11:30 PM | Married Couples Who Smoke Pot Have Fewer Domestic Violence Incidents
A look at 634 couples found that the more often they smoked marijuana, the less likely they were to engage in domestic violence.   The scholars attempted to clarify inconsistent findings about domestic violence among pot-smoking couples that primarily has been based on cross-sectional data (i.e., data from one point in time). Looking at couples over the first nine years of marriage, the study found: More frequent marijuana use by husbands and wives (two-to-three times per month or […]

11:06 PM | Holographic Noise Speculation: Maybe You Are A 2-D Hologram
The Holometer, an experiment at Fermi National Accelerator Laboratory, has started collecting data but researchers are not going to wait to start their media blitz; they are throwing out  mind-bending speculation, like that perhaps we live in a hologram. Much like characters on a television show would not know that their seemingly 3-D world exists only on a 2-D screen, we could be clueless that our 3-D space is just an illusion. The information about everything in our universe […]

10:17 PM | Ionic Liquids: Busting Through Biofilm Shatters Defenses Of Serious Skin Infections
Biofilms are the first line of defense for harmful bacteria and make the treatment of skin infections especially difficult because microorganisms protected in a biofilm have antibiotic resistance and recalcitrance to treatment. Biofilm-protected bacteria account for some 80 percent of total bacterial infections in humans and are 50 to 1,000 times more resistant to antibiotics than simpler bacterial infections.  Biofilms often persist in the periphery of an actual wound, beneath an […]

9:01 PM | Sorting Cells With Sound
Researchers have devised a new way to separate cells by exposing them to sound waves as they flow through a tiny channel. Separating cells with sound offers a gentler alternative to existing cell-sorting technologies, which require tagging the cells with chemicals or exposing them to stronger mechanical forces that may damage them. Their device, about the size of a dime, could be used to detect the extremely rare tumor cells that circulate in cancer patients' blood, helping doctors predict […]

8:38 PM | Resilience Management: What The Bubonic Plague Can Teach Us About Ebola
In the 14th century, Venice was in many ways still a world power in its own right. The days when it could topple kingdoms using commerce were behind it, but it was still an important trade destination. In that period, trade meant ports and ports meant the Bubonic Plague in 1347. When it hit, some tried prayer, some tried hunting vampires, but then officials quickly began to utilize what we would now call resilience management: rather than trying to target a poorly understood […]

Growing nerve tissue and organs is a sci-fi dream. I met the pioneering researcher who grew eyes and brain cellsThe train line from mainland Kobe is a marvel of urban transportation. Opened in 1981, Japans first driverless, fully automated train pulls out of Sannomiya station, guided smoothly along elevated tracks that stand precariously over the bustling city streets below, across the bay to the Port Island.The island, and much of the city, was razed to the ground in the Great Hanshin […]

6:31 PM | Disillusioned Churchgoers Undergo A Moral Identity Crisis
Dsillusioned churchgoers may find it increasingly difficult to remain associated with their church, yet many also find it difficult to leave.  They have not only a moral identity crisis but deep identity crises as their most important relationships and beliefs are put at risk.  The authors of a paper in the Journal of Consumer Research conducted interviews with people who identify as former churchgoers and asked them to reflect on their experiences in leaving the church and the […]

Sensory neurons receive input from the outside world and send these signals on to the rest of the nervous system. This makes the concept of ‘silence’ fairly intriguing: what happens when there is very little sensory signal for the rest … Continue reading →

4:31 PM | Do Moviegoers Prefer Fact Or Fiction? The Surprising Answer
Do you feel sadder watching a documentary about war or a drama about a young person dying of cancer? If you poll most people, they will say there are stronger emotional reactions when stories are based on true events rather than fiction, but a new analysis in the Journal of Consumer Research finds that is not so.read more

4:30 PM | Outsourcing Parenthood: It Takes The Marketplace To Raise A Child
How did our ancestors raise so many kids, while modern parents struggle with the fast pace of life? It's unclear, but to help solve such First World problems, many businesses now offer traditional caregiving services ranging from planning birthday parties to teaching children how to ride a bike. According to a new paper in the Journal of Consumer Research, by outsourcing traditional parental duties, modern-day parents feel they are ultimately protecting parenthood. To determine the role of the […]

3:54 PM | An Inconvenient Truth: Green Behavior Benefits Corporations More Than Society
In the world of mixed environmental and social problems, such as global warming policy, there is a tug of war between social authoritarian forces that want top-down laws and regulations and behavior control, and a grass roots strategy that believes awareness and people making better consumption choices will be superior. A paper in the Journal of Consumer Research is evidence for the social authoritarians. It finds that responsible consumption shifts the burden for solving global problems […]

3:45 PM | Key To Speed? Elite Sprinters Maximize Force To Ground
The world's fastest sprinters have unique gait features that account for some of their ability to achieve fast speeds, according to two new studies which indicate that the secret to elite sprinting speeds lies in the distinct limb dynamics sprinters use to elevate ground forces upon foot-ground impact. The new findings address a major performance question that has remained unanswered for more than a decade.read more

3:16 PM | Link Between Prenatal Antidepressant Exposure And Autism Risk Questioned
Some epidemiological papers have linked an increased risk of autism in children with women who took antidepressants during pregnancy. Suggestions have been that antidepressants or severe maternal depression cause autism. In a Molecular Psychiatry paper, investigators from Massachusetts General Hospital report that while a diagnosis of autism spectrum disorder was more common in the children of mothers prescribed antidepressants during pregnancy than in those with no prenatal exposure, when the […]

3:00 PM | Carbon And Biomass: Earth Can Sustain More Plant Growth Than Estimates Showed
A new analysis suggests the planet can produce much more land-plant biomass – the total material in leaves, stems, roots, fruits, grains and other terrestrial plant parts – than previous estimates showed. In modeling, earth scientists tend to make a lot of simplifying assumptions, and one of those assumptions has been that biomass of now will be biomass of the future, which is in defiance of both science and history. A new paper in Environmental Science and Technology recalculates […]

2:41 PM | Wave-Particle Duality Principle Remains Safe And Sound
Wave-particle duality suggests that elementary particles, like electrons and photons, cannot be completely described as either waves or particles, because they exhibit both types of properties. In the double-slit experiment, observing a photon pass through one of the two slits is an example of a particle-like property; a particle can only pass through one or the other. When two waves converge to form an interference pattern, the photon must have passed through both slits simultaneously—a […]

2:21 PM | Eating Disorders Correlated To Increased Risk Of Autoimmune Diseases
Researchers recently set out to determine the prevalence and incidence of autoimmune diseases in people with anorexia nervosa, bulimia nervosa and binge eating disorder.  Patients (N=2342) treated at the Eating Disorder Unit of Helsinki University Central Hospital between 1995 and 2010 were compared with general population controls (N=9368) matched for the age, sex and place of residence. Data of 30 autoimmune diseases were from the Hospital Discharge Register from 1969 to 2010.read more

1:31 PM | X-Rays Only Detect 20 Percent Of Lung Cancer Cases
Current x-ray examinations capture only 20 percent of cases but there is a better way, according to Norwegian researchers. With modern ultra low-dose CT, that number climbs to 90 percent.In lung cancer, the prognosis is poor. In Norway, 85 percent of lung cancer patients die within five years, the authors say, and what is unfortunate is that the tumor can grow for a long time before even being detected. Most patients have their first diagnosis made by x-ray imaging.Yet no one had investigated […]

1:01 PM | Do Closed-Loop Insulin Delivery Systems Improve Blood Glucose Control In Type 1 Diabetes?
In a closed-loop control approach to managing type 1 diabetes, glucose sensors placed under the skin continuously monitor blood sugar levels, triggering the release of insulin from an implantable insulin pump as needed. The aim of this closed-loop insulin delivery system is improved control of blood glucose levels throughout the day and night. But a new study in adults and adolescents found that mean blood glucose levels remained at safe levels 53-82% of the time, according to the results […]
