Opto-OISI: imaging connections in the living brain


A new imaging technique called opto-OISI allows scientists to non-invasively visualize where specific neurons project in the living brain.

The brain’s GPS has a buddy system


In addition to encoding self location, brain cells in the rat hippocampus act like a GPS that encodes the location of other rats.

Microbial infections are a parasitic plant’s dream


Parasitic plants use quinones produced by their host to attack. Now we know that crops produce quinones as an immune response against microbial infection. How can we protect crops from both kinds of attack?

Laser melting ice-core sampler for studying climate change


This laser melting ice core sampler can determine temperature changes thousands of years ago on very fine timescale.

Scientists solve epigenetic barriers to cloning


Scientists show that two epigenetic factors improve the success rate of cloning via somatic cell nuclear transfer.
