A highly destructive, invasive, mussel threatens Britain for first time
This is extremely worrying wildlife experts are warning. Quagga mussels have been described as 'ecosystem engineers' because their vast capacity to filter water upsets the natural balance throughout the food web. They eat some pollutants, but they turn it into concentrated toxic faeces which can poison drinking water for people and wildlife. - Halil from Bookmarklet
The Wildfowl & Wetland Trust’s head of conservation policy, Jeff Knott said: “This is a worrying, but entirely predictable, development that could be devastating to British wetlands. Quagga mussels are likely to indirectly cause suffering and death for hundreds of thousands of native animals, fish and plants and cost millions of pounds in tax and water bills to protect drinking water supplies. - Halil

Wind turbines kill fewer birds than do cats, cell towers - http://www.usatoday.com/story...
Wind turbines kill fewer birds than do cats, cell towers
And those two combined are nothing compared to how many birds die by flying into windows. - Jenny H. from Android
Two problems with that statistic: one is that wind turbines are still a relatively small portion of energy generation. As its share of energy production grows, the number of birds killed by turbines is likely to grow unless the energy industry can reduce bird kills per turbine. The second is that there is a difference between killing common songbirds (as cats do) and killing Golden Eagles (as some wind farms do). - John (bird whisperer)

Antarctica Has Lost Enough Ice to Cause a Measurable Shift in Gravity
“The loss of ice from West Antarctica between 2009 and 2012 caused a dip in the gravity field over the region,” writes the ESA, whose GOCE satellite measured the change. Apparently, melting billions of tons of ice year after year has implications that would make even Isaac Newton blanch. - Halil from Bookmarklet

Adjusting wind power production during migration season saves bats
"With minimal loss in power production—and hence revenue—and with the aid of the bat shield, First State Marine Wind was able to realize a significant reduction in bat fatalities," Firestone said. A great advantage of the bat shield is that "we can program in changes to the cut-in speed that are tied to atmospheric conditions and time of year and time of day so that turbines can be easily adjusted to protect bats," he said - Halil

Reserves and parks not enough to protect nature – David Attenborough
But rather than lament the changes, he urged everyone to act. “We know climate change is happening. It is regretted by some but it is also to be embraced. It is causing great changes in the distribution of animnals and birds in the countryside. We must take advantage of that. It is very important that we accept there are things coming in ... We must recognise that new animals and plants are coming in. Others are moving north. We ought to be giving thought to wildlife corridors ... and not think that every new arrival is to be repelled. - Halil from Bookmarklet

Most of the fish and birds that she's studied have come from Lake Erie. Mason and her students began collecting fish in January by going to local ice fisherman; Mason wound up with a lot of perch, since that's what they were catching. Through the spring, Mason and her student assistants examined 75 perch and 17 cormorants, a type of water bird. In both cases, a high percentage of the subjects had plastics in their gastrointestinal tracts, Mason says. - Halil from Bookmarklet

UK Professor Tom Curtis : I make no apologies for putting micro-organisms on a pedestal above all other living things, for if the last blue whale choked to death on the last panda, it would be disastrous but not the end of the world.

A new assessment from Europe's CryoSat spacecraft shows Greenland to be losing about 375 cu km of ice each year. Added to the discharges coming from Antarctica, it means Earth's two big ice sheets are now dumping roughly 500 cu km of ice in the oceans annually. "The contribution of both ice sheets together to sea level rise has doubled since 2009," said Angelika Humbert from Germany's Alfred Wegener Institute. "To us, that's an incredible number," she told BBC News. - Halil from Bookmarklet

Stacked solar cells could make solar power cheaper than natural gas : TreeHugger
" Researchers everywhere are working on developing better solar cells: ones with higher power output, ones that can adhere to any surface, ones that cool or clean themselves, etc. Upping the efficiency of solar cells is probably the biggest focus. Right now, commercial solar cells can convert about 15 to 25 percent of the energy from sunlight into electricity. The holy grail for years has been reaching a 50 percent conversion efficiency. In labs, researchers have been able to hit efficiencies as high as 44.7 percent, but the start-up Semprius says they have a technique for stacking solar cells that would lead to that magic 50 percent number, and not just in a lab. Not only that, but because the solar cells are small and cheap to manufacture, the company believes that this technology could also lead to solar power cheaper than natural gas. MIT Technology Review says, "Semprius has come up with three key innovations: a cheap, fast way to stack cells, a proprietary way to electrically... more... - Bluesun 2600 from Bookmarklet

Changing farming practices could cut the intensity of heat waves | Ars Technica
"As the Earth's climate continues to warm, the elevated temperatures can put a strain on agriculture. Although an increase in the average temperature can harm crops, it's the details obscured by that average that can cause the biggest problems: more—and more extended—periods of extreme temperatures often harm crops far more than raising the typical temperature a fraction of a degree." - imabonehead from Bookmarklet
"Fortunately, as a team of Swiss and French researchers have determined, the opposite may also be true. They've identified a simple agricultural practice that does little to alter the average temperature of farming areas. But it does have a strong effect on extreme temperatures, lowering them by nearly 2°C. That should be enough to keep existing crops viable for longer in the face of future climate change." - imabonehead
"The technique in question is called "no-till farming," and it simply involves leaving the debris from previous crops on the surface of the fields rather than plowing the fields and exposing the soil underneath. Observations of test agricultural fields indicate that no-till practices have several effects. To begin with, the debris tends to retain moisture, which limits evaporation;... more... - imabonehead

This tiny portable wind turbine fits in your bag and charges your gadgets : TreeHugger
"In our current gadget-centric culture, one limiting factor for mobile devices is the capacity of the batteries that power them, and while we haven't seen any massive improvements in battery technology (yet) which would allow us to go for days between charges, mobile solar chargers and battery backup systems seem to be the only solutions (well, other than to actually stop using them so much). Wind turbines are a viable clean energy solution, but most of the innovations in wind energy tend to be on the large scale, and since those devices aren't exactly portable, they don't lend themselves to mobile device charging. But one forthcoming invention may allow us to harness the power of the wind with a micro turbine, in order to charge our smartphones and tablets and other USB devices. Although the efficacy of small wind turbines, especially vertical axis wind turbines (VAWT), is often debated, and the designs dismissed as not being worth their cost or manufacturing resources, but that... more... - Bluesun 2600 from Bookmarklet

Will We Still Have Fruit if Bees Die Off? | Science Blogs | WIRED
"A photo has been circulating for a while that suggests our grocery stores will look like this in a world without bees. Is that true? Will our food choices be radically limited, come the future Beepocalypse? We already know what raising fruit without honey bees looks like. In a remote area in China, humans pollinate 100% of fruit trees by hand. Armed with pollen-loaded paintbrushes and cigarette filters, people swarm around pear and apple trees in spring. The reason why they hand pollinate is not what you think, though. Honey bees are still present in these areas of hand pollination, and many fruit growers also keep bees for honey. Hand pollination in China has as much to do with economics and fruit biology as it does with bees. In the early 1990s, farmers of marginal lands in the Hindu Kush Himalayan region–an area spanning parts of Nepal, China, Pakistan, and India–realized that apples could be a major cash crop. Their land was mountainous and hard to farm, so tree fruits were... more... - Bluesun 2600 from Bookmarklet
