Measuring time without a clock

Scientists have been able to measure the ultrashort time delay in electron photoemission without using a clock. The discovery has important implications for fundamental research and cutting-edge technology.

Overcoming hurdles in CRISPR gene editing with nanoparticles

Scientists have designed a delivery system using nanoparticles to assist CRISPR/Cas9 across the membrane and into the cell nucleus while avoiding entrapment by cellular machinery.

Material can turn sunlight, heat and movement Into electricity - all at once

Researchers have found that a mineral with the perovskite crystal structure has the right properties to extract energy from multiple sources at the same time.

Tarantulas inspire new structural color with the greatest viewing angle

Inspired by the hair of blue tarantulas, researchers made a structural-colored material that shows consistent color from all viewing directions. This finding overturns the conventional wisdom that long-range order photonic structures are always iridescent.

Serial killers of the immune system caught on microscopic CCTV

Scientists have filmed the process by which lymphocytes drill holes in their victims, laying bare key steps taken by the immune system to rid our body of harmful invaders.

DNA 'barcoding' allows rapid testing of nanoparticles for therapeutic delivery

Using tiny snippets of DNA as 'barcodes', researchers have developed a new technique for rapidly screening the ability of nanoparticles to selectively deliver therapeutic genes to specific organs of the body.

Ultrasmall atom motions recorded with ultrashort x-ray pulses

In a novel type of experiment, regularly arranged atoms in a crystal are set into vibration by a laser pulse and a sequence of snapshots is generated via changes of x-ray absorption.

The science and engineering of quantum dot lasers

From the beginnings of research to practical applications.
