As climate change alters the temperatures of animal habitats, it seems natural that endotherms, warm-blooded animals, would prefer to hang out in the shade during hot weather. The use of microhabitats in the sun and shade is an important thermoregulatory behavior that has been reported across a wide range of animal species, and researchers are becoming increasingly interested in how animals—especially those with long lifespans—flexibly cope with thermal stress.

A sonic boom shook Boston and the larger New England area with the force of 230 tons of TNT. The source came from outer space. The Saturday afternoon event triggered shock waves online, with thousands inquiring what could have caused houses to shake and a sound heard as far away as New Hampshire and Rhode Island.

University of Florida researchers are exploring how lasers could help astronauts build structures on the moon using materials already available there, including lunar soil transformed into glass. The work, led by Victoria M. Miller, Ph.D., an associate professor in the Herbert Wertheim College of Engineering and researcher with the UF Astraeus Space Institute, recently completed a research phase focused on laser forming, a manufacturing process that bends materials without physical contact.

In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a vast ocean once covered the landing site.

SpaceX, the rockets-to-AI behemoth led by Elon Musk, aims to raise $75 billion in the biggest initial share sale ever, as the world’s richest person pursues data centers in space and a trip to Mars.

SpaceX says it plans to raise up to $75 billion when it goes public this month, setting the stage for the largest-ever stock market debut and putting Elon Musk on course to becoming the world’s first trillionaire.

Austin Zwick, associate teaching professor in the College of Professional Studies and the Maxwell School of Citizenship and Public Affairs, explains how cities can fix their planning systems to address housing crises.

A research team led by Professor Shuichi Hiraoka at the University of Tokyo and Professor Masanori Tachikawa at Yokohama City University has quantitatively analyzed how molecules pass through dynamic nanoscale pores using self-assembled molecular “nanocubes” in water. The researchers discovered an unexpected phenomenon: For linear alkane molecules, longer molecules passed through the molecular gates faster than shorter ones.
