GMOs: The Walking Dead of the Food Industry
An expedition into one of the most remote areas on Earth has shed new light on the fate of the New Guinea singing dog – one of the world's rarest canines.
New Sinking Islands and Lands
The seas do rise and fall over the ages. Lands sink and rise depending on the weather. Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research, according to a new report. A team led by research oceanographer Curt Storlazzi of the USGS Pacific Coastal and Marine Science Center compared passive bathtub inundation models with dynamic models for two of the Northwestern Hawaiian Islands in the Papah?naumoku?kea Marine National Monument. The team studied Midway, a classic atoll with islands on the shallow (2–8 meters or 6–26 feet deep) atoll rim and a deep, central lagoon, and Laysan, which is higher, with a 20–30 meter (65–98 feet) deep rim and an island in the center of the atoll. Together, the two locations exhibit landforms and coastal features common to many Pacific islands.
How Fast is Global Climate Changing?
There's plenty of evidence that the climate has warmed up over the past century, and climate scientists know this has happened throughout the history of the planet. But they want to know more about how this warming is different. Now a research team says it has some new answers. It has put together a record of global temperatures going back to the end of the last ice age — about 11,000 years ago — when mammoths and saber-tooth cats roamed the planet. The study confirms that what we're seeing now is unprecedented.
Is Ice Loss by Glaciers Abnormal?
In the last few decades, glaciers at the edge of the icy continent of Antarctica have been thinning, and research has shown the rate of thinning has accelerated and contributed significantly to sea level rise. New ice core research suggests that, while the changes are dramatic, they cannot be attributed with confidence to human-caused global warming, said Eric Steig, a University of Washington professor of Earth and space sciences. Previous work by Steig has shown that rapid thinning of Antarctic glaciers was accompanied by rapid warming and changes in atmospheric circulation near the coast. His research with Qinghua Ding, a UW research associate, showed that the majority of Antarctic warming came during the 1990s in response to El Niño conditions in the tropical Pacific Ocean.
New Camera Takes Better Pictures of Snowflakes
Winter may be over for most of us in the Northern Hemisphere, and hopefully we will not be expecting any more snowfall, but that doesn't mean we still can't marvel at the intricacies of the snowflake. A team of researchers at the University of Utah have developed a new high-speed camera system that records 3-D images of these snowflakes in hopes of improving radar for weather and snowpack forecasting. Funded in part by NASA and the US Army, the team studied falling snow and how it interacts with radar in order to improve computer simulations. As a result, the research has revealed more about how snowy weather can degrade microwave (radar) communications.
The Cicadas are Coming!
Remember seventeen years ago when those creepy looking orange and black insects covered nearly every tree and you could barely step outside without crunching on a molted shell or cringing when these winged creatures flew by? Maybe they weren’t in your neighborhood, but all along the eastern seaboard of the United States from New York to North Carolina, millions of these half-inch long cicadas swarmed around for nearly a month. And guess what? This spring, these little critters will emerge from the ground once again. In fact, the cicadas are probably starting to plan their escape right now, as several weeks before emerging, they start to build small cones that stick above the soil.
Fungi Found to be Culprit for Horseradish Root Rot
Horseradish grown in the Midwest of the United States has been experiencing significant yield reductions for the past 30 years due to internal discoloring and root rot. According to crop science professor Mohammad Babadoost at the University of Illinois, "If the roots are discolored, they are not accepted for processing." This affects the success of these plants and the livelihood of Illinois farmers who grown over half of the horseradish produced in the United States.
Britain's love affair with bottled water
Leading academic brands industry a "scam" as campaigners condemn our growing thirst for bottled water. The UK bottled water industry releases 350,000 tonnes of carbon dioxide into the atmosphere each year. One of Britain's leading authorities on water supplies has branded the bottled water industry a scam, backing campaigners' claims of wasted millions and environmental pollution at a time when tap water standards have never been higher. Professor Paul Younger, Rankine Chair of Engineering at Glasgow University, has highlighted growing fears that our increasing consumption of bottled water is damaging the environment while raising huge profits for the big brands, despite Britain having one of the best mains water supplies in the world.
