In 2014, researchers at the California Academy of Sciences added a whopping 221 new plant and animal species to our family tree, enriching our understanding of Earth's complex web of life and strengthening our ability to make informed conservation decisions. The new species include 110 ants, 16 beetles, three spiders, 28 fishes, 24 sea slugs, two marine worms, 9 barnacles, two octocorals, 25 plants, one waterbear, and one tiny mammal. More than a dozen Academy scientists--along with several dozen international collaborators--described the discoveries.
Methane is leaking from permafrost offshore Siberia
Published Dec 22, 2014 - 8:30:11 AM

NOAA: Arctic is warming at twice the rate of anywhere else on Earth
Published Dec 22, 2014 - 8:26:37 AM
A new NOAA-led report shows that Arctic air temperatures continue to rise at more than twice the rate of global air temperatures, a phenomenon known as Arctic amplification. Increasing air and sea surface temperatures, declining reflectivity at the surface of the Greenland ice sheet, shrinking spring snow cover on land and summer ice on the ocean, and declining populations and health of some polar bear populations are among the observations released today in the Arctic Report Card 2014.
Crows Are Smarter Than You Think
Published Dec 19, 2014 - 9:50:12 AM
Crows have long been heralded for their high intelligence – they can remember faces, use tools and communicate in sophisticated ways.
But a newly published study finds crows also have the brain power to solve higher-order, relational-matching tasks, and they can do so spontaneously. That means crows join humans, apes and monkeys in exhibiting advanced relational thinking, according to the research.
New, tighter timeline confirms ancient volcanism aligned with dinosaurs' extinction
Published Dec 19, 2014 - 9:47:30 AM
A definitive geological timeline shows that a series of massive volcanic explosions 66 million years ago spewed enormous amounts of climate-altering gases into the atmosphere immediately before and during the extinction event that claimed Earth's non-avian dinosaurs, according to new research from Princeton University.
Fine particulate air pollution linked with increased autism risk
Published Dec 18, 2014 - 9:05:47 AM
Women exposed to high levels of fine particulate matter specifically during pregnancy--particularly during the third trimester--may face up to twice the risk of having a child with autism than mothers living in areas with low particulate matter, according to a new study from Harvard School of Public Health (HSPH). The greater the exposure, the greater the risk, researchers found. It was the first U.S.-wide study exploring the link between airborne particulate matter and autism.
Report: Clearing Tropical Rainforests Distorts Earth’s Wind and Water Systems, Packs Climate Wallop Beyond Carbon
Published Dec 18, 2014 - 8:41:49 AM
A new study released today presents powerful evidence that clearing trees not only spews carbon into the atmosphere, but also triggers major shifts in rainfall and increased temperatures worldwide that are just as potent as those caused by current carbon pollution. Further, the study finds that future agricultural productivity across the globe is at risk from deforestation-induced warming and altered rainfall patterns.

How do fireflies produce those mesmerizing light flashes?
Published Dec 17, 2014 - 9:08:39 AM
Fireflies used rapid light flashes to communicate. This "bioluminescence" is an intriguing phenomenon that has many potential applications, from drug testing and monitoring water contamination, and even lighting up streets using glow-in-dark trees and plants. Fireflies emit light when a compound called luciferin breaks down. We know that this reaction needs oxygen, but what we don't know is how fireflies actually supply oxygen to their light-emitting cells. Using state-of-the-art imaging techniques, scientists from Switzerland and Taiwan have determined how fireflies control oxygen distribution to light up their cells. The work is published in Physical Review Letters.
Highly Pathogenic H5 Avian Influenza Confirmed in Wild Birds in Washington State
Published Dec 17, 2014 - 7:50:04 AM
The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of highly pathogenic (HPAI) H5 avian influenza in wild birds in Whatcom County, Washington. Two separate virus strains were identified: HPAI H5N2 in northern pintail ducks and HPAI H5N8 in captive Gyrfalcons that were fed hunter-killed wild birds. Neither virus has been found in commercial poultry anywhere in the United States and no human cases with these viruses have been detected in the United States, Canada or internationally. There is no immediate public health concern with either of these avian influenza viruses.
Study Hints That Ancient Earth Made Its Own Water-Geologically
Published Dec 17, 2014 - 7:08:56 AM
A new study is helping to answer a longstanding question that has recently moved to the forefront of earth science: Did our planet make its own water through geologic processes, or did water come to us via icy comets from the far reaches of the solar system?

NASA Study Shows 13-year Record of Drying Amazon Caused Vegetation Declines
Published Dec 11, 2014 - 6:42:39 AM
A 13-year decline in vegetation in the eastern and southeastern Amazon has been linked to a decade-long rainfall decline in the region, a new NASA-funded study finds
With global climate models projecting further drying over the Amazon in the future, the potential loss of vegetation and the associated loss of carbon storage may speed up global climate change.
Warmer Pacific Ocean could release millions of tons of seafloor methane
Published Dec 9, 2014 - 8:16:16 AM
Off the West Coast of the United States, methane gas is trapped in frozen layers below the seafloor. New research from the University of Washington shows that water at intermediate depths is warming enough to cause these carbon deposits to melt, releasing methane into the sediments and surrounding water.
