Philly's snowpack reaches a 65-year milestone, and here's when it finally may disappear‎

You may not have noticed, but that endless snowpack has developed a slow leak—in this case, historically slow. Its endurance continues to climb the charts among the snowpacks of yesteryear—and in at least one way may well be unprecedented in the period of record dating to the late 19th century.

Incentive program for teachers yields long-term student gains‎

A teacher-incentive program in South Carolina has led to striking long-term benefits for students, including lower rates of felony arrest and reduced reliance on government assistance in early adulthood, according to a new study published in the Journal of Public Economics. Ozkan Eren, a professor of economics at UC Riverside, co-authored the study with colleagues at the University of Michigan and University of South Carolina.

Key species threats in Costa Rica mapped using new metric‎

New research has revealed the biggest threats driving species toward extinction in northern San José, Costa Rica. Led by Newcastle University, the study found that the greatest potential to reduce species extinction risk in the Northern Sub-catchments of San José, Costa Rica, lies in addressing habitat loss and degradation due to livestock farming and ranching, urban expansion, and the spread of non-native invasive species.

3D scanning and shape analysis help archaeologists connect objects across space and time to recover their lost histories‎

Today the world of Egyptology faces a silent crisis—not of looting, although that plays a part, but of disconnection. Walk into any major museum, from Copenhagen to California, and you see glass cases filled with what could be called orphaned artifacts: remarkable objects, often acquired in the 19th and early 20th century, that have been completely stripped of their histories. You can see what they are—a mummy's painted foot case, a golden mask—but we have no idea where they came from. They are beautiful, but historically they are mute.

New national study reveals 'mixed legacy' of pandemic on early childhood development‎

New research led by Professor Claudine Bowyer-Crane has uncovered a complex picture of how COVID-19 reshaped the lives of young learners in England. The ICICLES study was initiated while Professor Bower-Crane was at the National Institute of Economic and Social Research (NIESR). The study tracked children's language, socioemotional, and educational progress for three years following the initial lockdowns. While many children displayed remarkable personal resilience, national data suggests a troubling "lost ground" in core academic skills, particularly writing.

New remote sensing model maps 2021 frost damage across 700,000 hectares of corn‎

Brazilian researchers have developed a methodology that uses remote sensing to map the impact of frost on corn crops. This reduces exposure to climate risks and uncertainty regarding agricultural losses.

Youth build resilience in climate-vulnerable Sierra Leone‎

Beginning two summers ago in a building lacking reliable power and internet, dozens of teenagers in Bo City, Sierra Leone watched videos about climate science, then discussed opportunities to build resilience in one of the world's most climate-vulnerable nations. The Community Youth Climate Science Lab and Collaboration Hub—founded by a Cornell expert and an alumnus of the U.S. Department of State's Mandela Washington Fellowship for Young African Leaders—has since helped plant 1,500 shade trees, built raised-bed gardens and cultivated a network of future leaders invested in climate adaptation in their hometown, Sierra Leone's second-largest city.

Why relationship confidence matters: Study links it to mental health, sleep, substance use‎

When couples attend relationship counseling, it benefits not only their partnership but also their individual well-being. But which aspects of the training are most influential in this respect? A new study from the University of Illinois Urbana-Champaign published in the Journal of Marital and Family Therapy examines how a popular intervention program affected individual outcomes such as mental health, sleep, and substance use.

How forest conversion can harm dung beetles‎

Researchers at the University of Würzburg have shown that dung beetles suffer in canopy openings that have been deliberately created to promote biodiversity. Rising temperatures are significantly exacerbating the problem.

Isotopes reveal how social status shaped diet in medieval England‎

Isotope analysis reveals that social status and wealth had a profound impact on diet in medieval England, showing that people from different social groups in medieval Cambridge ate markedly different food. The research, carried out as part of the "After the Plague" project at the University of Cambridge and published in the journal Antiquity, analyzed carbon and nitrogen isotopes preserved in bone collagen from individuals buried in Cambridge between the 10th and 16th centuries AD.
