Sun’s Core Rotates 4X Faster than its Surface

Surprising observation might reveal what the sun was like when it formed. The sun’s core rotates nearly 4X faster than the sun’s surface, according to new findings by an international team of astronomers. Scientists had assumed the core was rotating like a merry-go-round at about the same speed as the surface. “The most likely explanation is that this core rotation is left over from the period when the sun formed, some 4.6 billion years ago,” said Roger Ulrich, a UCLA professor emeritus of astronomy, who has studied the sun’s interior for more than 40 years...

Resistance Training may Slow down the Progression of MS

Image result for Resistance training in multiple sclerosis

Can resistance training impact MRI outcomes in relapsing-remitting multiple sclerosis? Multiple Sclerosis Journal, 2017; 135245851772264 DOI: 10.1177/1352458517722645

New research shows that resistance training protects the brain in persons with multiple sclerosis, which may delay the development of the disease. In the past, multiple sclerosis patients were advised not to exercise for fear of exacerbating the illness. However, it is now known that physical training can relieve many of the symptoms, including the excessive fatigue and mobility impairments that are often seen. New research now shows that resistance training may protect the nervous system and thus slow the progression of the disease.

This is the main finding of a study conducted by Aarhus University, Aarhus University Hospita...

A new material could form a new antibacterial surface that prevents infections and reduces our reliance on antibiotics, suggests new research. By some estimates, bacterial strains resistant to antibiotics – superbugs – will cause more deaths than cancer by 2050...

Engineers Produce Long Lasting, Energy Density Battery

manganese dioxide-zinc battery

A look inside the energy density manganese dioxide-zinc battery developed at CCNY

A new generation of manganese dioxide-zinc batteries with unprecedented cycle life and energy density is the latest innovation at The City College of New York-based CUNY Energy Institute. The discovery has made the common household battery suitable for large grid Storage applications. City College Snr Research Associate Gautam G. Yadav and his team applied a new twist to the old chemistry behind batteries. The result is a battery that takes advantage of intercalation and complexation chemistry to make the cathodes rechargeable to a larger extent, greatly extending its life.

“A new layered crystal structure of manganese dioxide is used in this chemistry, which is intercalated with copper ions...
