Scientists identify an enzyme that facilitates grafting between plants of different families
Scientists have found that the tobacco plant Nicotiana can maintain grafts between a broad range of species. Using Nicotiana as an intermediary, they succeeded...
Volcanic ash may have a bigger impact on the climate than we thought
When volcanos erupt, these geologic monsters produce tremendous clouds of ash and dust—plumes that can blacken the sky, shut down air traffic and reach...
The evolving chemistry of protoplanetary disks
Planets form from the gas and dust in disks that surround young stars. Chemicals in the disk that evaporate easily, called volatiles, include important...
Could there be a form of life inside stars?
Are we alone in the universe?
It is one of the most profound questions posed in modern astronomy. But although our understanding of the cosmos...
Nano-microscope gives first direct observation of the magnetic properties of 2-D materials
Australian researchers and their colleagues from Russia and China have shown that it is possible to study the magnetic properties of ultrathin materials directly,...
Single-atom-thin platinum makes a great chemical sensor
Researchers at Chalmers University of Technology, Sweden, together with colleagues from other universities, have discovered the possibility to prepare one-atom thin platinum for use...
In the Amazon, forest degradation is outpacing full deforestation
Deforestation in the Brazilian Amazon has increased abruptly in the past two years, after having been on a downward trajectory for more than a...
Researchers quantify worldwide loss of phosphorus due to soil erosion for the first time
Phosphorus is essential for agriculture, yet this important plant nutrient is increasingly being lost from soils around the world. The primary cause is soil...
Climate change will ultimately cost humanity $100,000 per ton of carbon, scientists estimate
Economists frequently try to estimate the societal cost of releasing carbon dioxide into the atmosphere, but few of their projections go beyond the year...
At least 28 extinctions prevented by conservation action in recent decades
Conservation action has prevented the global extinction of at least 28 bird and mammal species since 1993, a study led by Newcastle University, UK...
Researchers reveal a much richer picture of the past with new DNA recovery technique
Researchers at McMaster University have developed a new technique to tease ancient DNA from soil, pulling the genomes of hundreds of animals and thousands...
