Researchers reveal types of genes necessary for brain development

Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS Genetics.

A noisy brain is a healthy brain

Canadian scientists have shown that a noisy brain is a healthy brain. "Brain noise" is a term that has been used by neuroscientists to describe random brain activity that is not important to mental function.

Report says cancer clinicians should understand and consider the economic impact of new interventions

Cancer clinicians should understand and consider the economic impact of new interventions, which often have substantial costs, according to a report appearing in the July/August issue of CA: A Cancer Journal for Clinicians, a peer-reviewed journal of the American Cancer Society.

Quantum dot nanoparticles can penetrate skin through minor abrasions

Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion, providing insight into potential workplace concerns for healthcare workers or individuals involved in the manufacturing of quantum dots or doing research on potential biomedical applications of the tiny nanoparticles.

Healing touch therapy

Often, a gentle hand on your shoulder when you're upset is all it takes to ease your mind and calm your nerves. Now, University of Cincinnati (UC) researchers are looking at a similar occurrence by pairing a complementary therapy known as Healing Touch with mild sedation to see if the technique truly calms patients undergoing minor procedures.

Electrostatic-based RNA assays technique could revolutionize medical diagnostics

The dream of personalized medicine - in which diagnostics, risk predictions and treatment decisions are based on a patient's genetic profile - may be on the verge of being expanded beyond the wealthiest of nations with state-of-the-art clinics.

New comprehensive map of brain connections

An international team of researchers has created the first complete high-resolution map of how millions of neural fibers in the human cerebral cortex -- the outer layer of the brain responsible for higher level thinking -- connect and communicate. Their groundbreaking work identified a single network core, or hub, that may be key to the workings of both hemispheres of the brain.

Dividing cells find their middle by following a protein contour map

Self-organization keeps schools of fish, flocks of birds and colonies of termites in sync. It's also, according to new research, the way cells regulate the final stage of cell division. Scientists at Rockefeller University have shown that a protein-chemistry-based contour map, which helps individual proteins locate the center of their cell without direction from a 'master organizer,' is key to ensuring accurate division during mitosis.

Molecular movies reveal dynamic lives of proteins

Capturing moving images of tiny protein molecules is the aim of a new research project announced today at Imperial College London. The research will reveal, on extremely short timescales, the miniscule movements of proteins which help carry out important biological processes in people, animals, insects and plants.

Neuroscientists pinpoint how neural activity boosts blood flow to the brain

New research from Harvard University neuroscientists has pinpointed exactly how neural activity boosts blood flow to the brain. The finding has important implications for our understanding of common brain imaging techniques such as fMRI, which uses blood flow in the brain as a proxy for neural activity.

Pregnancy may protect against bladder cancer

Female mice that had never become pregnant had approximately 15 times as much cancer in their bladders as their counterparts that had become pregnant, according to new findings by investigators at the University of Rochester Medical Center. Their work appears online as a rapid communication in the journal Urology.

Quantum dots stop RNA interference in living cells

More than 15 years ago scientists discovered a way to stop a particular gene in its tracks. The Nobel Prize-winning finding holds tantalizing promise for medical science, but so far it has been difficult to apply the technique, known as RNA interference, in living cells.

Automated magnetic resonance imaging technique assists in earlier Alzheimer's diagnosis

An automated system for measuring brain tissue with magnetic resonance imaging (MRI) can help physicians more accurately diagnose Alzheimer's disease at an earlier stage according to a new study published in the July issue of the journal Radiology.

Individualized therapies for non-Hodgkin's lymphoma identified with PET

Positron emission tomography (PET) could be an important tool for identifying non-Hodgkin's lymphoma patients who are likely to respond well to treatment with 90 ibritumomab tiuxetan (IT)-the first radioimmunotherapy treatment approved for use by the U.S. Food and Drug Administration, said researchers at the Society of Nuclear Medicine's 55th Annual Meeting.

Molecular imaging helps follow the progression of Alzheimer's disease

In the past, physicians were able only to follow the progression of Alzheimer's disease (AD) through careful clinical histories, noting the often subtle changes associated with cognitive decline over a number of years.
