Crews were battling wildfires in the San Francisco Bay Area and thousands of people were under orders to evacuate as dozens of wildfires blazed across the state amid a blistering heat wave now in its second week.

In an important step toward practical implementation of secure quantum-based communication, researchers have demonstrated secure measurement-device-independent quantum key distribution (MDI-QKD) transmission over a record-breaking 170 kilometers.
An open-source educational biotechnology called the "Genetic Code Kit" has been developed by California Polytechnic State University researchers to allow students to interact with the molecular process inside cells in new ways. Researchers show that adapting state-of-the-art biotechnology for the classroom could transform how biology and biochemistry are taught to high school and undergraduate...
Astronomers have used NASA's Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Earth.
The rapid pace that invasive shrubs infiltrate forests in the northeastern United States makes scientists suspect they have a consistent advantage over native shrubs, and the first region-wide study of leaf timing, conducted by Penn State researchers, supports those suspicions.
Science is suffering from a replication crisis. Too many landmark studies can't be repeated in independent labs, a process crucial to separating flukes and errors from solid results. The consequences are hard to overstate: Public policy, medical treatments and the way we see the world may have been built on the shakiest of foundations.
In a new paper this week, geographer Forrest Bowlick at the University of Massachusetts Amherst and colleagues at Texas A&M offer first-hand accounts of what is required for GIS instructors and IT administrators to set up virtual computing specifically for providing state-of-the-art geographic information systems (GIS) instruction.
A robust, low-cost imaging platform utilizing lab-on-a-chip technology created by University of California, Irvine scientists may be available for rapid coronavirus diagnostic and antibody testing throughout the nation by the end of the year.
Just north of the Golden Gate Bridge, yet a world away from San Francisco, in an unincorporated and oft-overlooked area known as Marin City, sea level rise is rarely the first worry that comes to mind.
NASA-NOAA's Suomi NPP satellite kept an eye on Hurricane Genevieve overnight and provided infrared imagery to forecasters who were monitoring the storm's strength, structure and size. Because Genevieve is close to the coast of western Mexico, warnings and watches were still in effect.
NASA-NOAA's Suomi NPP satellite provided forecasters with a visible image of the landfall of Tropical Storm Higos on Aug. 18.
Powerful Hurricane Genevieve began flinging rain at Mexico's Baja California Peninsula on Wednesday and it threatened to bring hurricane-force winds to the tourist region even if its center wasn't likely to hit land.
California staved off another round of rolling blackouts as a searing heat wave strained its electrical grid, but authorities warned of a continuing threat Wednesday.
Newly published research in Science Advances by University of Chicago researcher Luis Bettencourt proposes a new perspective and models on several known paradoxes of cities. Namely, if cities are engines of economic growth, why do poverty and inequality persist? If cities thrive on faster activity and more diversity, why are so many things so hard to change? And if growth and innovation are so...
The evolution of limbs with functional digits from fish fins happened approximately 400 million years ago in the Devonian. This morphological transition allowed vertebrates to leave the water to conquer land and gave rise to all four-legged animals or tetrapods—the evolutionary lineage that includes all amphibians, reptiles, birds and mammals (including humans). Since the nineteenth century...
Bacteria that can help defuse highly toxic dioxin in sediments in the Passaic River—a Superfund hazardous waste site—could eventually aid cleanup efforts at other dioxin-contaminated sites around the world, according to Rutgers scientists.
NASA's Mars rovers have been one of the great scientific and space successes of the past two decades.
Special metal oxides could one day replace semiconductor materials that are commonly used today in processors. Now, for the first time, an international team of researchers from Martin Luther University Halle-Wittenberg (MLU), the University of Kaiserslautern and the University of Fribourg in Switzerland was able to observe how electronic charge excitation changes electron spin in metal oxides in...
Traditional ways of producing entanglements, necessary for the development of any 'quantum internet' linking quantum computers, are not very well suited for fiber optic telecoms networks used by today's non-quantum internet. However, researchers have come up with a new way to produce such particles that is much more compatible.
Researchers, who remotely videotaped a generation of wild chimpanzees learning to use tools, gain insights into how technology came to define human culture.
Scientists from the ESRF, together with teams from CEA and CNRS/Sorbonne Université, have found the proof for a liquid-to-liquid transition in sulfur and of a new kind of critical point ending this transition. Their work is published in Nature.
Marine pollutants are taken up by corals directly from seawater as well as through accumulation in their food, shows research from KAUST that uses a state-of-the-art spectroscopy technique known as cavity ring-down spectroscopy. This is the first time the approach has been used to measure pollutant accumulation.
Dry soils in Germany, heat records in the Arctic and thawing permafrost soils in Siberia. The consequences of climate change are visible across the globe. To reduce the concentration of carbon dioxide (CO2) in the atmosphere, numerous research groups are investigating how CO2 can be used as a raw material for the production of chemicals.
PIM kinases are enzymes that promote metastatic growth and spread of cancer cells. Researchers from the University of Turku, Finland, have obtained new information on how PIM kinases enhance cancer cell motility by regulating the formation of actin fibers in the cytoskeleton. The published results support the development of PIM-targeted therapies to prevent metastasis formation in cancer patients.
Researchers at the University of Bern have developed the highly sensitive ORIGIN instrument, which can provide proof of the smallest amounts of traces of life, for future space missions. Space agencies such as NASA have already expressed interest in testing ORIGIN for future missions. The instrument may be used on missions to the ice moons of Europa (Jupiter) and Enceladus (Saturn), for example.
