Special wildlife exits on busy roads help protect endangered ocelots
The Texas ocelot (Leopardus pardalis albescens) is endangered due to historic hunting, habitat loss, inbreeding, and traffic collisions. Today, only between 50 and 80 ocelots remain in the U.S., exclusively in Willacy and Cameron counties in southern.....»»
Galactic archaeology uncovers the dramatic history of our next-door neighbor, the Andromeda galaxy
Research led by the University of Hertfordshire has revealed the dramatic history of Andromeda, our nearest neighboring galaxy. Using state-of-the-art modeling, Professor Chiaki Kobayashi and a team of international astrophysicists have determined de.....»»
Models suggest interlinking rivers in India to meet water demand may adversely impact monsoon rainfall amounts
A team of civil engineers and meteorologists at the Indian Institute of Technology, working with colleagues from the Indian Institute of Tropical Meteorology and the University of Hyderabad, has found, via modeling, that a plan to interlink rivers in.....»»

Exploring stellar hydrogen burning via muons and nuclei
The muon is a subatomic particle that resembles an electron but is 200 times heavier. It interacts with nuclei through the weak force, one of the four fundamental forces in the universe. When a muon binds with a deuteron (composed of one proton and o.....»»
Model of photosynthetic antenna suggests different types of plants may grow on Earth-like rocky planets
A small team of biologists, environmental scientists and chemists at Queen Mary University of London, U.K., has found via modeling, that it might be possible for different types of plants to grow on Earth-like rocky planets. In their paper published.....»»
Ascertaining distances for supernovae that struck the Earth 3 million and 7 million years ago
A study, released on the pre-print server arXiv, examines how the Earth was hit by blasts from supernovae (plural form of supernova (SN)) that occurred 3 million years ago (Mya) and 7 Mya with the goal of ascertaining the distances of where these bla.....»»
Observations explore the properties of Type Ic supernova SN 2022jli
