- Fiber image transmission technology for minimally invasive endoscope developed
Optical fibers are fundamental components in modern science and technology due to their inherent advantages, providing an efficient and secure medium for applications such as internet communication and big data transmission. Compared with single-mode fibers (SMFs), multimode fibers (MMFs) can support a much larger number of guided modes (~103 to ~104), offering the attractive advantage of high-capacity information and image transportation within the diameter of a hair. This capability has positioned MMFs as a critical tool in fields such as quantum information and micro-endoscopy.
- Simulating particle creation in an expanding universe using quantum computers
A new study published in Scientific Reports simulates particle creation in an expanding universe using IBM quantum computers, demonstrating the digital quantum simulation of quantum field theory for curved spacetime (QFTCS).
- Hubble traces hidden history of Andromeda Galaxy
Though the Milky Way and Andromeda formed billions of years ago, evidence shows they have very different evolutionary histories despite sharing the same cosmological neighbourhood.

There’s a picturesque early evening scene at the start of February as the Moon passes dazzling Venus and fading Saturn.
- 18,000-year-old evidence of cultural cannibalism uncovered in Poland’s Maszycka Cave
A new study published in Scientific Reports provides evidence of cultural cannibalism among the Magdalenian communities in Maszycka Cave, Poland. Conducted by an international team of researchers at IPHES-CERCA and CSIC, the study sheds new light on the mortuary and ritual practices of prehistoric peoples, indicating that Magdalenian hunter-gatherers systematically consumed human remains around 18,000 The post 18,000-year-old evidence of cultural cannibalism uncovered in Poland’s Maszycka Cave appeared first on Archaeology News Online Magazine.
- Archaeologists uncover 1.5-million-year-old hand axes in Iraqi desert
A team of archaeologists has made a breakthrough in Iraq’s Western Desert, where seven Paleolithic sites have been discovered comprising over 850 stone tools. Led by Ella Egberts from the Vrije Universiteit Brussel (VUB), this research was undertaken in late 2024 in a pilot project investigating the geomorphological history of the region and assessing the The post Archaeologists uncover 1.5-million-year-old hand axes in Iraqi desert appeared first on Archaeology News Online Magazine.
- SpaceX launches Maxar 3 mission, high-resolution commercial satellites
Washington DC (UPI) Feb 4, 2025 SpaceX launched its Maxar 3 mission, with two high-resolution commercial satellites on board, from the Kennedy Space Center in Florida on Tuesday after Monday's launch was scrubbed. The Maxar 3 mission, which carried both WorldView Legion satellites into mid-inclination Earth orbit, lifted off from Launch Complex 39A at about 6:13 p.m. EST. "SpaceX has confirmed that it is now se
- Can ocean-floor mining oversights help us regulate space debris and mining on the Moon?
Washington DC (SPX) Feb 04, 2025 Mining ocean resources needed for electric cars and other devices is currently a hot issue of dispute. Final resolution of how or whether the seabed should be exploited is pending. Outcomes in this contentious area could create precedents that could impact decisions about mining the moon. These precedents might shape the how and why of mining the Moon and shape the future and the sustainab
