There Once Was A….

Once again, there are three new pieces online on our website, each wonderful in its own way. But Haiku just didn’t seem to fit this batch. So, with apologies to the scientists, here are three limericks on the newest Institute research. As before, follow the links to get to our website. (Incidentally, there is some…

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…

A Genetic Balance of Terror

Cancer, we are told, is a disease of the genes. It originates in mutations in the DNA. But a paper published by a Weizmann Institute group in Cell Reports flips that idea sideways by about 90 degrees: For at least some types of the disease, the healthy, non-mutated version of a gene is no less…

Today’s Weizmann Institute news stories include two new papers from the prolific lab of Prof. Yadin Dudai. The first is on a protein that boosts memory in rats. Dudai and his group have been investigating this protein for several years. Previously, they had managed to show that blocking the protein, even for a very short…
