The Source of the Irish Potato Famine Pathogen Is Finally Identified

Posted on Categories Discover Magazine

A genetic investigation has finally tracked down the source of the pathogen that caused the Irish potato famine, closing a case that has been up in the air for years. Researchers nailed down the Andes Mountains in South America as the birthplace of Phtytophthora infestans, otherwise known as potato blight or late blight. The pathogen, taking the form of a fungus-like microorganism (oomycete/water mold), has devastated potato and tomato plants throughout history. A new study published in the jou ...read more

Adults with ADHD May Have Shorter Life Expectancy Than Those Without

Posted on Categories Discover Magazine

According to a new U.K. study published in The British Journal of Psychiatry, adults diagnosed with attention deficit hyperactivity disorder (ADHD) may have shorter life spans than those without. In this first-of-its-kind study, the authors determined that both men and women saw a drop in life expectancy, and this may be due to limited access to treatments and an overall misdiagnosis of ADHD.   A Shortened Life Expectancy Researchers from the University College London (UCL) analyzed data fro ...read more

Our Understanding of Rules that Produce Life’s Genetic Code May Require a Revision

Posted on Categories Discover Magazine

“Get me a rewrite,” reporters used to shout into a telephone when they called into a newsroom with changing information. Scientists may now want to yell the same thing — but about how our existing genetic code came to be, according to a study in PNAS. That rewrite could shift our understanding of how life evolved on Earth from its simplest forms, and what it could look like on other planets.How the Genetic Code WorksThat code is both deceptively simple in appearance, but amazingly complica ...read more

Romanian Animal Fossils Reveal Hominin Spread Into Europe 2 Million Years Ago

Posted on Categories Discover Magazine

In the relentless search to know how the ancestors of humans spread across the world, the latest evidence has revealed that hominins were in Europe at least 1.95 million years ago. Clues on their presence were recently found by researchers at an archaeological site in Romania that could now help explain hominins’ early dispersal out of Africa.A study published in Nature Communications details the prominent find, which predates evidence of hominins previously found at other sites across Europe ...read more
