Lazy? Your Genes May Be to Blame
"New research might help explain why some people have trouble getting off the couch. Experiments on rats suggest there could be a genetic predisposition to laziness."

Phenotypic and molecular differences between rats selectively bred to voluntarily run high vs. low nightly distances

Wedded bliss or blues? Scientists link DNA to marital satisfaction
"What makes some people more prone to wedded bliss or sorrow than others? Researchers at UC Berkeley and Northwestern University have found a major clue in our DNA. A gene involved in the regulation of serotonin can predict how much our emotions affect our relationships, according to a new study that may be the first to link genetics, emotions, and marital satisfaction."

Emotion Regulation Predicts Marital Satisfaction: More Than a Wives' Tale.
"Emotion regulation is generally thought to be a critical ingredient for successful interpersonal relationships."

Perilipin-2-null mice are protected against diet-induced obesity, adipose inflammation, and fatty liver disease

Gene Identified That Causes Obesity in Mice: Deleting Gene Eliminates Obesity, Could Work for Humans
"Researchers have discovered that deleting a specific gene in mice prevents them from becoming obese even on a high fat diet, a finding they believe may be replicated in humans."

Maybe some of the rats had A.D.D. Maybe some were so stupid they thought if they kept running they could escape.

   Dnews put her on more. I think she is doing the best job overall

[UPlayNetwork]

so why don't we improve the genetic makeup of humans to make them stronger, smarter and durable ?

I want to see more genetic connections with the sexual and gender minority commynity(LGBT) and Autism/Aspergers.

[burazfly]

I am not afraid of yours technology woman !
I am afraid of the people who control it.

2:42 "But unfortunately we'll have to wait until 2014 or later..."

Ok, it's 2014! Now tell us!

[marinebean]

OMG it's Cristen!!! I love your channel so much! It's so great to see you on DNews! :D

Emotions are caused by the secretion of special hormones from our brains such as dopamine . Hormones are special protein designed to stimulate a specific task and as we know that proteins are made by the process of transcription and translation in which a messenger RNA goes into the nucleus and copies a part of our genome to make the specific protein such as enzymes, hormones etc by copying its base pairs in the ribosome by a transfer RNA . So as proteins from which the majority of our body funtions are controlled by gene it is likable that our body also has a likable impact on them .and by the way this video was on how organisms inherit certain traits not to you go fancy pants and yell what genes can and could not do and also genetics contribute to much of our other body functions rather than just to construct us.

I can't disagree with science, but there is definitely way more to people being lazy than just your genes. We have too many comforts these days, televisions, internet, sofas, gaming consoles, easier access to books, movies, fast food, processed food, microwave food, cars. With all the things we have to make life easier for us, most of us could survive without exerting any energy. Drive to work, office job, drive back home, get shopping delivered to door, put a meal in the oven or microwave, sit down and watch tv, sleep, next day repeat, a lot of this leads to increase in nations becoming overweight. Years ago everyone had to work their ass off to make a living, there was no such thing as being lazy unless you were lucky enough to be rich, and unless you were born into a rich family, becoming rich wasn't something that happened because you were lazy. In some less prosperous countries today, people still do have to work their ass off, getting paid pennies for making shoes that sell for £100 in Western Society. None of these people are overweight or lazy. Immigrants may come and take our jobs, which can be a major problem, but at least they do not take everything for granted, they work hard, come home and appreciate just having a roof over their head, but yet we all complain of being bored despite how much we have and how lucky we are.

I love how she always points with both hands

[josha]

I'd sure like to get in her genes...LOLOL, GET IT?... Ty, I'm here all night.

Cure for baldness, my diabetes and my thyroid problems would be nice!

[BetaMind]

I really like the phobia/gene discovery where phobias can be passed down from gen to gen

[Pinoyk]

A genetic breakthrough that could prevent or stop cancer would be nice.

I understand genes from our two parents scrutinize each other and induce corrections in the other if felt necessary while fertilizing. This seems to be part of the process that improves future generations. I would love to see a video made on this theme. Thank you.

The only piece of media left from Discovery that is actually all science.

[generalx]

Not sure if it was real or not, but I remember reading an article about scientists having collected mold from Chernobyl. Apparently the mold was using mitochondria in to absorb radiation the same way that plants use chloroplast to absorb sunlight. The Idea was that perhaps our cells actually partially nourish themselves with certain types of radiation. I just thought it would be interesting to learn more about that.

When I had rats I had two, and I gave them a wheel, one loved running on it while the other preferred just laying about.... So technically science happened in my apartment? Cool :D

[rawstarmusic]

Intervention for virus and genes must be the 3 X Nobel price plus huge voluntary economic contributions from most people on earth. I wish talented astro scientists would work in this field for humanity.

both my parents ran cross country in college... I can't even get up to get food from the fridge
