Research finds that certain small RNA molecules can trigger a mechanism hidden in every cell that forces it to self-destruct. This failsafe may protect us from cancer. The mechanism could potentially become a novel form of cancer therapy, the study authors say.

Migraines may be brain’s way of dealing with oxidative stress. Migraines affect approximately 14 percent of the world's population, or 1.04 billion people. In the United States alone, migraine causes an estimated $36 billion annually in lost productivity, including 113 million lost work days.

Plasma technology could hold the key to creating a sustainable oxygen supply on Mars, a new study has found. It suggests that Mars, with its 96% carbon dioxide atmosphere, has nearly ideal conditions for creating oxygen from CO2 through a process known as decomposition.

Snakes and spiders evoke fear and disgust in many people. There has been debate about whether this aversion is innate or learnt. Scientists discovered that babies as young as six months old feel stressed when seeing these creatures, long before they could have learnt this reaction.

Stanford scholars have probed how Americans think about mental life. Most people don’t have answers to the big questions about consciousness or the meaning of life, but they do have a way of thinking about and categorizing mental life. It comes down to three things – body, heart and mind.

Crows share an interesting set of behaviors with humans: they like to play, and they often use tools. Scientists investigate why crows are so playful, and found that the birds who played with tools in an experiment were much better at using those tools in a food-finding task.

242 Kenitzka The first question naturally will be, "how do I change my gut bacterial composition?" *Will this give birth to a new wave of suppository nutritional products and colon fecal transplants?
63 natura_simplex_ One thing I noticed is that the authors have a patent for weight loss prediction biomarkers. Not sure how that might have biased their results, or if they may have focused mainly on what they wanted to prove versus all possible explanations. It seems like the study found no difference between the two diets for people with the low P/B community (no matter what you eat, you can't lose weight if you have low P/B), while people with high P/B community lost weight on the "new" high protein, hgh fiber, low fat diet with lots of fruits and vegetables. It seemed that, on both diets, partipants were allowed to eat ad libitum, which makes me wonder if the total calories consumed could explain the success of the high protein, high fiber diet. Many dieters claim high protein, high fiber is more satiating than high carb diets, so perhaps partipants ate less calories on the more satiating diet. This wouldn't explain why P/B ratio correlates with weight loss, though, so there's still something to further investigate there. The authors note that only two partipants switched P/B ratio throughout the study, suggesting that diets high in fiber don't affect P/B ratio. Maybe this means, before dieting, some other intervention is required (dietary or drug?) for successful weight loss. I do still wonder how total calories or other dietary components affect the results, or if total calories or other dietary components influence gut microbe communities in ways protein and fiber don't.
9 sorryaboutlastnight Were the two different diets matched in terms of total calories consumed?
22 dem0n0cracy Don't Western diets have high sugar contents, and are the more important macro to be aware of?
16 MayorNarra Did each of they groups eat an equivalent amount of calories? If not, I would say the results of the study should not be viewed as conclusive.
4 UnprovenMortality "The research team found that relationship between two groups of intestinal bacteria was decisive for whether overweight people lose weight on a diet that follows the Danish national dietary recommendations and contains a lot of fruit, vegetables, fiber, and whole grains." My next question would be: are these gut bacteria important because participants were placed on a high plant matter diet? Or can these results be replicated on a keto diet/western diet with calorie restriction?
3 Final7C So the question is: Are the people eating the New Nordic diet creating gut bacteria composition that allows them to lose more weight, and the danish national diet does not actively feed that specific biome? Or do the people naturally have that gut biome and it is maintained by some other source?
