Carbon taxes could create new winners and losers among countries, research says Posted: 19 Feb 2019 12:52 PM PST A global carbon tax would create new sets of economic winners and losers, with some countries holding a distinct competitive advantage over others, according to new research. |
Prenatal forest fire exposure stunts children's growth Posted: 19 Feb 2019 12:51 PM PST Forest fires are more harmful than previously imagined, causing stunted growth in children who were exposed to smoke while in the womb, according to new research. |
Posted: 19 Feb 2019 10:29 AM PST When compressed, a material typically becomes a better conductor of heat. Not so for the unusual material cubic boron arsenide, which when under pressure shows its conductivity first improves and then deteriorates. The findings not only hint at future applications, but proffer a theory that may offer insights into some of the oldest Earth processes. |
Renewable energy generation with kites and drones Posted: 19 Feb 2019 10:27 AM PST A group of researchers has recently developed a new software aimed at the analysis of energy generation systems based on kites and drones. They used the software to study the behavior of these systems while transforming the kinetic energy of the wind into useful electrical energy. |
Plants can skip the middlemen to directly recognize disease-causing fungi Posted: 19 Feb 2019 10:26 AM PST Scientists have revealed that direct physical associations between plant immune proteins and fungal molecules are widespread during attempted infection. The authors' findings run counter to current thinking and may have important implications for engineering disease resistance in crop species. |
Fishing and pollution regulations don't help corals cope with climate change Posted: 19 Feb 2019 08:18 AM PST A new study reports that protecting coral reefs from fishing and pollution does not help coral populations cope with climate change. The study also concludes that ocean warming is the primary cause of the global decline of reef-building corals and that the only effective solution is to immediately and drastically reduce greenhouse gas emissions. |
Why North Carolinian boats are fishing off New Jersey's coast, and how a CSF might help Posted: 19 Feb 2019 08:18 AM PST By studying the logbooks of fishing boats, researchers found that some fishing boats travel more than 250 miles to catch the fish that used to be in local waters. In response, researchers began investigating how local community supported fishery programs -- like farm shares for fish -- can affect fishing communities. That resulted in the creation of Fishadelphia, a CSF based in a South Philadelphia charter school. |
Ocean acidification harms cod larvae more than previously thought Posted: 19 Feb 2019 08:17 AM PST The Atlantic cod is one of the most important commercial fish species in the world. Recent studies have shown that ocean acidification threatens the early life stages of this species. So far it was hoped that at least the larvae that survive might be more robust and therefore may aid in the adaptation of this population. A new article suggests otherwise. |
The global impact of coal power Posted: 19 Feb 2019 08:17 AM PST With data and modelling from almost 8,000 coal power plants, researchers present the most comprehensive global picture to date of climate and human health impacts from coal power generation. |
Forest fires as an opportunity for ecosystem recovery Posted: 19 Feb 2019 08:17 AM PST It is estimated that globally there are more than two million hectares of land in need of restoration. The fires that occurred in those places provided the people who manage them with an opportunity to change, via a suitable process of ecological restoration, the previous bad forestry practices. |
Total synthesis of marine antitumor agents trabectedin and lurbinectedin Posted: 19 Feb 2019 08:16 AM PST With its vast numbers of different lifeforms, the sea is a largely unexplored source of natural products that could be starting points for new pharmaceuticals, such as the antitumor drugs trabectedin and lurbinectedin. Because only tiny amounts can be obtained from sea organisms, synthetic production is necessary. Scientists have introduced a new, efficient synthetic route for these two drugs. A key step is the light-controlled activation of a carbon-hydrogen bond. |
Natural resources valued differently by men and woman Posted: 19 Feb 2019 08:16 AM PST Men and women value, access and use resources from the natural environment in distinct and different ways, a new study has shown. |
Climate-friendly labriculture depends on an energy revolution Posted: 19 Feb 2019 05:07 AM PST In a first-of-its-kind study, the climate-change impact of several production methods for lab-grown and farmed beef was assessed accounting for the differing greenhouse gases produced. The new projections reveal that over the long term, cultured meat production methods requiring large energy inputs could increase global warming more than some types of cattle farming if energy systems remain dependent on fossil fuels. |
World's biggest terrestrial carbon sinks are found in young forests Posted: 18 Feb 2019 12:31 PM PST More than half of the carbon sink in the world's forests is in areas where the trees are relatively young -- under 140 years old -- rather than in tropical rainforests, research shows. |
