Cells Defend Themselves From Viruses, Bacteria With Armor Of Protein Errors

Red Orbit (Free subscription) | yesterday

When cells are confronted with an invading virus or bacteria or exposed to an irritating chemical, they protect themselves by going off their DNA recipe and inserting the wrong amino acid into new proteins to defend them against damage, scientists have discovered.These "regulated errors" comprise a novel non-genetic mechanism by which cells can rapidly make important proteins more resistant...

What Happens to Cold Blooded Animals in a Warming World (Slideshow)

Treehugger (Free subscription) | 11/19/2009

The European Green Lizard, Lacerta viridis , shows off a blue head while catching some rays. Lizards and other so-called "cold-blooded" animals have complex biochemistry: sometimes they have 4 to 10 different enzyme systems where humans would use only 1. Cold-blooded critters need this complexity so that their bodies function no matter what the weather forecast brings. To learn more about...

Researchers discover RNA repair system in bacteria

Physorg (Free subscription) | 10/12/2009

In new papers appearing this month in Science and the Proceedings of the National Academy of Sciences, University of Illinois biochemistry professor Raven H. Huang and his colleagues describe the first RNA repair system to be discovered in bacteria. This is only the second RNA repair system discovered to date (with two proteins from T4 phage, a virus that attacks bacteria, as the first).

This alarmist article in the Telegraph got a lot of attention from the warmmongers: " Arctic Ocean acid 'will dissolve shells of sea creatures within 10 years' ". Rebuttal from IceCap , October 4: "Alan [Siddons] calls attention to the following chart (enlarged here ): Alan continues: “Cold water absorbs CO2, right? And warm water releases it. So, on the premise that CO2 forms...

Three Science Moms Win Nobels

Gruntled Center (Free subscription) | 10/09/2009

Three women won science Nobel Prizes this week - Elizabeth Blackburn, Carol Greider, and Ada Yonath . All three are married mothers. After the dust-up over Lawrence Summers' entirely correct comments about the several factors that limit the proportion of women at the top of math and sciences professions, I have been particularly interested in women who combine biochemistry and family life. I think...

Another Day, Another Woman Wins a Nobel Prize for Nucleic Acid Biochemistry

Women in Science (Free subscription) | 10/08/2009

On the Nobel Prize front, 2009 is turning into a banner year for both nucleic acid chemistry and women scientists. As I posted earlier this week , two of the three winners of the 2009 Nobel Prize in Medicine ("for the discovery of how chromosomes are protected by telomeres and the enzyme telomerase") are women. And today it was announced that the Nobel Prize in Chemistry was awarded to Ada...
