Does E always equal mc²? University of Arizona physicist Andrei Lebed suspects not – and plans to try and check. Einstein’s famous equation describes the fact that energy and mass are essentially the same thing and can be converted into one other. It’s since been validated in countless experiments and calculations – indeed, many technologies…
From Slate’s Bad Astronomy blog: Global warming is real. Temperatures are changing, climate is changing, and most importantly, arctic ice is changing, melting. It is absolutely critical we understand this process better so that we can better understand the implications, and some of the most formidable tools in our possession are Earth-observing satellites. Their keen…
Most cultural institutions and research laboratories still rely on magnetic tape to archive their collections. Hitachi recently announced that it has developed a medium that can outlast not only this old-school format but also CDs, DVDs, hard drives and MP3s. The electronics giant partnered with Kyoto University’s Kiyotaka Miura to develop “semiperpetual” slivers of quartz…
The Large Hadron Collider will operate for two more months then shut down through 2014, allowing engineers to lay thousands more superconducting cables aimed at bringing the machine up to “full design energy.” This will vastly improve its capacity to simulate the moments after the Big Bang nearly 14 billion years ago.
SciDev.Net brings you the most commented on articles in 2012, including news, editorials and opinions, spanning topics as diverse as wind energy, access to weather data and communicating science.
It seems that an increasing number of scientific studies are just plain wrong and are ultimately retracted. Worse, a study published in October 2012 in the Proceedings of the National Academy of Sciences (uh, if it’s true) claims that the majority of retractions are due to some type of misconduct, and not honest mistakes, as long assumed….
At the end of every December, ScienceNOW takes a look back at some of its favorite stories of the year. These aren’t necessarily the biggest scientific advances (see our Breakthrough of the Year). They’re simply the funniest, wackiest, and most popular items they’ve run. Enjoy.
The first truly Earth-like alien planet is likely to be spotted next year, an epic discovery that would cause humanity to reassess its place in the universe. While astronomers have found a number of exoplanets over the last few years that share one or two key traits with our own world — such as size…
You’ve heard the hype a hundred times: Physicists hope to someday build a whiz-bang quantum computer that can solve problems that would overwhelm an ordinary computer. Now, four separate teams have taken a step toward achieving such “quantum speed-up” by demonstrating a simpler, more limited form of quantum computing that, if it can be improved,…
The whole point of an explanation is to reduce something you don’t know to something you do. By that standard, you don’t gain much by explaining anything in terms of black holes. Appealing to the most mysterious objects known to science as an explanation sounds like using one mystery to explain another. Yet this is…
