ENORMOUS EVOLUTIONARY GAP. "This Botanical Briefing reviews how the integration of palaeontology, geochemistry and developmental biology is providing a new mechanistic framework for interpreting the 40- to 50-million-year gap between the origination of vascular land plants and the advent of large (megaphyll) leaves, a long-standing puzzle in evolutionary biology." http://aob.oxfordjournals.org/content/96/3/345.full.pdf View in LinkedIn

MEMORY ENGINE. “Dr. Gary Marcus, a psychology professor at New York University, tells Big Think that we should develop a "Google-like" chip to implant in our brains that would use our neurons like a search engine and enhance human memory.” https://lnkd.in/dZVxp_b View in LinkedIn

READING THE SIGNALS. “Today, effective brain-machine interfaces have to be wired directly into the brain to pick up the signals emanating from small groups of nerve cells. But nobody yet knows how to make devices that listen to the same nerve cells that long.” https://lnkd.in/dSnTTfk View in LinkedIn

SIGNAL ALGORITHM. “Researchers asked 12 people with epilepsy to look at pictures and then recall up to 90 seconds later which ones they had seen. While the participants did this, the researchers recorded the firing patterns in both CA3 and CA1. They then developed an algorithm that could use the activity of the CA1 cells to predict the pattern that was coming from CA3. Compared with the actual patterns, their predictions were accurate about 80% of the time.” http://www.nature.com/news/memory-boosting-devices-tested-in-humans-1.18712 View in LinkedIn
