... in hand, the next steps will be to explore how it reacts with other chemicals and how it might be put to use. "Now that we have made it, we can use our imagination to discover the reactivity of the compound, the reasons for its stability, synthetic routes to other compounds like this one, and practical use...JCI table of contents, June 1, 2006

In a study appearing in the June issue of the Journal of Clinical Investigation, Howard Rockman and colleagues from the University of North Carolina applied interm...'Big Brother' eyes encourage honesty, study shows

It seems people were subconsciously cooperating with the honesty box when it featured pictures of eyes rather than flowers. They also say the findings show how people behave differently when they believe they are being w...Nano probe may open new window into cell behavior
...a group of cells communicates with other cells and reacts to a broad spectrum of complex biomolecules surrounding it. But even the most sophisticated tools currently used for studying cell communications suffer from significant deficiencies. Typically, these tools can detect only a narrowly selected group...Experimental RNA-based drug kills prostate cancer cells effectively and safely
... When that module binds to a cancer cell, the cell reacts by engulfing the entire drug molecule. With the drug now inside the cancer cell, the second module, which contains silencing RNA, launches its effect. The silencing RNA seeks out and binds to the RNA for a specific cancer-causing protein, called PL...Oxygen deprived brains repaired and saved
...the body tries to protect itself and how the brain reacts when it experiences mild, non-damaging hypoxia. "I found that mild, non-damaging hypoxia actually protected the brain against a subsequent injury by activating certain proteins," Dr Jones said. "Mild hypoxia appears to pre-condition neural tissue...Scientists uncover critical step in DNA mutation

...organs in each well, and see how each kind of cell reacts to the same dosage -- a quick way to detect a drug's potential side effects on the body. "The trick is to use one pump for everything, and control the fluid distribution though all the channels," Yang said. While he has worked out an initial design,...A new understanding of how cells defend themselves against bacterial pore-forming toxins
...ng a drop in its potassium concentration, the cell reacts by forming a multi-protein complex known as an inflammasome. Scientists know that inflammasomes act like a sort of roving security force inside the cell, detecting a variety of danger signals such as bacterial RNA or bits of bacterial flagellin.

When released into neural synapses, the copper damps down the activity of these antennas, called NMDA receptors. The activity of NMDA receptors determine...Changing length of days reverses how estrogen affects aggressiveness in mice
...t can play a very significant role in how estrogen reacts in mice," Trainor said. "If something as simple as the length of day can affect how estrogen is used in the body, at least in some species, how are other environmental factors such as diet affecting estrogen in humans? It is something we don't know...Bacteria that use radiated water as food
