If you look up into the sky over the next few months, you can see an object last seen when Neanderthals walked the Earth. On March 2, 2022, astronomers at the Zwicky Transient Facility discovered a comet using a wide-field survey camera. The comet is estimated to complete an orbit of the Sun once every 50,000 years, meaning the last time we saw the comet was in the Upper Paleolithic period, when humans began to expand throughout Asia and Europe.

Seven Of JWST’s Best Images From Its First Year In Orbit

JWST has been the star (pun intended) of this year in science, wowing the world with the beauty of its images and forming the basis of an astonishing number of abundant scientific papers, published in record time. When looking at some of the highlights, it’s important to remember it’s only been in orbit for just over a year, and in full operation for half that time. Read the full story here.


New Blood Test Could Spot Alzheimer’s Disease Without The Need For Expensive Scans

A new biomarker that can be used to spot neurodegeneration associated with Alzheimer’s disease in the blood has been identified. The discovery could one day lead to a diagnostic blood test for the disease, eliminating the need for invasive and costly procedures. Read the full story here.

Feature Of The Week: 

What Is Ockham's Razor? And Is It Ever Useful?


William of Ockham, the 14th-century Franciscan friar and Catholic theologian, probably never expected his name to become synonymous with a scientific principle lasting 800 years after his death.
