The second-most distant quasar ever discovered now has a Hawaiian name. Astronomers have discovered the second-most distant quasar ever found using three Maunakea Observatories in Hawai’i: W. M. Keck Observatory, the international Gemini Observatory, a Program of NSF’s NOIRLab, and the University of Hawai’i-owned United Kingdom Infrared Telescope (UKIRT). It is the first quasar to receive an indigenous Hawaiian name, Poniua’ena, which means “unseen spinning source of creation, surrounded with brilliance” in the Hawaiian language.

Poniua’ena is only the second quasar yet detected at a distance calculated at a cosmological redshift greater than 7...

Receptor makes Mice Strong and Slim

Molecule that regulates two side effects of aging identified. Increasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers at the University of Bonn have discovered a receptor in mice that regulates both effects. Experiments with human cell cultures suggest that the corresponding signaling pathways might also exist in humans. The study, which also involved researchers from Spain, Finland, Belgium, Denmark and the USA, has now been published in the journal Cell Metabolism.

The surfaces of some cells are virtually teeming with A2B receptors, for example in the so-called brown adipose tissue. Brown adipose tissue, unlike its white-colored counterpart, is not used to store fat. Instead, it burns fat and thereby generates heat.

“In our publication we to...

Researchers Print, Tune Graphene Sensors to Monitor Food Freshness, Safety

Researchers are using aerosol-jet-printing technology to create these graphene biosensors that can detect histamine, an allergen and indicator of spoiled fish and meat. Image courtesy of Jonathan Claussen.

Researchers are using high-resolution printing technology and the unique properties of graphene to make low-cost biosensors to monitor food safety and livestock health.

It turned out the sensors — printed with high-resolution aerosol jet printers on a flexible polymer film and tuned to test for histamine, an allergen and indicator of spoiled fish and meat — can detect histamine down to 3.41 parts per million.

The U.S...

‘Mystery Object’ in space may be Smallest Black Hole

An artistic rendering shows a mysterious object roughly 800 million light-years from Earth detected using gravitational wave sensors, which is either one of the smallest black holes or one of the largest neutron stars so far discovered. The Advanced Virgo detector at the European Gravitational Observatory (EGO) in Italy and two wave observatories in the US discovered the object last year and calculated it to weigh around 2.6 times our own Sun. /AFP
