The diagram below shows five concentric circles constructed in such a way that the area of each annulus is equal to that of the central circle. Within the first annulus, a square has been constructed…

The number of conferences held every year around the world to present and discuss topics in frontier particle physics is surprisingly large: over a hundred per year. Just look at the following list…

In October 1908, after several false starts, one of the world's most effective predators finally found a niche where its population could begin to boom.  A century later, this ruthless hunter…

The earth has abundant energy sources, if only we would bother to tap them. Wind power has had its financial and ethical ups and downs, with wind farms using gargantuan, expensive wind towers…

Most people drink alcoholic beverages without actually knowing what happens to it as it enters into their body. "A hangover" is a common thing alcohol drinkers know, or maybe they have heard that…

And so here it is, the first public Landsat 8 image. The geographical honours goes to Wyoming and Colorado and the area where the Great Plains meets the Rocky Mountains in USA. I wrote about the…

From the perspective of one theoretical particle physicist Planck found far from "nothing". The ESA's Planck probe largely corroborates the findings of NASA's WMAP probe, but it leaves theoretical…

Over 200 million years ago, a mass extinction wiped out an estimated 76 percent of marine and terrestrial species. It marked the end of the Triassic period and the onset of the Jurassic, clearing the…

An innovative new process releases the energy in coal without burning, while capturing carbon dioxide, the major greenhouse gas that is the target of emissions reduction goals. How close is it to…

On Wednesday, March 19th, a group of researchers organized by the Society for Neuroscience descended on Capitol Hill to let Congress know how important it was to reverse the budget cuts inflicted by…

Consumption of extra virgin olive oil has been linked to reduced risk of Alzheimer's disease (AD) and its benefit may lie in one component of olive oil that helps shuttle the abnormal AD proteins out…

A team of scientists has uncovered how some sea snakes have developed 'shrunken heads' - literally smaller physical features than their related species. A large head would seem to be a welcome trait…

Hunting in Africa has halved the number of primates, according to estimates, but that is not the extend of the problem. Primates help with dispersal of seed and the reduction in primates has led to a…

In my previous blog post, Introduction to the 555 Timer IC , you learned how to build an optical Theremin using a 555 Timer. The original Theremin used radio frequency interference caused by the…

Thanks to a supersensitive space telescope and some sophisticated supercomputing, scientists from the international Planck collaboration have made the closest reading yet of the most ancient story in…

The mission of the ESA Planck satellite is to observe the Universe of the past, seeing back in time, right after the Big Bang. The image that the Planck scientists revealed today is that of the…

England’s Prince Charles famously said, “(GMOs) are not in God’s plan.” If you don't have a direct line to God like he does, that's okay, you can still easily see that most resistance to GMOs is…

Mandates and subsidies have created an artificial green energy industry. In the case of ethanol, that has led to escalating corn prices. Higher prices have encouraged some farmers to switch to…

The handling of "incidental findings" in clinical genome and exome sequencing has been addressed by the American College of Medical Genetics and Genomics (ACMG).  Incidental findings are health…
