Widely used pesticides have been found in new research to block a part of the brain that bees use for learning, rendering some of them unable to perform the essential task of associating scents with food. Bees exposed to two kinds of pesticide were slower to learn or completely forgot links between floral scents and nectar.
These effects could make it harder for bees to forage among flowers for food, thereby threatening their survival and reducing the pollination of crops and wild plants. The findings add to existing research that neonicotinoid pesticides are contributing to the decline in bee populations.
Pesticide makes bees forget the scent for food, new study finds
5.7 Oklahoma earthquake linked to oil extraction wastewater
Scientists have linked the underground injection of oil-drilling wastewater to a magnitude-5.7 earthquake in 2011 that struck the US state of Oklahoma. Wastewater injection from drilling operations has been linked to seismic events in the past, but these have typically been much smaller quakes.
They also have tended to occur in the first weeks or months of injection. The study in Geology suggests that "induced seismicity" can occur years after wastewater injection begins.
EPA: Most U.S. waters polluted
More than half of U.S. rivers, streams and other waterways are in too poor of a condition for aquatic life, the Environmental Protection Agency said. The EPA said most the nation's streams, rivers and other waters were in poor health.
EPA analysis said that 27 percent of the nation's waterways have high levels of nitrogen and 40 percent have high levels of phosphorus. Those chemicals lead to algae blooms that can deprive water of oxygen.
Bob Alexander: Here Comes Jeebus Cottontail
Just to set the record straight … I am not a tolerant person. If you believe, follow, and make decisions based upon any of the big deal world religions … I think there’s something wrong with you. I think you’re suffering a low-grade psychotic break with reality. So right off the bat I find it pretty hard to get along with 59% of the world's population. But then again 80% of the countries in the world are capitalist nations. I have a problem with them too as they are equally delusional and arguably more dangerous. And if you’re a religious capitalist … you’re the beast of both worlds.
A friend of mine told me years ago that religion is for people who lack spirituality. I’d add that religion is for people who lack imagination. They need other people to make up stuff for them. “Stuff” of course being the euphemism for what bulls regularly manufacture steaming piles of.
Oil and electricity: A compare-and-contrast tale of 2 regulators
An obscure federal regulator of electricity markets has emerged as a tough cop on the beat, taking on Wall Street banks and big energy firms alike for market manipulation. That aggressive approach stands out when it’s compared with that of the regulator in charge of looking for manipulation in the oil and gasoline markets.
Whether manipulation accounts for volatile oil and gasoline prices in recent years is a hotly debated topic since prices began their steep climb in late 2005. Last year’s West Coast price spikes amid ample supplies added to the urgency in determining whether excessive financial speculation is driving price volatility.
Chris Hedges: The Day That TV News Died
I am not sure exactly when the death of television news took place. The descent was gradual—a slide into the tawdry, the trivial and the inane, into the charade on cable news channels such as Fox and MSNBC in which hosts hold up corporate political puppets to laud or ridicule, and treat celebrity foibles as legitimate news.
But if I had to pick a date when commercial television decided amassing corporate money and providing entertainment were its central mission, when it consciously chose to become a carnival act, it would probably be Feb. 25, 2003, when MSNBC took Phil Donahue off the air because of his opposition to the calls for war in Iraq.
Scientists link frozen spring to dramatic Arctic sea ice loss
Melting sea ice, exposing huge parts of the ocean to the atmosphere, explains extreme weather both hot and cold.
Climate scientists have linked the massive snowstorms and bitter spring weather now being experienced across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice.
Marine who helped stage toppling of Saddam Hussein has doubts a decade later
There was no doubt in the young Marine’s mind when he clambered to the top of the enormous statue of Saddam Hussein, tied a noose around its neck — and tore down the graven image.
Brooklyn-born Edward Chin continued to believe in the mission, even as the U.S. death toll mounted in Iraq, even as Saddam’s weapons of mass destruction turned out to be a mirage. Now, 10 years after Chin signaled to the world that Baghdad had fallen, he is not so certain.
UK's BAE Systems wins $780m US military contract
BAE Systems has been awarded a new contract from the US military worth up to $780m (£512m), in a rare spending boost from its largest single customer.
The US is BAE's biggest market but the defence contractor has warned it faced weak demand from across the Atlantic due to the scaling back of operations in Iraq and Afghanistan, as well as public spending cuts.
