With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.

A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts.

Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world's oceans over the past 60 years, a University of Adelaide study has found.

The international team, led by researchers from the University's Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term trends in abundance, published in Cell Press journal Current Biology.

For years, one of the major arguments that has been made against genetically engineered crops is the fear that, by tampering with a plant’s DNA, it could potentially cause health issues for consumers. It’s an understandable worry, however, the scientific consensus now seems to be undeniable: Whatever faults GMO crops may have, they are safe for human consumption.

Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting effect on global warming.

Most living organisms adapt their behavior to the rhythm of day and night. Plants are no exception: flowers open in the morning, some tree leaves close during the night. Researchers have been studying the day and night cycle in plants for a long time: Linnaeus observed that flowers in a dark cellar continued to open and close, and Darwin recorded the overnight movement of plant leaves and stalks and called it "sleep". But even to this day, such studies have only been done with small plants grown in pots, and nobody knew whether trees sleep as well. Now, a team of researchers from Austria, Finland and Hungary measured the sleep movement of fully grown trees using a time series of laser scanning point clouds consisting of millions of points each.

SAR11, the most abundant plankton in the world's oceans, are pumping out massive amounts of two sulfur gases that play important roles in the Earth's atmosphere, researchers announced today in the journal Nature Microbiology.

What’s not to love about trees? May 16 marks National Love a Tree Day, which gives everyone a chance to get out and appreciate the

You probably know about the largest living tree: situated in the Giant Forest in California’s Sequoia National Park, the General Sherman tree, a giant sequoia, is the largest living organism, by volume, on our planet. It is 2,100 years old, weighs an estimated 2.7 million pounds, stands 275 feet tall and is 100 feet wide at its trunk. Pretty impressive!

But you don’t have to travel to California to appreciate trees – in fact, they are everywhere!

Though a border wall with Mexico is currently a matter of serious discussion in the United States, the aim of which is to prevent the physical movement of people (with few other apparent “benefits”), some walls can actually bring together and preserve communities, rather than divide them.

In only five years, the UN says, around 60 million Africans may be displaced as their land ceases to be arable, a potential humanitarian disaster the scale of which would be unprecedented. This would be devastating to a huge portion of the African continent not only ecologically and economically but socially as well.

That’s where Africa’s ingenious Great Green Wall comes in.

Experts at the United Nations say without action, desertification may claim two-thirds of Africa’s farmlands in under a decade. The Great Green Wall, however, was conceived as a wide-reaching strategy to halt Northern Africa’s rapidly advancing Sahara Desert.

The Great Green Wall, once complete, will stretch an incredible 4,400 miles from Senegal in West Africa to the East African nation of Djibouti. Instead of bricks and mortar, the wall will be made of trees and other vegetation, including plants that can be eaten or used to create medicine.

The idea that the young Earth had a thicker atmosphere turns out to be wrong. New research from the University of Washington uses bubbles trapped in 2.7 billion-year-old rocks to show that air at that time exerted at most half the pressure of today’s atmosphere.
