RTFA. it explains the process, simplified:

"Israeli scientists have created a detector, similar looking to a full-body scanner but with three concealed cartridges each containing eight specially trained mice. ....When the mice sense traces of drugs they run to a side chamber where the trigger an alarm, the magazine said.
Eran Lumbroso, and inventor whose company BioExplorers is hopeful a larger company will help with the final stages of development, said: "It is as if they are smelling a cat and escaping. We detect the escape."

Please read the paper's abstract. The ScienceNews article may be complete garbage, but the researchers:

-Are investigating post-transcriptional modification of RNA, not "mistakes"
-Wanted to methodically analyze RNA editing, since our understanding is limited. This was a study to contribute to the understanding of RNA modification mechanisms, not overturn the central dogma
-Someone here mentioned that we already know about A to I conversions in RNA. The abstract mentions these; they're not stupid/unaware- they are trying to find other conversions, and understand _where_ A to I and other modifications occur (where they always occur -> why do they occur at these sites/sequences of RNA)

Please mod this up so that more people read the abstract.


Central Dogma of Genetics May Not Be So Central 196

Amorymeltzer writes "RNA molecules aren't always faithful reproductions of the genetic instructions contained within DNA, a new study shows (abstract). The finding seems to violate a tenet of genetics so fundamental that scientists call it the central dogma: DNA letters encode information, and RNA is made in DNA's likeness. The RNA then serves as a template to build proteins. But a study of RNA in white blood cells from 27 different people shows that, on average, each person has nearly 4,000 genes in which the RNA copies contain misspellings not found in DNA."

I don't know about $450 laptops from experience, but the 3 toshiba laptops I've had and the ones I've seen other people use are not pieces of shit (I buy in the $700 - $900 range for the specs I want).

My toshiba e205 does not feel like its going to fall apart if I move it around. My laptop fits just fine in the designated sleeve in my backpack. And there's no balancing issues. The keyboard is off center by one key from the screen, but I have no issue with that, as long as my body is lined up with the center of the keyboard.

The power supply has gotten smaller of the years and is roughly 4-5" long, 3" wide and 2" deep. It's very light too.

Macbooks are high quality and I love the magnetic power supply connection, but there are other choices out there that are cheaper and still have high quality.
