Microcredit generally benefits borrowers, according to new research focused on Mexico’s biggest for-profit microlender — but it’s not lifting people out of poverty.
In a multi-year, randomized evaluation of microloans provided by Compartamos Banco, Yale University economist Dean Karlan, with collaborators Manuela Angelucci of the University of Michigan and Jonathan Zinman of Dartmouth College, show there are generally positive effects on average and find little evidence that some borrowers end up worse off while others end up better off. However, the canonical story that microcredit leads to higher enterprise income did not bear fruit. (more…)
The ancestor of all modern African monkeys was alive 3 million years earlier than previously thought and coexisted with members of a now-extinct branch of the monkey family tree, according to new evidence from anthropologists.
“We pushed back the origin of modern monkeys by a huge chunk of time,” said anthropologist Andrew Hill of Yale University, the senior researcher on the project. “This means there are all sorts of things we can think about. You can start to look at animal interactions that might have taken place.” (more…)

One of the world’s first working circular particle accelerators returns to Berkeley Lab—75 years later.
Seventy-five years after one of the world’s first working cyclotrons was handed to the London Science Museum, it has returned to its birthplace in the Berkeley hills, where the man who invented it, Ernest O. Lawrence, helped launch the field of modern particle physics as well as the national laboratory that would bear his name, Lawrence Berkeley National Laboratory.
On Jan. 9, 1932 the brass cyclotron—which measures 26 inches from end to end and whose accelerating chamber measures just 11 inches in diameter—was successfully used to boost protons to energies of 1.22 million electron volts. Its return to Berkeley Lab caps a decades-long saga in which various parties endeavored to secure the cyclotron’s return from London, but the persistence of Pamela Patterson, who chronicles Berkeley Lab’s history as managing editor of its website, finally paid off.

Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing.
Quantum computers would be exponentially faster than the most powerful computers of today. (more…)
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…)
