Research on 3D scaffolds sets new bar in lung regeneration Posted: 07 Mar 2014 01:59 PM PST For the estimated 12.7 million people with chronic obstructive pulmonary disorder, the third leading cause of death in the US, innovative research efforts in the field of tissue regeneration hold promise. In end-stage lung disease, transplantation is sometimes the only viable therapeutic option, but organ availability is limited and rejection presents an additional challenge. New research focuses on lung tissue bioengineering, which involves the use of a scaffold -- or framework -- of lungs from human cadavers to engineer new lungs for patients with end-stage disease. The studies have examined multiple perspectives on the process of stripping the cellular material from these lungs and replacing it with stem cells in an effort to grow new, healthy lungs for transplantation.

New class of antibiotics discovered by chemists Posted: 07 Mar 2014 01:59 PM PST A new class of antibiotics to fight bacteria such as methicillin-resistant Staphylococcus aureus and other drug-resistant bacteria that threaten public health has been discovered by a team of chemists. The new class, called oxadiazoles, was discovered in silico (by computer) screening and has shown promise in the treatment of MRSA in mouse models of infection. MRSA has become a global public-health problem since the 1960s because of its resistance to antibiotics. In the United States alone, 278,000 people are hospitalized and 19,000 die each year from infections caused by MRSA. Only three drugs currently are effective treatments, and resistance to each of those drugs already exists.

NASA's WISE survey finds thousands of new stars, but no 'Planet X' Posted: 07 Mar 2014 01:06 PM PST After searching hundreds of millions of objects across our sky, NASA's Wide-Field Infrared Survey Explorer (WISE) has turned up no evidence of the hypothesized celestial body in our solar system commonly dubbed "Planet X."

Promising news for producing fuels through artificial photosynthesis Posted: 07 Mar 2014 10:36 AM PST There's promising news from the front on efforts to produce fuels through artificial photosynthesis. A new study shows that nearly 90 percent of the electrons generated by a hybrid material designed to store solar energy in hydrogen are being stored in the target hydrogen molecules.

New theory on cause of endometriosis Posted: 07 Mar 2014 10:36 AM PST Changes to two previously unstudied genes are the centerpiece of a new theory regarding the cause and development of endometriosis, a chronic and painful disease affecting one in 10 women. The discovery suggests epigenetic modification, a process that enhances or disrupts how DNA is read, is an integral component of the disease and its progression.

That sinking feeling: NASA radar demonstrates ability to foresee sinkholes Posted: 07 Mar 2014 10:12 AM PST New analyses of NASA airborne radar data collected in 2012 reveal the radar detected indications of a huge sinkhole before it collapsed and forced evacuations near Bayou Corne, La., that year. The findings suggest such radar data, if collected routinely from airborne systems or satellites, could at least in some cases foresee sinkholes before they happen, decreasing danger to people and property.

Mystery of planet-forming disks explained by magnetism Posted: 07 Mar 2014 09:46 AM PST Astronomers say that magnetic storms in the gas orbiting young stars may explain a mystery that has persisted since before 2006. Researchers using NASA's Spitzer Space Telescope to study developing stars have had a hard time figuring out why the stars give off more infrared light than expected. The planet-forming disks that circle the young stars are heated by starlight and glow with infrared light, but Spitzer detected additional infrared light coming from an unknown source.

Cells appearing normal may actually be harbingers of lung cancer Posted: 07 Mar 2014 08:11 AM PST Airways near lung tumors provide clues to the genetics of cancer that suggest that seemingly healthy cells may in fact hide clues that lung cancer will later develop, according to a study. Examination of gene expression in patients with non-small cell lung cancer (NSCLC) showed these areas can be rich with cancer markers. In addition, researchers discovered the previously unknown role of a cancer-promoting gene in the airways of smokers with lung cancer.

Hospital food safety measures reduce risk of contaminated hospital food Posted: 07 Mar 2014 08:11 AM PST A new study found more than 80 percent of raw chicken used in hospitals in food for patients and staff was contaminated with a form of antibiotic resistant bacteria called extended-spectrum beta-lactamase producing E. coli. While sufficient preparation eliminated the presence of bacteria, poultry meat delivered to hospital kitchens remains a potential point of entry for these dangerous bacteria into the hospital.

Pre-term birth leads to increased risk of asthma, wheezing disorders Posted: 07 Mar 2014 08:10 AM PST Researchers have published findings strongly suggesting that preterm birth -- prior to 37 weeks gestation -- increases the risk of asthma and wheezing disorders during childhood, and that the risk of developing these conditions increases as the degree of prematurity increases. The findings are based on a systematic review and meta-analysis of 30 studies that investigated the association between preterm birth and asthma/wheezing disorders among 1.5 million children.

Smartphones become 'eye-phones' with low-cost devices Posted: 07 Mar 2014 08:10 AM PST Researchers have developed two inexpensive adapters that enable a smartphone to capture high-quality images of the front and back of the eye. The adapters make it easy for anyone with minimal training to take a picture of the eye and share it securely with other health practitioners or store it in the patient's electronic record.

Magnetically stimulated flow patterns offer strategy for heat transfer problems Posted: 07 Mar 2014 08:10 AM PST Researchers have discovered how to harness magnetic fields to create vigorous, organized fluid flows in particle suspensions.

Genome of sesame sheds new light on oil biosynthesis Posted: 07 Mar 2014 07:02 AM PST Researchers have successfully cracked the genome of high oil content crop sesame, providing new lights on the important stages of seed development and oil accumulation, and potential key genes for sesamin production.

Inherited Alzheimer's damage greater decades before symptoms appear Posted: 07 Mar 2014 07:02 AM PST The progression of Alzheimer's may slow once symptoms appear and do significant damage, according to a study investigating an inherited form of the disease. Through an international study, researchers have found rapid neuronal damage begins 10 to 20 years before symptoms appear. The next part of the study involves a clinical trial using a range of imaging techniques, and analysis of blood and cerebrospinal fluid, as participants trial new drugs to test their safety, side effects and changes within the brain.

Infants using known verbs to learn new nouns: Before infants begin to talk in sentences, they are paying careful attention to conversations Posted: 07 Mar 2014 07:02 AM PST New research demonstrates that even before infants begin to talk in sentences, they are paying careful attention to the way a new word is used in conversations, and they learn new words from this information in sentences.

Epigenetic changes could explain type 2 diabetes Posted: 07 Mar 2014 07:02 AM PST People with type 2 diabetes have epigenetic changes on their DNA that healthy individuals do not have. This has been shown in a major study by researchers who also found epigenetic changes in a large number of genes that contribute to reduced insulin production. "This shows that the risk of developing type 2 diabetes is not only genetic, but also epigenetic," said the leading author.

Nasal filter looks promising for allergy sufferers Posted: 07 Mar 2014 07:02 AM PST A newly developed type of filter can help people with nasal symptoms from seasonal hay fever, clinical research suggests. The filter, which is not yet in production, works by being inserted in both nostrils. Depending on the filter's density, it blocks specific particles in the air -- including pollen from grass, which is one of the most frequent causes of hay fever (seasonal allergic rhinitis).

Lifesaving sensor for full bladders under development Posted: 07 Mar 2014 07:01 AM PST Many people suffer from a neurological disease that means that they have difficulties with urinating and incontinence, and have problems controlling their bladders. Spinal injuries can damage the nerve supply to the bladder, meaning that people cannot tell when their bladder is full and needs to be emptied. This then creates an excessively high pressure on the bladder, which affects the kidneys and can lead to damage that may be life-threatening. Current methods for resolving this issue includes a measure of pressure in the bladder with a catheter, which can be uncomfortable. Now, researchers are developing tiny sensors to be implanted in patients for measuring pressure in the bladder.

UV light accelerates cancer cells that creep along outside of blood vessels Posted: 07 Mar 2014 07:00 AM PST Deadly skin cancer (melanoma) cells spread by creeping along the outside of blood vessels: extravascular metastatic migration (EVMM). Ultraviolet light exposure accelerates EVMM in a mouse model, new research has found. Now researchers are targeting new drugs that slow or stop EVMM, potentially reducing the death rate from melanoma.

Teen elephant mothers die younger but have bigger families Posted: 07 Mar 2014 05:40 AM PST Asian elephants that give birth as teenagers die younger than older mothers but raise bigger families during their lifetime, according to new research.

Europe's largest badger study finds rare long-distance movements Posted: 07 Mar 2014 05:40 AM PST European badgers can make journeys of more than 20km -- distances longer than previously thought –- researchers have found. The study could help design more effective interventions to reduce the spread of bovine tuberculosis between badger populations, something that is essential if transmission to cattle is to be controlled.

Urbanization exposes French cities to greater seismic risk Posted: 07 Mar 2014 05:40 AM PST French researchers have looked into data mining to develop a method for extracting information on the vulnerability of cities in regions of moderate risk, creating a proxy for assessing the probable resilience of buildings and infrastructure despite incomplete seismic inventories of buildings. The research exposes significant vulnerability in regions that have experienced an 'explosion of urbanization.'

Activity more than location affects perception of earthquakes Posted: 07 Mar 2014 05:40 AM PST A new study by Italian researchers suggests that a person's activity at the time of the quake influences their perception of shaking more than their location. Whether a person is at rest or walking plays a greater role in their perception of ground motion than whether they were asleep on the first or sixth floor of a building. People in motion had the worst perception.

Software analyzes apps for malicious behavior Posted: 07 Mar 2014 05:40 AM PST Apps on web-enabled mobile devices can be used to spy on their users. Computer scientists have developed software that shows whether an app has accessed private data. To accomplish this, the program examines the "bytecode" of the app in question.

Areas of the brain process read and heard language differently Posted: 07 Mar 2014 05:40 AM PST The brain processes read and heard language differently. Researchers have been able to determine the affected areas of the brain using speech processing tests with the aid of functional magnetic resonance tomography (fMRT).

Talking-therapy treatments to manage osteoarthritis pain Posted: 07 Mar 2014 05:40 AM PST Abnormalities in the way the brain experiences pain may be to blame for the chronic pain suffered by osteoarthritis patients, scientists have shown for the first time. As a results, the researchers suggest that new therapies should target brain mechanisms to enable the brain to cope more effectively with chronic pain, including mindfulness-based talking therapies.

Interactive simulator for vehicle drivers Posted: 07 Mar 2014 05:38 AM PST Maximize mileage, safety, or operating life? Driving behavior behind the wheel has a big influence on the vehicle. Researchers have developed a driving simulator designed to make the 'human factor' more calculable for vehicle engineers.

Effective thermal insulation with wood foam Posted: 07 Mar 2014 05:38 AM PST Insulation materials of tomorrow must be both efficient and environmentally friendly. Scientists are developing insulation foam made from wood that could re- place petrochemical plastics in the long term.

Quicker and cheaper toxicity checking of mussels Posted: 07 Mar 2014 05:38 AM PST A new discovery can make it far easier to check whether mussels have gone bad. Poisonous mussels contain the extremely dangerous and paralyzing neurotoxin saxitoxin. This neurotoxin is the cause of paralytic shellfish poisoning. The first symptoms include numbness in the mouth and lips, spreading to the face and neck. Then, the discomforts come in abundance: headache, dizziness, slurred speech and reduced motor function. The most serious poisonings can lead to fatal paralysis.

Urgent need to study impacts of biomass burning and haze on marine ecosystems in Southeast Asia Posted: 07 Mar 2014 05:38 AM PST Crop residue and forests are burnt in many tropical countries to clear land for agriculture. In Indonesia, annual biomass burning activities cause a widespread smoke-haze phenomenon that affects human health, quality of life and incomes locally and in neighboring countries. While the impacts of these large-scale burning on terrestrial and atmospheric habitats are immediate and obvious, little is known about how adjacent coastal ecosystems such as coral reefs, seagrass and mangroves are affected.

Traffic-related air pollution associated with changes in right ventricular structure, function Posted: 07 Mar 2014 05:37 AM PST Exposure to high levels of traffic-related air pollution is associated with changes in the right ventricle of the heart that may contribute to the known connection between air pollution exposure and heart disease, according to a new study. "The morphologic changes in the right ventricle of the heart that we found with increased exposure to nitrogen dioxide add to the body of evidence supporting a connection between traffic-related air pollution and cardiovascular disease," said the lead author. "The many adverse effects of air pollution on human health support continued efforts to reduce this burden."

Squeezing light into metals: Engineers control conductivity with inkjet printer Posted: 07 Mar 2014 05:37 AM PST Using an inexpensive inkjet printer, electrical engineers produced microscopic structures that use light in metals to carry information. This new technique, which controls electrical conductivity within such microstructures, could be used to rapidly fabricate superfast components in electronic devices, make wireless technology faster or print magnetic materials.

Molecular subtyping of breast cancer can better identify women at high risk of disease recurrence Posted: 06 Mar 2014 06:10 PM PST A method called molecular subtyping can help doctors better determine which of their breast cancer patients are at high risk of getting breast cancer again, a new study reports.

Reducing wait times could improve spinal cord stimulator success for chronic pain Posted: 06 Mar 2014 06:10 PM PST Success rates soared to 75% for patients who waited less than 2 years for a spinal cord stimulator (SCS) implant, compared with 15% for patients whose implants happened 20 years after the onset of pain, according to a retrospective analysis. The length of time patients waited for a referral also varied by specialty.

Drug protects mice against malaria brain damage, raises levels of BDNF in humans Posted: 06 Mar 2014 04:15 PM PST Cerebral malaria is a serious complication of infection with the malaria parasite, affecting approximately one in a thousand children in areas where malaria is common. Many of the patients die, and among those who survive, about a third have lasting cognitive and neurological disabilities, including epilepsy and learning disorders. A new study shows that a known drug can prevent brain damage in a cerebral malaria mouse model and eliminate subsequent neurological deficits.

Fighting for survival in the gut: Unravelling the hidden variation in bacteria Posted: 06 Mar 2014 04:14 PM PST Our intestines harbor an astronomical number of bacteria, around 100 times the number of cells in our body, known as the gut microbiota. These bacteria belong to thousands of species that co-exist, interact with each other and are key to our health. While it is clear that species imbalances may result in disease, it is unclear at what pace does each species in the gut evolves, a process that contributes to the chance of a particular innocuous species becoming harmful to the host.

BPA linked to breast cancer tumor growth Posted: 06 Mar 2014 01:33 PM PST Researchers have attempted to trace how bisphenol-A may promote breast cancer tumor growth with help from a molecule called RNA HOTAIR. "We can't immediately say BPA causes cancer growth, but it could well contribute because it is disrupting the genes that defend against that growth," said a corresponding author on the paper. BPA has been widely used in plastics, such as food storage containers, the lining of canned goods and, until recently, baby bottles. Previous studies have linked BPA to problems with reproductive development, early puberty, obesity and cancers.

Vitamin D increases breast cancer patient survival, study shows Posted: 06 Mar 2014 01:32 PM PST Breast cancer patients with high levels of vitamin D in their blood are twice as likely to survive the disease as women with low levels of this nutrient, report researchers. According to the National Institutes of Health, the current recommended daily allowance for vitamin D is 600 IU for adults and 800 IU for people over 70 years old. The authors urged patients to ask their health care provider to measure their levels before substantially increasing vitamin D intake.

Obese adolescents not getting enough sleep? Posted: 06 Mar 2014 10:04 AM PST Lack of sleep and obesity have been associated with an increased risk of cardiovascular and metabolic diseases in adults and young children. However, the association is not as clear in adolescents, an age group that is known to lack adequate sleep and have an overweight and obesity prevalence rate of 30 percent in the US. Researchers have now found that cardiometabolic risk in obese adolescents may be predicted by typical sleep patterns.

Birds of all feathers and global flu diversity Posted: 06 Mar 2014 10:00 AM PST Scientists have completed the first global inventory of flu strains in birds by reviewing more than 50 published studies and genetic data, providing new insight into the drivers of viral diversity and the emergence of disease that can ultimately impact human health and livelihoods.

Gene important to breast development, breast cancer identified Posted: 06 Mar 2014 10:00 AM PST A gene important to breast development and breast cancer, has been identified, providing a potential new target for drug therapies to treat aggressive types of breast cancer. The research team identified a gene, TAZ, which controls whether breast cells behave more like basal cells or more like luminal cells, information that might be important in understanding and potentially treating certain difficult-to-treat forms of breast cancer. TAZ helps to regulate how different genes operate in different cell types.
