Scientists searching for the genetic roots of autism have found something surprising: In families where two children have been diagnosed with the disorder, siblings don’t often share the same gene changes. The new study fits into a larger body of research suggesting the genetics of autism are still poorly understood. It also raises the possibility that the disorder isn’t usually inherited, even when it runs in families. Instead, it could be that some other factor, like a shared environment or common conditions during pregnancy.
Scientists have cracked the code for un-boiling hard-boiled egg whites and it could have huge implications for cancer research.  Egg whites are made of proteins that start out with a certain shape. Once you boil them, the proteins stay intact but they change their conformation.  This is a big deal because even chemists assumed once you hard-boiled an egg it was game over. But researchers have been able to reverse the process so that proteins can be recovered and reused. 
Most of us know that too much cholesterol in the blood can bring on dangerous clots that lead to heart attacks and stroke. And recent studies show that the build up of these fats in the blood vessels doesn’t happen overnight it takes years of gradual deposits to narrow a vessel. In the latest study of healthy people who were followed for about 15 years on average, researchers say having even mildly elevated cholesterol levels can increase risk of having later heart problems by as much as 40%. The researchers argue that having high cholesterol for many years even if it starts when you’re young should be a new risk factor that doctors and patients consider when discussing their risk of heart disease.
A new study supports the notion that thyroid disorders can cause significant reproductive problems for women. The report's authors believe that testing for thyroid disease should be considered for women who have fertility problems and repeated early pregnancy loss. 2.3 percent of women with fertility problems had an overactive thyroid (hyperthyroidism), compared with 1.5 percent of those in the general population. The condition is also linked with menstrual irregularity. The thyroid produces hormones that play key roles in growth and development.
