Single Device Can Measure Hundreds Of Biomolecular Interactions
2012-09-26 07:42:18

Scientists at EPFL and the University of Geneva have developed a microfluidic device smaller than a domino that can simultaneously measure up to 768 biomolecular interactions. Inside our cells, molecules are constantly binding and separating from one another. It´s this game of constant flux that drives gene expression asides essentially every other biological process. Understanding the specific details of how these interactions take place is thus crucial to our overall...

Low-powered Nanotweezers May Benefit Cellular-level Studies By Demonstrating New Capabilities
2012-09-17 17:08:19

Using ultra-low input power densities, researchers at the University of Illinois at Urbana-Champaign have demonstrated for the first time how low-power “optical nanotweezers” can be used to trap, manipulate, and probe nanoparticles, including fragile biological samples. “We already know that plasmonic nanoantennas enhance local fields by up to several orders of magnitude, and thus, previously showed that we can use these structures with a regular CW laser source to make...

In a new study, UT Dallas researchers outline how they used fluorescent molecules to “tag” DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells. The UT Dallas “tag and track” method not only sheds light on how DNA loops form, but also might be adapted to screen drugs for effectiveness against certain viruses that shuffle genetic material, such as  HIV. Until now,...

Glowing Molecules Help Scientists Track Serotonin

[ Watch the Video ] John Neumann for redOrbit.com - Your Universe Online Researchers have succeeded in tracking a single protein that regulates the neurotransmitter serotonin, making it possible to study the dynamics of the protein which regulates mood, appetite and sleep, at an unprecedented level of detail, reports David Salisbury of Vanderbilt University. Attempts to understand how these transporters work have been limited by the difficulty of studying their dynamic behavior. The...

Tiny Creatures Captured With Ultrasound Using Acoustic Tweezers
2012-06-29 11:44:26

A device about the size of a dime can manipulate living materials such as blood cells and entire small organisms, using sound waves, according to a team of bioengineers and biochemists from Penn State. The device, called acoustic tweezers, is the first technology capable of touchlessly trapping and manipulating Caenorhabditis elegans (C. elegans), a one millimeter long roundworm that is an important model system for studying diseases and development in humans. Acoustic tweezers are also...

FCC To Re-Evaluate Cellphone Safety Standards
2012-06-17 06:15:20

The US Federal Communications Commission (FCC) is planning to take another look at their 15-year-old cell phone safety standards to determine whether or not users of the mobile devices are being adequately protected from emitted radiation, various media outlets reported over the weekend. On Friday, FCC Chairman Julius Genachowski sent out a notice of inquiry to fellow commissioners, asking them to conduct a new investigation in order to answer a series of questions regarding the current...

There's nothing like a new pair of eyeglasses to bring fine details into sharp relief. For scientists who study the large molecules of life from proteins to DNA, the equivalent of new lenses have come in the form of an advanced method for analyzing data from X-ray crystallography experiments. The findings, just published in the journal Science, could lead to new understanding of the molecules that drive processes in biology, medical diagnostics, nanotechnology and other fields. Like...

Max Planck scientists decipher the structure of bacterial injection needles at atomic resolution The plague, bacterial dysentery, and cholera have one thing in common: These dangerous diseases are caused by bacteria which infect their host using a sophisticated injection apparatus. Through needle-like structures, they release molecular agents into their host cell, thereby evading the immune response. Researchers at the Max Planck Institute for Biophysical Chemistry in...
