Bitcoin calls itself the new money and says it can be minted and exchanged on the Internet, faster and cheaper than a bank.

It's gotten a lot of attention but how anonymous is it? Not very, if you have computers and about $1,500.

Several groups worldwide have shown that it is possible to find out which transactions belong together, even if the client uses different pseudonyms but it has only recently become clear that it is also possible to reveal the IP address behind each transaction. 

Results presented at the European Organisation for Research and Treatment of Cancer Symposium in Barcelona show "extremely promising" early phase 1 clinical trial results for the investigational drug AG-120 against the subset of patients with acute myeloid leukemia (AML) harboring mutations in the gene IDH1.

The finding builds on phase 1 results of a related drug, AG-221, against IDH2 mutations, presented at the most recent meeting of the American Association for Cancer Research. Results at this stage are preliminary, based on 17 patients.

The IDH1 mutation is found in 15-20 percent of all cases of AML, totaling about 3,500 cases of IDH1 AML per year.

Researchers using a new chemical process have converted the cellulose in sawdust into hydrocarbon chains, building blocks for gasoline.

 Cellulose is the main substance in plant matter and is present in all non-edible plant parts of wood, straw, grass, cotton and old paper.  These hydrocarbons can be used as an additive in gasoline or as a component in plastics. 

"At the molecular level, cellulose contains strong carbon chains. We sought to conserve these chains, but drop the oxygen bonded to them, which is undesirable in high-grade gasoline. Our researcher Beau Op de Beeck developed a new method to derive these hydrocarbon chains from cellulose," explains Professor Bert Sels. 

Epidemiologists have linked El Niño, a recurring pattern where every 2-7 years warm waters in the Equatorial Pacific change the weather, to short stature, also known as stunting,  which is usually due to chronic malnutrition.

The authors found that children born in coastal Peru during and after the 1997-98 El Niño, the last strong one, have a lower height-for-age than others born before the event. 

El Niño
has also been linked to epidemics of malaria, dengue fever, cholera and diarrhea, though the first recorded one was in 1525, so they have been happening a lot longer than that.. 

How can the weather stunt growth?

The computer-security firm Symantec says it may have found some of the most sophisticated malicious software ever made.

The cyber-espionage bug, called Regin, has been making attacks for many years without being caught.

Insects are the most diverse group of animals on earth. They inhabit nearly all terrestrial habitats. One of the factors underlying this success is the ability of insect eggs to survive in adverse conditions.

For a long time the ability to survive these adverse conditions has been attributed to maternal investment in the form of a protective eggshell. However, my research in the red flour beetle (Tribolium castaneum) shows that contrary to common belief, insect eggs are far from helpless.

Fairy tales have a tumultuous and fragile history. They originated as tales told by “folk”. They were passed down over generations to while away long winter nights, to provide entertainment at special occasions and for simple enjoyment.

Inevitably, as more people became literate and scholars began to record fairy tales, they were published. And then, with a wave of a magic wand, they entered the canon of European literature.

Honeybees pollinate a third of Australia's food crops. Losing them due to varroa might would cost the economy billions of dollars. David McClenaghan, Author provided

A nationwide outbreak of foot and mouth disease; an invasion of a devastating wheat disease; our honeybees completely wiped out. These are just three possible disastrous scenarios facing Australia; they’re considered in the Australia’s Biosecurity Future report published today by CSIRO and its partners.

Take a spot that only gets 6 to 8 inches of rain per year, with erosion causing such blinding dust that there is zero visibility, and build a wheat farm.

Wait, why would you do that? Washington State University researchers do it in the Horse Heaven Hills of south-central Washington to understand summer fallow management practices that can mean efficient water and soil conservation and help farmers everywhere.

There has been concern about a lessening of social engagement, mostly created by older people who see young people behaving differently than they did (and do). Last decade it was noted that young people were
less likely to join clubs, had fewer close friends, and were less likely to perceive others as trustworthy.

So young people don't join the Masonic Lodge in their college years. Does that mean they are less social? 

No, there has been an increase in extraversion and self-esteem, according to a paper in Personality and Social Psychology Bulletin. In a review, the authors examined past studies that utilized the Revised UCLA loneliness scale (R-UCLA) to analyze changes in loneliness over time, and gender differences in loneliness.
