Structural biologists have made important progress towards better understanding the functioning of the circadian clock. The circadian or inner clock coordinates the sleep-wake rhythm and many other body processes that regulate, for example, metabolism, blood pressure, and the immune system.

A research team led by Professor Eva Wolf, recently appointed Professor of Structural Biology at the Institute of General Botany of Johannes Gutenberg University Mainz (JGU) and Adjunct Director at the Institute of Molecular Bi Continue reading

The tangled highway of blood vessels that twists and turns inside our bodies, delivering essential nutrients and disposing of hazardous waste to keep our organs working properly has been a conundrum for scientists trying to make artificial vessels from scratch. Now a team from Brigham and Women’s Hospital (BWH) has made headway in fabricating blood vessels using a three-dimensional (3D) bioprinting technique.

“Engineers have made incredible strides in making complex artificial tissues such as those of the heart, liver and lungs,&#8 Continue reading

A volcano errupted in Indonesia Friday, forcing evacuation of farmers from the areas on the slope of the volcano, official said.

A powerful burst of hot ashes erupted from the rumbling Mount Sangiang in West Nusatenggara province, Xinhua reported.

The volcano, located in a small island of Bima district, spewed ashes into the sky at 3.55 p.m., Muhammad Hendrasto, head of the National Volcanology Agency, said.

“Scores of farmers cultivating the land in the island, seven km from the crater, have been told to leave the Continue reading

NASA’s Chandra X-ray Observatory has shed new light on the mystery of why giant elliptical galaxies have few, if any, young stars.

This new evidence highlights the important role that supermassive black holes play in the evolution of their host galaxies.

Because star-forming activity in many giant elliptical galaxies has shut down to very low levels, these galaxies mostly house long-lived stars with low masses and red optical colors. Astronomers have therefore called these galaxies “red and dead.”
