UNFCCC report validates CO2 estimated cheaply and transparently using GOSAT data
Wednesday, 22 November 2023 09:26Researchers in Japan and Mongolia have carried out the world's first instance of incorporating satellite-based CO2 emission estimates into a GHG emission report as the verification on the Second Biennial Update Report (BUR2) of Mongolia submitted to the UNFCCC on 15 November 2023, resulting in high accuracy match with actual reported values, reports a new study published online in Scientific Rep
Polarized world threatens open internet: ICANN
Wednesday, 22 November 2023 09:26After 25 years of keeping the internet strong and stable, the nonprofit ICANN - responsible for its technical infrastructure - is warning that increasingly polarized geopolitics could start cracking the foundations of the online world. "It's super important to differentiate between what countries decide to do with controlling content, as opposed to the technical infrastructure," the Intern
Innovative Spray-in-Place Liner System Revolutionizes Nuclear Plant Maintenance
Wednesday, 22 November 2023 09:26Framatome, a leader in nuclear energy solutions, recently announced a significant breakthrough in nuclear plant maintenance technology. The company has successfully completed a two-year test program for what is being hailed as the industry's first spray-in-place liner system designed for rehabilitating buried piping. This development marks a pivotal moment in addressing the long-standing challen
Unlocking Europe’s satellite navigation potential at NAVISP Industry Days

Does spaceflight increase men's risk of erectile dysfunction?
Wednesday, 22 November 2023 07:00During missions into space, astronauts are exposed to high levels of galactic cosmic radiation and weightlessness. Simulation experiments in male rats indicated that these aspects of spaceflight can negatively affect vascular tissues relevant to erectile dysfunction, even after a period of long-term recovery.
The research, which is published in The FASEB Journal, indicated that vascular alterations are induced by relatively low doses of galactic cosmic radiation and, to a lesser extent, simulated weightlessness, primarily through increases in oxidative stress. Treatment with different antioxidants could counter some of these effects.
"With manned missions to outer space planned for the coming years, this work indicates that sexual health should be closely monitored in astronauts upon their return to Earth," said corresponding author Justin D. La Favor, Ph.D., of Florida State University. "While the negative impacts of galactic cosmic radiation were long-lasting, functional improvements induced by acutely targeting the redox and nitric oxide pathways in the tissues suggest that the erectile dysfunction may be treatable."

North Korea says spy satellite launch successful
Wednesday, 22 November 2023 06:26North Korea said Wednesday it had succeeded in putting a military spy satellite in orbit after two previous failures, as the United States led its allies in condemning the launch as a "brazen violation" of UN sanctions. A rocket carrying the satellite blasted off Tuesday night from North Phyongan province and "accurately put the reconnaissance satellite 'Malligyong-1' on its orbit", state-ru

Tuesday, 21 November 2023 22:32The White House on Tuesday strongly condemned North Korea over its space launch, calling it a "brazen violation" of UN sanctions that could destabilize the region. The launch "raises tensions, and risks destabilizing the security situation in the region and beyond," National Security Council Spokesperson Adrienne Watson said in a statement. North Korean state media reported early Wednes

Tuesday, 21 November 2023 11:44A series of planned crewed lunar missions worldwide have inspired a new wave of research in growing plants on the moon to sustain life. A new study by Chinese agricultural scientists found that bacteria on Earth soil could offer a solution. Published in the journal Communications Biology in early November, the study showed that three species of bacteria could increase the amount of phospho
CAPSTONE marks one year in near rectilinear halo orbit
Tuesday, 21 November 2023 11:44Terran Orbital Corporation (NYSE: LLAP) mars the one-year milestone of the CAPSTONE mission in a lunar Near Rectilinear Halo Orbit (NRHO). CAPSTONE, designed, built, and integrated by Terran Orbital and owned by Advanced Space, has demonstrated significant achievements during its mission. CAPSTONE accomplished its primary objective within the first six months in NRHO, successfully testing
Investigating the contribution of gamma-ray blazar flares to neutrino flux
Tuesday, 21 November 2023 11:44Blazars belong to the family of active galactic nuclei called quasars. What differentiates them from quasars is that the flares ejected out of these active galactic nuclei are pointed toward the Earth. These flares contain high-energy cosmic rays which are released from the core of these galaxies as jets spanning many light years. Such cosmic rays can interact with photons to produce subatomic p
