Blood protein interacts directly with nerve cells to cause brain inflammation

Neuroinflammatory diseases, including Alzheimer’s disease and traumatic brain injury, have been linked to deposits of a tough protein known as fibrin, derived from the blood clotting factor fibrinogen. These mesh-like fibrin deposits occur outside blood vessels in the brain, contributing to the death of certain central nervous system cells (neurons) that eventually leads to impaired memory. Now for […]

Why did glacial cycles intensify a million years ago?

Something big happened to the planet about a million years ago. There was a major shift in the response of Earth’s climate system to variations in our orbit around the Sun. The shift is called the Mid-Pleistocene Transition. Before the MPT, cycles between glacial (colder) and interglacial (warmer) periods happened every 41,000 years. After the MPT, […]

Air pollution multiply healthy people’s risk of depression

A genetic predisposition for depression combined with exposure to high-particulate-matter air pollution greatly elevates the risk that healthy people will experience depression, according to a first-of-its-kind study published today in the Proceedings of the National Academies of Sciences (PNAS) from neuroscientists at the Lieber Institute for Brain Development (LIBD), on the Johns Hopkins Medical Campus, and Peking […]

New AI brings the power of natural language processing to African languages

Researchers have developed an AI model to help computers work more efficiently with a wider variety of languages. African languages have received little attention from computer scientists, so few natural language processing capabilities have been available to large swaths of the continent. The new language model, developed by researchers at the University of Waterloo’s David R. Cheriton […]

“Cold bone”: Dinosaur species lived on Greenland 214 million years ago

The two-legged dinosaur Issi saaneq lived about 214 million years ago in what is now Greenland. It was a medium-sized, long-necked herbivore and a predecessor of the sauropods, the largest land animals ever to live. It was discovered by an international team of researchers from Portugal, Denmark and Germany, including the Martin Luther University Halle-Wittenberg (MLU). The […]

A “new” account of the double helix? Nah.

It’s been a minute since someone has recounted at length, in a book, the story of the solving of the double helix structure of DNA. Matthew Cobb’s Life’s Greatest Secret, which focuses on the genetic code, does a fine job. There’s Robert Olby’s Francis Crick: Hunter of Life’s Secrets (2009). Brenda Maddox’s superb Rosalind Franklin: […]
