Background: Weight reduction may reduce the severity of psoriasis, but little is known about the long-term effects.
Most big-game animals in Wyoming and the West can assess the quality of vegetation during the spring green-up to select the best patches of habitat during the growing season, a team of researchers led...
Many living things can respond to electric fields, either moving or using them to detect prey or enemies. Weak electric fields may be important growth and development, and in wound healing: it’s known...
The NAture of the Faint Far-Infrared Extragalactic Source Population: Optical/NIR and Radio Follow-Up Observationts of ISOPHOT Deep-Field Sources using the Keck, Subaru, and VLA Telescopes.
