More than a billion people worldwide lack access to electricity, and even a $15 solar lamp is beyond the financial reach for many of them. Yet businesses have found a way to reach this very-low-income market through rent-to-own programs that combine incremental payments with technology to monitor and lock out non-paying customers.
Urban traffic roughly follows a periodic pattern associated with the typical “9 to 5” work schedule. However, when an accident happens, traffic patterns are disrupted. Designing accurate traffic flow models, for use during accidents, is a major challenge for traffic engineers, who must adapt to unforeseen traffic scenarios in real time.
For the fifth straight year, UC Berkeley tops the list of public universities in global rankings by U.S. News & World Report. And, for the third year in a row, the campus ranks fourth-best overall among publics and privates. U.S. 新闻’ 2020 rankings evaluated 1,500 universities across 81 countries based on published academic research and reputation, among other criteria.
From habitat loss to climate change, amphibians around the world face immense threats to their survival. One emerging and sinister threat is the chytrid fungus, a mysterious pathogen that kills amphibians by disrupting the delicate moisture balance maintained by their skin, and that is decimating frog populations around the world.
Nine UC Berkeley faculty have been elected to the American Academy of Arts and Sciences, a prestigious nonpartisan research center that convenes scholars and leaders in academic, business and government sectors, drawing expertise across disciplines, to address the most complex challenges of our time. Here are this year’s honorees:
In a new study, researchers at UC Berkeley and Berkeley Lab describe how the architecture of the long-horned passalid beetle's gut — and the beneficial microbes that inhabit it — help the beetle carry out an amazing transformation. This knowledge could help scientists engineer more efficient systems for producing bioproducts in the lab.
UC Berkeley integrative biology Ph.D. student Alexander Stubbs and colleague determined that a mysterious noise reported by U.S. diplomats stationed in Cuba plagued by resulting hearing loss and other medical symptoms was not from sonic attacks as feared, but was produced by the Indies short-tailed cricket (Anurogryllus celerinictus).
Women and underrepresented minorities in STEM fields are more likely to advance professionally, publish more research and secure postdoctoral and faculty positions if their institutional culture is welcoming and sets clear expectations, according to a study of hundreds of Ph.D. students at four top-tier California research universities.
