Published High H5N1 influenza levels found in mice given raw milk from infected dairy cows
(via sciencedaily.com) Original source Mice administered raw milk samples from dairy cows infected with H5N1 influenza experienced high virus levels in their respiratory organs and lower virus levels in other vital organs, according to new findings. The results suggest that consumption of raw milk by animals poses a risk for H5N1 infection and raises questions about its potential risk in humans.
Published Caterpillars can detect their predators by the static electricity they emit
(via sciencedaily.com) Original source Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists have found.
Published Designing a better nest to help endangered turtles
(via sciencedaily.com) Original source With Ontario's eight species of turtles considered at risk, a new nest designed by researchers has the potential to significantly bolster their struggling populations. The habitat is the first designed for turtles in rock barren landscapes, such as the research site around Georgian Bay. It uses moss and lichen. The researchers found that the design provided a more stable environment for incubating eggs compared to natural sites, where the probability of an egg hatching was only 10 per cent compared to 41 per cent in the created site.
Published Team enhances stereotactic neurosurgery precision using MRI-guided multi-stage robotic positioner
(via sciencedaily.com) Original source A research team developed an interactive multi-stage robotic positioner specifically designed for magnetic resonance imaging (MRI)-guided stereotactic neurosurgery.
Published Biodiversity in crabs: More than counting species
(via sciencedaily.com) Original source Researchers compare the shield shapes of crabs and find unexpected differentiation.
Published Finding the beat of collective animal motion
(via sciencedaily.com) Original source Virtual Reality experiments have illuminated the rhythmic glue that could keep animals moving in synchrony.
Published Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought
(via sciencedaily.com) Original source Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.
Published Escaped GMO canola plants persist long-term, but may be losing their extra genes
(via sciencedaily.com) Original source Populations of canola plants genetically engineered to be resistant to herbicides can survive outside of farms, but may be gradually losing their engineered genes, reports a new study.
Published Australian study proves 'humans are planet's most frightening predator'
(via sciencedaily.com) Original source A new study demonstrates that kangaroos, wallabies and other Australian marsupials fear humans far more than any other predator.
Published Researchers design new metal-free porous framework materials
(via sciencedaily.com) Original source Researchers have used computational design methods to develop non-metal organic porous framework materials, with potential applications in areas such as catalysis, water capture or hydrogen storage.
Published 3D printing robot creates extreme shock-absorbing shape, with help of AI
(via sciencedaily.com) Original source See how an autonomous robot created a shock-absorbing shape no human ever could -- and what it means for designing safer helmets, packaging, car bumpers, and more.
Published Improving statistical methods to protect wildlife populations
(via sciencedaily.com) Original source In human populations, it is relatively easy to calculate demographic trends and make projections of the future if data on basic processes such as births and immigration is known. The data, given by individuals, can be also death and emigration, which subtract. In the wild, on the other hand, understanding the processes that determine wildlife demographic patterns is a highly complex challenge for the scientific community. Although a wide range of methods are now available to estimate births and deaths in wildlife, quantifying emigration and immigration has historically been difficult or impossible in many populations of interest, particularly in the case of threatened species.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation
(via sciencedaily.com) Original source Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published Genes provide hope for the survival of Arabia's last big cat
(via sciencedaily.com) Original source The release of captive bred animals carefully selected for their genes can make a significant contribution to the successful recovery of the dwindling wild population and avert the prospect of extinction. Despite revealing extremely low levels of genetic diversity in the wild leopard population in Oman, the research team discovered higher levels of genetic diversity in captive leopards across the region. This important genetic resource has the potential for a major role in successful recovery of the Arabian leopard.
Published Meerkat chit-chat
(via sciencedaily.com) Original source Researchers unravel the vocal interactions of meerkat groups and show they use two different types of interactions to stay in touch.
Published Cooperative hunting requires less brainpower than previously thought
(via sciencedaily.com) Original source Through the use of artificial intelligence technology, a team of scientists has shown that advanced cognitive abilities are unnecessary for cooperative hunting. Their findings suggest that cooperative hunting, previously thought to be a complex social behavior seen primarily in mammals such as lions and chimpanzees, can also develop in species with lower levels of cognitive ability.
Published Robot-phobia could exacerbate hotel, restaurant labor shortage
(via sciencedaily.com) Original source Using more robots to close labor gaps in the hospitality industry may backfire and cause more human workers to quit, according to a new study. The study, involving more than 620 lodging and food service employees, found that 'robot-phobia' -- specifically the fear that robots and technology will take human jobs -- increased workers' job insecurity and stress, leading to greater intentions to leave their jobs. The impact was more pronounced with employees who had real experience working with robotic technology. It also affected managers in addition to frontline workers.
Published Cloudy waters causes African fish to develop bigger eyes
(via sciencedaily.com) Original source Variations in water quality can impact the development of the visual system of one species of African fish, suggests a new study.
Published Physicists propose path to faster, more flexible robots
(via sciencedaily.com) Original source Physicists revealed a microscopic phenomenon that could greatly improve the performance of soft devices, such as agile flexible robots or microscopic capsules for drug delivery.
Published Otters, especially females, use tools to survive a changing world
(via sciencedaily.com) Original source Sea otters are one of the few animals that use tools to access their food, and a new study has found that individual sea otters that use tools -- most of whom are female -- are able to eat larger prey and reduce tooth damage when their preferred prey becomes depleted.
