The Story of My As-Yet-Unverified Impact Crater 250

Posted by Soulskill from the dent-in-the-world dept.
tetrahedrassface writes "When I was very young, my dad took me on a trip to his parents' farm. He wanted to show me 'The Crater.' We walked a long way through second generation hardwoods and finally stood on the rim of a hole that has no equal in this area. As I grew up, I became more interested in The Crater, and would always tell friends about it. It is roughly 1,200 feet across and 120 feet deep, and has a strange vibe about it. When you walk up to it, you feel like something really big happened here. Either the mother of all caves is down there, or a large object smashed into this place a long, long time ago. I bought aerial photos when I was twelve and later sent images from GIS to a geologist at a local university. He pretty much laughed me out of his office, saying that it was a sinkhole. He did wish me luck, however. It may be sinkhole. Who knows? Last week I borrowed a metal detector and went poking around, and have found the strangest shrapnel pieces I have ever seen. They are composed of a metal that reacts strongly to acids. The largest piece so far reacted with tap water and dish-washing detergent. My second trip today yielded lots of strange new pieces of metal, and hopefully, one day the truth will be known. Backyard science is so much fun. And who knows; if it is indeed a cave, maybe Cerberus resides there."

Firesheep Countermeasure Tool BlackSheep 122

Posted by CmdrTaco from the baa-ram-yew dept.
Orome1 writes "Slashdot already covered Firesheep, the Firefox extension that makes it easier to steal logins and take over social media and email accounts after users log in from a WiFi hotspot or even their own unprotected network. Zscaler researchers have created, and are now offering to every consumer, a free Firefox plugin called BlackSheep, which serves as a counter-measure. BlackSheep combats Firesheep by monitoring traffic and then alerting users if Firesheep is being used on the network. BlackSheep does this by dropping 'fake' session ID information on the wire and then monitors traffic to see if it has been hijacked."

You do realize that such devices are only a marginal part of our energy consumption? Transport and Heating/Cooling are the biggest energy consumers today. All the rest is peanuts.

Remember, if everyone saves a bit of energy, humankind as a whole also only saves a bit of energy.

Oil Leak Could Be Stopped With a Nuke 799

Posted by samzenpus from the lesser-of-two-disasters dept.
An anonymous reader writes "The oil leak in the Gulf of Mexico could be stopped with an underground nuclear blast, a Russian newspaper reports. Komsomoloskaya Pravda, the best-selling Russian daily, reports that in Soviet times such leaks were plugged with controlled nuclear blasts underground. The idea is simple, KP writes: 'The underground explosion moves the rock, presses on it, and, in essence, squeezes the well's channel.' It's so simple, in fact, that the Soviet Union used this method five times to deal with petrocalamities, and it only didn't work once."

Scientology Tries To Block German Documentary 565

Posted by timothy from the piece-of-blue-sky dept.
eldavojohn writes "The Guardian is reporting on the strained relationship that Scientology is having with the German government and the airing of a pesky documentary on Southwest Broadcasting. Until Nothing Remains, a $2.3 million documentary, is slotted to air on German television at the end of this month. It recounts the true story of Heiner von Rönn and his family's suffering when he tried to leave the Church of Scientology. A Scientology spokesperson called the film false and intolerant and also said they are investigating legal means to stop the film from being aired. More details on the film can be gleaned here."

Massive Solar Updraft Towers Planned For Arizona 572

Posted by samzenpus from the juice-and-a-tan dept.
MikeChino writes "Australia-based EnviroMission Ltd recently announced plans to build two solar updraft towers that span hundreds of acres in La Paz County, Arizona. Solar updraft technology sounds promising enough: generate hot air with a giant greenhouse, channel the air into a chimney-like device, and let the warm wind turn a wind turbine to produce energy. The scale of the devices would be staggering — each plant would consist of a 2,400 foot chimney over a greenhouse measuring four square miles. The Southern California Public Power Authority has approved EnviroMission as a provider, although there’s still plenty of work to be done before the $750 million, 200 megawatt project can begin."

The Chinese Route To a Web Free of Porn 420

Posted by kdawson from the regarding-babies-and-bathwater dept.
An anonymous reader writes "Despite repeated 'for the children' campaigns, the Western Web as a whole has provided little or no isolation of pornography. This is why the Chinese are now attempting to march to a place where no country has been before: a Web without porn. Recent regulations have included closing down 'vulgar' mobile sites, disconnecting 'obscene' servers, and restricting domain registrations. Yet the breaking news for Monday is that China is planning to enforce a whitelist on foreign domains: in particular, any e-commerce will have to register locally and obey Chinese law before they get whitelisted. Domains will otherwise be 'irresolvable' to Chinese Internet users. Meanwhile, the government is promoting this campaign heavily, calling it a 'fresh start.' It seems the Chinese may have to do without the Internet, before they can rid it of porn."

Legislator Wants Cancer Warnings For Cell Phones 314

Posted by Soulskill from the reading-this-may-give-you-cancer dept.
Cytalk writes "A Maine legislator wants to make the state the first to require cell phones to carry warnings that they can cause brain cancer, although there is no consensus among scientists that they do and industry leaders dispute the claim. The now-ubiquitous devices carry such warnings in some countries, though no US states require them, according to the National Conference of State Legislators. A similar effort is afoot in San Francisco, where Mayor Gavin Newsom wants his city to be the nation’s first to require the warnings."
