'Underground' tunnels discovered as means for communication between immune system cells

...notubules, structures that were first described in fruit flies in 1998, and subsequently, identified in a handful of different types of animal and human cells. "It's one thing to find that this intricate physical network exists but quite astonishing to learn that immune system cells are using it to relay ...

Birds and bats sow tropical seeds

... in nearby forests will fly to the bait to eat the fruit and will likely drop seed from forest species they carried. Fruit will be available all year, so a seasonal progression of seeds from longer-living deep forest species should be carried with the bats and birds. Other tracts will be planted with wind-...

Micro RNAs play role in egg making

... Carnegie Mellon, the scientists compared maturing fruit fly eggs. One group of eggs was missing a gene essential for producing miRNAs, whereas another group of eggs had normal miRNA production. (All plants and animals have DICER, the gene the produces miRNAs, so the researchers used a "genetic trick" to g...

"It's thought that plants may abort some of their seeds, especially under stress, to conserve and divert resources to the remaining seeds.
