Johns Hopkins scientists expose cancer cells' universal 'dark matter'
Using the latest gene sequencing tools to examine so-called epigenetic influences on the DNA makeup of colon cancer, a Johns Hopkins team says its results suggest cancer treatment might eventually be more tolerable and successful if therapies could focus on helping cancer cells get back to normal in addition to strategies for killing them.

Hitting moving RNA drug targets
By accounting for the floppy, fickle nature of RNA, researchers at the University of Michigan and the University of California, Irvine, have developed a new way to search for drugs that target this important molecule.

Flooding of ancient Salton Sea linked to San Andreas earthquakes
Southern California's Salton Sea, once a large natural lake fed by the Colorado River, may play an important role in the earthquake cycle of the southern San Andreas Fault and may have triggered large earthquakes in the past.

ESC calls for renaming of term cardiac hypertrophy
A position paper, published online today in the European Journal of Heart Failure, suggests that use of the general term myocardial remodeling should be preferred.

Recommendations proposed for increasing arboreta membership, sustaining programs
Facing challenges such as maturing memberships and flat enrollment, arboreta and public gardens are exploring ways to sustain programming and activities.

Ocean currents speed melting of Antarctic ice
Stronger ocean currents beneath West Antarctica's Pine Island Glacier Ice Shelf are eroding the ice from below, speeding the melting of the glacier as a whole, according to a new study in Nature Geoscience.

Twin-head cucumber system reduces start-up costs
A technique for raising twin-head transplants and a twin-head ''V'' high-wire cucumber system was developed to address the issue of high start-up costs for greenhouse operations.

Genetic testing for inherited cardiac conditions is 'patchy' in Europe
An expert consensus statement on the value of diagnostic genetic testing for these inherited cardiac conditions will be unveiled today at the EHRA EUROPACE 2011 congress in Madrid.

Premature aging caused by some HIV drugs, study shows
A class of anti-retroviral drugs commonly used to treat HIV, particularly in Africa and low income countries, can cause premature ageing, according to research published today in the journal Nature Genetics.

Massachusetts General Hospital, Iacocca Foundation announce promising results of Phase I diabetes trial
Promising results of the Phase I clinical trial of the generic drug BCG (bacillus Calmette-Guerin) to treat advanced type I diabetes were announced today at the American Diabetes Association scientific sessions in San Diego, by a research team led by Denise Faustman, MD, PhD, director of the Mass.

Berkeley scientists pioneer nanoscale nuclear materials testing capability
A technique for testing irradiated materials on the nanoscale that yields results on the macroscale has been developed by scientists at Lawrence Berkeley National Laboratory, the University of California at Berkeley, and Los Alamos National Laboratory.

CU researchers develop new software to advance brain image research
A University of Colorado Boulder research team has developed a new software program allowing neuroscientists to produce single brain images pulled from hundreds of individual studies, trimming weeks and even months from what can be a tedious, time-consuming research process.

Engineering blue-hued flowers
Experiments were designed to identify the anthurium cultivars and colors with the best potential to transform to blue-colored flowers.

Genetic study shows that low body fat may not lower risk for heart disease and diabetes
Having a lower percentage of body fat may not always lower your risk for heart disease and diabetes, according to a study by an international consortium of investigators, including two scientists from the Institute for Aging Research.

U of T researchers crack full-spectrum solar challenge
U of T Engineering researchers report a new solar cell that may pave the way to inexpensive coatings that efficiently convert the sun's rays to electricity.

Prodigal plankton species makes first known migration from Pacific to Atlantic via Pole
European scientists say the melting Arctic has opened a Northwest Passage for Pacific species to enter the Atlantic, including a tiny plankton, unseen in the Atlantic for 800,000 years -- a return unwelcome due to its impact on the marine food web.

Emissions from energy use in the water sector are poorly understood
Greater understanding is needed of greenhouse gas emissions from energy use in the water sector if it is to meet sustainability goals, according to researchers at the University of East Anglia.

Rogue blood cells may contribute to post-surgery organ damage
A study from scientists at Queen Mary, University of London, sheds new light on why people who experience serious trauma or go through major surgery, can suffer organ damage in parts of the body which are seemingly unconnected to the injury.

SIV-resistant monkeys close the gates to viral infection
Sooty mangabeys, a type of African monkey, can survive infection by SIV, a relative of HIV, and not succumb to AIDS.

Scientists identify a novel mechanism for evolution of highly aggressive cancers
Singapore and US scientists have made the striking finding that Barrett's esophagus work, published online in the journal Cell on June 24, 2011, is essential to developing therapeutics for esophageal cancer.

New non-destructive method to estimate leaf area index in vegetables
Scientists designed a new, non-destructive method for estimated leaf area index (LAI) in vegetable crops.

Genome editing, a next step in genetic therapy, corrects hemophilia in animals
Using an innovative gene therapy technique called genome editing that hones in on the precise location of mutated DNA, scientists have treated the blood clotting disorder hemophilia in mice.
