Estrogen in Waterways Worse than Thought

© FLICKR/VELO STEVEFISHY WATERS: Some male bass have been growing eggs, which researchers attribute to the presence of estrogen in the rivers.
Exposure to estrogen puts fish at greater risk of disease and premature death, according to a new federal study.

The U.S. Geological Survey study showed that estrogen exposure reduces a fish's ability to produce proteins that help it ward off disease and pointed to a possible link between the occurrence of intersex fish and recent fish kills in the Potomac and Shenandoah rivers.

The report, published in the current issue of Fish & Shellfish Immunology, adds to a growing body of research pointing to problems with estrogen in the nation's waterways.


Earth more habitable because of meteorites

British scientists say large bombardments of meteorites four billion years ago might have made early Earth and Mars more habitable for life.

Imperial College London researchers said millions of meteor strikes during what's called the Late Heavy Bombardment approximately 3.9 billion years pelted Earth and Mars during a period of about 20 million years, possibly modifying the atmosphere on both planets.


Revealed: The Bid to Corner World's Bluefin Tuna Market

Japan's sprawling Mitsubishi conglomerate has cornered a 40 per cent share of the world market in bluefin tuna, one of the world's most endangered fish.

A corporation within the £170bn Mitsubishi empire is importing thousands of tonnes of the fish from Europe into Tokyo's premium fish markets, despite stocks plummeting towards extinction in the Mediterranean.

How Antarctica grew its ice - and lost its hanging gardens

© Martin Siegert et al.Put together, the images reveal a striking landscape of sharp peaks and hanging valleys surrounding a deep gorge carved out by ice
Up to 3000 metres beneath the ice, at the coldest point on Earth, towering peaks, hanging valleys and deep gorges have been frozen in ice for 14 million years. Now the first detailed view of this frozen landscape is revealing how the world's biggest chunk of ice - the Antarctic ice sheet - was born.

The radar images suggest that Antarctica "grew" its ice cap in three stages, carving out the rock below in distinct ways as glaciers expanded, retracted, and flowed downstream.

The images were collected between 2004 and 2008 by researchers who drove huge trains of caterpillar tractors in tight lines over Dome A, a plateau of ice at the heart of Antarctica. The tractors carried radars that pinged down through the ice and sent back profiles of the frozen rock landscape below.

Dome A, the highest point on the continent, is also one of the coldest places on Earth, with temperatures as low as -90 °C. Far beneath its frozen surface lie the Gamburtsev mountains, where glaciologists believe the Antarctic ice sheet was born. Its distance to the ocean and high altitude would have made it the coolest spot on the continent 34 million years ago, when the ice began to grow.

US: Oil, gas drillers in Pennsylvania fight environmental study

Oil and gas drillers in Pennsylvania predict environmental studies required by the federal government to tap into reserves under the Allegheny National Forest would effectively halt the more-than-a-century-old drilling operations there.

A recent settlement of a lawsuit by environmentalists against the Forest Service requires environmental analysis of drilling projects under the federal National Environmental Protection Act.

But the Pennsylvania Oil and Gas Association, Minard Run Oil Co., and Warren County sued the U.S. Forest Service and several environmental groups Tuesday seeking to lift the requirement.


Climate Change: Science Manipulated

Natural causes of global warming are much more significant than manmade changes

1. The Intergovernmental Panel on Climate Change (IPCC) wants to claim that the global average temperature has unexpectedly and abruptly increased during the 20th century after a gradual cooling from the year 1000, and that this unexpected increase of the temperature is mostly man-made-the greenhouse effect of CO2.

2. For their purpose, the IPCC ignored the fact that the Earth went through a cold period called "the Little Ice Age" from 1400 to 1800.

3. The Earth has been recovering from the Little Ice Age from 1800 to the present. A recovery from a cold period is warming. It is mostly this warming that is causing the present climate change and it is not man-made. If they admit the existence of the Little Ice Age, they cannot claim that the global average temperature unexpectedly increased from 1900.

3a. In addition to the steady recovery from the Little Ice Age, there are superposed oscillatory changes. The prominent one is called the multi-decadal oscillation.

3b. In fact, most of the temperature change from 1800 to 2008 can be explained by the combination of the recovery from the Little Ice Age and the multi-decadal oscillation. If the recovery from the Little Ice Age continues, the predicted temperature rise will be less than 1°C (2°F) by 2100, not 3~6°C.

Cloud Lightning

Freak storms pummel Southern California

Two women in the Inland Empire are killed and another injured in lightning-related incidents. Lightning also ignites more than a dozen brush fires.

Thunder rumbled through the Southland and freak storms pelted the region with hail, lightning and unseasonal rain, killing two women in the Inland Empire, bedeviling aviation and touching off more than a dozen brush fires on the parched mountain slopes ringing Los Angeles County.


Sunspot Minimum at Hand

sun spot

The sun has become more active in recent days with cycles 24 spots in middle latitudes. See sunspot group number 11019 for group of red spots. This is slightly diminished since yesterday. The dark green areas are coronal holes out of which the solar wind escapes at higher velocity.

Peter Lawrence has a close up view of that sunspot posted on
sun spopt

There is a loop of the sunspots develop and rotate around the solar disk the last few days here.

This activity came late enough in the month of May, to keep the monthly number for May below the value of 14 months ago of 3.2 which it is replacing in the 13 month running mean. That means the solar cycle minimum can't be earlier than November 2008, making it at least a 12.5 year long cycle 23.

US: 10,000 bees crowd wing of plane at Massachusetts airport

© AFP/File/Saul LoebHoney bees walk on a moveable comb hive at the Bee Research Laboratory, in Beltsville, Maryland in 2007. The number of domesticated bees is on the rise worldwide despite declining numbers of wild honey bees in the United States and Europe, a study said Thursday.
Danvers - Maybe these bees were too tired to fly for themselves. A gang of honeybees landed on the wing of a plane used for flight school training at Beverly Airport. At first, the 10,000 or so bees swarmed over the left side of the aircraft, then landed on top of the left wing. The owner of the flight center called police, who said to call local bee removal expert Al Wilkins.

Wilkins used a specially designed vacuum to suck the bees off the plane, and then relocated them to hives where they will produce honey.
