The study's results support the idea that fast and accessible treatment can increase survival rates in snakebite victims.
Scientific collections provide wealth of information on species' diet, breeding habits, growth rates, lifespan, and ecology. Collections have played crucial role in understanding climate change impacts and disease tracking, with discoveries like de-extinction of the Vegas Valley leopard frog.
The California Academy of Sciences discovered 91 new plant and animal species in 2013, including 38 ants, 12 fishes, and 14 plants. This finds highlights the importance of biodiversity hotspots like Madagascar and the need for continued exploration and conservation efforts.
A novel approach to treating venomous snakebites involves administering antiparalytics topically via a nasal spray, which has been shown to counteract paralysis in minutes. The treatment has the potential to dramatically reduce global snakebite fatalities, currently estimated at 125,000 per year.
A series of scientific papers reveals early human species like Australopithecus afarensis and Kenyanthropus platyops began eating grasses, sedges, and succulents around 3.5 million years ago. The findings show that early humans acquired a taste for C4/CAM plants after their environments seemed similar to their ancestors.
The California Academy of Sciences has described 137 new species across four continents and two oceans, adding to the complex web of life on Earth. These discoveries strengthen conservation efforts by providing a deeper understanding of evolution and the persistence of life.
The study of Australopithecus afarensis shoulder blades reveals a partially arboreal lifestyle. The fossils show an apelike shape, indicating the species was adapted for climbing trees in addition to walking on two legs.
An international team of scientists assesses 163 grouper species and finds 20 at risk of extinction, while 22 are Near Threatened. Groupers take years to mature and are vulnerable to overfishing and habitat loss.
A new species of deep-sea catshark has been described from the Galapagos Islands, characterized by its chocolate-brown coloration and pale, irregularly distributed spots. The species is found at depths of 1,400-1,900 feet and is believed to be susceptible to overfishing due to its restricted range.
Scientists have recorded the first association between a black-marble jawfish and a mimic octopus. The jawfish sticks close to the octopus for protection, allowing it to venture away from its burrow to look for food. This unique case highlights the complex interactions within coral reef ecosystems.
The California Academy of Sciences discovered 140 new species in 2011, including arthropods, sea slugs, fishes, plants, sponges, corals, and a reptile. These findings add to the family tree of life on Earth and provide crucial information for conservation decisions.
The California Academy of Sciences is conducting a comprehensive survey effort in the Philippines to document terrestrial and marine life forms. The expedition aims to discover new species, map their distribution, and inform conservation decisions.
A research team used 100-year-old specimens from California Academy of Sciences to estimate when avian pox hit Galapagos. The study found that humans likely played a role in spreading the disease, highlighting the need for policies to prevent further spread.
A new assessment reveals that 20% of the world's vertebrates are currently threatened with extinction, with 52 species moving closer to extinction each year. The study highlights the alarming rate of decline among vertebrate species globally.
Researchers used DNA analysis to identify the Passenger Pigeon's closest living relatives, revealing that it was most closely related to other North and South American pigeons, not the Mourning Dove. The study also sheds light on the bird's extinction, which was caused by human hunting and habitat destruction.
Researchers analyzed DNA sequences to understand how the Thaumoctopus mimicus evolved its ability to impersonate flatfish, displaying high-contrast color patterns. The study found that this trait is an extremely risky defense strategy, but one that allows the octopus to survive and reproduce more successfully in its habitat.
The discovery of fossilized bones with cut marks in Ethiopia pushes the timeline of stone tool use and meat consumption back by nearly a million years. The evidence suggests that early human ancestors, such as Australopithecus afarensis, used stone tools to butcher meat from large mammals.
Researchers collecting mollusk specimens from the Gulf Coast will analyze growth rings in shells to determine how quickly harmful compounds from the oil become incorporated into the animals' bodies. They will also test for hydrocarbons in tissues and measure changes in growth rate and survivorship.
A new study calculates that ecosystems will need to shift about 0.42 kilometers per year to keep pace with global climate change over the next century. Mountainous habitats can move more slowly, while flatter ecosystems must move rapidly.
Researchers have named a new species of chimaera, an ancient group of fishes distantly related to sharks, from the coast of Southern California and Baja California. The Eastern Pacific black ghostshark (Hydrolagus melanophasma) is known from nine preserved museum specimens and video footage taken of it alive in deep water.
