| California's 2020 wildfire season Posted: 04 May 2022 11:45 AM PDT A new study summarizing the 2020 California wildfire year said just over 9,900 wildfires burned 4.3 million acres in 2020. That's twice the previous record but only average compared to burn rates before Euro-American settlement. Fire severity is the far greater concern. |

| Squid and octopus genome studies reveal how cephalopods' unique traits evolved Posted: 04 May 2022 05:23 AM PDT Squid, octopus, and cuttlefish -- even to scientists who study them -- are wonderfully weird creatures. Known as the soft-bodied or coleoid cephalopods, they have the largest nervous system of any invertebrate, complex behaviors such as instantaneous camouflage, arms studded with dexterous suckers, and other evolutionarily unique traits. Now, scientists have dug into the cephalopod genome to understand how these unusual animals came to be. Along the way, they discovered cephalopod genomes are as weird as the animals are. Scientists from the Marine Biological Laboratory (MBL) in Woods Hole, the University of Vienna, the University of Chicago, the Okinawa Institute of Science and Technology and the University of California, Berkeley, reported their findings in two new studies in Nature Communications. |
