Developing new delivery tools for gene editing

Scientists are using simple peptides to deliver gene-editing tools into notoriously hard-to-access lung and airway cells with the goal of creating new treatments for people with diseases like cystic fibrosis, COPD, and asthma.

New technique lets researchers map strain in next-gen solar cells

Researchers have developed a way to map strain in lead halide perovskite solar cells without harming them. Their approach can image the grain structure of a perovskite solar cell, showing that misorientation between microscopic perovskite crystals is the primary contributor to the buildup of strain within the solar cell. Crystal misorientation creates small-scale defects in the grain structure,...

Are we 'brainwashed' during sleep?

A new study illustrates that the brain's cerebrospinal fluid pulses during sleep, and that these motions are closely tied with brain wave activity and blood flow. It may confirm the hypothesis that CSF flow and slow-wave activity both help flush toxic, memory-impairing proteins from the brain.

Spacewatch: Nasa tests new imaging technology in space

Operation was designed to test technology that allows multiple targets to be studied at same time Nasa launched its experimental Fortis (Far-ultraviolet Off Rowland-circle Telescope for Imaging and Spectroscopy) telescope on 28 October from the White Sands missile range in New Mexico.The flight lasted 15 minutes, reached 162 miles (260km) in altitude, and then fell back to Earth – exactly as...
