Algae Could Be the Key To Ultra-Thin Batteries 54

MikeChino writes "Algae is often touted as the next big thing in biofuels, but the slimy stuff could also be the key to paper-thin biodegradable batteries, according to researchers at Uppsala University in Sweden. Uppsala researcher Maria Stromme and her team has found that the smelly algae species that clumps on beaches, known as Cladophora, can also be used to make a type of cellulose that has 100 times the surface area of cellulose found in paper. That means it can hold enough conducting polymers to effectively recharge and hold electricity for long amounts of time. Eventually, the bio batteries could compete with commercial lithium-ion batteries."

...there are regions of India the size of Canada where you really shouldn't try it.

Canada has more than three times the land mass of India.

That pertains to infidelity, not homosexuality.

Slashdot doesn't render properly in Safari 4 or Firefox 3.5 beta4 either - the comment titles and scores aren't displayed anymore

The comment titles and scores are being rendered (highlight the page with ctrl-a), the problem is with the CSS - the background image that runs the length of the div element containing the title is being overwritten. This:

.comment div.title { background:#044 url("//c.fsdn.com/sd/article-title-bg.png") repeat-x left top; }

get's overwritten by this (appears further down the document):

.comment div.title { background:#fff!important; }

You'll notice the issue doesn't occur on some of the alternative stylesheets (Ask Slashdot, YRO, etc). In the meantime, you can hit 'change' in the threshold form to set things straight.

> This left the shortest dial time area code for a statewide code as 201..

Have you ever actually seen a rotary phone? Dialing "0" is the slowest digit of all. It's placed after the "9".

Keep in mind that he said that statewide area codes (ie. area codes that every phone number in the state used) had to have 0 as the middle digit. So while 201 wouldn't be faster to dial than 212, it is the fastest statewide area code (since 1 wasn't available as the first digit).

Submission + - RIAA Steps on Attack on Multiple Sclerosis Mom

NewYorkCountryLawyer writes: "The RIAA has stepped up its attack on a Queens, New York, mother who suffers from Multiple Sclerosis, and who never even heard of file sharing, in Elektra v. Schwartz, a Brooklyn federal court case in which a Guardian Ad Litem had been appointed to protect the interests of the defendant. The RIAA is now seeking to go ahead with discovery of defendant's hard drive with a "John Doe" proceeding. This is the same case in which the RIAA had written a letter to the Judge mischaracterizing the contents of a letter it had received from AOL."
