Scientists found that homosexual men have feminized brain.  They share similar brain as straight women.  The study, led by Dr. Ivanka Savid of the Karolinska Institute in Stockholm, was published in Proceedings of the National Academy of Sciences (PNAS).  This could perhaps explain why homosexual men talk and act like women.  However homosexual women did not share similar brain with heterosexual men.

So gay men are just women soul trapped in men body?

Kalmar University researchers discovered that ocean bacteria are capable of taking up carbon dioxide with the help of sunlight. Jaron Pinhassi and Laura Gómez-Consarnau in Sweden worked with colleagues in Spain, Australia, and Russia found that a unique light-capturing pigment, proteorhodopsin, use sunlight as energy source and capture carbon dioxide. Proteorhodopsin was first discovered in 2000 (Beja et al., 2000). Proteorhodopsin can be found in nearly half of the sea bacteria. This finding showed that marine bacteria are important in climate changing. The entire article will be published in Proceedings of the National Academy of Science (PNAS) this week.

This discovery reminds me of photosynthesis, which use carbon dioxide, and water, with the help of sunlight as energy source. Photosynthesis in plants is carried out by chloroplasts. The end products are oxygen and carbohydrates.
