Friday, 06 May 2016 — Snow job

They do not look like this

Many researchers think that the iconic images of snow flakes are fake. Super fast imaging does show something quite different.

Thursday, 05 May 2016 — Big data tracks our environment

In both the fMRI imaging and the microscopic imaging we saw the last two days a major achievement was making sense of big data and creating visualizations to show the meaning. Advances in imaging give us huge amounts of data to be mined for meaning. One approach is to create a new business putting big data into useful forms. Our videos today show this approach by a company tracking our environment and a company tracking illegal fishing.

Often mining big data is just one step toward obtaining useful results. Here this step is a cost and not a business opportunity. For example, we have monster data sets of weather data which must be studied to find meaningful results to use in models which can predict environment changes. An approach here is for citizen scientists to study the data and find those meaningful results.

We are better at spotting meaning than computers. We are more plentiful. We are less expensive. And, we enjoy being helpful. We will do this.

Wednesday, 04 May 2016 — Microscopic brain imaging

The fMRI imaging we saw yesterday shows us extra blood in a brain where something is happening. But, what is happening there? We do not know. We do not have a complete view of brain parts and of connections among those parts. Our first video today shows a way to get a better microscopic picture. As we move through the 3D image it looks like the parts are moving. They are not. We are moving.

Our second video today shows the impressive result — a full 3D microscopic image of tiny portion of a mouse brain — published mid-2015.

This work was published 30 Jul 2015 in Cell, a top peer reviewed journal. The on-line publication includes a video abstract telling more about meanings of the result.

We saw trustworthy science give us trustworthy evidence. We saw reliable and sensitive imaging. We have less uncertainty about brain structure and new mysteries about brain connections. We saw persons with diverse skills sets and diverse points of view share the work.


Tuesday, 03 May 2016 — fMRI mapping ideas or words or something in brains

We start today watching a brain listening to "Adios Nonino," a Tango Nuevo by Astor Piazzolla. The research producing this video was published in Science a top peer reviewed journal.

Brain listening to tango [video link] [mp4 version]

Those brain on tango images were obtained by functional magnetic resonance imaging (fMRI). In MRI magnetic moments of nuclei of atoms (Hydrogen for example) in the brain, aligned by a very strong magnetic field, are caused to resonate between energy states. Energy emitted when nuclei change energy state is detected. In fMRI parts of a brain engaged in the function get more blood (which is mainly water) so that energy signal from those parts is greater. After much computation an image is formed showing parts of the brain getting greater blood (red in our tango video).

In our tango video that function was listening to tango. In our next vdeos that function is thinking about words, or ideas, or something else. Our next video is by Nature Publishing Group, a for-profit publisher. Nature is a top peer reviewed journal.

Our last video is by our National Science Foundation which funded this research. The "Science Nation" series of NSF videos toots the NSF horn by showing how basic science gives us useful results. We also have a link to an NSF story about the research.

These two videos give us great opportunities to ask questions relevant to making our recommendations about the videos and about the work.


Monday, 02 May 2016 — Imaging and data visualization

Earth Rise by Apollo 8, 24 Dec 1968

When — nearly 50 years ago now — we saw this view of Earthrise taken by the crew of Apollo 8 orbiting our Moon we saw our Earth a new way. Many of us were moved to recharge our commitment to good stewardship of our planet.

Another story which unfolded over those 50 years is the story of huge improvements in imaging and in data visualization. At every wavelength of light from the highest energy gamma rays through visible to long radio waves we have ever more sensitive imaging means. We have ever more sensitive means for imaging with sound and magnetic resonance. We just succeeded in detecting gravity waves.

Along with those great improvements in imaging we had great improvements in visualizing the data. This is thanks to our great increases in computing power and thanks to very clever software. Today we start with some iconic visual images, explore kinds of imaging from space, and are treated to NASA showing off data visualization.
