During spatial learning, space is represented in the hippocampus through plastic changes in the connections between neurons. Jozsef Csicsvari and his collaborators investigate spatial learning in rats using the cheeseboard maze apparatus. This apparatus contains many holes, some of which are...
It takes a lot to make a memory. New proteins have to be synthesized, neuron structures altered. While some of these memory-building mechanisms are known, many are not. Some recent studies have indicated that a unique group of molecules called microRNAs, known to control production of proteins...

A high dietary intake of phosphate promotes tumor formation in an animal model of skin cancer, researchers at Emory University School of Medicine have found. The results, published in the journal Cancer Prevention Research, suggest that a high intake of phosphates may promote tumor development...
Inappropriate activation of the blood clotting process inside a blood vessel results in the formation of a clot known as a thrombus. Thrombus formation in blood vessels in the brain and heart can lead to stroke and heart attack, respectively. Drugs that prevent blood clot formation reduce the...

...the future? need to put these in order:
1- the star shrinks and forms a white dwarf
2-a cloud of gas is pulled together
3-nuclear reactions start inside the protosun
4-hydrogen fuses to form helium
5-the red giant uses up all the helium
6-the hydrogen is used up and the star becomes a red giant
