Over 800 million people depend on cassava as a main food staple. Also known as manioc and yuca, this root vegetable also makes up around 50 percent of the caloric intake of around one-third of people in sub-Saharan Africa.

Unfortunately, it isn’t the most nutritious of food sources. As a result, iron and zinc deficiencies are sky high in many parts of Africa. It’s estimated that up to 75 percent of preschool children and 67 percent of pregnant women in Nigeria are anemic as a result of iron deficiency.

However, researchers have now developed super-charged cassavas using genetic engineering to enrich the plant with significantly higher levels of both iron and zinc.

Renowned Harvard University geneticist David Sinclair recently made a startling assertion: Scientific data shows he has knocked more than two decades off his biological age.

The race for the cure to aging sparks hope and hype among top scientists — plus billions of dollars in investment.

Psychiatry as a field, meanwhile, quivers with theoretical uncertainty. It has not become a sub-speciality of neurology, as one might have expected if mental illness mapped directly to neural behaviour. And common genetic variations with large effects on mental disorders are elusive. The various incarnations of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM) have enabled diagnostic consistency and the objectification of mental illnesses. But the DSM has resulted in overlapping diagnoses, and contrived symptom-cluster checklists. At times, it impinges on the territory of healthy mental function. Allen Frances, chair of the task force that wrote the manual’s fourth edition in 1994, revolted against out-of-control mental diagnosis in his 2013 book DSM: Saving Normal.

Adrian Woolfson weighs up a study on the role of evolution in conditions such as depression and anxiety.

CRISPR is a technique that is revolutionizing biomedical research through high-precision genome editing. However, even though it allows the creation or correction of mutations consisting of a single or few nucleotides with relative ease, it still possesses limitations for larger fragments of DNA in the genome. For instance, the genomic insertion of a gene that produces a fluorescent protein such as the widely-used GFP suffers from poor efficiency and involves complicated cloning steps.

The trauma of your ancestors may be carried in your gene’s memories.

The global population aged 60 or over is growing faster than all younger age groups and faces the tide of chronic diseases threatening their quality of life and posing challenges to healthcare and economy systems. To better understand the underlying biology behind healthspan — the healthy period of life before the first chronic disease manifestation — the scientists from Gero and MIPT collaborated with the researchers from PolyOmica, the University of Edinburgh and other institutes to analyze genetic data and medical histories of over 300,000 people aged 37 to 73 made available by UK Biobank.

The study published today in Communications Biology was lead by Dr. Peter Fedichev and Prof. Yurii Aulchenko. It shows that the most prevalent chronic conditions such as cancer, diabetes, chronic obstructive pulmonary disease, stroke, dementia, and some others apparently share the common underlying mechanism that is aging itself.

«According to Gompertz mortality law, the risk of death from all causes increases exponentially after the age of 40 and doubles approximately every 8 years», explains Peter Fedichev, founder and CSO of Gero. «By analyzing the dynamics of disease incidence in the clinical data available from UKB, we observed that the risks of age-related diseases grow exponentially with age and double at a rate compatible with the Gompertz mortality law. This close relation between the most prevalent chronic diseases and mortality suggests that their risks could be driven by the same process, that is aging. This is why healthspan can be used as a natural proxy for investigation of the genetic factors controlling the rate of aging, the “holy grail” target for anti-aging interventions».

As genetic genealogy gains momentum, one state considers barring police departments from using public DNA databases in criminal cases.

Very excited to have interviewed Dr. Michael Lustgarten in my role as longevity / aging ambassador for the ideaXme Show — Mike has been at the forefront of studying the 100 trillion organisms present in the human microbiome, their effect on human health and wellness, as well as a major proponent of metabolomics and biologic age tracking — A true future thinker in the area of extending human lifespan and healthspan

The scientists who developed the revolutionary gene-editing system known as CRISPR are improving it with new tools that make it work better.
