Scientists find cell surface enzyme matriptase causes cancer
... a strong and versatile pro-growth signal that can travel
along more than one route to the cell nucleus," said Dr. Karin List, the other lead author and an NIDCR scientist. "But the key point is, like a classic oncogene, matriptase initiates the erroneous growth signal. As further confirmation of this, w...
Ships bring alien jellyfish invaders to our shores
... 3,000 species of marine organisms are believed to travel
the world in ships' ballast water each day. Ships take in water for stability before a voyage and despite preventative measures such as mid-ocean exchange/flushing this 'foreign' water and its contents can find their way into bays and harbours at the...
Long sought-after flowering signal found
...oncluded that a signal that induces flowering must travel
from the leaves to the site where flowers are initiated. Despite these early findings, little progress has been made in pinpointing the hypothetical flower-inducing substance, dubbed florigen. These difficulties have led many scientists to believe th...
New imaging technology shown to detect pancreatic inflammation in type 1 diabetes
...se MNPs, which are minute particles of iron oxide, travel
through the blood vessels of the body including the pancreas. If pancreatic vessels have become leaky from inflammation, the magnetic particles spill into nearby tissues, where they are "eaten" by scavenger cells called macrophages. Thus, the MNPs be...

When cave crickets go out for dinner, they really go, researchers say
CHAMPAIGN, Ill. -- Cave crickets travel
farther from their homes to forage -- by about double -- than their previously reported range, researchers have discovered. In Texas, that means protective buffer areas around caves may need to be extended to protect endangered invertebrate species t...
Scavenger cells could be key to treating HIV-related dementia
...HIV-infected macrophages in the brain continuously travel
to the temporal lobe, a part of the brain Alzheimer's disease often damages. Because the virus mutates nearly 100 times faster in the temporal lobe than other parts of the brain, attacking macrophages migrate there in a constant stream, causing harmf...
