Why Toddlers Don't Do What They're Told ?

Are you listening to me? Didn't I just tell you to get your coat? Helloooo! It's cold out there...

So goes many a conversation between parent and toddler. It seems everything you tell them either falls on deaf ears or goes in one ear and out the other. But that's not how it works.

Toddlers listen, they just store the information for later use, a new study finds.

"I went into this study expecting a completely different set of findings," said psychology professor Yuko Munakata at the University of Colorado at Boulder. "There is a lot of work in the field of cognitive development that focuses on how kids are basically little versions of adults trying to do the same things adults do, but they're just not as good at it yet. What we show here is they are doing something completely different."

Iridium Satellite Collision

A U.S. Iridium telecommunications satellite and a Russian satellite that was no longer in operation collided over Siberia on Feb 10, announced Wednesday a spokesman for the NASA.

The collision, which is a first in history, involved a satellite belonging to the company Iridium Satellite LLC and a "not operational" Russian telecommunications device .

"The incident occurred Tuesday on a low Earth orbit, about 500 miles over Siberia, "said Lieutenant Colonel Kodlick The U.S. Strategic Command.

"We believe that this is the first time two devices come into collision in orbit," he said.

The Iridium 33 (NORAD ID 24946) was launched in 1997 and was reported to be operational.

The Russian device was the Cosmos 2251 (NORAD ID 22675), a communication relay satellite, launched in 1993, that was no more operational.

Partial Solar Eclipse in India on Monday, January 26, 2009

As the country celebrates Republic Day on Monday, a partial solar eclipse will occur in the afternoon when the moon will pass directly between the earth and the sun.

The partial phase of the eclipse will be visible in southern India, the eastern coastal belt, most of north-east, Andaman and Nicobar Islands and Lakshadweep, Director of Nehru Planetarium N Rathnashree said.

The eclipse will be annular in regions covering south of Africa, Antarctica, South East Asia and Australia.

Annular solar eclipse occurs when the moon is farther from the earth than normal in its elliptical orbit and hence, its apparent size is not sufficient to cover the sun completely, Director of Science Popularisation Association of Communicators and Educators (SPACE) C B Devgun told PTI.

Alaska Earthquake

According to several sources like The Anchorage Daily News or the The Post Chronicle, an earthquake with a magnitude of 5.73 hit South-central Alaska at at 9:09 a.m this morning.

The information was confirmed by the Alaska Earthquake Information Center at the University of Alaska (Fairbanks).

The quake’s epicenter was 162 miles SW of Anchorage.
The quake occurred at Latitude 59.3888, Longitude -152.8107, at a depth of 62 miles. No injury nor damage were reported.

The AEIC, which monitor all seismic activities across Alaska, is reporting more than 20,000 earthquakes each year, and 20 just for today but ranking from micro ( Read more »

President Has Four Years To Save Earth

According to Dr James Hansen, President Barack Obama has only four years to save the world. That is the stark assessment of Nasa scientist and leading climate expert Jim Hansen who last week warned only urgent action by the new president could halt the devastating climate change that now threatens Earth. Crucially, that action will have to be taken within Obama's first administration, he added.

Soaring carbon emissions are already causing ice-cap melting and threaten to trigger global flooding, widespread species loss and major disruptions of weather patterns in the near future. "We cannot afford to put off change any longer," said Hansen. "We have to get on a new path within this new administration. We have only four years left for Obama to set an example to the rest of the world. America must take the lead."

Could Coccolithophores Save The Earth From Global Warming ?

Ever heard of Coccolithophores? Despite their small size and their weird name, these tiny single-celled marine organisms are major regulators of global climate.

Most of the models used to predict climate change are based on ocean level, carbon dioxide and temperature measurements but fail to integrate marine ecosystems in their projections.

Actually, the whole process of climate and gas regulation by marine organisms is so complex that it is quite impossible to integrate in already complex models...and much more impossible to explain in details in this artile. I'll try to do my best to keep it simple, concentrating on one of the top players, the Coccolithophores.

Colony Collapse Disorder: Bees Need An Emergency Plan

Although the disappearence of billions of bees without any trace of dead bees around hives may sound like a urban legend, the Colony Collapse Disorder is a real and frightening phenomenon that could lead to an overall wipeout of the world's food supply.

While a dramatic decrease of feral and domestic bees has been observed in the US since 1971, it is only in 2006 that some US beekeepers started to report massive disappearence of up to 90% of their bees colonies. And since then, similar reports are coming from other countries like Germany, France, UK, Italy, Spain, India or Brazil.

The honey bee is a major actor in the food chain, as roughly 90% of vegetal species depend on bees as pollinators, and 30% of the US crops would not exist without pollination. This include all the fruit trees, but also many other crops like cucumbers, squash, melons and all kinds of berries.

The Saline Solution

In the mid-'80s, an atmospheric physicist named Carl N. Hodges predicted that the key to saving the planet was to make the desert bloom—with a spindly saltwater plant known as salicornia, a.k.a. sea asparagus.

The idea languished for years, but now scientists, investors, and even celebrities are lining up behind the 71-year-old's vision for feeding the planet, fueling our cars, and reversing rising sea levels. "I don't know if I'm slow or the world is," says Hodges, the founder of the University of Arizona's Environmental Research Laboratory, "but finally it has all come together."

Global Warming In The Agenda Of The Pittsburgh G20 Summit

Sept. 24, 2009 - Last summit in London was centered around the financial crisis and the best strategies to get the global economy out of recession. Although it is expected that the reform of international financial institutions will still be an important part of the discussion in today Pittsburgh summit, some sentences in president Barack Obama address to the UN indicate that global warming will be part of the agenda.

According to sources in the White House, the US president will propose to his G20 partners a plan to eliminate subsidies on fossil fuels, in order to encourage the use of renewable energy and to fight against global warming.

Kiss Global Warming Goodbye, Say Hello To Global Cooling

While the UN, the ICCP and the WWF are calling world leaders to make all the necessary efforts to reach an agreement on greenhouse gases reduction at the United Nations Framework Convention on Climate Change which will be held in Copenhagen in December (read Global Warming In The Arctic Above All Predictions), some scientists still dare to express opinions that conflict with the prevailing scientific opinion.
