UK scientists have created a synthetic molecule that, when applied to crops, has been shown to increase the size and starch content of wheat grains in the lab by up to 20%.
The new plant application, developed by Rothamsted Research and Oxford University, could help solve the issue of increasing food insecurity across the globe. Some 795 million people are undernourished, and this year's El Nino has shown how vulnerable many countries are to climate-induced drought.
The total shoreline of the world’s lakes is more than four times longer than the global ocean coastline. And if all the water in those lakes were spread over the Earth’s landmass, it would form a layer some four feet (1.3 metres) deep.
Those are just two of the big-picture findings to emerge from the most complete global database of lakes to date, compiled by geographers at McGill University. Their research, published in Nature Communications, promises to help scientists better understand the important role of lakes in the Earth’s complex environmental systems – from the hydrological cycle and weather patterns, to the transport, distribution or storage of pollutants and nutrients through the landscape.
Maximizing cereal crop yields in sub-Saharan Africa would still fail to meet the region’s skyrocketing grain demand by 2050, according to a new study from the University of Nebraska-Lincoln, Wageningen University and multiple African institutions.
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.
Scientists based at Oxford University have created a new method for counting lions that they say is the most robust yet devised.
Using the Maasai Mara National Reserve and surrounding conservancies in Kenya as a case study, they estimate there to be 420 lions over the age of one in this key territory. At almost 17 lions per 100 square kilometres, that represents one of the highest densities anywhere in Africa.
Few Americans may be aware of it, but in 1952 a killer fog that contained pollutants covered London for five days, causing breathing problems and killing thousands of residents. The exact cause and nature of the fog has remained mostly unknown for decades, but an international team of scientists that includes several Texas A&M University-affiliated researchers believes that the mystery has been solved and that the same air chemistry also happens in China and other locales.
