Brain’s immune system can play role in weight gain
Weight isn’t just calories in, calories out. When mice eat a fatty diet, immune cells in their brains become inflamed. That makes the animals gain more weight.

Racial discrimination may aggravate asthma, study finds
Kids who suffer racial discrimination are more likely to develop a hard-to-treat form of asthma. New data suggest the stress of bigotry can affect the immune system, potentially making the disease worse.

What scientists hope to learn from Great American Eclipse
A solar eclipse will travel across North America on August 21. Scientists will use that opportunity to learn more about our home star.

What do animals do during a solar eclipse?
A citizen-science experiment used the Great American Eclipse of 2017 to gather the largest dataset ever of animal responses to a sun-block.

Scientists probe how an eclipse affects Earth’s atmosphere
Parts of the electrically charged layer of Earth’s atmosphere lose that charge in an eclipse. Scientists are studying how it might affect everything from GPS accuracy to earthquake prediction.
- Space
Scientists Say: Transit
When an object in space passes in front of a star and looks big enough to block out all the light, it’s an eclipse. When it’s smaller, it’s called a transit.

Can concrete conquer air pollution?
Powdered concrete could remove the sulfur dioxide and other pollutants that are spewed into the air when electric-power plants burn fossil fuels, a lab study suggests.

Many U.S. football players had brain disease, data show
The brains of more than 200 former football players were donated to science upon their deaths. Signs of severe brain trauma showed up in the vast majority.

Mild brain injury can cause bead-like swellings in brain cells
Mild head bumps cause temporary swellings — like beads in a necklace — within brain cells. If cells get enough time to heal, those “beads” will disappear.
