WASHINGTON (AP) -- A federal appeals court will not reconsider a decision blocking an Obama administration effort to tighten restrictions on power plant pollution.
The U.S. Circuit Court of Appeals for the District of Columbia denied the administration's request for a new hearing on Thursday. The court said a majority of its eight active judges opposed rehearing the case.
A three-judge judge panel ruled in August that the Environmental Protection Agency's cross-state air pollution rule exceeded EPA's authority. The EPA had said the rule would reduce power-plant pollution that contributes to unhealthy air in neighboring states.
The appeals court panel faulted the EPA for imposing "massive emissions reduction requirements" on upwind states without regard to limits imposed by law.
A spokeswoman for the EPA, Alisha Johnson, says the agency is reviewing the decision.

Beta-blockers offer some protection
WINSTON-SALEM, N.C. Jan. 25, 2013 Not surprisingly, a cancer diagnosis creates stress. And patients with prostate cancer show higher levels of anxiety compared to other cancer patients.
A new study by researchers at Wake Forest Baptist Medical Center indicates that stress is not just an emotional side effect of the diagnosis; it also can reduce the effectiveness of prostate cancer drugs and accelerate the development of prostate cancer.
The findings are published in the February issue of the Journal of Clinical Investigation.
The Wake Forest Baptist team, headed by George Kulik, D.V.M., Ph.D., associate professor of cancer biology, tested the effects of behavioral stress in two different mouse models of prostate cancer.
One model used mice that were implanted with human prostate cancer cells and treated with a drug that is currently in clinical trial for prostate cancer treatment. When the mice were kept calm and free of stress, the drug destroyed prostate cancer cells and inhibited tumor growth. However, when the mice were stressed, the cancer cells didn't die and the drug did not inhibit tumor growth.
In the second model, mice genetically modified to develop prostate cancer were used. When these mice were repeatedly stressed, the size of prostate tumors increased. When the mice were treated with bicalutamide, a drug currently used to treat prostate cancer, their prostate tumors decreased in size. However, if mice were subjected to repeated stress, the prostate tumors didn't respond as well to the drug.
After analyzing the data, the Wake Forest Baptist researchers identified the cell signaling pathway by which epinephrine, a hormone also known as adrenaline, sets off the cellular chain reaction that controls cell death. Considering that prostate cancer diagnosis increases stress and anxiety levels, stress-induced activation of the signaling pathway that turns off the cell death process may lead to a vicious cycle of stress and cancer progression, Kulik said.
Yet in both models in which the mice were given beta-blocker, stress did not promote prostate tumor growth. Beta-blocker is a drug that inhibits the activation of anti-death signaling by epinephrine.
"Providing beta-blockers to prostate cancer patients who had increased epinephrine levels could improve the effectiveness of anti-cancer therapies," Kulik said. "Our findings could be used to indentify prostate cancer patients who will benefit from stress reduction or from pharmacological inhibition of stress-inducing signaling."
The researchers now plan to test the same signaling mechanism that was identified in mice to determine if it also works in the same way in human prostates, Kulik said.
"We are at the very beginning of understanding complex stress-cancer interactions with multifaceted responses to stress that affect cancer cells, tumor microenvironment, and the organism overall," he said. "We hope that components of this signaling pathway could be used as biomarkers to predict whether and how a given tumor will respond to stress and anti-stress therapies."

The Cloud Save feature of Xbox was not working last weekend and many users ended up with a woe for Xbox. Well, if you are one of such Xbox users, Microsoft get your pain now by apologizing for the outage and paying a compensation for the same.
Microsoft is giving out free one-month extension for Xbox Live Gold Accounts as a compensation of Cloud Save outage during last week.
Microsoft however has fixed the entire technical issues and the Xbox Cloud Save is back in function from this weekend.
Major Nelson from Microsoft sent out a special apology message for the users who suffered the Cloud Save outage saying ? To Microsoft, I say, ?Top-notch apology. Yes quite.? And to the Xbox Live Team, I say, ?Now go and rest our heroes.?
?The company will be offering a complimentary month of Xbox Live Gold membership to ?all? affected users?.
On the same note, Alex Garden, general manager of Xbox Live, said ?We want to thank all of our Xbox Live members impacted by the Cloud Saved Games service issue for your patience and understanding. It took longer than we expected to get back to full performance as we needed to ensure the integrity of everyone?s game saves?.
?Whether you couldn?t access your game saves for a couple of hours or a couple of days, we sincerely apologize for the delay and inconvenience. We will be automatically applying a one-month extension to the Xbox Live Gold memberships of everyone who was impacted. We can assure you we?ll also be doing a thorough post mortem to help prevent this from happening again.?
Many services on Xbox.com and Xbox Live were affected by this technical issue. Xbox team posted on their official twitter page last week that Cloud Save service is not working properly and the users were unable to access their save files.
Fortunately the issue?didn?t?hit every Xbox Live user and it is fixed by now.

House Minority Leader Nancy Pelosi has said the President should use the 14th Amendment of the Constitution to circumvent a?stubborn House of Representative who want to control spending and not raise taxes any more than they already have been.
All this craziness is quite distracting for both sides but there is one question that has not been asked and the Press needs to have the guts to ask it of the President and all the other Congressmen that want to keep deficit spending.
The question for the President is this:
What is the most the US Government can go into debt?
The debt ceiling keeps getting raised but no one says what is the most the US Federal Government can go into debt. ? ?All the great minds on Wall Street and in Washington DC have never answered this question.
Any business or organization knows where its maximum debt limit is. ?Even a private citizen has a debt limit when they go to buy a house. ?Debt to income ration can make or break a house sale.
So if they can figure it out the average Joe why can?t they figure it our for government?
There has to be a limit and the powers to be in Washington know it. ?Have we surpassed it or are we almost there.
Someone needs to ask the President before it is too late.
