Cold clouds of atoms—Bose-Einstein Condensates—will test quantum gravity, enable atom-scale lithography and prospect for minerals from afar.
A team of researchers from Texas A&M University’s Department of Biomedical Engineering has designed and 3D bioprinted a highly realistic model of a blood vessel.
The model is made of a newly nanoengineered, purpose-built hydrogel bioink and closely mimics the natural vascular function of a real blood vessel, as well as its disease response. The team hopes its work can pave the way for advanced cardiovascular drug development, expediting treatment approval while eliminating the need for animal and human testing altogether.
“A remarkably unique characteristic of this nanoengineered bioink is that regardless of cell density, it demonstrates a high printability and ability to protect encapsulated cells against high shear forces in the bioprinting process,” said Akhilesh Gaharwar, associate professor at the university and co-author of the study. “Remarkably, 3D bioprinted cells maintain a healthy phenotype and remain viable for nearly one month post-fabrication.”
The UK Space Agency tweeted: “We are monitoring its re-entry together with @DefenceHQ, and there is no expectation the re-entry will cause any damage. Due to the varying input data, natural forces and associated observation error, there are always high levels of uncertainty when performing re-entry predictions on any satellite”.
“Today, a Starlink-1855 satellite re-entered the Earth’s atmosphere. There is a chance it will re-enter over the UK, and you might be able to spot the satellite as it burns up. Starlink has a fantastic track record or orchestrating safe and reliable re-entries. We do not expect the return of the satellite to cause any damage. Still the UK Space Agency and the Ministry of Defence continually monitor and assess the re-entries of satellite and debris and any risk to British territories through our joined Space Surveillance and Tracking capabilities”.

Forget about online games that promise you a “whole world” to explore. An international team of researchers has generated an entire virtual universe, and made it freely available on the cloud to everyone.
Uchuu (meaning “outer space” in Japanese) is the largest and most realistic simulation of the universe to date. The Uchuu simulation consists of 2.1 trillion particles in a computational cube an unprecedented 9.63 billion light-years to a side. For comparison, that’s about three-quarters the distance between Earth and the most distant observed galaxies. Uchuu reveals the evolution of the universe on a level of both size and detail inconceivable until now.

SpaceX is gearing up for its first purely commercial human spaceflight, but many details about the mission remain unclear.
On the Outskirts of the Nucleus If you open a biology textbook and run through the images depicting how DNA is organized in the cell’s nucleus, chances are you’ll start feeling hungry; the chains of DNA would seem like a bowl of ramen: long strings floating in liquid. However, according to two new.
WASHINGTON — NASA has selected SpaceX to launch the last in a series of geostationary weather satellites that had previously been launched by United Launch Alliance.
NASA announced Sept. 10 that it awarded a contract to SpaceX for the Falcon Heavy launch of the Geostationary Operational Environmental Satellite (GOES) U spacecraft. The launch is scheduled for April 2024 from the Kennedy Space Center in Florida. The agency said the contract is valued at $152.5 million.
GOES-U is the fourth and final satellite in the GOES-R series of satellites, which monitor terrestrial and space weather from geostationary orbit. GOES-R launched in November 2016 and was renamed GOES-16, operating from the GOES East slot at 75 degrees west in GEO. GOES-S launched in March 2018 and became GOES-17, operating from the GOES West slot at 137 degrees west. GOES-T is scheduled to launch in January 2022 and will replace GOES-17 because of problems with that satellite’s main instrument, the Advanced Baseline Imager.
