Could artificial sweeteners be helping cause the very thing they are supposed to prevent? They may well do so, and you can probably blame your microbiota – those masses of mostly-friendly bacteria that live in your gut. According to a paper by Weizmann Institute scientists that appeared today in Nature, artificial sweeteners not only encourage…

At the level of biomolecules, life boils down to two basic principles: sequence and folding. We know, for example, that the sequence of nucleotides in the DNA contains our genetic blueprint, but the way that our DNA is folded and wrapped up in each chromosome helps determine which genes are easily accessible for copying. Proteins…

Science Haiku 3×3

More science-themed haikus. I seem to keep writing them because we tend to put out three “mini press releases” at a time (a relic of the days when they were printed on two sides of a fold-up page and mailed). So I could pick just one to blog about, or I could try to fit…

DNA testing can reveal how closely related you are to a group of people halfway around the world or, if you’re doing evolutionary research, where organisms fit on taxonomic trees. The same DNA tests, when performed on the cells in a single human body, can be used to reconstruct lineage trees that can trace the…
