The Price Revolution in Europe, the runaway inflation that occurred during the years between 1515 to 1650, has been attributed to the sudden influx of silver from Mexico and Peru after discovery of the New World, which led to the decline in the value of of silver, and the growth of the European population and therefore competition for goods, which drove up prices.
There’s irony in having small bits of floatable plastic debris in the Pacific, even if the trash, although worrisome, doesn’t look like anything most of the public imagines
. Millions of years ago, many of the hydrogen and carbon atoms within these man-made polymers were part of marine life. Death, deposition and pressure simplified the organic molecules of the dead. Then a species that indirectly evolved from these oceanic ancestors accidentally stumbled upon a crude liquid.
Eventually they learned to use not only its energy content but its building blocks.
The yeast used to make beer has yielded what may be the first gene for beer foam, CFG1, scientists are reporting in a new study. The discovery opens the door to new possibilities for improving the frothy "head" so critical to the aroma and eye appeal of the world's favorite alcoholic beverage, beer. And it gives Science 2.0 another reason to write about beer.
We often associate awards with recent accomplishments, which is far from the case with Nobel Prizes. They're more akin to Hall of Fame inductions than batting titles. For some time they have been awarded for discoveries that are between one to five decades old. The committee tries to reward an achievement that has withstood the test of time, one that has created a key concept in the field and has opened up new avenues in research and science-related technologies.
When temperatures get low, close to absolute zero, some chemical reactions still occur at a much higher rate than classical chemistry says they should – in that extreme chill, quantum effects enter the picture. Researchers have now confirmed this experimentally, providing insight into processes in the intriguing quantum world in which particles act as waves and perhaps also explaining how chemical reactions occur in the vast frigid regions of interstellar space.
At both the macroscopic and micro levels, not all organisms get equal attention. Because of their sheer numbers, there are still undiscovered species of plants and roundworms at the feet of botanists and zoologists, respectively. Other specimens have been named but little is known about them. At the astronomical level we come across two factors: an overwhelming number of stars and bodies, compounded by a detection limit.

Computers are an indispensable part of laboratories. However, arrival of powerful mobile devices in the last few years and ever expanding ecosystem of scientific apps is all set to change that and usher in "there's an app for that" culture in laboratory workflows.
If a chemist has never been in a lab accident, he has been lucky. Of course luck is more likely to come to those whose mentors have learned from bad experiences and to those who have taken preventive measures seriously, despite their anal nature. Chemical reactions create products with behaviors that differ from those of the ingredients. That's what makes them intriguing, and it's also what makes them potentially dangerous. No matter how simple and controllable a reaction seems on paper, when it's carried out in real life, the exact conditions determine its rate. And when gases or acids acquire too much kinetic energy, no one wants eyes, lungs and flesh in their way.
If you, like me, are possessed with that gene that makes people eat the whole bag of chips (don't laugh - somewhere in that 100,000 words of ENCODE public relations blitzing
, I saw it), there is good news; not all of science is busy curing cancer and solving the big mysteries of the universe.
During London Olympics 2012, Google Knowledge Graph (Ref. 1
) proved to be very useful in knowing about various aspects of the games like player statistics, medal tally of countries, etc. Google Knowledge Graph is a gigantic network containing millions of objects and billions of facts and relationships, where objects are represented by nodes and relationships between the objects (nodes) are represented by edges (Figure 1).Figure 1 : Google Knowledge Graph
