Electronic cuff in neck could keep blood pressure in check

High blood pressure can be a very serious condition, and is usually controlled via medication along with lifestyle changes. For approximately 35 percent of patients, however, that medication doesn't work in the long run. That's why a team of researchers from Germany's University of Freiburg are developing an implantable electronic cuff, that may one day control peoples' blood pressure via electrical pulses within the neck.

Researchers develop new microengine, but aren't sure how it works

If you’re going to do something like building a Porsche 911 that fits on the head of a pin, or make a microscopic medical pump, you need a microscopic engine. A team of researchers from the University of Twente in the Netherlands, the Russian Academy of Sciences, and Germany’s University of Freiburg have developed a micro-engine that burns oxygen and hydrogen, but there’s a small problem; they’re not sure how the thing works.

Charged polymers unlock door to deliver nanoparticles to cancer cells

In recent years, we've seen various research efforts looking to specifically target cancer cells as a replacement for the shotgun approach employed by chemotherapy that also damages healthy cells. The trick is to develop a delivery vehicle that identifies and targets only cancer cells, while ignoring the healthy ones. Researchers have found charged polymers have this ability, opening the door for nanoparticles containing cancer-fighting drugs to deliver their payload directly to the cancer cells.Read More

Pomelo fruit inspires high-strength hybrid metal

Here's an interesting fact about the pomelo fruit: even though a mature fruit can weigh up to 2 kg (4.4 lb), they remain intact after falling from heights of over 10 meters (33 ft). The secret lies in the structure of their peel. Scientists have copied that structure, to produce a new type of aluminum composite that's stronger than straight aluminum. Read More

New surface coatings give insects the slip

Not having air conditioning in my house, here's something I didn't know: the inner surfaces of air conditioner ventilation pipes are often covered in cockroaches. Nice. In order to keep the roaches out of those pipes – along with keeping other insects out of other places – scientists from Germany's University of Freiburg have developed new bio-inspired surface coatings that even sticky-footed bugs can't cling to.

German scientists create usable foam from tree bark

Germany is known for its cutting-edge policies on green issues, and its drive towards a clean economy. One of its latest eco-breakthroughs comes from the University of Freiburg's Biofoambark project. Researchers there are trying to green up the insulation foam used in construction, by replacing its petroleum-based ingredients with a naturally-occurring compound that ordinarily goes to waste in the lumber industry.
