good morning to you. thank you for being with us. 6:00 a.m. in new york this morning. tuesday, july 19th. i was hearing that in parts of iowa the heat index felt like 130 yesterday. it s been brutal out there. even this morning on the east coast, it felt different. it felt hotter. we ll be covering that. we re watching that and millions are watching with a worldwide media empire hanging in the balance rupert murdoch is just hours away from facing his defining moment. in less than four hours, murdoch, his son and former top newspaper executive will appear before the british parliament. they will be asked what they knew about this phone hacking scandal that s growing wider by the day. it s threatening to take down news corp and perhaps murdoch himself. and the question is what they are going to be called upon to explain, what they re going to be compelled to explain and how that s different from being called before congress. who is going to be asking the questions today
remain blissfully ignorant. how well is our understanding of it improving? i think we ve made enormous strides in terms of understanding alzheimer s disease. we know that there are several proteins involved. we know the cells are dying. we know that the clearance of the protein is reduced. we have new tests that can show us the protein abnormalities in the brain. we re making definite strides in terms of the new therapeutics that are emerging. we don t know enough. we need a lot more research. but we re really making progress. to change that researchers are studying segments of the population to see how they age, to uncover clues to see what causes alzheimer s in some but not others. dr. peterson of the mayo clinic. a great deal of research right now on alzheimer s disease is focusing on imaging tests such as mri scans, p.e.t. scans, even p.e.t. scans that can pick up the protein in the brain that s thought to be responsible for the disease as well as other biomarkers.
