New Scientist has written an article stating that new quantum technology can run a routine called Shor’s algorithm and that means the most dangerous threat posed by quantum computing, the ability to break the codes that protect our personal data, is now a step closer to reality.

Worse, they report this feat has been performed by not one but two research groups, acting independently; one led by Andrew White at the University of Queensland in Brisbane, Australia, and the other by Chao-Yang Lu of the University of Science and Technology of China, in Hefei. Both teams have built laser-based quantum computers that can implement Shor’s algorithm and defeat today’s most common encryption systems.

It’s already known that a person’s social environment can affect their health, with those who are socially isolated—that is, lonely suffering from higher mortality than people who are not. Now, in the first study of its kind, published in the current issue of the journal Genome Biology, UCLA researchers have identified a distinct pattern of gene expression in immune cells from people who experience chronically high levels of loneliness. The findings suggest that feelings of social isolation are linked to alterations in the activity of genes that drive inflammation, the first response of the immune system. The study provides a molecular framework for understanding why social factors are linked to an increased risk of heart disease, viral infections and cancer.

The way to a man’s heart is through his stomach but the way to a female chimpanzees may be through being a great thief. Researchers studying wild chimps in West Africa have learned that males steal desirable fruits from local orchards as a means of attracting female mates.

Lead researcher, Dr Kimberley Hockings from the University of Stirling’s Department of Psychology said: “We believe the males may be using crop-raids as a way to advertise their prowess to other group-members, especially the opposite sex.

Last month, University of Alaska Fairbanks researcher Katey Walter brought a National Public Radio crew to Alaska’s North Slope (actually, the NPR story is a lot better and has video, so you can probablly just go there and read it, but please come back when you are done - Editors ), hoping to show them examples of what happens when methane is released when permafrost thaws beneath lakes.

When they reached their destination, Walter and the crew found even more than they bargained for: a lake violently boiling with escaping methane.

The medical diagnosis of brain death is at odds with our traditional view of when death actually occurs, says Professor Allan Kellehear from the Centre for Death & Society at the University of Bath, speaking at an international conference on Death, dying & disposal.

A diagnosis of brain death uses factors like fixed and dilated pupils, lack of eye movement and absence of respiratory reflexes but the social understanding of death is that it occurs when the heart stops beating.

This makes decisions that often follow brain death, such as organ removal and the cessation of life support, potentially unsettling for the bereaved.

A way to convert natural gas into raw materials for the chemical industry and generate power as a by-product could lead to more environmental benign manufacturing processes.

Making synthesis gas - a blend of hydrogen and carbon monoxide - is a key step in turning natural gas or biomass into bulk chemicals, such as acetic acid, methanol, oxygenated alcohols, isocyanates, and ammonia, which are the feedstock of the global chemical industry. Synthesis gas can also be converted into synthetic diesel fuel. In the conventional process of synthesis gas production, a catalyst and heat are required, which itself requires energy.

A primary mystery puzzling neuroscientists -- where in the brain lies intelligence" -- just may have a unified answer.

In a review of 37 imaging studies related to intelligence, including their own, Richard Haier of the University of California, Irvine and Rex Jung of the University of New Mexico have uncovered evidence of a distinct neurobiology of human intelligence.

Research here shows that an obscure form of RNA, part of the protein-making machinery in all cells, might play an important role in human cancer. These ultraconserved non-coding RNAs (UCRs) have been considered “junk” by some researchers, but a new report in the September issue of the journal Cancer Cell indicates that this may not be the case.

The study found that UCRs, like classic oncogenes, can contribute to cancer development. It also showed that the type and amount of UCRs is different in cancer cells for each of three cancer types, suggesting that these molecules might prove useful in diagnosing the disease and in determining a patient’s prognosis and perhaps even treatment.

The fossil record seems to indicate that the diversity of marine creatures increased and decreased over hundreds of millions of years in step with predator-prey encounters, Virginia Tech geoscientists report in the Proceedings of the National Academy of Science.

For decades, there has been a debate between paleontologists, biologists, and ecologists on the role of ecological interactions, such as predation, in the long term patterns of animal evolution.
