Washington, March 27 : Duke University researchers have devised a new MRI signalling method that can help see such molecular changes inside the body as may signal health problems like cancer.

Warren Warren, James B. Duke Professor of chemistry at Duke, says that the novel method makes more of the body''s chemistry visible by MRI.

When used for brain imaging, MRI enlist the hydrogen atoms in water to create a graphic display in response to magnetic pulses and radio waves.

Washington, March 27 : A new study by a Queen’s University Belfast academic has shown that crabs not only suffer pain but that they retain a memory of it.

The study, which looked at the reactions of hermit crabs to small electric shocks, was carried out by Professor Bob Elwood and Mirjam Appel from the School of Biological Sciences at Queen’s.

Professor Elwood, who previously carried out a study showing that prawns endure pain, said his research highlighted the need to investigate how crustaceans used in food industries are treated.

Washington, Mar 27 : A team of researchers at Mount Sinai School of Medicine and the UC Davis Center for Biophotonics Science and Technology has made a breakthrough in understanding how HIV spreads through the human body after capturing the process on camera.

Researchers have recorded the transfer of human immunodeficiency virus (HIV) from infected to uninfected T cells through structures called virological synapses.

The breakthrough study could lead to new methods to block the transmission of HIV, and shows that cell-to-cell may be the predominant mode of HIV transmission in the body.
