| Dissecting the animal diet, past and present Posted: 18 Mar 2016 09:31 AM PDT It's time to settle a very old food fight. In a new study, experts argue that scientists need to focus as much on 'when' animals eat as they do 'what' animals eat. Without the proper time context, they say, an animal's diet can tell very different stories. |

| The legacy of mercury in Lake Superior Posted: 18 Mar 2016 08:15 AM PDT Old mercury may have new import. Researchers examined dozens of core samples and found more mercury from past mining is sticking around in local waterways than they thought. At its height, mercury deposition from mining was 1,000 times greater than the area's baseline. The findings could have implications for industrial sites around the Great Lakes. |
| Out for blood: Fluid dynamics explain how quickly a vampire could drain your blood Posted: 18 Mar 2016 08:15 AM PDT Throughout human history there have been tales of vampires -- bloodsucking creatures of folklore that prey on their victims by draining their life essence, usually via the blood. To coincide with the 85th anniversary of Tod Browning's 'Dracula' (1931), students have used fluid dynamics to examine how long it would take for the undead fiend to drain an average human's blood -- and have calculated that it would take only 6.4 minutes to drain 15 per cent of the blood from the external carotid artery in a human's neck. |
| Astronomers found a star with a record variation period Posted: 18 Mar 2016 08:14 AM PDT Astronomers who created a global network of robotelescopes MASTER detected that a bright star TYC 2505-672-1 has actually faded significantly. That finding led to new questions: so, the scientists assume that TYC 2505-672-1 is actually a double star system, though a nature of its companion remains unknown. |
| New gene identified as cause, early indicator of breast cancer Posted: 18 Mar 2016 08:14 AM PDT When mutated, a gene known for its ability to repair DNA, appears to instead cause breast cancer, scientists report. Mutations of the gene are known to be present in both early onset breast and ovarian cancer. Now scientists have shown that the stem, or progenitor cells, which should ultimately make healthy breast tissue, can also have GT198 mutations that prompt them to instead make a perfect bed for breast cancer. |

| Mercury rising? Potential mercury methylation in two California rivers Posted: 18 Mar 2016 07:21 AM PDT Gold mining in California in the 19th century was a boon for the state's economy but not so much for the environment. Mining left a protracted legacy that impacts the natural landscape even today. Mercury, used in the gold extraction process, has been detected throughout the Lower Yuba/Feather River system in the state's Central Valley, and its presence could prove dangerous to local wildlife. |

The discovery suggests possible avenues for treating the empathically challenged. |
| Natural resilience to major life stressors is not as common as thought Posted: 18 Mar 2016 07:20 AM PDT Natural resilience may not be as common as once thought, research shows, and that when confronted with a major life-altering event many people can struggle considerably and for longer periods of time. The research questions prior claims that resilience is the 'usual' response to major life stressors by looking at longitudinal data in a more nuanced way and making less generalization about the human response to such dramatic events. |

In some cases this pain can be so extreme that patients need to have their bladder removed (cystectomy). |
| 'Climate responsibility': New methodology applied to China Posted: 18 Mar 2016 06:04 AM PDT Using a new approach scientists have found that China's "climate responsibility", is not as significant as initially estimated. However, rather paradoxically, the latter country's "responsibility" may increase rapidly over the coming years, due to future policies designed to improve the country's air quality. Researchers obtained these results using a new methodology developed to determine the impacts of greenhouse gas emissions, aerosols and compounds which are chemically active in the atmosphere on a country's climate. |

Researchers identified specific factors (patient age at initial treatment, restoration size and restorative material) that significantly associated with restoration survival. |
| Rescue inhaler study: New approach increases mastery of life-saving technique Posted: 18 Mar 2016 05:56 AM PDT A rescue inhaler can be a lifesaver during an asthma or COPD flareup, but using a rescue inhaler is complicated and misuse is common, putting patients' lives at risk. An education strategy, called teach-to-goal, may help patients use their inhalers properly during these critical times, according to new research. |
| Forgetting to learn: Neural mechanisms in mouse brains indicate that we actively forget as we learn Posted: 18 Mar 2016 05:56 AM PDT They say that once you've learned to ride a bicycle, you never forget how to do it. But new research suggests that while learning, the brain is actively trying to forget. |
| Dentistry: Evidence-practice gap for sealant application Posted: 18 Mar 2016 05:56 AM PDT In this study, the researchers aimed to examine dentist practice patterns regarding treatment recommendation of dental sealants and identify characteristics associated with this recommendation.

| Dentistry: New biotechnology to inhibit microRNA activity and novel applications Posted: 18 Mar 2016 05:56 AM PDT A new plasmid-based microRNA inhibitor system (PMIS) effectively inhibits microRNA (miR) activity in cells and mice. In this study, researchers generated a novel RNA-based hairpin molecule carrying an anti-sense miR seed sequence that effectively knocks down endogenous miRs and mitigates their effects on messenger RNA in the cell. By using a native RNA-based molecule for miR knockdown, the PMIS platform avoids many of the traditional pitfalls associated with miR inhibition using synthetic oligonucleotides. |
| New report reveals hundreds still dying in detention Posted: 17 Mar 2016 08:35 PM PDT An ongoing culture of secrecy, poor access to specialist mental health services and a lack of high quality independent investigations has contributed to hundreds of non-natural deaths in detention, according to a new report. |
