The blood-brain barrier protects the brain from poisons but also prevents drugs from reaching brain tumors; innovative new treatments are needed. This laboratory study shows that a nanotechnology drug called SapC-DOPS crosses that barrier and targets brain-tumor cells and retards growth of tumor blood vessels. The findings also show how the agent targets tumor cells

The hydrogen economy that may one day replace the hydrocarbon economy came a step closer this week with the announcement that researchers have discovered an inexpensive new proton reduction catalyst – seventy times cheaper than the platinum commonly used now – that can significantly reduce the costs of producing hydrogen using electrolysis to split water

Bicycling can really be a pain in the legs. Your lower limbs pump endlessly to power the bike wheels over miles upon miles of terrain. Meanwhile, your arms just hang there doing little to nothing.

At Oregon Episcopal School, all students in 7th to 11th grade are required to enter a project in the Aardvark Science Expo
