PHILADELPHIA— Being the top dog — or, in this case, the top gelada monkey — is even better if the alpha male is willing to concede at times to subordinates, according to a study by researchers from the University of Pennsylvania, the University of Michigan and Duke University.
Alpha male geladas who allowed subordinate competitors into their group had a longer tenure as leader, resulting in an average of three more offspring each during their lifetimes.
Most visitors to the Caribbean hope that their stay won’t coincide with a major tropical storm.
Hyejung Lee hoped for exactly the opposite.
PHILADELPHIA — Researchers are hopeful that new advances in tissue engineering and regenerative medicine could one day make a replacement liver from a patient’s own cells, or animal muscle tissue that could be cut into steaks without ever being inside a cow. Bioengineers can already make 2D structures out of many kinds of tissue, but one of the major roadblocks to making the jump to 3D is keeping the cells within large structures from suffocating; organs have complicated 3D blood vessel networks that are still impossible to recreate in the laboratory.
