Could It Be The Missing Link In Anthropoid Evolution?

The New York Natural History Museum presents the remains of a primate that could be the "missing link".

Ida is 47 million years old but is very well preserved for its age. "It is the most complete primate fossil that was ever found," explains the group of scientists that is presenting today the remains of a young female who, they say, could be the "missing link" in the evolution of anthropoids.

The fossil of Ida, 58 centimeters in length, is twenty times older than the majority of existing remnants that explain the human evolution. Scientists say that it could be a transitional specy that shows characteristics of a very primitive prosimian lineage, at the root of the anthropoid evolution, when the first primates developed features that later evolve into monkeys, apes and humans species.

Mathematics: New Pattern Found in Prime Numbers

PhysOrg.com -- In a recent study, Bartolo Luque and Lucas Lacasa of the Universidad Politécnica de Madrid in Spain have discovered a new pattern in primes that has surprisingly gone unnoticed until now. They found that the distribution of the leading digit in the prime number sequence can be described by a generalization of Benford’s law. In addition, this same pattern also appears in another number sequence, that of the leading digits of nontrivial Riemann zeta zeros, which is known to be related to the distribution of primes. Besides providing insight into the nature of primes, the finding could also have applications in areas such as fraud detection and stock market analysis.

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.

Genetically Modified Trees Can Give Direction To Lost Hickers

A small step for genetic engineering, but a big step for mankind, at least for people unable to read a map or to use a GPS to find their way when hicking in national parks: BioTeckTrees Corp. (NasdaqGS: BTTC) has just announced that they have successfully introduced electric eel (Electrophorus electricus) genetic material into a Whitebark Pine (Pinus albicaulis; family Pinaceae) and that they will soon be able to design the trees so they can give direction to lost hickers.

Electrophorus electricus, also know as "electric eel" or "tremblador" is an electrical fish, capable of generating powerful electric shocks. This electric power generation property will also allow the tree to recharge lost hickers' mobile phones.

Despite strong resistance from environmentalists who are opposed to the introduction of GM plants in American forests, the first tree should be planted on April 1st in Redwood National Park (Ca).

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.

Scientists See Asteroid Hurtle To Earth !

Stunned astronomers watched a car-sized asteroid explode into a brilliant meteor shower as it crashed into Earth's atmosphere.

It was the first time ever that scientists recovered fragments from an asteroid detected in space, according to the study, published in the British journal Nature on Wednesday.

'Any number of meteorites have been observed as fireballs and smoking meteor trails as they come through the atmosphere,' said co-author Douglas Rumble, a researcher at the Carnegie Institution for Science.

'But to actually see this object before it gets to the Earth's atmosphere and then follow it in - that's the unique thing.'

The drama unfolded like an overheated Hollywood script, according to a reconstruction of the event by Nature.

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."

Mount Redoubt Erupts 4 Times In 3 Hours

Mount Redoubt erupts 4 times in 3 hours; ash fall reported in Skwentna; flights canceled.

Check back with KTUU.com for more information as it becomes available.

ANCHORAGE, Alaska -- Mount Redoubt erupted four times three hours late Sunday and early Monday, and the Alaska Volcano Observatory says the most recent was the largest so far.

"Beginning at 10:38 p.m. (Sunday) night, we began to have explosive activity," geophysicist John Power with the United States Geological Survey said. "At this point we have recorded four separate explosive events.

"These events were very large, explosive eruptions of Redoubt Volcano."

An eruption cloud is estimated to be at 50,000 feet above sea level at present.

Alaska's Mount Redoubt Erupts Four Times

Alaska's Mt. Redoubt volcano erupted late Monday and early Tuesday in "four large explosions," sending an ash plume an estimated 9 miles into the air, the Alaska Volcano Observatory reported.

"The ash cloud went to 50,000 feet, and it's currently drifting toward the north, northeast," said Janet Schaefer, a geologist with the Alaska Volcano Observatory.

Geologists at the observatory say the volcano, located 100 miles southwest of Anchorage, erupted four times, from 10:30 p.m. to 1:40 a.m. local time.

"This is a fairly large eruption, close to the larger cities in Alaska," Geophysicist John Power said. He said nearby cities have not yet reported ash fall from the volcano, but noted that it's still early.

Using radar and satellite technology, the National Weather Service is predicting ash to start falling later Monday morning.

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."
