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.
A potential therapeutic approach for treating colistin-resistant infections
Colistin is a last-resort antibiotic critical for treating multidrug-resistant bacterial infections. Resistance to colistin heralds the emergence of truly pan-resistant infections.
Why does your life flash before your eyes near death?
Survivors of close calls with death often recall extraordinary experiences: seeing light at the end of a tunnel, floating outside their own bodies, encountering deceased loved ones or recapping major life events in an instant.
Environmental groups sue FAA over SpaceX Texas rocket launch
Wildlife and environmental groups sued the Federal Aviation Administration on Monday over SpaceX's launch last month of its giant rocket from Texas.
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...
Scientists describe carbon cycle in a subglacial freshwater lake in Antarctica for first time
Subglacial lakes that never see the light of day are among the least accessible frontiers of science, brimming with more tales yet untold than even the planets of our solar system. One thing seems certain: where there is water, there is life—even if said water is at the bottom of a frigid lake, in pitch darkness, below more than a half mile of the West Antarctic Ice Sheet.
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...
Magnetic imaging unlocks crucial property of 2D superconductor
Using state-of-the-art magnetic imaging, a Cornell-led collaboration has for the first time characterized a key property of the superconducting state of a class of atomically thin materials that are too difficult to measure due to their minuscule size.
Scientists use ultrabright X-ray beams to characterize broadly neutralizing antibodies against a range of coronaviruses
New variants of the coronavirus that caused the COVID-19 pandemic continue to emerge. To combat them, researchers are doing everything they can to find new therapies that can target a broad range of different coronavirus strains.
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.
Food, fertilizer, fuel? Hunt is on for solutions to Caribbean's exploding seaweed problem
Most of the troubles plaguing the subtropical waters of Florida and the Caribbean revolve around disappearing marine life: coral reefs, fish populations, sea grass beds. It's decidedly the opposite case with sargassum, the floating brown seaweed that has exploded in record-setting mass throughout the region.
Study: Police murder of George Floyd associated with short-term spike in firearm assaults on US police officers
The police murder of George Floyd sparked nationwide protests in the summer of 2020 and revived claims that public outcry over such high-profile police killings perpetuates a violent "war on cops." In a new study, researchers assessed if and how patterns of firearm assault on police officers in the United States were influenced by the police murder of Floyd.
What to know about red-flag warnings, an ominous wildfire forecast
The northeast U.S. is no stranger to extreme weather and the warnings that come with it. But every now and then, residents are faced with an unfamiliar color in the forecast: red.
Epic snowpack upends rhythms of life for many species in Sierra Nevada range
The Big Melt is finally underway in the Sierra Nevada range, and soon there will be few wild places beyond the reach of water sounds: dripping, gurgling and roaring as runoff flows from lofty peaks to sage plains below.
Bacteria could make salmon healthier
Researchers, including from NTNU, are breeding bacteria-free fish fry. This pursuit is more important than you might think.
Massive radio array to search for extraterrestrial signals from other civilizations
One of the world's most powerful radio telescope arrays is joining the hunt for signals from other galactic civilizations. The National Science Foundation's Karl G. Jansky Very Large Array (VLA), situated about 50 miles west of Socorro, New Mexico, is collecting data that scientists will analyze for the type of emissions that only artificial transmitters make, signals that would betray the...
Researchers pin down PFAS prevalence in firefighter gear
A firefighter's protective clothing, called turnout gear, is essential for operating in the dangerous conditions of a fire. However, the firefighting community has raised concerns regarding the presence of a class of chemicals called per- and polyfluoroalkyl substances (PFAS)—some of which have been linked to cancer—in the gear.
Drones offer more efficient way to survey vital oyster reefs
Skimming 100 feet above the Gulf waters at 13 miles per hour and blasting out 700,000 laser pulses every second, a drone flies over this oyster reef off the Big Bend coast of western Florida in early 2021. A few minutes later, the drone lands on shore and, with a little computer magic back at the lab, spits out what the drone operators want to know: How are these reefs doing?
Scientists use power of AI to supercharge planetary studies
A new technique for detecting planetary craters that will allow scientists to accurately map the surfaces of planets using different types of data could be used in future space missions.
Examining the nuances of the forest-water connection
The infrastructure that brings drinking water to homes is an investment. For millions of people, forests are part of the system behind their faucets. Over the coming decades, many forested watersheds could be lost to development, lowering water quality and raising water treatment costs, according to a new study published in the journal Science of the Total Environment.
Upcycling method turns textile trash to functional coatings
In an effort to make textiles more sustainable, a new method allows researchers to break old clothing down chemically and reuse polyester compounds to create fire resistant, anti-bacterial or wrinkle-free coatings that could then be applied to clothes and fabrics.
SpaceX Starship effectively grounded by FAA after in-flight explosion
It was an exciting time when, two weeks ago, SpaceX got the clearance it needed to conduct its first orbital flight test with the Starship and Super Heavy launch system. After years of waiting, SN flight tests, static fire tests, and stacking and unstacking, the long-awaited test of the SN24 Starship and BN7 Booster prototype was on. For this flight, SpaceX hoped to achieve an altitude of at least...
JWST's MIRI instrument is having problems again
Last week, NASA shared a blog post saying they detected a sensor glitch associated with the James Webb Space Telescope's Mid-Infrared Instrument (MIRI). For some reason, the sensor for MIRI's Medium Resolution Spectroscopy (MRS) is receiving less light than expected at the longest wavelengths.
Isotope analysis helps tell the stories of Aboriginal people living under early colonial expansion
In 2015, Gkuthaarn and Kukatj community members of Queensland's Gulf Country invited us to excavate, analyze, and rebury the skeletal remains of eight young Indigenous people who died near the town of Normanton in the late 1800s.
