For the first time, a team of scientists has calculated the distribution of all light energy contained within the Milky Way, which will provide new insight into the make-up of our galaxy and how stars in spiral galaxies such as ours form. This research also shows how the stellar photons, or stellar light, within the Milky Way control the production of the highest energy photons in the Universe, the gamma-rays...

The Messier 101 has a pancake-like shape that we view face-on. This perspective shows off the spiral structure that gives it the nickname the “Pinwheel Galaxy.” Credit: NASA (http://hubblesite.org/image/2477/news_release/2009-07)

Study reveals that half of matter around us likely comes from far-flung galaxies. In a first-of-its-kind analysis, Northwestern University astrophysicists have discovered that, contrary to previously standard lore, up to half of the matter in our Milky Way galaxy may come from distant galaxies. As a result, each one of us may be made in part from extragalactic matter.

Using supercomputer simulations, the research team found a ...

New research identifies potential therapeutic intervention for memory impairment, neuroinflammation, and brain insulin resistance induced by high-fat, high-fructose diet. A study published online in The FASEB Journal, involving mice, suggests that EGCG (epigallocatechin-3-gallate), the most abundant catechin and biologically active component in green tea, could alleviate high-fat and high-fructose (HFFD)-induced insulin resistance and cognitive impairment. Previous research pointed to the potential of EGCG to treat a variety of human diseases, yet until now, EGCG’s impact on insulin resistance and cognitive deficits triggered in the brain by a Western diet remained unclear.

Exosuits can be used to improve walking after stroke. This is a critical step in de-risking exosuit technology towards real-world clinical use. Upright walking on two legs is a defining trait in humans, enabling them to move very efficiently throughout their environment. This can all change in the blink of an eye when a stroke occurs. In about 80% of patients post-stroke, it is typical that one limb loses its ability to function normally -hemiparesis...
