Scientists discovered that cells can distinguish themselves from closely related competitors through the use of a virus, and the harboring of phage in bacterial genomes benefits host cells when facing competitors in the environment.

Scientists have uncovered a process in cells that prevents DNA from becoming tangled, which resembles a method used to control climbers' ropes.

Obesity can break down our protective blood brain barrier resulting in problems with learning and memory, scientists report.

Many people fighting a very aggressive form of acute myeloid leukemia (AML) don't survive more than five years. These very sick patients are often unable to receive the only cure -- a bone marrow transplant. Now, an international team of scientists report in Nature Cell Biology on a long-overlooked part of a leukemic cell's internal machinery, where they may have found a key to treating the aggressive blood cancer.

NTU Singapore scientists have developed a sustainable way to demonstrate a new genetic modification that can increase the yield of natural oil in seeds by up to 15% in laboratory conditions.

What will a three-degree-warmer world look like? When experiencing stress or damage from various sources, plants use chloroplast-to-nucleus communication to regulate gene expression and help them cope. Now, Salk Institute researchers have found that GUN1 -- a gene that integrates numerous chloroplast-to-nucleus retrograde signaling pathways -- also plays an important role in how proteins are made in damaged chloroplasts, which provides a new insight into how plants respond to stress.
