Researchers create artificial enzyme that mimics the body's internal engine

...mating the masses of far distant galaxies and thus solved a long-standing astronomical problem. He also discovered that the majority of the most massive galaxies have formed almost no new stars for seven billion years. This finding is at odds with theoretical expectations and has led to a number of new appr...Why some people are more attractive than others
Researchers believe they have solved a mystery that has puzzled evolutionary scientists for years ... if 'good' genes spread through the population, why are individuals so different? The so-called 'lek paradox', that sexually-selecting species like humans should have much less indivi...MIT device draws cells close -- but not too close -- together
...ology (HST) and Brigham and Women's Hospital, have solved the problem with a novel device. The work promises to allow researchers to perform cellular experiments that were previously impossible. Bhatia and HST postdoctoral associate Elliot Hui describe the device in the March 27 online issue of the Proce...First impressions: Computer model behaves like humans on visual categorization task
... the target and ignore the clutter. "We have not solved vision yet," Poggio cautioned, "but this model of immediate recognition may provide the skeleton of a theory of vision. The huge task in front of us is to incorporate into the model the effects of attention and top-down beliefs." The team is now expl...Alternative-fuels pioneer receives first-ever $100,000 Lemelson-MIT Award for Sustainability
...the enzymes act independently of cells. Nature has solved many of the challenges associated with microbial cellulose utilization, which we are gradually discovering, said Lynd. Largely as a result of Lynds efforts, the potential of CBP has been increasingly recognized of late. For example, a recent DOE ro...Halos and horns: Fixing the 'taste' of diet soda
...cts. "We've identified the problem, but we haven't solved it yet. We need to find an ingredient that has no calories but gives the same mouth-feel as sucrose," they said. When science finds that ingredient, the researchers believe diet drinks will be a lot more appealing to people who want to make the swi...Why do oysters choose to live where they could be eaten?
...ers and how larvae actively settle on reefs helped solved the puzzle. Oyster feeding currents are actually very weak, so while they will readily eat larvae if captured, settling larvae are just not captured very often. In fact, when a comparison of being captured versus landing on a suitable location to gro...DNA repair proteins monitored at double-strand break
...D., St. Jude Cancer Center director. "Our approach solved that problem and allowed us to document the cells response to double-strand DNA breaks over time. The technique provides significantly more information about the proteins that repair DNA than is possible using the standard microscope-based approach p...A new wrinkle in evolution -- man-made proteins
...coded in a protein sequence, Chaput and colleagues solved the 3-D crystal structures for their evolutionary optimized protein, termed DX, and the parent sequence. In a surprising result, just two amino acids changes in the protein sequence were found to enhance the binding, solubility and heat stability....Rutgers: GM/GMO/Biotech crop containment strategy

Three years later, his group determined the structure of MreB, a prokaryotic actin-like protein which had been discovered by Jeff Errington. The structural discoveries of FtsZ and MreB proved to be key pieces of evidence for th...Smithsonian scientists show differing patterns of rainforest biodiversity

He noted this kind of study needs to be replicated across a large spatial scale in the Amazon Basin and the Congo Basin to see if the low beta diversity pattern holds. Researchers coll...
