The universe is twice as old as current estimates suggest, according to a new study that challenges the dominant cosmological model and sheds new light on what is known as the impossible problem of the first galaxies. Our newly developed model lengthens the galaxy formation time by several billion years, making the universe 26.7 billion … Read more
Scientists say a breakthrough that could help make nuclear fusion a viable energy source could be made with a mathematical model that improves our understanding of the swirling ring-shaped disturbances known as vortex rings, according to new research. Moving vortex rings have long intrigued scientists as they carry rotating fluids or gases as they travel. … Read more
They consist of III-V QW/QD DFB lasers and SiN microring resonators. Credits: Emad Alkhazraji, Weng W. Chow, Frdric Grillot, John E. Bowers and Yating Wan Laser diodes based on Quantum Well (QW) and Quantum Dot (QD) semiconductor materials integrated with SiN microresonators show promising potential due to their high energy efficiency and compact size.

A new study suggests that the universe may be 26.7 billion years old, nearly double the widely accepted age of 13.7 billion years. The new model, which incorporates Zwicky’s tired light theory and Dirac’s evolving coupling constants, could explain the existence of small mature galaxies that formed just 300 million years after the Big Bang … Read more

IIn January 2017, I met Jiankui He, the now-infamous Chinese scientist who would go on to create the world’s first genome-edited babies. This occurred during a meeting in Berkeley, California hosted by Jennifer Doudna who, along with Emmanuelle Charpentier, was awarded the 2020 Nobel Prize in Chemistry for her work on CRISPR genome-editing technology. In … Read more
A new research study has revealed a correlation between schizophrenia and somatic copy number variant gene mutations that occur after inheritance. This marks one of the initial studies to demonstrate a link between somatic mutations and schizophrenia risk. A study a Cell genomics found a link between somatic gene mutations and schizophrenia. The researchers analyzed … Read more
Seabirds are one of the most endangered animal groups in the world. They are already grappling with multiple problems, including climate change, by-catch in fishing gear, and being eaten by invasive species such as cats and some rodents. But these birds, which breed on land and feed in the sea, are now facing another threat: … Read more
