Mars water loss shaped by seasons and storms
Mars has lost most of its once plentiful water, with small amounts remaining in the planet's atmosphere. ESA's Mars Express now reveals more about where this water has gone, showing that its escape to space is accelerated by dust storms and the plane.....»»
As temperatures rise, researchers identify mechanisms behind plant response to warming
Microscopic pores on the surface of leaves called stomata help plants "breathe" by controlling how much water they lose due to evaporation. These stomatal pores also enable and control carbon dioxide intake for photosynthesis and growth......»»
Report: Global drought threatens food supplies and energy production
In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many.....»»
Why are so many historically rare storms hitting the Carolinas?
Hurricane Helene caused deadly and destructive flooding when it swept through the Southeast on Sept. 26–29, 2024. Across a broad swath of western North Carolina, where the worst flooding occurred, the amount of rainfall exceeded levels that would b.....»»
DirecTV/Dish merger has a problem as debt holders object to $1.6 billion loss
Debt holders oppose $1.6 billion value reduction, throwing wrench into TV merger. DirecTV's agreement to buy the Dish satellite and streaming TV business from EchoStar is facing o.....»»
Protein involved in the early stages of age-related macular degeneration offers hope for prevention
Age-related macular degeneration (AMD) is a leading cause of irreversible vision loss in the United States. Despite existing treatments, the underlying causes of this disease and effective therapies remain elusive. Research published in the journal D.....»»
Chemist challenges traditional views on crystal growth
Remember that old high school chemistry experiment where salt crystals precipitate out of a saltwater solution—or maybe the one where rock candy crystals form from sugar water? It turns out that your understanding of how crystals formed in those so.....»»
Demonstrating how Great Barrier Reef water quality targets can be achieved through gully remediation
A new study conducted at Bonnie Doon Creek on the lower Burdekin River in Queensland has demonstrated a significant reduction in sediment yield through large-scale remediation of alluvial gullies. The findings are published in the journal Internation.....»»
Unraveling the mystery of dormancy in food pathogens for more effective elimination
Listeria monocytogenes, a bacterium that causes listeriosis, a serious disease, can go into dormancy when confronted with environmental stress, for example in the presence of detergents or in water devoid of nutrients. It then becomes undetectable by.....»»
Beyond "one pore at a time": New method of generating multiple, tunable nanopores
Nanoporous membranes with atomic-scale holes smaller than one-billionth of a meter have powerful potential for decontaminating polluted water, pulling valuable metal ions from the water, or for osmotic power generators......»»
Dish creditors “revolt” over DirecTV merger, try to block loss-making deal
Debt holders oppose $1.6 billion value reduction, throwing wrench into TV merger. DirecTV's agreement to buy the Dish satellite and streaming TV business from EchoStar is facing o.....»»
Study links hurricanes to higher death rates for nearly 15 years after a storm
New research reveals hurricanes and tropical storms in the United States cause a surge of deaths for nearly 15 years after a storm hits......»»
Predicting river flow dynamics using stable isotopes for improved ecosystem health
An international science team has made significant strides in understanding river flow dynamics. The findings leverage isotope hydrology techniques such as measuring stable isotopes in water molecules to elucidate the contributions of various water s.....»»
New findings can help improve our understanding of winter weather in the St. Lawrence River Valley
