Predicting the impact of climate change on bridge safety

Climate change will increase the frequency and intensity of natural hazards like flooding. In turn, floodwaters erode a bridge's foundation, creating scour holes that compromise the integrity of the structure. But to date, it's been possible to quantify that scour risk. A new model developed by civil engineering researchers takes a holistic approach combining climatology, hydrology, structural engineering, and risk assessment to determine the effects of climate change on bridges.

New capsule can orally deliver drugs that usually have to be injected

MIT engineers designed a drug capsule that can carry insulin or other protein drugs and protect them from the harsh environment of the gastrointestinal tract. When the capsule reaches the small intestine, it breaks down to reveal dissolvable microneedles that attach to the intestinal wall and release drug for uptake into the bloodstream.

Stabilizing multilayer flows may improve transportation of heavy oils

During the past 20 years, the oil industry has begun to transition away from light oils toward heavier oils. But transporting heavy oils cost-effectively is a challenge because heavy oils are viscous — essentially a thick, sticky and semifluid mess. One way to outmaneuver this problem is a viscoplastic lubrication technique. It can complement existing methods to stabilize interfaces within multilayer flows.
