A study recently published in the Journal of Complementary and Alternative Medicine found that 28% of subjects prescribed St. John’s Wort for depression were also taking drugs with a potentially dangerous interaction.
The SGU, together with George Hrab from the GeoLogic podcast, will be making a tour down under this Fall. We will be in Sydney, Australia November 28-30, 2014 at the Australian Skeptics National Conference. The following weekend we will be in Auckland, New Zealand December 5-7 at the New Zealand Skeptics Conference.
Physicist claims evidence that light is just a little bit slower than we think
Do you remember 1987? I do. That was the year of we detected the closest Supernova in 383 years. It was the first time that advanced human astronomers had a real close view of one. I even
threw a party (no I didn’t). It wasn’t in the Milky Way unfortunately. It was in a nearby (160,000 light years distant) dwarf galaxy called the Large Magellanic Cloud.
It was quite a week for ridiculous statements. As usual, there is no shortage of mind-boggling ideas floating around the internet.
Researchers have detected the smallest force ever measured using lasers and a super-cold gas trapped by waves of light.
This force is so small you’ve probably never even heard it before. We’re talking about a force of 42 YoctoNewtons (I promise that’s not made up). One yoctonewton is a septillionth of a newton or about a thousand billion billion times less than a feather lying on your desk. For some useless perspective, one newton of force is a little more than what’s needed to depress a key on a keyboard
Why heat a whole room when you can heat just the people in it?
This is an interesting idea I had never considered before. Certain spaces are especially expensive to heat like office building lobbies. MIT has a lab that has created a concept called Local Warming in which a special motion sensing heat lamp can detect people and aim at them to keep them warm.
You’ve heard of invisibility cloaks? Scientists have created a meta-material unfeelability cloak that prevents feeling anything underneath it.
Meta-materials are the darling of material science. Fabricated painstakingly and complexly at the micro-scale, they exhibit behaviors truly foreign to anything found in nature. Great
advances have been made using them to bend light, heat, or sound around objects making them essentially invisible to certain modes of perception.
