HARI SREENIVASAN: Egyptian President Mohammed Morsi called out the military today, ahead of next weekend's referendum on a new constitution. Opposition forces say the document will enshrine the power of Islamists and curb human rights. Security forces were deployed today near the presidential palace, where protesters remain camped out. They said it's not enough that Morsi rescinded decrees that granted him near-absolute power.
HESHAM EZAT, Egyptian protester (through translator): The new constitutional declaration canceled the first one, but at the same time, it contained the same statements as the previous one. He is playing with us and trying to gain time until the referendum. We understand that. And nothing changes our position, because we know he hasn't changed anything.
HARI SREENIVASAN: The anti-Morsi faction has organized a new round of mass protests for tomorrow. Meanwhile, Morsi's Islamist supporters are planning a rival demonstration of their own.

Britain will become the first country to try to map the genetic code of thousands of cancer patients. The government said today it is setting aside $160 million for the project over three to five years.
We have a report from Lawrence McGinty of Independent Television News.
LAWRENCE MCGINTY: Frances Howell had breast cancer two years ago. After treatment, she told me she's now fine. But genetic tests show she has a gene called BRCA, which means the cancer would almost certainly come back. She decided to have her ovaries and breasts removed to stop it returning. Genetic testing had saved her life.
The prime minister was today banging the drum for even more genetic testing that will analyze all the genes of 100,000 cancer patients like Frances to build up a DNA database. Scientists first decoded the three billion bits of DNA in the human genome 12 years ago, making it possible to tailor drugs for individual patients.
DR. JAMES BRENTON, cancer researcher: Being able to say to the lady in front of us in the clinic, we know from the bar code in your cancer that you will respond to this treatment, but not to this treatment. And that is a very important thing, because we have treatments that work for some of our patients, but we really need to have tests that really can choose the right treatment for the right person at the right time.
LAWRENCE MCGINTY: But it's not just tailoring drugs for individual patients. Researchers will be able to use the DNA database to look for new cancer genes. Finding them should allow scientists to develop new treatment.
HARI SREENIVASAN: The project has raised privacy concerns, but Prime Minister Cameron's office said participation is voluntary, and the data will be made anonymous before it is stored.
