The average U.S. suburban house requires about 45 kilowatt hours of electricity per day. But according to this post by Treehugger, a model home on display at the National Building Museum in Washington can run on a miserly 800 watt hours a day. One of the many corner-cutting secrets: A stove with a built-in toaster.
Some of the most fascinating photography, as we have shown in this space, comes from deep beneath the sea. And no one knows this better than the people at a U.K. organization called SERPANT, which describes itself as a scientific and environmental partnership. So they began a competition for underwater photography and video, and it has drawn some amazing entries.
As you swelter in the mid-summer heat, it may (or may not) be of interest to know that humankind has been obsessed with the science of weather for centuries. The evidence can be found in this post by BibliOdyssey, which includes pages from reference books dating back to the 1600s from around the world that examine the origins of everything from lightning to hurricanes.
Radioactive venom from an Israeli scorpion species might not be the first thing one would think of to treat a form of brain cancer called glioma. A company called TransMolecular that's pushing the idea, though, announced "favorable safety results" from a second-phase trial of such a substance (click for PDF).
The substance, called 131I-TM-601, is actually a synthetic version of a chemical in the scorpion venom. It's coupled with a radioactive isotope of iodine with an atomic weight of 131. The 131I-TM-601 binds with receptors in the cancer cells but leaves healthy cells alone, TransMolecular said. … Read more
Haifa, Israel--There are a lot of nasty things in the water supply, but experts have begun to focus on something many didn't recognize as a problem a few years ago: medicines.
Drugs ingested by people or pets and then eliminated through digestion has become a significant concern, according to Carlos Dosoretz, an associate professor of civil and environmental engineering at the Technion, Israel's premier engineering university.
"Female hormones, all kinds of antibiotics, cholesterol regulators," he said. "It is a new problem because we now have the analytic instruments to detect it."
The increase in … Read more
A new computer model of the Antarctic ozone hole shows it's in worse condition than previously thought.
A hole in the upper atmosphere over Antarctica will not clear up before 2068, roughly 18 years later than earlier estimates, according to a new computer simulation developed by scientists at NASA, the National Oceanic and Atmospheric Administration (NOAA) and the National Center for Atmospheric Research (NCAR). Expectation for the hole to disappear has come from the Montreal Protocol, an international agreement adopted in 1987 that first limited and then banned production of ozone-depleting substances like chlorofluorocarbons (CFCs)--a chemical that causes … Read more
In the ultracompetitive college entrance exams this month, students raised the practice of cheating to a high-tech art form with microscopic earphones and wireless networks. But in the process, according to the China Daily newspaper, some ended up being hospitalized when the homemade devices went awry in their aural canals.
Some bloggers doubted the veracity of these injury reports, attributing them to propaganda by Chinese officials seeking to curb the widespread cheating. But so pervasive has the practice become that universities had announced plans to block mobile-phone signals earlier this … Read more
This post may have gained interest since the recent controversy stirred by Stephen Hawking about settling in outer space. Skyetis, described as "a school project taken to another level," offers a Photoshop tutorial that shows how to create your own planet.
