It’s a skin disorder that makes life miserable for around 800 million teenagers and adults worldwide, but Australian scientists may have found an effective treatment for acne, delivered via tiny nanoparticles.

In a study led by the University of South Australia (UniSA), a new antibacterial compound known as Narasin was encased in tiny, soft nanoparticles 1000 times smaller than a single strand of human hair and applied in a gel form to targeted acne sites.

The drug — more commonly used in the livestock industry — proved successful against drug-resistant acne bacteria and delivered via nanocarriers achieved a 100-fold increase in absorption than simply taken with water.

The findings have been published in the journal Nanoscale...

In a new paper, researchers report a camera that could offer a much less expensive way to achieve ultrafast imaging for a wide range of applications such as real-time monitoring of drug delivery or high-speed lidar systems for autonomous driving. Researchers show that their new diffraction-gated real-time ultrahigh-speed mapping (DRUM) camera can capture a dynamic event in a single exposure at 4.8 million frames per second.

Herbig-Haro (HH) objects are luminous regions surrounding newborn stars, formed when stellar winds or jets of gas spewing from these newborn stars form shock waves colliding with nearby gas and dust at high speeds. This image of HH 211 from NASA’s James Webb Space Telescope reveals an outflow from a Class 0 protostar, an infantile analog of our Sun when it was no more than a few tens of thousands of years old and with a mass only 8% of the present-day Sun (it will eventually grow into a star like the Sun).

Infrared imaging is powerful in studying newborn stars and their outflows, because such stars are invariably still embedded within the gas from the molecular cloud in which they formed...

Researchers at the University of Washington have developed small robotic devices that can change how they move through the air by “snapping” into a folded position during their descent.

When these “microfliers” are dropped from a drone, they use a Miura-ori origami fold to switch from tumbling and dispersing outward through the air to dropping straight to the ground...
