The latest bomber to make its debut over Iraq has four engines, no cockpit, and a flight time limited by the length of its battery. ISIS, the radical insurgent group holding territory in both Syria and Iraq, is fighting for its life in Mosul, the large city in Northern Iraq it has held since 2014. Most of the weapons ISIS uses are are familiar, if still horrific: rifles and mortars, artillery and suicidal car bombs. To that arsenal, ISIS recently added commercial drones, converted into tiny bombers.
Delivering objects via drone is a tempting notion bound by hard constraints: drones are small, so the cargo has to be small. Drones need power to fly, and any additional weight requires more power to cover the same distance, which further limits the size of the cargo. For a drone delivery to make sense, then, the small cargo has to justify both its weight and the urgency of a drone flight. Pound for pound and ounce for ounce, few cargoes match that limitation better than blood.
Walking on two legs is one of the hardest ways to travel. Few creatures do it in nature, and when humans have made walking robots, the two-legged ones tend to fall down a lot. What if, instead of carefully calibrated bodies, a walking robot was simply built around a torso that defied gravity?
Speech recognition software isn't perfect, but it is a little closer to human this week, as a Microsoft Artificial Intelligence and Research team reached a major milestone in speech-to-text development: The system reached a historically low word error rate of 5.9 percent, equal to the accuracy of a professional (human) transcriptionist. The system can discern words as clearly and accurately as two people having a conversation might understand one another.
