Coral reef winners and losers in a warmer world
In the world's first large-scale investigation of how climate affects the composition of coral reefs, an international team of marine scientists concludes that the picture is far more complicated than previously thought -- but that total reef losses due to climate change are unlikely.

New method may help detect marker for Alzheimer's disease earlier
Use of a new drug to detect the beta-amyloid plaques in the brain that are hallmark signs of Alzheimer's disease may help doctors diagnose the disease earlier, according to research that will be presented as part of the Emerging Science program (formerly known as Late-Breaking Science) at the American Academy of Neurology's 64th Annual Meeting in New Orleans April 21-28, 2012.

Effective local medical response to New Zealand earthquake helped reduce deaths and burden of injury
Just over a year after an earthquake struck Christchurch, New Zealand, on Feb.

Scientists identify FLT3 gene as a valid therapeutic target in acute myeloid leukemia
Through a groundbreaking new gene sequencing technology, researchers have demonstrated that the gene FLT3 is a valid therapeutic target in acute myeloid leukemia, AML, one of the most common types of leukemia.

Hebrew SeniorLife researchers discover genes linked to osteoporosis, bone breaks
Researchers at the Institute for Aging Research at Hebrew SeniorLife, an affiliate of Harvard Medical School, have co-authored the largest meta-analysis of genome-wide association studies of osteoporosis as part of an international consortium and have identified dozens of genetic variants found to be linked to an increased risk of developing osteoporosis and of suffering broken bones.

Stanford-spawned nanoparticles home in on brain tumors, boost accuracy of surgical removal
Like special-forces troops laser-tagging targets for a bomber pilot, tiny particles that can be imaged three different ways at once have enabled Stanford University School of Medicine scientists to remove brain tumors from mice with unprecedented accuracy.

Blood type A may predispose to some rotavirus infections
Some strains of rotavirus find their way into the cells of the gastrointestinal tract by recognizing antigens associated with the type A blood group, a finding that represents a new paradigm in understanding how this gut pathogen infects humans, said Baylor College of Medicine researchers in an online report in the journal Nature.

New software opens the door to wider use of 3-D imaging in the study of disease
Researchers have developed a novel, easy-to-use system for three-dimensional reconstruction and examination of tissues at microscopic resolution, with the potential to significantly enhance the study of normal and disease processes, particularly those involving structural changes.

Salk scientists discover how plants grow to escape shade
Mild mannered though they seem, plants are extremely competitive, especially when it comes to getting their fair share of sunlight.

New genetic regions linked to bone-weakening disease and fractures, Stanford researcher says
Thirty-two previously unidentified genetic regions associated with osteoporosis and fracture have been identified by a large, worldwide consortium of researchers, including Stanford Prevention Research Center chief John Ioannidis, M.D., D.Sc.

Despite obstacles, fine needle aspiration might be best diagnostic tool
Screening for lung cancer with low dose CT scans has been shown to save lives.

International team uncovers new genes that shape brain size, intelligence
In the world's largest brain study to date, a team of more than 200 scientists from 100 institutions worldwide collaborated to map the human genes that boost or sabotage the brain's resistance to a variety of mental illnesses and Alzheimer's disease.

New X-ray technique reveals structure of printable electronics
An innovative X-ray technique has given North Carolina State University researchers and their collaborators new insight into how organic polymers can be used in printable electronics such as transistors and solar cells.

BUSM researchers identify genes that influence hippocampal volume
An international team of researchers led by Boston University School of Medicine has identified four loci that appear to be associated with decreasing the volume of the hippocampus.

An Achilles heel of AML
The key to treating one of the most common types of human leukemia may lie within mutations in a gene called FLT3, according to new research led by physician-scientists at the University of California, San Francisco Helen Diller Family Comprehensive Cancer Center.

BASPCAN - UK-wide increase in number of children
Researchers at Queen's University Belfast have identified a 60 percent increase since 2006 in England in the numbers of children being recognized as in need of protection and on the child protection register.

Latest research confirms genetic susceptibility to lung cancer
Previous research has shown that Asian patients with lung cancer are more likely to harbor epidermal growth factor receptor mutations.

Urgent research needed to determine most effective follow-up care for lung cancer patients
Scientists say there is an urgent need for research into all aspects of follow-up care in lung cancer.

3-D RNA modeling opens scientific doors
In a paper published today in the journal Nature Methods, a team from the University of North Carolina at Chapel Hill demonstrates a simple, cost-effective technique for three-dimensional RNA structure prediction that will help scientists understand the structures, and ultimately the functions, of the RNA molecules that dictate almost every aspect of human cell behavior.

Large international study finds memory in adults impacted by versions of 4 genes
Two research studies, co-led by UC Davis neurologist Charles DeCarli and conducted by an international team that included more than 80 scientists at 71 institutions in eight countries, has advanced understanding of the genetic components of Alzheimer's disease and of brain development.
