Plants as biomonitors of heavy metals
There are many sources of heavy metal pollutants, including vehicle exhausts, various industries, mines, thermal plants, and other combustion processes, and even volcanic activity. The presence of heavy metals in the environment represent a health ri.....»»
Are plants and fungi trading carbon for nutrients? Not likely, say researchers
Every year, plants move 3.58 gigatons of carbon to mycorrhizal fungi, their underground partners—enough, in fact, that if it were ice, it would cover 112 million NHL hockey rinks. However, a dominant scientific theory explaining that huge transfer.....»»
Pollination shifts in Caribbean after Hurricane Maria demonstrate ecological resilience
Most flowering plants depend on animals for pollination. In warm wet tropical regions, more than 90% of plant species are pollinated by animals. In Dominica, a Caribbean island country, researchers have identified a mutualistic relationship between t.....»»
Q&A: Extreme weather is disrupting lives in southern Africa—new policies are needed to keep the peace
Over the past decades, heavy and more frequent rainfall and dry spells in southern Africa have caused loss and damage to agriculture, livestock, the energy sector, food security and nutrition......»»
For the first time since 1882, UK will have no coal-fired power plants
A combination of government policy and economics spells the end of UK's coal use. Enlarge / The Ratcliffe-on-Soar plant is set to shut down for good today. (credit: Ashley Cooper) On Monday, the UK will see the closure o.....»»
59 dead in Nepal as downpours trigger floods
Floods and landslides triggered by heavy downpours in Nepal killed at least 59 people across the Himalayan country, with rescue teams searching for 44 missing, police said Saturday......»»
Elucidating the mechanism of cell division during plant self-healing
When the stem of a plant is injured, the surrounding cells proliferate to repair and fuse the damaged tissue, eventually restoring function. This self-healing property is utilized in grafting techniques to propagate fruit and vegetable plants......»»
Rocket Report: SpaceX salvages Starship wreckage; pessimism for Virgin Galactic
The penultimate flight of Japan's workhorse H-IIA rocket deploys a spy satellite. Enlarge / A salvage ship raises a portion of SpaceX's Super Heavy booster from the Gulf of Mexico. This booster was used on the most recent Starshi.....»»
Presence of bacteria in soil makes flowers more attractive to pollinators, study shows
Bacteria that live in soil and help roots fix nitrogen can boost certain plants' capacity to reproduce, according to an article published in the American Journal of Botany describing a study of this mechanism in Chamaecrista latistipula, a legume bel.....»»
Bulrush once kept NZ"s wetlands and lakes thriving—now it could help restore them
With about 90% of New Zealand's natural wetlands drained or severely damaged during the past decades, we need to understand the role of native plants in the restoration of these important habitats......»»
Injecting manure into growing cover crops can cut pollution, support corn crops
Nitrogen in the soil, where plants can readily utilize it, benefits crop growth and health. However, nitrogen leaving the soil—whether through leaching into the groundwater table, flowing with surface runoff into streams or escaping into the air as.....»»
New fossil species reshapes understanding of grape family history
Until now, it was believed that plants of the grape family arrived at the European continent less than 23 million years ago. A study on fossil plants draws a new scenario on the dispersal of the ancestors of grape plants and reveals that these specie.....»»
Advancing synthetic Ephedra-type alkaloids with a two-step enzymatic approach
Ephedra-type alkaloids, a class of naturally occurring compounds derived from plants in the genus Ephedra, have long held interest in the pharmaceutical industry due to their stimulant and airway widening effects. These alkaloids are used for the tre.....»»
Strategies for maximizing recombinant protein production in tobacco plants
Plant molecular farming (PMF) is a modern, sophisticated technology that utilizes plants' biosynthetic machinery to synthesize a plethora of recombinant proteins, including industrial and therapeutic enzymes. It has several advantages over traditiona.....»»
How a nearby supernova left its mark on Earth life
When a massive star explodes as a supernova, it does more than release an extraordinary amount of energy. Supernovae explosions are responsible for creating some of the heavy elements, including iron, which is blasted out into space by the explosion......»»
Sustainable metal-recycling method reduces cost and greenhouse gas emissions
A research team led by Rice University's James Tour has developed a method to recycle valuable metals from electronic waste more efficiently while significantly reducing the environmental impact typically associated with metal recycling......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Thousands of abandoned mines in Colorado are leaking toxic water, but Congress finally has a solution in sight
Polluted water leaking from thousands of abandoned mines in Colorado's mountains is turning wetlands orange and dumping toxic dissolved metals in the headwaters of many of the state's rivers......»»
Deadly flooding in Central Europe made twice as likely by climate change
Human-caused climate change doubled the likelihood and intensified the heavy rains that led to devastating flooding in Central Europe earlier this month, a new flash study found......»»
Extreme botany: Paramotorists soar across remote Peru desert to collect threatened plants
In an innovative paper published today in the journal Plants, People, Planet, scientists from the Royal Botanic Gardens, Kew, Huarango Nature and paramotorists from Forest Air, highlight the exciting potential of paramotoring as a means of aiding res.....»»
Scientists explore how indoor vertical farming could help future-proof food demand
To make sure everyone eats well in our crowded world, we need to innovate. Vertical farming systems, which grow plants intensively in an indoor setting, could be part of the answer—but to use them on a large scale we need to overcome key problems,.....»»
