Sep 14, 2023 (Nanowerk News) The fact that humans and other living organisms can develop and grow from a single cell relies on a process called embryonic development. For healthy tissue to form, cells in the embryo have to organize themselves in the right way in the right place at...
Webb confirms accuracy of universe’s expansion rate measured by Hubble, deepens mystery of Hubble constant tension
Sep 14, 2023 (Nanowerk News) The rate at which the universe is expanding, known as the Hubble constant, is one of the fundamental parameters for understanding the evolution and ultimate fate of the cosmos. However, a persistent difference called the “Hubble Tension” is seen between the value of the constant...
Electrons from Earth may be forming water on the Moon
Sep 14, 2023 (Nanowerk News) A team of researchers, led by a University of Hawai‘i (UH) at Mānoa planetary scientist, discovered that high energy electrons in Earth’s plasma sheet are contributing to weathering processes on the Moon's surface and, importantly, the electrons may have aided the formation of water on...

Enhancing atherosclerosis diagnosis using ultrasmall calcium carbonate nanoparticles
Sep 14, 2023 (Nanowerk News) Atherosclerosis is characterized by the hardening of blood vessels, especially certain arteries, due to the local buildup of fibers and lipids (mainly cholesterol) in the inner wall of an artery, causing it to narrow. It is a complex disease that can trigger life-threatening events, such...
Scientists design artificial ‘stalactite’ nanopores that mimic natural structures
Sep 14, 2023 (Nanowerk Spotlight) Nanopores are emerging as a powerful platform technology with applications across biosensing, energy harvesting, and other fields. However, most existing solid-state nanopore designs face challenges like instability, difficulties tuning the size, and inadequate ion selectivity. Scientists have been searching for ways to create more versatile...
