Michael Ross writes "Of all the open source content management systems used for building websites, Drupal has a reputation for being one of the most flexible and powerful available, but not the easiest for web designers to use. Drupal version 7 has made some strides in alleviating those flaws, but there is still much progress to be made. During the past few years, a number of books have been published that explain how Drupal designers can do custom theming, but they tend to focus on the technical details of the theme layer, and not the practice of web design when using Drupal as a foundation. That rich yet neglected subject area is the focus of a new book, Drupal for Designers: The Context You Need Without the Jargon You Don't." Keep reading to see what Michael has to say about the book.

An anonymous reader writes "Malaysia's new internet law maybe simply the toughest on the planet. According to the new law which was amended because of protesters the originators of content are those who own, administer, and/or edit websites, blogs, and online forums. This means that a blogger or forum moderator who allows nasty comments against the government on their site can be held liable. An internet café manager is accountable if one of his or her customers sends illegal content online through the store's WiFi. A mobile phone user is the perpetrator if defamatory content is traced back to his or her electronic device. Critics of the new law contend also that a person is considered guilty until proven innocent."

An anonymous reader writes "For reasons that scientists have not conclusively determined, women are happier than men. And now, researchers think that they may have pinpointed one of the reasons for that. They have found a gene in women that predicts the level of happiness in women. 'After controlling for various factors, ranging from age and education to income, the researchers found that women with the low-expression type of MAOA were significantly happier than others. Compared to women with no copies of the low-expression version of the MAOA gene, women with one copy scored higher on the happiness scale and those with two copies increased their score even more. While a substantial number of men carried a copy of the "happy" version of the MAOA gene, they reported no more happiness than those without it.'"

derekmead writes "Hot on the heels of the U.S. Air Force's most recent failed test of an unmanned hypersonic vehicle, Russia now says it wants to jump into the hypersonic game with a long-range bomber. Will Russia's newest Bear fly at 4,500 miles an hour? The Russian military sure hopes so. 'I think we need to go down the route of hypersonic technology and we are moving in that direction and are not falling behind the Americans,' Russian Deputy Prime Minister Dmitry Rogozin said on Russian television. 'The question is will we copy the Americans' 40-year experience and create a [Northrop] B-2 analog or will we go down a new, ultramodern technology route, looking to the horizon, and create a machine able to penetrate air defenses and carry out a strike on any aggressor.' The Russians want their plane operational by 2020, which doesn't seem particularly realistic — we are talking about five times the speed of sound here, and Russia is just starting engine development. The U.S., meanwhile, has been investing in its Waverider program since 2004, and the last test of the X-51A scramjet-powered missile failed after just 15 seconds."

scibri writes about robots helping neuroscientists dig into the brains of (animal) test subjects. From the article: "Robots designed to perform whole-cell patch-clamping, a difficult but powerful method that allows neuroscientists to access neurons' internal electrical workings, could make the tricky technique commonplace. Scientists from MIT have designed a robot that can record electrical currents in up to 4 neurons in the brains of anesthetized mice (abstract) at once, and they hope to extend it to up to 100 at a time. The robot finds its target on the basis of characteristic changes in the electrical environment near neurons. Then, the device nicks the cell's membrane and seals itself around the tiny hole to access the neuron's contents."

redletterdave writes with news of a drone that's helping weather forecasters this hurricane season. From the article: "Hurricane prediction is not always an exact science — back in 2005, Hurricane Rita was projected to hit Houston, but missed the region entirely — but the NOAA (National Oceanographic and Atmospheric Administration) is already on the case. A few weeks ago today, the agency launched an experimental Wave Glider robot named Alex into the ocean, hoping the unmanned drone can forecast the direction of future storms. The Wave Glider, which is completely powered by the waves and the sun thanks to solar panels and a unique thrust engine, contains a GPS unit, satellite communications systems, and sensors for measuring water temperature, wind speed, and various wave characteristics. With its ability to withstand strong winds and thrashing waters — which are typically prohibitive for humans and even aerial vehicles — and its ability to theoretically drift in the ocean endlessly without refueling, a single Wave Glider could be used to monitor not just one storm, but several hurricanes occurring over an entire seasonal period. The NOAA hopes to soon use more Wave Glider robots like Alex to help determine more accurate hurricane watches and warnings."

DevotedSkeptic writes "Kepler has continued its stellar (pun intended) discovery spree, this time locating multiple planets orbiting a binary star system. This is especially interesting because it proves that more than one planet can form under the stresses of a binary star system. The system is known as a circumbinary planetary system, a mechanism where a planet orbits two stars. Prior to this discovery, having multiple planets in a circumbinary system was unproven. Named Kepler-47, the system consists of a pair of orbiting stars that eclipse each other every 7.5 days. One star is similar in size to our Sol, however it only provides approximately 84% of Sol's light, the other is smaller, measuring one third of the size of Sol and emits less than 1% of Sol's light. Kepler-47b is the closer planet to its two suns, orbiting in 50 Earth days. Kepler-47c is further out and orbits every 303 days, within the Goldilocks zone. 'Unlike our sun, many stars are part of multiple-star systems where two or more stars orbit one another. The question always has been — do they have planets and planetary systems? This Kepler discovery proves that they do,' said William Borucki, Kepler mission principal investigator at NASA's Ames Research Center in Moffett Field, Calif. 'In our search for habitable planets, we have found more opportunities for life to exist.'"

Taco Cowboy writes "The recent lost by Samsung in a court battle against Apple apparently does not put a dent to other parties determination to fight Apple, inside and outside of the court system HTC's Chairperson, Ms. Cher Wang, has publicly re-iterated her belief that the $1 billion jury verdict against Samsung in the U.S. 'does not mean the failure of the entire Google Android ecosystem.'"
