Does the brain really operate like some kind of extra-complex computer, with logic gates and circuits made of the synapses that connect one neuron to another? In 2009, we wrote: In the future, the interface between brain and artificial system might be based on nerve cells grown for that purpose. In research that was recently…

Rates of melanoma are increasing, even as the rates of other common cancers are decreasing. According to the Melanoma Research Alliance, it is the most common cancer diagnosis in young adults 25-29 years old in the United States, the second most common cancer in young people 15-29, and its incidence has tripled in the last…

Ziv Zwighaft is a research student in the group of the Weizmann Institute’s Dr. Gad Asher. Their new findings reveal some intriguing connections between our circadian clocks – which tick according to cycles of day and night – metabolism and aging. Here is his description: King Solomon said: “There is a time for everything, and…

    One day in the future, we may be treating our ailments with microbiotic combinations designed specifically to correct imbalances in our personal microbiomes. We’ll bring our prescriptions on rewritable paper and pay using shimmery optical chips embedded in our cell phone cases or maybe our jewelry. Or we’ll be waiting in our doctor’s…

When Dr. Jakub Abramson was a 14-year-old boy in the former Czechoslovakia, he asked his father what was the best place to do science. His father took the question seriously and, after some consideration, answered “the Weizmann Institute of Science.” Since that day, says Abramson, he knew he was bound for the Institute. “It’s just…

What is a breakthrough in cancer research? It is a new piece of a puzzle made up of a million pieces. It may, however, be a piece that allows a picture to start emerging – one that lets us see the shape of the next piece needed to fill in more of the puzzle, or…

“Inclusion bodies – those clumps of protein that are found in the brain cells of Alzheimer’s patients – are, sadly, a product of aging,” says Dr. Maya Schuldiner. “They can form naturally in practically all cells, but when these cells get old, the mechanism for clearing them away starts to fail.” That is not great…

Foreigner or native-born? Your immune system discriminates between them, as do those of bacteria. Yes indeed, bacteria do have immune systems – pretty complex ones at that. And like any useful immune system, the bacterial ones must have a good technique for distinguishing “foreign” from “self.” You may even have heard of the bacterial immune…

Dr. Gabriele D’Uva is finishing up his postdoctoral research at the Weizmann Institute. Here is his account of three years of highly successful research on regenerating heart cells after injury. Among other things, it is the story of the way that different ideas from vastly different research areas can, over the dinner table or in…

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…
