Cellular identity is defined by gene activity that drives intercellular communication and is pivotal to understand mechanisms underlying multicellular organisms. In a new report Abbas Ghaddar and a research team in biology, ...
A small international team of molecular and evolutionary scientists has discovered that male yellow crazy ants (also known as long-legged ants) have two sets of DNA throughout their bodies. In their paper published in the ...
Mechanical engineers at Duke University have demonstrated a set of prototypes for manipulating particles and cells in a Petri dish using sound waves. The devices, known in the scientific community as "acoustic tweezers," ...

(Phys.org)—Cell migration is an intrinsic feature of multicellular organisms, enabling such processes as embryo development, wound healing, and immune responses. These activities require cells to move freely within tissues. ...
(Phys.org)—For a long time, biologists have considered sex to be an inherent trait of multicellular life, while microbial eukaryotes were considered to be either optionally sexual or purely clonal. From this perspective, ...
(Phys.org) —A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago ...
