Dogs imitate, but don't ape

post from Science Blog - Science News: Think. It's not illegal yet. on 26 April 2007 01:58:46 PM. © Science Blog - Science News: Think. It's not illegal yet.

A distinguishing feature of human intelligence is our ability to understand the goals and intentions of others. This ability develops gradually during infancy, and the extent to which it is present in other animals is an intriguing question. New research reveals striking similarities between humans and dogs in the way they imitate the actions of others.

Integrating transplanted nerve cells into injured
tissue

post from Science Blog - Science News: Think. It's not illegal yet. on 26 April 2007 01:56:37 PM. © Science Blog - Science News: Think. It's not illegal yet.

Scientists have identified a key mechanism for successfully transplanting tissue into the adult central nervous system. The study found that a molecule known as MMP-2 (which is induced by stem cells) has the ability to break down barriers on the outer surface of a damaged retina and allow healthy donor cells to integrate and wire themselves into remaining recipient tissue.

Happy ending

post from Aetiology on 26 April 2007 01:55:00 PM. © Aetiology

If you've been reading Scienceblogs over the last 24 hours or so, you've probably seen reference to Shelley's legal issues regarding Wiley publishing and their accusation that her use of one panel of one figure of a scientific paper violated copyright. Well, after the story was featured at Boing Boing and elsewhere around the blogosphere, Wiley has now apologized:

"We apologise for any misunderstanding. In this situation the publisher would typically grant permission on request in order to ensure that figures and extracts are properly credited. We do not think there is any need to pursue this matter further."

What constitutes "fair use" of scientific material has long been a thorny issue, especially in the blogosphere, so it's good to know that at least in this case, the publisher agrees that the original use would have been fine. However, as noted in the comments, the publisher still mentions "permission on request"--so they're still not giving carte blance for use of their figures. Still, it's better than a lawsuit threat against a graduate student...

Deciphering the Science in Science News Reports

post from Science Blog - Science News: Think. It's not illegal yet. on 26 April 2007 01:04:06 PM. © Science Blog - Science News: Think. It's not illegal yet.

Science news stories share breakthroughs and discoveries with the general public. The public learns new information, but these reports seldom help people understand HOW the discovery was made. It was recently announced that a team of researchers found no link between breast cancer and abortion. Using this news story, I shed some light on the process of science in an effort to help general audiences understand more about science in general.

When Fair Use Isn’t Fair

In her post, Antioxidants in Berries Increased by Ethanol (but Are Daiquiris Healthy?), Shelley Batts, commenting on a journal article which was written based on publicly funded research, used “ONE panel of ONE figure, and a chart, from over 10+ figures in the paper.” The for profit journal sent a threat of legal action.
