Facial recognition app for dogs developed to help in fight against rabies      (via sciencedaily.com)     Original source 

A new mobile phone-based facial recognition application for dogs has the potential to significantly improve rabies vaccination efforts in endemic areas like Africa and Asia, according to a new study. A team used the app to test its effectiveness at a rabies vaccination clinic in rural Tanzania where they microchipped, vaccinated and registered dogs. The technology proved remarkably accurate during a subsequent visit to surrounding villages once poor images and improperly recorded information were removed from its database. Using the app, operators identified 76.2% of vaccinated dogs and 98.9% of unvaccinated dogs.

New pieces in the puzzle of first life on Earth      (via sciencedaily.com)     Original source 

Microorganisms were the first forms of life on our planet. The clues are written in 3.5 billion-year-old rocks by geochemical and morphological traces, such as chemical compounds or structures that these organisms left behind. However, it is still not clear when and where life originated on Earth and when a diversity of species developed in these early microbial communities. Evidence is scarce and often disputed. Now, researchers have uncovered key findings about the earliest forms of life. In rock samples from South Africa, they found evidence dating to around 3.42 billion years ago of an unprecedentedly diverse carbon cycle involving various microorganisms. This research shows that complex microbial communities already existed in the ecosystems during the Palaeoarchaean period.

Gulls swap natural for urban habitats, machine-learning study finds      (via sciencedaily.com)     Original source 

The study is the first of its kind to compile a three-year dataset using a citizen science-based, opportunistic research method to include a large sample of gulls and other sub-Arctic birds in urban Alaska. The study provides a current snapshot of the habitat shift to an urban landscape.

New research into hedgehogs injured by robotic lawn mowers discovers a significant but solvable animal welfare and conservation problem      (via sciencedaily.com)     Original source 

Scientists analyzed 370 documented cases of hedgehogs being injured (cut) by electric gardening tools in Germany. Almost half of the hedgehogs found between June 2022 and September 2023 did not survive the injuries. The data reveal a serious animal welfare and conservation issue for these specially protected animals, as most hedgehogs were only found hours or even days after the accidents.

The megalodon was less mega than previously believed      (via sciencedaily.com)     Original source 

A new study shows the Megalodon, a gigantic shark that went extinct 3.6 million years ago, was more slender than earlier studies suggested. This finding changes scientists' understanding of Megalodon behavior, ancient ocean life, and why the sharks went extinct.

Knowing what dogs like to watch could help veterinarians assess their vision      (via sciencedaily.com)     Original source 

A veterinary ophthalmologist wanted to determine factors, including age and vision, that influence a dog's interest in interacting with video content. Ultimately, the goal of the study, which launched two years ago, was to support development of more sensitive ways to assess canine vision -- something that has been sorely lacking in veterinary medicine. The study found that dogs are most engaged when watching videos that feature other animals.

Sea otters helped prevent widespread California kelp forest declines over the past century      (via sciencedaily.com)     Original source 

The study reveals dramatic regional kelp canopy changes along the California coast over a 100-year period. During this time there was a significant increase in kelp forest canopy along the central coast, the only region of California where southern sea otters survived after being hunted nearly to extinction for their fur in the 1800s. Contrastingly, kelp canopy decreased in northern and southern regions. At the century scale, the species' favorable impact on kelp forests along the central coast nearly compensated for the kelp losses along both northern and southern California resulting in only a slight overall decline statewide during this period.

Butterflies could lose spots as climate warms      (via sciencedaily.com)     Original source 

Female meadow brown butterflies have fewer spots if they develop in warmer weather -- so climate change could make them less spotty, new research shows.

Ancient 'chewing gum' reveals stone age diet      (via sciencedaily.com)     Original source 

What did people eat on the west coast of Scandinavia 10,000 years ago? A new study of the DNA in a chewing gum shows that deer, trout and hazelnuts were on the diet. It also shows that one of the individuals had severe problems with her teeth.

Researchers found that wolf spiders can't signal others or perceive danger from predators as easily on rain-soaked leaves compared to dry ones. Even communicating with would-be mates is harder after it rains.

A study has found some surprising features in two new species of burrowing scorpions, including a very strangely shaped 'tail tip' and some 'sexy' anatomy features. Terrestrial biologists have taken a closer look at two new species of the mysterious Urodacus genus of burrowing scorpions endemic to Australia -- only to find a big difference in their tails compared to other species.

Tiny AI-based bio-loggers revealing the interesting bits of a bird's day      (via sciencedaily.com)     Original source 

Researchers have developed a bio-logger for seabirds that enables long-term observation of rare behaviors. The bio-logger employs low-power depth sensors and accelerometers to identify rare behavior using a light-weight outlier detection model and records the behavior in a 5-min video. Observations using the bio-loggers on Streaked Shearwaters revealed novel aspects of head-shaking and foraging strategies. This approach will enable a wider range of animal behaviors in various environments to be observed.
