Submission + - The physics of beer bubbles

Roland Piquepaille writes: "Yesterday, I told you about virtual beer. Today, let's follow two North America researchers who are studying the physics of real beer bubbles. 'Singly scattered waves form the basis of many imaging techniques such as radar or seismic exploration.' But pouring beer in a mug involves multiply scattered acoustic waves. They are more complex to study, but they can be used to look at various phenomena, such as predicting volcanic eruptions or understanding the movement of particles in fluids like beer. They also could be used to monitor the structural health of bridges and buildings or the stability of food products over time. Read more for additional references and a photo showing how the researchers monitor beer bubbles."

Submission + - The Physical Hacks at DefCon (physorg.com)

eldavojohn writes: "As we all know, DefCon is occurring in Vegas this weekend but Saturday held a room that focused on possibly the oldest form of hacking — lockpicking. That's right, as software security becomes better and better, the focus may instead shift towards simple hacking tips like looking over someone's shoulder for their password, faking employment or just picking the locks to gain access to the building where machines are left on overnight. This is nothing to sneeze at, "Medeco deadbolt locks relied on worldwide at embassies, banks and other tempting targets for thieves, spies or terrorists can be opened in seconds with a strip of metal and a thin screw driver, Marc Tobias of Security.org demonstrated for AFP ... Tobias says he refuses to publish details of 'defeating' the locks because they are used in places ranging from homes, banks and jewelers to the White House and the Pentagon. He asked AFP not to disclose how it is done." I'm sure all Slashdot readers are savvy enough to use firewall(s) but do you know and trust what locks 'physically' protect your data from hacks like these?"

House Approves Warrantless Wiretapping Extension 342

An anonymous reader writes "The House of Representatives voted 227-183 to update the Foreign Intelligence Surveillance Act (FISA) to allow warrantless wiretapping of telephone and electronic communications. The vote extends the FISA amendment for six months. 'The administration said the measure is needed to speed the National Security Agency's ability to intercept phone calls, e-mails and other communications involving foreign nationals "reasonably believed to be outside the United States." Civil liberties groups and many Democrats said it goes too far, possibly enabling the government to wiretap U.S. residents communicating with overseas parties without adequate oversight from courts or Congres.'"

In Australia, An Ebay Sale is a Sale 267

syousef writes "An eBay sale is a sale says an Australian New South Wales State Judge in a case where a man tried to reneg on the Ebay sale of a 1946 World War II Wirraway aircraft. The seller tried to weasel out of the deal because he'd received a separate offer $100,000 greater than the Ebay sale price. The buyer who had bid the reserve price of $150,000 at the last minute took him to court. 'It follows that, in my view, a binding contract was formed between the plaintiff and the defendant and that it should be specifically enforced,' Justice Rein said in his decision." I haven't found anything like this in previous discussions; have there been similar decisions like this handed down in the US, Canada, or Europe?
