Portuguese designer Susana Soares has developed a device for detecting cancer and other serious diseases using trained bees. The bees are placed in a glass chamber into which the patient exhales; the bees fly into a smaller secondary chamber if they detect cancer.
Scientists have found that honey bees - Apis mellifera - have an extraordinary sense of smell that is more acute than that of a sniffer dog and can detect airborne molecules in the parts-per-trillion range.
Bees can be trained to detect specific chemical odours, including the biomarkers associated with diseases such as tuberculosis, lung, skin and pancreatic cancer.
At the U.S. Department of Energy’s Argonne National Laboratory, scientists have been experimenting with sound waves and pharmaceutical solutions, levitating soluble drops between two speakers facing each other. While their research has produced some visually fascinating results, it has also led to the discovery of a far more effective method for creating amorphous drugs, which happen to be the more desirable of two forms that pharmaceutical drugs can take.Watch Video Here.

This is the world’s smallest snowman - at 10 micrometres across, it’s only 1/5th the width of a human hair. The tiny guy was made from two tin beads used to calibrate electron microscope astigmatism. The eyes and smile were milled using a focused ion beam, and the nose, which is under 1 µm wide (or 0.001 mm), is ion beam deposited platinum.
Don’t you ever forget.
Scientists do whatever the fuck they want.
From a Pashtun point of view, Petraeus should be shot by relatives from his mistress’s family,” the Taliban official explained.
“From a Shariah point of view, he should be stoned to death.”
This picture is of a 2.5kg brick supported by a piece of aerogel, the worlds lightest solid material. This particular piece weighs in with a mass of 2 grams.
Aerogel is nicknamed ‘frozen smoke’ or ‘solid air’, due to the fact that it is composed of 99.98% air by volume. Aerogels are a diverse class of amazing materials with properties unlike anything else known. They exhibit the lowest thermal conductivity of any known solid, and are the lowest density structural materials ever developed.
Can the simple act of recognizing a face as you walk down the street change the way we think? Or can taking the time to notice something new on our way to work change what we remember about that walk? In a new study published in the journal Science, New York University researchers show that remembering something old or noticing something new can bias how you process subsequent information.
This novel finding suggests that our memory system can adaptively bias its processing towards forming new memories or retrieving old ones based on recent experiences. For example, when you walk into a restaurant or for the first time, your memory system can both encode the details of this new environment as well as allow you to remember a similar one where you recently dined with a friend. The results of this study suggest that what you did right before walking into the restaurant can determine which process is more likely to occur.
By contrast, in another experiment, the researchers demonstrated that the same manipulation can also influence how we form new memories. In this study, the researchers tested how well participants were able to form links between overlapping memories. They found that participants were more likely to construct these links when the overlapping memories were formed immediately after retrieving an unrelated old object as compared to identifying a new one. This suggests that after processing old objects, participants were more likely to retrieve the associated memories and link them to an ongoing experience.
