Artificial organelles transform free radicals into water and oxygen

Researchers at the University of Basel have successfully developed artificial organelles that are able to support the reduction of toxic oxygen compounds. This opens up new ways in the development of novel drugs that can influence pathological states directly inside the cell. The results have been published in the Journal Nano Letters.

Prostate cancers are fewer, smaller on walnut-enriched diet

SAN ANTONIO (July 16, 2013) — New research from the School of Medicine at The University of Texas Health Science Center San Antonio indicates that eating a modest amount of walnuts can protect against prostate cancer.

Damaging non-native forest pests at home in northeastern US

MORGANTOWN, W.Va., July 16, 2013 – Beginning with early colonists who landed in the New World loaded with dreams, grit and perhaps the continent's first alien forest pests, and continuing today with the expansion of global trade, the northeastern United States has been ground zero for damaging non-native forest pest invasions.

CAMH scientists discover genetic changes that may contribute to the onset of schizophrenia

Toronto -- Scientists from the Centre for Addiction and Mental Health (CAMH) have discovered rare genetic changes that may be responsible for the onset of schizophrenia. Several of these same genetic lesions had previously been found to have causal links to autism spectrum disorder (ASD). This discovery gives new support to the notion that multiple rare genetic changes may contribute to schizophrenia and other brain disorders.

Chest radiation cancer patients with risk factors should have CV screening every 5-10 years

Sophia Antipolis, 16 July 2013: Cancer patients who receive chest radiation should be screened for heart disease every 5-10 years, according to the European Association of Cardiovascular Imaging (EACVI) of the European Society of Cardiology (ESC) and the American Society of Echocardiography (ASE).

Their recommendations are outlined in the first expert consensus statement on screening for radiation-induced heart disease (RIHD), published today in European Heart Journal – Cardiovascular Imaging.1

New mode of cellular communication discovered in the brain

Researchers at Johannes Gutenberg University Mainz (JGU) have discovered a new form of communication between different cell types in the brain. Nerve cells interact with neighboring glial cells, which results in a transfer of protein and genetic information. Nerve cells are thus protected against stressful growth conditions. The study undertaken by the Mainz-based cell biologists shows how reciprocal communication between the different cell types contributes to neuronal integrity. Their results have been recently published in the journal PLOS Biology.

Protecting the body in good times and bad

The nasty side effects of radiation and chemotherapy are well known: fatigue, hair loss and nausea, to name a few. Cancer treatment can seem as harsh as the disease because it can't differentiate healthy cells from cancerous cells, killing both.

But what if there were a way to control or stop the growth of cancer cells without harming other cells?

Novel study using new technologies outlines importance of California condor social groups

The intricate social hierarchy of the California condor, an endangered species, is something that could not be studied until recently due to the severe reduction of this population in the wild. The first formal study on this species, based on remote video observation of reintroduced populations, indicates that the species has a complex system of interactions based on dominance.

Genetic secrets of the world's toughest little bird

Scientists from Griffith University have taken part in an international study which has revealed the genetic secrets of how a small bird can survive in one of the most hostile environments on earth.

The ground tit (Parus humilis), lives in the Tibetan plateau, the largest high-altitude land mass in the world. This study has found molecular signatures in the ground tit genome which reveal how it copes with the extreme living conditions of this habitat.

Even healthy-looking smokers have early cell damage which destroys necessary genetic programming

NEW YORK (July 16, 2013) -- Smokers who've received a clean bill of health from their doctor may believe cigarettes haven't harmed their lungs. However, researchers at Weill Cornell Medical College have found that even smokers who seem healthy have damaged airway cells, with characteristics similar to cells found in aggressive lung cancer.

New Web-enabled technology records the presence of species by analyzing their sounds

Identifying, and monitoring the fluctuations of thousands of species in tropical ecosystems is a difficult challenge, but newly developed technology now makes it much easier. Scientists report on new cyberinfrastructure which enables real-time acoustic recording and subsequent species identification in remote locations around the world. Thousands of audio recordings of tropical birds, frogs, monkeys, and insects in Puerto Rico and Costa Rica have been captured (using automated recording stations placed in their natural habitat) and analyzed to identify the species concerned.

The Line Islands Collection -- Microbial dynamics of coral reef robustness and decline

Coral reefs face serious threats primarily arising from climate change, unsustainable fishing, and pollution. To better understand the underlying processes, a multidisciplinary series of studies is being conducted by researchers, investigating variability in coral reef community structure and microbial dynamics across gradients of natural and anthropogenic stress. Their results are published in the new PeerJ "Line Islands Collection – Microbial dynamics of coral reef robustness and decline" (named after their upcoming expedition to the Line Islands).

Fat in organs and blood may increase risk of osteoporosis

OAK BROOK, Ill. -- Excess fat around the belly has recently been identified as a risk factor for bone loss. Now, a new study has determined that excess liver and muscle fat also may be detrimental to bone.

The study, published online in the journal Radiology, found that obese people with higher levels of fat in their liver, muscle tissue and blood also have higher amounts of fat in their bone marrow, putting them at risk for osteoporosis.

H7N9 influenza strain resistant to antivirals, but tests fail to identify resistance

Some strains of the avian H7N9 influenza that emerged in China this year have developed resistance to the only antiviral drugs available to treat the infection, but testing for antiviral resistance can give misleading results, helping hasten the spread of resistant strains.

RNA-interference pesticides will need special safety testing

Standard toxicity testing is inadequate to assess the safety of a new technology with potential for creating pesticides and genetically modifying crops, according to a Forum article published in the August issue of BioScience. The authors of the article, Jonathan G. Lundgren and Jian J.
