Different coarse-grained contents affect mechanical characteristics of frozen soil under freeze-thaw cycles
Frozen soil in nature is a multiphase composite geomaterial consisting of mineral solid particles, ice crystals, unfrozen water, and porous air. In cold regions, the deformation properties of frozen soils with different coarse-grained contents change.....»»
How climate change affects deer—experts draw findings from 20 years of research
Temperature, rainfall, snow and extreme weather events are all factors linked to climate change that directly affect wildlife. Understanding the impact of these factors on the physiology, population dynamics and distribution of different deer species.....»»
Study suggests moon may have been captured from space rather than formed from collision particles
Over six missions to the moon, from 1969 to 1972, Apollo astronauts collected more than 800 pounds of lunar rock and soil. Chemical and isotopic analysis of that material showed that it was similar to the rock and soil on Earth: calcium-rich, basalti.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
Study offers new explanation for Siberia"s permafrost craters
Mysterious craters that first appeared in the Siberian permafrost a decade ago were caused by climate change-driven pressure changes that explosively released methane frozen underground, a new study reports. The research offers a fresh take on the or.....»»
Study explores what families fight about: Communication, moods, and chores
Conflict in families can negatively affect individuals' well-being and relationships. But what exactly do families today fight about, and is conflict in the home generally more severe between couples or between parents and children?.....»»
Injecting manure into growing cover crops can cut pollution, support corn crops
Nitrogen in the soil, where plants can readily utilize it, benefits crop growth and health. However, nitrogen leaving the soil—whether through leaching into the groundwater table, flowing with surface runoff into streams or escaping into the air as.....»»
Existence of an Earth-like planet around a dead sun offers hope for our planet"s ultimate survival
The discovery of an Earth-like planet 4,000 light years away in the Milky Way galaxy provides a preview of one possible fate for our planet billions of years in the future, when the sun has turned into a white dwarf, and a blasted and frozen Earth ha.....»»
Study finds extreme temperatures increase mortality rates, with heat disproportionately affecting minorities
A new study examined how extreme temperatures in the United States significantly affect mortality among different racial groups and found that both cold and hot days increase mortality rates, with the latter disproportionately affecting underrepresen.....»»
Researchers explore novel approach to map forest dieback in satellite images
Forests and woodlands cover one third of Earth's surface and play a critical role in carbon sequestration, water regulation, timber production, soil protection, and biodiversity conservation. Accelerated by climate change, the decline of these and ot.....»»
Frozen in time: Rock fossils hint at Mars"s ancient climate
Long ago, flowing wind and water shaped Mars's malleable sand and sediment into dunes, ripples and other landscape patterns, called bedforms. Over billions of years, some of these landforms hardened into rock—scientists then call them paleo-bedform.....»»
Heat, animal illness and erosion risks to affect NZ agriculture with changing climate
Scientists at Manaaki Whenua—Landcare Research have worked closely with researchers from NIWA, AgResearch and Plant & Food Research to model the likely risks of a warming climate across different agricultural sectors in New Zealand. The study is pu.....»»
Rising waters, waning forests: Scientists are using tree rings to study how rising sea levels affect coastal forests
Sunlight filters through the canopy of pines, holly, sweet gum, and red maple while bird calls echo in the distance. These coastal forests may seem like others in the Mid-Atlantic, but a hidden challenge looms. Standing tall next to their salt marsh.....»»
Murine study suggests cosmic radiation in outer space may affect long-term cognition
During missions into outer space, galactic cosmic radiation (GCR) will penetrate current spacecraft shielding and thus pose a significant risk to human health......»»
Answers company recalls raw dog food due to salmonella, listeria threat
A raw diet pet food company is recalling cartons of frozen beef and chicken dog food that could be tainted with salmonella or listeria germs......»»
Citizen science data characterizes threat due to visits by swarms of jellyfish on the coast of the province of Malaga
A little-known threat to tourists in the form of stinging jellyfish could affect those who like to take a dip in between lazing in the heat on the sun-drenched beaches of Málaga (Spain). These sea creatures are of increasing concern along Spain's mo.....»»
Testing the legitimacy of consent and waiver in criminal cases
Criminal suspects, defendants and offenders face many choices that affect their liberty, in situations ranging from searches of their property or data to interrogations and plea deals. Judicial doctrine considers these choices to be valid when they a.....»»
Human urine could be used as eco-friendly crop fertilizer: Study
Bacterial communities in soil are as resilient to human urine as synthetic fertilizers—making recycling the bodily fluid as a fertilizer for agricultural crops a viable proposition, according to a new study......»»

Study shows organonitrates in atmospheric particles vary with altitude
While atmospheric particles directly affect climate (e.g., cloud formation), sampling atmospheric particles aloft is practically challenging. Therefore, a full understanding of how particle composition is linked to environmental function remains limi.....»»
Young professionals are struggling to socially adapt in the workplace; how educators can help
Despite ongoing worries about how artificial intelligence will affect jobs, research shows that employers increasingly value something that only human workers can provide—soft skills. These include knowing how to communicate with co-workers, put ot.....»»
