Neural Networks-Equipped Robots Evolve the Ability To Deceive 116

Posted by timothy from the I-never-blinked-that dept.
pdragon04 writes "Researchers at the Ecole Polytechnique Fédérale de Lausanne in Switzerland have found that robots equipped with artificial neural networks and programmed to find 'food' eventually learned to conceal their visual signals from other robots to keep the food for themselves. The results are detailed in a PNAS study published today."

Is Typing Ruining Your Ability To Spell? 494

Posted by Soulskill from the my-spellchecker-sure-thinks-so dept.
NSN A392-99-964-5927 writes "My handwriting abilities have deteriorated over the years. Putting a real pen to paper, I get frustrated over how to spell correctly, as I am so accustomed to using a keyboard and knowing where the letters are. Having spoken to a few friends, I've found that this has become apparent to them, too. I've noticed that my grammar is also affected; maybe this is because I spent too much time on IRC and lowered my standards. Hand-written words are now becoming obsolete. There is often no need to think about writing anymore, or about how something is spelled. Are other Slashdotters having the same problem? (I'm used to Telex machines, which should give you an indication of how old I am.)"

The Homemade Hard Disk Destroyer 497

Posted by CmdrTaco from the if-you-can-recover-that-you-earned-it dept.
Barence writes "All businesses have sensitive data they need to destroy when they replace PCs, but disposing of hard disks properly can be an expensive business. This has led one IT manager in the UK to come up with his own, homemade solution — Bustadrive. It uses a powerful 'hydraulic punch' to physically deform a hard disk, rendering it virtually unreadable, and requires nothing more than a pull of the lever on the front — similar to a drinks-can crusher. PC Pro tested the Bustadrive, and also sought the opinions of data destruction companies as to whether the device was really as effective as hoped, or just a fun way to mangle a hard disk or two."

A Mathematical Model For a Spreading Zombie Infestation 121

Posted by Soulskill from the integrating-by-parts dept.
cloude-pottier writes "What do you do when zombies attack? Turn to a mathematician to come up with a model for the spread of a zombie infestation, of course! Students at Carleton University and the University of Ottawa have published a paper in a book titled Infectious Disease Modelling Research Progress detailing how to model the spread of a zombie population and various complications in managing the spread of the infestation. They even give humans a fighting chance in some cases! The original paper (PDF) can be found at their professor's website."

Yahoo Revives Pay-Per-Email, With Charitable Twist 287

Posted by timothy from the penny-post-sans-post dept.
holy_calamity writes "Yahoo research have started a private beta of a scheme that resurrects the idea of charging people to send email to cut spam. Centmail users pay $0.01 for each message they send, with the money going to a charity of their choice. The hope is that the feel good effect of donating to charity will reduce the perceived cost of paying for mail and encourage mass adoption, making it possible for mail filters to build in recognition of Centmail stamps."

Gardeners Told to Give Exhausted Bees an Energy Drink Screenshot-sm 200

Posted by samzenpus from the it's-what-bees-crave dept.
In an effort to help Britain's declining bee population, the Royal Society for the Protection of Birds is urging gardeners to leave out a homemade energy drink for tired bees. The RSPB says that a mix of two tablespoons of sugar with a tablespoon of water makes a perfect bee-boosting drink. Val Osborne, head of wildlife inquiries at the RSPB, said, "Many people keep seeing bees on the ground and assume they are dead, but chances are they are having a rest. Much like us, a sugary drink could boost their energy levels and a simple sugar and water combination will be a welcome treat."
