Road salts and other human sources are threatening world's freshwater supplies
- ScienceDaily
- 21/4/12 22:18
When winter storms threaten to make travel dangerous, people often turn to salt to melt snow and ice. Road salt is an important tool for safety, but a new study warns that introducing salt into the environment -- for de-icing roads, fertilizing farmland or other purposes -- releases toxic chemical cocktails that create a serious and growing global threat to our freshwater supply and human health.

'Spectacle of nature': A Denali glacier is speeding downhill, potentially hampering climbers and increasing flood risk
A Denali glacier suddenly moving at a speedier clip is intriguing scientists, increasing the risk of nearby flooding and potentially closing off some climbing routes on the mountain this season.
Researchers find bubbles speed up energy transfer
Energy flows through a system of atoms or molecules by a series of processes such as transfers, emissions, or decay. You can visualize some of these details like passing a ball (the energy) to someone else (another particle), except the pass happens quicker than the blink of an eye, so fast that the details about the exchange are not well understood. Imagine the same exchange happening in a busy...
Road salts and other human sources are threatening world's freshwater supplies
When winter storms threaten to make travel dangerous, people often turn to salt, spreading it liberally over highways, streets and sidewalks to melt snow and ice. Road salt is an important tool for safety, because many thousands of people die or are injured every year due to weather related accidents. But a new study led by Sujay Kaushal of the University of Maryland warns that introducing salt...
Bottom-up is the way forward for nitrogen reduction at institutions
Nitrogen is an element basic for life—plants need it, animals need it, it's in our DNA—but when there's too much nitrogen in the environment, things can go haywire. On Cape Cod, excess nitrogen in estuaries and salt marshes can lead to algal blooms, fish kills, and degradation of the environment.
Researchers engineer probiotic yeast to produce beta-carotene
Researchers have genetically engineered a probiotic yeast to produce beta-carotene in the guts of laboratory mice. The advance demonstrates the utility of work the researchers have done to detail how a suite of genetic engineering tools can be used to modify the yeast.
Common approach to diversity in higher education reflects preferences of white Americans
Increasing diversity remains a key priority at universities, especially in the wake of mass demonstrations in support of racial equality in 2020 following the death of George Floyd. Many universities are guided by the motivation that diversity enhances student learning, a rationale supported by the U.S. Supreme Court.
Plastic planet: Tracking pervasive microplastics across the globe
Really big systems, like ocean currents and weather, work on really big scales. And so too does your plastic waste, according to new research from Janice Brahney from the Department of Watershed Sciences. The plastic straw you discarded in 1980 hasn't disappeared; it has fragmented into pieces too small to see, and is cycling through the atmosphere, infiltrating soil, ocean waters and air....
Scientists discover three liquid phases in aerosol particles
Researchers at the University of British Columbia have discovered three liquid phases in aerosol particles, changing our understanding of air pollutants in the Earth's atmosphere.

Study showing how the brain retrieves facts and may help people with memory problems
- ScienceDaily
- 21/4/12 20:27
A shared set of systems in the brain may play an important role in controlling the retrieval of facts and personal memories utilized in everyday life, new research shows. Scientists say their findings may have relevance to memory disorders, including dementia, where problems remembering relevant information can impact on the daily life of patients.
