Ocean carbon uptake more variable than thought

2014-11-13
(Press-News.org) The Earth's oceans are thought to have taken up about one quarter of the carbon dioxide (CO2) that humans pumped into the atmosphere in the past 2 decades. While this drives acidification and has consequences for sea life, it also moderates the rate of climate change.

Researchers recently set out to create a global model of CO2 uptake using fine-scale observations on a global scale. Between 1998 and 2011, they found strong interannual variations, with the Pacific Ocean dominating the global flux variability.

"Shipboard surface water CO2 measurements are the backbone of data-based ocean CO2 sink estimates. Thanks to an increasing community effort, we are now able to estimate how much the ocean CO2 sink varies on inter-annual to decadal timescales," said Dr. Peter Landschützer, lead author of the Global Biogeochemical Cycles study.

Ocean primed for more El Niño: ANU media release

Ocean primed for more El Niño: ANU media release
2014-11-13
The ocean is warming steadily and setting up the conditions for stronger El Niño weather events, a new study has shown. A team of US, Australian, and Canadian researchers sampled corals from a remote island in Kiribati to build a 60-year record of ocean surface temperature and salinity. "The trend is unmistakeable, the ocean's primed for more El Niño events," says lead-author Dr Jessica Carilli, now based at the University of Massachusetts, Boston. Team member Dr Helen McGregor from the Research School of Earth Sciences at The Australian National University ...

Study: Disgust leads people to lie and cheat; cleanliness promotes ethical behavior

2014-11-13
HOUSTON - (Nov. 13, 2014) - While feelings of disgust can increase behaviors like lying and cheating, cleanliness can help people return to ethical behavior, according to a recent study by marketing experts at Rice University, Pennsylvania State University and Arizona State University. The study highlights the powerful impact emotions have on individual decision-making. "As an emotion, disgust is designed as a protection," said Vikas Mittal, the J. Hugh Liedtke Professor of Marketing at Rice's Jones Graduate School of Business. "When people feel disgusted, they tend to ...

New findings could help keep satellites and space debris from colliding

2014-11-13
Half a million objects, including debris, satellites, and the International Space Station, orbit the planet in the thermosphere, the largest layer of Earth's atmosphere. To predict the orbits--and potential collisions--of all this stuff, scientists must forecast the weather in the thermosphere. Researchers who analyzed the role that gravitational effects of the Moon have on the thermosphere found that satellites taking different paths around the planet--circling over the poles, around the equator, or any route in between--will experience different levels of lunar-induced ...

UNC researchers silence leading cancer-causing gene

UNC researchers silence leading cancer-causing gene
2014-11-13
CHAPEL HILL, NC - Researchers from the UNC School of Medicine and colleagues at The University of Texas MD Anderson Cancer Center have developed a new approach to block the KRAS oncogene, one of the most frequently mutated genes in human cancer. The approach, led by Chad Pecot, MD, an assistant professor of medicine at UNC, offers another route to attack KRAS, which has proven to be an elusive and frustrating target for drug developers. The new method relies upon a specifically sequenced type of small interfering RNA - or siRNA. The findings, published in the journal ...

UCI team develops test to rapidly diagnose bloodstream infection

2014-11-13
Irvine, Calif., Nov. 13, 2014 -- A new bloodstream infection test created by UC Irvine researchers can speed up diagnosis times with unprecedented accuracy, allowing physicians to treat patients with potentially deadly ailments more promptly and effectively. The UCI team, led by Weian Zhao, assistant professor of pharmaceutical sciences, developed a new technology called Integrated Comprehensive Droplet Digital Detection. In as little as 90 minutes, IC 3D can detect bacteria in milliliters of blood with single-cell sensitivity; no cell culture is needed. The work appears ...

Clues to one of Earth's oldest craters revealed

2014-11-13
The Sudbury Basin located in Ontario, Canada is one of the largest known impact craters on Earth, as well as one of the oldest due to its formation more than 1.8 billion years ago. Researchers who took samples from the site and subjected them to a detailed geochemical analysis say that a comet may have hit the area to create the crater. "Our analysis revealed a chondritic platinum group element signature within the crater's fallback deposits; however, the distribution of these elements within the impact structure and other constraints suggest that the impactor was a comet. ...

What leads to weight loss success in adults with asthma?

2014-11-13
Among overweight and obese adults who had asthma and participated in weight loss programs, more severe asthma, male sex, and improvements in eating behaviors were all linked with better success at losing weight. The finding that individuals with more severe asthma may have a greater motivation to lose weight suggests that these individuals should be targeted for intervention. Also, gender tailoring of weight loss programs may be useful to enhance weight loss success, said Lisa Wood, senior author of the Respirology study. INFORMATION: ...

People show 'blind insight' into decision making performance

2014-11-13
People can gauge the accuracy of their decisions, even if their decision making performance itself is no better than chance, according to a new study published in Psychological Science, a journal of the Association for Psychological Science. In the study, people who showed chance-level decision making still reported greater confidence about decisions that turned out to be accurate and less confidence about decisions that turned out to be inaccurate. The findings suggest that the participants must have had some unconscious insight into their decision making, even though ...

Many dialysis patients unprepared for emergencies and disasters

2014-11-13
Philadelphia, PA (November 13, 2014) -- Patients on dialysis are very vulnerable during emergencies or disasters, but many are unprepared for such situations, according to two studies that will be presented at ASN Kidney Week 2014 November 11¬-16 at the Pennsylvania Convention Center in Philadelphia, PA. Dialysis patients are highly dependent on technologies to sustain their lives, with ongoing needs for transportation, electricity, and water for the dialysis apparatus. Interruption of these needs by a natural disaster can be devastating. Naoka Murakami, MD, PhD ...

Canadians with cystic fibrosis living 20 years longer than they did 2 decades ago

Canadians with cystic fibrosis living 20 years longer than they did 2 decades ago
2014-11-13
TORONTO, Nov. 13, 2014--Canadians with cystic fibrosis are living almost 20 years longer than they did two decades ago, according to a research paper published today. The median survival age was 49.7 years in 2012, up from 31.9 years in 1990, Dr. Anne Stephenson, a respirologist and research at St. Michael's Hospital wrote in the European Respiratory Journal. Since the paper was written, Dr. Stephenson has updated the median survival age to include Cystic Fibrosis Canada data from 2013 and reported the median age of survival has in fact reached 50.9 years. In addition, ...
