Researchers invent new imaging system to help detect malignant tissue during surgery

With the goal of making it easier for surgeons to detect malignant tissue during surgery and hopefully reduce the rate of cancer recurrence, scientists have invented a new imaging system that causes tumors to "light up" when a hand-held laser is directed at them.

Subsets of cells drive spread of multiple myeloma

Although it is among the most highly metastatic of all cancers, multiple myeloma is driven to spread by only a subset of the myeloma cells within a patient's body, researchers at Dana-Farber Cancer Institute have found in a study presented at the annual meeting of the American Society of Hematology.

Engineered cells reveal changes associated with learning, memory and reward

Scientists have created cells with fluorescent dyes that change color in response to specific neurochemicals. By implanting these cells into living mammalian brains, they have shown how neurochemical signaling changes as a food reward drives learning, they report in Nature Methods online October 26.

New method could help doctors better understand how drug abuse affects the brain

A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment options for recovering drug addicts.

Research finding offers potential therapeutic avenues for glioblastoma

Invading glioblastoma cells may hijack cerebral blood vessels during early stages of disease progression and damage the brain's protective barrier, a study in mice indicates. This finding could ultimately lead to new ways to bring about the death of the tumor, as therapies may be able to reach these deadly cells at an earlier time point than was previously thought possible.

New technique identifies tumors in real time in operating room

Before they excise a tumor, surgeons need to determine exactly where the cancerous cells lie. Now, research published today in The Optical Society's (OSA) journal Optics Letters details a new technique that could give surgeons cheaper and more lightweight tools, such as goggles or hand-held devices, to identify tumors in real time in the operating room.

Researchers develop fluorescent sensor to identify presence of drug used to spike beverages

A team of researchers from the National University of Singapore (NUS) has developed the world's first fluorescent sensor to identify the presence of a drug known as GHB that is commonly used to spike beverages. When the sensor is mixed with a sample of a beverage containing GHB, the mixture changes colour in less than 30 seconds, making detection of the drug fast and easy.
