Bamboos are a diverse group of evergreen perennial flowering plants in the subfamily Bambusoideae of the grass family Poaceae. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent.

There are two principal reasons for including some knowledge of history among the recommendations. One reason is that generalizations about how the scientific enterprise operates would be empty without concrete examples. Consider, for example, the proposition that new ideas are limited by the context in which they are conceived; are often rejected by the scientific establishment; sometimes spring from unexpected findings; and usually grow slowly, through contributions from many different investigators. Without historical examples, these generalizations would be no more than slogans, however well they might be remembered. For this purpose, any number of episodes might have been selected.
To develop drugs that effectively combat metastasis, it's fundamentally important to understand what directs the metastatic process, Sun said. Collagen is a protein that serves as the primary component of human connective tissue, which supports, protects and provides structure for other tissues and organs in the body. Collagen is also a key part of the extracellular matrix, the non-cellular part of tissues and organs that acts as a scaffold and also performs important biochemical and biomechanical functions. In the era of precision medicine, we think taking into account the physical properties of a patient's tissue can be critical for the prediction and treatment of metastatic disease. The correlation is due to a cellular phenomenon known as "contact guidance," which is analogous to a back-country hiker trying to pick a route based on the contours of the terrain and the network of downed trees on the ground.
Hearing the words "new species discovered" may conjure images of deep caves, uncharted rainforests, or hidden oases in the desert. But the reality is that thousands of new species are discovered each year by enterprising scientists all over the world. Many of these new species do come from exotic locations, but more surprisingly, many come from just down the road, including the newest member of the Hokie Nation, the millipede Nannaria hokie. Since then, the critter has been found at the area commonly referred to as stadium woods and in town in Blacksburg as well. Nannaria hokie pronounced nan-aria ho-key is about 2 centimeters long, and a dark reddish millipede with yellow-white highlights apologies to those who thought it would be maroon and orange.
