Rat Study Shows That Exercise Promotes Neuron Growth

Exercise makes you smarter?
>Previous research had linked physical exertion with higher levels of neuronal growth factors known as neurotrophins in the spinal cord and skeletal muscles… The scientists gave rats access to a running wheel for periods ranging from zero to seven days. When they tested cultured cells taken from the animals, they found that those from the runners grew longer extensions known as neurites and that there was a direct correlation between how far the rats ran and how long the neurites became.

Antispam framework scores Microsoft endorsement

Microsoft is merging its email Caller ID effort with SPF. DomainKeys cooperation is also in the works:

“DomainKeys is the long-term approach; SPF is the short-term approach,” Wong said. “If all goes well, we will meet in the middle and squash spammers like a bug.”

8,500 Gallons of Water for 1 Pound of Beef

A new study presented to the U.N. Commission on Sustainable Development stresses the need to produce more nutrition using less water.

>One of the key findings of the report is that today, unlike during the “Green Revolution” of the 1960s, it is consumers – not producers – who are driving global food production. With massive urbanisation and increasing wealth, food preferences are changing with significant increases in the demand for meat and dairy products. It takes 550 liters of water to produce enough flour for one loaf of bread. This is a fraction of the up to 7000 liters of water that is used in developed countries to produce 100 grams of beef.

More Mono and patents

The debate about whether patents are a risk to Mono goes on. Seth Nickell of Red Hat gives his reasoning and Miguel de Icaza of Novell responds. I’m still in the pro-Mono camp if only because I don’t think Microsoft can take the public relations hit that would come with trying to stomp on Mono.
