Track Watebirds Using Nuclear Physics

Nuclear physics used to track australian waterbirds. Australia's native birds are on the decline - those damn humans! Yes, we are destroying the planet and we have to do something about it.  Obtaining data on bird numbers is paramount. Nuclear physics is the answer.  Researchers are examining feathers recently dropped by waterbirds. It provides information on where birds have been and what they have eaten.  The I-TRAX Core Scanner shows chemical changes over time. A mass spectrometer is also used to determine oxygen, hydrogen and nitrogen isotopes. Feathers are composed of keratin like hair. Water sources have different chemical composition. This is stored in the keratin, so a map can be created of where birds have been living. The method of feather analysis is much cheaper than leg banding or satellite tracking. Members of the public can contribute. At present scientists are picking up feathers then posting them to the Australian Nuclear Science and Te...

A New Discovery on Immunity by Australian Scientists

Acclaim is given to two Australian scientists, Walter and Eliza Hall, who have changed ideas about the memory of the immune system. B cells make antibodies to fight infection. These cells do not die after doing their job and this is not the normal run of things. A pro-survival proteins is responsible for the cells' continuing existence. It has been proven that the Mcl-1 protein does this, not the Bcl-xL protein as was accepted in the past. Tests blocked the activity of Bcl-xL which showed that Mcl-1 stopped apoptosis - death. Cancer cells survive due to Mcl-1, so there are new possibilities for cancer research. It could also have repercussion for future treatment of the resistance response in organ transplant patients.
