Lensless cell phone microscope

Cell phones are accumulating a Swiss Army Knife-esqe assortment of capabilities; substituting as cameras, providing internet access, and soon operating as medical labs if Aydogan Ozcan's plans come to fruition. This month's cover article of the journal Lab on a Chip features the latest creation by the Ozcan group, a functioning prototype of a cell phone microscope.

Studying cells in 3-D could help develop drugs to prevent cancer from spreading: Researchers

Showing movies in 3-D has produced a box-office bonanza in recent months. Could viewing cell behavior in three dimensions lead to important advances in cancer research? A new study led by Johns Hopkins University engineers indicates it may happen. Looking at cells in 3-D, the team members concluded, yields more accurate information that could help develop drugs to prevent cancer's spread.

Tentative deal raises cigarette taxes in NY; Many Iowa hospitals close inpatient psychiatric units

Harvard Medical School, which has suffered financially due in part to a sharp decline in Harvard University's legendary endowment, has successfully negotiated a deal in which Boston's major teaching hospitals will contribute $36 million to the school over three years. The hospital money is a small portion of the medical school's $580 million annual budget, but it may represent a larger turning point in the unusual relationship between the country's top medical school and its prestigious hospital partners.

Electron cryomicroscopy helps observe molecules in hydrated state close to natural state

Gene expression takes place in two stages: the transcription of DNA to RNA by an enzyme called RNA polymerase, , followed by the translation of this RNA into proteins, whose behaviour affects the characteristics of each individual.

Canadian scientists describe safe, inexpensive way for kids to make microfluidic devices

With "hands-on" experiences in childhood and adolescence having sparked so many science careers, scientists in Canada are describing a quick, simple, safe, and inexpensive way for kids to participate in making microfluidic devices. Those devices are at the heart of lab-on-a chip, inkjet printing, DNA chip, and other technologies.

In vivo structure of senile plaques in brains of people with Alzheimer's disease

A team of scientists from Britain and the United States believe they may have identified the true in vivo structure of the senile plaques that are characteristically found in the brains of people with Alzheimer's disease.

Sialidase improves nerve regrowth, motor recovery and nervous system function: Researchers

Once damaged, nerves in the spinal cord normally cannot grow back and the only drug approved for treating these injuries does not enable nerve regrowth. Publishing online this week in the Early Edition of the Proceedings of the National Academy of Sciences, researchers at the Johns Hopkins University School of Medicine show that treating injured rat spinal cords with an enzyme, sialidase, improves nerve regrowth, motor recovery and nervous system function.

Dartmouth-Hitchcock Medical Center to implement BioImagene's digital pathology solutions

BioImagene, the leading provider of innovative digital pathology solutions, today announced that they have signed an agreement to equip Dartmouth-Hitchcock Medical Center (DHMC) with their complete suite of digital pathology solutions. DHMC will use iScan Coreo Au™ slide scanner and Virtuoso™ digital pathology application software to streamline laboratory workflow and enhance the Pathology Department's educational and residency programs.

Microscopic image sensor to speed up detection of tumors

To diagnose cancer reliably, doctors usually conduct a biopsy including tissue ana-lysis - which is a time-consuming process. A microscopic image sensor, fitted in an endoscope, is being developed for in vivo cancer diagnosis, to speed up the detection of tumors.

Researchers develop biosensors to monitor concentration of c-di-GMP within single living bacteria cells

Some species of bacteria perform an amazing reproductive feat. When the single-celled organism splits in two, the daughter cell - the swarmer - inherits a propeller to swim freely. The mother cell builds a stalk to cling to surfaces.

Scientists discover key mechanism of cancer cells

Many tumor cells would not be viable due to aberrant chromosome distribution if they had not developed a special trick. Scientists from the German Cancer Research Center have investigated which genes are responsible for this survival strategy of cancer cells.
