A few degrees of ocean warming could leave octopuses unable to see, according to a new study by researchers at the University of Adelaide, Australia and 51�ԹϺ�� Davis. Embryo octopus raised in warmer waters lacked proteins essential to vision and had a high mortality rate.

New Technology Solves Mystery of Respiration in Tetrahymena

Tetrahymena, a tiny single celled-organism, turns out to be hiding a surprising secret: it’s doing respiration – using oxygen to generate cellular energy – differently from other organisms such as plants, animals or yeasts. The discovery, published March 31 in Science, highlights the power of new techniques in structural biology and reveals gaps in our knowledge of a major branch of the tree of life.

Forensic Proteomics, a New Tool for Crime Labs and Anthropology

DNA evidence has revolutionized forensic science in the past few years, cracking open cold cases and bringing both convictions and exonerations. The same techniques help archaeologists and anthropologists studying remains from ancient peoples or human ancestors.

But DNA is a relatively fragile molecule that breaks down easily. That’s where proteomics, the new science of analyzing proteins, comes in. By reading the sequence of amino acids from fragments of protein, scientists can work backwards to infer the sequence of DNA that produced the protein.
