How Alcohol Addiction – and Abstinence – Remodel the BrainNews
Novel imaging technologies produce first whole-brain atlas at single-cell resolution, revealing how alcohol addiction – and abstinence – change neural physiology and affect previously unsuspected regions of the brain
A Bigger Hippocampus Doesn't Mean Better MemoryNews
When it comes to certain parts of the brain, bigger doesn't necessarily equate to better memory. According to a new study led by Michigan State University, a larger hippocampus, a curved, seahorse-shaped structure embedded deep in the brain, does not always reliably predict learning and memory abilities in older adults.

In 1857, the Danish naturalist Japetus Steenstrup linked the tell tales of ships being dragged to the ocean floor to the existence of the giant squid: A ten-armed invertebrate, that is credibly believed to grow up to 13 meters and weigh over 900 kg. Now, more than 160 years later, an international team of scientists have sequenced and annotated the genome of a giant squid.READ MORE
Researchers at Vanderbilt University Medical Center have published a study suggesting that brain receptors activated by marijuana can be targeted to cut stress. The scientists used a mouse model of stress in their study, where they showed that a molecule that activates the receptors could reduce anxiety-linked connections between two distinct brain areas.
Why are some porphyry deposits – formed by magmatic fluids in volcanic arcs – rich in copper while others primarily contain gold? In an attempt to answer this question, researchers investigated how the metals are accumulated during a mineralizing event.READ MORE
