Grow a tomato inside a square box, and you’ll end up with a square tomato. It’s an experiment that shows clearly how confinement can influence a body’s evolving shape.
If you brush against the wings of a butterfly, you will likely come away with a fine sprinkling of powder. This lepidopteran dust is made up of tiny microscopic scales, hundreds of thousands of which ...
Flipping a metabolic switch to slow tumor growth（图）
Flipping metabolic switch tumor growth
2020/8/27
An enzyme can be used as a metabolically responsive "switch" that decreases tumor growth, according to a new study. The findings are published in the journal Nature.By restricting the dietary ami...
Where'd you get those genes? Individual growth can vary wildly when populations interbreed（图）
genes Individual growth vary wildly populations interbreed
2020/3/20
Scientists at Scripps Institution of Oceanography at the University of California San Diego have discovered why some hybrids between populations of the same species don't develop as well as others. Th...
Urbanization delays spring plant growth in warm regions（图）
Urbanization delays spring plant growth warm regions
2019/11/22
The first appearance of bright green leaves heralds the start of spring, nudging insects, birds and other animals into a whirlwind of action. But a new NSF-funded study shows that urbanization shifts ...
North Carolina coastal flooding is worsening with climate change, population growth（图）
North Carolina coastal flooding worsening climate change population growth
2019/10/22
A historic 120-year-old data set is allowing researchers to confirm what data modeling systems have been predicting: climate change is increasing precipitation events like hurricanes, tropical storms ...
Shining a Light on Plant Growth and Development（图）
Shining a Light Plant Growth Development
2017/12/19
Plants don’t have eyes, but they do “see” their surroundings using light.That’s made possible by proteins called photoreceptors that absorb light and convert it into a signal that turns genes on or of...
From Alaska To Amazonia:First Global Maps Of Traits That Drive Vegetation Growth（图）
Alaska Amazonia:First Global Maps Drive Vegetation Growth
2017/12/19
Based on measurements of 45,000 individual plants from 3,680 species, and using high-tech statistical mapping protocols, the team created global maps of plant traits including leaf nitrogen concentrat...
Researchers develop equation that helps to explain plant growth（图）
Researchers equation plant growth
2017/3/30
It is rare in biology that a single trait can answer questions spanning several fields of research. One such trait is plant biology’s “leaf mass per area,” a simple measurement calculated by weighing ...
Rapid trait evolution crucial to species growth, CU Boulder study finds
Rapid trait evolution species growth CU Boulder
2017/2/16
Rapid evolution at the edges of a given species habitat may play a larger role in population expansions than previously suspected, according to the results of a new University of Colorado Boulder-led ...
Gene network controls how many flowers and fruits plants will produce during critical growth window
Gene network controls flowers and fruits plants critical growth window
2016/11/29
There is staggering diversity in the number of flowers produced by each of the 2,800 or so species of plants in the nightshade family, which includes economically important crops such as tomatoes, pep...
Microchip enables fast,precise measurement of single-cell growth
Microchip fast precise measurement single-cell growth
2016/9/12
A new technique invented at MIT can precisely measure the growth of many individual cells simultaneously. The advance holds promise for fast drug tests, offers new insights into growth variation acros...
Stanford biologists crack centuries-old mystery of how cell growth triggers cell division
Stanford biologists centuries-old mystery growth triggers cell division
2015/10/13
Cells were discovered in 1676, and almost immediately afterward scientists began wondering why cells are so perfectly small.More than three centuries later, a team of Stanford biologists have zeroed i...

Invisible helpers of the sea Marine bacteria tiny ocean algae
2015/6/18
A glass of seawater is teeming with life, and a recent expedition revealed more about what ocean water contains. Microscopic creatures in the world’s oceans weigh more than all of the fish i...
Modern biology has attained deep knowledge of how cells work, but the mechanisms by which cellular structures assemble and grow to the right size largely remain a mystery. Now, Princeton University re...
