High-Severity Wildfires Complicate Natural Regeneration for California Conifers

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."

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.

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.

Scientists: Strong evidence that human-caused climate change intensified 2015 heat waves

Human-caused climate change very likely increased the severity of heat waves that plagued India, Pakistan, Europe, East Africa, East Asia, and Australia in 2015 and helped make it the warmest year on record, according to new research published today in a special edition of the Bulletin of the American Meteorological Society.  

The fifth edition of Explaining Extreme Events from a Climate Perspective presents 25 peer-reviewed research papers that examine episodes of extreme weather of 2015 over five continents and two oceans. It features the research of 116 scientists from 18 countries analyzing both historical observations and changing trends along with model results to determine whether and how climate change may have influenced the event.

Americans believe climate change connected to location and local weather

A new study finds local weather may play an important role in Americans’ belief in climate change. The study, published on Monday, found that Americans’ belief that the earth is warming is related to the frequency of weather-related events they experience, suggesting that local changes in their climate influence their acceptance of this worldwide phenomenon. 

“One of the greatest challenges to communicating scientific findings about climate change is the cognitive disconnect between local and global events,” said Michael Mann, associate professor of geography at George Washington University and co-author of the paper. “It is easy to assume that what you experience at home must be happening elsewhere.”

El Niño fuelled Zika outbreak, new study suggests

Scientists at the University of Liverpool have shown that a change in weather patterns, brought on by the 'Godzilla' El Niño of 2015, fuelled the Zika outbreak in South America. The findings were revealed using a new epidemiological model that looked at how climate affects the spread of Zika virus by both of its major vectors, the yellow fever mosquito (Aedes aegypti) and the Asian tiger mosquito (Aedes albopictus).

The model can also be used to predict the risk of future outbreaks, and help public health officials tailor mosquito control measures and travel advice.

Millions exposed to mercury in urban Pakistan

More than 40 per cent of Pakistanis living in urban areas are exposed to mercury contamination through dust particles and bioaccumulation, says a new study.  

The study, published last month (November) in Science of the Total Environment, amassed hair samples from 22 sites in five zones in Pakistan — Swat Valley & Gilgit-Baltistan regions, Kashmir Valley, Lower Himalaya Mountains and Indus Plains.

7 Sustainable Holiday Gift Ideas

Tis the season, and we all are buying gifts. The question is how to do so without saddling friends and families with returns, throwaway gift paper or mounds of fattening desserts.

Here are seven gift ideas that show you care for not only the person receiving the gift, but also for people and planet.

1. Make a donation

This is my favorite gift. I give to a charity that I think aligns with the gift recipient’s passions. Does she love dogs? A gift in her name to the humane society always results in a truly genuine positive response. What family is not touched by health issues like heart disease or cancer? A gift to the Heart Association or Cancer Society is a thoughtful and meaningful way of saying you care. Looking for a charity? I use Charity Navigator to find credible nonprofits. The site also has top 10 lists that cover a diverse range of charities.
