Infections caused by a concerning type of antibiotic-resistant bacteria are on the rise in U.S. children, according to a new study published in the Journal of the Pediatric Infectious Diseases Society and available online. Although still uncommon, the bacteria are increasingly found in children of all ages, especially those 1-5 years old, raising concerns about dwindling treatment options.

If people need to reduce salt intake, relying on them to do it is less effective than teaching them how to flavor food with spices and herbs, according to research presented at the American Heart Association's Epidemiology&Prevention/Nutrition, Physical Activity & Metabolism Scientific Sessions 2014.

In the first phase of the study, 55 volunteers ate a low-sodium diet for four weeks. Researchers provided all foods and calorie-containing drinks. Salt is the main source of sodium in food.

In the second phase, half of the study volunteers participated in a 20-week behavioral intervention aimed at reducing their sodium intake to 1,500 mg/day by using spices and herbs. The other half reduced sodium on their own.

Scientists have discovered a new, persistent structure in one of two radiation belts surrounding Earth  - high-energy electrons in the inner Van Allen radiation belt display a persistent pattern that resembles slanted zebra stripes.

Surprisingly, this structure made of high-energy electrons is produced by the slow rotation of Earth, previously considered incapable of affecting the motion of radiation belt particles, which have velocities approaching the speed of light.

Genetic analysis of ancient poop found off the coast of Mexico suggests bighorn sheep may be native to Tiburón Island, the largest island in the Gulf of California and Mexico.

Bighorn sheep were not thought to inhabit Tiburón Island prior to their introduction in 1975 but scientists discovered fossilized dung in the mountains of Tiburón Island that challenges that assumption. Scientists compared the pellet-shaped poop to fecal pellets of other large mammals and extracted DNA to sequence and determine the origin.

An ancient stick insect species,
Cretophasmomima melanogramma from in Inner Mongolia at the Jehol locality, may have mimicked plant leaves for defense as far back as 126 million years ago, during the Cretaceous period, according to a new study.

In the television show "Cosmos", the writers and host Neil deGrasse Tyson implied that the atmosphere on Venus was due to a runaway greenhouse gas effect. They also said Giordano Bruno was a martyr for astronomy and that Saturn was the 'jewel' of the solar system.

The only one of those partially correct is that Earth has a variety of factors that make our built-in atmospheric carbon dioxide regulator work where the one on Venus does not – including geologic cycles that churn up the planet's rocky surface. We also have gravity that keeps hydrogen from escaping into space after solar radiation breaks them, as happens on Venus.
