Biology blurs line between sexes, behaviors

Biological sex is typically understood in binary terms: male and female. However, there are many examples of animals that are able to modify sex-typical biological and behavioral features and even change sex. A new study, ...

New technique reveals unseen information in DNA code

Imagine reading an entire book, but then realizing that your glasses did not allow you to distinguish "g" from "q." What details did you miss? Geneticists faced a similar problem with the recent discovery of a "sixth nucleotide" ...

Gelatin nanoparticles could deliver drugs to the brain

Stroke victims could have more time to seek treatment that could reduce harmful effects on the brain, thanks to tiny blobs of gelatin that could deliver the medication to the brain noninvasively.

Nanocarriers may carry new hope for brain cancer therapy

Glioblastoma multiforme, a cancer of the brain also known as "octopus tumors" because of the manner in which the cancer cells extend their tendrils into surrounding tissue, is virtually inoperable, resistant to therapies, ...

Brain tumor cells decimated by mitochondrial 'smart bomb'

An experimental drug that attacks brain tumor tissue by crippling the cells' energy source called the mitochondria has passed early tests in animal models and human tissue cultures, say Houston Methodist scientists.

You need this hole in the head—to be smart

University of Adelaide researchers have shown that intelligence in animal species can be estimated by the size of the holes in the skull through which the arteries pass.

Brain on a chip?

(PhysOrg.com) -- How does the human brain run itself without any software? Find that out, say European researchers, and a whole new field of neural computing will open up. A prototype 'brain on a chip' is already working.
