Stressed Reefs May Get Relief

is it that is not poison? All things are poison and nothing is without poison. It is the dose only that makes a thing not a poison. Coral reefs, already one of the most delicate marine systems, are threatened by a host of pressures, including sea temperature increases , pollution, development, fishing, and tourism. Last March, the U.S. government unveiled an ambitious plan that addresses the mo...

When cells get stressed: an integrative view of cellular senescence.

Cells entering a state of senescence undergo a permanent cell cycle arrest, accompanied by a set of functional and morphological changes. Senescence of cells occurs following an extended period of proliferation in culture or in response to various physiologic stresses, yet little is known about the role this phenomenon plays in vivo. The study of senescence has focused largely on its hypothesiz...

Research Chimpanzees May Get a Break

A recent report by the Institute of Medicine leaves few urgent reasons standing for the continued use of chimpanzees in biomedical research. It is high time to think about their retirement, Frans de Waal argues, without neglecting prospects for non-invasive research on behavior, cognition, and genetics.

Elderly chimps may get Alzheimer's disease.

Symbiont diversity may help coral reefs survive moderate climate change.

Given climate change, thermal stress-related mass coral-bleaching events present one of the greatest anthropogenic threats to coral reefs. While corals and their symbiotic algae may respond to future temperatures through genetic adaptation and shifts in community compositions, the climate may change too rapidly for coral response. To test this potential for response, here we develop a model of ...
