Long Polymer Chains Dance The Conga
Understanding the steps to the intricate dance inside a cell is essential to one day choreographing the show. By studying the molecules that give a cell its structure, University of Illinois researchers are moving closer to understanding one of those steps: the conga line...
How Cells Protect Themselves From Cancer
Cells have two different protection programs to safeguard them from getting out of control under stress and from dividing without stopping and developing cancer. Until now, researchers assumed that these protective systems were prompted separately from each other...
Fruit Flies And Test Tubes Open New Window On Alzheimer's Disease
A team of scientists from SLU in Uppsala and University of Cambridge have discovered a molecule that can prevent a toxic protein involved Alzheimer's disease from building up in the brain. They found that in test tube studies the molecule not only prevents the protein from forming clumps but can also reverse this process...
