Does only spending what you make lead to suicide? In the world of weak observational studies, it can. Suicides in Greece reached a 30 year all-time high in 2012, with a sustained upward trend starting in June 2011, the month that the government introduced austerity measures to get loans and help pay down the country's debts, currently at 175 percent of GDP and caused by overspending on social services. 

15 years ago, the name "Aidan" was barely a blip on the radar of Americans with new babies, ranking a lowly 324th on the Social Security Administration's list of popular baby names.

Then a popular character with that name was on the television show "Sex and the City" and though fathers dreaded that their child was going to have the same name as some other child of a mother who watched the show, it happened all across America anyway. Since then, that name has been in the top 20.

A brilliant-green sea slug can live for months at a time "feeding" on sunlight like a plant and now scientists have the first direct evidence that its chromosomes have some genes that come from the algae it eats. 

Those genes help sustain photosynthetic processes inside the slug that provide it with all the food it needs. 

Importantly, this is one of the only known examples of functional gene transfer from one multicellular species to another, which is the goal of gene therapy to correct genetically based diseases in humans.

An insulin-regulating hormone that had only been postulated to exist has been discovered.

The hormone, called limostatin after the Greek goddess of starvation, Limos, tamps down circulating insulin levels during recovery from fasting or starvation. In this way, it ensures that precious nutrients remain in the blood long enough to rebuild starving tissues, rather than being rapidly squirreled away into less-accessible fat cells.

The researchers first discovered limostatin in fruit flies but then quickly identified a protein with a similar function in humans.

The rate of global warming that had been predicted in the 1990s did not come to pass. In the 21st century, warming has been significantly slower than all the models had predicted, leading to claims that the models contained systematic errors.

Not so, according to a new analysis, it is just random variation. Jochem Marotzke, Director at the Max Planck Institute for Meteorology in Hamburg, and Piers M. Forster, a professor at the University of Leeds in the UK, did a statistical analysis and found that the models do not generally overestimate man-made climate change and so global warming is still highly likely to reach critical proportions by the end of the century if CO2 emissions are not reduced. 

Inhibiting the action of a particular enzyme called polymerase theta, or PolQ, dramatically slows the growth of tumor cells tied to BRCA1 and BRCA2 genetic mutations which, in turn, are closely tied to breast and ovarian cancers, according to a new paper.
