Brown team finds crucial protein role in deadly prion spread

...n of existing prion complexes. Once converted, the thinking goes, clusters of "bad" or infectious protein are smashed into smaller bits, a process that creates "seeds" so that prions multiply more quickly in the body. Hsp104, a molecule known to be required for prion replication, could function as this protei...

100 percent juices found as beneficial to health as fruits and vegetables

... a European study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables. Juices are comparable in their ability to reduce risk compared to their whole fruit/vegetable count...

Novel laboratory technique nudges genes into activity

... 2005, demonstrates a shift away from conventional thinking about how gene expression is naturally controlled, as well as how scientists might be able to exploit the process to develop new drug targets, Dr. Corey said. For example, current methods to block gene expression, such as RNA interference, rely on...

MRSA toxin acquitted: Study clears suspected key to severe bacterial illness

... France, decided to test the PVL virulence theory, thinking that if they could understand the role of this toxin in disease, they could more quickly diagnose serious cases and develop effective treatments. In addition to observing the destruction of human white blood cells regardless of whether PVL was pre...

Math model predicts cancer behavior

...uaranta and Cummings expect to see this new way of thinking sweep through biology. "Particularly in cancer biology, we know so much about tumors, but we can do so little: why is that"" Quaranta said. "I think the reason is that we need additional tools, and those are the tools of mathematics." The team's ...

Cracking the egg

...ikov at The Jackson Laboratory have certainly been thinking about this topic for years. A new paper in the journal Genes & Development presents significant new information about what is happening within a fully grown (pre-ovulatory) egg and some of the changes that occur during transition to the two-cell ...

Heart smart: new drug improves blood flow

...tre at Monash with the aim of challenging orthodox thinking on heart disease and stroke. "Vascular diseases are the number one cause of death worldwide. Yet we don't know enough about the causes to reliably identify and treat cases, let alone prevent these diseases," he says. "In up to 95 per cent of cases,...

Researchers develop technologies to devour food pathogens

...t's not what we want," Linton said. "We are always thinking in terms of, 'Will this work for industry?' In this case, I believe the answer is yes. I would like to see this technology used regularly by industry in a couple years from now." Both technologies have the potential to help prevent food-borne illne...

Plants give up answers in the war on bacteria

Why do insects like to eat some plants more than others?

... evolution of plant allocation strategies. Current thinking on the subject says that these strategies are a trade-off between current reproduction and future survival. The finding that plant reproductive allocation can attract enemies means that sex may be even more costly than previously though. This researc...

"If you're feeling sleepy on your way over the river and through the woods to grandmother's house, it's much better to pull ...

Does natural selection drive the evolution of cancer?

... emerging cross-disciplinary field that brings the thinking of ecologists and evolutionary biologists to bear on cancer biology. Insights from their work may have profound implications for understanding why current cancer therapies often fail and how radically new therapies might be devised. A review by ...

Reading Shakespeare has dramatic effect on human brain
