It's time to allow sex selection in IVF

As part of a periodic review, the National Health and Medical Research Council (NHMRC) is calling for public submissions on its draft guidelines on the use of assisted reproductive technology in clinical practice and research. This, in lay terms, is the practice of in vitro fertiliszation (IVF).

'Magic' sphere for computing using photons

'Magic' sphere for computing using photons

In several years - in perhaps decades, or maybe never - our computers, nanoantennas and other kinds of equipment could operate on the base of photons, rather than electrons. Even now we are practically prepared to accomplish this switch. If it happens, the spheres studied by an international group of Russian, French and Spanish scientists will definitely be able to become one of the elementary components of new photonic devices.

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.

Young adults know e-cigarettes are not tobacco, academics are more confused

Many college students are making their way back to campus this month, and back to the habits -- good or bad -- that dorm-life promotes. A new study finds that young adults under 25, including high school grads and college students, are more likely to rate hookah and e-cigarettes as safer than cigarettes, when compared to 25 to 34-year-olds, according to a paper in Health Education & Behavior.

Anti-aging tricks from alpha lipoic acid dietary supplement seen in mice

In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are both a sign of aging and contribute to it. Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis.

The discovery highlights a potential avenue for the treatment for chronic diseases.

The results were published Thursday, August 20 in Cell Reports.

Female soldiers at no greater risk for PTSD in new study cohort

While past research on the question has found otherwise, a new study by Defense and Veterans Affairs researchers suggests that women in the military are at no greater risk than men for developing posttraumatic stress disorder, given similar experiences--including combat.

Something to chew on: Is smokeless tobacco more harmful than believed?

More than a quarter of a million people die each year from using smokeless tobacco, say scholars from the University of York, University of Edinburgh and Imperial College, London. Millions more have their lives shortened by ill health due to the effects of chewing tobacco-based products, they say, stating they are the first to assess the global impact of smokeless tobacco consumption on adults.

The team says governments and public health bodies need to consider incorporating the regulation of smokeless tobacco into policy frameworks.

With the EPA over-regulating affordable energy, we need basic energy rights for low-income populations

-Low-income populations deserve basic energy rights to protect them from "energy insecurity" and the environmental and related health risks from living in "energy sacrifice zones" where energy is produced. The disproportionate burden these vulnerable communities bear across the continuum of energy supply and demand is discussed in Environmental Justice.

20 percent of senior citizens drink way too much alcohol

One in five older people who drink alcohol are consuming it at unsafe levels - over 21 units of alcohol for men and 14 units for women each week - according to a study by King's College London. The research in inner-city London, published in BMJ Open, found these unsafe older drinkers are more likely to be of higher socioeconomic status.

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, suggests a new study that will be presented at the 110th Annual Meeting of the American Sociological Association (ASA).
