Jerusalem, Nov. 6, 2012 -- Identifying fingerprints on paper is a commonly used method in police forensic work, but unfortunately it is not easy to make those fingerprints visible. Now, scientists at the Hebrew University of Jerusalem have developed a new approach for making such fingerprints more readily readable.

Methane is formed under the absence of oxygen by natural biological and physical processes, e.g. in the sea floor. It is a much more powerful greenhouse gas than carbon dioxide. Thanks to the activity of microorganisms this gas is inactivated before it reaches the atmosphere and unfolds its harmful effects on Earth's climate. Researchers from Bremen have now proven that these microorganisms are quite picky about their diet.

Adults 18-24 years old with high blood pressure were 28 percent less likely to be diagnosed during doctor visits than those 60 and older, according to findings presented at the American Heart Association's Scientific Sessions 2012.

"These young patients come to the clinic and their blood pressure is recorded," said Heather Johnson, M.D., lead researcher of the study. "They have high blood pressure, but there's no documentation of a diagnosis. We wanted to find out why."

No matter what climate you live in, you're more likely to die of heart-related issues in the winter, according to research presented at the American Heart Association's Scientific Sessions 2012.

"This was surprising because climate was thought to be the primary determinant of seasonal variation in death rates," said Bryan Schwartz, M.D., lead author of the study.

Combining cancer medication with a drug for erectile dysfunction and one for heart transplants helped kill cancer cells and protected the heart from damage, in a study presented at the American Heart Association's Scientific Sessions 2012.

For decades, doxorubicin has been a powerful anti-cancer treatment for various human cancers, including breast, ovarian, colon and prostate. But its use has been limited due to harmful, possibly irreversible effects on the heart.

(Philadelphia, PA) – When a person has a heart attack, portions of the heart muscle die in the next several days or even weeks if deprived of oxygen for long enough. The recovering heart slowly remodels itself, even fostering the growth of new blood vessels, in an attempt to regain some of its former function. But all too often, the remodeling is actually harmful, and the damaged heart is on an inevitable downward slide to heart failure.

DUBLIN, November 6, 2012 – Taiho Pharmaceutical Co., Ltd. (HQ: Tokyo, President: Masayuki Kobayashi), the developer of the first orally available fluorouracil (FU) Chemotherapeutic treatment (TS-1/S-1), is presenting early stage data for eight novel oncology compounds, including potential first-in-class therapies.

Boston, Mass.—Using a combination of surgical procedures developed over the last 11 years, surgeons at Boston Children's Hospital have established a new approach for rebuilding the heart in children born with a severe heart defect called hypoplastic left heart syndrome (HLHS). This "staged left ventricle recruitment" (SLVR) strategy uses the existing standard single-ventricle treatment for HLHS and additional procedures to spur the body's capacity for healing and growth and encourage the small left ventricle in these children to grow and function.

(Philadelphia, PA) – Scientists for the first time have evidence showing how a widely used type of "targeted" cancer drug can be dangerous to the heart.

With its deeply embedded roots, sturdy trunk and dense profusion of branches, the Tree of Life is a structure of nearly unfathomable complexity and beauty. While major strides have been made to establish the evolutionary hierarchy encompassing every living species, the project is still in its infancy.

A multi-institutional team of researchers has sequenced the DNA of 6,700 exomes, the portion of the genome that contains protein-coding genes, as part of the National Heart, Lung and Blood Institute (NHLBI)-funded Exome Sequencing Project, one of the largest medical sequencing studies ever undertaken.

Biologists at the University of Rochester have determined how blind mole rats fight off cancer—and the mechanism differs from what they discovered three years ago in another long-lived and cancer-resistant mole rat species, the naked mole rat.

CHICAGO – A study of smokers admitted to a large urban teaching hospital in Massachusetts found that 18.4 percent reported smoking during their hospitalization, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Results of a new study show that episodes of reduced precipitation in the Southern Rocky Mountains, especially during the 2001-2002 drought, greatly accelerated a rise in numbers of mountain pine beetles. The overabundance is a threat to regional forests.

The research is the first to chart the evolution of the current pine beetle epidemic in the southern Rocky Mountains.

It compared patterns of beetle outbreaks in the two primary host species, the ponderosa pine and lodgepole pine, said University of Colorado at Boulder (CU-Boulder) researcher Teresa Chapman.

New research shows that ocean turbulence directly affects the ability of microscopic marine organisms to recycle organic material back into the food web.

Results of the study are published in this week's issue of the journal Science.

Scientists John Taylor of Cambridge University and Roman Stocker at MIT found that there's a relationship between the natural movement of water in the ocean and the ability of marine bacteria to act as recyclers.
