Being rude to your child's doctor could lead to worse care Posted: 12 Jan 2017 12:36 PM PST Emotions tend to run high in hospitals, and patients or patients' loved ones can be rude to medical professionals when they perceive inadequate care. Investigators warn though, that being rude may lead to worse care for your child.

Master regulator of cellular aging discovered Posted: 12 Jan 2017 11:13 AM PST Scientists have discovered a protein that fine-tunes the cellular clock involved in aging.

Decreasing cocaine use leads to regression of coronary artery disease Posted: 12 Jan 2017 11:13 AM PST People who use cocaine regularly are at high risk of coronary artery disease. A study now reports that stopping or reducing cocaine use can potentially reverse the process of coronary atherosclerosis.

'Mysterious' non-protein-coding RNAs play important roles in gene expression Posted: 12 Jan 2017 11:13 AM PST Enhancers boost the rate of gene expression from nearby protein-coding genes so a cell can pump out more of a needed protein molecule. A mysterious subset of non-coding RNAs -- enhancer RNAs (eRNAs) are transcribed from enhancer sequences. Shedding new light on these elusive eRNAs, researchers showed that CBP, an enzyme that activates transcription from enhancers, binds directly to eRNAs to control patterns of gene expression by acetylation.

Study outlines framework for identifying disease risk in genome sequence Posted: 12 Jan 2017 11:13 AM PST Imagine a day when you visit the doctor's office for your annual physical. Your physician orders routine tests -- cholesterol, glucose and blood count -- but they also order a sequence of your genome, all 3 billion letters of it. Routine genomic testing is not far away, according to researchers.

Crybaby: The vitamins in your tears Posted: 12 Jan 2017 11:13 AM PST Would you rather shed a couple tears or have your blood drawn? Testing for nutritional deficiencies in blood can be invasive and expensive. Researchers explored what it takes to switch to tears instead and their study focuses on the nutritional connection between infants and parents.

Improving longevity of functionally integrated stem cells in regenerative vision therapy Posted: 12 Jan 2017 11:12 AM PST One of the challenges in developing stem cell therapies is ensuring that transplanted cells can survive long enough to work. Researchers report one of the first demonstrations of long-term vision restoration in blind mice by transplanting photoreceptors derived from human stem cells and blocking the immune response that causes transplanted cells to be rejected. The findings support a path to improving clinical applications in restoring human vision lost to degenerative eye diseases.

Biologists discover how viruses hijack cell's machinery Posted: 12 Jan 2017 11:12 AM PST Biologists have documented for the first time how very large viruses reprogram the cellular machinery of bacteria during infection to more closely resemble an animal or human cell -- a process that allows these alien invaders to trick cells into producing hundreds of new viruses, which eventually explode from and kill the cells they infect.

Wearable biosensors can flag illness, Lyme disease, risk for diabetes; low airplane oxygen Posted: 12 Jan 2017 11:11 AM PST Can your smart watch detect when you are becoming sick? A new study indicates that this is possible. By following 60 people through their everyday lives, researchers found that smart watches and other personal biosensor devices can help flag when people have colds and even signal the onset of complex conditions like Lyme disease and diabetes.

Researchers create mosquito resistant to dengue virus Posted: 12 Jan 2017 11:11 AM PST Researchers have genetically modified mosquitoes to resist infection from dengue virus, a virus that sickens an estimated 96 million people globally each year and kills more than 20,000, mostly children.

Cholera bacteria infect more effectively with a simple twist of shape Posted: 12 Jan 2017 10:01 AM PST The bacteria behind the life-threatening disease cholera initiates infection by coordinating a wave of mass shapeshifting that allows them to more effectively penetrate their victims' intestines, researchers have found. The researchers also identified the protein that allows Vibrio cholerae to morph, and found that it's activated through quorum sensing. The findings could lead to new treatments for cholera that target the bacteria's ability to change shape or penetrate the gut.

How well do we understand the relation between incorrect chromosome number, cancer? Posted: 12 Jan 2017 10:01 AM PST Researchers report surprising results of experiments intended to explore the consequences of having too many or too few chromosomes, a phenomenon that biologists call aneuploidy. They were surprised to find that having one extra chromosome actually supresses cancer, contrary to long-held belief.

Exercise ... It does a body good: 20 minutes can act as anti-inflammatory Posted: 12 Jan 2017 08:57 AM PST It's well known that regular physical activity has health benefits, including weight control, strengthening the heart, bones and muscles and reducing the risk of certain diseases. Recently, researchers have found how just one session of moderate exercise can also act as an anti-inflammatory. The findings have encouraging implications for chronic diseases like arthritis, fibromyalgia and for more pervasive conditions, such as obesity.

Affordable water in the US: A burgeoning crisis Posted: 12 Jan 2017 08:08 AM PST If water rates continue rising at projected amounts, the number of US households unable to afford water could triple in five years, to nearly 36 percent, finds new research.

Advanced metastatic midgut neuroendocrine tumors: New drug in development shows improved progression-free survival for patients Posted: 12 Jan 2017 08:08 AM PST A new therapy in development for the treatment of midgut neuroendocrine tumors, a rare type of cancer that occurs in the small intestine and colon, shows improved progression-free survival and response rates for patients with advanced disease.

Viruses in genome important for our brain Posted: 12 Jan 2017 08:08 AM PST Over millions of years retroviruses have been incorporated into our human DNA, where they today make up almost 10 per cent of the total genome. A research group has now discovered a mechanism through which these retroviruses may have an impact on gene expression. This means that they may have played a significant role in the development of the human brain as well as in various neurological diseases.

Exercise, diet could offset effects of malaria, study shows Posted: 12 Jan 2017 08:08 AM PST The right amount of diet and exercise can help lessen damage to the heart and skeletal muscles brought on by malaria, according to a new study.

Miami doctors publish study of first locally-acquired Zika transmission Posted: 12 Jan 2017 08:08 AM PST Following the recent Zika outbreak in Miami-Dade County, a multidisciplinary team of physicians has published a case study describing in detail the nation's first locally-transmitted case of Zika.

Target freshers to halt spread of meningitis, say researchers Posted: 12 Jan 2017 08:08 AM PST A campaign targeted at students arriving at university for the first time could hold the key to reducing the spread of meningitis and septicemia, say researchers in England.

CRISPR gene editing takes on rare immunodeficiency disorder Posted: 12 Jan 2017 08:07 AM PST Researchers have harnessed the CRISPR-Cas9 technology to correct mutations in the blood stem cells of patients with a rare immunodeficiency disorder; the engineered cells successfully engrafted in mice for up to five months.

Sharing of data to combat infectious disease outbreaks Posted: 12 Jan 2017 05:50 AM PST To protect people against potentially deadly infectious disease outbreaks, it is critical that scientists and governments rapidly share information about the pathogens that cause them. A new shows how it is possible to encourage the greater international sharing of such data, despite numerous challenges that exist.

Yoga may have health benefits for people with chronic non-specific lower back pain Posted: 11 Jan 2017 06:32 PM PST Yoga may lead to a reduction in pain and functional ability in people with chronic non-specific lower back pain over the short term, compared with no exercise, a new systematic review suggests. However, researchers advise that more studies are needed to provide information on long-term effects.
