Conventional biological wisdom holds that living cells interact with their environment through an elaborate network of chemical signals, which is most therapies rely on drugs that block chemical signals. Scientists can now show, however, for the first time, that direct physical force can also change the way cellular proteins conduct chemical activity.

Researchers have been able to see how heart failure affects the surface of an individual heart muscle cell in minute detail, using a new nanoscale scanning technique developed at Imperial College London. The findings may lead to better design of beta-blockers.

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.

A Northwestern Univ. study shows that coupling a magnetic resonance imaging (MRI) contrast agent to a nanodiamond results in dramatically enhanced signal intensity and, thus, vivid image contrast.

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.

Scientists have shown for the first time that insects, like
mammals, use vision rather than touch to find footholds. They made the
discovery using high-speed video cameras—the same technology the BBC uses to
capture its stunning wildlife footage—that they used to film desert locusts
stepping along the rungs of a miniature ladder.

When using a fluorescence imaging microscope, a staple for life science research, researchers usually have to invest in dark rooms. Knowing that researchers’ time is precious, as well as the space they work in, Olympus created the FSX100 and the FluoView FV10i microscopes, that allow researchers to actually save space in laboratories and remove the need for dark rooms for fluorescence imaging experiments.

“T-rays” may make X-rays obsolete as a means of detecting bombs on terrorists or illegal drugs on traffickers, among other uses, contends a Texas A&M physicist who is helping lay the theoretic groundwork to make the concept a reality. In addition to being more revealing than X-rays in some situations, T-rays do not have the cumulative possible harmful effects.

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.

By producing some of the highest resolution images of peptides attaching to mineral surfaces, scientists have a deeper understanding how biomolecules manipulate the growth crystals. This research may lead to a new treatment for kidney stones using biomolecules.
