Fuzzy logic predicts cell aging

Philadelphia, PA – The process of aging disturbs a broad range of cellular mechanisms in a complex fashion and is not well understood. Computer models using fuzzy logic might help to unravel these complexities and predict how aging progresses in cells and organisms, according to a study from Drexel University in Philadelphia and Children's Hospital Boston.

Oceanographers call for more ocean observing in Antarctica

Rutgers' Oscar Schofield and five colleagues from other institutions have published in Science, calling for expanded ocean-observing in the Antarctic, particularly in the Western Antarctic Peninsula, or WAP.

University of Minnesota researchers clear major hurdle in road to high-efficiency solar cells

University of Minnesota researchers clear major hurdle in road to high-efficiency solar cells

A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent.

Risk of heart attack in patients

Rome, Italy, Friday 18 June: Rheumatoid Arthritis (RA) patients face a two-fold increased risk of suffering a Myocardial Infarction (MI, heart attack) versus the general population, which is comparable to the increased risk of MI seen in diabetes patients, according to results of a new study presented today at EULAR 2010, the Annual Congress of the European League Against Rheumatism in Rome, Italy.

Women who consume large amounts of tea have increased risk of rheumatoid arthritis

Rome, Italy, Friday 18 June 2010: Women who drink tea have an increased risk of developing Rheumatoid Arthritis (RA) compared with those who drink none (p=0.04), according to results presented today at EULAR 2010, the Annual Congress of the European League Against Rheumatism in Rome, Italy. Further results from the same study showed no correlation between the amount of coffee consumption and RA incidence (p=0.16).

Partners grieve rheumatoid arthritis diagnosis as much as patients

Rome, Italy, Friday 17 June: Partners of patients newly diagnosed with rheumatoid arthritis (RA) are equally emotionally affected by the diagnosis and go through the same grieving process as the patients themselves, according to the results of a study presented today at EULAR 2010, the Annual Congress of the European League Against Rheumatism in Rome, Italy.

Quantum dot research could mean highly efficient solar cells

Quantum dot research could mean highly efficient solar cells

AUSTIN, Texas—Conventional solar cell efficiency could be increased from the current limit of 30 percent to more than 60 percent, suggests new research on semiconductor nanocrystals, or quantum dots, led by chemist Xiaoyang Zhu at The University of Texas at Austin.

Zhu and his colleagues report their results in this week's Science.

Change blindness - researchers predict it in humans using computer intelligence

Rockville, MD — Scientists have just come several steps closer to understanding change blindness — the well studied failure of humans to detect seemingly obvious changes to scenes around them — with new research that used a computer-based model to predict what types of changes people are more likely to notice.

These findings on change blindness were presented in a Journal of Vision article, "A semi-automated approach to balancing bottom-up salience for predicting change detection performance."

New analysis on problems between archaeology and pharaonic chronology, based on radiocarbon dating

BEER-SHEVA, ISRAEL June 17, 2010 -- In a just published article in Science magazine (June 18, 2020), Prof. Hendrik J. Bruins of Ben-Gurion University of the Negev presents novel implications related to new developments in the radiocarbon dating of Pharaonic Egypt.

Academic internists release principles for Medicare GME reform

Washington, DC (June 17, 2010)—The Alliance for Academic Internal Medicine (AAIM) has identified core principles that delineate the shortfalls of graduate medical education (GME) funding. In light of the current state of Medicare GME financing and the Medicare Payment Advisory Commission's (MedPAC's) June 2010 report, AAIM encourages GME reform to address these shortfalls in light of societal health care needs.

Battle of the bugs leaves humans as collateral damage

It's a tragedy of war that innocent bystanders often get caught in the crossfire. But now scientists at the University of Pennsylvania and the University of Oxford have shown how a battle for survival at a microscopic level could leave humans as the unlikely victims.

In work funded by the US Public Health Service and the Wellcome Trust, the researchers have found a possible explanation for why some bacteria turn nasty, even at great risk to their own survival.

Gulf oil spill: Mississippi River hydrology may help reduce oil onshore

 Mississippi River hydrology may help reduce oil onshore

The Gulf of Mexico: what role will the Mississippi River play in oil washing ashore and into delta wetlands?

One of the spill's greatest environmental threats is to Louisiana's wetlands, scientists believe.

But there may be good news ahead.

Storing carbon dioxide deep underground in rock form

KNOXVILLE -- As carbon dioxide continues to burgeon in the atmosphere causing the Earth's climate to warm, scientists are trying to find ways to remove the excess gas from the atmosphere and store it where it can cause no trouble.

Sigurdur Gislason of the University of Iceland has been studying the possibility of sequestration of carbon dioxide (CO2) in basalt and presented his findings today to several thousand geochemists from around the world at the Goldschmidt Conference hosted by the University of Tennessee, Knoxville, and Oak Ridge National Laboratory.
