(Phys.org)—In a new study, scientists have developed the microscale version of self-driving vehicles: a 5-μm spherical micromotor that autonomously navigates its way through micro-traffic along a micro-maze to reach its ...
(Phys.org) —No two biological cells are exactly the same. Even a small biopsied tumor sample contains cells with large variations in their proliferation rate, potential for metastasis, drug responsiveness, etc. However, ...
Research led by the Department of Earth and Planetary Sciences, McGill University, Canada, has found that human cells seem to follow a homeostasis pattern of cell size and count across the entire organism.
In the 1950s, the geneticist J.B.S. Haldane attributed the maintenance or persistence of the mutation responsible for anomalies in red blood cells commonly observed in Africa to the protection these anomalies provided against ...
