Researchers at the Woods Hole Oceanographic Institution and other institutions have found that delta areas worldwide have gained land in the past 30 years, despite river damming. But recent land gains...
Most of the frogs alive today owe a big thank you to the asteroid or comet that delivered the coup de grace to the dinosaurs.A new study by Chinese and American biologists shows that if the ...
Scientists have gotten better at predicting where earthquakes will occur, but they’re still in the dark about when they will strike and how devastating they will be.In the search for clues that will h...
Background: Some previous studies have indicated that a low basal metabolic rate (BMR) is an independent predictor of future weight gain, but low rates of follow-up and highly select populations may l...

Geophysical monitoring of the ground above active supervolcanoes shows that it rises and falls as magma moves beneath the surface of the Earth. Silica-rich magmas -- like those in the Yellowstone regi...
Background: There is a paucity of studies that have prospectively tested the energy surfeit theory of obesity with the use of objectively estimated energy intake and energy expenditure in humans. An a...
Background: A dietary protein intake higher than the Recommended Dietary Allowance during an energy deficit helps to preserve lean body mass (LBM), particularly when combined with exercise.
An adequate supply of protein and essential amino acids is of fundamental importance for normal child growth and development. Because pediatric nutrition research evolved from treating and preventing ...
Background: Abnormal gestational weight gain is associated with unfavorable pregnancy outcomes. Several risk factors have been identified, but the effect of macronutrient intake during pregnancy on ge...
Based on the bounds in the paper by Boyd and Doyle (Comparison of peak and RMS gains for discrete-time systems, Systems and Control Letters, 9:1-6), we present simple upper and lower bounds for the el...
Lasers — devices that deliver beams of highly organized light — are so deeply integrated into modern technology that their basic operations would seem well understood. CD players, medical diagnostics ...
