Implementation of school-based well-being programs benefits from multiple voices, says study
Health and well-being education can be an important addition to a school curriculum. But for these programs to be effective, they must be delivered in a way that works for everyone, including students, instructors, and school administrators. A new study from University of Illinois evaluates the implementation of two prevention programs, using a mixed-methods approach with input from multiple...
Study finds neighborhood apps increase perceptions of crime rates
How often do you glance at your neighborhood app, like Nextdoor or others, and learn about some crime in your area? Surely, it was not the intention of the app developers, but every time you hear of a crime nearby, you might think that crime in your area is rampant. A new study by a University of Houston psychologist indicates that is exactly how the mind works—those helpful and popular...
Exploring bonds and electronic structure in plutonium hybrid materials
Understanding the arrangement of electrons in compounds containing actinide elements, such as uranium and plutonium, can help advance the design of next-generation nuclear materials. These elements are challenging to study due to their complex chemistry and radioactivity. Additionally, these elements, which are in a sequence of related elements called the actinide series, have electrons that are...
Vancouver Park Board asking residents to report Canada geese nests to help with population control
Board staff are asking for help locating nests in order to swap the eggs out for ones that will not hatch in an effort to control a growing population that is wreaking havoc in public...
In the tropics, woody vines may make lightning more deadly for forests
Many tropical forests are experiencing increases in lightning and lianas, thanks in part to global change. This one-two punch is likely causing an increase in the death of small trees, which could lead to shifts in composition of tropical forests and their ability to store carbon. A paper in the journal New Phytologist reports on this development.
The organization of sex trafficking: Study reveals entrepreneurial cycle of human exploitation
Through coercion and deception, more than 20 million people around the world are forced into labor that generates more than $150 billion in annual profits, according to the International Labour Organization (ILO).
New research highlights an overlooked accelerant of ice loss from Antarctica's Thwaites Glacier
In West Antarctica, the 80-mile-wide stream of sliding ice at the heart of Thwaites Glacier is likely to creep outward over the next 20 years, a change that could speed up ice loss, new research finds.
Advanced electrode to help remediation of stubborn new 'forever chemicals'
As new environmental regulations are rolling out to mitigate the industry-retired long-chain chemicals known as PFAS in drinking water, there are concerns regarding a new breed of "forever chemicals" called short-chain PFAS. Research from the University of Illinois Urbana-Champaign is helping shift the focus to include mitigation of the chemicals—which researchers say are just as persistent as,...
Rare beetle, rediscovered after 55 years, named in honor of former governor
When University of California, Berkeley, entomologist Kipling Will first heard that former Gov. Jerry Brown was hosting field scientists on his Colusa County ranch, he jumped at the chance to hunt for beetles on the property.
JWST confirms giant planet atmospheres vary widely

Astronomers have found the atmospheric compositions of giant planets out in the galaxy do not fit our own solar system trend.
Temperature of a rocky exoplanet measured
- ScienceDaily
- 23/3/27 22:32
An international team of researchers has used NASA's James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet's thermal emission: heat energy given off in the form of infrared light detected by Webb's Mid-Infrared Instrument (MIRI). The result indicates that the planet's dayside has a temperature of about 500 kelvins (roughly...
Bomb-sniffing rodents undergo 'unusual' reproductive transformations

The community of microbes living in and on our bodies may be acting as a reservoir for antibiotic resistance, according to new research.
The Greenland Ice Sheet is close to a melting point of no return
- ScienceDaily
- 23/3/27 22:32
A new study using simulations identified two tipping points for the Greenland Ice Sheet: releasing 1000 gigatons of carbon into the atmosphere will cause the southern portion of the ice sheet to melt; about 2500 gigatons of carbon means permanent loss of nearly the entire ice sheet. Having emitted about 500 gigatons of carbon, we're about halfway to the first tipping point.
Strong winds drive early Spain wildfire
Strong winds fanned the flames of Spain's first major fire of the year on Monday, complicating work for firefighters despite milder temperatures.
Study suggests pumas utilize sly strategy of fertilizing plants that recruit prey to hunting grounds
A new Panthera study published today in Landscape Ecology has found that pumas might utilize a sly hunting strategy known as 'garden to hunt,' by which puma kills fertilize or deposit nutrients in soil that increase plant quality and attract ungulates to feed in select habitat conducive to future stalk-and-ambush puma hunting.
HIV can persist for years in myeloid cells of people on antiretroviral therapy
A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health.
Vehicle exhaust filters do not remove 'ultrafine' pollution, according to new study
Filters fitted to vehicle exhaust systems to remove particulate matter pollution have limited impact on ultrafine particles, new research shows.
The Greenland Ice Sheet is close to a melting point of no return, says new study
The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren't sure how quickly the ice sheet could melt. Modeling tipping points, which are critical thresholds where a system behavior irreversibly changes, helps researchers find out when that melt might occur.
Beneficial bacteria in the infant gut uses nitrogen from breast milk to support baby's health

A nutrition scientist who has spent his career studying breast milk has demonstrated how beneficial microbes in the gut of infants use nitrogen from human milk to support pediatric nutrition and development.
Home gardens are key to better lives for vulnerable tribes in India, finds research
The forested hills and rolling fields in the state of Odisha are home to some of India's most vulnerable tribal groups, but a growing number of studies show that small home gardens—producing millet, pulses, fresh fruits and vegetables—could be key in the fight against the food insecurity, malnutrition and poverty found there.
A machine learning framework to predict and quantify synthesis difficulties for designer chromosomes
Artificially synthesizing genomes has broad prospects in fields such as medical research and developing industrial strains. From the synthesis of the artificial life JCVI-syn1.0 by Craig Venter's team in 2010, to the rewriting and synthesis of the prokaryotic E. coli genome, and to the Sc2.0 project's artificial synthesis of the yeast genome, researchers are constantly advancing in the depth and...
