Probing biology's dark matter

...lves to direct individual rod-shaped bacteria into miniature chambers. Once individual microbes were isolated, the researchers could extract the DNA and amplify it using routine methods. In this way, the researchers were able to sequence and assemble more than 1,000 genes, providing insight into the physiolo...

...d-pulse facilitation and an increased frequency of miniature EPSCs, consistent with a presynaptic site of action for BMP. Nerve terminals in Chrd-/- mice also had an increase in docked vesicles. Perfusion of BMP2 in wild-type slices mimicked the effects seen in slices from Chrd-/- mice. The effects on plastici...

Penn researchers discover how microRNAs control protein synthesis

...oteins as determined by the cells immediate needs, miniature pieces of RNA, called microRNAs (miRNAs) regulate gene expression. Recently, researchers from the University of Pennsylvania School of Medicine determined how miRNAs team up with a regulatory protein to halt protein production. Results of the study w...

Researchers demonstrate way to control tree height

...ight of trees, showing that its possible to create miniature trees that look similar to normal trees but after several years of growth may range anywhere from 50 feet tall to a few inches. This is a proof of concept that tree height can be readily controlled by genetic engineering techniques. It opens the d...

NJIT professor obtains patent to uncover trace elements of airborne pollutants

... Although the market currently features affordable miniature sensors, the technology is not there yet for the tiniest amounts of pollutants, said Mitra. "I'm talking about creating an instrument sensitive enough to measure concentrations of pollutants such as benzene, which may range in just a few parts per ...

New sensor detects gaseous chemical weapon surrogates in 45 seconds

...ch in turn creates a very small acoustic signal. A miniature quartz tuning fork acts as a "microphone" to record the resulting sound wave. PNNL researchers paired multiple QCLs with the tuning forks, allowing simultaneous examination of a single sample at many infrared wavelengths. Nearly every molecule has ...

Press conferences at the year's largest physics meeting

...-ASSEMBLED VIRUS-LIKE PARTICLES Some lab-on-a-chip miniature test systems rely on bubbles to carry samples and reagents, or use bubbles to control the flow of various components through the system. Manu Prakash and colleagues at MIT have taken the approach to a whole new level by developing bubble-based device...

MIT develops nanoparticles to battle cancer

...ising nanoparticle solutions that, while not quite miniature surgical teams, do have the potential to help identify tumors and deliver chemotherapy locally. One solution already under way involves using nanoparticles for cancer imaging. By slipping through tiny gaps that exist in fast-growing tumor blood ve...

The researchers note, however, that getting those fluids to mix with chemicals in clinical tests and flow poses huge challenges because of difficulties in fabricating tiny pumps. Researchers thus are exploring ...
