The best quote is not from the article but from a comment.
The closest experience that most researchers have with the concept of Open Access is indeed Open Source Software, and the most common forms of OSS licences with Copyleft. This intuitively works for many researchers – the idea that they are happy to provide the output of their research for use to anyone as long as those people do likewise. On the other hand, the idea that we should provide our research output free for corporations to redistribute and profit from is something that a huge number, possibly a majority, of researchers would be thoroughly against.

A comprehensive approach to zinc-finger recombinase customization enables genomic targeting in human cells
by
Gaj T, Mercer AC, Sirk SJ, Smith HL, Barbas CF
"Zinc-finger recombinases (ZFRs) represent a potentially powerful class of tools for targeted genetic engineering. These chimeric enzymes are composed of an activated catalytic domain derived from the resolvase/invertase family of serine recombinases and a custom-designed zinc-finger DNA-binding domain. The use of ZFRs, however, has been restricted by sequence requirements imposed by the recombinase catalytic domain. Here, we combine substrate specificity analysis and directed evolution to develop a diverse collection of Gin recombinase catalytic domains capable of recognizing an estimated 3.77 × 10(7) unique DNA sequences. We show that ZFRs assembled from these engineered catalytic ... more »

New research brings light to star mystery
Scientists at Northumbria University have begun to unlock the mystery of why the outer edge of the Sun is much hotter than its surface for the first time.

Magnetic loop structures in the corona of the Sun. The loops highlight the Sun’s magnetic field and are visible because they support the dense, million degree gas typical of the corona. The image is courtesy of the Science Team for NASA’s Solar Dynamic Observatory.

DNA Analysis Reveals Common Origin of Tianyuan Humans and Native Americans, Asians
An international team of scientists has sequenced nuclear and mitochondrial DNA extracted from remains of a 40,000-year-old human found at the Tianyuan Cave site near Beijing, China. The results show Tianyuan humans shared a common origin with ancestors of many present-day Asians and Native Americans.
Humans with morphology similar to present-day humans appear in the fossil record across Eurasia between 40,000 and 50,000 years ago. The genetic relationships between these early modern humans and present-day human populations had not yet been established.
The team, including Dr Svante Pääbo and Dr Qiaomei Fu from the Max Planck Institute for Evolutionary Anthropology, extracted nuclear and mitochondrial DNA from a leg bone found in 2003 at the Tianyuan Cave site, located outside Beijing.
