Campus graduate student Ian Bolliger is designing small solar-powered houses of less than 400 square feet with approximately 20 other UC Berkeley students. He and two other UC Berkeley graduate students presented their design at the United Nations’ annual climate conference in Paris, which began Nov. 30 and will run until Friday.

In a study published Monday, researchers, including one from UC Berkeley, discovered that the extinction of large land mammals near the end of the Ice Age had permanent effects on the Earth’s ecosystem.

After years of warnings from ecologists about the dangers of biodiversity loss, a new study has quantified an ongoing mass extinction event — the sixth in our planet’s history — and suggests humans are largely to blame.
