Researchers identify key pathway for plant cell growth
For plants, the only way to grow is for cells to expand. Unlike animals, cell division in plants happens only within a tiny region of the root and stem apex, making cell expansion the critical path to increased ...
Ultraviolet protection molecule in plants yields its secrets
Lying around in the sun all day is hazardous not just for humans but also for plants, which have no means of escape. Ultraviolet (UV) radiation from the sun can damage proteins and DNA inside cells, leading ...
Improving crop yields in a world of extreme weather events
Farmers in the United States witnessed record-breaking extremes in temperature and drought during the last two summers, causing worldwide increases in the costs of food, feed and fiber. Indeed, many climate ...
Computer model used to pinpoint prime materials for efficient carbon capture
When power plants begin capturing their carbon emissions to reduce greenhouse gases and to most in the electric power industry, it's a question of when, not if it will be an expensive undertaking.
The last survivors of the end of the world
(Phys.org) —In 2 billion years' time, life on Earth will be confined to pockets of liquid water deep underground, according to PhD astrobiologist Jack O'Malley James of the University of St Andrews. The ...
New models predict drastically greener Arctic in coming decades
Rising temperatures will lead to a massive "greening" of the Arctic by mid-century, as a result of marked increases in plant cover, according to research supported by the National Science Foundation (NSF) ...
Using math models to make predictions: How vegetation competes for rainfall in dry regions
The greater the plant density in a given area, the greater the amount of rainwater that seeps into the ground. This is due to a higher presence of dense roots and organic matter in the soil. Since water is ...
IBM offers glimpse into the future (w/ Video)
Air-powered batteries, 3-D cellphones that project holographs and personalized commutes are among the predictions of IBM scientists gazing into their crystal balls.
Climate-driven heat peaks may shrink wheat crops
More intense heat waves due to global warming could diminish wheat crop yields around the world through premature ageing, according to a study published Sunday in Nature Climate Change.
Researchers reveal gas that triggers ozone destruction
Scientists at the Universities of York and Leeds have made a significant discovery about the cause of the destruction of ozone over oceans.
Model plant misled scientists about multicellular growth
Scientists have misunderstood one of the most fundamental processes in the life of plants because they have been looking at the wrong flower, according to University of Leeds researchers.
Accidental breakthrough on the puzzle of atmospheric acids
In a classic example of an accidental scientific breakthrough a University of Sydney research team may have solved the mystery of why there is more non-industrial acid in air than anyone can explain.
Scientists identify why some fathers are left holding the baby
A century old mystery as to why, for some animals, it's the father rather than the mother that takes care of their young has been cracked by scientists at the University of Sheffield and University of Bath.
The betrayal of the aphids
Aphids are devastating insect pests and cause great losses to agriculture worldwide. These sap-feeding plant pests harbor in their body cavity bacteria, which are essential for the aphids' fecundity and survival. ...
