Nanotube-soaked spiders spin super-strong silk
Orb spider silk, already among the toughest and strongest materials found in nature, could soon get a super-strong nanoscale upgrade. A research team from the University of Trento, Italy recently sprayed 15 Orb-weaving spiders, members of the Pholcidae family, with carbon nanotube or graphene particle solutions. They found that doing so caused some of the spiders to spin even stronger silk than what they normally do. The team administered five spiders with a graphene-water solution and another 10 with a carbon-water mix. While some spiders subsequently spun sub-par silk (and four of them died outright), a few of the carbon-dosed arachnids actually produced strands 3.5 times stronger than the most resilient natural silk we know about.
Researchers use cell-phone data, not precogs, to predict crime in London
Just this year we've seen open data give rise to recreations of Denmark in Minecraft, the ability to compare cities at the same scale and also collections of geo-mapped tweets and traffic lights. But what about a practical application for all of that info, one that has a more tangible benefit to society, like, say, crime prediction? That's what the University of Trento in Italy had in mind with its "Once Upon a Crime" study. The researchers coupled freely available (and anonymous, aggregated) demographic and mobile phone data with real crime data to forecast where in London an infraction might occur. Just how accurate was it? The Italian scientists say that their predictive algorithm was on-point, accurately anticipating whether an area would have either high or low levels of vice, 70 percent of the time. No, it's not quite enough to let Chief Anderton and co. start running wild just yet, but it could be a way to help cities struggling with budget woes decide what areas need more (or fewer) police patrols.
