Although Sauer is no stranger to generating publicity for his causes, he added his name to the Republican contenders for governor with little fanfare Monday morning.

Study Says DNA's Power to Predict Illness Is Limited - 0 views
Epigenetics Seeks Clues to Mental Illness in Genes' Life Story - Science in 2011 - NYTi... - 0 views

epigenetics, the study of how people’s experience and environment affect the function of their genes.
-
Studies suggest that such add-on, or epigenetic, markers develop as an animal adapts to its environment, whether in the womb or out in the world — and the markers can profoundly affect behavior.
-
In studies of rats, researchers have shown that affectionate mothering alters the expression of genes, allowing them to dampen their physiological response to stress. These biological buffers are then passed on to the next generation: rodents and nonhuman primates biologically primed to handle stress tend to be more nurturing to their own offspring, and the system is thought to work similarly in humans.

Genes Are No Crystal Ball For Disease Risk - Science News - 0 views
-
For all but four diseases, the genetic data would fail to determine who is likely to contract the condition in most cases,
-
genetics are only part of the story when it comes to determining health. Lifestyle, environment and random chance play a bigger role than genes, or work with genes, to cause or protect against disease.
Old Cancer Drugs Offer New Tricks - Science News - 0 views
-
Drugs that alter some chemical tags on DNA make cancer cells behave more like normal cells
-
And the drugs seem to make cancer cells more susceptible to chemotherapy and attacks from the immune system.
-
drugs called azacitidine and decitabine, when used in low doses, change gene activity in leukemia and breast cancer cells in the lab. If DNA is a cell’s hard drive, then chemical tags attached to the DNA or DNA-packaging proteins called histones serve as software packages to tell the hard drive how to function. This type of chemical programming is called epigenetics.
Stem Cell Treatment Spurs Cartilage Growth - Science News - 0 views
-
A small molecule dubbed kartogenin encourages stem cells to take on the characteristics of cells that make cartilage, a new study shows
-
And treatment with kartogenin allowed many mice with arthritis-like cartilage damage in a knee to regain the ability to use the joint without pain.
-
Kartogenin steers the stem cells to wake up and take on cartilage-making duties. This is an essential step in the cartilage repair that falls behind in people with osteoarthritis, the most common kind of arthritis, which develops from injury or long-term joint use.

Mysterious Noncoding DNA: 'Junk' or Genetic Power Player? | PBS NewsHour - 0 views
-
Genes represent only a tiny fraction -- 1 percent -- of our overall genetic material. Then there's the other 99 percent of our DNA -- the stuff that doesn't make protein
-
Researchers have found that some of this noncoding DNA is in fact essential to how our genes function and plays a role in how we look, how we act and the diseases that afflict us.
-
Embedded in this 99 percent is DNA responsible for the mechanics of gene behavior: regulatory DNA. Greg Wray of Duke University's Institute for Genome Sciences and Policy describes the regulatory DNA as the software for our genes, a set of instructions that tells the genome how to use the traditional coding genes.

Human Genome Project Science - 7 views
-
The human genome contains 3164.7 million chemical nucleotide bases (A, C, T, and G).
-
The average gene consists of 3000 bases, but sizes vary greatly, with the largest known human gene being dystrophin at 2.4 million bases.
Missing Lincs - Science News - 6 views
-
-
Only now have scientists begun identifying the previously invisible contractors who make sure that materials get where they are supposed to be and in the right order to build a human being or any other creature. Some of these little-known workers belong to a class of molecules called long intergenic noncoding RNAs.
-
And the lincRNAs originate in what scientists used to view as barren wastelands between protein-coding genes. But new research is showing that these formerly underappreciated workers have important roles in projects both large and microscopic.

Exercise Brings On DNA Changes - Science News - 2 views
-
These alterations turn on genes that regulate a cell’s energy.
-
Genes can be turned on or off by a process known as methylation, in which a methyl group — consisting of one carbon atom and three hydrogen atoms — is added to DNA.
Concerns Raised about Genetically Engineered Mosquitoes - NYTimes.com - 2 views

These mosquitoes are genetically engineered to kill — their own children.

The results, and other work elsewhere, could herald an age in which genetically modified insects will be used to help control agricultural pests and insect-borne diseases like dengue fever and malaria.
