Cardiomyocytes can now be made cheaply and abundantly in the laboratory

Cardiomyocytes, the workhorse cells that make up the beating heart, can now be made cheaply and abundantly in the laboratory.

Bioengineers develop first structure to grow small human blood vessels

Mice and monkeys don't develop diseases in the same way that humans do. Nevertheless, after medical researchers have studied human cells in a Petri dish, they have little choice but to move on to study mice and primates. University of Washington bioengineers have developed the first structure to grow small human blood vessels, creating a 3-D test bed that offers a better way to study disease, test drugs and perhaps someday grow human tissues for transplant.

Heart-wall muscle fibers are locally arranged in a special ‘minimal surface’

A study led by researchers from McGill University provides new insights into the structure of muscle tissue in the heart - a finding that promises to contribute to the study of heart diseases and to the engineering of artificial heart tissue.

Common sparrow and Tyrannosaurus Rex are more closely related than believed

At first glance, it's hard to see how a common house sparrow and a Tyrannosaurus Rex might have anything in common. After all, one is a bird that weighs less than an ounce, and the other is a dinosaur that was the size of a school bus and tipped the scales at more than eight tons.

Giant cells protect fungus Cryptococcus neoformans during infection

Giant cells called "titan cells" protect the fungus Cryptococcus neoformans during infection, according to two University of Minnesota researchers. Kirsten Nielsen, Ph.D., an assistant professor in the department of microbiology, and recent Ph.D. recipient Laura Okagaki believe their discovery could help develop new ways to fight infections caused by Cryptococcus.

Scientists develop super-sensitive test that could detect diseases earlier

Scientists have developed an ultra-sensitive test that should enable them to detect signs of a disease in its earliest stages, in research published today in the journal Nature Materials.

Major new research facility opens at Imperial College London

A major new research facility at Imperial College London designed to expand and accelerate the translation of scientific discoveries into new ways of preventing, diagnosing and treating diseases was officially opened by George Osborne MP, Chancellor of the Exchequer, today.

New medicine can start and hasten healing of diabetic and other chronic sores

A unique new medicine that can start and hasten healing of diabetic and other chronic sores is being developed at Umeå University in Sweden. After several years of successful experimental research, it is now ready for clinical testing.

Researchers develop tentative model for diagnosis of colon cancer

Researchers from the Universidad Politécnica de Madrid's Facultad de Informática, the Universidad del País Vasco, the Gaiker Technology Centre (Biscay) and the Hospital de Cruces in Barakaldo, have developed a tentative model for the diagnosis of colon cancer based on a biomarker panel.

CDKN1C gene mutation contributes to IMAGe syndrome

A gene previously linked to too much growth in patients has now also been linked to growth restriction. Different forms of the gene can lead to very different conditions, according to research published today in the journal Nature Genetics.

New insight into immune-cell movement patterns

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team at the University of Pennsylvania has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators such as monkeys, sharks and blue-fin tuna use to hunt their prey.

UC Davis mathematicians help biologists to understand platelet formation

UC Davis mathematicians have helped biologists figure out why platelets, the cells that form blood clots, are the size and shape that they are. Because platelets are important both for healing wounds and in strokes and other conditions, a better understanding of how they form and behave could have wide implications.

Researchers develop new technique that converts stem cells into brain cells

A new technique that converts stem cells into brain cells has been developed by researchers at Lund University. The method is simpler, quicker and safer than previous research has shown and opens the doors to a shorter route to clinical cell transplants.

UCLA geneticists identify mutation responsible for IMAGe syndrome

UCLA geneticists have identified the mutation responsible for IMAGe syndrome, a rare disorder that stunts infants' growth. The twist? The mutation occurs on the same gene that causes Beckwith-Wiedemann syndrome, which makes cells grow too fast, leading to very large children.

Blocking Skp2 protein might inhibit glycolysis and treat breast cancer

HER2 and its epidermal growth factor receptor cousins mobilize a specialized protein to activate a major player in cancer development and sugar metabolism, scientists report in the May 25 issue of Cell.

UC Irvine immunologist to create new line of neural stem cells for MS

A UC Irvine immunologist will receive $4.8 million to create a new line of neural stem cells that can be used to treat multiple sclerosis.

UCSD scientists receive new CIRM grants to conduct stem cell-based research

Five scientists from the University of California, San Diego and its School of Medicine have been awarded almost $12 million in new grants from the California Institute for Regenerative Medicine (CIRM) to conduct stem cell-based research into regenerating spinal cord injuries, repairing gene mutations that cause amyotrophic lateral sclerosis and finding new drugs to treat heart failure and Alzheimer's disease.

Scientists show how hemizygous deletion can contribute to cancer

Chromosomal deletions in DNA often involve just one of two gene copies inherited from either parent. But scientists haven't known how a deletion in one gene from one parent, called a "hemizygous" deletion, can contribute to cancer.

City of Hope receives CIRM grant to develop T cell-based immunotherapy against glioma

City of Hope was granted a $5,217,004 early translational research award by the California Institute for Regenerative Medicine (CIRM) to support the development of a T cell-based immunotherapy that re-directs a patient's own immune response against glioma stem cells.

X-chromosome involved in development of bowel cancer

Scientists have shown for the first time that one of the sex chromosomes is involved in the development of a cancer that can afflict both genders, according to a Cancer Research UK-funded study in Nature Genetics.
