Imagine having an entire pharmacy’s worth of drugs implanted in your body primed for release upon demand. It’s like a medical “OnStar”. This idea of an implantable microchip for programmable multi-dose drug delivery finally shows proof of concept with the osteoporosis drug teriparatide.
Wonder what a comparison of helmet impact forces between high school, college, and NFL football players by position would look like?
Alumina nano-straws help facilitate delivery of small molecule drugs at the cellular level, without inhibiting cell growth.
New discovery reveals the lubricating layer formed on implanted prosthetic joints with metal-on-metal contacts is a thin layer of carbon. Reminds me of graphite lubricant used on pinewood derby cars.
Researchers from Rice University and Baylor College of Medicine have developed a method to grow blood vessels in a laboratory. The investigators used biomimetic polyethylene glycol hydrogels embedded with a growth factor called BB (PDGF-BB) to spur angiogenesis, and are now working on a way to guide the formation of vasculature for specific applications

Fluorescent Nanoparticles Fresh From The Microwave
To make the particles, Mao, with Shukun Xu and colleagues in China, mixed acetates of the rare earth elements yttrium, ytterbium, and erbium; NH4F; and NaCl in the microwave at 160 °C for one hour. The resulting nanoparticles, he says, are comparable in quality to those made under more stringent conditions. The researchers then attached the nanoparticles to antibodies and used the resulting complexes to label cells in a petri dish. How they will fare in vivo remains to be seen, Mao says.

Nitric Oxide-Emitting Nanomaterials Kill Microbes
Need to track your blood oxygen levels? There may soon be an app for that.
How to build a new breast
The researchers got some brave specimens to move a mouse cursor by implanting plastic pads containing electrodes underneath their skulls, with the sensors sitting on the surface of the brain.
What kind of scientist are you?
“Yet in all the questioning posed by the serious professors, and in all the fear that the student was experiencing, there was an elephant in the room that nobody discussed: was the hypothesis good enough to begin with? Were the questions really worth asking? If they weren’t, how would he improve them?”
