Synthetic human tissue aids in testing photoacoustic and ultrasonic imaging technologies

The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

Luminescent upconversion nanocrystals can detect cancer cells

Upconversion emission materials are ideal for bioimaging due to its effectiveness as contrast agents for the detection of cancer cells, more so when the background emission of non-cancerous tissues can be minimised. These materials could be used as biomarkers for luminescent labeling of cancerous cells. Opaque tissues can be turned into glassy, transparent substances by using these biomarkers which rely on near-infrared excitation.

Less incidence of nearsightedness in kids who spend more time outdoors: Study

A new study finds that children who play outdoors often are smarter, leaner and stronger than kids more inclined toward indoor activities. They're less likely to suffer from nearsightedness, in which objects in the distance appear blurry.

HMS, EPFL to collaborate on 6 pioneering neuroengineering projects

Two of the world's leading universities are joining forces to combine neuroscience and engineering in order to alleviate human suffering caused by such neurological disabilities as paralysis and deafness. Scientists, engineers, and clinicians at Harvard Medical School (HMS) and Ecole Polytechnique F-d-rale de Lausanne (EPFL) will collaborate on six pioneering neuroengineering projects made possible thanks to a $3.6 million grant from the Bertarelli Foundation.

Narrow band imaging an equally effective alternative to chromoendoscopy for dysplasia

A new study from Spain finds that narrow band imaging appears to be a less time-consuming and equally effective alternative to chromoendoscopy for the detection of dysplasia (abnormal growths) in patients with long-standing inflammatory bowel disease.

Microscopy with helium ions may greatly enhance both surface and sub-cellular imaging

The ability to obtain an accurate three-dimensional image of an intact cell is critical for unraveling the mysteries of cellular structure and function. However, for many years, tiny structures buried deep inside cells have been practically invisible to scientists due to a lack of microscopic techniques that achieve adequate resolution at the cell surface and through the entire depth of the cell.

Anesthesia and liposuction

Liposuction is a body contouring procedure, not a cure for obesity. The results are judged with a mirror and not a scale. The procedure is ideally suited for men and women with localized fat deposits that are resistant to diet and exercise. Men typically want their "spare tire" and excess fat on their chest removed, while women want their abdomen, hips, and thighs reduced.

University of Groningen surgeons perform first fluorescence-guided ovarian cancer surgery

The first fluorescence-guided surgery on an ovarian cancer patient was performed using a cancer cell "homing device" and imaging agent created by a Purdue University researcher.

Exposure to 'white' LED light suppresses melatonin production

Exposure to the light of white LED bulbs, it turns out, suppresses melatonin 5 times more than exposure to the light of High Pressure Sodium bulbs that give off an orange-yellow light. "Just as there are regulations and standards for 'classic' pollutants, there should also be regulations and rules for the pollution stemming from artificial light at night," says Prof. Abraham Haim of the University of Haifa.

NJIT to honor electrical engineer for nanotechnology research

What do brilliantly colored glass, advanced batteries, and innovative technology for the regulation of brain functions have in common? They are nano-scale structures far smaller than the wavelengths of energy coursing through them in different regions of the electromagnetic spectrum, said NJIT Professor Haim Grebel.

Molecular Devices adds TUNE detection cartridge to SpectraMax Paradigm Detection Platform

Today, Molecular Devices, a leading provider of instruments, software, and consumables for drug discovery and life sciences research, announced the addition of the TUNE detection cartridge to the SpectraMax Paradigm Multi-Mode Microplate Detection Platform. The breakthrough technology of TUNE with wavelength flexibility in a monochromator device and up to 10x the sensitivity will benefit both the research and screening markets.

Discovery in rare disease may shed light on common causes of blindness

In a rare eye disease, the retina degenerates because light-receiving cells fail to regenerate, research led by a student at Case Western Reserve University School of Medicine shows.

Scientists discover nanoparticles can disrupt intracellular transport pathways

Scientists at the Centre of Cancer Biomedicine at the Norwegian Radium Hospital are the first to show that uptake and accumulation of nanoparticles in cells can disrupt important intracellular transport pathways.

Pulse oximetry can identify newborns with congenital heart disease

About 1 in every 120 babies are born with congenital heart disease (CHD), of which about 25 percent is critical, requiring special care early in life. CHD is responsible for more deaths in the first year of life than any other birth defect, but often outcomes can be improved with early detection.

Femtosecond-laser ablation of Xenopus melanocytes for studies of cell migration, wound repair

Using an ultrafast femtosecond laser, researchers at Tufts University in Medford, Mass., were able to label, draw patterns on, and remove individual melanocytes cells from a species of frog tadpole (Xenopus) without damaging surrounding cells and tissues.

Two-color stimulated emission depletion microscopy in living cells

Researchers are able to achieve extremely high-resolution microscopy through a process known as stimulated emission depletion (STED) microscopy. This cutting-edge imaging system has pushed the performance of microscopes significantly past the classical limit, enabling them to image features that are even smaller than the wavelength of light used to study them.

Flexible-fiber CO2 laser-assisted ablation safe for endoscopic assisted transsphenoidal craniotomies

A new study has shown the Flexible-Fiber CO2 laser to safely cut and coagulate during endoscopic assisted transsphenoidal craniotomies (TSC) without the line of sight problems encountered with conventional CO2 lasers.

Light-switching complex could help detect signs of Alzheimer's disease

A breakthrough in sensing at Rice University could make finding signs of Alzheimer's disease nearly as simple as switching on a light.
