frog – now decidedly more appetizing than when in a normal, bloody-looking state. (I’m sure many of you relaxed back into your seat Homer Simpson-style with an “Mmm… Monkey frog donuts…”)

Turn Your Clothes Into Fabric Speakers

Turn Your Clothes Into Fabric Speakers 

Transforming your clothes into speakers sounds weird, but science is working hard to bring fiction to reality. Like most of the technological breakthroughs these days, this one also seems possible with the help of nanotechnology. Researchers at Beijing’s Tsinghua University noticed that sending an audio frequency current through carbon nanotubes resulted in good quality sound.

The Power Of Nanotubes

The Power Of Nanotubes 

 The researchers at the University of Southern California

Researchers at the University of Southern California have created a a clear, colorless disk about 5 inches in diameter that bends and twists like a playing card, with a lattice of more than 20,000 nanotube transistors. It is capable of having high-performance electronics printed on it using a potentially inexpensive low-temperature process.

Vision Could Be Improved By Injecting Semiconductor Specks Into Retinas

Vision Could Be Improved By Injecting Semiconductor Specks Into Retinas 

Retina

The idea of creating a bionic eye to assist people with seriously impaired vision is definitely exciting. But installing a silicon chip into a human eyeball to assist the retinas has some drawbacks, the least of which being that the chip itself can block light from falling on areas of the retina that are healthy and still working properly. So Jeffrey Olsen at the University of Colorado Hospital has come up with a different approach.

A New Way To Detect Cancer Early

A New Way To Detect Cancer Early 

 

A prototype device employs the same magnetic phenomenon used to write data to computer hard drives.

A new system for detecting cancer proteins uses the same magnetic phenomenon that lets computer hard drives read and write data. The Stanford University researchers developing the system hope that it will detect cancer in its earlier stages, when it’s easier to treat. MagArray, a startup in Sunnyvale, CA, will commercialize the technology.
