Animal-Assisted Therapy (AAT) is a fairly new practice whose underlying principles date back to the beginning of time. Man has always found companionship in animals, but now researchers, educators and therapists are finding that by drawing on that comfort, children and adults can attack physical, mental and emotional issues. The use of animals in…

Cognitive impairments resulting from traumatic brain injury (TBI) are often long-lasting and difficult to remediate. These include problems with thinking, memory, reasoning, expressing and understanding emotion, social communication and social appropriateness. Survivors are often limited in their ability to return to a previous level of…

Achieving a clearer picture of categorial distinctions in the brain is essential for our understanding of the conceptual lexicon, but much more fine-grained investigations are required in order for this evidence to contribute to lexical research. Here we present a collection of advanced data-mining techniques that allows the category of individual…

Genetic studies in "Drosophila" have revealed two separable long-term memory pathways defined as anesthesia-resistant memory (ARM) and long-lasting long-term memory (LLTM). ARM is disrupted in "radish" ("rsh") mutants, whereas LLTM requires CREB-dependent protein synthesis. Although the downstream effectors of ARM and LLTM are distinct, pathways…

Physical activity improves learning and hippocampal neurogenesis. It is unknown whether compounds that increase endurance in muscle also enhance cognition. We investigated the effects of endurance factors, peroxisome proliferator-activated receptor [delta] agonist GW501516 and AICAR, activator of AMP-activated protein kinase on memory and…

The author visited the Galapagos Islands in 2009 and here looks at their biodiversity through pictures taken then. The diverse habitats of the Islands are reflected in the great diversity of flora and fauna found on them, with many species endemic to the Islands. The stories of the land iguanas, control of introduced species and the giant…

Operation Cleansweep is a free pesticide disposal program that has operated in Florida since 1995. The program is open to commercial facilities, including agricultural production establishments, golf course operators, and pest control companies. Since its inception, the program has had more than 1,700 participants and collected more than 1,000,000…

Research on the role of the hippocampus in object recognition memory has produced conflicting results. Previous studies have used permanent hippocampal lesions to assess the requirement for the hippocampus in the object recognition task. However, permanent hippocampal lesions may impact performance through effects on processes besides memory…

A recent study has revealed that fear memory may be vulnerable following retrieval, and is then reconsolidated in a protein synthesis-dependent manner. However, little is known about the molecular mechanisms of these processes. Activin [beta]A, a member of the TGF-[beta] superfamily, is increased in activated neuronal circuits and regulates…

In the summer of 2008, the Spanish legislature resolved to grant great apes (though not all simians) basic human rights. While the decision to grant such rights came about largely through the lobbying efforts of the Great Ape Project (GAP), the decision has potential reverberations throughout the scientific world and beyond in its implications for…

The titrating-delay matching-to-sample (TDMTS) procedure offers researchers an additional behavioral task thought to capture some important features of remembering. In this procedure, the delay between sample offset and comparison onset adjusts as a function of the subject's performance. Specifically, correct matches increase the delay and…

Mainstream scientists often claim that australopithecines such as the specimen nicknamed "Lucy" exhibit anatomy intermediate between that of apes and that of humans and use this as evidence that humans evolved from australopithecines, which evolved from apes. On the other hand, creationists reject evolution and claim that australopithecines are…

The present study assessed the effects of systematically separating the cue from the response in temporally defined schedules of delayed signaled reinforcement. Identical schedules were used to study the effects of the independent variable on response acquisition and response maintenance. In the first experiment, 8 groups of 3 naive rats were…

A neutral olfactory stimulus was employed as CS in a series of experiments with a sexually receptive female as UCS and the execution of an intromission as the UCR. Each experimental session lasted until the male ejaculated. The time the experimental subject spent in a zone adjacent to the source of the olfactory stimulus during the 10 s of CS…

This essay challenges science's traditional taboo against anthropomorphizing animals or considering their behavior as indicative of feelings similar to human emotions. In their new book "Wild Justice: The Moral Lives of Animals," the authors argue that anthropomorphism is alive and well, as it should be. Here they describe some…
