MUSE spectrograph reveals uncovered vast cosmic reservoirs of atomic hydrogen. An unexpected abundance of Lyman-alpha emission in the Hubble Ultra Deep Field (HUDF) region was discovered by an international team of astronomers using the MUSE instrument on ESO’s Very Large Telescope (VLT). The discovered emission covers nearly the entire field of view – leading the team to extrapolate that almost all of the sky is invisibly glowing with Lyman-alpha emission from the early Universe.

Astronomers have long been accustomed to the sky looking wildly different at different wavelengths, but the extent of the observed Lyman-alpha emission was still surprising...

Natural product found to reduce the level of damaged cells in the body, caused by aging. Previous research published earlier this year in Nature Medicine involving University of Minnesota Medical School faculty Paul D. Robbins and Laura J. Niedernhofer and Mayo Clinic investigators James L. Kirkland and Tamara Tchkonia, showed it was possible to reduce the burden of damaged cells, ie senescent cells, and extend lifespan and improve health, even when treatment was initiated late in life...

A new method enables non-invasive monitoring of oxygen metabolism in cells that are 3D-bioprinted into complex living structures. This has great implications for studies of cell growth and interactions e.g. under tissue-like conditions, as well as for the design of 3D printed constructs facilitating higher productivity of microalgae in biofilms or better oxygen supply for stem cells used in bone and tissue reconstruction efforts.

An international team of researchers led by Professor Michael Kühl at the Department of Biology, University of Copenhagen has just published a breakthrough in 3D bioprinting...

An artist’s conception of a distant Solar System Planet X, which could be shaping the orbits of smaller extremely distant outer Solar System objects like 2015 TG387 discovered by a team of Carnegie’s Scott Sheppard, Northern Arizona University’s Chad Trujillo, and the University of Hawaii’s David Tholen.

The newly found object, called 2015 TG387, will be announced Tuesday by the International Astronomical Union’s Minor Planet Center. Astronomers have discovered a new extremely distant object far beyond Pluto with an orbit that supports the presence of an even-farther-out, Super-Earth or larger Planet X.

Carnegie’s Scott Sheppard and his colleagues – Northern Arizona University’s...
