Research involving human embryos is famously difficult and fraught with ethical quandaries, but a new synthetically derived model could open new doors in the study of infertility and birth defects.The model comes from the Weizmann Institute of Science in Israel and follows years of research by labs around the world into producing a similar clump of cells. The team led by professor Jacob Hanna claims that their latest iteration is the most advanced so far and contains all the hallmarks of a human ...read more
Alzheimer’s takes a toll on its patients. As the disease progresses, a person’s personality deteriorates, and so, too, does their judgement, their memory, and their motor skills. But a diagnosis of Alzheimer’s dementia affects much more than the individual who is diagnosed. That’s because the disease fosters feelings of fear and loss for the family, friends, and loved ones who witness its destruction, while also causing concerns for those same individuals about their own futures with the ...read more
The James Webb Space Telescope (JWST) has brought us marvelous images of whirlpool galaxies, supernovas and even questionable space phenomena. But building and getting the device operational was an incredible feat of science, involving hundreds of people from all around the world and three space agencies.What Is the James Webb Space Telescope? The telescope isn’t on this planet — it orbits the sun. The JWST was launched on December 25, 2021, at 7:20 a.m. EST. In total, it weighs more than 1 ...read more
In 1914, the biggest story in newspapers across the U.S. was the world war that had recently broken out in Europe with a big question mark hanging over whether the U.S. would take part. The same story dominated the U.S. newspapers in 1915, 1917 and 1918. But in 1916, another story captured the attention of the American public, one that is much less well known today.In that year, the U.S. Army entered Mexico in pursuit of a Mexican paramilitary force that had attacked the town of Columbus in New ...read more
In recent years, scientists have puzzled over a particular class of transients – bursts of intense X-rays and light shot from distant galactic centers. Now, astronomers have discovered a new X-ray transient and are offering an explanation for these outbursts. The new find – located at the center of a galaxy some 500 million light-years away – is early fruit for a new transient detection system that feeds off data produced by the Swift Observatory X-ray telescope.What Are Transients?Astrono ...read more
