Freiburg scientists decipher basic molecular control mechanisms behind cellular identity

A research team headed by Prof. Dr. Sebastian Arnold and Jelena Tosic from the Faculty of Medicine at the University of Freiburg has now succeeded in deciphering basic molecular control mechanisms by which stem cells decide which embryonic cell types to turn into.

Scientists uncover functions of mysterious organelles in stress response

Stress is a normal response to physical and emotional stimuli, particularly when people face changes in their lives. Though it’s a normal feeling, long-term stress may lead to a range of health conditions. Though people feel stressed from time to time, not all stress is bad.

Article reveals new mechanism of programmed aging

Nature has sentenced humans to an inevitable death from the time of birth; the natural instrument of execution is the aging process. According to modern scientific notions, only two root causes of aging can be: stochastic physiological damage or the implementation of a special genetic program in the body.

Uncovering the secret weapon of rabies viruses

In a new study published in the journal Cell Reports, scientists have discovered the exact site at which the immune system is disabled by the rabies virus, opening the way for a new and highly effective means of rabies prevention. This is a long-awaited discovery and could transform the field of rabies immunization.

Scientists explore expansion of cytotoxic CD4 T-cells in supercentenarians

Scientists from the RIKEN Center for Integrative Medical Science (IMS) and Keio University School of Medicine in Japan have used single-cell RNA analysis to find that supercentenarians--meaning people over the age of 110--have an excess of a type of immune cell called cytotoxic CD4 T-cells.

Fresh light on why aggressive breast tumors form and how they can be treated

New research presented at the Society for Endocrinology annual conference in Brighton appears to identify novel methods of therapy for an aggressive type of breast cancer as well as uncovering potential causative factors. The focus of the study is to show how common chemicals present in our surroundings are possibly putting women at risk of a type of breast cancer called triple negative breast cancer (TNBC).
