The mechanical properties of rubber can be improved by incorporating some filler material in the rubber matrix. Traditionally, carbon black is added to artificial rubber produced from styrene-butadiene which increases the tensile strength significantly. Carbon black, though, is typically produced from fossil fuels of some sort, so there’s interest in replacing it with a more Read More

Custom Stability Chamber Allows Neural Network Investigations
Brains are pretty complicated things. With all due deference to functional MRI studies and related localization-type studies, they do not have the resolution needed to investigate neural networks and their interconnections. Researchers at the Politecnico di Milano in Italy have developed a custom stability chamber that enables them to grow, sustain, and investigate neural networks. Read More

Evaluating Dental Implant Material in the Conditions They’ll Be Used
Several different composite materials can be used to produce dental implants. But if there’s one thing known about the environment in which they’ll be placed, it’s that it is warm and wet in there. So it really doesn’t matter what the implant material properties are at room temp in low humidity. The real question is, Read More

Stem Cell Therapy Offers Cheaper Alternative to Marrow Transplant
Blood marrow transplantation is an expensive, time-consuming process. If peripheral blood stem cells can be used instead, costs would be dramatically reduced. This is of particular interest in developing countries, where there are fewer resources available. A researcher at the Hospital Universitario UANL in Monterrey, Mexico investigated the effectiveness of the stem cell process. He Read More

Must See Video: Microscopic Cavitation Bubble Collapse
Ultrasonic cleaner videos are often exercises in patience. With little or no narration, parts are placed in the basin, the machine turned on, and dirt swirls away. Interesting that someone would make such a video, but not informative. Finally, a silent video about ultrasonic cleaning that is packed with information. This one is a simulation Read More

Hive Conditions Mitigate the Effects of the Varroa Destructor
The Varroa Destructor. It sounds like an invading scourge from outer space, or maybe a villain the Ghostbusters would encounter. When you see a photo of the varroa destructor, you might get that impression reinforced. In fact, it’s a nasty-looking eight-legged bee parasite, a mite that drinks the blood of developing larvae and adult drone Read More
