Study explores whether reducing smoke toxicant exposure affects biomarkers of biological effect

British American Tobacco has published the protocol for a clinical study designed to determine whether using reduced-toxicant prototype cigarettes that reduce smokers' exposure to smoke toxicants impacts biological effect (ISRCTN81286286).

Incidence of blood cancer is significantly higher in regions near facilities that release benzene

The incidence of a particular type of blood cancer is significantly higher in regions near facilities that release the chemical benzene into the environment. That is the conclusion of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. This and other studies like it will be critical to identifying and enacting public health policies to decrease or prevent cancer.

New method can pinpoint DNA mutations that could help treat cancer, tuberculosis

The slightest variation in a sequence of DNA can have profound effects. Modern genomics has shown that just one mutation can be the difference between successfully treating a disease and having it spread rampantly throughout the body.

IGTP, UAB discover first genetic biomarker to detect Lewy body dementia

The Germans Trias i Pujol Health Sciences Research Institute and the Universitat Autònoma de Barcelona have discovered the first genetic biomarker to detect Lewy body dementia, a disease that can be confused with Alzheimer's.

Implanting false memory in the brain can be possible, say MIT neuroscientists

The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

Researchers create calcium-sensitive proteins that respond quickly to changes in neuron activity

Princeton University researchers have created "souped up" versions of the calcium-sensitive proteins that for the past decade or so have given scientists an unparalleled view and understanding of brain-cell communication.

Rapamycin extends mice lifespan but has limited effects on aging

The body's repair mechanisms begin to fail with increasing age. As a result, signs of wear and tear appear and the risk for many diseases, including Alzheimer's disease, diabetes, cardiovascular disorders and cancer, increases.

Nanofiber scaffolds regulate apoptosis, proliferation in neural stem cells by altering gene expression

The surface characteristics of nanoscaffolds made by nanotechnology are more similar to the three-dimensional topological structure of the extracellular matrix and the effects on the biological behaviors of cells and tissue repair are more beneficial.

New way of looking at DNA

Stem cell genes seek each other in the cell nucleus. So a study by the Hubrecht Institute in Utrecht, the Netherlands, has found, published this week in Nature. “It’s a new way of looking at DNA.”

Adaptimmune initiates Phase I/IIa open-label clinical trial in patients with ovarian cancer

Adaptimmune announced today that it has opened a Phase I/IIa, multiple-site, two-cohort, open-label clinical trial in ovarian cancer at Roswell Park Cancer Institute (RPCI) in Buffalo, N.Y., and City of Hope (COH) in Duarte, Calif.

Scientists show link between lunar cycles and human sleep behavior

Many people complain about poor sleep around full moon. Scientists at the University of Basel in Switzerland now report evidence that lunar cycles and human sleep behavior are in fact connected.

Non-invasive optical techniques use LED, laser to view beneath skin

Impressive examples of new non-invasive optical techniques using lasers, light-emitting diodes (LEDs), and spectroscopic methods to probe and render images from beneath the surface of the skin are featured in a newly completed special section in the Journal of Biomedical Optics published by SPIE, the international society for optics and photonics.

Inner ear supporting cells protect hair cells by secreting HSP70

An underlying cause of hearing loss is the death of sensory hair cells in the inner ear, which can be damaged in response to a variety of factors including the use of aminoglycoside antibiotics.

New technology enables all of the world's crops to take nitrogen from the air

A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Study provides information on neural pathways involved in human word learning

Language is a uniquely human ability. The average vocabulary of a person consists of about thirty thousand words, although people show individual differences in their ability to learn a new language.

New species of adenovirus can spread from monkey to human, say researchers

Adenoviruses commonly infect humans, causing colds, flu-like symptoms and sometimes even death, but now UC San Francisco researchers have discovered that a new species of adenovirus can spread from primate to primate, and potentially from monkey to human.

Finding could aid in delivering personalized cancer medicine based on individual's genetics

Scientists at the Princess Margaret Cancer Centre have discovered a function of the tumor suppressor gene PTEN that helps explain why certain promising therapies fail in many cancer patients, a finding that could aid in delivering tailored, personalized cancer medicine based on an individual's genetics.

EGFR mutation testing dropped once funding from pharmaceutical industry discontinued

Significant advances have taken place in the management of patients with advanced and metastatic non-small-cell lung cancer over the last 5 years. Traditionally, all advanced NSCLC patients were treated in a similar manner.

Researchers find how brain cells communicate with each other in different voice tones

Brain cells talk to each other in a variety of tones. Sometimes they speak loudly but other times struggle to be heard. For many years scientists have asked why and how brain cells change tones so frequently. Today National Institutes of Health researchers showed that brief bursts of chemical energy coming from rapidly moving power plants, called mitochondria, may tune brain cell communication.

Supporting cells in the inner ear can help repair damaged sensory hair cells, say researchers

Researchers have found in mice that supporting cells in the inner ear, once thought to serve only a structural role, can actively help repair damaged sensory hair cells, the functional cells that turn vibrations into the electrical signals that the brain recognizes as sound.
