So people with H.I.V. now must take drugs every day for life, which some researchers say is not a sustainable solution for tens of millions of infected people.

This is what was done with the Trenton patient. Some of the man's white blood cells were removed from his body and treated with a gene therapy developed by Sangamo BioSciences. The therapy induced the cells to produce proteins called zinc-finger nucleases that can disrupt the CCR5 gene.

Dieting During Pregnancy Increases Risk Of Obesity And Diabetes For Offspring - 0 views
-
babies of mothers who diet around the time of conception and in early pregnancy, may have an increased risk of obesity and type 2 diabetes throughout their lives. This study provides exciting insights into how behavior can lead to epigenetic changes in offspring related to obesity and disease.
-
dieting around the time a baby is conceived may increase the chance of the child becoming obese later in life
-
changes in the genes that control food intake and glucose levels that may lead to obesity and diabetes.

Why having sex really IS the best thing to do
-
is better for evolution than self-reproduction
-
Having sex allows us to evolve more effectively than species which reproduce without a partner, according to tests that claim to finally prove the long-held theory.

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.

Shot of Young Stem Cells Makes Rapidly Aging Mice Live Much Longer and Healthier - Gate... - 1 views
-
animals that got the stem/progenitor cells improved their health and lived two to three times longer than expected,
-
"Our experiments showed that mice that have progeria, a disorder of premature aging, were healthier and lived longer after an injection of stem cells from young, healthy animals," Dr. Niedernhofer said. "That tells us that stem cell dysfunction is a cause of the changes we see with aging."
-
"Typically the progeria mice die at around 21 to 28 days of age, but the treated animals lived far longer -- some even lived beyond 66 days. They also were in better general health."

Changes in gene expression causes high BP in pregnancy - 1 views
-
Washington: Researchers have discovered that changes in the gene expression of a key enzyme may contribute to high blood pressure and increase susceptibility to forming blood clots in pregnant women with preeclampsia.
-
Epigenetics refers to changes in gene expression that are mediated through mechanisms other than changes in the DNA sequence.
-
The VCU team reported that thromboxane synthase – an important inflammatory enzyme – is increased in the blood vessels of expectant mothers with preeclampsia.The thromboxane synthase gene codes for this enzyme, which is involved in several processes including cardiovascular disease and stroke. This enzyme results in the synthesis of thromboxane, which increases blood pressure and causes blood clots.

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.
