Releasing The Neuronal Brakes For Learning

Learning can only occur if certain neuronal "brakes" are released. As the group led by Andreas Lüthi at the Friedrich Miescher Institute for Biomedical Research has now discovered, learning processes in the brain are dynamically regulated by various types of interneurons. The new connections essential for learning can only be established if inhibitory inputs from [...]

Hopefully, Literally, Begs The Question: The Three Most Annoying Misuses In English

Atrocities in English are committed every day. Here are three of the worst. You may be surprised, but hopefully you won’t literally explode with anger. When we talk of words, even if we don’t know it, we tend to divide ourselves into two schools of thought - the descriptivists and the prescriptivists. Prescriptivists tend to [...]

Multiculturalism Faces Uncertain Future In Our More Polarised Nation

Australia seems to be becoming a more polarised society. This is the simple conclusion from recent research undertaken for SBS, which looked for answers to how Australians think the country has changed over the past 20 years, and where they think it may be in another 20 years. A more “traditionalist” group perhaps as high [...]

Porn May Be Messing With Your Head

Men who report watching a lot of pornography tend to have less volume and activity in regions of the brain linked to rewards and motivation, says a new German study. The results provide the first evidence for a link between pornography consumption and reductions in brain size and brain activity in response to sexual stimuli. [...]

Limiting Screen Time Yields Multiple Benefits

  Parents may not always see it, but efforts to limit their children's screen time can make a difference. A new study, published in JAMA Pediatrics, found children get more sleep, do better in school, behave better and see other health benefits when parents limit content and the amount of time their children spend on the [...]

Alcohol Culture Change: The First Signs?

Over the last fortnight it’s been interesting to read the reporting about the release of a couple of key pieces of alcohol data in Australia. The Australian Bureau of Statistics released its Apparent Consumption of Alcohol, Australia, 2012-13 report, which shows Australians are drinking less alcohol overall than any time in the previous 15 years. [...]

Harvesting Happiness Instead Of Chasing It

Every day, it seems, we are bombarded with advertisements, memes and well-meaning emails telling us how to “be happy.” Despite this, a new study led by Stanford University reveals that chasing happiness may actually make us less happy. The new research, published in the Journal of Experimental Social Psychology, does, however, point to effective ways [...]

Stop Stressing Me Out

Chatting with a highly stressed work colleague recently, she revealed she’d recently spent thousands on treating the symptoms of stress – from heart palpitations to problems with her digestive system. I was shocked – how have things become so bad young people are suffering from heart problems at work? I thought it would be a [...]

One in 13 US schoolkids takes psych meds

More than 7 percent of American schoolchildren are taking at least one medication for emotional or behavioral difficulties, a new government report shows. Apparently, the medications are working: More than half of the parents said the drugs are helping their children, according to the report. - Serena Gordon   via One in 13 US schoolkids takes [...]

Researchers model neural structures on the smallest scales to better understand traumatic brain injury

Compared to the monumental machines of science, things like the International Space Station or the Large Hadron Collider, the human brain doesn't look like much. However, this three-pound amalgam of squishy cells is one of the most complicated and complex structures in the known universe.   - Evan Lerner   via Researchers model neural structures on [...]
