HIV Test for Everyone?

CDC Recommends it for Everyone between 13 and 60 This seems like a very expensive proposition. It appears more people are living with this virus without knowing about it.

"The most rigorously refined experiment to date."

The Ganzfeld Experiment. Is it evidence for the existence of psi abilities? Is it sloppy experimental practice? Philosopher and game designer Chris Bateman suggests that it might be most significant for what it reveals about the biases of the scientific community.

Science Live

Science Live site I found this because of the live coverage of the Festival of Science 2006 from Norwich, but found lots of other great links! Great for kids, but good for anyone curious about science. "What if you could watch any popular science lecture you wanted to? What if you could participate in any popular science event? What if you could find out what scientists themselves have to say about the issues that are important in society today? ScienceLive is an initiative that seeks to bring some of the best popular science events (discussions, lectures, interviews) directly to your home, so that you can watch these events whenever and from whereever you can.

"Einsteinbrain!"

Japanese professor Kenji Sugimoto has a long-standing fascination with the brain of Albert Einstein. In the early nineties he travelled to the United States in search of it. This bizarre 1994 documentary (YouTube, multiple parts) by Kevin Hull (UK) chronicles his quest. Fake or real? [more inside]

'It has lumps'

GRACE is fine-tuning our understanding of Earth's gravity. It also shows that Greenland's ice is melting, how the recent Sumatra earthquake changed the earth, and provides information on the world's oceans and climate.

So, what do you think?

Some online journals, such as Ecology and Society, operate independently. Others are hosted collectively by interests like Copernicus Publications. Online peer review is becoming popular.

Human Rights Watch, Watched

Human Rights Watch, Watched "Who will guard the guardians?" asked Roman satirist Juvenal. Now we must ask, who is watching Human Rights Watch, one of the world's best-financed and most influential human rights organizations? It turns out that they cook the books about facts, cheat on interviews, and put out pre-determined conclusions that are driven more by their ideology than by evidence. These are serious accusations, and they are demonstrably true.

Breaking the Laws of Physics?

Free Energy? Family Guy viewers already know that Ireland's top scientists once discovered how to turn their population into pure energy, but have they now discovered the key to perpetual motion? The Law of Conservation of Energy would seem to suggest otherwise, but these fellas (Google video) would seem to claim otherwise. Steorn, an Irish "technology development" company, claims that they have discovered a means to free energy, and have issued a challenge to the scientific community.

PV=nRT: It's not just a good idea....

200 liters of condensed liquid nitrogen (LN2) were delivered to Berkeley’s Condensed Matter Lab this past Monday. Sent to retrieve the 400lb dewar from the loading dock but faced with a non-working elevator, an enterprising young lab student decided to carry it down the stairs. Gravity is a harsh mistress.

If things had turned out differently, they could have been scraping his remains off the walls with a spatula. At Texas A&M in January a lab was badly damaged when someone ignored the Ideal Gas Law, removed the pressure valve and rupture disk off an old (LN2) tank and filled the remaining holes with metal plugs. "How to Tell a True Lab Story" talks about a similar incident. LN2 is good for more than just blowing up a school (or, um a watermelon), though: Spanish Chef Ferran Adrià uses it to create dishes at his restaurant. Previously on MeFI: How to make LN2 ice cream (careful!) and unwise science experiments.

The story of motion

Motion Mountain - "The project aims to produce a simple, vivid and up-to-date introduction to modern physics, with emphasis on the fundamental ideas of motion. 'Simple' means that concepts are stressed more than formalism; 'vivid' means that the reader is continuously challenged; 'up-to-date' means that modern research and ideas about unification are included."

Whale evolution

Whales are ridiculous, thanks to their evolutionary origins as coyote-like mammals moved into the water about 45 million years ago and became more and more adapted to the marine life.

The water is reversible, but time is not...

"The trick to education is to teach people in such a way that they don't realize they're learning until it's too late."
Fluorescein-dyed water appears suspended in midair, only to "flow" upwards moments later. The careful dance of a splashing drop is frozen and taken for granted, painstakingly analyzed in a brilliant defiance of how water should behave. Such is the wonder of what modder Nate True calls his Time Fountain (YouTube embedded & worth it)—a well-documented, DIY version of classic science center favorite, the Water Piddler. MIT's own Strobe Alley is lined with photos created using the same technology, pioneered by Harold Eugene Edgerton, a professor whose work you're almost certainly familiar with. Naturally, some beautiful pieces have followed under the same ideal, courtesy Martin Waugh.

What Peace Did Hizbullah Shatter?

What peace did Hezbollah Shatter? asks Anders Stringberg in the Christian Science Monitor, a paper that has won the Pulitzer seven times and is particularly well-known for its in-depth coverage of the Middle East. Relying on the most recent United Nations Interim Force In Lebanon (UNIFIL) report , Strindberg believes that Hezbollah's attacks stem from Israeli incursions into Lebanon. In the same publication, another commentator says that the latest Levantine crisis is a 'moment of opportunity' but only if the U.S. asks Israel the hard questions.

Rangaku - Dutch Learning

Rangaku (literally "Dutch Learning") refers to the body of knowledge developed in Japan during the Sakoku period (1641-1853) during which the country was closed to foreigners. As the Dutch trading post at Dejima was effectively an enclave of the Netherlands, for 212 years it was just about Japan's only way to keep tabs on European scientific progress (pdf). Rangaku has influenced Japanese medicine, anatomy, engineering, meteorology, and chemistry, among other fields.

Half-Life? Try Sixteenth-Life

Chilling Out Mr. Radioactive
A group of scientists at Germany's Ruhr University may have a way of cutting down the time it takes for radioactive waste to decay to a safer state. Instead of 1600 years for Radium-226, Prof. Claus Rolfs theorizes that he can cut that down to a mere 100 years, by encasing the materials in metal and then freezing them to very, very low temps to accelerate the radioactive decay.

Scientists say they’ve found a code beyond genetics in DNA

Scientists say they’ve found a code beyond genetics in DNA. The study by Segal et al. [PDF] establishes a model for predicting some (but not all) nucleosome placement. This is critical for understanding the regulation of gene expression.

I'm absolutely sure that no antibody test in medicine has any absolute meaning.

Dr. Stephen Lanka claims that H5N1 doesn't exist. Or AIDS. Or disease-causing viruses in general. "In humans, in the blood or in other bodily fluids, in an animal or in a plant there never have been seen or demonstrated structures which you could characterize as bird flu viruses or flu viruses or any other supposedly disease-causing virus. The causes of those diseases which are being maintained to be caused by a virus, also those in animals, which can arise quickly and in individuals either one after the other or several at the same time, are known since a long time back. However much you stretch things in biology, there is simply no place for viruses as the causative agents of diseases. Only if I ignore the findings of Dr Hamer’s New Medicine, according to which shock events are the cause of many diseases, and the findings of chemistry on the effects of poisonings and deficiencies, and then if I ignore the findings of physics about the effects of radiation, then there is a place for imaginings such as disease-causing viruses."

Politics at the FDA

"In 2006, the Union of Concerned Scientists (UCS) and Public Employees for Environmental Responsibility (PEER) distributed a 38-question survey to 5,918 FDA scientists to examine the state of science at the FDA. The results paint a picture of a troubled agency: hundreds of scientists reported significant interference with the FDA’s scientific work, compromising the agency’s ability to fulfill its mission of protecting public health and safety."

and lawnmowers everywhere fall into disrepair

The end of the lawnmower era is nigh. Microbiologist Joanne Chory may change the face of suburban one-upmanship as we know it. Imagine a weekend morning without the sound of lawnmowers. Can it really be just around the corner? Will men be willing to terminate their love/hate (mpg) relationships with their lawns? After all, a man and his mower are not easily parted.

The Blue People of Troublesome Creek

Martin and Elizabeth set up housekeeping on the banks of Troublesome and began a family. Of their seven children, four were reported to be blue.

For those unfamiliar with the story of Martin Fugate & his descendents, the 1982 article from Science magazine entitled "The Blue People of Troublesome Creek" is a fascinating read; a recessive gene & decades of inbreeding lead to a clan of Kentucky hill folk with deep blue skin from head to toe.

The New "Science" of Siblings An amusing article from Time magazine by Jeffrey Kluger which reports that your siblings have more influece on your personality than any other group-- parents, peers, spouses, children, etc. My ex-wife thinks I'm sarcastic, combative, insensitive, etc. Do I get to blame my brothers and sisters for this now?

Sources: Personal Opinion.

We need to get Stephen Hawking an AskMe membership. Stephen Hawking asks the Yahoo public how the human race is going to survive. Yahoo staff are excited. But the answers? Well, let's just say that there may be more utility in eating tweens after the nuclear apocalypse than listening to their ideas. To balance the stupid, Hawking has several of his lectures online. And there's great stuff on PBS's Stephen Hawking's Universe (though it's aimed at providing a basic understanding of astrophysics). Or, for a more animated view MC Hawking's (sometimes clumsy) "What We Need More of Is Science. (Previous mefi hawking here, here [where he seems to be answering his later question], here [where he presents another view on how humans will survive], and here.)

Restoration by Animation.

Fill in the blanks, connect the dots. We've had Star Trek special effects possibly redone, we've had Battlestar Galactica "reimagined". Now the BBC is replacing a couple of lost episodes in a live series Doctor Who DVD with animated versions, to match the soundtracks, which weren't lost. Of course, we've seen some Flash based episodes already.

A technological Hero

Leonardo is overrated: the steam turbine was invented two millennia ago by Hero of Alexandria who developed the aeolipile as a toy. Hero was also responsible for the first vending machine (for holy water) and hydraulic automatic temple doors, along with advances in areas as diverse as physics and mathematics. A translation of Hero's influential Pneumatics is available online, featuring illustrated examples of many of his inventions, many of which are related to clever devices for drinking or prayer, or both.
