telomerase - the enzyme capable of immortalizing human cells. They developed small synthetic inhibitors against telomerase that when introduced into human cancer cells caused progressive telomere shortening and eventually cell death.

to begin collecting DNA samples from Iceland's 270,000 citizens and linking the genetic profiles with their health records and family trees. The database it plans to build would offer an unprecedented chance to discover genetic links to disease - and an unprecedented danger to privacy, doctors and researchers attending a packed meeting of the American Society of Hematology said Sunday.
*Data derived from a balloon-borne probe of the early Universe provides
strong evidence that the Universe is flat and not open. The data is also consistent with the idea that a force, very possibly the theorized cosmological constant, a form of countergravitational "dark energy" thought to fill the universe, is helping drive the never-ending expansion of the Universe.

*Gene therapy yields super pigs. But will they fly with the public? Here
come the super pigs. Medical researchers using gene therapy have figured out a way to make young hogs grow 40 percent larger and faster. Scientists say the technique, which stimulates production of the pigs’ growth hormones, would be a boon for livestock farmers — and eventually could even be used to treat children with growth problems and to prevent muscle deterioration in AIDS and cancer patients.

*Quantum gravity presents the ultimate challenge to theorists. Physics in
the 20th century is founded on the twin pillars of quantum mechanics and the theory of relativity. However, in spite of the enormous successes of each theory individually, the two appear to be incompatible.

*Structure of Molecular Scissors Critical for the Shaping of Cells Revealed
by Structural Biologists at The Salk Institute. The living cell is the prototypical shape-shifter. At any given moment, it will reorganize itself to move, grow, replicate and even die.To achieve its Gumby-like existence, the cell's internal protein scaffolding, its cytoskeleton, is split apart and put back together ... over and over again. Until recently, little was known about how this basic life process was accomplished on the molecular level. But now scientists at The Salk Institute have shown in three-dimensional detail how remodeling begins in one of the most prevalent of these cytoskeletal proteins, called actin.

*So I'm happy to pass on the findings of a report on likely developments in
health care over the next decade, HealthCast 2010, prepared by PricewaterhouseCoopers (PwC), the chartered accountants and management consultants. It's an international study, based on interviews with 400 ''thought leaders'' and health care executives in many developed countries, including Australia. Most attempts to peer into the future of healthcare emphasise the effects of aging and the growing cost of medical technology. But this report highlights three other forces of change: more demanding consumers, the impact of the information revolution, and the way ''genomics'' will shift health care from cure to prevention.
