Humans can’t survive more than a few days without water, but some plants, in particular mosses, can survive drought for decades and suddenly revive with the first rain. KQED’s “Deep Look” team visited UC Berkeley’s University and Jepson Herbaria to learn about these so-called “resurrection plants.”
Philomathia Innovation Seed Fund recipients Catherine Wolfram and Meredith Fowlie carried out a rigorous study that found surprisingly low savings relative to costs in part of a nationwide effort to improve home energy-efficiency.
The debate over the legalization of marijuana has focused primarily on questions of law, policy and health. But a new paper co-authored by UC Berkeley researchers shines a spotlight on the environmental damage caused by illegal marijuana plantations in sensitive watersheds.
The problem is simple to understand. Molecules of carbon and other greenhouse gases absorb heat. The more greenhouse gases emitted into the atmosphere, the warmer the atmosphere becomes, exacerbating global climate change. Solving the problem is not so simple, especially with regards to aviation – the source of two-percent of the annual greenhouse gas emissions from human activity.
Philomathia Innovation Seed Fund recipient Eric Brewer works with tech savvy students in electrical engineering and computer science, urban planning, business, and economics to help developing countries gain access to affordable energy.
Cold-blooded and other animals that are unable to regulate their internal temperature may have a hard time tolerating global warming, according to an analysis by biologists from the University of California, Berkeley, and San Francisco State University.
Steadily and alarmingly, humans have been depleting Earth’s soil resources faster than the nutrients can be replenished. If this trajectory does not change, soil erosion, combined with the effects of climate change, will present a huge risk to global food security over the next century.
A potentially game-changing breakthrough in artificial photosynthesis has been achieved with the development of a system that can capture carbon dioxide emissions before they are vented into the atmosphere and then, powered by solar energy, convert that carbon dioxide into valuable chemical products.
A new study quantifying the amount of carbon stored and released through California forests and wildlands finds that wildfires and deforestation are contributing more than expected to the state’s greenhouse gas emissions.
In the first study of its kind, scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) quantitatively show that electric vehicles (EVs) will meet the daily travel needs of drivers longer than commonly assumed.
Capturing carbon from power plants is likely in the future to avoid the worst effects of climate change, but current technologies are very expensive. A new material, a diamine-appended metal-organic framework, captures and releases CO2 with much reduced energy costs compared to today’s technologies, potentially lowering the cost of capturing this greenhouse gas.
Biomass conversion to electricity combined with new technologies for capturing and storing carbon, which should become viable within 35 years, could result in a carbon-negative power grid in the Western United States by 2050.
Historical California vegetation data that more than once dodged the dumpster have now proved their true value, documenting that a changing forest structure seen in the Sierra Nevada has actually happened statewide over the past 90 years.
Organic semiconductors are prized for light emitting diodes (LEDs), field effect transistors (FETs) and photovoltaic cells. As they can be printed from solution, they provide a highly scalable, cost-effective alternative to silicon-based devices. Uneven performances, however, have been a persistent problem. That’s now changed.
An international collaboration including Neil Davies, Director of UC Berkeley's Gump Station, is preparing to create a digital representation of of the Pacific island of Moorea to create a virtual lab to test and hypothesize the impact of human activities.
Researchers at Lawrence Berkeley National Laboratory and the University of California, Berkeley, have developed a new precision approach for synthesizing graphene nanoribbons from pre-designed molecular building blocks. Using this process the researchers have built nanoribbons that have enhanced properties—such as position-dependent, tunable bandgaps—that are potentially very useful for next-generation electronic circuitry.
A new study led by engineers at UC Berkeley and CITRIS describes the first direct observation of a long-hypothesized but elusive phenomenon called “negative capacitance.” The work describes a unique reaction of electrical charge to applied voltage in a ferroelectric material that could open the door to a radical reduction in the power consumed by transistors and the devices containing them.
Today’s climate models predict a 50 percent increase in lightning strikes across the US during this century as a result of warming temperatures associated with climate change. UC Berkeley climate scientists look at predictions of precipitation and cloud buoyancy in 11 different climate models and conclude that their combined effect will generate more frequent electrical discharges to the ground.
