Computational model simulates bacterial behavior Posted: 27 Mar 2015 11:30 AM PDT |
Posted: 27 Mar 2015 11:30 AM PDT Scientists investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability. On the plateau, ELDs consist of rare mounds, flat-lying deposits, and cross-bedded dune fields. They interpret the mounds as smaller spring deposits, the flat-lying deposits as playa, and the cross-bedded dune fields as aeolian. They write that groundwater fluctuations appear to be the major factor controlling ELD deposition. |

Nanoscale worms provide new route to nano-necklace structures Posted: 27 Mar 2015 11:30 AM PDT Researchers have developed a novel technique for crafting nanometer-scale necklaces based on tiny star-like structures threaded onto a polymeric backbone. The technique could provide a new way to produce hybrid organic-inorganic shish kebab structures from semiconducting, magnetic, ferroelectric and other materials that may afford useful nanoscale properties. |
For drivers with telescopic lenses, driving experience and training affect road test results Posted: 27 Mar 2015 11:30 AM PDT |
Study provides evidence against the fetal origins of cancer, cardiovascular disease Posted: 27 Mar 2015 10:22 AM PDT A study evaluated the relationship between nutritional conditions in early life and adult health, and found that famine exposure during the first pregnancy trimester was associated with increases in mortality from causes other than cancer or cardiovascular disease. This is the first study to quantify the possible long-term effects of nutrition deprivation at different stages of pregnancy and long-term mortality. |

Mira Supercomputer use to Peer Inside High-Temperature Superconductors Posted: 27 Mar 2015 10:21 AM PDT |
New lobster-like predator found in 508 million-year-old fossil-rich site Posted: 27 Mar 2015 09:05 AM PDT What do butterflies, spiders and lobsters have in common? They are all surviving relatives of a newly identified species called Yawunik kootenayi, a marine creature with two pairs of eyes and prominent grasping appendages that lived as much as 508 million years ago -- more than 250 million years before the first dinosaur. |
Is painful knee and hand osteoarthritis in women associated with excess mortality? Posted: 27 Mar 2015 09:05 AM PDT |
Long-standing mystery in membrane traffic solved Posted: 27 Mar 2015 08:18 AM PDT In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. SNARE proteins are known as the minimal machinery for membrane fusion. Scientists now report that NSF/?-SNAP disassemble a single SNARE complex using various single-molecule biophysical methods that allow them to monitor and manipulate individual protein complexes. |
Metals used in high-tech products face future supply risks Posted: 27 Mar 2015 08:18 AM PDT Researchers have assessed the 'criticality' of all 62 metals on the Periodic Table of Elements, providing key insights into which materials might become more difficult to find in the coming decades, which ones will exact the highest environmental costs -- and which ones simply cannot be replaced as components of vital technologies. |
A peek at the secret life of pandas Posted: 27 Mar 2015 08:18 AM PDT The world is fascinated by the reclusive giant pandas, yet precious little is known about how they spend their time in the Chinese bamboo forests. Until now. A team of researchers who have been electronically stalking five pandas in the wild, courtesy of rare GPS collars, have finished crunching months of data and has published some panda surprises. |

Color of lettuce determines the speed of its antioxidant effect Posted: 27 Mar 2015 07:11 AM PDT Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. The color of the leaves of these vegetables determines the speed at which their compounds act. So lettuces with green leaves have antioxidants that react more slowly while red-leaf ones have a faster effect. |

Computer programming: Internet of things should be developable for all Posted: 27 Mar 2015 06:18 AM PDT Within the next five to ten years, around 100 billion different devices will be online. A large part of the communication takes place solely between machines, and to ensure that they can communicate, the European Commission has supported a project that over the last three years has been working on creating a common platform – a programming language, that can make everything from microwave ovens to wind meters talk to each other. |
The stapes in the middle ear of a Neanderthal child shows anatomical differences from humans Posted: 27 Mar 2015 06:18 AM PDT Scientists have produced a 3-D reconstruction of the remains of a two-year-old Neanderthal recovered from an excavation carried out back in the 1970s at La Ferrassie (Dordogne, France). The work reveals the existence of anatomical differences between the Neanderthals and our species, even in the smallest ossicles of the human body. |
Two degree Celsius climate change target 'utterly inadequate', expert argues Posted: 27 Mar 2015 06:10 AM PDT The official global target of a two degree Celsius temperature rise is 'utterly inadequate' for protecting those at most risk from climate change, says an expert. The commentary presents a rare inside-view of a discussion at the Lima Conference of the Parties on the likely consequences of accepting an average global warming target of 2 degrees Celsius versus 1.5 degrees Celsius. |

Bio-marker set forms the basis for new blood test to detect colorectal cancer Posted: 27 Mar 2015 06:09 AM PDT Colorectal cancer is the third most common form of cancer globally and the second most common cause of cancer deaths. The chance of a cure is high if the cancer is detected early enough, but early detection is not a given. Researchers have identified bio-markers that can be incorporated in a new diagnostic test. This should make it possible to detect colorectal cancer in an early stage using a simple blood test, they say. |
Greener industry if environmental authorities change strategy Posted: 27 Mar 2015 06:09 AM PDT Fewer industrial firms would violate environmental legislation and a higher number would adopt cleaner technologies if environmental authorities would focus their monitoring efforts on companies with the most environmentally damaging technology. At a societal level, such a strategy would mean less pollution at the same or a lower cost of monitoring, according to new research. |
Novel coatings combine protection with color effects Posted: 27 Mar 2015 06:09 AM PDT |
Posted: 27 Mar 2015 06:09 AM PDT Although music perception and practice are well preserved in human evolution, the biological determinants of music practice are largely unknown. According to a latest study, music performance by professional musicians enhanced the activity of genes involved in dopaminergic neurotransmission, motor behavior, learning and memory. Interestingly, several of those up-regulated genes were also known to be responsible for song production in songbirds, which suggests a potential evolutionary conservation in sound perception and production across species. |
Evolutionary novelties in vision Posted: 27 Mar 2015 06:09 AM PDT |
High-precision radar for the steel industry Posted: 27 Mar 2015 06:08 AM PDT Steel is the most important material in vehicle and machinery construction. Large quantities of offcuts and scraps are left over from rolling and milling crude steel into strip steel. New radar measures the width of the strip during fabrication to an accuracy of micrometers and helps to minimize scrap. |
Virtual vehicle testing: Modeling tires realistically Posted: 27 Mar 2015 06:07 AM PDT Manufacturers conduct virtual tests on vehicle designs long before the first car rolls off the assembly line. Simulation of the tires has remained a challenge, however. The software tool "CDTire/3D" now models the wheels realistically. The software takes into account the heat that is generated during driving and how the properties of the tires change. |
Research on medical abortion, miscarriage may change international routines Posted: 27 Mar 2015 06:07 AM PDT Two scientific studies are expected to form the basis of new international recommendations for the treatment of medical abortions and miscarriages. One of the studies shows that it is possible to replace the clinical follow-up examinations recommended today with medical abortions that include a home pregnancy test. The other study shows that midwives can safely and effectively treat failed abortions and miscarriages in rural districts of Uganda. |

Big data allows computer engineers to find genetic clues in humans Posted: 27 Mar 2015 06:06 AM PDT |
MRI based on a sugar molecule can tell cancerous from noncancerous cells Posted: 27 Mar 2015 06:06 AM PDT Imaging tests like mammograms or CT scans can detect tumors, but figuring out whether a growth is or isn't cancer usually requires a biopsy to study cells directly. Now results of a study suggest that MRI could one day make biopsies more effective or even replace them altogether by noninvasively detecting telltale sugar molecules shed by the outer membranes of cancerous cells. |
First fully-implantable micropacemaker designed for fetal use Posted: 26 Mar 2015 05:46 PM PDT |
Weight-loss surgery before joint replacement can improve outcomes in severely overweight patients Posted: 26 Mar 2015 05:46 PM PDT Bariatric surgery prior to joint replacement is a cost-effective option to improve outcomes in severely overweight patients, research demonstrates. It is well-known that obesity takes a toll on one's health. Bariatric surgery and subsequent weight loss reduces the risk of heart disease, diabetes and even some forms of cancer. But before now, the effect of bariatric surgery on joint replacement outcomes was not known. |

What to do with kidneys from older deceased donors? Posted: 26 Mar 2015 03:35 PM PDT For older patients in need of a kidney transplant, rapid transplantation from an older deceased donor is superior to delayed transplantation from a younger donor. Kidneys from older donors do not have sufficient longevity to provide younger patients with a lifetime of kidney function, but they do have sufficient longevity to provide older patients who have a shorter life expectancy with a lifetime of kidney function. |
Genetic mutation helps explain why, in rare cases, flu can kill Posted: 26 Mar 2015 01:27 PM PDT A small number of children who catch the influenza virus fall so ill they end up in the hospital even while their family and friends recover easily. New research helps explain why: a rare genetic mutation that prevents the production of a critical protein, interferon, that is needed to fight off the virus. |
