Astronomy & Space news

	Distant quasar spectrum reveals no sign of changes in mass ratio of proton and electron over 12 billion years A team of space researchers working with data from the VLT in Chile has found via measuring the spectrum of a distant quasar by analyzing absorption lines in a galaxy in front of it, that there was no measurable change in the mass ratio of protons and electrons over a span of 12 billion years. In their paper published in the journal Physical Review Letters, the team, made up of two members from VU University in the Netherlands, and two members from Swinburne University of Technology in Australia, describe their findings and what it might mean for helping to explain dark energy.
	Earth's other 'moon' and its crazy orbit could reveal mysteries of the solar system We all know and love the moon. We're so assured that we only have one that we don't even give it a specific name. It is the brightest object in the night sky, and amateur astronomers take great delight in mapping its craters and seas. To date, it is the only other heavenly body with human footprints.
	How to see quasars with backyard telescopes "How far can you see with that thing?" It's a common question overhead at many public star parties in reference to telescopes.
	A new sungrazing comet may brighten in the evening sky A newly-discovered comet may soon become bright enough to see from a sky near you. Originally dubbed SOHO-2875, it was spotted in photos taken by the Solar and Heliospheric Observatory (SOHO) earlier this week. Astronomer Karl Battams, who maintains the Sungrazer Project website, originally thought this little comet would dissipate after its close brush with the Sun. To his surprise, it outperformed expectations and may survive long enough to see in the evening sky.
	Monster black hole discovered at cosmic dawn Scientists have discovered the brightest quasar in the early universe, powered by the most massive black hole yet known at that time. The international team led by astronomers from Peking University in China and from the University of Arizona announce their findings in the scientific journal Nature on Feb. 26.

Medicine & Health news

	Widely used food additive promotes colitis, obesity and metabolic syndrome, research shows Emulsifiers, which are added to most processed foods to aid texture and extend shelf life, can alter the gut microbiota composition and localization to induce intestinal inflammation that promotes the development of inflammatory bowel disease and metabolic syndrome, new research shows.
	Study finds that animals and humans have similar lash length It started with a trip to the basement of the American Museum of Natural History in New York to inspect preserved animal hides. Later, Georgia Institute of Technology researchers built a wind tunnel about 2 feet tall, complete with a makeshift eye. By putting both steps together, the team discovered that 22 species of mammals - from humans, to hedgehogs, to giraffes ¬- are the same: their eyelash length is one-third the width of their eye. Anything shorter or longer, including the fake eyelashes that are popular in Hollywood and make-up aisles, increases airflow around the eye and leads to more dust hitting the surface.
