Collaborative research between scientists in the UK and USA has led to a major breakthrough in the understanding of antiferromagnets, published in this week's Nature. Scientists at the London Centre for Nanotechnology, the University of Chicago and the Center for Nanoscale Materials at Argonne National Laboratory have used x-rays to see the internal workings of antiferromagnets for the very first time.

When it comes to studying energy transfer in photosynthesis, it's good to think "outside the bun."

That's what Robert Blankenship, Ph.D., professor of biology and chemistry in Arts & Sciences at Washington University in St. Louis, did when he contributed a protein to a study performed by his collaborators at Lawrence Berkeley National Laboratory and the University of California at Berkeley. The protein's moniker? The taco shell protein.

By monitoring changes in vibrations of bridges it is possible to identify hidden cracks and fractures, according to a Queensland University of Technology researcher.

QUT engineering researcher Henry Shih said variations in bridge vibrations of a bridge could be a telling sign of its structural "health".

Breastfeeding and the good fats in Omega-3 fatty acids help new moms fight depression, according to new review.

The review was authored by Kathleen Kendall-Tackett, a health psychologist and researcher at UNH's Crimes against Children Research Center. Kendall-Tackett presents her findings in the article "A New Paradigm for Depression in New Mothers: The Central Role of Inflammation and How Breastfeeding and Anti-Inflammatory Treatments Protect Maternal Mental Health." The full article is available at http://www.internationalbreastfeedingjournal.com/content/2/1/6.

"Depression in new mothers is common in many cultures, affecting anywhere from 10 percent to 20 percent of postpartum women. In some high-risk populations, the percentage can even be as high as 40 percent or 50 percent.

Engineers at Washington University in St. Louis have developed a unique photocatlytic cell that splits water to produce hydrogen and oxygen in water using sunlight and the power of a nanostructured catalyst.

The group is developing novel methodologies for synthesis of nanostructured films with superior opto-electronic properties. One of the methods, which sandwiches three semiconductor films into a compact structure on the nanoscale range, is smaller, more efficient and more stable than present photocatalytic methods which require multiple steps and can take from several hours to a day to complete.

Screens that not only display images but also generate their own power are on the horizon.

One of the new display technologies will be suitable for cellphones, making their batteries last far longer than they do now. The other could lead to selfpowered electronic billboards.
