Down syndrome: It's not just the age factor
...irth to a child with Down Syndrome is not simply a matter of how old she is. Although it is a fact that as women get older, they are more likely to have a child with Down Syndrome, other factors also play a role. According to Markus Neuhuser and Sven Krackow, from the Institute of Medical Informatics, Bio...Natural anti-viral enzyme helps keep cancer cells alive, researchers find
...s not been previously seen. It's a straightforward matter to block the action of TBK-1, so this might be a promising avenue for new cancer treatments, Dr. White said. Because that would also interfere with the body's immune function, however, a balance would have to be found between killing cancer cells and...Can further studies lower the cost of preserving vision?

I think there are going to be multiple different failures, and that the loss of stem cells can play a role in a number of them."

"The holes are made by mechanical interaction with the collapsing bubbles," said...Why are there so many weeds in your garden this year?
Some years, no matter how diligently you pull, your backyard garden is always covered with weeds. Other years, with the minimum of effort, your garden remains weed-free.

Remarkably, no matter what sour compounds they fed the mice, nerve signals from the taste cells remained absent; the animals were completely insensitive to all kinds of acids.
