It seems that the genetic risk of an APOE4 variant in the APOE gene would not only increase risk for Alzheimer’s but also would increase the chances of getting infected by the COVID-19 virus. The APO protein is involved in cholesterol metabolism and the immune system. However, its precise role in Alzheimer’s disease is as […]

A reported case study in a Colombian woman , member of a family carriers of a mutation in the presinilin 1 gene which leads to early onset Alzheimer’s, has shown that a certain mutation in the gene APOE3 can protect from the cognitive decline associated with Alzheimer’s disease. This woman was already aged 70 but […]

Believe it to not, little worms (C.elegans) are an useful tool for researchers studying aging. Specially, the genetics of aging. A recently released article in Cell Reports shows that gene modification in two specific cellular pathways drives 500% life extension in worms. Why worms? Worms are the ideal research subject for aging and genetics because […]

Nature versus nurture: how modern science is rewriting it

By Invited Researcher

The question of whether it is genes or environment that largely shapes human behaviour has been debated for centuries. During the second half of the 20th century, there were two camps of scientists – each believing that nature or nurture, respectively, was exclusively at play. This view is becoming increasingly rare, as research is demonstrating […]

Genetics of educational attainment

GeneticsNeurobiology

By José Ramón Alonso

Educational attainment, the years a person spends within the education system, generates interest among scientists because statistical analysis shows that there is a relationship between that value and different aspects of life including income when adults, state of health and even life expectancy. Geneticists analyze trends that can explain variations within a population by exploring […]
