America"s dairy farms are disappearing, down 95% since the 1970s—milk price rules are one reason why
Milton Orr looked across the rolling hills in northeast Tennessee. "I remember when we had over 1,000 dairy farms in this county. Now we have less than 40," Orr, an agriculture adviser for Greene County, Tennessee, told me with a tinge of sadness......»»
Scientists discover nonstomatal control of water loss in critical crops
Scientists have discovered that certain plants can survive stressful, dry conditions by controlling water loss through their leaves without relying on their usual mechanism—tiny pores known as stomata......»»
New algorithm rights wrongs of precipitation-type classification over Tibetan Plateau
Like many natural phenomena, precipitation can be both a blessing and a scourge to human life. On the one hand, it supplies our rivers and fields with water; on the other hand, it can cause floods, landslides, and other natural disasters. Either way,.....»»
Study finds mine-drainage treatment cost effective, but far more costs lay ahead
New research led by the University of Pittsburgh shows that state and federal appropriations allowing Pennsylvania to treat abandoned mine drainage works to both successfully and cost effectively clean up the acidic water—particularly to the benefi.....»»
What killed fish for miles in the South River? Atlanta officials are investigating
Officials are investigating a pollution incident that occurred earlier this month a few miles south of downtown Atlanta, which local water advocates say sent toxins into a tributary of the South River and killed fish for miles downstream......»»
Researchers use training model to map planted and natural forests via satellite image
While planting trees may seem like an easy win to combat climate change, planted forests often encroach on natural forests, wetlands, and grasslands. This can reduce biodiversity, disturb the natural environment, and disrupt carbon and water cycling......»»
Paying attention to errors can improve fused remote monitoring of lakes, researchers say
Lakes can tip the scales from healthy to potential environmental hazard quickly when they become eutrophic. In this state, an abundance of nutrients accelerates algae growth, which then crowd the water's surface and block light from reaching organism.....»»
New "grumpy" fish species discovered in the Red Sea
A team of researchers at the King Abdullah University of Science and Technology and the University of Washington has discovered a new species of fish that seems perpetually displeased. The researchers decided to call this new species the grumpy dwarf.....»»
Exceptional new fish fossil sparks a rethink of how Earth"s geology drives evolution
Coelacanths are deep-sea fish that live off the coasts of southern Africa and Indonesia and can reach up to two meters in length. For a long time, scientists believed they were extinct......»»
South Sudan May See the First Permanent Mass Displacement Due to Climate Change
Protracted flooding has engulfed the country’s Sudd region due to more water entering the Nile upstream, which is driving conflict and disease and is potentially leaving the region uninhabitable......»»
Del Grande dealerships get ahead of California turf crackdown with low-water landscaping
When California announced a coming ban on watering ornamental turf, Del Grande Dealer Group made a plan to save water, save money and upgrade its Silicon Valley landscaping with native plants.....»»
Temperature fluctuations found to mar fish quality of large yellow croaker
Large yellow croaker is a highly nutritious and economically valuable mariculture species, but its perishable nature poses significant challenges in storage and transport. Cold chain logistics play a crucial role in maintaining seafood quality, but f.....»»
Researchers identify novel approach to minimize nitrogen loss in crops
While agriculture producers apply nitrogen fertilizer to supply nutrients to their crops, they can't always keep those nutrients in the soil for maximum efficiency, often losing them into the atmosphere or water supply as nitrates and nitrous oxide......»»
New method to break down forever chemicals uses nanoparticles and ultrasound
What do firefighting foam, non-stick cookware, water-repellent textiles and pesticides all have in common? They all contain per- and polyfluoroalkyl substances, or PFAS—human-made chemicals that don't break down naturally. It's no wonder, then, tha.....»»
Studies on pigeon-guided missiles, swimming abilities of dead fish among Ig Nobles winners
A study that explores the feasibility of using pigeons to guide missiles and one that looks at the swimming abilities of dead fish were among the winners Thursday of this year's Ig Nobels, the prize for comical scientific achievement......»»
Lakes drying up leave Greeks in despair
Lake Koronia, one of largest in Greece, is shrinking after a prolonged drought and a summer of record-breaking temperatures, leaving behind cracked earth, dead fish and a persistent stench......»»
An evolutionary battleground: Plants vs. microbes
Gazing out on a freshwater pond, you may see tiny green plants with oval-shaped leaves floating in clusters. In overgrown ponds, these plants coat the water's surface. These plants—called duckweed or water lentils—can grow so fast that they can d.....»»
Researchers reveal presence of microplastics in large pelagic fish in the Mediterranean
A research study co-led by the University of Barcelona and the Institute of Marine Sciences (ICM, CSIC), together with the Spanish Institute of Oceanography (IEO, CSIC), has revealed the worrying presence of microplastics in the stomachs of swordfish.....»»
The legacy of corn nitrogen fertilizer: Study shows lengthy impact in tile drained systems
Midwestern soils are among the most productive in the world, thanks in part to extensive tile drainage systems that remove excess water from crop fields. But water isn't the only thing flowing through tile drains. Nitrogen moves along with soil water.....»»
New fossil fish species scales up evidence of Earth"s evolutionary march
Climate change and asteroids are linked with animal origin and extinction—and plate tectonics also seems to play a key evolutionary role, "groundbreaking" new fossil research reveals......»»
