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.

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.

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.

-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.

The research in inner-city London, published in BMJ Open, found these unsafe older drinkers are more likely to be of higher socioeconomic status.

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).
