As human cases of flea-borne murine typhus continue to occur in South Texas, researchers are working to better understand the role cats and their fleas may play in the disease's transmission cycle.
Phys.org / Single-atom catalyst turns lignin into valuable chemicals with near-complete conversion
Researchers at The University of Manchester and Hebei University of Technology have identified how a new class of catalyst can break down lignin into useful chemical building blocks, offering a more sustainable route to replace ...
Phys.org / Modern life may be outpacing the human mind
The human brain evolved for a world of familiar faces, immediate threats and small social groups. But the world around us is changing far faster than human biology can keep pace. That mismatch may help explain some of the ...

Hidden beneath the water's surface is a botanical world that is among nature's most innovative and ecologically important.
Phys.org / XMM-Newton and Chandra help revise distance to Milky Way's outer spiral arms
The European Space Agency's XMM-Newton and NASA's Chandra X-ray space telescopes have spotted the aftermath of three bright explosions echoing through the outer spiral arms of our galaxy, the Milky Way. By measuring the distance ...
Phys.org / Beyond the dust: Families describe daily health challenges near the Salton Sea
A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children ...
Phys.org / Harsh UVB bursts leave tadpoles with more DNA damage than longer exposure
Sunburn is a serious problem in the Southern Hemisphere, where depleted ozone provides less protection from UVB. Tadpoles are at particular risk because they are growing rapidly, making them vulnerable to UVB DNA damage. ...
Phys.org / Earliest Americans specialized in megafauna hunting from Alaska to South America, analysis of 50 sites reveals
New research led by a University of Alaska Fairbanks archaeologist reveals that the earliest Native Americans had highly specialized diets, primarily hunting the largest animals on the landscape, and they targeted these megafauna ...
Phys.org / This satellite constellation transformed earth science by creatively tuning in to GPS signals
When NASA's Cyclone Global Navigation Satellite System, or CYGNSS, launched into orbit in 2016, none of the University of Michigan Engineering researchers who developed the system expected it to transform earth science. They ...
Medical Xpress / A blood protein can flag dementia risk decades before symptoms appear
Forgetting the name of a loved one may be one of the first signs people notice of dementia, but it's rarely the first warning sign your brain gives. Changes in the brain that lead to neurodegenerative diseases like Alzheimer's ...
Phys.org / Hantaviruses may have co-evolved with rodents for ages, helping explain silent spread
What does a hantavirus do inside its rodent hosts? How do these viruses move through animal populations? And how is it that they cause almost no apparent symptoms in rodents, yet can be nearly fatal in humans? Specially Appointed ...
Phys.org / Walkable, greener neighborhoods linked to better physical and mental health across the U.S.
A new big-data analysis of the U.S. pinpoints how urban design aids the health of city residents—especially when cities provide walking opportunities, greenery and mixed-use streets with a blend of commercial and residential ...
