Neonatal intestinal disorders that prevent infants from getting the nutrients they need may be caused by defects in the lysosomal system -- or cell recycling center -- that occur before weaning. Scientists provide a new target for research and future therapies to help infants unable to absorb milk nutrients and gain weight.
Researchers at the University of California, San Diego have shown that a micromotor fueled by stomach acid can take a bubble-powered ride inside a mouse. These tiny motors, each about one-fifth the width of a human hair, may someday offer a safer and more efficient way to deliver drugs or diagnose tumors. The experiment is the first to show that these micromotors can operate safely in a living animal.
Scientists have reconstructed the past climate for the region around Cantona, a large fortified city in highland Mexico, and found the population drastically declined in the past, at least in part because of climate change.
Ecologists have found the conservation of aquatic ecosystems in Canada has not kept pace with the country's changing landscape, and a prioritization of protection is needed. This new assessment of environmental, human census and business pattern data shows climate warming and northward expansion of human activities over a decade, and can be used to guide strategies for managing freshwater resources by highlighting the regions where humans are now having the greatest impact.
This week from AGU: iceberg sounds, underground water reserves, and volcanoes on Mars.
Canine distemper, a viral disease that's been infecting the famed lions of Tanzania's Serengeti National Park, appears to be spread by multiple animal species, according to a study published by a transcontinental team of scientists.
The eighth tropical cyclone of the Southern Indian Ocean season has formed far from land, and the Tropical Rainfall Measuring Mission or TRMM satellite saw some heavy rain east of the storm's center.
A collaborative study suggests that the island's native culture reacted to natural environmental barriers to producing sufficient crops.
Citizen scientists wanted to know: what are the yellow objects on these infrared images from the Spitzer Space Telescope? The team of astronomers working with Milky Way Project -- a project that asks volunteers to study Spitzer images for patterns showing star formation -- decided to take a closer look. Iowa State's Charles Kerton and other astronomers report in the Astrophysical Journal that the so-called 'yellowballs' are part of the development of massive stars.
Brain surgery for otherwise hard-to-treat epilepsy is effective for up to 15 years, according to a new survey by Henry Ford Hospital physicians. The findings were based on a telephone survey of patients who had a portion of their brains surgically removed, or resected, to treat localization-related epilepsy at Henry Ford during an 18-year period.
