Scientists journey to southern Africa to unravel the secret world of elephant communication

...r offspring," O'Connell-Rodwell notes. "Once males reach puberty, around age 12, they get kicked out and start traveling alone or forming small bachelor herds." The search for a mate in this vast wilderness is further complicated by the elephant's reproductive biology. Females breed when they are in estrus...

Researchers find promising cancer-fighting power of synthetic cell-signaling molecule

...ministered orally and appear in often-difficult-to reach organs such as the prostate. "This is what suggested to us that Enigmols should be tested against other cancer types," Merrill explained. Subsequently, the researchers found that Enigmols suppress the growth of human prostate tumors implanted in mic...

Archaeological evidence places the earliest American inhabitants in the New World at around 14,000 years ago. Though Hey's estimates are more recent, they also indicate a high probability at this time period. With t...

Measles Deaths Worldwide Drop By Nearly 40% Over Five Years

...re than 130 million children are born and "we must reach each and every one with measles vaccination," said Dr LEE. The strong support of the Measles Initiative has been an important factor in the marked reduction of measles deaths in Africa. Launched in 2001, this successful partnership's core founding m...

Cellular Defects in Premature Aging Disease are Reversible

...ler, and affected children usually die before they reach their late teens. Less than two years ago, NIH-led researchers discovered that the genetic basis for HGPS is a single mutation in the gene encoding lamin A. Lamin A is a critical structural protein that acts as the scaffolding which holds a cell's n...
