Virtual money: User's identity can be revealed much easier than thought
Bitcoin is the new money: minted and exchanged on the Internet. Faster and cheaper than a bank, the service is attracting attention from all over the world. But a big question remains: are the transactions really anonymous? Researchers at the University of Luxembourg have now demonstrated how the IP address behind each transaction can be revealed with only a few computers and about €1500.

Few operations for epilepsy despite their safety and efficacy
A study at Sahlgrenska Academy, University of Gothenburg, has found that epilepsy surgery is a safe, effective and low-risk procedure. Nevertheless, few Swedes have the operation, and those who are interested may have to wait a long time for presurgical counseling.

Why fruit flies could lead to better beer (video)
Your beer may attract annoying fruit flies, but listen up before you give them a swat. Researchers found the yeast cells in beer are producing odor compounds -- acetate esters -- that lure flies and that could lead to the best beer you haven't even tasted yet. This week's Speaking of Chemistry explains why. Check it out at http://youtu.be/HQNlGuZvCvA.

Feeling -- not being -- wealthy drives opposition to wealth redistribution
People's views on income inequality and wealth distribution may have little to do with how much money they have in the bank and a lot to do with how wealthy they feel in comparison to their friends and neighbors, according to new findings published in Psychological Science, a journal of the Association for Psychological Science.

Study maps how city neighborhoods affect diabetes risk
Ground zero for identifying ways to stop the rise in diabetes prevalence is Philadelphia, which has the highest diabetes rate among the nation's largest cities. Public health researchers at Drexel University looked at how neighborhood and community-level factors -- not just individual factors like diet, exercise and education -- influence people's risk. Their new study adds insight into the role of the physical and social environment on diabetes risk, zip code by zip code throughout the city.

NIH scientists determine how environment contributes to several human diseases
Using a new imaging technique, National Institutes of Health researchers have found that the biological machinery that builds DNA can insert molecules into the DNA strand that are damaged as a result of environmental exposures. These damaged molecules trigger cell death that produces some human diseases, according to the researchers. The work, appearing online Nov. 17 in the journal Nature, provides a possible explanation for how one type of DNA damage may lead to cancer, diabetes, hypertension, cardiovascular and lung disease, and Alzheimer's disease.

Body size requires hormones under control
In a study now published in the scientific journal eLife, a research group from Instituto Gulbenkian de Ciência, led by Christen Mirth, shed new light on how animals regulate body size. The researchers showed that the timing of synthesis of a steroid hormone called ecdysone is sensitive to nutrition in the fruit fly and described the key proteins involved in this regulatory mechanism. This study explains what causes hormones to become environmentally-sensitive.

Problem gambling, personality disorders often go hand in hand
The treatment of people who cannot keep their gambling habits in check is often complicated because they also tend to suffer from personality disorders. So says Meredith Brown of Monash University in Australia, in a review in Springer's Journal of Gambling Studies.

Researchers find way to turn sawdust into gasoline
Researchers at KU Leuven's Centre for Surface Chemistry and Catalysis have successfully converted sawdust into building blocks for gasoline. Using a new chemical process, they were able to convert the cellulose in sawdust into hydrocarbon chains. These hydrocarbons can be used as an additive in gasoline, or as a component in plastics. The researchers reported their findings in the journal Energy & Environmental Science.

Study supports free 'super Wi-Fi'
The need for the wireless transfer of data will increase significantly in the coming years. Scientists at the Karlsruhe Institute of Technology therefore propose to turn some of the TV frequencies that will become free into common property and to use it to extend existing wireless networks instead of using the frequencies for mobile communications. Their study, published in the international journal Telecommunications Policy, recommends that the additional frequencies not be marketed but made available to the population and companies at no cost.

Policing Canada in the 21st century: New policing for new challenges
A new expert panel report, Policing Canada in the 21st Century: New Policing for New Challenges, released today by the Council of Canadian Academies, details the complexity and global nature of policing in the modern age. Overall, a 12-member Expert Panel determined that safety and security cannot just rest with Canada's policing services. Specialists, public and private security services, and other first responders all have a vital role to play in an interconnected safety and security web.

Blu-ray disc can be used to improve solar cell performance
Who knew about Blu-ray discs? One of the best ways to store high-definition movies and television shows because of their high-density data storage, Blu-ray discs also improve the performance of solar cells, according to a new Northwestern University study. Researchers have discovered that the pattern of information written on a Blu-ray disc -- and it doesn't matter if it's Jackie Chan's 'Supercop' or the cartoon 'Family Guy' -- works very well for improving light absorption across the solar spectrum.

Blind scottish centipede unlocks clues to the origins of creepy crawlies
The arthropods are one of Earth's real success stories, with more species of arthropod than in any other animal phylum, but our knowledge of arthropod genomes has been heavily skewed towards the insects. In a report publishing Nov. 25 in the open-access journal PLOS Biology, the team of scientists (over 100 from 15 countries) reveals our first glimpse of a myriapod genome and uses it to explore the genetic basis of centipede biology and of the incredible diversification of arthropods.

Study examines FDA influence on design of pivotal drug studies
An examination of the potential interaction between pharmaceutical companies and the US Food and Drug Administration (FDA) to discuss future studies finds that one-quarter of recent new drug approvals occurred without any meeting, and when such meetings occurred, pharmaceutical companies did not comply with one-quarter of the recommendations made by the FDA regarding study design or primary outcome, according to a study in the Nov. 26 issue of JAMA.

Why cancer cells grow despite a lack of oxygen
Healthy cells reduce their growth when there is a lack of oxygen (hypoxia). This makes it even more surprising that hypoxia is a characteristic feature of malignant tumors. In two publications in the current edition of the 'Nature Communications' journal, researchers from Goethe University and the Justus-Liebig-University of Giessen report on how cancer cells succeed at circumventing the genetic program of growth inhibition.
