Measuring the value that US residents place on clean water

A new special edition of the Proceedings of the National Academy of Sciences (PNAS) focuses on helping federal regulators measure the value that U.S. residents place on clean water, just months before the Supreme Court is set to decide a case with significant implications for the Clean Water Act.

Do people and monkeys see colors the same way?

New findings in color vision research imply that humans can perceive a greater range of blue tones than monkeys do. Distinct connections found in the human retina may indicate recent evolutionary adaptations for sending enhanced color vision signals from the eye to the brain.

The science behind the life and times of the Earth's salt flats

Researchers have characterized two different types of surface water in the hyperarid salars -- or salt flats -- that contain much of the world's lithium deposits. This new characterization represents a leap forward in understanding how water moves through such basins, and will be key to minimizing the environmental impact on such sensitive, critical habitats.

The science behind the life and times of the Earth's salt flats

Researchers at the University of Massachusetts Amherst and the University of Alaska Anchorage are the first to characterize two different types of surface water in the hyperarid salars—or salt flats—that contain much of the world's lithium deposits. This new characterization represents a leap forward in understanding how water moves through such basins, and will be key to minimizing the...

Thrift shops thrive when disorder is balanced with high seller knowledge

One person's trash may well be another's "come up," or what the rapper Macklemore calls hidden treasures in the song "Thrift Shop," but only if secondhand shoppers follow the rapper's lead and dig through what are sometimes messy bins. New research from Penn State and Texas Christian University shows that shoppers looking to "pop some tags" may be drawn to disordered thrift shop displays because...

Interactive 3D model recreates Old Man of the Mountain

Twenty years after the Old Man of the Mountain collapsed, audiences around the world will now be able to explore the iconic symbol of New Hampshire through an online interactive 3D model created by Matthew Maclay, a graduate student in earth sciences at Dartmouth's Guarini School of Graduate and Advanced Studies.

New 50-year study offers insight into effects of climate on bird reproduction

A new study reported in the Proceedings of the National Academy of Sciences has assessed changes in the reproductive output of 104 bird species around the world between 1970 and 2019. The study reveals that a warming climate appears to have more worrisome effects on larger birds and migratory birds than on smaller, sedentary species.

People in comas showed ‘conscious-like’ brain activity as they died, study says

‘Potential neuro-signatures of consciousness’ observed in unresponsive patients at time of death, scientists saySome recall bright lights at the end of a tunnel, feeling the presence of loved ones or floating above their body after a near-death experience. Now, scientists say they have captured “conscious-like” brain activity in dying patients in findings that give new insights into the...
