Analysis of Paleolithic-era teeth from a 28,500-year-old fossil site in the Czech Republic provides supporting evidence for two groups of canids -- one dog-like and the other wolf-like - with differing diets, which is consistent with the early domestication of dogs.
Per- and polyfluoroalkyl substances (PFAS) are used in a wide range of consumer products, from pizza boxes to carpets to non-stick cookware. Therefore, it's not surprising that these water- and stain-repelling substances are ubiquitous in the environment. Now, researchers report in Environmental Science & Technology Letters that cats and dogs excrete some PFAS in their feces at levels that suggest exposures above the minimum risk level, which could also have implications for the pets' owners.
Thread-like parasitic worms cause millions of cases of canine heartworm each year, and more than 100 million cases of lymphatic filariasis, also known as elephantiasis, in humans. In research led by the University of Pennsylvania's Michael Povelones, ramping up the immune response of mosquitoes blocked their ability to transmit these harmful parasites.
Zoo improvements should benefit all animals and include a wide range of 'enrichment' techniques, researchers say.
Dogs that are smaller, younger, non-neutered, or live in US counties with high opioid prescription rates are at higher risk of being the subjects of phone calls about accidental opioid poisoning to a poison control center. Mohammad Howard-Azzeh and colleagues at the University of Guelph, Ontario, present these findings in the open-access journal PLOS ONE on Jan. 29, 2020.
Experiments performed by Brazilian scientists showed that Zika virus inhibits tumor cell proliferation even when inactivated by high temperature. The study was supported by FAPESP and published in Scientific Reports.
Pet dogs are highly receptive to commands from their owners. But is this due to their training or do dogs have an innate ability to understand human signals? A new study finds that 80% of untrained stray dogs successfully followed pointing directions from people to a specific location. The results suggest that dogs can understand and respond to complex gestures without any training, meaning that dogs may have an innate connection to human behaviors.
Most animals need to move, whether this is to seek out food, shelter or a mate. New research has shown that movement doesn't always break camouflage and if an animal needs to move, animals that are unpatterned and use short, fast movements are less likely to be located by predators.
Excessive activity of an immune system gene previously linked to schizophrenia reproduces neural and behavioral aspects of the disease in mice, according to a new study publishing on January 14 in the open-access journal PLOS Biology by Ashley Comer and Alberto Cruz-Martín of Boston University and colleagues. The finding provides mechanistic support for the importance of the gene in the development of schizophrenia, and may offer a new avenue for therapy development.
Increased body temperature is the single-most commonly noted abnormal finding for the medical practitioner. While it may be a sign of something relatively innocuous, it can also be an indication of underlying critical illness.
