SUSIE’s vertical landing capabilities draw comparisons to SpaceX’s Starship. Europe’s not quite there yet, but it’s a step in the right direction.
French aerospace giant ArianeGroup revealed a new concept for a reusable upper-stage spacecraft called Smart Upper Stage for Innovative Exploration, or SUSIE.
Elon Musk said the “next big test” is likely a full stack wet dress rehearsal of Starship.
SpaceX’s massive Starship rocket continues to pass key tests on its road to sending the Mars-bound launch system up to orbit for the first time.
The private space firm fired seven Raptor engines on its Starship Super Heavy prototype, called Booster 7, on Monday, September 19. As Space.com points out, it is the highest number of next-generation engines ever tested simultaneously.
Recovery of the Antarctic ozone layer is anticipated to take place sometime around 2070.
The depletion of the ozone layer had a huge impact on humanity for a while. Moreover, the United Nations accepted The International Day for the Preservation of the Ozone Layer in 1994.
Every living thing on Earth is shielded from UV radiation by the stratospheric ozone layer. Thus, the Ozone Layer is vital for all forms of life, and we need to protect it without a doubt.
Webb can image the entire planet at once in high resolution at a short exposure time, allowing for the study of dust storms, weather patterns and seasonal changes.
The James Webb Space Telescope has captured its first images and spectra of Mars, revealing atmospheric data that previous instruments couldn’t detect.
Captured with its Near InfraRed Camera, or NIRCam instrument from JWST’s position around a million miles (1.6 million kilometers) from Mars, on September 5, along with data from its Near InfraRed Spectrometer (NIRSpec), the images were released on Monday, September 19, at the Europlanet Science Congress 2022.
Markets have been down but Meta’s stock price loss is astounding.
Facebook founder Mark Zuckerberg’s personal worth has eroded by a whopping $71 billion dollars in 2022 alone, the most for any billionaire as tracked by Bloomberg.

The genetic encoding of ncAAs with distinct chemical, biological, and physical properties requires the engineering of bioorthogonal translational machinery, consisting of an evolved aminoacyl-tRNA synthetase/tRNA pair and a “blank” codon. To achieve this, the researchers mimicked the ibis’ ability to synthesize sTyr and incorporate it into proteins.
The Xiao lab employed a mutant amber stop codon to encode the desired sulfotransferase, resulting in a completely autonomous mammalian cell line capable of biosynthesizing sTyr and incorporating it with great precision into proteins.
These engineered cells, the authors wrote, can produce “site-specifically sulfated proteins at a higher yield than cells fed exogenously with the highest level of sTyr reported in the literature.” They used the cells to prepare highly potent thrombin inhibitors with site-specific sulfation.
The pursuit of a cure for Alzheimer’s disease is becoming an increasingly competitive and contentious quest with recent years witnessing several important controversies.
In July 2022, Science magazine reported that a key 2006 research paper, published in the prestigious journal Nature, which identified a subtype of brain protein called beta-amyloid as the cause of Alzheimer’s, may have been based on fabricated data.
One year earlier, in June 2021, the US Food and Drug Administration had approved aducanumab, an antibody-targeting beta-amyloid, as a treatment for Alzheimer’s, even though the data supporting its use were incomplete and contradictory.
Language is the most intuitive way for us to express how we feel and what we want. However, despite recent advancements in artificial intelligence, it is still very hard to control a robot using natural language instructions. Free-form commands such as “Robot, please go a little slower when you pass close to my TV” or “Stay far away from the swimming pool!” are hard to parse into actionable robot behaviors, and most human-robot interfaces today still rely on complex strategies such directly programming cost functions which define the desired behavior.
With our latest work, we attempt to change this reality through the introduction of “LaTTe: Language Trajectory Transformer”. LaTTe is a deep machine learning model that lets us send language commands to robots in an intuitive way with ease. When given an input sentence by the user, the model fuses it with camera images of objects that the robot observes in its surroundings, and outputs the desired robot behavior.

Wait, what? really?
For the first time, scientists were able to create particles without precursor particles or colliding two quanta together. Using the Schwinger effect, they could create matter with the aid of electromagnetic fields.
Young people seeking to slake their curiosity are increasingly turning to TikTok as a substitute search engine, with the addictive video-sharing app filled with everything from fried chicken recipes to music history deep dives. This is typically fine if you’re just after movie recommendations or a place to have lunch. Unfortunately, new research by NewsGuard has found TikTok also contains a concerning volume of misinformation about serious topics.
When looking for prominent news stories in September, the fact checking organisation found misinformation in almost 20 percent of videos surfaced by the app’s search engine. 540 TikTok videos were analysed as part of this investigation, with 105 found to contain “false or misleading claims.”
“This means that for searches on topics ranging from the Russian invasion of Ukraine to school shootings and COVID vaccines, TikTok’s users are consistently fed false and misleading claims,” wrote NewsGuard.
