About 10,000 light years away from Earth, a black hole is engaged in a stellar feast, devouring the gases of a nearby star.
A stellar meal provides tantalizing new evidence about black hole evolution.

Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism.
The findings could bring about a better understanding of many cancers’ metabolic needs and lead to the development of more effective therapies for squamous cell skin cancer and other forms of epithelial cancer.
The research, led by senior authors Heather Christofk and Bill Lowry, was published in the journal Nature Communications.

CAPE CANAVERAL, Fla. (AP) — An asteroid-circling spacecraft has captured a cool snapshot of home.
NASA’s Osiris-Rex spacecraft took the picture days before going into orbit around asteroid Bennu on New Year’s Eve.
The tiny asteroid — barely one-third of a mile (500 meters) across — appears as a big bright blob in the long-exposure photo released last week. Seventy million miles (110 million kilometers) away, Earth appears as a white dot, with the moon an even smaller dot but still clearly visible.
A total of 73 previously unrecorded varieties of apples and pears believed to be unique to Wales have been discovered by researchers.
About 200 trees were DNA-tested in the two-year project to find, catalogue and preserve new varieties.
Some have been propagated and are now being grown in 13 community orchards around Wales.
The first direct evidence of white dwarf stars solidifying into crystals has been discovered by astronomers at the University of Warwick, and our skies are filled with them.
Observations have revealed that dead remnants of stars like our Sun, called white dwarfs, have a core of solid oxygen and carbon due to a phase transition during their lifecycle similar to water turning into ice but at much higher temperatures. This could make them potentially billions of years older than previously thought.
The discovery, led by Dr. Pier-Emmanuel Tremblay from the University of Warwick’s Department of Physics, has been published in Nature and is largely based on observations taken with the European Space Agency’s Gaia satellite.
SAN DIEGO (Reuters) — Boeing Co unveiled a speedier and higher-flying version of a concept plane on Tuesday aimed at sharply reducing fuel use thanks to its elongated ultra-light wings.
The so-called Transonic Truss-Braced Wing aircraft boasts a 170-foot (52 meter) wingspan that sits atop the fuselage and is braced from underneath by a truss in a design reminiscent of biplanes from the early years of aviation.
The world’s largest planemaker and U.S. space agency NASA have been studying the concept plane for nearly a decade as part of the Subsonic Ultra Green Aircraft Research program. Boeing unveiled a reconfigured model or prototype and artist’s rendering at an aerospace conference in San Diego.
