Cutting carbon dioxide emissions is not easy; it requires a buy-in from developing nations who have coal and want a better life also, or a greater implementation of natural gas. One alternative idea is to transport materials into the stratosphere to reduce the amount of sunlight hitting Earth and therefore reduce the effects of global climate change.

A new paper says that the basic technology currently exists and could be assembled and implemented in a number of different forms for less than $5 billion a year - a tiny fraction of the amount that cutting emissions costs. Put into context, the cost of reducing carbon dioxide emissions is currently estimated to be between 0.2 and 2.5 per cent of GDP in the year 2030, which is equivalent to $200 billion to $2 trillion.

Women who have breast cancer and are treated with two chemotherapy drugs, anthracycline and trastuzumab, may experience more cardiac problems like heart failure than shown in previous studies, according to a new Cancer Research Network study by Group Health researchers and others in the Journal of the National Cancer Institute.

Researchers have found that a human monoclonal antibody developed by MassBiologics of the University of Massachusetts Medical School (UMMS) protected chimpanzees from hepatitis C virus (HCV) infection in a dose-dependent manner.

The study was conducted at Texas Biomed's Southwest National Primate Research Center.  Chimpanzees are the only species other than humans that can be infected by HCV and therefore the results from this study were critical in the development of the monoclonal antibody.  

Social security is in a crisis even worse than Medicare. Because Congress has consistently spent contributions, social security is always on the edge of insolvency and now that the Baby Boomers have begun retiring, the crisis is going to get worse, with not enough workers to fund the retirees.

Ideas such as raising the retirement age are floated by University of Michigen economists have a more positive approach; they say if we stop collecting social security payroll taxes when workers are 55-years old, their take-home pay would jump by 10.6 percent, older people would work 1.5 years longer on average and end up still paying more in income taxes and helping to reduce the Federal deficit while not drawing retirement.

A large study published in Human Reproduction (1) looked at the effect of induced abortions on a subsequent first birth and found that women who have had three or more abortions have a higher risk of adverse birth outcomes, such as delivering premature and low birth weight babies.

Analysis of the abdominal contents of two dinosaur fossil specimens reveals new information about their hunting and eating behavior, according to a new report.  They may have been stealth hunters.
