Genetically altered spermless ‘mozzies’ to combat malaria

In a fresh new attempt to combat malaria, researchers have developed another way to reduce the numbers of the malaria-spreading blood-suckers: introduce genetically altered spermless males into the population.

New study supports DNA-based 'biomarker' blood test for prostate cancer screening

A new study supports the use of a DNA-based "biomarker" blood test as a complement to the prostate-specific antigen (PSA) test currently offered to screen men for prostate cancer. University of Cincinnati (UC) researchers report their findings online ahead of print in the British Journal of Cancer.

Researchers discover gene variant linked to meningiomas

The causes of brain tumours have been hard to discern in most cases. But Umeå researchers have previously identified an inherited predisposition for brain tumours, and now, in an international collaboration, they have also discovered a genetic variation that increases the risk of a certain type of brain tumour, called meningiomas.

Affymetrix announces commercialization of next-generation human transcriptome array

Affymetrix, Inc. today announced commercialization of the next-generation human transcriptome array demonstrated by Stanford University researchers to be superior to mRNA sequencing (RNA-Seq) in gene expression profiling studies.

Leica Microsystems, CMED partner to co-develop and market automated FISH kits

China Medical Technologies, Inc. (CMED), a leading China-based advanced in-vitro diagnostic ("IVD") company, and Leica Biosystems, a division of Leica Microsystems, a world leader in microscopes and scientific instruments, today announced that they have established a sales, research and development collaboration to co-develop and market automated FISH kits to be used on the Leica BOND system.

Anisotropic encoding of three-dimensional space by place and grid cells

Animal's brains are only roughly aware of how high-up they are in space, meaning that in terms of altitude the brain's 'map' of space is surprisingly flat, according to new research.

Researchers use SNAP technology to assess fetal gene expression in amniotic fluid

Researchers have demonstrated the feasibility of focused fetal gene expression analysis of target genes found in amniotic fluid using Standardized NanoArray PCR (SNAP) technology.

New insights into cancer-induced intussusceptive angiogenesis

Researchers have gained a new understanding of the way in which growing tumors are fed and how this growth can be slowed via angiogenesis inhibitors that eliminate the blood supply to tumors. This represents a step forward towards developing new anti-cancer drug therapies.

Study: miR-200s play a paradoxical role in metastatic cancer development

While they may be small in size, a family of tiny molecules called microRNAs could potentially play a large role in the process of cancer metastasis, or the spread of cancer from one area of the body to another.

De novo mutations account for 50% of sporadic cases of schizophrenia

Columbia University Medical Center researchers have shown that new, or "de novo," protein-altering mutations—genetic errors that are present in patients but not in their parents—play a role in more than 50 percent of "sporadic" —i.e., not hereditary—cases of schizophrenia.

New finding about cell metabolism may have implications for neurodegenerative disorders

Cells are the building blocks of the human body. They are a focus of scientific study, because when things go wrong at the cellular and molecular level the consequences for human health are often significant.

Women with RAD51D gene fault more likely to develop ovarian cancer

Cancer Research UK-funded scientists have discovered that women who carry a faulty copy of a gene called RAD51D have almost a one in 11 chance of developing ovarian cancer, the most significant ovarian cancer gene discovery for more than a decade, reveals a study in Nature Genetics1 today.

Early burn out of male Bustard may explain how biological aging evolved: Research

For male houbara bustards sexual extravagance is the key to attracting mates in some of the world's harshest desert environments. However, new research in Ecology Letters reveals that males who perform the most extravagant sexual displays will suffer from premature biological aging and will pass their reproductive prime years earlier than their less ostentatious rivals.

Biologists show that females themselves can limit evolution of increased elaboration

Female cognitive ability can limit how melodious or handsome males become over evolutionary time, biologists from The University of Texas at Austin, Louisiana State University Health Sciences Center and the Smithsonian Tropical Research Institute have observed.

Scientist urges federal officials to decide on genetically engineered salmon for consumption

A Purdue University scientist is urging federal officials to decide whether genetically engineered salmon would be allowed for U.S. consumption and arguing that not doing so may set back scientific efforts to increase food production.

Researchers discover lack of oxygen in the lungs after mold invasion

Researchers led by Montana State University have found a surprising condition that occurs in the lungs after an invasion of a common mold that can cause deadly infections in humans.

New analytical method can develop specific drugs against parasites, bacteria

A team led by Professor Malcolm McConville from the Bio21 Institute, University of Melbourne developed a new analytical method which can be used for many infectious parasites and bacteria.

Diet and genetics dictate adult jaw shape

Researchers at Johns Hopkins found that use over time and not just genetics informs the structure of jaw bones in human populations. The researchers say these findings may be used to predict the diet of an ancient population, even if little evidence exists in the fossil record. It can also make it easier for scientists to pinpoint the genetic relationship between fossils.

Metallofullerene platform holds promise for treatment of brain tumors

A single compound with dual function - the ability to deliver a diagnostic and therapeutic agent - may one day be used to enhance the diagnosis, imaging and treatment of brain tumors, according to findings from Virginia Commonwealth University and Virginia Tech.

Scientists identify small molecule inhibitors of cellular uptake

Scientists from Freie Universität Berlin and the NeuroCure Cluster of Excellence led by biochemist Volker Haucke in collaboration with colleagues from Australia and the Leibniz Institute for Molecular Pharmacology in Berlin have developed small molecules that inhibit the internalization of important signaling molecules but also of pathogenic organisms such as the immunodeficiency virus and bacteria into cells.
