If the price of a new innovation by researchers at Rice Univ. is right, the flat petri dish may soon become an endangered species in the lab. The “invisible scaffold” technique, which relies on gold nanoparticles and engineered phages, builds cultures that more closely resemble native tissue.

Typical microfluidic devices require complicated etching of tiny channels into glass, silicon or metal. As Australian researchers have discovered, cotton thread can be an effective alternative. The fibers wick fluids effectively, and when attached to paper they form a low-cost sensor.

Many of the patients studied recently in research published in the New England Journal of Medicine were labeled with the same diagnosis: "vegetative state." Their head injuries condemned them to remain alive yet devoid of awareness of the world around them. But peeking inside their minds has revealed activity that has eluded scientists until now.

Comparing their discovery to the deciphering of hieroglyphics using the Rosetta Stone, Carnegie Mellon researchers have combine brain imaging and machine learning methods to understand how the brain codes nouns. The brain’s coding process for nouns, for example, depends on three basic factors.

Some of the young amphibians in a Univ. of Wyoming lab have been engineered to light up in response to metals. Others fluoresce when exposed to pollution from plastic. Better still, the glowing tadpoles indicate whether pollution exists in a form that can be absorbed by an organism.

The past several decades have heralded a revolution in the fundamental understanding of disease and disease progression. In particular, researchers have come to recognize the interconnectivity that exists between cellular tissue and organ systems in mammals, and that one system can no longer be studied in isolation.

In an attempt learn more about how cells move and why, Brown Univ. and Caltech researchers tracked movements over a 24-hour period using confocal microscopy and digital volume correlation. The movements, they found, were surprising complex and occurred in three dimensions.

Synthetic blood cells made at UC Santa Barbara retain 90% of their oxygen-binding capacity after a week, all while closely mimicking the characteristics of red blood cells, including softness and flexibility. They are not designed to replace real cells. They instead will be carriers for therapeutic and diagnostic agents.

A Univ. of Rochester optics professor made headlines when he changed the color of everyday metals by scouring their surfaces with precise, high-intensity laser bursts. Suddenly it was possible to make sheets of golden tungsten, or black aluminum. A recent discovery has shown that, beyond the aesthetic opportunities in his find lie some very powerful potential uses, like diagnosing some diseases with unprecedented ease and precision.

One of the promises of nanomedicine is the design of tiny particles that can home in on diseased cells and get inside them. Nanoparticles can carry drugs into cells and tag cells for MRI and other diagnostic tests; and they may eventually even enter a cell's nucleus to repair damaged genes. Unfortunately, designing them involves as much luck as engineering.
