Technology News ,World :- Scientists have unveiled a groundbreaking method to combat cancer by harnessing the power of molecular jackhammers. Researchers from Rice University, Texas A&M University, and the University of Texas discovered that stimulating aminocyanine molecules with near-infrared light causes them to vibrate in unison, effectively rupturing the membranes of cancer cells.Aminocyanine molecules, commonly employed in bioimaging as synthetic dyes, have proven stability in water and are adept at binding to the exteriors of cells. In a significant advancement over previous cancer-killing molecular machines, such as Feringa-type motors, these molecular jackhammers exhibit mechanical motion over one million times faster and can be activated with near-infrared light instead of visible light, according to chemist James Tour from Rice University.The utilization of near-infrared light is pivotal as it facilitates deeper penetration into the body, potentially allowing the treatment of cancer in bones and organs without resorting to surgery. In experiments on cultured cancer cells, the molecular jackhammer approach achieved an impressive 99 percent success rate in destroying the cells. Furthermore, tests on mice with melanoma tumors resulted in half of the animals becoming cancer-free.The unique structure and chemical properties of aminocyanine molecules enable them to synchronize with the right stimulus, such as near-infrared light. When set in motion, the electrons within these molecules generate plasmons—collectively vibrating entities driving movement across the entire molecule.Chemist Ciceron Ayala-Orozco from Rice University emphasizes the significance of this discovery, highlighting that its the first instance of a molecular plasmon being utilized to excite the entire molecule and produce mechanical action to dismantle cancer cell membranes.The plasmons, equipped with an arm on one side, establish connections between the molecules and cancer cell membranes. The ensuing vibrations then contribute to breaking apart the membranes. While the research is still in its early stages, these initial findings hold great promise.The simplicity of this biomechanical technique also makes it challenging for cancer cells to develop effective defenses. Moving forward, researchers are exploring other types of molecules that can be employed in a similar fashion. In essence, this study represents a groundbreaking approach to cancer treatment, employing mechanical forces at the molecular scale to combat the disease.

Space News ,China :- China added two new satellites to its Beidou positioning and navigation system in a recent launch, enhancing the capabilities of the Beidou-3 system. The successful launch involved a Long March 3B rocket with a Yuanzheng-1 upper stage, deploying the satellites into medium Earth orbit (MEO) at 21,532 by 22,193-kilometer orbits inclined by 55 degrees.Developed by the China Academy of Space Technology (CAST) under CASC, these satellites serve as backups, reducing operational risks to the Beidou-3 system, as stated by a CASC announcement. Notably, these are the 57th and 58th Beidou satellites launched to date.Despite the success of the satellite launch, a noteworthy incident occurred during the mission. The booster stages from the Long March 3B rocket were reported to have fallen near inhabited areas in Guangxi, downrange of the Xichang launch site in Sichuan province. Videos on Chinese social media depicted boosters falling within a forested area, with apparent explosions and wreckage near homes.The presence of reddish-brown gas indicative of nitrogen tetroxide and yellowish gas possibly resulting from unsymmetrical dimethylhydrazine (UDMH) fuel mixing with air was observed in the footage. Both the nitrogen tetroxide oxidizer and UDMH fuel pose serious health risks.This incident is not an isolated case, as previous Beidou satellite launches have also witnessed boosters falling near populated areas. China choice of deep inland launch sites, established during the Cold War for strategic reasons, leads to booster stages falling on land rather than in oceans, as seen in U.S. and European launches.While authorities reportedly issue warnings and evacuation notices to mitigate the risks associated with falling debris, the China Aerospace Science and Technology Corporation (CASC) has been experimenting with technologies like grid fins, parafoils, and parachutes to limit drop zones.China orbital launch endeavors in 2023 have set a new national record, with this Beidou launch being the 65th of the year. Despite the absence of launch failures, CASC fell short of its goal of over 60 launches, with commercial space actors contributing 16 launches to the total.The Beidou satellite launch followed other recent missions, including the deployment of Tianmu-1 meteorological satellites and Shiyan-24C experimental satellites. As China continues its space exploration efforts, further launches are anticipated in the closing days of 2023.
