Hesperos reports the successful testing of multi-organ 'human-on-a-chip' models to recapitulate the 28-day experiments typically used in animals to evaluate the systemic toxicity of drug and cosmetic compounds. The work is published in Advanced Functional Materials.
This research letter documents bone cancer in a 240-million-year-old stem-turtle from the Triassic period, helping to provide more data about the history of cancer in tetrapod evolution. This is a case study about a highly malignant bone tumor on the femur of a shell-less stem-turtle.
At least 200 species of large animals are decreasing in number and more than 150 are under threat of extinction, according to new research that suggests humans' meat consumption habits are primarily to blame.
Introduced and invasive species can present big problems, particularly when those species are charismatic. Some introduced species, like zebra mussels, tend to be reviled by the public, and people willingly adhere to strict management policies. However, if an animal has that elusive quality of charisma, people often don't want it to be controlled, even if it's harming the environment. Inevitably, these imbalances in public perception of introduced species influence the way those organisms are managed.
In a paper recently published in the journal Frontiers in Veterinary Science, a team of researchers, animal care experts and veterinarians evaluate the balance between animal welfare and conservation needs for a number of rare species of native birds being raised in San Diego Zoo Global breeding centers in Hawaii. The paper shares the challenges and complexity of situations where the needs of an individual and the needs of a species are weighed, and how that balance is achieved.
For the first time, researchers at the University of Missouri have catalogued every pollinator protection policy enacted by state governments from 2000-2017. The resulting database of information allows everyone from legislators to the general public to study how state lawmakers have addressed the pollinator health crisis over time.
Many non-vegan vegetarians and omnivores are open to including insects in their diet. For vegans, however, that is not an option, a new study from the University of Eastern Finland shows. Researchers examined consumers' intentions to consume foods of insect origin among vegans, non-vegan vegetarians and omnivores. They examined the attitude, subjective norm, perceived behavioral control and food neophobia toward the consumption of foods of insect origin, as well as the conditions for eating insect-based foods among these dietary groups.
A study focusing on the type and volume of seizures relating to illegal wildlife trade in Hong Kong over the last five years, documented in the report, 'Trading in Extinction: The Dark Side of Hong Kong's Wildlife Trade,' illustrate the city's central role in global wildlife trafficking and the extent and nature of the associated criminality. It identifies clearly, how future policy and enforcement could be improved to provide the urgently required long-term sustainability.
Now published: the first issue of Ethics & Human Research, replacing The Hastings Center's longstanding journal, IRB: Ethics & Human Research, is "widening the lens" on new ethical, policy and regulatory challenges raised by rapid developments in science and medicine.
A new study published in The Condor: Ornithological Applications shows that certain endangered owls may continue to persist and even flourish after large forest fires.
