This Week's New Podcast
Cosmic Queries: Viruses, Outbreaks and Pandemics
August 11, 2013, 7:00pm ET/4:00pm PT
Infectious
disease expert Laurie Garrett is back to answer your questions about
viruses. First, she describes two current outbreaks: H7N9 influenza,
which killed 25% of its victims in China, and MERS-CoV, a genetic
relative of SARS. With pilgrimages like the Haj in October, Middle
Eastern Respiratory Syndrome Coronavirus is a serious pandemic concern
to the worldwide health community. Next, Laurie explains how viruses
like Ebola and HIV jump from bats and primates to humans through
“zoonosis” and why they’re so lethal when they do. All this, plus a
fungus that turns ants into zombies, pathogens that spread via rain, the
dangers of the anti-vaccine movement and, unfortunately, so much more.
The show will be on our website and iTunes this Sunday, August 11th at 7:00pm ET, and on SoundCloud and Stitcher by 7:15pm ET.

Cosmic Queries: Dark Matter and Dark Energy
August 4, 2013
If
dark matter is the longest unsolved problem in astrophysics, how can
Neil deGrasse Tyson answer your Cosmic Queries? Well, it turns out we do
know something about the stuff that makes up 96% of our universe. For
instance, how it affects the rotation of galaxies, and what would happen
if it disappeared. And whether dark matter is increasing as the
universe expands. You’ll find out if there are connections between black
holes and dark matter and what Hawking Radiation is. Did the recent
experiments on the ISS explain why dark matter doesn’t interact with
ordinary matter? Plus, Neil tells comic co-host Leighann Lord why he
thinks dark energy should be named Fred. One of our most popular shows
this season...if you haven't heard it – Listen now.

The Perseids Are Back this Weekend!
Posted August 7, 2013
Here’s a recipe for a bit of tasty cosmic cuisine this weekend:
1. Take a dash of stellar dust and debris from comet 109P/Swift-Tuttle.
2. Sprinkle into Earth’s atmosphere.
3. Lie back and watch the show.
And
if the weather cooperates and you’ve got clear skies – it’s looking
good for the NY metro area, so I’m hopeful – then you’re in for one of
the best meteor showers we get to see each year, The Perseids. At peak,
there can be as many as 100 meteors burning across the sky per hour. But
even if you just catch a few, they’re worth the effort. And, according
to NASA, the Perseids have the most “fireballs” of any meteor shower.

Nanobot Viruses and Biotechnology on StarTalk Radio
 Get
a sneak peak of this week's new podcast in this "Behind the Scenes"
video taken from the episode. In it, Laurie Garrett answers a fan's
cosmic query about whether we can create “nanobot” viruses that we could
use to fight disease, and if we do, how we can control them. She also
tells Neil deGrasse Tyson and Chuck Nice how we’re developing human
engineered microorganisms in the lab, including a competition where high
school students invent new life forms. Watch now.
