A study spanning 10 national forests and 14 burned areas in California found that conifer seedlings were found in less than 60 percent of the study areas five to seven years after fire. Of the nearly 1,500 plots surveyed, 43 percent showed no natural conifer regeneration at all.

Rudolph's antlers inspire next generation of unbreakable materials
The team looked at the antler structure at the 'nano-level', which is incredibly small, almost one thousandth of the thickness of a hair strand, and were able to identify the mechanisms at work, using state-of-the-art computer modelling and x-ray techniques.
First author Paolino De Falco from QMUL's School of Engineering and Materials Science said: "The fibrils that make up the antler are staggered rather than in line with each other. This allows them to absorb the energy from the impact of a clash during a fight."
Scientists bear witness to birth of an ice cloud
RICHLAND, Wash. – Scientists have witnessed the birth of atmospheric ice clouds, creating ice cloud crystals in the laboratory and then taking images of the process through a microscope, essentially documenting the very first steps of cloud formation.
Studying the distant past in the Galapagos Islands
The Galápagos Islands are home to a tremendous diversity of plants and animals found nowhere else in the world. But why this is, and when it all began, remains something of an open question. Now scientists may have at least one more piece of the puzzle. According to a new study out today in the journal Earth and Planetary Science Letters, the geologic formation of one particular part of the archipelago--the part responsible for the huge biodiversity--formed, approximately 1.6 million years ago.

Chemicals of 'emerging concern' mapped in 3 Great Lakes
For the first time, researchers at the University of Illinois at Chicago have mapped the location of thousands of tons of polyhalogenated carbazoles in the sediment of the Great Lakes and estimated their amount.
