Soil stores 80 percent of carbon on earth, yet with increasing cycles of drought, that crucial reservoir is cracking and breaking down, releasing even more greenhouse gases creating an amplified feedback loop that could accelerate climate change. Read more ›

A new study challenges the prevailing view on the maternal death rate in the United States. The findings show that the rates of maternal death were stable between 1999-2002 and 2018-2021, instead of the dramatic upward trends previously reported. Additionally, the study indicates that direct obstetric causes of death declined over the last 20 years. Read more ›

Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.

Dartmouth researchers tracked more than 200 undergraduates for all four years of college to capture the most in-depth data yet on how students' self-esteem and mental health fluctuates during their years in academia. The researchers identify key populations and stressors they say administrators could target to improve student well-being. The study -- conducted from 2017 to 2022 -- also provides among the first real-time accounts of how the coronavirus pandemic... Read more ›

Researchers have conducted the first large-scale observation and modeling study of northwest Greenland's Petermann Glacier. Their findings reveal the intrusion of warm ocean water beneath the ice as the culprit in the accelerated melting it has experienced since the turn of the century, and their computer predictions indicate that potential sea level rise will be much worse than previously estimated.

New, highly stretchable sensors can monitor and transmit plant growth information without human intervention. The polymer sensors are resilient to humidity and temperature, can stretch over 400% while remaining attached to a plant as it grows and send a wireless signal to a remote monitoring location, said a chemical and biomolecular engineering professor.

A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.

Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.

An unassuming brown bovine from the south of Brazil has made history as the first transgenic cow capable of producing human insulin in her milk. The advancement could herald a new era in insulin production, one day eliminating drug scarcity and high costs for people living with diabetes. Read more ›

Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages... Read more ›
