Antidepressants polluting the water can change fish behaviour
The new findings are published today in Biology Letters and coincide with a recent gathering of world experts to discuss the impacts of pharmaceutical waste on wildlife and how government agencies can draw on behavioural studies to monitor and regulate chemical pollutants in the environment. Psychoactive pollutants such as antidepressants, are increasingly detected in the environment and have long been shown to disrupt the behaviour of non-target species. “However, few studies have considered how the response of exposed organisms might be mediated by social context,” said lead study author Dr Jake Martin from the Monash University School of Biological Sciences. “Our research found that the antidepressant pollutant, fluoxetine (commonly marketed as Prozac™), did not alter behaviour of solitary fish but in a group setting, fluoxetine exposure disrupted the frequency of aggressive interactions and food consumption,” he said. “The results are significant because they suggest that behavioural tests in social isolation may not accurately predict the environmental risk of chemical pollutants for group-living species and highlight the potential for social context to mediate the effects of psychoactive pollutants in exposed wildlife.”
Reason to smile: happiness is the most dominant human expression, study finds
Smile, and the whole world smiles with you. A new Ohio State University study has determined that of the thousands of possibilities, there are but 35 universally accepted facial expressions. Yet perhaps most remarkable is that roughly half of these, 17 to be exact, are expressions of happiness. Unless we are actors, most of us are probably unaware of the myriad ways our faces can be reconfigured to express emotions, whether voluntarily or involuntarily. It turns out, however, humans are meant to smile much more often than they grimace, scowl, frown or wince. “This was delightful to discover,” says study coauthor Aleix Martinez, a cognitive scientist and a professor of electrical and computer engineering at the university, “because it speaks to the complex nature of happiness.” […] “We were shocked,” Martinez said. “I thought there would be way, way more. […] Happiness acts as a social glue and needs the complexity of different facial expressions,” explains Martinez. “Disgust is just that: disgust.”
Adolescent marijuana use may alter decision-making & self-control areas of the brain
As marijuana continues to be decriminalized across the United States, the dangers of children obtaining and using the drug are also coming into light. Now, a recent study shows how adolescent cannabis use could change the way neurons function in certain areas of teens’ brains, specifically the regions behind decision-making, planning, and self-control. […] “Our evidence suggests that exposure to cannabinoids during adolescence alters brain maturation in the prefrontal cortex,” says study leader Eliza Jacobs-Brichford in a university release. “These results may offer a mechanistic explanation for functional and behavioral changes caused by adolescent cannabinoid exposure.” […] The findings were presented at the annual meeting of the Society for Neuroscience in 2018.
Study: fish oil supplements have little to no effect on anxiety, depression
Omega-3 fatty acids, found in various nuts, seeds, and oily fish such as salmon, are undeniably good for you. Medical research has found this essential fat to be beneficial to eye, skin, and brain health, among other perks. Besides these physical benefits, omega-3s have also been touted as a mental health aid capable of alleviating and even completely preventing symptoms of anxiety and depression. A new study warns, however, that consuming fish oil supplements may not be so helpful when it comes to mental health after all. […] “This large systematic review included information from many thousands of people over long periods. Despite all this information, we don’t see protective effects,” comments lead author Dr. Lee Hooper in a release. “The most trustworthy studies consistently showed little or no effect of long-chain omega-3 fats on depression or anxiety, and they should not be encouraged as a treatment.”
National parks a boost to mental health worth trillions: study
National parks worldwide are worth about $8.7 trillion ($US6 trillion) a year in the improved mental health of their visitors, according to initial estimates published by a team of Griffith University researchers. Griffith ecologists, psychologists and economists led the peer-reviewed Perspective ‘Economic value of protected areas via visitor mental health’, which has been published in the prestigious journal Nature Communications. […] Using a concept called quality-adjusted life years, which measured a person’s ability to carry out the activities of daily life free from pain and mental disturbance, the researchers estimated the economic value of national parks […] “The article suggests several ways to calculate health services value, and these numbers are from just one of those methods – now we need to extend that research to other methods and other countries,” Professor Buckley said. “Protected areas are there for conservation, which gives us a liveable planet and underpins our entire economy, but conservation is not very powerful politically. People and politicians pay more attention to health, because it affects them personally.”
This result is based in part on research we posted here in June that quantified the minimum dose of nature needed to impart of life-changing (as opposed to short-term) improvement in mental health to be two hours per week.
Preventing Child Abuse & Neglect
What are child abuse and neglect?
These important public health problems include all types of abuse and neglect of a child under the age of 18 by a parent, caregiver, or another person in a custodial role (such as clergy, a coach, a teacher) that results in harm, potential for harm, or threat of harm to a child. There are four common types of abuse and neglect:
- Physical abuse is the intentional use of physical force that can result in physical Examples include hitting, kicking, shaking, burning, or other shows of force against a child.
- Sexual abuse involves pressuring or forcing a child to engage in sexual acts. It includes behaviors such as fondling, penetration, and exposing a child to other sexual activities.
- Emotional abuse refers to behaviors that harm a child’s self-worth or emotional well-being. Examples include name calling, shaming, rejection, withholding love, and threatening.
- Neglect is the failure to meet a child’s basic physical and emotional needs. These needs include housing, food, clothing, education, and access to medical care.
Child abuse and neglect result from the interaction of a number of individual, family, societal, and environmental factors. Child abuse and neglect are not inevitable—safe, stable, and nurturing relationships and environments are key for prevention. Preventing child abuse and neglect can also prevent other forms of violence, as various types of violence are interrelated and share many risk and protective factors, consequences, and effective prevention tactics. Using a public health approach, we can prevent child maltreatment before it starts.

Real-life telepathy proposed with “stentrode” brain implants!
Quietly over the past few months, the technology has started falling into place to allow people to communicate without words by transmitting their thoughts to each other via tiny, modem-like devices plugged into their brains. That’s right. Computer-aided telepathy. And it could become big business in the not-so-distant future. In April, a team of scientists from the University of Washington and Carnegie Mellon University published in the journal Nature a paper detailing an ambitious experiment they’d recently conducted. Three people worked together to play a crude version of the video game Tetris. Two of the research subjects could see the whole game screen–the falling blocks, the gaps in the stack of blocks at the bottom of the screen. Using only their thoughts, they beamed commands to a third person, whose own screen didn’t show the stack that the falling block needed to fit into. Sensing the commands from other two players, the third player rotated the block to fit.
An example of who we might, in the not-too distant future, be prodded to accept brain implants.
