Lead in teeth can tell a body's tale, study finds Posted: 31 Jul 2014 08:09 AM PDT Your teeth can tell stories about you, and not just that you always forget to floss. The discovery could help police solve cold cases, an investigator has said. For instance, if an unidentified decomposed body is found, testing the lead in the teeth could immediately help focus the investigation on a certain geographic area. That way, law enforcement can avoid wasting resources checking for missing persons in the wrong places.

Pervasive implicit hierarchies for race, religion, age revealed by study Posted: 31 Jul 2014 07:25 AM PDT As much as social equality is advocated in the United States, a new study suggests that besides evaluating their own race and religion most favorably, people share implicit hierarchies for racial, religious, and age groups that may be different from their conscious, explicit attitudes and values.

Effect of loud noises on brain revealed in study Posted: 31 Jul 2014 07:25 AM PDT Prolonged exposure to loud noise alters how the brain processes speech, potentially increasing the difficulty in distinguishing speech sounds, according to neuroscientists. Exposure to intensely loud sounds leads to permanent damage of the hair cells, which act as sound receivers in the ear. Once damaged, the hair cells do not grow back, leading to noise-induced hearing loss.

Monoamine oxidase A: Biomarker for postpartum depression Posted: 31 Jul 2014 07:25 AM PDT Postpartum mood swings are correlated with high monoamine oxidase A binding, a study shows. For most women, the birth of their baby is one of the most strenuous but also happiest days in their lives. The vast majority of women experience a temporary drop in mood for a few days after birth. These symptoms of "baby blues" are not an illness; however, in some cases they can represent early signs of an imminent episode of depression: in 13 percent of mothers, the emotional turmoil experienced after childbirth leads to the development of a full-blown postpartum depression.

Breakthrough in understanding of important blood protein Posted: 31 Jul 2014 06:51 AM PDT A previously unknown protein mechanism has now been described by new research. This provides an exceptionally detailed understanding of how nature works, and it can also provide the ability to control nature -- in this case, it is about how coagulated blood can be dissolved, and this can lead to treatment of diseases carrying a risk of blood clots.

Key to aging immune system: Discovery of DNA replication problem Posted: 31 Jul 2014 06:44 AM PDT The immune system ages and weakens with time, making the elderly prone to life-threatening infection and other maladies, and scientists have now discovered a reason why.

Children and hot cars a cause for deadly concern Posted: 31 Jul 2014 06:44 AM PDT Nearly 700 children have lost their lives over the last 20 years in the United States as a result of being left in or playing in a hot car. At last count, the total in the U.S. this year is 18.

Otzi Iceman had genetic predisposition for atherosclerosis: Much the same in ancient peoples as it is today Posted: 30 Jul 2014 05:37 PM PDT While prevalence and types of risk factors for atherosclerosis have varied over time from ancient times to modern society -- such as levels of obesity, physical activity -- genetic predisposition/risk for the condition today appears to be very similar to that in ancient times.

Benefits of e-cigarettes outweigh harms, current evidence suggests Posted: 30 Jul 2014 05:36 PM PDT A major scientific review of available research on the use, content, and safety of e-cigarettes has concluded that -- although long-term health effects of e-cigarette use are unknown -- compared with conventional cigarettes they are likely to be much less harmful to users or bystanders.

How can Britain be made more creative? Posted: 30 Jul 2014 05:35 PM PDT The secret of creativity is not individual genius so much as in the interactions between artists, their peers and their audience, an author says, adding that "people can be made more creative ... through education and through encouragement for the collaborations and groups that might stimulate creative outputs."

Over 80% of patients undergoing interventions for aortic stenosis are in same or better health one year after procedure Posted: 30 Jul 2014 05:35 PM PDT A survey of 13,860 patients who had undergone interventions for aortic valve disease in Germany has revealed that over 80% were in the same or a better state of health one year after the intervention, and was satisfied with the procedural outcome. Aortic stenosis -- the narrowing of the aortic valve in the heart -- is the most frequent valvular heart disease in the aging Western population.

Mechanism promoting multiple DNA mutations described by scientists Posted: 30 Jul 2014 02:31 PM PDT Recent studies have shown that cancer development frequently involves the formation of multiple mutations that arise simultaneously and in close proximity to each other. These groups of clustered mutations are frequently found in regions where chromosomal rearrangements take place. The finding that cancer development often involves multiple mutations arising in clusters and in regions where chromosomal rearrangement takes place may one day lead to new cancer therapies.

Diverticulitis patients reveal psychological, physical symptoms long after acute attacks Posted: 30 Jul 2014 01:15 PM PDT Patients were interviewed by a research team in great detail about the symptoms they experience weeks, months or even years after an acute diverticulitis attack. Their striking findings add to growing evidence that, for some patients, diverticulitis goes beyond isolated attacks and can lead to a chronic condition that mimics irritable bowel syndrome. The researchers used those insights to develop a questionnaire to help doctors better assess the long-term impact of diverticulitis, which ultimately could lead to better understanding and management of the disease.

Pesticide DDT linked to slow metabolism, obesity and diabetes, mouse study finds Posted: 30 Jul 2014 12:17 PM PDT A new study in mice is the first to show that developmental exposure to DDT increases the risk of females later developing metabolic syndrome -- a cluster of conditions that include increased body fat, blood glucose, and cholesterol.

New malaria vaccine candidates identified Posted: 30 Jul 2014 12:11 PM PDT Researchers have discovered new vaccine targets that could help in the battle against malaria. Taking a new, large-scale approach to this search, researchers tested a library of proteins from the Plasmodium falciparum parasite with antibodies produced by the immune systems of a group of infected children.

Fear of losing money, not spending habits, affects investor risk tolerance Posted: 30 Jul 2014 11:10 AM PDT Scientists analyzed the causes of risk tolerance and found that loss aversion, or the fear of losing money, is the primary factor that explains investors' risk tolerance.

Kids with autism and sensory processing disorders show differences in brain wiring Posted: 30 Jul 2014 11:09 AM PDT Researchers have found that children with sensory processing disorders have decreased structural brain connections in specific sensory regions different than those in autism, further establishing SPD as a clinically important neurodevelopmental disorder.

Scientists call for new strategy in pursuit of HIV-free generation Posted: 30 Jul 2014 10:31 AM PDT In light of the recent news that HIV has been detected in the Mississippi baby previously thought to have been cured of the disease, researchers are assessing how to help those born to HIV-infected mothers. These infants around the world are in need of new immune-based protective strategies, including vaccines delivered to mothers and babies and the means to boost potentially protective maternal antibodies, say researchers.

Birthweight and breastfeeding have implications for children's health decades later Posted: 30 Jul 2014 10:24 AM PDT Young adults who were breastfed for three months or more as babies have a significantly lower risk of chronic inflammation associated with cardiovascular and metabolic diseases, according to new research.

Dissolvable fabric loaded with medicine might offer faster protection against HIV Posted: 30 Jul 2014 10:24 AM PDT Bioengineers have discovered a potentially faster way to deliver a topical drug that protects women from contracting HIV. Their method spins the drug into silk-like fibers that quickly dissolve when in contact with moisture, releasing higher doses of the drug than possible with other topical materials.

Appreciation for fat jokes, belief in obese stereotypes linked Posted: 30 Jul 2014 10:24 AM PDT From movies to television, obesity is still considered "fair game" for jokes and ridicule. A new study took a closer look at weight-related humor to see if anti-fat attitudes played into a person's appreciation or distaste for fat humor in the media.

Is a cancer drug working? Modified drug gives a 'green light' for its own success Posted: 30 Jul 2014 07:40 AM PDT A modified anticancer drug can simultaneously target tumor sites and show whether or not it is working.

Toward a home test for detecting potentially dangerous levels of caffeine Posted: 30 Jul 2014 06:43 AM PDT The shocking news of an Ohio teen who died of a caffeine overdose in May highlighted the potential dangers of the normally well-tolerated and mass-consumed substance. To help prevent serious health problems that can arise from consuming too much caffeine, scientists are reporting progress toward a rapid, at-home test to detect even low levels of the stimulant in most beverages and even breast milk.

Older adults are at risk of financial abuse, often from family members Posted: 30 Jul 2014 06:38 AM PDT Nearly one in every 20 elderly American adults is being financially exploited -- often by their own family members. This burgeoning public health crisis especially affects poor and black people. It merits the scrutiny of clinicians, policy makers, researchers, and any citizen who cares about the dignity and well-being of older Americans, says an expert.

Hope for more accurate diagnosis of memory problems Posted: 30 Jul 2014 06:38 AM PDT More accurate tests could be created to diagnose diseases such as Alzheimer's or memory problems stemming from head injuries, leading to earlier intervention, according to new findings.

A blood test could help prevent neural tube birth defects Posted: 29 Jul 2014 07:49 PM PDT A blood test to measure folate concentrations in a mother's red blood cells could help in the prevention of neural tube birth defects, suggests a large study.

Why we should vaccinate boys against HPV as well as girls Posted: 29 Jul 2014 07:49 PM PDT An expert in chronic illnesses says that boys should be vaccinated against the HPV virus, as well as girls, to cut incidence of genital warts and several cancers.

Five daily portions of fruit and vegetables may be enough to lower risk of early death Posted: 29 Jul 2014 07:49 PM PDT Eating five daily portions of fruit and vegetables is associated with a lower risk of death from any cause, particularly from cardiovascular disease, but beyond five portions appears to have no further effect, finds a new study.

Eating tree nuts results in 'modest decreases' in blood fats and sugars, survey finds Posted: 29 Jul 2014 07:49 PM PDT Eating tree nuts appears to help reduce two of the five markers for metabolic syndrome, a group of factors that raise the risk for heart disease and other health problems such as diabetes and strokes, a new research paper says.
