he second tropical depression of the Eastern Pacific Ocean hurricane season formed close to the western Mexican coast this morning, and the third tropical depression may develop in the next day or two. NASA satellite imagery captured the two systems in one image, right after Tropical Depression 2-E formed.
ROCHESTER, Minn. -- For patients with quadriplegia, mutism and lower cranial nerve paralysis (locked-in syndrome), their only means of interacting with others is through vertical gaze and upper eyelid movements, using eye-coded communication strategies.
CAMBRIDGE, Mass. — Until now, astronomers have used telescopes to find Kuiper Belt objects (KBOs), moon-sized bodies, and obtain their spectra to determine what types of ices are on their surface. They have also used thermal-imaging techniques to get a rough idea of the size of KBOs, but other details have been difficult to glean. While astronomers think there are about 70,000 KBOs that are larger than 100 kilometers in diameter, the objects' relatively small size and location make it hard to study them in detail.
Not all patients with sickle cell disease receive laxatives after being treated with narcotics, despite recommendations from a collaborative panel of pediatric experts. These are the findings from a Nationwide Children's Hospital study examining patients from 29 pediatric hospitals, and appearing in Pediatric Blood & Cancer.
Gels, creams and sprays containing painkillers such as ibuprofen, diclofenac, ketoprofen, and piroxicam are safe and effective treatments for local pain, according to Cochrane Researchers. A new systematic review they have conducted shows that topical non-steroidal anti-inflammatory drugs (NSAIDs) are more effective than placebos for treating short-term pain and have few side effects.
Research published this week in PLoS Medicine finds that pregnant women with an inherited condition that makes them more likely to form blood clots only face a small increase in the risk that they might have a miscarriage or stillbirth. The findings also show that there is no significant association between this condition, known as inherited thrombophilia, and placenta-related problems in pregnancy, suggesting that the prescription of drugs to women with thrombophilia to prevent these problems would be premature.
Satellite imagery captured a visible look at System 92L earlier today, and it seems to be running into an environmental road block: upper level winds that are lessening its chances for development into a tropical cyclone.
By any measure, Lutetia is quite large. Planetary scientists believe that it is a primitive asteroid left on the shelf for billions of years because no planet consumed it as the Solar System formed. Indeed, most measurements appear to back this picture, making the asteroid out to be a 'C-type', which contains primitive compounds of carbon.
GREENBELT, Md. -- The Solar X-Ray Imager instrument aboard the GOES-15 satellite has just provided its first light image of the sun, but it required a lot of experts to make it happen.
The use of medications that increase sensitivity to the sun, combined with exposure to sunlight, appears to be associated with the risk of age-related cataract, according to a report posted online today that will appear in the August print issue of Archives of Ophthalmology, one of the JAMA/Archives journals.
Washington, D.C.—Scientists at the Carnegie Institution's Geophysical Laboratory, with colleagues, have discovered a much higher water content in the Moon's interior than previous studies. Their research suggests that the water was preserved from the hot magma that was present when the Moon began to form some 4.5 billion years ago, and that it is likely widespread in the Moon's interior. The research is published in the on-line early edition of the Proceedings of the National Academy of Sciences the week of June 14.

An area of low pressure referred to by meteorologists as "System 92L" in the Atlantic Ocean seems ripe for development and NASA infrared satellite imagery revealed areas in the low that have strong convection. Convection refers primarily to atmospheric motions in the vertical direction, or rising warm air that condenses and forms clouds.
