Unexpected discovery helps explain fundamental mystery about how muscles work

Researchers at the Max Delbrück Center for Molecular Medicine in the Helmholtz Association developed a mouse model that enables them to look inside a working muscle and identify the proteins that allow the sarcomere to contract, relax, communicate its energy needs, and adapt to exercise.

Killifish model helps unravel molecular events that lead to loss of protein homeostasis during brain aging

Aging is the main risk factor for dementia and Parkinson's disease. As age progresses, toxic protein aggregates pile up in the brain and impair neuronal function.

Researchers discover mechanical cause for cell extrusion

The outer or inner boundaries of organs in the human body are lined with so-called epithelial sheets. These are layers of epithelial cells that can individually change their 3D shape -- which is what happens during biological processes like organ development (morphogenesis), physiological equilibrium (homeostatis) or cancer formation (carcinogenesis).

Using stem cells to study the developmental effects of Neandertal DNA

Protocols that allow the transformation of human induced pluripotent stem cell (iPSC) lines into organoids have changed the way scientists can study developmental processes and enable them to decipher the interplay between genes and tissue formation, particularly for organs where primary tissue is not available.

'Microbial dark matter' can affect cholesterol levels in humans

In the darkest parts of the world where light fails to block out the unfathomable bounty of the stars, look up. There are still fewer specks illuminating the universe than there are bacteria in the world, hidden from sight, a whole universe inside just one human gut.

Researchers develop a simple tool for making mouse models of COVID-19

Until there are effective treatments or vaccines, the COVID-19 pandemic will remain a significant threat to public health and economies around the world. A major hurdle to developing and testing new anti-viral therapies and vaccines for COVID-19 is the lack of good, widely available animal models of the disease.
