Center for Food Safety, a controversial litigation group that has been shown on numerous occasions to be conspiring to manipulate the public about American agriculture, is in the news again. This time for paying former Democratic Congressman, former race-baiting Cleveland mayor, and current Ohio gubernatorial candidate Dennis Kucinich to promote organic food and products by undermining the competitors of CFS clients.

It sounds gross to humans - unless you read those "Twilight" books in which case maybe it's sexy - but a lot of animals consume blood.  That's right, even your cat familiar. 

The question is why? Blood is actually a poor source of energy. It consists of 78 percent liquid and what is left is 93 percent proteins and only one percent carbohydrates (1). Blood provides very little in the way of vitamins. Not only that, a blood-based diet exposes animals to blood-borne pathogens.

And yet some bat species (order Chiroptera) feed exclusively on blood and have managed to survive evolution that should have killed them, and their reliance on low-grade nourishment, off.

Many people are addicted to a stimulant. Lawyer-driven groups like Center for Science in the Public Interest have long wanted to sue coffee companies over caffeine but haven't gained much traction despite their efforts to claim it causes things like breast cancer.

If you offer a wealthy elite any fish that is not gathered by depleting the oceans, they will recoil in horror. It is unclear why they recognize that farms are essential for growing vegetables but think farmed fish should only be for the poor. 

The science says otherwise. Aquatic farming -- aquaculture -- can help feed the future global population while substantially reducing one of the biggest environmental impacts of protein production -- land use -- without requiring people to entirely abandon protein as a food source.

The South Atlantic Anomaly has people concerned, but if Earth's magnetic field of the past is any indication, and it is, the anomaly is not a precursor of a switching of the poles.

What is the South Atlantic Anomaly?

Last week, the National Institute of Environmental Health Sciences (NIEHS) in Research Triangle Park, North Carolina held a meeting to discuss the results of a 30-million-dollar fede

Visual observation of the planets of our solar system has always been an appealing pastime for amateur astronomers, but the digital era has taken away a little bit of glamour to this activity. Until 30 years ago you could spot with your eye more detail than was at reach of normal photography even for large telescopes, so amateur astronomers could contribute to planetary science by producing detailed drawings of the surface of Jupiter, Saturn, Venus, and Mars. 

This is another of those sensationalist doomsday stories in the red top tabloids scaring people. The stories say that we are 100% certain to be hit by an asteroid. Well, yes, for small asteroids, but we are 100% certain to be hit by lightning too, many times a year. Your chance of dying of an asteroid impact is far less than that of dying of a lightning strike, 10,000 times less likely.

The dancer, actress, director and photographer Helene “Leni” Riefenstahl, who died in 2003, is a controversial character, largely because of the many propaganda movies she produced for the Nazis. So when it was recently announced that her estate would be handed over to a Berlin photography museum, historians of the period hoped to find some clarification about the extent of her involvement with the Nazi regime.
