    “This research holds promise for treating serious neurodegenerative diseases that impact millions of people each year. Our researchers at the University of Maryland School of Medicine have discovered what could be a critical and non-invasive way to use stem cells as a therapy for these diseases,” said UMSOM Dean, E. Albert Reece, MD, PhD, MBA, Executive Vice President for Medical Affairs, UM Baltimore, and the John Z. and Akiko K. Bowers Distinguished Professor.

    Researchers discover certain skin-related stem cells could help in treating neurogenerative diseases. Neurodegenerative diseases like multiple sclerosis (MS) affect millions of people worldwide and occur when parts of the nervous system lose function over time...

    Experimental device generates Electricity from the Coldness of the Universe

    May 7, 2019, Categories  Technology/Electronics, Physics

    A drawback of solar panels is that they require sunlight to generate electricity. Some have observed that for a device on Earth facing space, the chilling outflow of energy from the device can be harvested using the same kind of optoelectronic physics we have used to harness solar energy. New work, in Applied Physics Letters, looks to provide a potential path to generating electricity like solar cells but that can power electronics at night. This is a schematic of the experimental infrared photodiode that has generated electricity directly from the coldness of space.

    Telescopes in Space for even Sharper Images of Black Holes

    May 7, 2019, Categories  Astronomy/Space

    In space, the EHI has a resolution more than five times that of the EHT on Earth, and images can be reconstructed with higher fidelity.

    Astronomers propose placing two or three satellites in circular orbit around the Earth to observe black holes. Astronomers have just managed to take the first image of a black hole, and now the next challenge facing them is how to take even sharper images, so that Einstein’s Theory of General Relativity can be tested...

    Blue Supergiant Stars Open Doors to Concert in Space

    May 7, 2019, Categories  Astronomy/Space

    A snapshot from a hydrodynamical simulation of the interior of a star three times as heavy as our Sun, which shows waves generated by turbulent core convection and propagating throughout the star’s interior. Darker and lighter colours represent fluctuations due to waves.

    Almost all blue supergiants shimmer in brightness because of waves on their surface. Blue supergiants are rock-and-roll: they live fast and die young. This makes them rare and difficult to study. Before space telescopes were invented, few blue supergiants had been observed, so our knowledge of these stars was limited...
