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...

Can science rescue coral reefs?

Reef research: Aerial view of the Hawai’i Institute of Marine Biology on Coconut Island, which is surrounded by coral reefs that provide study material for research into the stress resilience of corals. (Photo: Doug Peebles.) It’s not easy being a coral in the ocean. The complex lifestyle of the polyps and their algal symbionts depends on a range of parameters being just right, including sunlig...

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.
