  • Dutch trains get lasers to zap track debris

    You might not see leaves as hazards, but train operators would beg to differ -- foliage on the tracks not only makes it harder for trains to stop, but also messes with anti-collision signals. The greenery might not be much of a danger for much longer, however. Dutch Railways is testing a laser system that zaps leaves (and other organic material) before it reaches the wheels, keeping the tracks clean. You can already use water jets and sand gels to do this, but they have limited supplies and sometimes damage the rails. The lasers run so long as the train has power, and they actually help the metal by drying it and preventing leaves from sticking.

  • Longtime Castlevania producer Koji Igarashi leaves Konami

    Koji Igarashi, longtime producer of the Castlevania series, announced his departure from Konami over the weekend. Igarashi's last day at the publisher was March 15, and marked the end of a career at Konami that spanned over 20 years. "I've decided to break out on my own to have the freedom to make the kind of games I really want to make - the same kind I think fans of my past games want as well," Igarashi said in a statement to Polygon. The man affectionately called "IGA" by fans began his time with the dark action-adventure series as assistant director of Castlevania: Symphony of the Night on PlayStation. His involvement in the series has since dwindled, as developer Mercury Steam took it over with 2010's Castlevania: Lords of Shadow. "Leaving Konami was a big decision, and not one I took lightly - I've spent my entire career there, made many friends, and had a lot of great opportunities - but I hope all the gamers and fans who have supported me in the past will join me in being excited about what comes next. Wish me luck," he added. Igarashi will present "There and Back Again: Koji Igarashi's Metroidvania Tale" at the Game Developers Conference this week in San Francisco, tracing the "experiences and methodology" of the series over the last 15 years.

  • MIT professor touts first 'practical' artificial leaf, signs deal with Tata to show up real plants

    A professor at MIT claims to have Mother Nature beat at her own game. Dr. Daniel Nocera says his invention is ten times more efficient at photosynthesis than a real-life leaf, and could help to bring affordable alternative energy to developing countries. Described as an "advanced solar cell the size of a poker card," the device is made of silicon, electronics, and inexpensive catalysts made of nickel and cobalt. When placed in a gallon of water under direct sunlight, the catalysts break the H2O down into hydrogen and oxygen gases, which are then stored in a fuel cell -- the energy produced is apparently enough to power a single house for a day. Of course, this isn't the first time we've seen scientists try to one-up nature, in fact, we've seen solar-powered leaves before, but this thing actually looks poised for the mass market -- Nocera signed a deal with Tata in October. Full PR after the break.

  • Anand Chandrasekher resigns from Intel after 24 years, leaves scandal mongers hanging

    Well, as tech industry resignations go, this one's not exactly sensational, but Anand Chandrasekher's plan to leave Intel is no doubt a popular topic of conversation with chip makers this week. The chief of the company's Ultra Mobility Group (UMG) and the man behind Atom, apparently resigned "to pursue other interests." Intel Architecture Group's Mike Bell and Dave Whalen will co-manage UMG in Chandrasekher's stead -- and that's about it for sordid details. His resignation isn't apt to be marked by a Mark Hurd-style scandal, and we have a feeling this is a pretty straight forward changing of the guards, but, then again, we said the same thing when Dirk Meyer left AMD.

  • Glass leaves sweat to generate electricity, get nervous in public situations

    Researchers at the University of California, Berkeley, the University of Michigan and MIT have created glass "leaves" with networks of veiny channels filled with water. The smallest channels extend all the way to the edges of the leaf, where open ends allow water to evaporate, which draws water along the central stem of the leaf -- at a rate of about 1.5 centimeters per second. The glass leaves have been wired for electricity by adding metal plates to the walls of the central stems and connecting them to a circuit. Researchers then charge the plates and the water inside the stems creates two conducting layers separated by an insulating layer, which acts as a capacitor. The waterflow is then periodically interrupted with air bubbles, and every time a bubble passes through the plates a small electrical current is generated -- about 2 - 5 microvolts per bubble. The team thinks that on a large scale, artificial trees could be use to generate large amounts of energy entirely through evaporation.

  • John Garcia abruptly resigns as head of Sprint's CDMA business

    Look, we needn't tell you that things aren't exactly kosher for Sprint right now. SK Telecom just said "thanks, but no thanks" to a potential relationship, it managed to post a net loss of $326 million in Q3 and it's staring down the barrel of a $1.2 billion class-action ETF suit. All that considered, the sudden and apparently unplanned departure of the carrier's head of CDMA isn't apt to help things. John Garcia, without any (public) rhyme or reason, has decided it best to not clock in on Monday, and at the moment of his leaving, the company had no comment on the situation. Bigwig Keith Cowan has been chosen as the interim replacement while it searches for a successor, and in related news, Bill Morgan (SVP of brand management) will begin reporting directly to CEO Dan Hesse.[Via mocoNews]
