Researchers at the UH Manoa School of Ocean and Earth Science and Technology (SOEST) made a discovery that challenges a major theory in the field of coral reef ecology.

The general assumption has been that the more flexible corals are, regarding which species of single-celled algae (Symbiodinium) they host in coral tissues, the greater ability corals will have to survive environmental stress. In their paper published August 29, 2012, however, scientists at the Hawaii Institute of Marine Biology (HIMB) at SOEST and colleagues documented that the more flexible corals are, the more sensitive to environment disturbances they are.

Supernovae of the Same Brightness, Cut From Vastly Different Cosmic Cloth

Berkeley Lab researchers make historic observation of rare Type 1a Supernova

Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively the same luminosity everywhere. Although astronomers have many theories about the kinds of star systems involved in these explosions (or progenitor systems), no one has ever directly observed one—until now.

In the August 24 issue of Science, the multi-institutional Palomar Transient Factory (PTF) team presents the first-ever direct observations of a Type 1a supernova progenitor system. Astronomers have collected evidence indicating that the progenitor system of a Type 1a supernova, called PTF 11kx, contains a red giant star. They also show that the system previously underwent at least one much smaller nova eruption before it ended its life in a destructive supernova. The system is located 600 million light years away in the constellation Lynx. (more…)

Astronomers Test Einstein in a New Regime Using Pair of Burnt-Out Stars

AUSTIN, Texas — A team of astronomers led by researchers from The University of Texas at Austin has confirmed the emission of gravitational waves from the second-strongest known source in our galaxy by studying the shrinking orbital period of a unique pair of burnt-out stars. Their observations tested Albert Einstein’s theory of general relativity in a new regime. The results will be published soon in The Astrophysical Journal Letters.

Last year, the same team discovered that the two white dwarf stars are so close together that they make a complete orbit in less than 13 minutes, and they should be gradually slipping closer. The system, called SDSS J065133.338+284423.37 (J0651 for short), contains two white dwarf stars, which are the remnant cores of stars like our sun. (more…)

Meet a Face Behind the MIRI

This summer welcomed the delivery of the James Webb Space Telescope’s first flight instrument, the Mid-Infrared Instrument (MIRI). The instrument will peer out into the farthest depths of the cosmos and capture light showcasing star and galaxy formation.

MIRI’s design, assembly and journey were made possible because of a collaboration between a European consortium of institutes that developed the instrument in a partnership with NASA’s Jet Propulsion Laboratory, Pasadena, Calif., working with the European Space Agency, University of Arizona and NASA.

Astronomers Using the Hubble Space Telescope Report the Earliest Spiral Galaxy Ever Seen

Astronomers have witnessed for the first time a spiral galaxy in the early universe, billions of years before many other spiral galaxies formed. In findings reported July 19 in the journal Nature, the astronomers said they discovered it while using the Hubble Space Telescope to take pictures of about 300 very distant galaxies in the early universe and to study their properties. This distant spiral galaxy is being observed as it existed roughly three billion years after the Big Bang, and light from this part of the universe has been traveling to Earth for about 10.7 billion years.

“As you go back in time to the early universe, galaxies look really strange, clumpy and irregular, not symmetric,” said Alice Shapley, a UCLA associate professor of physics and astronomy, and co-author of the study. “The vast majority of old galaxies look like train wrecks. Our first thought was, why is this one so different, and so beautiful?” (more…)

The ‘New’ Bing: Transforming Search from Finding to Doing

Bing’s new user experience surfaces the best from the Web, friends and experts to help people do more.

REDMOND, Wash. – May 10, 2012 – Microsoft today unveiled a major update to its Bing search engine that fundamentally transforms the way users search the Web. The update, the most significant since Microsoft launched Bing three years ago, is designed to help users act quickly by taking advantage of the Web’s evolving fabric.

With the new version of Bing, rolling out over the coming weeks and broadly available in the U.S. in early June, people can easily get advice and recommendations from friends and experts with the new social sidebar. They can also view useful, action-oriented information via the new snapshot feature. And they can find what they’re looking for faster, with more relevant results and a refreshed user interface. All of this is presented in a new, three-column design that focuses on helping users take the leap from finding information to making quick, informed decisions. (more…)

Black Hole Caught Red-Handed in a Stellar Homicide

PASADENA, Calif. – Astronomers have gathered the most direct evidence yet of a supermassive black hole shredding a star that wandered too close. NASA’s Galaxy Evolution Explorer, a space-based observatory, and the Pan-STARRS1 telescope on the summit of Haleakala in Hawaii were among the first to help identify the stellar remains.

Supermassive black holes, weighing millions to billions times more than the sun, lurk in the centers of most galaxies. These hefty monsters lie quietly until an unsuspecting victim, such as a star, wanders close enough to get ripped apart by their powerful gravitational clutches. (more…)

Safe Sleep Environments Key to Preventing Many Infant Deaths, MU Researcher Says

COLUMBIA, Mo. – Since 1992, the government’s Back-to-Sleep Campaign has encouraged parents to place infants on their backs to sleep. Still, more than 4,500 infants die unexpectedly during sleep each year in the United States. Now, a University of Missouri injury prevention researcher says that safe, separate sleep environments for infants are critical to preventing sudden unexpected infant deaths (SUIDs).

“Many of these SUIDs are due to unsafe sleep environments, and these deaths are totally preventable,” said Patricia Schnitzer, an associate professor in the MU Sinclair School of Nursing. “The safest place for infants to sleep is on their backs in their own cribs without soft bedding.” (more…)
