    This Week in Wildlife: Scientists Discover Giant Rat, Ziggy Stardust-esque Spider

    By Stuart Fox Posted on 9.8.2009 8 Comments

    Forget the Orkin Man; with pests like this, you might need to call Ripley. Scientists have recently discovered two new, giant versions of common pests. In this corner, hailing from Papua New Guinea and weighing in at a hefty 3.3 pounds comes the the Bosavi woolly rat. And in the other corner, in the bright yellow outfit and representing Malaysia, please welcome Heteropoda davidbowie, "the Spider from Mars."

    The First Few Minutes After Death

    By Sam Barrett Posted on 10.31.2008 23 Comments

    After countless accounts of near-death experiences, dating as far back as ancient Greece, science is now taking serious steps forward to explore the nature of the phenomenon. A new project aims to determine whether the experience is a physiological event or evidence that the human consciousness is far more complicated than we ever believed.

    You know, there is already a well known method for experiencing impossible things, it's called hallucination. Which of these is more likely? -- Your thinkin' parts magically detach from your brain as you die. -- The trauma of oxygen loss induces hallucinations. Here's a hint: you can experience all kinds of fun things through oxygen deprivation (give it a try, I'll wait). There is no "soul", no "aura", no "brain waves latching onto passing microwave radiation" (hehe, I like that one). It's just a bunch of mushy neurons that depend on blood flow to do their jobs properly.

    Last Call?

    By Melinda Wenner Posted on 12.23.2008 10 Comments

    Nearly five decades ago, Americans learned that one of their most treasured habits—smoking—was lethal. This year, we could get more scary news, when scientists announce the results from Interphone, the largest-ever study to investigate whether cellphones cause cancer.

    Seriously? You're going to compare smoking to cell phone use? Are you kidding? That's ridiculously ignorant. Smoking is bad for you because you're inhaling toxic junk! Are you using your cell phone by lighting it on fire and breathing the smoke? Because if you're using a cell phone to, I dunno, make phone calls, you are no worse off than sitting in front of the television absorbing all those nasty photons. Three things to remember about "radiation": First, the "bad" kind is high energy, it can ionize atoms and cause cells to grow incorrectly (cancer). Second, Microwave radiation (radio waves a.k.a. wifi, broadcast TV, bluetooth, cell phones) is at the completely opposite end of the spectrum, lowest energy. Even visible light is higher energy, and it's not ionizing either. Third, your own body produces 100 Watts of infrared radiation whereas a typical cell phone produces 1 Watt of lower energy microwave radiation. But, don't take my word for it, I don't have a Masters degree in Physics like this guy: http://www.johnstonsarchive.net/environment/cellphone.html Some perspective: http://en.wikipedia.org/wiki/DBm
