New strategy for outsmarting cancer through its own social intelligence

In the face of mounting evidence that cancer cells communicate, cooperate and even engage in collective decision-making, biophysicists and cancer researchers at Rice University, Tel Aviv University and Johns Hopkins University are suggesting a new strategy for outsmarting cancer through its own social intelligence.

Cyclin D3 protein regulates size and quantity of RBCs

The adult human circulatory system contains between 20 and 30 trillion red blood cells (RBCs), the precise size and number of which can vary from person to person. Some people may have fewer, but larger RBCs, while others may have a larger number of smaller RBCs. Although these differences in size and number may seem inconsequential, they raise an important question: Just what controls these characteristics of RBCs?

New method helps engineer tissues with embedded nanoscale networks

A multi-institutional research team has developed a method for embedding networks of biocompatible nanoscale wires within engineered tissues. These networks—which mark the first time that electronics and tissue have been truly merged in 3D—allow direct tissue sensing and potentially stimulation, a potential boon for development of engineered tissues that incorporate capabilities for monitoring and stimulation, and of devices for screening new drugs.

New device can measure mass of individual molecules one at a time

A team led by scientists at the California Institute of Technology (Caltech) have made the first-ever mechanical device that can measure the mass of individual molecules one at a time.

Scientists demonstrate automated worm sorter for biological research

Research into the genetic factors behind certain disease mechanisms, illness progression and response to new drugs is frequently carried out using tiny multi-cellular animals such as nematodes, fruit flies or zebra fish.

UD professor part of NIH-funded project to create artificial salivary glands

University of Delaware professor Xinqiao Jia is part of a research team breaking new ground in the creation of artificial salivary glands.

Fluorescent molecules 'tag' DNA and monitor looping process

In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material in some types of cells.

Researchers make major advance in efforts to regenerate damaged hearts

Researchers have made a major advance in efforts to regenerate damaged hearts. Grafts of human cardiac muscle cells, grown from embryonic stem cells, coupled electrically and contracted synchronously with host muscle following transplantation in guinea pig hearts.

Australia's top medical researchers for 2012 announced

Finalists for one of Australia’s longest running and most prestigious awards for medical research were announced today. This year’s winner will join a list of alumni winners that includes many of the country’s most respected scientists.

Ephrin-A5 blocks formation of new connections between neurons after stroke

Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain's recovery. In a mouse model, the researchers showed that blocking this molecule-called ephrin-A5--induces axonal sprouting, that is, the growth of new connections between the brain's neurons, or cells, and as a result promotes functional recovery.

HemoGlobe device can identify women with anemia

Could a low-cost screening device connected to a cell phone save thousands of women and children from anemia-related deaths and disabilities? That's the goal of Johns Hopkins biomedical engineering undergraduates who've developed a noninvasive way to identify women with this dangerous blood disorder in developing nations. The device, HemoGlobe, is designed to convert the existing cell phones of health workers into a "prick-free" system for detecting and reporting anemia at the community level.

Researchers turn inanimate silicone and living cardiac muscle cells into a jellyfish

Using recent advances in marine biomechanics, materials science, and tissue engineering, a team of researchers at Harvard University and the California Institute of Technology (Caltech) have turned inanimate silicone and living cardiac muscle cells into a freely swimming "jellyfish."

Activating NOTCH and AKT gene may trigger cholangiocarcinoma

A rare type of cancer thought to derive from cells in the bile ducts of the liver may actually develop when one type of liver cell morphs into a totally different type, a process scientists used to consider all but impossible. UCSF researchers triggered this kind of cellular transformation-and caused tumors to form in mice-by activating just two genes.

New eye-tracking device for amputees

Millions of people suffering from Multiple Sclerosis, Parkinson's, muscular dystrophy, spinal cord injuries or amputees could soon interact with their computers and surroundings using just their eyes, thanks to a new device that costs less than £40.

Sandia researchers develop SpinDx medical diagnostic tool

Researchers at Sandia National Laboratories have developed a lab-on-a-disk platform that they believe will be faster, less expensive and more versatile than similar medical diagnostic tools.

Researchers develop new silk-based stabilizer for vaccines and antibiotics

Researchers funded by the National Institutes of Health have developed a new silk-based stabilizer that, in the laboratory, kept some vaccines and antibiotics stable up to temperatures of 140 degrees Fahrenheit.

New optical microscope identifies rare breast cancer cells

The ability to distinguish and isolate rare cells from among a large population of assorted cells has become increasingly important for the early detection of disease and for monitoring disease treatments.

Bioengineers develop microfluidic platform to mechanically confine cancer cells

It's well known in conventional biology that during the process of mammalian cell division, or mitosis, a mother cell divides equally into two daughter cells. But when it comes to cancer, say UCLA researchers, mother cells may be far more prolific.

Novel biomimetic strategy can dissolve blood clots before they cause serious damage or even death

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have developed a novel biomimetic strategy that delivers life-saving nanotherapeutics directly to obstructed blood vessels, dissolving blood clots before they cause serious damage or even death.
