Curiosity has detected a surprising variety of organic molecules on Mars, including compounds tied to the chemistry of life. Some of these molecules may be billions of years old, preserved in ancient clay-rich rocks that once held water. One standout find resembles building blocks of DNA, raising exciting questions about Mars’ past. Although not proof of life, the discovery suggests the Red Planet may have once been far more biologically promising than we thought.

Scientists at MIT discovered that chaotic laser light can spontaneously form a highly focused beam instead of scattering—if the conditions are just right. This “pencil beam” enabled them to image the blood-brain barrier in 3D at speeds 25 times faster than existing techniques. The method also lets researchers watch how drugs move into brain cells in real time. It could dramatically accelerate the development of treatments for neurological diseases.
