...Amid the ensuing media bonanza, local health officials immediately announced a "full and urgent" investigation into Morton's death and ordered a batch of the vaccine to be withheld as a precaution. Less than a day later, a preliminary postmortem examination found that the vaccine was unlikely to have killed Morton and blamed instead a "serious underlying medical condition." Still, as many Western nations are about to begin massive inoculation programs against the H1N1 influenza, Morton's death underlines the cruel reality behind any vaccination campaign: there's always the risk that a small number of vaccine recipients will suffer...
...that frontline health workers, who should be among the first in line for the injections, might refuse over safety concerns. That could compromise health workers' ability to treat patients who are hospitalized with the disease. A study of 11 focus groups conducted in Canada prior to the H1N1 outbreak found that health-care workers might refuse to immunize their children and themselves if they believed the risks of a new vaccine outweighed the benefits, according to a report in the Emergency Health Threats Journal in August. Another study published last month in the online edition of the British Medical Journal...
...path of just such a discovery began in November 1994 with the unearthing of two pieces of bone from the palm of a hominid hand in the dusty Middle Awash region of Ethiopia. Within weeks, more than 100 additional bone fragments were found during an intensive search-and-reconstruction effort that would go on for the next 15 years and culminate in a key piece of evolutionary evidence revealed this week: the 4.4 million-year-old skeleton of a likely human ancestor known as Ardipithecus ramidus (abbreviated Ar. ramidus).

Figuring out the story of human origins is like assembling a huge, complicated jigsaw puzzle that has lost most of its pieces. Many will never be found, and those that do turn up are sometimes hard to place. Every so often, though, fossil hunters stumble upon a discovery that fills in a big chunk of the puzzle all at once - and simultaneously reshapes the very picture they thought they were building...
...studies published in the Oct. 2 special issue of Science - 11 papers by a total of 47 authors from 10 countries - researchers unveiled Ardi, a 125-piece hominid skeleton that is 1.2 million years older than the celebrated Lucy (Australopithecus afarensis) and by far the oldest one ever found. Tim White of the University of California, Berkeley, a co-leader of the Middle Awash research team that discovered and studied the new fossils, says, "To understand the biology, the parts you really want are the skull and teeth, the pelvis, the limbs and the hands and the feet...
