Scientists study the evolutionary origins of coronary arteries
Coronary arteries are a vital part of the human heart, providing it with oxygen-rich blood so that it can work. By comparing the hearts of mammals, birds, reptiles, fish and frogs, a multi-institutional team of researchers ...

Biologists track DNA 'parasites' in the hunt for disease treatments
They are considered "parasitic genes." Even though they comprise over half of human DNA, much remains to be learned about them. Now University of California, Irvine biologists offer new insights into these entities known ...

Primate proteins evolve to guard against pathogens, study finds
Proteins on the surface of cells act as sentries—and microbes hoping to invade will evolve tricks to evade these front-line defenses. But the host cell's proteins don't sit back helplessly. They, too, can evolve in ways ...

Recent algae discovery gives clues to boost biofuel production
A new study from the Michigan State University-Department of Energy (DOE) Plant Research Laboratory (PRL) shows how some algae can protect themselves when the oxygen they produce impairs their photosynthetic activity. The ...

Polarity proteins shape efficient 'breathing' pores in grasses
Grasses have "respiratory pores" (called stomata) that open and close to regulate the uptake of carbon dioxide for photosynthesis on the one hand and water loss through transpiration on the other. Unlike many other plants, ...
