By the 2030s, every second summer over almost all of the entire Northern hemisphere will be hotter than any record-setting hot summer of the past 40 years. By 2050, virtually every summer will be hotter than anything we've experienced to date.

Living in the fallout zone from a nuclear disaster would be no worse for our health than living in London, due to its scale of pollution.

The most dramatic divergence between humans and other primates can be found in the brain. Our brains are three times larger, have many more cells, and one gene involved in the production of dopamine was highly expressed in human neocortex and striatum but absent from the neocortex of chimpanzees.

Cinnamaldehyde, an essential oil that gives cinnamon its flavor, may improve metabolic health. The ingredient induces fat cells, or adipocytes, to start burning energy through a process called thermogenesis.

Smart people have better connected brains - In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.

Avatar therapy 'reduces power of schizophrenia voices': Confronting an avatar on a computer screen helped patients hearing voices to cope better with hallucinations. Patients who received this therapy became less distressed and heard voices less often compared with those who had counselling instead.

Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published in Nature Communications and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.

The plague-causing bacterium may have first come to Europe with the large-scale migration of steppe nomads in the Stone Age, millennia before the first known historical epidemics. Findings also confirm plague bacteria undergoing genetic mutations related to its virulence at the time of its arrival.

The human genome project sequenced our DNA to give a “parts list” for a person. Now, researchers are pushing that understanding further by mapping out the tissue-specific expression of these genes in humans (44 tissues and 449 tissue donors)

Scientists created a mini biohybrid robot using algae, to travel through people in response to magnetic signals, that could one day carry drugs to specific parts of the body, minimizing side effects. What’s more, the robot—and its magnetic coat—appear to kill cancer cells.

9 SirT6 To what extent does the source of the sugar matter in terms of how it impacts neuronal plasticity and other behavioral traits related to addiction? It looks like in your study, you supplied the rats with 5% sucrose laden drinking water. Do you think you would have seen similar results if the rats had been fed a fruit-based diet that is high in sucrose. Also, I am having a hard time understanding exactly how sugary 5% sucrose water would be. What is the sucrose content of a soda, for example, by comparison?

4 postdochell What about non-caloric sweeteners? It it simply the sensory experience of "sweet" or does it also require a caloric component?
3 divvyflax Regarding your study itself, I'm curious to hear a bit about your choice to use adolescent rats. Is this effect likely to be any different at different developmental stages? More generally, I'd be interested to know how you approach sugar consumption in your day-to-day life. It's certainly more ubiquitous that alcohol.
3 forgetremembering Would there be any merit to testing the sucrose solution with a soluble fiber like inulin to measure if the presence of an indigestible carbohydrate in any way mitigates the effect the fructose has on the brain?
2 PHealthy Hi and thanks for joining us today! This may be quite a reach but with countries implementing sugar taxes and seeing lowered consumption levels, do you think we might also see a correlated uptick in depression and suicide?
2 VoidsIncision Can these changes be reversed by ceasing or reducing consumption? Would the brain try and replace the "soothing" with something else until the underlying traumas are dealt with?
2 ombwtk 1) What is the threshold for overconsumption? 2) Does the packaging seem to matter (e.g. fruit vs fruit juice vs candy)? 3) Could you briefly explain what lead you to your hypothesis? Is it that sugar and alcohol cause similar reactions in the brain when ingested and so you project that sugar will have similar long-term consequences? 4) Do you know if any other component of a macronutrient has been analysed like this? If so, how did it compare to sugar? Thanks!
1 lucaxx85 Hi there! I'll ask what I think is the most obvious follow up question. Do you think that this similarity between sugar and alcohol is due to some specific biochemical similarity in the substances or because of similarities in the addiction mechanism, which can involve many addictions, even unrelated to "drugs" (e.g.: problematic gamblic).
1 6thGenTexan Wasn't there research being done on obese people and the number of sweet taste receptors on their tongues? I've known some morbidly obese people that seemed to get more of a kick from sugar than is normal. I agree with your hypothesis about sugar and alcohol. I think alcoholism is really an eating disorder and can be treated as such. I know from personal experience that if one eliminates sugar from their diet, you will stop craving sweets. I have also noticed that a high protein snack alleviates cravings for sugar. What could be the mechanism for this?
