American Scientists Working On Creating Chimeras: Half-Human, Half-Animal Embryos (ibtimes.com.au) 242

Researchers at the University of California, Davis are working on creating half-human, half-animal hybrid embryos dubbed chimeras to better understand diseases and its progression. But not everybody is thrilled about it. IBTimes reports: One of the aims of the experiment using chimeras is to create farm animals with human organs. The body parts could then be harvested and transplanted into very sick people. However, a number of bioethicists and scientists frown on the creation of interspecies embryos which they believe crosses the line. New York Medical College Professor of Cell Biology and Anatomy Stuart Newman calls the use of chimeras as entering unsettling ground which damages "our sense of humanity." They are not alone in voicing their opinion against the idea. Huffington Post adds: The project is so controversial that the National Institutes of Health has refused to fund it. The researchers are relying on private donors. Critics of these experiments say they are too risky because there is no way of knowing where the human stem cells will go. Will they just become a pancreas? Or could they become a brain? And if they become a brain, will the pigs who house them have human consciousness?

I'd imagine watts/m^2 very quickly turns into watts/$ when it comes to maintaining ever larger fields of panels.

When exactly one is more valuable to research than the other is up so some particularly smart person to work out (not me), but both aspects are valuable to improve over the long term.

Not to mention this has a direct impact on raw materials required to produce said panels.

They also offer a variety of services which I greatly appreciate in this day an age.

I don't have to lug around all my cds/dvds/Floppies every time I move and honestly I've gotten rid of all my physical media (external hard-drives excluded) about 2 international moves ago.

It automatically keeps all my games up to date, no more Battlefield 1942 patch hell.

As a store front it allows me to keep up to date on game releases and even pre-load certain titles.

Steam sales.

A robust offline mode which automatically works as long as you've downloaded the game and run it a single time while being connected online.

I use it as a unified launcher.

I use it as a communication tool dedicated to getting in touch with other people I know who are playing games and can easily organize matches of any game on our collective steam lists.

Also not all games come with the steamworks DRM and can be run freely without steam even being installed on the system. Granted you have to download it through Steam first, but that would apply to any digital store front. Not to mention I've never noticed the DRM in action, making it the most non-intrusive form so far and if it doesn't even bother me, I don't see much reason to rage about it if it means that Steam is more likely to stay in business.

I no longer have to input CD-keys or even worry about where I've physically kept the myriads of manuals containing them and installing software is as quick as simply wanting to play something and double clicking the title and download/installation is automatic. I don't have as much time to waste on gaming as I used to so streamlining it is in my best interest.

Having to live with the "fear" that one day my games will be gone is like worrying that a Jumbo jet will land on my house. Honestly, I'd just pirate the games I'd lost.

Because people are stupid and forget about important things all the time.

It's a campaign revolved around awareness. If you notice all the lights going out around you and you take a moment to think "Ooh, that's neat" and then figure out it's earth day then maybe sometime next week you'll turn off a light you would normally have left on or turned down (up?) the AC a couple of degrees. But more often than not you will forget it, because people are stupid and forget about important things all the time.

Sure it's futile, but at least it's something.

"Lazarus Project" Clones Extinct Frog 154

cylonlover writes "Australian scientists have successfully revived and reactivated the genome of an extinct frog. The 'Lazarus Project' team implanted cell nuclei from tissues collected in the 1970s and kept in a conventional deep freezer for 40 years into donor eggs from a distantly-related frog. Some of the eggs spontaneously began to divide and grow to early embryo stage with tests confirming the dividing cells contained genetic material from the extinct frog. The extinct frog in question is the Rheobatrachus silus, one of only two species of gastric-brooding frogs, or Platypus frogs, native to Queensland, Australia. Both species became extinct in the mid-1980s and were unique amongst frog species for the way in which they incubated their offspring."
