Credit: Unsplash/CC0 Public Domain A high-sugar diet is bad news for humans, leading to diabetes, obesity and even cancer. Yet fruit bats survive and even thrive by eating up to twice their body weight in sugary fruit every day. Now, UC San Francisco scientists have discovered how fruit bats may have evolved to consume so … Read more
by KeAi Communications Co. Credit: Peishan Shao, et al Mechanoluminescence (ML) located within the near infrared (NIR) spectral range may hold promising applications in in-situ and real-time biomechanical imaging. This is due to the better spatial resolution and penetration depth of the biological tissues, lower optical loss, and the avoidance of autofluorescence. Historically, rare earth … Read more

CHARA Array false-color images of RW Cephei from December 2022 (left) and Jul 2023 (right). The patchy appearance results from dust created by a huge ejection from the star. The star is huge but it is so far away that it appears about one million times smaller than the full moon in the sky. Credit: … Read more
In each water sample, researchers examined nitrate isotopes, which are unique, allowing the team to trace the water sample back to where it originated. Credit: University of Texas at Arlington Four decades of changes in land use in central Costa Rica have increased nitrate concentrations in drinking water, in some areas to potentially unsafe levels, … Read more
