Judging the WHO’s Reaction to the H1N1 (Swine Flu) Threat

Few global health decisions have created quite as much commotion as that on April 29, when the World Health Organization , responding to the escalating spread of the H1N1 flu, raised its pandemic alert level for the first time to phase 5, meaning that a full pandemic was considered imminent. As of May 11, the WHO has reported more than 4,600 cases in 30 countries — including 2,600 cases in nearly every state in the U.S., according to the Centers for Disease Control and Prevention — and the threat level remains at phase 5. But over the past two weeks, fears over H1N1 have cooled considerably, as the virus has failed to spread easily outside North America and the number of deaths from the disease has remained low, leaving the WHO fending off critics who questioned whether the international agency overreacted

(CNN) — A head-banging parrot who became a YouTube sensation has demonstrated that an ability to appreciate music and keep a rhythm is not unique to humans, scientists say. Snowball the cockatoo, who appears to bop his head, tap his claws and squawk enthusiastically to the Back Street Boys’ “Everybody” is one of several birds apparently capable of dancing to a beat, according to two studies published in the latest edition of the journal Current Biology.

All Sugars Aren’t the Same: Glucose Is Better, Study Says

Correction Appended: April 21, 2009 Think that all sugars are the same They may all taste sweet to the tongue, but it turns out your body can tell the difference between glucose, fructose and sucrose, and that one of these sugars is worse for your health than the others. In the first detailed analysis comparing how our systems respond to glucose and fructose, , researchers at the University of California Davis report in the Journal of Clinical Investigation that consuming too much fructose can actually put you at greater risk of developing heart disease and diabetes than ingesting similar amounts of glucose. In the study, 32 overweight or obese men and women were randomly assigned to drink 25% of their daily energy requirements in either fructose- or glucose-sweetened drinks
