Impulsive personality linked to food addiction Posted: 24 Jan 2014 01:12 PM PST The same kinds of impulsive behavior that lead some people to abuse alcohol and other drugs may also be an important contributor to an unhealthy relationship with food, according to new research.

New study changes conceptions about the determinants of skull development and form Posted: 24 Jan 2014 01:12 PM PST A new study offers surprising insights into dietary influences on the growing skull.

Psychologists document the age our earliest memories fade Posted: 24 Jan 2014 10:57 AM PST Although infants use their memories to learn new information, few adults can remember events in their lives that happened prior to the age of three. Psychologists have now documented that age seven is when these earliest memories tend to fade into oblivion, a phenomenon known as "childhood amnesia." The study is the first empirical demonstration of the onset of childhood amnesia, and involved interviewing children about past events in their lives.

Study expands cancer genomics universe Posted: 24 Jan 2014 08:57 AM PST By analyzing the genomes of thousands of patients' tumors, a research team has discovered many new cancer genes -- expanding the list of known genes tied to these cancers by 25 percent. The team's work, which lays a critical foundation for future cancer drug development, also shows that creating a comprehensive catalog of cancer genes for scores of cancer types is feasible with as few as 100,000 patient samples.

Do doctors spend too much time looking at computer screen? Posted: 24 Jan 2014 08:57 AM PST When physicians spend too much time looking at the computer screen in the exam room, nonverbal cues may get overlooked and affect doctors' ability to pay attention and communicate with patients, according to a study.

Aspirin intake may stop growth of tumors that cause hearing loss Posted: 24 Jan 2014 08:07 AM PST Researchers have demonstrated, for the first time, that Aspirin intake correlates with halted growth of vestibular schwannomas (also known as acoustic neuromas), a sometimes lethal intracranial tumor that typically causes hearing loss and tinnitus.

When hospitals share patient records, emergency patients benefit, study suggests Posted: 24 Jan 2014 07:19 AM PST As hospitals and doctors' offices across the country race to join online systems that let them share medical information securely, a new study suggests that these systems may already be helping cut unnecessary care. Fewer emergency patients got repeated medical scans when they went to a hospital that takes part in a health information exchange,according to new findings.

Do religious people love their neighbors? Yes, some neighbors, study finds Posted: 24 Jan 2014 06:37 AM PST Most religions teach their followers to "Love thy neighbor" -- including those of different races or beliefs. But is religiousness really related to love of neighbors? A study provides partial support for that idea.

40 percent of parents learn how to use technology from their children Posted: 24 Jan 2014 05:27 AM PST Scientists have found that youth influence their parents in all technologies studied (computer, mobile Internet, social networking) up to 40 percent of the time. The children's scores were higher compared to parents, showing that parents don't necessarily recognize the influence.

Simple amoeba holds the key to better treatment for Alzheimer's disease Posted: 24 Jan 2014 05:27 AM PST Scientists have discovered the use of a simple single-celled amoeba to understand the function of human proteins in causing Alzheimer's disease.

The scent of cancer: Detecting cancer with fruit fly's antenna Posted: 24 Jan 2014 05:27 AM PST Researchers have, for the first time, detected cancer cells using the olfactory senses of fruit flies.

A treasure trove of Arabic terms Posted: 24 Jan 2014 05:26 AM PST Are the terms alcohol and kohl related? Yes, if we trace their origins. An Arabic etymological term base, the first of its kind, can provide new knowledge about Arab identity and cultural history.

New cause identified for children, adults with joint, skeletal, skin problems Posted: 24 Jan 2014 05:26 AM PST Scientists have identified the cause of a rare condition called Leri's pleonosteosis (LP). LP is an inherited condition in which children are born with contractures of multiple joints and then develop difficulty of joint movements that progress in severity with age. The research team showed that extra genetic material on chromosome number 8 caused the condition in two families from Manchester.

The shape of infectious prions Posted: 24 Jan 2014 05:26 AM PST Prions are unique infective agents -- unlike viruses, bacteria, fungi and other parasites, prions do not contain either DNA or RNA. Despite their seemingly simple structure, they can propagate their pathological effects like wildfire, by "infecting" normal proteins. PrPSc (the pathological form of the prion protein) can induce normal prion proteins (PrPC) to acquire the wrong conformation and convert into further disease-causing agents.

New computer model may aid personalized cancer care Posted: 24 Jan 2014 05:23 AM PST Scientists have developed a mathematical model to predict how a patient's tumor is likely to behave and which of several possible treatments is most likely to be effective.

Generation blame: How age affects our views of anti-social behavior Posted: 23 Jan 2014 07:23 PM PST Research reveals disconnect between what adults and young people interpret as anti-social behavior (ASB), as 40 percent of adults see young people gathering in public as ASB. Study is the first to directly compare teenage perceptions of ASB with those of adults.

Evolution of drug resistance within a HIV population Posted: 23 Jan 2014 07:20 PM PST A new study found that in some patients a resistance mutation to a particular drug appeared in a single virus particle, which then rapidly proliferated until the entire viral population within the patient consisted of its progeny and was also resistant to the drug. In other patients the same resistance mutation occurred in multiple viral particles within a short window of time, which led to a more heterogeneous, but still drug-resistant, viral population.

The rocky road to a better flu vaccine Posted: 23 Jan 2014 07:20 PM PST Currently approved flu vaccines are less effective in the elderly, yet an estimated 90 percent of influenza-related deaths occur in people over 65.

A thousand years ago, Central Europeans digested milk as well as us today Posted: 23 Jan 2014 07:19 PM PST Back in the Middle Ages, Central Europeans were already capable of digesting milk, yogurt and cheese just as well as most people of European descent are today. Researchers have discovered that the population of the medieval town of Dalheim had a similar genetic predisposition for milk digestion to present-day Germans and Austrians. Moreover, the study reveals that lactose tolerance was more widespread than previously believed.

Lab-grown, virus-free stem cells repair retinal tissue in mice Posted: 23 Jan 2014 07:19 PM PST Investigators have developed human induced-pluripotent stem cells (iPSCs) capable of repairing damaged retinal vascular tissue in mice. The stem cells, derived from human umbilical cord-blood and coaxed into an embryonic-like state, were grown without the conventional use of viruses, which can mutate genes and initiate cancers, according to the scientists. Their safer method of growing the cells paves the way for a stem cell bank of cord-blood derived iPSCs to advance regenerative medicine research.

Are developing heart valves sensitive to environmental chemicals? Posted: 23 Jan 2014 01:18 PM PST Exposure to environmental endocrine disrupters, such as bisphenol A, which mimic estrogen, is associated with adverse health effects. Bisphenol A is commonly found in plastic bottles and plastic food containers. New research from on the effects of these chemicals on zebrafish shows that embryonic heart valves could be particularly in danger.

Super bowl ads score with popular music Posted: 23 Jan 2014 01:18 PM PST Researchers are wrapping up a 10-year study of popular music in Super Bowl commercials this year. Through this research they will illustrate the frequency in which advertisers employ popular music to market and relate with consumers.

Sports medicine physical of future could help athletes 'ESCAPE' sudden cardiac death Posted: 23 Jan 2014 12:48 PM PST A young athlete in seemingly excellent health dies suddenly from a previously undetected cardiovascular condition such as hypertrophic cardiomyopathy in nearly every US state annually. Although these conditions can be detected using electrocardiography (ECG) during a screening exam, the American Heart Association recommends against routine use of ECG, because it has a high false-positive rate.

Depression symptoms, emotional support impact PTSD treatment progress, study finds Posted: 23 Jan 2014 12:48 PM PST Researchers found that during PTSD treatments, rapid improvements in depression symptoms are associated with better outcomes.

Doctors implant first new valve device in heart patient after FDA approval Posted: 23 Jan 2014 12:47 PM PST American doctors yesterday became the first to use a new minimally invasive medical device since it received FDA approval last week. The device treats patients with severely damaged aortic heart valves who are too ill or frail to have their aortic valves replaced through traditional open-heart surgery.

Liars find it more rewarding to tell truth than fib when deceiving others Posted: 23 Jan 2014 12:47 PM PST A report based on two neural imaging studies that monitored brain activity has found individuals are more satisfied to get a reward from telling the truth rather than getting the same reward through deceit.

Gap in life expectancy between rural, urban residents is growing Posted: 23 Jan 2014 12:47 PM PST A new study finds that rural American residents have experienced smaller gains in life expectancy than their urban counterparts and the gap continues to grow.

Moderate doses of radiation therapy to unaffected breast may prevent second breast cancers Posted: 23 Jan 2014 11:20 AM PST Survivors of breast cancer have a one in six chance of developing breast cancer in the other breast. But a study conducted in mice suggests that survivors can dramatically reduce that risk through treatment with moderate doses of radiation to the unaffected breast at the same time that they receive radiation therapy to their affected breast. The treatment, if it works as well in humans as in mice, could prevent tens of thousands of second breast cancers.

National plan for preventing healthcare-associated infections shows progress Posted: 23 Jan 2014 11:20 AM PST Independent evaluators have found that measurable progress in reducing the rates of some targeted HAIs has been achieved under the umbrella of a national plan to prevent HAIs that was developed by the US Department of Health and Human Services.

Donors should have access to their own raw data provided to biobanks Posted: 23 Jan 2014 11:20 AM PST Scientists have called for data held in biobanks to be made accessible to the people donating material and data to them.

Salmonella infection mitigates asthma Posted: 23 Jan 2014 09:59 AM PST Researchers have identified the mechanism by which Salmonella infections can reduce the incidence of asthma in mice. The research opens up new avenues of research that could lead to treatments.

Two proteins compete for one port on a growth factor; one promotes metastasis, the other blocks it Posted: 23 Jan 2014 09:58 AM PST Consider two drivers, each with a key that fits the same car. Driver 1 wants simply to turn on the ignition and leave the vehicle idling, ready and waiting to roll. Driver 2 wants to take it on a destructive joy ride. New cancer researchers have discovered that the same happens in our bodies between two proteins.

What makes cell division accurate? Posted: 23 Jan 2014 09:55 AM PST Losing or gaining chromosomes during cell division can lead to cancer and other diseases, so understanding mitosis is important for developing therapeutic strategies. New research focused on one important part of this process. The results improve our understanding of how cell division gives rise to two daughter cells with an equal complement of chromosomes.

Obesity in mothers alters babies' weight through brain rewiring Posted: 23 Jan 2014 09:55 AM PST Obese mothers are more likely to have children with metabolic disorders, but the underlying reasons for this effect have been unclear. A new study reveals that the offspring of mouse mothers on a high-fat diet are predisposed to obesity and diabetes because of abnormal neuronal circuits in the hypothalamus. The findings suggest that mothers who consume a large amount of fat during the third trimester may be putting their children at risk for lifelong obesity.

A time for memories: How the brain determines the timing at which neurons in specific areas fire to create memories Posted: 23 Jan 2014 09:54 AM PST Neuroscientists have discovered how the brain determines the timing at which neurons in specific areas fire to create new memories. This research exploits the unique opportunity of recording multiple single-neurons in patients suffering from epilepsy refractory to medication that are implanted with intracranial electrodes for clinical reasons.

Scientists find regulator of amyloid plaque buildup in alzheimer's disease Posted: 23 Jan 2014 09:53 AM PST Scientists have identified a critical regulator of a molecule deeply involved in the progression of Alzheimer's disease.

Telling the whole truth may ease feelings of guilt Posted: 23 Jan 2014 04:57 AM PST People feel worse when they tell only part of the truth about a transgression compared to people who come completely clean, according to new research.

Long-term spinal cord stimulation stalls symptoms of parkinson's-like disease Posted: 23 Jan 2014 04:54 AM PST Researchers have shown that continuing spinal cord stimulation appears to produce improvements in symptoms of Parkinson's disease, and may protect critical neurons from injury or deterioration.

Major South African trial did not improve tuberculosis control in gold mines Posted: 22 Jan 2014 05:22 PM PST A major trial aiming to cut the rate of tuberculosis among South Africa's gold miners did not reduce the number of cases or deaths from the disease, according to a study.
