Homosexuality in yeast (pp 890-893; N&V)
The human pathogen Candida albicans can reproduce by a previously unappreciated route, a Nature paper reveals. Until recently, the infection-causing yeast was thought to be strictly asexual, but then sexual reproduction was observed between cells of different sexes. Richard Bennett and colleagues now show that, in certain circumstances, sexual reproduction can also occur between cells of the same sex. This mode of reproduction occurs when a gene encoding a secreted protease enzyme is lacking. The study indicates a role for specialized sexual cycles in the survival and adaptation of disease-causing fungi.

Great Barrier Reef
CANBERRA (Reuters) - Australia's Great Barrier Reef, the world's largest living organism, is under grave threat from climate warming and coastal development, and its prospects of survival are "poor," a major new report found on Wednesday.
"Even with the recent management initiatives to improve resilience, the overall outlook for the Great Barrier Reef is poor and catastrophic damage to the ecosystem may not be averted," a government reef management body said in the report.
The five-yearly reef outlook report, aimed at benchmarking the health of the reef, found climate change, declining water quality from coastal runoff, development and illegal fishing were the biggest dangers to the reef.
The study echoed findings by scientists belonging to the U.N. Intergovernmental Panel on Climate Change that the Great Barrier Reef could be "functionally extinct" within decades, with deadly coral bleaching likely to be an annual occurrence by 2030.

EAT-September
I am going to start a new blog feature :)
Every month I am going to research what vegetables/fruits are fresh that month and an easy recipe to make with them. The highlighted items will be a link to that recipe. I will do my best to overlap ingredients to maximize meals.
This should lower the cost of the groceries and increase the nutrients of the produce.
These items will also be readily available at your local farmers market
Hope you enjoy.

Obesity & Brain Degeneration
A new study finds obese people have 8 percent less brain tissue than normal-weight individuals. Their brains look 16 years older than the brains of lean individuals, researchers said today. Those classified as overweight have 4 percent less brain tissue and their brains appear to have aged prematurely by 8 years.
"That's a big loss of tissue and it depletes your cognitive reserves, putting you at much greater risk of Alzheimer's and other diseases that attack the brain," said Paul Thompson (ACLU). "But you can greatly reduce your risk for Alzheimer's, if you can eat healthily and keep your weight under control."
The findings are detailed in the online edition of the journal Human Brain Mapping.
More than 300 million worldwide are now classified as obese, according to the World Health Organization. Another billion are overweight. The main cause, experts say: bad diet, including an increased reliance on highly processed foods.
Obesity is measured by body mass index (BMI), defined as the weight in kilograms divided by the square of the height in meters. A BMI over 25 is defined as overweight, and a BMI of over 30 as obese.
