Cell fusion triggers multiple genetic changes that convert normal cells to cancer cells

Although there is no one established universal cause of cancer, genetic changes are central to its development. The accumulation of spontaneous genetic changes, or mutations, that occur when cells divide can be hastened by exposure to carcinogens such as cigarette smoke (lung cancer) and infectious agents such as the papillomavirus (cervical cancer).

UC Davis' John S. Werner wins 2015 Verriest Medal from International Colour Vision Society

John S. Werner, a UC Davis neuroscientist and international authority on visual perception, has been selected to receive the 2015 Verriest Medal from the International Colour Vision Society for his contributions to understanding the structural and functional basis of color vision, how and why vision changes across the life span, and factors that contribute to loss of vision associated with disease. He will receive the award at the society's biennial symposium in Sendai, Japan, in July.

Philip Low to be recognized with AACR Award for Outstanding Achievement in Chemistry in Cancer Research

The American Association for Cancer Research will recognize Philip S. Low, PhD, with the ninth annual AACR Award for Outstanding Achievement in Chemistry in Cancer Research at the AACR Annual Meeting 2015, to be held in Philadelphia, April 18-22.

IU researchers awarded NIH grant to develop new weapon to fight against antibiotic-resistant bacteria

The alarming increase of antibiotic-resistant bacteria poses health and economic threats worldwide, with more than 2 million Americans infected by the bacteria each year. Now, a team of Indiana University chemists and biologists has been awarded a major grant to develop and use a chemical tagging method to better understand how bacteria build their cell wall, which is still the best target for new antibiotics.

Two new fluorescent dyes may help localize, resect brain tumors

Two new fluorescent dyes attracted to cancer cells may help neurosurgeons more accurately localize and completely resect brain tumors, suggests a study in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Study: Green tea compound may activate a cycle that kills oral cancer cells

A compound found in green tea may trigger a cycle that kills oral cancer cells while leaving healthy cells alone, according to Penn State food scientists. The research could lead to treatments for oral cancer, as well as other types of cancer.

Microscopic spheres of calcium phosphate linked to AMD development

Microscopic spheres of calcium phosphate have been linked to the development of age-related macular degeneration (AMD), a major cause of blindness, by UCL-led research.

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.

Rutgers scientists are developing new medical imaging method for early detection of cancer

A new medical imaging method being developed at Rutgers University could help physicians detect cancer and other diseases earlier than before, speeding treatment and reducing the need for invasive, time-consuming biopsies.

Molecular diagnostics and blood screening systems: an interview with Dr Bos and Dr Koppelman

Screening blood donations and molecular diagnostics for patients started in the nineties. At the beginning, the level of automation in molecular diagnostic testing was limited; most of the work had to be done manually.

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.

DNA-binding fluorescent dyes evaluate cytotoxicity in real-time during screening

High throughput screening of compounds in live cells is a powerful approach for discovering new drugs, but the potential for cell toxicity must be considered.

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.
