Vicious Circles – how changes in the shape of DNA can drive cancer

The diploid human genome contains 23 pairs of chromosomes whose DNA encodes genes for life activities, such as cell division. Cancer corrupts those genes, making growth-promoting genes more active (oncogenes) or growth-inhibiting genes (tumor suppressors) less active. One of the most common genetic alterations causing... click to read more

The genetic metabolic component of anorexia nervosa

Anorexia nervosa is the deadliest psychiatric disorder and is notoriously challenging to treat. Currently, no medications are effective in its treatment, in part because we do not have a clear understanding of its biological basis. Despite myriad misconceptions, anorexia nervosa does not discriminate and can... click to read more

Ancient human DNA from a 10000 years old "chewing gum"

In recent decades ancient DNA has been continuously used as a part of the tool-kit for studying human history and evolution. Ancient human DNA is found in both organic and inorganic material, for example, bones, teeth, mummified materials, coprolites, soil, etc. Bones and teeth harbor the... click to read more

BioBits™: Making Hands-on Biology Experiences Accessible for Everyone

Molecular biology is difficult to teach in schools, since the concepts can't be seen and are instead represented with abstract diagrams in textbooks. Some schools have introduced hands-on activities, such as growing cells that glow green, to illustrate these ideas in real life and facilitate... click to read more
