This 350x image of the surface of a mouse colon was honored as an Image of Distinction in the 2012 Nikon Small World Photomicrophotography Competition. The nuclei, pseudocolored green, are stained with DAPI. Actin, colored red, is stained with rhodamine phalloidin.
When an E. coli cell divides, it must replicate its circular chromosome and pull the resulting circles apart to take up residence in two new cells. It sounds easy enough — like a magician's trick with rings — but actually involves a complicated process of unknotting and unlinking of tangled DNA. In a new study, an international team of scientists offers a mathematical analysis of how these rings are unlinked by XerCD recombination enzymes.

Accelrys BioRails 4.5 and Accelrys Morphit 3.0 are designed to accelerate assay pipelines, improve cascade management and enhance collaborative decision-making in discovery biology.
Eight entrepreneurial start-up companies offering inventive new products and services have been named to SLAS Innovation AveNEW at SLAS2014, the Third Annual SLAS Conference and Exhibition, which will be held January 18-22, 2014, at the San Diego Convention Center in San Diego, CA.
The ring-like swirls of dust filling the Andromeda galaxy stand out colorfully in this new image from the Herschel Space Observatory, a European Space Agency mission with important NASA participation. The glow seen here comes from the longer-wavelength, or far, end of the infrared spectrum
A study led by researchers at the University of California, San Diego School of Medicine shines a new light on molecular tools our cells use to govern regulated gene expression. The study was published on line in advance of print November 10 in the journal Nature Structural and Molecular Biology.
Super-typhoon Haiyan, equivalent to a Category 5 hurricane on the U.S. Saffir-Simpson scale, struck the central Philippines municipality of Guiuan at the southern tip of the province of Eastern Samar early Friday morning at 20:45 UTC (4:45 am local time). NASA's TRMM satellite captured visible, microwave and infrared data on the storm.
Scientists discover and describe a new species of scorpion, Euscorpius lycius, coming from the area of ancient Lycia, nowadays the regions of the Muğla and Antalya Provinces in Southwestern Turkey. With the new discovery, the scorpions from this genus found in the country go up to a total of five known species. The study was published in the open access journal ZooKeys.
An international team of high-energy physicists says the discovery of an electrically charged subatomic particle called Zc(4020) is a sign that they have begun to unveil a whole new family of four-quark objects. The Beijing Spectrometer (BESIII) collaboration, which includes scientists from the University of Hawaii at Manoa, previously announced the discovery of a mysterious four-quark particle called Zc(3900)
HPC Source caught up with Rob Farber to talk about OpenACC and the SC13 conference, taking place November 17-22, 2013, in Denver, CO.
Micron Technology announced it is planning to adapt its Hybrid Memory Cube (HMC) for petascale supercomputer systems, representing a dramatic step forward in memory technology. HMC is designed for applications requiring low-energy, high-bandwidth access to memory, which is the most important requirement for supercomputers. Other applications include data packet processing, data packet buffering or storage, and processor acceleration.
By realising an artificial quantum system, physicists at Heidelberg University have simulated key processes of photosynthesis on a quantum level with high spatial and temporal resolution. In their experiment with Rydberg atoms the team of Prof. Dr. Matthias Weidemüller and Dr. Shannon Whitlock discovered new properties of energy transport. This work is an important step towards answering the...
This portrait looking down on Saturn and its rings was created from images obtained by NASA's Cassini spacecraft on October 10, 2013. It was made by amateur image processor and Cassini fan Gordan Ugarkovic. This image has not been geometrically corrected
Using inexpensive materials configured and tuned to capture microwave signals, researchers at Duke University's Pratt School of Engineering have designed a power-harvesting device with efficiency similar to that of modern solar panels. The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device
