Gut microbes affect circadian rhythms and metabolism in mice Posted: 03 Aug 2015 06:27 PM PDT A new study found evidence that gut microbes affect circadian rhythms and metabolism in mice.

Frequent travel is damaging to health and wellbeing, according to new study Posted: 03 Aug 2015 06:25 PM PDT Researchers investigated how frequent, long-distance travel is represented in mass and social media. They found that the images portrayed do not take into account the damaging side effects of frequent travel such as jet-lag, deep vein thrombosis, radiation exposure, stress, loneliness and distance from community and family networks.

Marriage can lead to dramatic reduction in heavy drinking in young adults Posted: 03 Aug 2015 06:25 PM PDT Research on alcohol-use disorders consistently shows problem drinking decreases as we age. Now, researchers have found evidence that marriage can cause dramatic drinking reductions even among people with severe drinking problems. Scientists believe findings could help improve clinical efforts to help these people, inform public health policy changes and lead to more targeted interventions for young adult problem drinkers.

What would the world look like to someone with a bionic eye? Posted: 03 Aug 2015 12:52 PM PDT While major advancements have been made in vision recovery technologies, the vision provided by those devices might be very different from what scientists and patients have assumed.

The uneasy, unbreakable link of money and medicine Posted: 03 Aug 2015 12:51 PM PDT After centuries of concerns about the potentially compromising role of money in medicine, the debate remains irreconcilable and the link remains indivisible, a new article suggets. Even the reforms of Obamacare, the author writes, may not change much.

Are animal models still essential to biological research? Posted: 03 Aug 2015 12:51 PM PDT A new article covers the use of animal models in scientific research. The use of animals in scientific research prompts regular debate and it can be difficult to garner a clear picture of the actual need for animal models.

Potential new therapy approaches to reverse kidney damage identified Posted: 03 Aug 2015 08:12 AM PDT Cell plasticity program resulting from kidney damage can be targeted to reverse kidney disease and fibrosis, new research suggests. The study demonstrated the importance of an embryonic cellular process called EMT (epithelial-to-mesenchymal transition) as a potential therapeutic target for reversing kidney disease. Embryos cannot develop without EMT.

How an important enzyme used in drug production recognizes its substrate Posted: 03 Aug 2015 07:51 AM PDT The mechanism by which an enzyme used in industrial production of an important drug for type-2 diabetes recognizes its target has been demonstrated by a group of researchers. This finding will further design of novel biocatalysts for industrial production of chiral amine compounds, crucial building blocks in the synthesis of some pharmaceutical drugs.

Brain teaser: 3-D printed 'tissue' to help combat disease Posted: 03 Aug 2015 07:30 AM PDT A bench-top brain that accurately reflects actual brain tissue would be significant for researching not only the effect of drugs, but brain disorders like schizophrenia, and degenerative brain disease. Researchers have now completed 3-D printing a six-layered structure similar to brain tissue, in which cells are accurately placed and remain in their designated layer.

Yo-yo dieting not associated with increased cancer risk Posted: 03 Aug 2015 07:29 AM PDT The first comprehensive study of its kind finds weight cycling, repeated cycles of intentional weight loss followed by regain, was not associated with overall risk of cancer in men or women.

Combination therapy may be more effective against the most common ovarian cancer Posted: 03 Aug 2015 05:37 AM PDT High-grade serous ovarian cancer often responds well to the chemotherapy drug carboplatin, but why it so frequently comes back after treatment has been a medical mystery. Now a team of researchers has discovered that a subset of tumor cells that don't produce the protein CA125, a biomarker used to test for ovarian cancer, has an enhanced ability to repair their DNA and resist programmed cell death — which allows the cells to evade the drug and live long enough to regrow the original tumor.

Computer games can pick up dyslexia in minority pupils Posted: 03 Aug 2015 05:35 AM PDT While pupils from minority groups are over-represented in Norwegian special needs education, practically no children from these groups are diagnosed with dyslexia. As a consequence many miss out on important help. Researchersare studying whether a computer game can pick up dyslexia in pupils from minority groups.

New survey enhances precision of distinguishing between expectable vs. worrisome early childhood misbehavior Posted: 03 Aug 2015 05:35 AM PDT Researchers are using a novel dimensional method for distinguishing misbehavior that is expectable in early childhood versus that which is cause for clinical concern. Using a survey developed by the researchers to enhance precision of clinical identification in early childhood the Multidimensional Assessment Profile of Disruptive Behavior (MAP-DB), scientists obtained mothers' reports of their preschoolers' irritability at multiple time points. They used these irritability patterns to predict which preschoolers would exhibit problems that interfered with their ability to regulate their behavior and learning and participate in daily life activities.

Proving nanoparticles in sunscreen products Posted: 03 Aug 2015 05:34 AM PDT Loads of cosmetics like sunscreen lotions contain titanium dioxide. These nanoparticles are contentious. Experts suspect they may have harmful effects on people and the environment. But it is difficult to prove that the particles are in the lotions. Using a new method, these particles can now be calculated.

If you're using drugs, scientists want to help you avoid addiction Posted: 03 Aug 2015 05:33 AM PDT Abstinence is the best way to avoid drug addiction. But in many societies, drug use is the norm, not the exception, especially by youth. What keeps the majority of users from becoming addicted? How drugs are taken has something to do with it, according to pharmacology researchers.

Study sheds surprising light on the causes of cerebral palsy Posted: 03 Aug 2015 05:33 AM PDT Cerebral palsy is the most common cause of physical disability in children. It has historically been considered to be caused by factors such as birth asphyxia, stroke and infections in the developing brain of babies. In a new game-changing study, a research team has uncovered strong evidence for genetic causes of cerebral palsy that turns experts' understanding of the condition on its head.

Common medications for dementia could cause harmful weight loss Posted: 03 Aug 2015 05:33 AM PDT Medications commonly used to treat dementia could result in harmful weight loss, according to researchers, and clinicians need to account for this risk when prescribing these drugs to older adults, they say.

Urine test for early stage pancreatic cancer possible after biomarker discovery Posted: 03 Aug 2015 05:33 AM PDT A combination of three proteins found at high levels in urine can accurately detect early-stage pancreatic cancer, researchers have found. The discovery could lead to a non-invasive, inexpensive test to screen people at high risk of developing the disease.

Even moderate picky eating can have negative effects on children's health Posted: 03 Aug 2015 05:33 AM PDT Picky eating among children is a common but burdensome problem that can result in poor nutrition for kids, family conflict, and frustrated parents. Although many families see picky eating as a phase, a new study finds moderate and severe picky eating often coincides with serious childhood issues such as depression and anxiety that may need intervention.

Want to boost your toddler's development? Put a toy chicken on your head Posted: 02 Aug 2015 05:44 PM PDT Parents who joke and pretend with their children are teaching them important life skills, research has revealed. The study showed that children as young as 16 months old naturally learn the difference between joking and pretending by picking up on their parents' cues. It also showed understanding the difference between the two allows children the opportunity to learn, imagine, bond, and think in abstract ways.

'Brain training' app may improve memory, daily functioning of people with schizophrenia Posted: 02 Aug 2015 05:44 PM PDT A 'brain training' iPad game may improve the memory of patients with schizophrenia, helping them in their daily lives at work and living independently, according to new research.

Gout medications might be useful in treating alcohol-induced liver disease Posted: 31 Jul 2015 03:26 PM PDT Two commonly used gout medications, which target uric acid and adenosine triphosphate, may offer protection from alcohol-induced liver disease and inflammation, new research suggests. These findings suggest that clinical trials in humans with alcoholic liver disease should be considered.
