Study of cancer radiation therapy shows that DNA building blocks are susceptible to fragmentation

A new study relevant for cancer radiation therapy shows that DNA building blocks are susceptible to fragmentation. Scientists now have a better understanding of how short DNA strands decompose in microseconds

Scientists examine part of sample consisting of non-human DNA

Much of what we know about Oetzi - for example what he looked like or that he suffered from lactose intolerance - stems from a tiny bone sample which allowed the decoding of his genetic make-up.

Study finds that friends who are not biologically related still resemble each other genetically

If you consider your friends family, you may be on to something. A study from the University of California, San Diego, and Yale University finds that friends who are not biologically related still resemble each other genetically.

Drug paraphernalia triggers reward areas of brain differently in marijuana users

New research from The University of Texas at Dallas demonstrates that drug paraphernalia triggers the reward areas of the brain differently in dependent and non-dependent marijuana users.

Findings reveal mechanism underlying hippocampal neuronal injury after TBI

Traumatic brain injury (TBI) causes gene expression changes in different brain regions. Cyclooxygenase-2, glutamate receptor-2, and platelet activating factor receptor expression levels are related to the occurrence and development of TBI.

Biochemists find groups of tiny protein loops that help bacteria to establish infection

When it comes to infecting humans and animals, bacteria need a helping hand. Kansas State University biochemists have found the helping hand: groups of tiny protein loops on the surface of cells.

Research shows promise to speed up drug discovery for deadly diseases

Antibiotic resistance is depleting our arsenal against deadly diseases and infections, such as tuberculosis and Staph infections, but recent research shows promise to speed up the drug discovery process.

Researchers reveal molecular interplay between Roquin and RNA

The Roquin protein, discovered in 2005, controls T-cell activation and differentiation by regulating the expression of certain mRNAs. In doing so, it helps to guarantee immunological tolerance and prevents immune responses against the body's own structures that can lead to autoimmune disease.

Research sheds new light on brain's complicated barrier tissue

Research from the University of Copenhagen is shedding new light on the brain's complicated barrier tissue. The blood-brain barrier is an effective barrier which protects the brain, but which at the same time makes it difficult to treat diseases such as Alzheimer's.

Citalopram can increase efficacy of BMSCs differentiating into neuronal-like cells

There is evidence that selective serotonin reuptake inhibitor antidepressants can promote neuronal cell proliferation and enhance neuroplasticity both in vitro and in vivo.

Fatty acid transport proteins genetically linked to schizophrenia and ASD

Using diverse methodologies, neuroscientists from the RIKEN Brain Science Institute report that defects in Fatty Acid Binding Proteins (FABPs) may help to explain the pathology in some cases of schizophrenia and autism spectrum disorders.

Engineering single-celled parasite in cat's intestine as cancer vaccine

Toxoplasma gondii (T. gondii) is a single-celled parasite that is happiest in a cat's intestines, but it can live in any warm blooded animal. Found worldwide, T. gondii affects about one-third of the world's population, 60 million of which are Americans.

Study: Stress can disrupt process of fat tissue development

Using experimental models, researchers at Boston University School of Medicine (BUSM) showed that adenosine, a metabolite released when the body is under stress or during an inflammatory response, stops the process of adipogenesis, when adipose (fat) stem cells differentiate into adult fat cells.

Study reveals way to alleviate memory deficits for Alzheimer's disease patients

A new study from the Gladstone Institutes has revealed a way to alleviate the learning and memory deficits caused by apoE4, the most important genetic risk factor for Alzheimer's disease, improving cognition to normal levels in aged mice.

Personalized medicine for breast cancer patients may be just around the corner

For breast cancer patients, the era of personalized medicine may be just around the corner, thanks to recent advances by USC Stem Cell researcher Min Yu and scientists at Massachusetts General Hospital and Harvard Medical School.

New femtosecond infrared light source helps to directly visualize hydrogen-bonded molecules

Using a newly developed, ultrafast femtosecond infrared light source, chemists at the University of Chicago have been able to directly visualize the coordinated vibrations between hydrogen-bonded molecules -- the first time this sort of chemical interaction, which is found in nature everywhere at the molecular level, has been directly visualized.

Smoking may increase suicide risk

Cigarette smokers are more likely to commit suicide than people who don't smoke, studies have shown. This reality has been attributed to the fact that people with psychiatric disorders, who have higher suicide rates, also tend to smoke.

New tools for detecting and monitoring TB in captive elephants

Mycobacterium tuberculosis, the organism that causes tuberculosis in humans, also afflicts Asian (and occasionally other) elephants. Diagnosing and treating elephants with TB is a challenge, however, as little is known about how their immune systems respond to the infection.

Scientists launch project on northern Front Range of Colorado to track harmful pollutant

Scientists at the National Center for Atmospheric Research (NCAR) and partner organizations from across the country are launching a major field project on the northern Front Range of Colorado this month to track the origins of summertime ozone, an invisible but harmful pollutant.
