The number of known places in our galaxy theoretically hospitable to life may be significantly greater than previously thought, according to new research.
Researchers with Planet Hunters are reporting the discovery of a Jupiter-sized planet in the so-called “habitable zone” of a star similar to Earth’s sun, as well as the identification of 15 new candidate planets also orbiting within their star’s habitable zone. (more…)
The gut bacteria of honey bees have acquired several genes that confer resistance to tetracycline, a direct result of more than five decades of use of antibiotics by American beekeepers and a potential health hazard for bee colonies, a new study by Yale University researchers show.
The genetic analysis of the gut bacteria, which are believed to help in bees’ digestion and ability to ward off parasites, suggests changing antibiotic use by beekeepers might be one factor in the mysterious colony collapse disorder afflicting bee populations. (more…)
No longer primarily paper documents, donations to the Yale University Library now also come in digital forms and formats — including floppy disks, CDs, DVDs, and flash drives. Archivists are faced with a new and challenging dilemma: how to preserve “born-digital” collections in a form that can be read by available technology and also saved in a way that will be accessible in the future.
At Yale Library’s Manuscripts & Archives department, Mark Matienzo, Digital Archivist, is helping to develop strategies to reclaim and organize information that was created within the past 20 years — on media that may be already becoming obsolete. (more…)
The most-studied mass extinction in Earth history happened 65 million years ago and is widely thought to have wiped out the dinosaurs. New University of Washington research indicates that a separate extinction came shortly before that, triggered by volcanic eruptions that warmed the planet and killed life on the ocean floor.
The well-known second event is believed to have been triggered by an asteroid at least 6 miles in diameter slamming into Mexico’s Yucatán Peninsula. But new evidence shows that by the time of the asteroid impact, life on the seafloor – mostly species of clams and snails – was already perishing because of the effects of huge volcanic eruptions on the Deccan Plateau in what is now India.

Michael Dula recently began his appointment as chief technology officer for the Yale University Library, which is one of the largest university libraries in North America. In this newly created role, he will develop a technology strategy for the University’s 18 different libraries, which house over 12.5 million volumes.
Prior to coming to Yale, Dula worked at Pepperdine University, where he began as a consultant. In 2006, he accepted a full-time position at Pepperdine as director of digital initiatives for the university’s libraries. In addition to managing central library technology systems, he was actively engaged in implementing new tools for research and learning, including digital content collections, scholarly publishing, podcasting, and social computing models.

The most common lineages of fish found today in oceans, lakes, and rivers evolved about the same time as mammals and birds, a new Yale University-led study shows.
The comparative genetic analysis of more than 200 fish species, reported the week of Aug. 6 in the Proceedings of the National Academy of Sciences, gave an earlier than expected evolutionary birthday to well-known teleost — or ray-finned — fish such as salmon, bass, or tuna.
The analysis also shows that the very earliest lineages of living teleost fish were eels and bonefishes, not tropical freshwater bonytongue fish as some scientists had proposed. (more…)
Yale University scientists have developed a new mechanism for attacking cancerous tumors that intensifies the body’s immune response while simultaneously weakening the tumor’s ability to resist it.
“We believe this is a paradigm-changing immunotherapeutic method for cancer therapy,” said Tarek M. Fahmy, a bioengineer at Yale and the project’s principal investigator. “In essence, it’s a one-two punch strategy that seems to work well for melanoma and may work even better with other cancers.” (more…)
Women in rural Bangladesh prefer inexpensive, traditional stoves for cooking over modern ones — despite significant health risks, according to a Yale study in the Proceedings of the National Academy of Sciences.
A large majority of respondents (94%) believed that indoor smoke from the traditional stoves is harmful. Still, Bangladeshi women opted for traditional cookstove technology so they could afford basic needs.
“Non-traditional cookstoves might be more successful if they were designed with features valued more highly by users, such as reducing operating costs even if they might not reduce environmental impact,” said Mushfiq Mobarak, a co-author and associate professor of economics at the Yale School of Management.
