Concentration of microparticles in lakes reflect nearby human activity and land use
Predicting where anthropogenic debris accumulates in aquatic ecosystems is necessary for its control and environmental remediation, but plastic and fiber pollution in lakes is not well studied. A study published in PLOS Biology by Andrew Tanentzap at.....»»
Study suggests less conformity leads to more innovation
Sociodiversity—the diversity of human opinions, ideas, and behaviors—is a driving force behind many positive developments......»»
A rare find in ancient Timorese mud may rewrite the history of human settlement in Australasia
Humans arrived in Australia at least 65,000 years ago, according to archaeological evidence. These pioneers were part of an early wave of people traveling eastwards from Africa, through Eurasia, and ultimately into Australia and New Guinea......»»
New report finds success in wild horse adoption program, critics disagree
A free-market environmental group has recommended expanding a Bureau of Land Management wild horse and burro adoption program that it says is saving taxpayers millions of dollars a year. A wild horse advocacy group has called the program a failure......»»
US reports 2nd human case of bird flu tied to dairy cow outbreak
A second case of bird flu has been found in a human, US health authorities announced Wednesday, less then two months after the first one as an outbreak of the disease circulates widely among dairy cows......»»
Second human case of bird flu linked to cows found—via text messages
Like the first case, the farm worker in Michigan only had an eye infection. Enlarge / Holstein dairy cows in a freestall barn. (credit: Getty | ) A dairy farm worker in Michigan has tested positive for an H5 bird flu vir.....»»
A merger of microbes: Study shows low-nutrient conditions alter viral infection
This much we know: When viruses infect bacteria—a common occurrence in oceans, soils, even human guts—the interaction results in the creation of entirely new organisms called "virocells." But scientists are still learning about how this merger of.....»»
Youths" attitudes in post-conflict Colombia reflect both cynicism and hope for peace, research finds
Following numerous attempts at peace, in 2016, the Colombian government and the FARC, the largest left-wing guerilla group, signed a peace treaty. Although Colombians were deeply divided about the treaty's prospects when it was first signed, the agre.....»»
A diaspora-based model of human migration
How do migrants choose their destinations? Existing models, known as "gravity models," use population size and travel distance as explanatory variables—and often fail, especially at the neighborhood scale. Many migrants prefer to move to a location.....»»
Study finds Black and Hispanic Americans are disproportionately exposed to wider temperature swings
Extreme heat can harm human health, but so can extreme temperature swings. Large daily temperature variation (DTV) has been associated with elevated mortality in studies around the world. Trees and other vegetation can lower DTV, as trees reduce temp.....»»
Study reveals cuddled cows who work as therapy animals show a strong preference for women compared to men
A new study, titled "Cow Cuddling: Cognitive Considerations in Bovine-Assisted Therapy" published in the Human-Animal Interactions journal, reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women wh.....»»
Academic calls for upgrade to sewage systems to protect health
The risk to public health from human feces in our rivers and seas will increase without action to create a wastewater system fit for the future, according to a Leeds academic......»»
Research team uncovers mechanism for spikelet development in barley
The inflorescence architecture of crop plants like barley is predominantly regulated by meristem activity and fate, which play a critical role in determining the number of floral structures for grain production......»»
New technique enables successful cultivation of stem cells on the surface of ionic liquids
The National Institute for Materials Science (NIMS) has established a technique for cultivating human mesenchymal stem cells, widely used in regenerative medicine, on the surface of an ionic liquid......»»
Study examines impacts of increased smoke on California lakes
As much as 70% of California was covered by wildfire smoke during parts of 2020 and 2021, according to a study from the University of California, Davis. The study, published in the journal Communications: Earth & Environment, combined lake-based sens.....»»

Detecting odors on the edge: Researchers decipher how insects smell more with less
Whether it's the wafting aroma of our favorite meal or the dangerous fumes seeping from a toxic chemical, the human sense of smell has evolved into a sophisticated system that processes scents through several intricate stages. The brains of mammals h.....»»
Highly sensitive fiber optic gyroscope senses rotational ground motion around active volcano
Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, Italy. A better understanding of the seismic activity.....»»
Researchers reveal annual distribution change of mountain runoff in Hexi Corridor
The response of runoff from inland river basins is becoming increasingly complex due to climate change and intensification of human activities, as well as underlying surface impacts. The annual distribution pattern of runoff shows spatio-temporal het.....»»
Math discovery provides new method to study cell activity, aging
New mathematical tools revealing how quickly cell proteins break down are poised to uncover deeper insights into how we age, according to a recently published paper co-authored by a Mississippi State researcher and his colleagues from Harvard Medical.....»»
Body lice may be bigger plague spreaders than previously thought
A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics......»»
