Archaeologists surveying a bus station in Exeter, England, have unearthed traces of a military fort dating to the Roman occupation of Britain, the local city council announced this week. Per a press release, workers excavating the structure—built during the early 1960s and scheduled to be replaced by a new station and accompanying leisure complex—found three

  Vikram had a “hard landing”, the National Aeronautics and Space Administration (NASA) said on Friday, as it released high-resolution images captured by its reconnaissance orbiter of the Moon’s unchartered south pole where the Chandrayaan 2 lander attempted to soft-land during the ambitious mission three weeks ago. The module had attempted a soft landing on

The complex interplay among the arteriovenous grafts, the vessels they connect, and the blood they transport has been difficult to simulate, but one new method provides a way. Researchers report simulations that reconstructed the fluid dynamics affected by the insertion of an AVG. They used a model that considered the ability of AVG tubes and

Valda Harris Montgomery can still remember the Freedom Riders staying at her childhood home. It was May 1961, and the group of African-American activists had ridden into a segregated bus station in Montgomery, Alabama—a direct challenge to racist policies in the South. They were harassed and attacked, and eventually transported by the National Guard to

It’s common knowledge that, through the process of natural selection, organisms adapt to their environments. But what happens when there are no barriers to gene flow and organisms are free-floating between extremely variable environmental conditions? A new study by UConn researchers seeks to tease out some of the myriad pressures that drive adaptation in small,
