(Phys.org) —A combined team of researchers from Harvard Medical School and several research institutions in Korea has developed a light-sensitive hydrogel that can be used as a cell based sensor. In their paper published ...
There are several ways to "trap" a beam of light—usually with mirrors, other reflective surfaces, or high-tech materials such as photonic crystals. But now researchers at MIT have discovered a new method to trap light that ...

(PhysOrg.com) -- A new study of a snake with tentacles on its snout has found it has a unique system for sensing prey: its tentacles allow it to "see" in murky water.
Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs.
