Researchers at the University of Toronto and Mount Sinai Hospital have identified a protein that plays a critical role in the regulation of “natural killers cells” in the immune system’s battle against foreign and diseased cells.

“Our research is a small part of the larger problem of how viruses and diseased cells ravage the body and circumvent our immune system,” says Kathleen Binns, a U of T doctoral student in medical genetics and microbiology and an author on a paper in the June 20

Three new varieties of tangerines – the TDE2, TDE3, and TDE4 – are the University of California’s most recent citrus varieties to be released for commercial production. The tangerines, which are complex hybrids, are siblings since they share the same parents. The varieties will be patented and eventually be given trademarked names. The three tangerines are large fruited compared to other varieties, have a sweet taste, and bear fruit with a deep orange rind.

“While the new tangerines share

The Russian astrophysicists have theoretically modelled coronal loop oscillations and have shown that the plasma present in coronal loops is quite “normal”. So, the puzzle of the Sun`s atmosphere heating remains unresolved.

Coronal loops, immense magnetic arches more hot and dense than the coronal gas, are formed by magnetic fields. They are anchored in the Sun`s visible surface rising up to 100 – 200 thousand kilometres. In the active regions of the Sun these loops, which are 1000 –

A lot of diseases are known to the medical science, each of the diseases having its own symptoms. Nevertheless, all diseases have something in common, regardless of the illness cause and the patients` individual reactions. These generalised regularities inherent in all diseases are called general pathology. Physicians can easily recognise anatomical and physiological abnormalities, but some symptoms are not evident. These abnormalities appear to be a presage of a disease, and after the recovery they

Physicists have to tread carefully when it comes to fertiliser, but the first tentative steps to a better understanding of the ancient art of fertilising the soil are described in a paper published today in the Institute of Physics publication, The Journal of Measurement Science and Technology.

Frederic Cointault, Philippe Sarrazin and Michel Paindavoine of the University of Burgundy in Dijon, France show how to take a snapshot of particles of fertiliser as a centrifugal spreader spits them

A manikin called Walter that can be used to test new clothes for extreme environments is described in research published today in the Institute of Physics publication Journal Measurement Science and Technology. Jintu Fan and Yisong Chen of the Institute of Textiles and Clothing at Hong Kong Polytechnic University, in Kowloon, explain in the journal how Walter`s special skin can simulate perspiration while his motorised limbs can be moved to make the manikin walk, for a more realistic test.
