Electromagnetics Without Leaks - Like Throwing Pebbles In A Pond With No Splash

Electromagnetics Without Leaks - Like Throwing Pebbles In A Pond With No Splash

Physicists have found a radical new way confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash. It appears to contradict a fundamental tenet of electrodynamics, that accelerated charges create electromagnetic radiation, said lead researcher Dr. Andrey Miroshnichenko from The Australian National University (ANU).
"This problem has puzzled many people. It took us a year to get this concept clear in our heads," said Miroshnichenko, from the ANU Research School of Physics and Engineering. "Ever since the beginning of quantum mechanics people have been looking for a configuration which could explain the stability of atoms and why orbiting electrons do not radiate." 

Life Expectancy Has Risen - Now How To Reduce Age-Related Illness And Disability

Life Expectancy Has Risen - Now How To Reduce Age-Related Illness And Disability

People around the world are living longer, even in some of the poorest countries, but a complex mix of fatal and nonfatal ailments causes a tremendous amount of health loss, according to a new analysis of all major diseases and injuries in 188 countries.
Thanks to marked declines in death and illness caused by HIV/AIDS and malaria in the past decade and significant advances made in addressing communicable, maternal, neonatal, and nutritional disorders, health has improved significantly around the world. Global life expectancy at birth for both sexes rose by 6.2 years (from 65.3 in 1990 to 71.5 in 2013), while healthy life expectancy, or HALE, at birth rose by 5.4 years (from 56.9 in 1990 to 62.3 in 2013).

Shifting Focus From Calories To Nutritional Value: New Fad Or Sound Science?

Shifting Focus From Calories To Nutritional Value: New Fad Or Sound Science?

It's time to stop counting calories and start promoting the nutritional value of foods, according to an editorial in Open Heart. 
Drs Aseem Malhotra and James DiNicolantonio, and Professor Simon Capewell, argue that rather like stopping smoking, simple dietary changes can rapidly improve health outcomes at the population level.  They believe this will more rapidly cut illness and death from cardiovascular disease and curb the rising tide of obesity. For example, boosting omega 3 fatty acid (from fatty fish), olive oil, and nut intake have all been associated with reductions in deaths from all causes and from cardiovascular disease, within months, they say.

Daratumumab Immunotherapy Agent Benefits Patients With Drug-Resistant Multiple Myeloma

Daratumumab Immunotherapy Agent Benefits Patients With Drug-Resistant Multiple Myeloma

In its first clinical trial, an antibody therapy produced at least partial remissions in a third of patients with multiple myeloma who had exhausted multiple prior treatments, investigators at Dana-Farber Cancer Institute and other organizations have reported.
The drug, daratumumab, proved generally safe in patients, even at the highest doses tested in the study. The results of the trial - a combined phase 1 and 2 study - strongly support testing of the drug in a larger group of patients in both phase 2 and 3 trials, the authors say.

Is Failure To Reproduce Psychology Papers A Sign They Are Invalid?

Is Failure To Reproduce Psychology Papers A Sign They Are Invalid?

Following one of the largest-scale scientific reproducibility investigations to date, a group of psychology researchers has reported results from an effort to replicate 100 recently published psychology studies; though they were able to successfully repeat the original experiments in most all cases, they were able to reproduce the original results in less than half, they report.

Cannabis Use May Influence Brain Maturation In Young Males

Cannabis Use May Influence Brain Maturation In Young Males

Male teens who experiment with cannabis before age 16, and have a high genetic risk for schizophrenia, show a different brain development trajectory than low risk peers who use cannabis.
The discovery, made from a combined analysis of over 1,500 youth, contributes to a growing body of evidence implicating cannabis use in adolescence and schizophrenia later in life. 

Trash Or Treasure? Repurposing Wasted Food To Feed The Hungry

Trash Or Treasure? Repurposing Wasted Food To Feed The Hungry

"If I offered you a bruised banana, you probably wouldn't be interested," said Jonathan Deutsch, PhD, director of Drexel University's Center for Hospitality and Sport Management. "But what if I offered you some banana ice cream on a hot summer day? I bet you'd find that a lot more appealing."
It was this simple observation that inspired a new model for recovering would-be wasted - or surplus - food and repurposing it to feed hungry people, generate revenue and even create jobs. The model was recently piloted in West Philadelphia, home to a large population of low-income and food insecure individuals, as part of the Environmental Protection Agency's Food Recovery Challenge with support from Brown's Super Stores.

Genetic Ancestry Partially Explains A Racial Sleep Difference

Genetic Ancestry Partially Explains A Racial Sleep Difference

A new study clearly establishes a partial genetic basis underlying racial differences in slow-wave sleep, suggesting that it may be possible to develop sleep-related therapies that target specific genetic variants.
Using a panel of 1,698 ancestry informative genetic markers, the study found that greater African genetic ancestry was associated with lower amounts of slow-wave sleep in African-American adults. African ancestry explained 11 percent of the variation in slow-wave sleep after adjustment for potential confounders. Although a similar association was observed for delta power, no association with African ancestry was observed for sleep duration and efficiency.

Political Cohesion: Why Unmarried Women Voted For Obama And Married Women Voted For Romney

Political Cohesion: Why Unmarried Women Voted For Obama And Married Women Voted For Romney

Why do unmarried women tend to be more liberal and Democratic than their married counterparts? A key reason is because unmarried women -- those who have never been married and those who are divorced -- are more concerned about the status of women as a collective group according to survey results presented at the 110th Annual Meeting of the American Sociological Association. 

Is Smokeless Tobacco More Harmful Than Believed?

Is Smokeless Tobacco More Harmful Than Believed?

More than a quarter of a million people die each year that are linked to using smokeless tobacco, say scholars who believe that governments need to consider incorporating the regulation of smokeless tobacco into policy frameworks.
A paper funded by Leeds City Council and the Medical Research Council links smokeless tobacco to more than 62,000 deaths due to cancers of the mouth, pharynx and oesophagus and accounted for more than 200,00 deaths from heart disease in 2010.

Injectable Cryogel-based Whole-cell Cancer Vaccines

Injectable Cryogel-based Whole-cell Cancer Vaccines

New research could potentially yield a new platform for cancer vaccines. Leveraging a biologically inspired sponge-like gel called "cryogel" as an injectable biomaterial, the vaccine delivers patient-specific tumor cells together with immune-stimulating biomolecules to enhance the body's attack againstcancer. The approach, a so-called "injectable cryogel whole-cell cancer vaccine."
David Mooney, Ph.D., leads a Wyss Institute team developing a broad suite of novel cancer vaccines and immunotherapies.
