An impressive operation recently took place in CERN’s magnet test hall. The innovative cold powering system has been successfully installed in the High-Luminosity LHC (HL-LHC) Inner Triplet (IT) String test stand. This novel system comprises a long electrical transmission line, which has been specially developed to transport currents to the magnets across a wide range of temperatures. Its installation in the IT String follows on from the installation of the novel protection system and is an important milestone in the development of the HL-LHC.

The High Luminosity LHC (HL-LHC) is a major upgrade of CERN’s Large Hadron Collider (LHC), which aims to increase the number of particle collisions (luminosity) and consequently boost the amount of physics data that can be collected, allowing further discoveries to be made.

Innovative beam-focusing magnets, known as inner triplets, are a major part of this upgrade. These magnets will be deployed on both sides of the beam interaction points at the ATLAS and CMS experiments with new powering, protection and alignment systems and – just like the LHC magnets – they will operate at 1.9 K (an extremely cold temperature, colder than deep outer space).

NASA’s Curiosity rover is preparing for the next leg of its journey, a months-long trek to a formation called the boxwork, a set of weblike patterns on Mars’s surface that stretches for miles. It will soon leave behind Gediz Vallis channel, an area wrapped in mystery. How the channel formed so late during a transition to a drier climate is one big question for the science team. Another mystery is the field of white sulfur stones the rover discovered over the summer.

Curiosity imaged the stones, along with features from inside the channel, in a 360-degree panorama before driving up to the western edge of the channel at the end of September.

The rover is searching for evidence that ancient Mars had the right ingredients to support microbial life, if any formed billions of years ago, when the Red Planet held lakes and rivers. Located in the foothills of Mount Sharp, a 3-mile-tall (5-kilometer-tall) mountain, Gediz Vallis channel may help tell a related story: what the area was like as water was disappearing on Mars. Although older layers on the mountain had already formed in a dry climate, the channel suggests that water occasionally coursed through the area as the climate was changing.

We can expect to see more recommendations for VR in catastrophic injury cases.

Immersive Virtual Reality (IVR or VR) as a tool in rehabilitation is changing at pace and has far reaching consequences that will increasingly be seen in the claims space.

Combined with AI powered treatment planning and smart home devices for daily rehabilitation, innovative technologies are now evident in all aspects of rehabilitation.

The orbits of the planets around the Sun have been the source for many a scientific debate. Their current orbital properties are well understood but the planetary orbits have evolved and changed since the formation of the Solar System.

Planetary migrations have been the most prominent idea of recent decades suggesting that planetary interactions caused the young planets to migrate inwards or outwards from their original positions.

Now a new theory suggests a 2–50 Jupiter-mass object passing through the Solar System could be the cause.

Yongcui Mi has developed a new technology that enables real-time shaping and control of laser beams for laser welding and directed energy deposition using laser and wire. The innovation is based on the same mirror technology used in advanced telescopes for astronomy.

In a few years, this new technology could lead to more efficient and reliable ways of using lasers for welding and directed energy deposition with laser and wire. The manufacturing industry could benefit from new opportunities to build more robust processes that meet stringent quality standards.

“We are the first to use deformable technology for this application. The mirror optics can handle multi-kilowatt laser power, and with the help of computer vision and AI, the laser beam can be shaped in real time to adapt to variations in joint gaps,” explains Yongcui, a newly minted Ph.D. in Production technology from University West.

What processes are responsible for dust storms on Mars? This is what a study presented today at the American Geophysical Union 2024 Fall Meeting hopes to address as a pair of researchers from the University of Colorado Boulder (CU Boulder) investigated the causes behind the massive dust storms on Mars, which periodically grow large enough to engulf the entire planet. This study holds the potential to help researchers predict dust storms on Mars, which could help current and future robotic missions survive these calamities, along with future human crews to the Red Planet.

“Dust storms have a significant effect on rovers and landers on Mars, not to mention what will happen during future crewed missions to Mars,” said Heshani Pieris, who is a PhD Candidate in planetary science at CU Boulder and lead author of the study. “This dust is very light and sticks to everything.”

For the study, the researchers examined 15 (Earth) years of data obtained from NASA’s Mars Reconnaissance Orbiter (MRO) to ascertain the processes responsible for kickstarting dust storms. After analyzing countless datasets of Martian surface temperatures, the researchers found that 68 percent of large dust storms on Mars resulted from spikes in surface temperatures during periods of increased sunlight through Mars’ thin atmosphere.
