Mutations affecting any one of these three proteins can cause congenital muscular dystrophies in humans.

Atomic clock can simulate quantum magnetism Posted: 08 Aug 2013 11:21 AM PDT Researchers have for the first time used an atomic clock as a quantum simulator, mimicking the behavior of a different, more complex quantum system. All but the smallest, most trivial quantum systems are too complicated to simulate on classical computers, hence the interest in quantum simulators to understand the quantum mechanical behavior of exotic materials such as high-temperature superconductors.

Atomic insights into plant growth: How plant steroid hormone makes plants grow Posted: 08 Aug 2013 11:16 AM PDT If one wants to better understand how plants grow, one must analyse the chemistry of life in its molecular detail. Scientists are doing just that. New work reveals that a plant membrane receptor requires a helper protein to sense a growth-promoting steroid hormone and to transduce this signal across the cell membrane.

Gene regulator is key to healthy retinal development and good vision in adulthood Posted: 08 Aug 2013 11:16 AM PDT Scientists are developing a clearer picture of how visual systems develop in mammals. The findings offer important clues to the origin of retinal disorders later in life.

Human activity muddies causes of Texas floods Posted: 08 Aug 2013 11:16 AM PDT Periodic flooding in Texas —- one the most flood-prone states in the U.S. —- cannot be firmly linked to climate change due to numerous dams and other humanmade structures introduced over the years, according to a new article.

Our brains can (unconsciously) save us from temptation Posted: 08 Aug 2013 09:45 AM PDT Inhibitory self control -- not picking up a cigarette, not having a second drink, not spending when we should be saving -- can operate without our awareness or intention.

Way to fight therapy resistant leukemia by blocking DNA repair Posted: 08 Aug 2013 09:45 AM PDT New research suggests blocking part of a DNA repair complex that helps some types of leukemia resist treatment can increase the effectiveness of chemotherapy and enhance survival. Scientists report that their experimental combination treatment strategy -- using a small molecular inhibitor along with chemotherapy -- was particularly effective at stopping a stubborn leukemia called T-cell acute lymphoblastic leukemia.

Ozone hole might slightly warm planet, computer model suggests Posted: 08 Aug 2013 09:45 AM PDT A lot of people mix up the ozone hole and global warming, believing the hole is a major cause of the world's increasing average temperature. Scientists, on the other hand, have long attributed a small cooling effect to the ozone shortage in the hole. Now a new computer-modeling study suggests that the ozone hole might actually have a slight warming influence, but because of its effect on winds, not temperatures. The new research suggests that shifting wind patterns caused by the ozone hole push clouds farther toward the South Pole, reducing the amount of radiation the clouds reflect and possibly causing a bit of warming rather than cooling.

'Digging up' 4-billion-year-old fossil protein structures to reveal how they evolved Posted: 08 Aug 2013 09:38 AM PDT Very little is known about how and when over the course of evolution 3-D protein structures arose. In a new study, researchers resurrected four-billion-year-old Precambrian proteins in the laboratory and gained novel insights into protein evolution by analyzing their X-ray crystal structures. This method has revealed a remarkable degree of structural similarity among proteins since life first evolved on this planet, and represents a powerful and novel approach to explore the evolution of protein structures.

Molecules form 2-D patterns never before observed: Nanoscience experiments produce elusive 5-vertex tilings Posted: 08 Aug 2013 09:38 AM PDT Tessellation patterns that have fascinated mathematicians since Kepler worked out their systematics 400 years ago -- and that more recently have caught the eye of artists and crystallographers -- can now be seen in the laboratory. They first took shape on a surface more perfectly two-dimensional than any sheet of paper, a single layer of atoms and molecules atop an atomically smooth substrate. Physicists coaxed these so-called Kepler tilings "onto the page" through guided self-assembly of nanostructures.

Do fish feel pain? Not as humans do, study suggests Posted: 08 Aug 2013 09:37 AM PDT Fish do not feel pain the way humans do, according to a team of neurobiologists, behavioral ecologists and fishery scientists.
