HOW A MOVING PLATFORM FOR 3D PRINTING CAN CUT WASTE AND COSTS
3-D printing has the potential to revolutionize product design and manufacturing in a vast range of fields—from custom components for consumer products, to 3-D printed dental products and bone and medical implants that could save lives. However, the process also creates a large amount of expensive and unsustainable waste and takes a long time, making it difficult for 3-D printing to be implemented on a wide scale.
TINY BRAINS GROWN IN 3D-PRINTED BIOREACTOR
Scientists from MIT and the Indian Institute of Technology Madras have grown small amounts of self-organizing brain tissue, known as organoids, in a tiny 3-D-printed system that allows observation while they grow and develop. The work is reported in Biomicrofluidics.
INFERRING WHAT WE SHARE BY HOW WE SHARE
It’s getting harder for people to decipher real information from fake information online. But patterns in the ways in which information is spread over the internet—say, from user to user on a social media network—may serve as an indication of whether the information is authentic or not.

CURBING CORONAVIRUS SPREAD IN ENCLOSED SPACES MEANS BETTER MASKS, ADEQUATE VENTILATION
With research increasingly showing the COVID-19 virus is transmissible via smaller droplets suspended in air, there is a growing concern current public health guidelines of mask wearing and social distancing are insufficient in combating its spread in indoor environments, like prisons, hospitals, and meatpacking plants, where people tend to be in close quarters.
ACTIVATED CARBON INCREASES CRYOCOOLER EFFICIENCY
Cryocoolers are ultracold refrigeration units used in surgery and drug development, semiconductor fabrication, and spacecraft. They can be tubes, pumps, tabletop sizes, or larger refrigerator systems.
? EARTH NEWS?:
ANCIENT ATMOSPHERIC OXYGEN SLEUTHING WITH OCEAN CHROMIUM
Found in jewelry, car parts, pigments, and industrial chemical reactions, the metal chromium and its compounds are often employed for their color, finish, and anti-corrosive and catalytic properties. Currently, geoscientists and paleoceanographers from MIT and the Woods Hole Oceanographic Institution (WHOI) are looking to add another use to that list: as a way to examine chemical shifts in ancient Earth’s oceans and atmosphere that are preserved in the seafloor’s paleorecord. More specifically, they want to reconstruct rising atmospheric oxygen levels, which began around 2.4 billion years ago, and their effect on the seas. Since biology and the environment are intimately intertwined, this information could help illuminate how the Earth’s life and climate evolved.
DROUGHTS LONGER, RAINFALL MORE ERRATIC OVER THE LAST 50 YEARS IN MOST OF THE WEST
Dry periods between rainstorms have become longer and annual rainfall has become more erratic across most of the western United States during the past 50 years, according to a new study published by the U.S. Department of Agriculture’s Agricultural Research Service and the University of Arizona.

HUBBLE SPOTS DOUBLE QUASARS IN MERGING GALAXIES
Nasa’s Hubble Space
Telescope is “seeing double.” Peering back 10 billion years into the universe’s past, Hubble astronomers found a pair of quasars that are so close to each other they look like a single object in ground-based telescopic photos, but not in Hubble’s crisp view.
DARK ENERGY SURVEY PHYSICISTS OPEN NEW WINDOW INTO DARK ENERGY
The universe is expanding at an ever-increasing rate, and while no one is sure why, researchers with the Dark Energy Survey (DES) at least had a strategy for figuring it out: They would combine measurements of the distribution of matter, galaxies and galaxy clusters to better understand what’s going on.
? NANOTECHNOLOGY NEWS⛄☃:
HIGH-ORDER SUPERLATTICES BY ROLLING UP VAN DER WAALS HETEROSTRUCTURES
Two-dimensional (2D) materials and van der Waals (vdW) heterostructures are flexible materials with distinct atomic layers beyond traditional units of lattice-matching requirements. Nevertheless, the 2D van der Waals structures researchers have hitherto explored are limited to relatively simple heterostructures with a small number of blocks. It is exponentially more difficult to prepare high-order vdW superlattices with a myriad of alternating units due to their limited yield and the material damage associated with restacking or synthesis.
RESEARCHERS DEVELOP MATERIALS FOR ORAL DELIVERY OF INSULIN MEDICATION
A revolutionary technology developed within the Trabolsi Research Group at NYU Abu Dhabi (NYUAD) could dramatically improve the wellbeing of diabetic patients: an insulin oral delivery system that could replace traditional subcutaneous injections without the side effects caused by frequent injections.
