Progress against sarcoma

...lp from some favorable, yet-unidentified factor in nearby joint cartilage. Based on the findings, Capecchi believes myoblasts are the likely source of synovial sarcoma in humans. Usually what we learn in mice is applicable to humans, but we have to prove it, although such experiments could not be conduct...

Why small dogs are small

Chase says one or more of six mutations in the short DNA regulatory sequence are suspected of reducing activity of the growth factor gene. From Wol...

Slow but sure -- Burned forest lands regenerate naturally

...Seed was provided by patches of surviving trees or nearby unburned forest, which were rarely more than a few hundred yards from fire-killed trees. The relationship of shrub competition with tree seedlings also was surprising. On low and middle elevation sites, there were actually more conifers where there w...

'Guardian of the genome' protein found to underlie skin tanning

...rete a hormone called alpha-MSH, which attaches to nearby skin cells called melanocytes and spurs them to produce skin-darkening pigment called melanin. The chain of events within keratinocytes that leads to alpha-MSH production, however, was a mystery. Investigators knew that alpha-MSH is created when an...

Their results also reveal that low-fountaining, boiling-over events appear to be the most hazardous scenarios. Title:4D simulation of explosive eruption dynamics at Vesuvius Authors: ...

Microfluidic chip helps solve cellular mating puzzle

...g out pheromone designed to catch the attention of nearby cells of the opposite mating type. When a prospective partner picks up this "scent," it alters its shape and sends a projection toward the source of the pheromone, leading to a cellular merger. This mating process is regulated by proteins inside the ...

Biologically inspired sensors can augment sonar, vision system in submarines

A nearby inlet draws many swimmers, surfers and sharks, which find all the splashing, kicking and other movements humans make in the water highly provocative, Burgess said. Shark attacks in Volusia County increased from nine in 2005 to 12 in 2006. Numbers o...
