“I’m strong to the finich, ‘cause I eats me spinach!” said Popeye the Sailor Man.
While you may not gulp spinach by the can-fuls, if you love spanakopita or your go-to appetizer is spinach artichoke dip, then you’ll be excited to know that new research out of Boyce Thompson Institute (BTI) will make it even easier to improve this nutritious and delicious, leafy green.
The vast majority of cow-calf producers in Tennessee and the Southeast using a defined calving season have long favored spring calving; however, researchers at the University of Tennessee Institute of Agriculture have evaluated the risk and returns for a fall calving season, proving once again that timing is everything.
Selecting an optimal calving season involves a complex set of factors including nutritional demands of brood cows, forage availability, calf weaning weights, calving rates, seasonality in cattle, and feed prices and labor availability.
As world leaders and civil society representatives gather today in Cancun, Mexico, for a biennial United Nations forum on preventing and mitigating disaster impacts, the UN today launched an updated plan to increase the number of cities and towns with the capacity to reduce their disaster losses by 2020.
Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded to the detriment of a balanced ecosystem.
That’s the main finding of a study appearing May 23 in Nature Communications that analyzed the relationship between top predators on three different continents and the next-in-line predators they eat and compete with. The results were similar across continents, showing that as top predators’ ranges were cut back and fragmented, they were no longer able to control smaller predators.
A new University of Washington study shows that the textbook understanding of global chemical weathering — in which rocks are dissolved, washed down rivers and eventually end up on the ocean floor to begin the process again — does not depend on Earth’s temperature in the way that geologists had believed.
Pointing the National Science Foundation’s Very Large Array (VLA) at a famous galaxy for the first time in two decades, a team of astronomers got a big surprise, finding that a bright new object had appeared near the galaxy’s core. The object, the scientists concluded, is either a very rare type of supernova explosion or, more likely, an outburst from a second supermassive black hole closely orbiting the galaxy’s primary, central supermassive black hole.
