Lights out… light pollution alters reproduction cycle in lemurs Posted: 02 Jul 2014 05:38 PM PDT |
Posted: 02 Jul 2014 05:37 PM PDT Type 2 diabetes is usually controlled by diet and medication, but most people with advanced disease also end up needing insulin therapy to achieve control of their blood sugar. However, roughly a third of these patients struggle to achieve the right level of blood sugar control with insulin injections many times a day. The growing obesity epidemic is adding to the problem by leading to greater insulin resistance. |

Polyphenols could yield small benefit for people with PAD Posted: 02 Jul 2014 02:00 PM PDT |
Ocean on Saturn's moon Titan could be as salty as Earth's Dead Sea Posted: 02 Jul 2014 01:55 PM PDT Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as Earth's Dead Sea. The new results come from a study of gravity and topography data collected during Cassini's repeated flybys of Titan during the past 10 years. Using the Cassini data, researchers presented a model structure for Titan, resulting in an improved understanding of the structure of the moon's outer ice shell. |
Black hole fireworks in nearby galaxy Posted: 02 Jul 2014 01:53 PM PDT Celebrants this Fourth of July will enjoy the dazzling lights and booming shock waves from the explosions of fireworks. A similarly styled event is taking place in the galaxy Messier 106, as seen by NASA's Spitzer Space Telescope, Chandra X-ray Observatory and the Herschel Space Observatory. Herschel is a European Space Agency mission with important NASA contributions. |
Noninvasive advanced image analysis could lead to better patient care Posted: 02 Jul 2014 12:39 PM PDT Lung cancer patients could receive more precise treatment, and their progress could be better tracked, using a new high-tech method of non-invasive medical imaging analysis, according to a study. Genetic changes increasingly are recognized as driving cancer development. But obtaining evidence of these changes usually requires a biopsy, which can be problematic for sensitive regions of the body such as the lungs. |

Hair from mummy's clothes provides insights into red deer lineage Posted: 02 Jul 2014 12:14 PM PDT |
New species of spider wasp may use chemical signals from dead ants to protect nest Posted: 02 Jul 2014 12:14 PM PDT |
Major gaps in hepatitis C care identified as new drugs, screening efforts emerge Posted: 02 Jul 2014 12:13 PM PDT Significant gaps in hepatitis C care identified in a new meta-analysis will prove useful as the U.S. health care system continues to see an influx of patients with the disease because of improved screening efforts and new, promising drugs. In the largest study of its kind, the team examined data culled from 10 studies between 2003 and 2013 and found that less than 10 percent of people infected with hepatitis C in the United States -- 330,000 of nearly 3.5 million people -- were cured (achieved viral suppression) with antiviral hepatitis C treatment. |
Die-offs of band-tailed pigeons connected to newly discovered parasite Posted: 02 Jul 2014 11:06 AM PDT A new parasite, along with one possibly found in T-Rex, has been implicated in the recent deaths of thousands of Pacific Coast band-tailed pigeons. Avian trichomonosis is an emerging and potentially fatal disease that creates severe lesions that can block the esophagus, ultimately preventing the bird from eating or drinking, or the trachea, leading to suffocation. The disease may date back to when dinosaurs roamed the earth, as lesions indicative of trichomonosis were found recently in T-Rex skeletons. |
Researchers regrow corneas, first known tissue grown from an adult human stem cell Posted: 02 Jul 2014 10:17 AM PDT Researchers have identified a way to enhance regrowth of human corneal tissue to restore vision, using a molecule known as ABCB5 that acts as a marker for hard-to-find limbal stem cells. The research is also one of the first known examples of constructing a tissue from an adult-derived human stem cell. |
Extinct human cousin gave Tibetans advantage at high elevation Posted: 02 Jul 2014 10:17 AM PDT Several thousand years ago, the common ancestors of Han Chinese and Tibetans moved onto the Tibetan plateau, a low-oxygen environment that probably proved fatal to many because of early heart disease and high infant mortality. But a specific variant of a gene for hemoglobin regulation, picked up from earlier interbreeding with a mysterious human-like species, Denisovans, gradually spread through the Tibetan population, allowing them to live longer and healthier and avoid cardiovascular problems. |
Hollow optical fibers for UV light Posted: 02 Jul 2014 10:16 AM PDT If you want to send light on a trip through optical fibers -- with as little loss as possible, you should opt for infrared light, as is the case, for example, in the telecommunication networks worldwide. For certain applications, such as spectroscopic investigations on ions or atoms, however, (laser) light in the ultraviolet range is required. But this type of light would quickly damage conventional optical fibers. Researchers have now tested a new type of optical fiber with a hollow core and have found out that this type of optical fiber was able to guide UV laser light without being damaged and with acceptable loss. |
Martian salts must touch ice to make liquid water, study shows Posted: 02 Jul 2014 10:16 AM PDT In chambers that mimic Mars' conditions, researchers have shown how small amounts of liquid water could form on the planet despite its below-freezing temperatures. Liquid water is an essential ingredient for life as we know it. Mars is one of the very few places in the solar system where scientists have seen promising signs of it -- in gullies down crater rims, in instrument readings, and in Phoenix spacecraft self portraits that appeared to show wet beads on the lander's leg several years ago. |
Who will binge-drink at age 16? Teen imaging study pinpoints predictors Posted: 02 Jul 2014 10:16 AM PDT |
Boron tolerance discovery for higher wheat yields Posted: 02 Jul 2014 10:16 AM PDT The genes in wheat that control tolerance to a significant yield-limiting soil condition found around the globe – boron toxicity -- have been identified by researchers. They say that in soils where boron toxicity is reducing yields, genetic improvement of crops is the only effective strategy to address the problem. |
New reprogramming method makes better stem cells Posted: 02 Jul 2014 10:16 AM PDT |
A case study of manta rays and lagoons Posted: 02 Jul 2014 09:25 AM PDT Doug McCauley chose one of the most isolated places in the world, Palmyra Atoll, to study the ecology of the Manta alfredi. About halfway between Hawaii and American Samoa, this complex of small islands and inlets in the central Pacific is surrounded by more than 15,000 acres of coral reefs and encircles three lagoons. |
Stem cell type resists chemotherapy drug Posted: 02 Jul 2014 09:25 AM PDT Adipose-derived stem cells, which can generate bone tissue, appear resistant to the toxicity of the chemotherapy drug methotrexate, which degrades bone in patients such as kids suffering from acute lymphoblastic leukemia, researchers have found. The newly published findings are preliminary but more tests are planned. |
Antibiotic therapy reduces mortality by 68 percent in hemodialysis patients Posted: 02 Jul 2014 09:25 AM PDT |
Causes of serious pain syndrome closer to discovery Posted: 02 Jul 2014 09:25 AM PDT A major step forward has been made in understanding the causes of a disorder which causes chronic pain in sufferers. Complex Regional Pain Syndrome (CRPS) is a serious condition affecting a limb after an -- often small -- accident or operation. It can cause severe pain lasting many years, as well as limb swelling, hair and nail growth changes, and muscle atrophy, but until now there has been no clear evidence of the cause. |
Twin study links community socioeconomic deprivation to sleep duration Posted: 02 Jul 2014 09:24 AM PDT A new study of adult twins suggests that the level of socioeconomic deprivation in a neighborhood is associated with the sleep duration of residents. "The more socioeconomically deprived the neighborhood, the more erratic the sleep duration, both shorter and longer than the healthy seven to nine hours per night that we recommend," researchers said. |

Fruit fly research may reveal what happens in female brains during courtship, mating Posted: 02 Jul 2014 09:24 AM PDT |
Deforestation remedies can have unintended consequences Posted: 02 Jul 2014 09:22 AM PDT When it comes to fixing deforestation and forest degradation, good intentions can lead to bad outcomes. Among other points, researchers note that even when there's technically no net deforestation, tropical forests can still suffer. For example, if degraded natural forests are replaced by plantations of invasive exotic trees or low water-use efficiency trees, biodiversity will diminish, wildlife could suffer and soil erosion could render streams unusable by local villagers. |
'Lost in translation' issues in Chinese medicine addressed by researchers Posted: 02 Jul 2014 09:22 AM PDT Millions of people in the West today utilize traditional Chinese medicine, including acupuncture, herbs and massage therapies. Yet only a handful of Chinese medical texts have so far been translated into English. Given the complexity of the language and concepts, there is a need for accurate, high-quality translations. Researchers have published a document designed to help evaluate and digest Chinese medical texts with greater sensitivity and comprehension. |
Posted: 02 Jul 2014 09:22 AM PDT A protein essential to regulating cell cycle progression – the process of cell division and replication – activates a key tumor suppressor, rather than inactivating it as previously thought, researchers report. The findings fundamentally change the understanding of G1 cell cycle regulation and the molecular origins of many associated cancers. |
Process that affects fat distribution, metabolic syndrome found by researchers Posted: 02 Jul 2014 08:10 AM PDT |
Becoming an expert takes more than practice Posted: 02 Jul 2014 08:10 AM PDT |
Overcoming light scattering: New optical system sees deeper inside tissue Posted: 02 Jul 2014 08:10 AM PDT Optical imaging could become even more valuable if researchers could find a way for light to penetrate all the way through the body's tissues. Currently, passing through a fraction of an inch of skin is enough to scatter the light and scramble the image. Now researchers have developed a single-pixel optical system based on compressive sensing that can overcome the fundamental limitations imposed by this scattering. |
Toward a new way to keep electronics from overheating Posted: 02 Jul 2014 08:10 AM PDT Computer technology has transformed the way we live, but as consumers expect ever more from their devices at faster speeds, personal computers as well as larger electronic systems can overheat. This can cause them to slow down, or worse, completely shut down. Now researchers are reporting that liquids containing nanoparticles could help devices stay cool and keep them running. |
Squid sucker ring teeth material could aid reconstructive surgery, serve as eco-packaging Posted: 02 Jul 2014 08:10 AM PDT Squid tentacles are loaded with hundreds of suction cups, or suckers, and each sucker has a ring of razor-sharp 'teeth' that help these mighty predators latch onto and take down prey. Researchers report that the proteins in these teeth could form the basis for a new generation of strong, but malleable, materials that could someday be used for reconstructive surgery, eco-friendly packaging and many other applications. |
Putting a price tag on the 2 degree Celsius climate target Posted: 02 Jul 2014 08:10 AM PDT Addressing climate change will require substantial new investment in low-carbon energy and energy efficiency -- but no more than what is currently spent on today's fossil-dominated energy system, according to new research. To limit climate change to 2 degrees Celsius, low-carbon energy options will need additional investments of about US $800 billion a year globally from now to mid-century, according to a new study. |
Posted: 02 Jul 2014 08:09 AM PDT Ancient Japanese gold leaf artists were truly masters of their craft. An analysis of six ancient Namban paper screens show that these artifacts are gilded with gold leaf that was hand-beaten to the nanometer scale. Researchers believe that the X-ray fluorescence technique they used in the analysis could also be used to date other artworks without causing any damage to them. |

NASA launches carbon mission to watch Earth breathe Posted: 02 Jul 2014 07:30 AM PDT NASA successfully launched its first spacecraft dedicated to studying atmospheric carbon dioxide on July 1, 2014. OCO-2 soon will begin a minimum two-year mission to locate Earth's sources of and storage places for atmospheric carbon dioxide, the leading human-produced greenhouse gas responsible for warming our world, and a critical component of the planet's carbon cycle. |
3-D printer to aid the visually impaired students in their educational endeavors Posted: 02 Jul 2014 07:26 AM PDT New technology has been developed to make tactile objects with ease thanks to the convergence technology of 3-D printing and 3-D thermal reflow treatment, which can be denoted as the revolution in manufacturing technology. Using the technology, not only braille books, but also braille picture books and teaching materials can be made with greater flexibility in color, height and size. It is also harmless to human body since it does not require UV coating or harmful chemical treatment. |
Socioeconomic status associated with peripheral artery disease risk Posted: 02 Jul 2014 07:24 AM PDT Previous research has established a link between lower socioeconomic status and an increased risk of cardiovascular disease. In a new study, researchers have found that there are also higher rates of peripheral artery disease in individuals with low income and lower attained education levels in the United States. |
New approach for tuberculosis drugs Posted: 02 Jul 2014 07:24 AM PDT In the past 50 years, only one new tuberculosis drug has come on to the market, yet many more active substances are urgently needed. Current treatments increasingly fail due to multidrug-resistant pathogens. Researchers have now applied to patent a novel approach for developing new tuberculosis drugs. |
Posted: 02 Jul 2014 07:24 AM PDT Graphene is gaining heated attention, dubbed a "wonder material" with great conductivity, flexibility and durability. However, graphene is hard to come by due to the fact that its manufacturing process is complicated and mass production has not been possible. A carbon material has now been developed without artificial defects commonly found during the production process of graphene while maintaining its original characteristics. |
Testosterone therapy does not increase heart attack risk, study shows Posted: 02 Jul 2014 07:24 AM PDT Testosterone prescriptions for older men in the United States have increased more than three-fold over the past decade. Recent studies linking testosterone use with increased risk of heart attack and stroke have caused widespread concern among patients and their families. A new US-based study of more than 25,000 older men shows that testosterone therapy does not increase men's risk for heart attack. |
Four in 10 pancreatic cancers could be prevented by lifestyle changes Posted: 02 Jul 2014 07:23 AM PDT Almost 40 per cent of pancreatic cancers -- one of the deadliest forms of cancer -- could be avoided through maintaining a healthy weight and not smoking according to research, in a call to arms against the disease. While more research is needed to find better ways of diagnosing and treating the disease, there is evidence to suggest that some pancreatic cancers are linked to being overweight and to smoking -- and almost four in 10 could be prevented by lifestyle changes to address this. |
One of world's thinnest piezoelectric materials identified Posted: 02 Jul 2014 06:36 AM PDT There are a handful of naturally occurring materials, known as piezoelectric materials, that generate electricity if you bend, stretch or apply another mechanical force to them, and vice versa -- if you apply a voltage across them, they'll deform accordingly. These materials are currently the subject of intense research for their potential applications in energy harvesting, artificial muscles and sensors, among others. These materials are also used in everyday devices, such as loudspeakers, which rely on piezoelectrics to convert electrical signals to mechanical vibrations which create sound waves to produce the desired acoustic signal. Mechanical engineers have now identified one of the thinnest possible piezoelectric materials on the planet -- graphene nitride. |

Reinterpreting dark matter: Could dark matter be regarded as a very cold quantum fluid? Posted: 02 Jul 2014 06:23 AM PDT Astronomers have explored cold dark matter in depth and proposes new answers about the formation of galaxies and the structure of the Universe. These predictions are being contrasted with fresh data provided by the Hubble space telescope. It is estimated that only a minute fraction of the matter in the Universe is baryonic matter, which forms stars, planets and living organisms. The rest, comprising over 80%, is dark matter and energy. |

How does your garden grow? 3-D root imaging in real time Posted: 01 Jul 2014 04:32 PM PDT Growing plants in a microscope is helping scientists to view roots developing in 3-D and in real time. Scientists already know that lateral roots in plants develop from cells deep within the main root, so that the emerging roots must force through multiple layers of tissue to reach the soil. Until now, capturing the cell-division events behind this process has proved exceptionally difficult. |
A sheep's early life experiences can shape behavior in later life Posted: 01 Jul 2014 04:32 PM PDT New research has found that a sheep's experiences soon after birth can shape its later behavior and also that of its offspring. Scientists investigated whether early-life experiences can alter behavioral responses to a naturally painful event in adulthood -- giving birth -- and also affect behavior of the next generation. |
