The first common crane egg in the western United Kingdom in over 400 years has been laid at WWT Slimbridge Wetland Centre in Gloucestershire, England. A round-the-clock guard has been set up to protect the egg from collectors, as despite egg collecting being illegal in the UK it is still practiced by an unscrupulous minority. Video cameras are in place to allow the public to view the nest, as well as to provide important footage for conservation scientists. Lucky visitors can also view the nest from the centre’s bird hides.

It seems that there is always another opinion on how the climate is or will be changing. A new study led by Oxford University concludes that the latest observations of the climate system’s response to rising greenhouse gas levels are consistent with conventional estimates of the long-term climate sensitivity, despite a warming pause over the past decade. However, the most extreme rates of warming simulated by the current generation of climate models over 50- to 100-year timescales are looking less likely, according to the paper published online by Nature Geoscience.

We’ve always been told that eating colorful foods has many health benefits. And no, I’m not talking about artificially colored candies or chips, but instead fresh fruits and vegetables. Many produce rich in color contains nutrient packed pigments and antioxidants that provide energy and other benefits to our bodies. Consequently, it is recommended that we have three to five servings of fruits and vegetables every day. But what about white foods? Some nutritionists urge us to stay away from white bread breads, rice and pastas, but what about white produce? There are potatoes, garlic, onions, mushrooms, cauliflower, onions, turnips and kohlrabi just to name a few. Are these white fruits and vegetables just as nutritious?

Most of the world’s frozen water is locked up at the poles. 99 percent of Earth’s land ice is located in the Greenland and Antarctic ice sheets. Yet the remaining ice in the world’s glaciers contributed just as much to sea rise as the two major ice sheets combined from 2003 to 2009, says a new study led by Clark University and involving the University Colorado Boulder. The new research found that all glacial regions lost significant mass from 2003 to 2009, with the biggest ice losses occurring in Arctic Canada, Alaska, coastal Greenland, the southern Andes and the Himalayas. The glaciers outside of the Greenland and Antarctic sheets lost an average of roughly 260 billion metric tons of ice annually during the study period, causing the oceans to rise 0.03 inches, or about 0.7 millimeters per year.

Lobster fishing remains big business off the coast of Maine but even with new regulations and new gadgets can it ever be sustainable? Michael Sanders investigates the real costs of the crustacean on your plate… When most of us go down to the coast, whether to walk or swim or fish or sail, we take for granted what we see before us. We see the lobster boats and the colorful buoys marking the strings of traps, the bobbing green and red cans marking safe passage, the gulls and other seabirds. In the larger working harbors like Portland and Stonington and Port Clyde, there might be draggers tied up, unloading fish they’ve caught far out in the Gulf of Maine and on Georges Bank. What we don’t realize is that this seemingly unchanging marine world is in fact always changing in ways both large and small. What we think of as “the coast of Maine” – those 3,000 vaunted miles of rocky shoreline punctuated by seaside villages and docks and lobster pounds and fishing fleets – was largely built on the backs of the fishermen and lobstermen who are there, however picturesque or authentic to the eye, for a single purpose: to harvest the sea in order to feed us.

Vitamin C or L-ascorbic acid, or simply ascorbate (the anion of ascorbic acid), is an essential nutrient for humans and certain other animal species. Vitamin C has been advocated for many other therapeutic uses. Vitamin C functions as an antioxidant and is necessary for the treatment and prevention of scurvy, though in nearly all cases dietary intake is adequate to prevent deficiency and supplementation is not necessary. Though vitamin C has been promoted as useful in the treatment of a variety of conditions, most of these uses are poorly supported by the evidence and sometimes contraindicated. Despite previous studies touting its benefit in moderating gout risk, new research reveals that vitamin C does not reduce uric acid (urate) levels to a clinically significant degree in patients with established gout. Vitamin C supplementation, alone or in combination with allopurinol, appears to have a weak effect on lowering uric acid levels in gout patients according to the results published in the American College of Rheumatology (ACR) journal, Arthritis & Rheumatism.

Feral goats and green iguanas wreaking havoc with the ecosystems in the small islands in the Pacific, biologists warn, in two separate studies published in Pacific Science last month, calling for control or elimination of these animals. The animals have been introduced there by humans, but are now threatening the survival of native wildlife.

Methane is created naturally near the Earth’s surface, primarily by microorganisms by the process of methanogenesis. It is carried into the stratosphere by rising air in the tropics. Methane is a potent greenhouse gas, stronger than carbon dioxide on a 20-year timescale, according to the Intergovernmental Panel on Climate Change, though on a century timescale, carbon dioxide is far stronger. “This research suggests significant benefits to slowing climate change could result from reducing industrial methane emissions in parallel with efforts on carbon dioxide,” said Ira Leifer, a researcher with UC Santa Barbara’s Marine Science Institute. Doing a a cross-continent drive, a UC Santa Barbara scientist has found that methane emissions across large parts of the U.S. are higher than is currently known, confirming what other more local studies have found. Their research is published in the journal Atmospheric Environment.

Leonardo DiCaprio’s environmental charity auction at Christie’s in New York has raised an impressive $33.3 million from wealthy art collectors. Most of the sale proceeds went to environmental protection causes promoted by the Leonardo DiCaprio Foundation. The Hollywood actor, who was himself present at the auction, urged collectors to bid as if the planet’s fate “depends on us” – and they responded to his call generously.

Short, sharp fluctuations in the Earth’s climate throughout the last ice age may have stopped trees from getting a foothold in Europe and northern Asia, scientists say. According to a new study, warm spells were so brief that trees were unable to establish themselves before the temperature shot back down again. ‘The warm events were so short-lived that ecosystems weren’t able to respond in full,’ says Professor Brian Huntley, of Durham University, who led the study.
