New molecular sensor could identify zinc-related diseases

Scientists have developed a new molecular sensor that can reveal the amount of zinc in cells, which could tell us more about a number of diseases, including type 2 diabetes. The research, published today in Nature Methods, opens the door to the hidden world of zinc biology by giving scientists an accurate way of measuring the concentration of zinc and its location in cells for the first time.

New Fraxel re:store Dual system with Thulium laser launched by Solta Medical

Solta Medical, Inc. (Nasdaq: SLTM) today announced the launch of its new Fraxel re:store(R) Dual system, providing superior results for large body areas during a single treatment. Prior to the non-ablative Fraxel re:store Dual system, laser skin resurfacing procedures were largely limited to the face.

New tool for scientists - light used to manipulate cell movement

One of the biggest challenges in scientists' quest to develop new and better treatments for cancer is gaining a better understanding of how and why cancer spreads. Recent breakthroughs have uncovered how different cellular proteins are turned 'on' or 'off' at the molecular level, but much remains to be understood about how protein signaling influences cell behavior.

Scientists combine two nanoparticles into one tiny package

Nanoparticles are being developed to perform a wide range of medical uses - imaging tumors, carrying drugs, delivering pulses of heat. Rather than settling for just one of these, researchers at the University of Washington have combined two nanoparticles in one tiny package.

Harnessing nanoparticles to track cancer cell changes

The more dots there are, the more accurate a picture you get when you connect them. Cancer researchers adopting that philosophy have developed a new imaging technology that could give scientists the ability to simultaneously measure as many as 100 or more distinct features in or on a single cell. In a disease such as cancer, that capability would provide a much better picture of what is going on in individual tumor cells.

New diagnostic technique detects possible Alzheimer's biomarker in blood

A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH).

Novel light-sensitive compounds show promise for photodynamic cancer therapy

Chemists at the University of California, Santa Cruz, have developed novel compounds that show promise for photodynamic cancer therapy, which uses light-activated drugs to kill tumor cells.

Experimental imaging technique reveals ‘tell tale’ brain plaques in Alzheimer's

Researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have demonstrated a new, highly detailed x-ray imaging technique that could be developed into a method for early diagnosis of Alzheimer's disease.

Rapid test for prostate cancer

Researchers have developed the test by using light energy to measure the level of citrate in fluid samples from the prostate gland. The technique could provide the basis of a rapid means of detecting prostate cancer in the future. Almost a quarter of male cancers in the UK are diagnosed as prostate cancer and more than 10,000 men die from the disease each year.

New generation of nanotools for ultra-sensitive measurements at the atomic level

As researchers push towards detection of single molecules, single electron spins and the smallest amounts of mass and movement, Yale researchers have demonstrated silicon-based nanocantilevers, smaller than the wavelength of light, that operate on photonic principles eliminating the need for electric transducers and expensive laser setups.

A magic bullet for superbugs

Attaching an antimicrobial drug, which is activated by light, to a peptide that binds to bacteria and stops them making toxins, produced a "magic bullet" that was highly effective at killing the superbug, methicillin-resistant Staphylococcus aureus (MRSA).

New radiation-free targeted therapy detects and eliminates breast cancer tumors in mice

Combining a compound known as a gallium corrole with a protein carrier results in a targeted cancer therapy that is able to detect and eliminate tumors in mice with seemingly fewer side effects than other breast-cancer treatments, says a team of researchers from the California Institute of Technology (Caltech), the Israel Institute of Technology (Technion) and the Cedars-Sinai Medical Center.

DNA-based assembly line for precision nano-cluster construction

Building on the idea of using DNA to link up nanoparticles - particles measuring mere billionths of a meter - scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have designed a molecular assembly line for predictable, high-precision nano-construction.

Lifeless cells ensure sharp vision

Seemingly dead cells perform a surprising task in the lens of a fish eye. Every morning and evening they change the lens's capacity to refract light in order to enhance color perception during the day and night vision when it's dark. This is shown in new research from Lund University in Sweden.
