#RIP David Hubel. A #pioneer, #nobel prize winner, #inspiration, #neurophysiologist. This figure from an early paper of Dr. Hubel's shows "orientation selectivity": visual cortex #neurons fire more vigorously for bars of light presented at particular angles. A now ubiquitous concept that was unknown at the time this work was conducted. Thank you David. #science #neuroscience.

Increased #fruit consumption is recommended for #prevention of several #diseases including type 2 #diabetes. However, evidence supporting the preventative power of fruit consumption is mixed. Perhaps this is because of variability in the type of fruit consumed. Relying on a large #data-set from three #public #health studies: "66105 women from the Nurses’ Health Study (1984-2008), 85 104 women from the Nurses’ Health Study II (1991-2009), and 36 173 men from the Health Professionals Follow-up Study (1986-2008)", this work found that not all fruits are equal in combating type 2 diabetes. #science #medicine #bmj via #nature http://www.bmj.com/content/347/bmj.f5001

It is often claimed that #eating #breakfast can help one #lose #weight. A piece in the #nytimes points out that very few #clinicaltrials have addressed this question in a properly controlled manner. One study, shown here, found that there was no #statistical difference in weight lost by either eating or skipping breakfast (my underlining), rather those who switched their breakfast eating habits lost more weight than those that didn't (amongst a group of moderately #obese adults). On a personal note, I must admit I was surprised by this, having fully bought into the false claim that eating breakfast is helpful in losing weight. #science #medicine #obesity #diet #trustbutverify #ajcn http://ajcn.nutrition.org/content/55/3/645

A small group of #physicists believe that "physics will not be complete until it can explain how space and time emerge from something more fundamental". They believe that the #mindbending strangeness that results from considering #blackholes warrants the possibility of equally exotic basic mechanisms. Here are a few ideas being considered. #science #nature http://www.nature.com/news/theoretical-physics-the-origins-of-space-and-time-1.13613

Removing a portion of the #stomach (#gastrectomy) can partially diminish the weight gain induced by a high fat #diet (HFD), but it appears that the effects of these factors can propagate to the next generation. This work in #rats showed that #triglyceride and #cholesterol levels in offspring were modulated both by their mothers' diet ("oHFD" vs "oChow" control) AND by whether the mother had undergone a gastrectomy ("VSG" vs "Sham"). #science #medicine #obesity #epigenetics #sciencetranslationalmedicine http://stm.sciencemag.org/content/5/199/199ra112

It has been demonstrated that #skinny people and #fat people have different types of #gut #bacteria. New work shows this is not only #correlation, but indeed extends to #causation. Researchers found several pairs of #human #twins in which one twin was #obese and one was #lean and transplanted their respective gut bacteria to both obese and lean #mice. They found that the #microörganisms from an obese twin caused lean mice to gain #weight, while those from a lean twin caused lean mice to #lose weight and #bodyfat. #science #medicine #obesity #physiology #bacteriome. #nytimes via #sciencemagazine http://www.sciencemag.org/content/341/6150/1241214 http://nyti.ms/13jNs9k

As we #age, #cognitivecontrol changes: single task #focus improves as #multitasking ability worsens. A new study shows that #videogame #training can improve #reactiontime in adults as old as 80+ such that their performance resembles that of 20-somethings. Impressively, this improvement remains at least 6 months after training. It is unclear whether this improvement has a cost, however: does multitasking improvement necessarily reduce single task focus? Unknown as yet… #science #neuroscience #aging #nature via #nytimes http://www.nature.com/nature/journal/v501/n7465/full/nature12486.html http://nyti.ms/17uoWQ1
