Super predators and mass extinctions; extreme NMR; and the world's smallest solenoids

...se the nuclei to flip over and create signals that reveal information about the atoms and their environments. This makes NMR spectroscopy an important method for analyzing chemical composition and molecular structure. NMR is also the phenomenon at the heart of Magnetic Resonance Imaging (MRI), one of the m...

Navigating an integrated yeast network

...l Journal of Biology shows that such maps can also reveal cryptic interactions and enable accurate predictions about interactions that haven't been observed experimentally. A living cell contains thousands of proteins, genes and macromolecules, enmeshed in complex webs of relationships involving direct or i...

DOE JGI sequences DNA from extinct cave bear

...back in time through the vehicle DNA sequencing to reveal the story of other extinct species including our nearest relatives, the Neandertals. Until now, researchers have been stymied in attempts to sequence genomes of extinct species. The DOE JGI scientists overcame many of the difficulties normally associ...

Scientists create digital bacteria to forge advances in biomedical research

...niel Koshland in 1976," Emonet said. They may even reveal why cells sometimes act as individuals and sometimes as part of a community. AgentCell was made possible by agent-based software, which researchers developed to simulate stock markets, social behavior and warfare. Argonne's Macal and North contribut...

Ancient DNA confirms single origin of Malagasy primates

...he bones and teeth from which the DNA was obtained reveal that each of the individuals analyzed died well over 1,000 years ago, according to the senior author, Anne Yoder, associate professor in the Department of Ecology and Evolutionary Biology. Living lemurs comprise more than 50 species, all of which are...

Initial data show that using low-density sequencing for such comparisons is almost as effective as more costly, high-density sequencing. The eight mammals are: the 13-lined ground squirrel (Spermophil...

Researchers get first peek at amyloid's spine

...he human version of "mad cow" disease. The images reveal that the filaments form a short zipper that is closed and stuck. To get a more realistic picture of what the fibrils look like, however, one should picture a towering stack of zippers, each of which is tightly bonded to the one below. The first atom...

Scientists devise way to measure RNA synthesis on the fly in a live cell

...ew technique will now facilitate research that may reveal how RNA molecules, like proteins, turn genes on and off, Cluzel said....

World first: Scientists succeed in cloning human embryos from eggs matured in the lab

...o the blastocyst stage, and failure to do so could reveal some problems in gene activation, especially in cloned embryos. So, first we have to understand how to get cloned blastocysts of good quality from in vitro matured oocytes. This will be difficult because it is well known that embryonic development ...

Scientists create artificial cricket hairs

...hey have also obtained experimental results, which reveal how good these artificial cricket hairs are at sensing low-frequency sound. The work was carried out by the MESA+ research institute at the University of Twente, as part of the European Union project CICADA (Cricket Inspired perCeption and Autonomou...

Ultra-fast camera captures how hummingbirds hover

... motion analysis alone was not sufficient to fully reveal the underlying aerodynamics. In this study, the researchers applied "digital particle imaging velocimetry" (DPIV) to follow the flapping wings. DPIV is used in various applications to study flow characteristics of liquids and gases. By taking picture...

NASA probe could reveal comet life, scientists claim

...r role in a NASA mission, which they believe could reveal living matter in the icy layers beneath the surface of a comet. NASA's Deep Impact spacecraft will make a historic encounter with Comet Tempel-1 on 4th July, when a metre-long projectile will crash into the comet and tunnel through its outer layers, ...

New model for studying species distributions and the mid-domain effect developed

... compared to randomization analyses. These results reveal that the mid-domain effect is likely to be a real phenomenon, and thus cannot be ignored, but that comparing real biodiversity patterns to those produced by randomizations may be misleading. They also identify an alternative way forward: formulating ...

Meaningless sex? Male mounting reduces sexual promiscuity of females

...or, researchers have utilized a novel technique to reveal that in feral chickens, the simple stimulus generated by male mounting--in the absence of actual insemination--reduces the sexual promiscuity of a hen, indicating that even copulations that do not result in semen transfer may be crucial to defend the...
