Where in the Brain does Creativity come from? Evidence from Jazz Musicians

Brain activity maps showing areas associated with high-creativity performances compared with lower-creativity performances. Each map shows a top view of the head.

A new brain-imaging study has studied the brain activity of jazz guitarists during improvisation to show that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, musicians who are highly experienced at improvisation rely primarily on their left hemisphere.

This suggests that creativity is a “right-brain ability” when a person deals with an unfamiliar situation but that creativity draws on well-learned, left-hemisphere routines when a person is experienced at the task.

By taking into consideration how brain activity changes with expe...

3D-Printed Corals could Improve Bioenergy and help Coral Reefs

Daniel Wangpraseurt et al. ‘Bionic 3D printed corals.’ Nature Communications (2020). DOI: 10.1038/s41467-020-15486-4

Researchers from Cambridge University and University of California San Diego have 3D printed coral-inspired structures that are capable of growing dense populations of microscopic algae. Their results, reported in the journal Nature Communications, open the door to new bio-inspired materials and their applications for coral conservation.

In the ocean, corals and algae have an intricate symbiotic relationship. The coral provides a host for the algae, while the algae produce sugars to the coral through photosynthesis. This relationship is responsible for one of the most diverse and productive ecosystems on Earth, the coral reef.

“Corals are highly efficient at co...

In a first, NASA measures Wind Speed on a Brown Dwarf

This artist’s concept shows a brown dwarf, an object that is at least 13 times the mass of Jupiter but not massive enough to begin nuclear fusion in its core, which is the defining characteristic of a star. Scientist using NASA’s Spitzer Space Telescope recently made the first ever direct measurement of wind on a brown dwarf.

For the first time, scientists have directly measured wind speed on a brown dwarf, an object larger than Jupiter (the largest planet in our solar system) but not quite massive enough to become a star. To achieve the finding, they used a new method that could also be applied to learn about the atmospheres of gas-dominated planets outside our solar system.

Described in a paper in the journal Science, the work combines observations by a group of radio telescopes w...

Repairing Stroke-Damaged Rat Brains

Researchers at Lund University in Sweden have succeeded in restoring mobility and sensation of touch in stroke-afflicted rats by reprogramming human skin cells to become nerve cells, which were then transplanted into the rats’ brains. The study has now been published in the Proceedings of the National Academy of Sciences (PNAS).

“Six months after the transplantation, we could see how the new cells had repaired the damage that a stroke had caused in the rats’ brains,” says Professor Zaal Kokaia, who together with senior professor Olle Lindvall and researcher Sara Palma-Tortosa at the Division of Neurology is behind the study.

Several previous studies from the Lund team and others have shown that it is possible to transplant nerve cells derived from human stem cells or from reprog...
