Iron-based process promises greener, cheaper, safer drug, perfume production Posted: 28 Nov 2013 11:14 AM PST Researchers have developed a series of techniques to create a variety of very active iron-based catalysts necessary to produce the alcohols and amines used in the drug and perfume industry. The new synthetic methods promise to be safer and more economical and environmentally friendly than traditional industrial processes.

Scientists stitch up photosynthetic megacomplex Posted: 28 Nov 2013 11:13 AM PST Scientists report on a new technique that allowed them to extract a photosynthetic megacomplex consisting of light antenna and two reaction centers from the membrane of a cynaobacterium. This is the first time an entire complex has been isolated and studied as a functioning whole.

Pushing limits of light microscopy Posted: 28 Nov 2013 10:39 AM PST A team of researchers established a new microscopy technique which greatly enhances resolution in the third dimension. In a simple set-up, the scientists used the translation of position information of fluorescent markers into color information. Overcoming the need for scanning the depth of a sample, they were able to generate the precise 3D information at the same speed as it would take to acquire a 2D image.

Using moving cars to measure rainfall Posted: 28 Nov 2013 07:38 AM PST Drivers on a rainy day regulate the speed of their windshield wipers according to rain intensity: faster in heavy rain and slower in light rain. This simple observation has inspired researchers to come up with 'RainCars', an initiative that aims to use GPS-equipped moving cars as devices to measure rainfall.

Physicists study coldest objects in universe Posted: 27 Nov 2013 07:54 PM PST In a new study, a group of researchers has come up with a new way of measuring BECs by using a filter to cancel out the damage caused by the streams of light that are typically used to measure them. Some of these BECs are the coldest objects in the universe, and are so fragile that even a single photon can heat and destroy them.

Public health data to help fight deadly contagious diseases Posted: 27 Nov 2013 07:54 PM PST In an unprecedented windfall for public access to health data, researchers have digitized all weekly surveillance reports for reportable diseases in the US going back 125 years. Supported by the Bill & Melinda Gates Foundation and the National Institutes of Health, the project's goal is to aid in the eradication of devastating diseases.

Simulating new treatment for retinal degeneration Posted: 27 Nov 2013 07:53 PM PST For a few years, optogenetics has been seen as a very promising therapy for progressive blindness, for example when it is a result of retinal degeneration. In order to further develop this therapeutic approach, researchers have developed a computer model that simulates optogenetic vision.
