<!– –> Sometimes it pays to have big, bad neighbors. Weighing in at about 3 grams, black-chinned hummingbirds (Archilochus alexandri) can do little but stand by and watch Mexican jays 40 times their weight chow down on their eggs. So in the mountains of southeastern

<!– –> Trees in cities throughout the UK could be significantly improving the quality of the air we breathe by decreasing pollution levels for pedestrians, researchers from the University of Leicester have revealed. The team from the University of Leicester’s Departm

<!– –> A team from the Centre for Novel Agricultural Products (CNAP) in the University’s Department of Biology has unravelled the mechanism of TNT toxicity in plants raising the possibility of a new approach to explosives remediation technology. TNT has become an ext

A new satellite study has calculated that there are more than 3 trillion trees on Earth, around 422 trees for every person, although the number is believed to have dropped by 46 percent since the start of human civilisation. The Yale-led international research found the result of the

<!– –> On both sides of the Bering Strait, summer sea ice has once more dropped to a level that is driving thousands of walruses onto coastal beaches. Photos taken in Ryrkaypiy in Chukotka, Russia show an estimated 5,000 walruses hauled out in that spot, while across

<!– –> A new international study is the first to use a high-resolution, large-scale computer model to estimate how much ice the West Antarctic Ice Sheet could lose over the next couple of centuries, and how much that could add to sea-level rise. The results paint a c

As a raindrop falls through the atmosphere, it can attract tens to hundreds of tiny aerosol particles to its surface before hitting the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot

Global sea levels have risen nearly 3 inches in less than 25 years, with some locations around the world rising more than 9 inches, according to NASA’s latest satellite data. An intensive research effort now underway, aided by NASA observations and analysis, points to an unavoidable r

Each spring, powerful dust storms in the deserts of Mongolia and northern China send thick clouds of particles into the atmosphere. Eastward winds sweep these particles as far as the Pacific, where dust ultimately settles in the open ocean. This desert dust contains, among other miner

Everyday cosmetic and cleaning products contain huge quantities of plastic particles, which are released to the environment and could be harmful to marine life, according to a new study. Research at Plymouth University has shown almost 100,000 tiny ‘microbeads’ – each a fraction of a
