Male guppies exposed to predators in the wild or in captivity have heavier brains than those living in relatively predator-free conditions, according to new research published in the journal Functional Ecology.
Behavioural ecologists from Liverpool John Moores University, UK and McGill University, Canada sampled guppies from two rivers in northern Trinidad. In each river, guppies live above a waterfall, a location that only guppies and a few other small species of fish have managed to colonize, and below the fall, where many predators including pike cichlids live.
Pilot study results indicate that a sleep and yoga intervention has promising effects on improving sleep disturbance, sleep-related impairment, and sleep health behaviors.
Sleep problems are very common in low income communities yet often under-recognized and untreated, and are often related to sleep health behaviors, stress, and adverse environmental conditions. This study researched how to effectively deliver sleep health education and yoga interventions in underrepresented communities.
A tailored lighting intervention in nursing homes can positively impact sleep, mood and behavior for patients with Alzheimer's disease, according to preliminary findings from a new study.
People with Alzheimer's disease and related dementias may experience sleep problems, wandering, and associated daytime irritability. This study tested whether a tailored daytime lighting intervention could improve sleep and behavior in Alzheimer's patients living in long-term care facilities.
Tens of thousands of sea turtles are caught each year by small-scale fishers off South America's Pacific coast, new research shows.
Surveys at 43 harbours in Ecuador, Peru and Chile reveal that gillnet fisheries catch more than 46,000 sea turtles per year, with more than 16,000 killed in the process.
And the true numbers are likely to be higher, as not all ports in each country were surveyed.
Maternal depressive mood during the prenatal and postnatal periods is related to child sleep disturbances, according to recent pilot data from a longitudinal cohort study in kindergarten children.
Shareholder value and market share improve when companies merge, confirms a new study from the University of Waterloo.
The study also found that the new company's market share ended up being greater than the market share of the two merged companies combined.
Differences in the structure of the prefrontal cortex predict an individual's ability to make healthier food choices, according to a new analysis of previous research in healthy men and women. The paper, published in JNeurosci, suggests an important role of these anatomical markers in decisions that have long-term effects on health and wellbeing.
Bumper car-like interactions at the edges of our solar system—and not a mysterious ninth planet—may explain the dynamics of strange bodies called “detached objects,” according to a new study.
CU Boulder Assistant Professor Ann-Marie Madigan and a team of researchers have offered up a new theory for the existence of planetary oddities like Sedna. This minor planet orbits Earth's sun at a distance of 8 billion miles but appears separated from the rest of the solar system.
URBANA, Ill. - In the fight against herbicide resistance, farmers are working with a shrinking toolkit. Waterhemp, a weedy nemesis of corn and soybean farmers, has developed resistance to multiple herbicide modes of action, often in the same plant. Even farmers using the latest recommendations for tank mixtures are fighting an uphill battle, with long-distance movement of pollen and seeds bringing the potential for new types of resistance into their fields each year.
The future of cardiovascular care will be transformed by advances in artificial intelligence, digital health technology, and mobile as a means to prevent and treat heart disease, according to several review articles published today in a Journal of the American College of Cardiology Focus Seminar on the Future Technology of Cardiovascular Care.

Even though men don't often talk about their body insecurities, a new survey finds it's something that's certainly on their minds. Instead of discussing the issue or seeking advice from their doctors, men often turn to supplements and extreme workout regimens to change their bodies. A national survey commissioned by Orlando Health finds that 90 percent of men have changed their daily habits to reach their fitness goals.
Inadequate sleep is a public health problem affecting more than one in three adults worldwide. A new study in the journal SLEEP, published by Oxford University Press, suggests that insufficient sleep could also have grave economic consequences.
BALTIMORE - The key to predicting how someone is affected by sleep loss may be found in microRNAs (miRNAs), according to a new study from researchers at the Perelman School of Medicine at the University of Pennsylvania. Many studies connect sleep loss with cancer, cardiovascular disease, Alzheimer's, and other disorders, and it is well known that sleep loss negatively affects cognitive performance. However, those adverse effects are experienced differently from person to person, and little is known about how to accurately predict and detect these individual sleep-deprivation deficits.
Japan -- Even bonobos lose their appetites with enough 'ick'.
These primates, known for their liberal attitudes toward sex, are also generally open-minded when it comes to new foods -- as long as the grub is clean.
Researchers from Kyoto University's Primate Research Institute have now found that a bonobo's curiosity transforms into caution when food is presented with or near feces, soil, or bad smells. Their study was published in the journal Philosophical Transactions of the Royal Society B.
Policymakers are being misinformed by the results of economic models that underestimate the future risks of climate change impacts, according to a new journal paper by authors in the United States and the United Kingdom, which is published today (4 June 2018).
The paper in the Review of Environmental Economics and Policy calls for the Intergovernmental Panel on Climate Change (IPCC) to improve how it analyses the results of economic modelling as it prepares its Sixth Assessment Report, due to be published in 2021 and 2022.
