(Broadcast in High Definition where available.)

Scientists have long puzzled over the different fates of identical
twins: both have the same genes, yet only one may develop a serious
disease like cancer or autism. What's going on? Does something else
besides genes determine who we are? The "something else" turns out to
be a network of chemical switches that sit on our DNA, turning genes
off and on. Called collectively the epigenome, the switches appear to
play a major role in everything from how our cells keep their
identity to whether we contract dread diseases. Epigenetic switches
may even help mold our personalities. NOVA explores these startling
possibilities in "Ghost in Your Genes."

Here's what you'll find on the companion Web site:

Epigenetic Therapy
http://www.pbs.org/wgbh/nova/genes/issa.html
Dr. Jean-Pierre Issa examines the connection between epigenetics,
aging, and cancer.

Ask the Expert
http://www.pbs.org/wgbh/nova/genes/expert.html
Geneticist Randy Jirtle answers questions about how our
lifestyles, via epigenetics, can impact the health of our
children, and more.

A Tale of Two Mice
http://www.pbs.org/wgbh/nova/genes/mice.html
In this audio slide show, hear how the epigenome can make
identical-twin mice appear so different.

Gene Switches
http://www.pbs.org/wgbh/nova/genes/fate.html
Not all switches are epigenetic. As this slide show reveals, some
are genetic -- and amazingly powerful.

Also, a video preview of the program, Links & Books, the program
transcript, and a teacher's guide:

“Next on NOVA: "NOVA scienceNOW"

Wednesday, June 25 at 9 p.m.
(Check your local listings as dates and times may vary.)

Host and astrophysicist Neil deGrasse Tyson examines new findings on
dark matter, regaining lost memories, the art and science of digital
forensics, and how a crowd can prove "smarter" than each of its
individual members.

Dark Matter
http://www.pbs.org/wgbh/nova/sciencenow/0301/01.html
Turns out most of the universe is held together by a mysterious,
invisible substance.

Of Mice and Memory
http://www.pbs.org/wgbh/nova/sciencenow/0301/02.html
Mice placed in enriched environments can recover lost memories,
giving hope to those who study Alzheimer's.

Profile: Hany Farid
http://www.pbs.org/wgbh/nova/sciencenow/0301/03.html
This self-proclaimed "accidental scientist" is a digital
detective inventing new ways to tell if photos have been faked.

Wisdom of the Crowds
http://www.pbs.org/wgbh/nova/sciencenow/0301/04.html
Ask enough people to estimate something, and the average of their
guesses will get you surprisingly close to the right answer.

The journey continues on the NOVA scienceNOW Web site. Watch the
entire hour-long episode online starting June 26. E-mail scientists
from the broadcast with your questions. Explore a virtual world with
eight elements that may be critical for aging people to maintain
their mental health, try to tell real from digitally faked photos,
and watch video extras.

Next on NOVA: "Kings of Camouflage"

http://www.pbs.org/wgbh/nova/camo/

Tuesday, August 12 at 8 p.m.
(Check your local listings as dates and times may vary.)

Join NOVA on a voyage beneath the waves, where you'll discover a
bizarre, alien-like creature like no other. It's an animal with
eight sucker-covered arms growing out of its head, three hearts
pumping its blue-green blood, and a doughnut-shaped brain. It has
the ability to change its color and shape to blend in with seaweed
and rocks, and it has a knack for switching on electrifying light
shows that dazzle its prey. Perhaps most surprising of all, this
animal is quite intelligent, with a highly complex brain. In "Kings
of Camouflage," underwater cameras capture the extraordinary,
transformative powers of the cuttlefish.

Here's what you'll find on the companion Web site:

Quick Change Artists
http://www.pbs.org/wgbh/nova/camo/change.html
See how cuttlefish use their powers for much more than staying
hidden.

Anatomy of a Cuttlefish
http://www.pbs.org/wgbh/nova/camo/anatomy.html
Blue-green blood? Three hearts? Explore what sets cuttlefish
apart from other animals.

Spineless Smarts
http://www.pbs.org/wgbh/nova/camo/boal.html
Animal behaviorist Jean Boal ponders what cephalopods might
teach us about our own intellect.

Mating Trickery
http://www.pbs.org/wgbh/nova/camo/mating.html
Cuttlefish aren't the only wily suitors in the animal kingdom,
as this slide show reveals.

”

“And they have eyes like Species 8472.”

“Let me guess, that's the number of cuttlefish that've died in the war on terror.”

“Hmmm. I thought all they ever did was fund raising telethons and DNC panel shows.”
