Jonathan Hopkins of the University of California, Los Angeles and associates report a scalable method to assembling 3D arrays of microgranular crystals utilizing holographic optical tweezers. Vascular networks are central parts of organ‐on‐a‐chip methods.

Ebony McIntosh devotes her time — and her house — to look after sick and injured microbats. She explains what’s concerned in bat rescue and why she is so passionate about saving these animals. Experts say regardless of current headlines we still don’t know how lengthy our immunity to COVID-19 lasts they usually’re still optimistic a few vaccine. This edition of Pioneers in Science celebrates physicist Wilhelm Röntgen, winner of the 1901 Nobel Prize in Physics for his discovery of “a brand new kind of ray”.

This SEM picture comes courtesy of Roey Elnathan and Nicolas Voelcker at Monash University, and their co-workers, demonstrating using vertical silicon nanotubes (SiNTs) to govern cell progress and gene enhancing by way of intracellular delivery of small molecules. The large scale bar represents 10 µm, whilst the size bar within the inset represents simply 2 µm.

A solar probe constructed by NASA and the European Space Agency delivers the closest photographs ever taken of the Sun’s floor, revealing tiny explosions on the floor known as nanoflares. Three new spacecraft are launching to Mars this month and every of them will take a look at new technologies in the race to achieve the Red Planet next 12 months, on a quest to search out evidence of previous life. We clarify the missions and why July is the month to journey.

The planks in this “woodpile” design are a mere 30 nanometers apart from one another. Frederik Mayer and Martin Wegener of Karlsruhe Institute of Technology, and their co-employees constructed this tiny object using a new materials for 3D printing. Xiaohu Gao from the University of Washington and co-workers mix two highly effective applied sciences; quantum dots and a way for amplifying the fluorescence given off by imaging molecules, called signal amplification by exchange reaction (SABER).
