| More Earthquakes for Chile? Seismic gap has not been closed Posted: 04 Apr 2014 11:00 AM PDT After the strong earthquake that struck Chile on April 2 (CEST), numerous aftershocks, some of them of a considerable magnitude, have struck the region around Iquique. Seismologists doubt that the strong earthquake closed the local seismic gap and decreased the risk of a large earthquake. On the contrary, initial studies of the rupture process and the aftershocks show that only about a third of the vulnerable zone broke.  |

- Low-dose aspirin won't prevent pregnancy loss, study shows
- Young motorists lack self control
- Still no clear evidence for health benefits of vitamin D? Experts try to make sense of the data
| Low-dose aspirin won't prevent pregnancy loss, study shows Posted: 04 Apr 2014 12:16 PM PDT Low-dose aspirin, in general, is not beneficial for future pregnancy outcomes in women with prior pregnancy loss, a medical trial has found. However, in women with one pregnancy loss within the previous 12 months, there did appear to be a benefit. Many health care providers prescribe low-dose aspirin therapy for women who have had a pregnancy loss, and who would like to get pregnant again, the researchers noted.  |
| Young motorists lack self control Posted: 04 Apr 2014 05:55 AM PDT So now we have it in black and white -- the emotional center in young men's brains overrides the area controlling their ability to make rational decisions. This leads to accidents among risk-seeking motorists. Last autumn thirty-four young people allowed their brains to be scanned while playing car race video games. The aim was to win. But the speeds were fixed and subjects only had the use of a start and stop button. A scanner recorded the activity in their young brains throughout.  |
| Still no clear evidence for health benefits of vitamin D? Experts try to make sense of the data Posted: 01 Apr 2014 06:04 PM PDT Despite a huge number of studies into the role of vitamin D on health, there is still no clear evidence that it has a beneficial effect on many conditions, conclude researchers. A growing body of evidence indicates that vitamin D may reduce risks of a wide range of diseases, including bone mineral disease, multiple sclerosis, autoimmune disorders, cancer and cardiovascular problems. Yet, despite hundreds of trials, the evidence for vitamin D is still being debated.  |

| Off the shelf, on the skin: Stick-on electronic patches for health monitoring Posted: 03 Apr 2014 06:26 PM PDT Wearing a fitness tracker on your wrist or clipped to your belt is so 2013. Engineers have demonstrated thin, soft stick-on patches that stretch and move with the skin and incorporate off-the-shelf electronics for sophisticated wireless health monitoring. The patches stick to the skin like a temporary tattoo and incorporate a unique microfluidic construction with wires folded like origami to allow the patch to bend and flex.  |
| Monster 'El Gordo' galaxy cluster is bigger than thought Posted: 03 Apr 2014 11:18 AM PDT Astronomers have weighed the largest known galaxy cluster in the distant universe and found that it definitely lives up to its nickname: El Gordo (Spanish for "the fat one"). By precisely measuring how much the gravity from the cluster's mass warps images of far-more-distant background galaxies, a team of astronomers has calculated the cluster's mass to be as much as 3 million billion times the mass of our Sun. The Hubble data show that the cluster is roughly 43 percent more massive than earlier estimates based on X-ray and dynamical studies of the unusual cluster.  |
| Energy breakthrough uses sun to create solar energy materials Posted: 03 Apr 2014 10:23 AM PDT Researchers have discovered a way to tap the sun not only as a source of power, but also to directly produce the solar energy materials that make this possible. This breakthrough could make the sun almost a 'one-stop shop' that produces both the materials for solar devices and the eternal energy to power them.  |
| Hummingbirds' 22-million-year-old history of remarkable change is far from complete Posted: 03 Apr 2014 10:22 AM PDT The first comprehensive map of hummingbirds' 22-million-year-old family tree -- reconstructed based on careful analysis of 284 of the world's 338 known species -- tells a story of rapid and ongoing diversification. The decade-long study also helps to explain how today's hummingbirds came to live where they do.  |
| Running, cardio activities in young adulthood may preserve thinking skills in middle age Posted: 02 Apr 2014 01:23 PM PDT Young adults who run or participate in other cardio fitness activities may preserve their memory and thinking skills in middle age, according to a new study. Middle age was defined as ages 43 to 55 in this study. "These findings are likely to help us earlier identify and consequently prevent or treat those at high risk of developing dementia," researchers said.  |
| New general concept for treatment of cancer Posted: 02 Apr 2014 10:39 AM PDT A team of researchers from five Swedish universities has identified a new way of treating cancer. The concept is based on inhibiting a specific enzyme called MTH1, which cancer cells, unlike normal cells, require for survival. Without this enzyme, oxidized nucleotides are incorporated into DNA, resulting in lethal DNA double-strand breaks in cancer cells.  |
| Poor sleep quality linked to cognitive decline in older men Posted: 31 Mar 2014 02:05 PM PDT A link between poor sleep quality and the development of cognitive decline over three to four years was found in a new study of older men. Results show that higher levels of fragmented sleep and lower sleep efficiency were associated with a 40 to 50 percent increase in the odds of clinically significant decline in executive function, which was similar in magnitude to the effect of a five-year increase in age. In contrast, sleep duration was not related to subsequent cognitive decline.  |

- Inspired by moth eyeballs, chemists develop gold coating that dims glare
- Watching for a black hole to gobble up a gas cloud: Gas cloud's fate illuminates growth of supermassive black holes
- Don't move a mussel (or a clam, or a snail)
| Inspired by moth eyeballs, chemists develop gold coating that dims glare Posted: 04 Apr 2014 11:04 AM PDT All that's gold does not glitter, thanks to new work that could reduce glare from solar panels and electronic displays and dull dangerous glints on military weapons.  |
| Posted: 04 Apr 2014 05:58 AM PDT G2, a doomed gas cloud, is edging closer to Sgr A*, the hungry supermassive black hole at the Milky Way's center. The closest approach between the two is predicted to occur any day now. Astrophysicists have been watching closely, and the data do not show enhanced emission in the X-rays.  |
| Don't move a mussel (or a clam, or a snail) Posted: 02 Apr 2014 10:39 AM PDT Anyone that has spent time at a seaside pier has witnessed the destruction barnacles wreak on boat hulls. But biofouling animals are not limited to marine environments. A new paper estimates that the global management of freshwater mussels, clams, and other clinging animals costs $277 million US dollars annually.  |

- Antioxidants can protect against omega 6 damage -- or promote it
- Light-activated neurons from stem cells restore function to paralyzed muscles
- Higher total folate intake may be associated with lower risk of exfoliation glaucoma
| Antioxidants can protect against omega 6 damage -- or promote it Posted: 04 Apr 2014 11:03 AM PDT Given omega 6 fatty acid's reputation for promoting cancer -- at least in animal studies -- researchers are examining the role that antioxidants play in blocking the harmful effects of this culprit, found in many cooking oils. After all, antioxidants are supposed to prevent DNA damage. But employing antioxidants could backfire, say researchers.  |
| Light-activated neurons from stem cells restore function to paralyzed muscles Posted: 04 Apr 2014 11:03 AM PDT A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by adjusting the intensity, duration and frequency of the light pulses.  |
| Higher total folate intake may be associated with lower risk of exfoliation glaucoma Posted: 03 Apr 2014 06:25 PM PDT Researchers observed that higher total folate intake was associated with a lower risk for exfoliation glaucoma/suspected exfoliation glaucoma (SEG), supporting a possible causal role of homocysteine in EG/SEG. Elevated homocysteine, which may enhance exfoliation material formation, is one possible risk factor that has received significant research attention. Research studies demonstrate that high intake of vitamin B6, vitamin B12 and folate is associated with lower homocysteine levels.  |

| Work with small peptide chains may revolutionize study of enzymes, diseases Posted: 04 Apr 2014 11:04 AM PDT Chemists, for the first time, have created enzyme-like activity using peptides that are only seven amino acids long. The breakthrough may revolutionize the study of modern-day enzymes, whose chains of amino acids usually number in the hundreds, and of neurological diseases, such as Alzheimer's, which are usually characterized by small clumps of misshapen proteins called amyloids.  |
| Depression increases heart failure risk by 40 percent Posted: 04 Apr 2014 11:02 AM PDT Moderate to severe depression increases the risk of heart failure by 40 percent, a study of nearly 63,000 Norwegians has shown. During the study period nearly 1,500 people developed heart failure. Compared to residents with no symptoms of depression, people with mild symptoms had a 5% increased risk of developing heart failure and those with moderate to severe symptoms had a 40% increased risk.  |
| Poor quality of life may contribute to kidney disease patients' health problems Posted: 03 Apr 2014 06:23 PM PDT In African American patients with chronic kidney disease, poor quality of life was linked with increased risks of disease progression and heart problems. Approximately 60 million people globally have chronic kidney disease (CKD). Quality of life has been well-studied in patients with end-stage kidney disease, but not in patients with CKD who do not yet require dialysis.  |
| Surgeons use cyberknife to treat vocal cord cancer Posted: 03 Apr 2014 10:19 AM PDT Stephen Wiley, a lifelong cowboy from Terrell, has helped pioneer a new treatment for vocal cord cancer. Doctors found tumors in both his vocal cords. The $7 million Cyberknife, has a small linear particle accelerator and a robotic arm that allows it to treat tumors on any part of the body with radiation, explained his surgeon. Only about 200 of these cutting-edge machines exist in the world, most of them in the United States.  |

| Scientists unmask the climate uncertainty monster Posted: 04 Apr 2014 11:03 AM PDT Increasing uncertainty in the climate system compels a greater urgency for climate change mitigation, according to new research. Scientists have shown that as uncertainty in the temperature increase expected with a doubling of carbon dioxide from pre-industrial levels rises, so do the economic damages of increased climate change. Greater uncertainty also increases the likelihood of exceeding 'safe' temperature limits and the probability of failing to reach mitigation targets. The authors highlight this with the case of future sea level, as larger uncertainty in sea level rise requires greater precautionary action to manage flood risk.  |
| Combining cell replication blocker with common cancer drug kills resistant tumor cells Posted: 04 Apr 2014 11:02 AM PDT Researchers have found that an agent that inhibits mitochondrial division can overcome tumor cell resistance to a commonly used cancer drug, and that the combination of the two induces rapid and synergistic cell death. Separately, neither had an effect.  |
| Genetic testing beneficial in melanoma treatment Posted: 04 Apr 2014 11:02 AM PDT Genetic screening of cancer can help doctors customize treatments so that patients with melanoma have the best chance of beating it, according to the results of a clinical trial.  |
| Recurrent head and neck tumors have gene mutations that could be vulnerable to cancer drug Posted: 04 Apr 2014 11:02 AM PDT An examination of the genetic landscape of head and neck cancers indicates that while metastatic and primary tumor cells share similar mutations, recurrent disease is associated with gene alterations that could be exquisitely sensitive to an existing cancer drug.  |
