Scientists at Argonne National Laboratory have discovered a possible mechanism to control chirality in biological molecules. Chirality, or 'handedness,' is a trait existing in the basic molecules of all living things, and controlling it has long been a goal of researchers. By changing the magnetization direction of some chiral molecules in relation to a high-intensity X-ray beam, an excess of one form of chirality was created over another. Understanding such basic occurrences in the building blocks of matter could be an important step to understanding the origin of life.

Researchers are looking to put micro-robots to work as internal surgeons. The hope is that some of these tablet-shaped robots could perform certain gastrointestinal operations without injuring the patient's body. The process would begin with the swallowing of individual parts of the robot, which would then self-assemble into a more powerful system to perform the task. The feasibility of such an operation is currently being tested in artificial stomachs.

The design of surgical implants will soon be undergoing a revolutionary change. So says a team of researchers at the Science and Technology Facilities Council (STFC) and their supportive peers. The team has succeeded in coating surgical implants with "intelligent" fibers that will facilitate bonding action to the living bone. This bonding technique, said to be the first of its kind, will last throughout the patient's lifetime, and will improve the reliability and durability of the implant.

Perpetually powered data acquisition? You heard right. GE Energy has recently developed wireless sensors with an endless power supply. The sensors harvest and use vibration energy from the very machines they monitor. How? The system uses a micro-generator to transform vibrational energy into serviceable electrical energy. It also stores that energy in a super-capacitor; during peak operational phases, there will still be enough power for data measurement and transfer.

How does one acquire data in temperatures that sometimes drop to -80° C? Embedded technologies are the answer, allowing researchers to gather data in extreme situations such as at the South Pole. Find out how an IceCube experiment is being developed to detect neutrinos by recording flashes of light through a telescope, or by measuring the acoustics involved in a neutrino collision. These data acquisition systems have all been designed to be rugged, stable, and cold-rated.

Measuring the presence of dark matter is a task that's, well, out of this world. A newly developed detector out of MIT can help aid in this pursuit. Existing detectors are flawed in that they continue to pick up the presence of ordinary matter. However, these detectors, when run simultaneously with the new device, can identify the presence of all ordinary neutrons, leaving the dark matter detector to locate any other signals as a strong candidate for identification as dark matter

Respiratory measurement technology is being fine-tuned at a new research facility, and the hope is that researchers can use their discoveries for several applications. One such example is in the realm of breath monitoring. Breath monitoring can be a crucial tool in the diagnosis of respiratory conditions. One problem that researchers have overcome is how to collect data from a normal breath, as opposed to making the patient exhale forcefully — a task that can be impossible for seriously ill patients.

The current state of nanotechnology safety in the U.S. is woefully inadequate says a new report. The main issue appears to be a lack of research to provide the public with information that can improve acceptance and understanding of the benefits of nanotechnology. The report also calls on the Obama administration to consider a new strategy for identifying and managing potential risks.

Latest word out of the Agricultural Research Service (ARS) is that nanotechnology could play a big role in food safety. Specifically, ARS has developed a microscopic biological sensor that can detect the presence of salmonella bacteria. Researchers used nanotechnology principles to help develop the sensor, and include fluorescent organic dye particles that attach to the bacteria, making it easier to spot.
