Washington, Feb 13 : A new study has indicated that arctic rivers, which transport huge quantities of dissolved organic carbon (DOC) to the Arctic Ocean, has much more impact on its chemistry and biology than previously believed.
The study, conducted by R. M. Holmes of the Woods Hole Research Center and colleagues at collaborating institutions, has challenged the prevailing paradigm regarding DOC in arctic rivers that it is of little significance for the biogeochemistry of the Arctic Ocean.
In fact, the new study has shown that DOC in Alaskan arctic rivers is remarkably adaptable during the spring flood period when the majority of annual DOC flux occurs.

Washington, Feb 13: Despite the huge impact that superstition has on the market place, it also significantly influences decision-making in consumers.
While assessing the role of lucky and unlucky convictions Thomas Kramer and Lauren Block from Baruch College have found that the consumers are more disappointed when a product that they consider “lucky” breaks.
“Despite the large impact that superstitious beliefs have on the marketplace, we currently know very little about their implications for consumer judgment and decision making,” said researchers
“This research is one of the first to investigate the impact of irrational beliefs on consumer behaviour in the marketplace,” they added.

Washington, Feb 13: Psychologists have ultimately found the reason behind people’s reluctance in choosing a mate- sense of scarcity.
The International team led by Xianchi Dai, Klaus Wertenbroch and Miguel Brendl from INSEAD, the international business school have been studying what they call the “value heuristic.”
A heuristic is a sort of cognitive short cut or “rule of thumb” that we use when we are unable to make a truly informed decision.
The study suggests that many mate-seekers are often mystified by thought of how many relationship-worthy bachelors and bachelorettes are still available.
The connection between scarcity and value is something we all know; for example, gold is considered precious because it is rare, not because it makes for a poor construction material.

Washington, Feb 13: A new research has determined that humans had inhabited Beringia, which now lies submerged under the icy waters of the Bering Strait, for almost 20,000 years, before stepping into the New World.
Scientists from the University of Florida (UF) Genetics Institute carried out the research.
“Our model makes for a more interesting, complex scenario than the idea that humans diverged from Asians and expanded into the New World in a single event,” said Connie Mulligan, an associate professor of anthropology at the College of Liberal Arts and Sciences and assistant director of the UF Genetics Institute.

London, Feb 13: Scientists have discovered the fossils of a new species of dinosaur in Mexico,

Washington, Feb 13: Archaeologists have found the earliest evidence ever discovered of an ancient Egyptian agricultural settlement.

Discovered by Archaeologists from UCLA (University of California, Los Angeles) and the University of Groningen (RUG) in the Netherlands, the findings included farmed grains, remains of domesticated animals, pits for cooking and floors for what appear to be dwellings.

None of the varieties of domesticated animals or grains are indigenous to the area, so they would have to have been introduced.

The findings, which were unearthed in 2006 and are still being analyzed, also suggest possible trade links with the Red Sea, including a thoroughfare from Mesopotamia, which is known to have practiced agriculture 2,000 years before ancient Egypt.
