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.

Simply by adding sugar, researchers from the Monash Energy Institute have created a longer-lasting, lighter, more sustainable rival to the lithium-ion batteries that are essential for aviation, electric vehicles and submarines.
The Monash team, assisted by CSIRO, report in today’s edition of Nature Communications that using a glucose-based additive on the positive electrode they have managed to stabilize lithium-sulfur battery technology, long touted as the basis for the next generation of batteries.
“In less than a decade, this technology could lead to vehicles including electric busses and trucks that can travel from Melbourne to Sydney without recharging. It could also enable innovation in delivery and agricultural drones where light weight is paramount,” says lead author Professor Mainak Majumder, from the Department of Mechanical and Aerospace Engineering and Associate Director of the Monash Energy Institute.

It’s an old adage: there’s no harm in getting a second opinion. But what if that second opinion could be generated by a computer, using artificial intelligence? Would it come up with better treatment recommendations than your professional proposes?
