So here’s something you don’t see everyday. Blu-ray disks, you know the stuff we use for video games or DVDs also improve the performance of solar cells—suggesting a second use for unwanted discs—according to new research from Northwestern University. As surprising as this was, there is even better news, we know why they improve performance.... Read more »

The turkey is an amazing bird, beyond it’s taste on Thanksgiving. It has some really funky structures on its head, like the caruncles, wattle and snood, but research shows that they are important in mate selection. The question is why they have been retained even though they are artificially bred nowadays. Maybe they are for more than just mate selection. And yes....turkeys can fly.... Read more »

The paper by Pagan and colleagues  (open-access) looking at "serotonin, melatonin and the intermediate N-acetylserotonin (NAS) in a large cohort of patients with ASD [autism spectrum disorder] and their relatives" set the old grey-pink matter into action recently.

When choosing a restaurant for a dinner with friends we need to combine information prior to decision, concerning the location, menu, and price range. Similarly, when crossing a busy road, we sometimes need to integrate information from multiple sources, such as horn sounds and the sight of approaching cars. A recent paper published by myself and colleagues does not tell you which restaurant to choose for your party or how to safely cross the road. Rather, it provides a means for evaluating how ........

The fight against HIV is ongoing and despite our rapid progression against the disease we still lack a cure or even adequate treatment for people infected. However, new research suggests that cloaking immune cells with antibodies that block T cell trafficking to the gut can substantially reduce the risk of viral transmission, at least in a non-human primate model of HIV infection. If it works out, this could help slow down the spread of HIV and give people a better shot at a normal life.... Read more »

Our clients are routinely stunned by the accuracy of mock juror impressions of witnesses and parties based on a 6 to 8 minute video clip from depositions.

Most kids worry about passing tests, winning games, lost phones, fractured bones—and whether or not they will ever really fall in love. While the first few things are of relatively low value in the scientific pursuit, three Chinese researchers have focused on that last question.

A new study finds that habitual use of Facebook makes individuals susceptible to social media phishing attacks by criminals, likely because they automatically respond to requests without considering how they are connected with those sending the requests, how long they have known them, or who else is connected with them.
