Faced with an increased senior population and a dwindling working age one, government accountants have spread the word that elderly people need to be encouraged to work longer.
And they are being encouraged, by changes in pension policies that force them to do so. As a result, a social safety net that was designed to reduce retirement inequality nearly a century ago is once again increasing it - some groups are more likely to be disadvantaged by a rise in the state retirement age than others, because some people are more able to work as senior citizens than others.
If genes were lights on a string of DNA, the genome would appear as an endless flicker, as thousands of genes come on and off at any given time. Tim Hughes, a Professor at the University of Toronto's Donnelly Centre, is set on figuring out the rules behind this tightly orchestrated light-show, because when it fails, disease can occur.
Genes are switched on or off by proteins called transcription factors. These proteins bind to precise sites on the DNA that serve as guideposts, telling transcription factors that their target genes are nearby.
In their latest paper, published in Nature Biotechnology, Hughes and his team did the first systematic study of the largest group of human transcription factors, called C2H2-ZF.
The size of the human brain expanded dramatically during the course of evolution, imparting us with unique capabilities to use abstract language and do complex math. But how did the human brain get larger than that of our closest living relative, the chimpanzee, if almost all of our genes are the same?
(Inside Science) - Brain imaging can already pull bits of information from the minds of willing volunteers in laboratories. What happens when police or lawyers want to use it to pry a key fact from the mind of an unwilling person?

Summer sunshine makes most of us feel better, but there may be more to the benefits than just feeling good.
A growing body of evidence suggests sunlight itself – with adequate protection, of course – may actually be good for health.
Federal Communications Commission (FCC) chairman Tom Wheeler claims that his plan to regulate Internet Service Providers (ISPs) under Title II of the 1934 Telecommunications Act is “rooted in long-standing regulatory principles.”

Could our meat-loving Western diets push climate change over the edge?
That was the message of a recent report from UK think tank Chatham House that, even if the world moves away from fossil fuels, growth in meat and dairy consumption could still take global warming beyond the safe threshold of 2C.
The Black Death struck Europe in 1347, killing 30-50% of the European population in six violent years.
It wasn’t a one-off epidemic: it signaled the start of the second plague pandemic in Europe that lasted for hundreds of years and only slowly disappeared from the continent after the Great Plague of London in 1665-1666.
Titration is the process of determining the unknown concentration of a solution by adding a known amount of a solution with a known concentration.-->
Tumors require blood to emerge and spread. That is why scientists at The University of Texas MD Anderson Cancer Center believe that targeting blood vessel cells known as pericytes may offer a potential new therapeutic approach when combined with vascular growth factors responsible for cell death.
A study lead by Valerie LeBleu, Ph.D., assistant professor, Department of Cancer Biology at MD Anderson, looked at how cellular signaling by vascular growth factors called angiopoietin-2 (ANG2), when combined with depletion of pericytes, may decrease breast cancer tumor growth that spreads to the lungs. Targeting pericytes and ANG2 signaling may also offer new potential therapy options for treatment of some breast cancers.
The discovery, development and approval of new drug treatments has been stymied. Bureaucracy, coupled with a short patent window and attorneys waiting to pounce, has led to increased interest in vaccines, which require a separate litigation process than just filing a lawsuit and collecting a settlement, or obscure diseases guaranteed to have high payouts - the home run strategy.
And the when the public is not reading about how an FDA-approved drug hurt someone, or reading how drug companies are paying off doctors to get prescriptions, they want every new drug to be generic the moment it is developed. Small wonder small molecules are disappearing.
