Geographic information system software offers new way to study human remains

A common type of geographic mapping software offers a new way to study human remains. In a recent issue of the American Journal of Physical Anthropology, researchers describe how they used commercially available mapping software to identify features inside a human foot bone - a new way to study human skeletal variation.

PNAS: Ras proteins bring tension to the phosphate chain

Proteins accelerate certain chemical reactions in cells by several orders of magnitude. The molecular mechanism by which the Ras protein accelerates the cleavage of the molecule GTP and thus slows cell growth is described by biophysicists at the Ruhr-Universit-t Bochum led by Prof. Dr. Klaus Gerwert in the Online Early Edition of the journal PNAS.

New 3D endoscope at UMDNJ-The University Hospital can treat complex neurosurgical diseases

Ana Cores, a 54-year old Hackensack resident, worried about how a sudden loss of peripheral vision would impact the quality of her life. After undergoing MRIs, eye exams and many diagnostic tests, Cores opted to visit UMDNJ-The University Hospital where Dr. James K. Liu, a skull base neurosurgeon, and Dr. Jean Anderson Eloy, an otolaryngologist, used a new three- dimensional endoscope to remove a brain tumor through her nose that was pressing on her optic nerve and causing her to go blind.

EmbryoScope Time-lapse system identifies abnormal development events in embryos

Which embryos have the best opportunity to develop into a viable pregnancy? A new technology provides a surprising answer. A major challenge in the field of IVF is selecting the single best embryo which is likely to result in a live birth. Currently, embryologists must remove the embryo from a standard incubator to perform 2 or 3 short evaluations of the developing embryo under the microscope, at fixed time-points over 3-5 days, in order to assess embryo quality prior to transferring an embryo to the patient.

Popular Science magazine names University of Minnesota chemist among ‘Brilliant 10’

University of Minnesota chemist Christy Haynes has been named one of Popular Science magazine's "Brilliant 10," an honor that recognizes an elite group of young scientists whose research is expected to dramatically impact their fields. Haynes' profile was published today on the PopSci website and is featured in the Popular Science magazine now on newsstands.

Stanford and MBL scientists win prestigious Lasker Awards

Scientists who invented new ways to study how "cargo" is moved within cells and, as a result, discovered a new biological motor protein, kinesin, at the Marine Biological Laboratory (MBL) in Woods Hole, Mass., have received the prestigious 2012 Lasker Award for Basic Medical Research, the Albert and Mary Lasker Foundation announced today.

Flow cytometry renders PCR testing unnecessary for most AML patients

Early treatment response is a powerful predictor of long-term outcome for young patients with acute myeloid leukemia (AML). The information can help physicians decide whether a more intensive approach is needed. Research led by St. Jude Children's Research Hospital investigators has identified the best test for measuring that response and guiding therapy.

Clathrin protein plays a key role in cell division

A protein called "clathrin," which is found in every human cell and plays a critical role in transporting materials within them, also plays a key role in cell division, according to new research at the University of California, San Francisco.

Book on basic stereology for biologists and neuroscientists

Stereological techniques allow biologists to create quantitative, three-dimensional descriptions of biological structures from two-dimensional images of tissue viewed under the microscope. For example, they can accurately estimate the size of a particular subcellular compartment, the total length of a mass of blood vessels, or the number of neurons or synapses in a particular region of the brain.

S. African, S. Korean research team developing smartphone HIV testing device, application

Researchers from South Africa and South Korea are developing a smartphone-based device and application able to "photograph and analyze blood samples in areas far from laboratories to diagnose HIV and even measure the health of [patients'] immune systems," Agence France-Presse reports.

High-dose vitamin D appears to help patients with TB recover more quickly

For decades before antibiotics became generally available, sunshine was used to treat tuberculosis, with patients often being sent to Swiss clinics to soak up the sun's healing rays. Now, for the first time scientists have shown how and why heliotherapy might, indeed, have made a difference.

NYU-Poly creates ultra-sensitive biosensor to identify small single virus particles

Researchers at Polytechnic Institute of New York University (NYU-Poly) have created an ultra-sensitive biosensor capable of identifying the smallest single virus particles in solution, an advance that may revolutionize early disease detection in a point-of-care setting and shrink test result wait times from weeks to minutes.

Confocal light sheet microscopy yields high-resolution views of brain’s neural pathways

Shortly after the Hubble Space Telescope went into orbit in 1990 it was discovered that the craft had blurred vision. Fortunately, Space Shuttle astronauts were able to remedy the problem a few years later with supplemental optics. Now, a team of Italian researchers has performed a similar sight-correcting feat for a microscope imaging technique designed to explore a universe seemingly as vast as Hubble's but at the opposite end of the size spectrum—the neural pathways of the brain.

New method can differentiate between breast cancer patients with good and poor prognosis

It is now possible to identify aggressive breast cancers by interpreting the mathematical patterns in the cancer genome. Researchers at the University of Oslo, Norway (UiO) have developed a completely new method for differentiating between breast cancer patients with high and low risks of dying from the illness.

Six common myths about prostate cancer

When it comes to prostate cancer, there's a lot of confusion about how to prevent it, find it early and the best way - or even whether - to treat it. Below are six common prostate cancer myths along with research-based information from scientists at Fred Hutchinson Cancer Research Center to help men separate fact from fiction.
