Data showed that hunter-gatherer populations in the region had the greatest degree of genetic diversity, which is an indicator of longevity.
It says that the region was probably the best location for the origin of modern humans, challenging the view that we came from eastern Africa.
The study appears in the Proceedings of the National Academy of Sciences. "Africa is inferred to be the continent of origin for all modern human populations," the international team of researchers wrote. "But the details of human prehistory and evolution in Africa remain largely obscure owing to the complex histories of hundreds of distinct populations."

SHOCK: Increased Export of Brazilian Beef Indirectly Leads to Deforestation in Amazon
From Science Daily: Increased export of Brazilian beef indirectly leads to deforestation in the Amazon. New research from Chalmers and SIK in Sweden that was recently published in Environmental Science & Technology shows that impact on the climate is much greater than current estimates indicate. The researchers are now demanding that indirect effect on land be included when determining a product's carbon footprint.

NASA Technology 1st Developed for Plant Growth Experiments, Successfully Reduces Painful Side Effects from Chemo & Radiation
From Science Daily:
A NASA technology originally developed for plant growth experiments on space shuttle missions has successfully reduced the painful side effects resulting from chemotherapy and radiation treatment in bone marrow and stem cell transplant patients.CLICK HERE to read the entire article. This is fascinating information that could go a long way in reducing the painful side effects patients who are undergoing chemotherapy and radiation experience!
In a two-year clinical trial, cancer patients undergoing bone marrow or stem cell transplants were given a far red/near infrared Light Emitting Diode treatment called High Emissivity Aluminiferous Luminescent Substrate, or HEALS, to treat oral mucositis -- a common and extremely painful side effect of chemotherapy and radiation treatment. The trial concluded that there is a 96 percent chance that the improvement in pain of those in the high-risk patient group was the result of the HEALS treatment.

Scientists Discover Malignant Cancer-Causing Molecule
I came across an interesting article on the Environmental News Network detailing how scientists at the University of Montreal's Department of Biochemistry and the University of Montreal Hospital Research Centre identified a molecule known as PML, which directly affects whether or not a cancer cell become malignant. This may be a breakthrough in cancer research if scientists are able to ascertain how malignant tumors can be converted to benign tumors. The team was led by Dr. Gerardo Rebeyre of the University of Montreal.
Read published article: http://genesdev.cshlp.org/content/25/1/41.abstract
"We discovered that benign cancer cells produce the PML molecule and display abundant PML bodies, keeping them in a dormant, senescent state. Malignant cancer cells either don't make or fail to organize PML bodies, and thus proliferate uncontrollably," said Ferbeyre.
A dormant, senescent state is one in which the cell has matured and is no longer able to reproduce. PML is the body's natural defense against the cancer spreading to other cells and other parts of the body. Previously, the mechanism for how PML worked was a mystery. However, the team’s research has managed to shine a light on it by collecting samples from hospital patients.
"Our findings unravel the unexpected ability of PML to organize a network of tumor suppressor proteins to repress the expression or the amount of other proteins required for cell proliferation," explained researcher VĂ©ronique Bourdeau. Researcher Mathieu Vernier emphasized that "this is an important finding with implications for our understanding on how the normal organism defends itself from the threat of cancer."

Alaska Pipeline Shut Down After Leak Discovered at Intake Pump Station at Prudhoe Bay
(Reuters) - The Trans Alaska Pipeline shut down on Saturday after a leak was discovered at the intake pump station at Prudhoe Bay, constricting supply in one of the United States' key oil arteries. Alyeska Pipeline Service Co., the operator of the 800-mile (1,280 kilometre) line which runs from the Prudhoe Bay oilfield to the tanker port of Valdez, said the leak was discovered Saturday morning. Oil producers are in the process of cutting output to 5 percent of the normal rate of around 630,000 barrels per day. There is no estimate yet of how long the pipeline -- which carries about 12 percent of U.S. oil production -- will be shut down or when normal production can resume, said Alyeska spokeswoman Michelle Egan.

Tens of Thousands of Dead Crabs Litter Thanet Coast in the UK
The Thanet Coast in the United Kingdom is littered with thousands of dead crabs. According to the Huffington Post, the BBC notes that this is the third year in a row thousands of dead devil crabs, also known as velvet swimming crabs, have turned up on the coastline near Kent, England. It is estimated that 40,000 of the dead crabs have washed up on the beaches this year.

Thousands of Dead Fish Found on Shores in Calvert County & Kent Island May have Died Due to Stress of Cold Water in Chesapeake Bay
From WBAL11.com:
The Maryland Department of the Environment said that tens of thousands of small fish have died in the Chesapeake Bay due to the stress of the cold water.
MDE spokeswoman Dawn Stolzfus said reports of a fish kill started coming in last week from Calvert County and Kent Island.
Many 11 News viewers wrote in Monday to report that the fish had begun washing onto the shore.
Stolzfus said the types of fish that have died are menhayden, spots and croakers.
She said the fish usually swim to warmer waters before the severe cold weather that the area experienced in December. There is no word on why the fish didn't do that.

Hundreds of Dead & Dying Red-Winged Blackbirds Cover Quarter Mile Stretch of Louisiana Highway
SHOCK: Hundreds of dead and dying red-winged blackbirds have littered a quarter-mile stretch of a highway in Pointe Coupee Parish on Monday, according to 2theadvocate.com. This comes in the aftermath of nearly 3,000 red-winged blackbirds falling from the skies over Beebe, Arkansas.
State biologists are trying to determine what led to the deaths of the estimated 500 red-winged blackbirds and starlings on La. 1 just down the road from Pointe Coupee Central High School.This is shocking and it seems to be happening to one specie of birds. According to the Associated Press, the necropsies performed Monday on the birds in Arkansas showed the birds suffered internal injuries that formed blood clots leading to their deaths.
The discovery of the dead birds — some of which were lying face down, clumped in groups, while others were face up with their wings outstretched and rigid legs pointing upward — comes just three days after more than 3,000 blackbirds rained down from the sky in Beebe, Ark.

California Farmworkers Challenging Approval of State-Listed Carcinogen, Methyl Iodide, on Strawberry Fields
From the Los Angeles Times:
A group of environmental and community health organizations is challenging the state’s approval late last month of the agricultural fumigant methyl iodide, a state-listed carcinogen. The coalition representing farmworkers and environmental groups charges that the California Department of Pesticide Regulation fast-tracked the registration of methyl iodide, and then invoked an emergency regulation to avoid legally mandated public hearings. The fumigant, used by strawberry growers to prepare soil, was approved on Dec. 20 and designated a restricted material, requiring a permit from a county agricultural commission.Read more: Farmworkers challenge approval of methyl iodide on strawberry fields | LA Times

Brazil Expects Oil Output to More Than Double in 10 Years
From Bloomberg News:
Brazil aims to more than double oil output in the next 10 years as part of 1 trillion reais ($604 billion) of energy investments expected for the period, Energy Minister Edison Lobao said today. The country’s oil output will rise 161 percent, Lobao told reporters in Brasilia today. Brazil produced a record 2.5 million barrels a day of oil and natural gas in November, according to government data. The country plans to auction licenses for its so-called pre-salt deepwater reserves in the second half, he said.
Petroleo Brasileiro SA, Brazil’s state-run oil producer, plans to spend $224 billion in the five years through 2014, the industry’s biggest investment program. Foreign oil companies including Royal Dutch Shell Plc and Chevron Corp. are also increasing production in the country as they develop offshore oil fields.
Petrobras investments include tapping the Lula field, formerly known as Tupi, the second-largest find in the Americas since Mexico discovered Cantarell in 1976. Libra, the largest, will be part of the first pre-salt auction this year.
