Forget ‘live fast, die young’ – do the opposite instead
Posted by Steve Hill in categories: biotech/medical, genetics, life extension, neuroscience
So far, the only intervention that is known to increase lifespan in multiple species is caloric restriction (CR). Caloric restriction is known to increase lifespan in the majority of mouse strains tested[1]. The effects of CR have even been shown to influence how primates age and reduce the incidence of diabetes, cancer, cardiovascular disease, and brain atrophy[2].
Science has known about the effects of CR since the 1930s, when rat experiments first showed researchers this phenomenon[3]. However, despite the various health benefits of CR, how it delays aging has remained a mystery. A new study suggests that epigenetic drift may be the answer.

Robert Shmookler Reis Joins the LEAF Advisory Board
Posted by Steve Hill in categories: biotech/medical, genetics, life extension
We are very pleased to announce that Dr. Robert Shmookler Reis has joined the LEAF scientific advisory board. He studied at Harvard University (B.A.) and Sussex University (D.Phil.). He joined the University of Arkansas for Medical Sciences in 1980, where he holds the Udupa Chair of Gerontologic Research; he also serves as Affiliate Professor of Pathology at the Univ. of Washington in Seattle WA.
Dr. Robert Shmookler Reis is an expert in genetics whose work focuses on the molecular genetics of longevity and age-associated diseases and his team holds the world record for life extension in C. elegans (roundworms) making them live ten times their normal lifespan.

Closing in on cancer
Posted by Derick Lee in categories: biotech/medical, genetics, neuroscience
THE numbers are stark. Cancer claimed the lives of 8.8m people in 2015; only heart disease caused more deaths. Around 40% of Americans will be told they have cancer during their lifetimes. It is now a bigger killer of Africans than malaria. But the statistics do not begin to capture the fear inspired by cancer’s silent and implacable cellular mutiny. Only Alzheimer’s exerts a similar grip on the imagination.
Confronted with this sort of enemy, people understandably focus on the potential for scientific breakthroughs that will deliver a cure. Their hope is not misplaced. Cancer has become more and more survivable over recent decades owing to a host of advances, from genetic sequencing to targeted therapies. The five-year survival rate for leukemia in America has almost doubled, from 34% in the mid-1970s to 63% in 2006-12. America is home to about 15.5m cancer survivors, a number that will grow to 20m in the next ten years. Developing countries have made big gains, too: in parts of Central and South America, survival rates for prostate and breast cancer have jumped by as much as a fifth in only a decade.

Michio Kaku, Gregory Stack, And Yue Shao: Synthetic Human Embryos And Genetic Engineering [Opinion]
Posted by Shailesh Prasad in categories: bioengineering, biotech/medical, genetics
Michio Kaku and Gregory Scott discuss different aspects of genetic engineering in the video below. According to Kaku and Scott, parents will soon have different genetic engineering choices to make about their children. In addition, recent discoveries by Yue Shao have yielded a new classification of parentless synthetic human embryos.
With Yue Shao’s discovery, genetic engineers might be learning to grow synthetic human embryos from anonymous stem cells donated from IVF clinics. How far this genetic engineering technology goes remains to be seen.

Creating Human Beings from Skin Cells Is Possible
Posted by Shailesh Prasad in categories: bioengineering, biotech/medical, genetics, government, neuroscience
Stem cell research is one of my absolute favorite topics. This amazing field does not only reveal to us how our bodies function and develop, but also holds promising future applications that could help us treat severe diseases, which would not be treated otherwise. However, stem cell research can do more than just treat diseases. In this article, I will highlight the latest scientific breakthroughs to show you how we can turn a simple skin cell into a fully-grown genetically-engineered human being all thanks to the power of stem cells and genetic engineering.
Desperate times call for desperate measures
