Spitzer and ALMA Reveal a Star’s Bubbly Birth

It’s a bouncing baby . . . star! Combined observations from NASA’s Spitzer Space Telescope and the newly completed Atacama Large Millimeter/submillimeter Array (ALMA) in Chile have revealed the throes of stellar birth as never before in the well-studied object known as HH 46/47.

Herbig-Haro (HH) objects form when jets shot out by newborn stars collide with surrounding material, producing small, bright, nebulous regions. To our eyes, the dynamics within many HH objects are obscured by enveloping gas and dust. But the infrared and submillimeter wavelengths of light seen by Spitzer and ALMA, respectively, pierce the dark cosmic cloud around HH 46/47 to let us in on the action. (more…)

Another Yale Nobel: Robert Shiller

Robert J. Shiller, the Sterling Professor of Economics at Yale University, has been awarded a Nobel Prize in Economic Sciences. He shares the award — formally, the 2013 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel — with Eugene F. Fama and Lars Peter Hansen from the University of Chicago. According to the Nobel committee, the three were honored “for their empirical analysis of asset prices.”

Shiller, whose name became a household word with the wide use of the Case-Shiller Home Price real estate Index, came to national prominence with the publication in 2000 of “Irrational Exuberance.” The book, which quickly became a bestseller, described speculative bubbles fueled by mass misinformation and herd instinct, and accurately predicted the dot.com implosion. As early as 2003, Shiller warned of the housing market collapse, and later wrote a precept for recovery, “Subprime Solution: How the Global Financial Crisis Happened and What to Do about It.” (more…)

History of fight for rights of LGBT parents to be preserved at Yale

The Yale University Library and the Family Equality Council are partnering to preserve the history of the lesbian, gay, bisexual, and transgender (LGBT) parent equality movement.

It was announced on Oct. 10 that Family Equality, which represents the 3 million LGBT parents in America and their 6 million children, will deed to Yale all historical materials related to the organization and its role in the LGBT family equality movement. The agreement ensures the preservation of more than 30 years of materials related to the founding, growth, and expansion of Family Equality, and documents the organization’s ongoing efforts to advance equality for families with LGBT parents.

Newly unearthed ruins challenge views of early Romans

ANN ARBOR — In a long-buried Italian city, archaeologists have found a massive monument that dates back 300 years before the Colosseum and 100 years before the invention of mortar, revealing that the Romans had grand architectural ambitions much earlier than previously thought.

The structure, unearthed at the site known as Gabii, just east of Rome, is built with giant stone blocks in a Lego-like fashion. It’s about half the size of a football field and dates back 350-250 years BCE. It’s possibly the earliest public building ever found, said Nicola Terrenato, a University of Michigan classics professor who leads the project—the largest American dig in Italy in the past 50 years.

The value of seeing a mind in meditation

Using neurofeedback techniques, Dr. Judson Brewer of Yale says he can teach people to “see” the subjective experience known to meditators as mindfulness. Brewer explains that too often we trip ourselves up when we get caught up in our own thinking. In the video and accompanying research papers, Brewer and colleagues describe how subjects can […]

From flounders to seahorses: Evolutionary success of spiny-rayed fishes detailed

Even as the dinosaurs were becoming extinct 66 million years ago, the ancient ancestor of spiny-rayed fishes flourished, eventually giving rise to tens of thousands of species that can now be found in home aquariums or on dinner plates. Using modern genetic tools and information from the fossil record, a team led by researchers at Yale University, University of Oxford, and University of California-Davis have constructed a detailed evolutionary history of the 18,000 species of spiny-rayed fishes existing today, a diverse group that includes basses, pufferfishes, and cichlids, and that comprises a large portion of the vertebrate tree of life.

The findings published the week of July 15 in the Proceedings of the National Academy of Sciences show surprisingly close evolutionary relationships between lineages of fish species such as tunas and seahorses, and suggest some fish lineages — like cichlids, the tiny gobies, and little-studied snailfishes — are experiencing high rates of new species origination.

How the turtle got its shell

The turtle has been in no rush to give up the secret of its shell — but after two centuries of close study, scientists are filling in the story of a structure unique in the history of life.

New research led by Tyler Lyson of Yale University and the Smithsonian Institution pushes back the origins of the turtle shell by about 40 million years, linking it to Eunotosaurus, a 260-million-year-old fossil reptile from South Africa. The work strengthens the fossil record and bolsters an existing theory about shell development while providing new details about its precise evolutionary pathway. (more…)
