Jun 02, 2020... REHOVOT, ISRAEL—June 2, 2020—Cancer cells are comfy havens for bacteria. That conclusion arises from a rigorous study of over 1,000 tumor samples of different human cancers. The study, headed by researchers at the Weizmann Institute of Science, found bacteria living inside the cells of all the cancer types – from brain to bone to breast cancer – and even identified unique populations of bacteria residing in each type of cancer. The research suggests that understanding the relationship between a cancer cell and its “mini-microbiome” may help predict the potential effectiveness of certain treatments or may point, in the future, to ways of manipulating those bacteria to enhance the actions of anticancer treatments. The findings of this study were published in Science and featured on the cover.

The first comprehensive survey of the microorganisms that live inside tumours has found that bacteria reside in those from many different cancer types, but it is unclear whether they contribute to tumour growth.
These bacteria make up part of a tumour’s microbiome – the complex community of bacteria, fungi and other microbes that live inside it.
Bacteria have previously been found in tumours in the bowel and other tissues in the body that are routinely exposed to microbes. However, less is known about their presence in tumours from other cancers, like those of the bone, brain and ovary.

Jul 16, 2020... “Viruses can be ill-mannered guests,” says Dr. Noam Stern-Ginossar, “freely helping themselves to the host’s cell machinery and using it to make more viruses.”
Aug 14, 2020... REHOVOT, ISRAEL—August 14, 2020—Something like a quarter of the world’s population suffers from chronic pain at some point. As opposed to acute pain – for example, that feeling after hitting your finger with a hammer – chronic pain may not even have a clear cause, and it can linger for years or lifetimes. The burden of chronic pain includes damage to mental and physical health, lower productivity, and drug addiction. Now, a study led by researchers at the Weizmann Institute of Science suggests an original approach to treating this affliction by targeting a key gateway – one that leads to the activation of genes in the peripheral nerve cells that are involved in many forms of chronic pain. The findings of this study were published in Science.

Sep 09, 2020... REHOVOT, ISRAEL—September 9, 2020—“Contact tracing” inside infected cells is providing new clues into the workings of SARS-CoV-2, the virus that causes COVID-19. A research team at the Weizmann Institute of Science and the Israel Institute for Biological Research, in Ness Ziona, Israel, used the contacts between the virus’s genetic material and the cells’ protein-producing machinery to bring to light details of the viral protein-coding segments and the new – and potentially important – proteins they create. The findings of this research, published in Nature, could lead to better diagnostics or new treatments, and help to explain what makes this virus so skilled in the process of infection.
Sep 16, 2020... REHOVOT, ISRAEL—September 16, 2020—By tracking the evolution of what may be our oldest means of fighting off viral infection, a group at the Weizmann Institute of Science has uncovered a gold mine of antiviral substances that may lead to the development of highly effective antiviral drugs. These substances are made by virus-fighting enzymes known as viperins, which were previously known to exist only in mammals and have now been found in bacteria. The molecules produced by the bacterial viperins are currently undergoing testing against human viruses such as influenza and COVID-19. The study was published in Nature.

In February 2017, in Boston for the American Association for the Advancement of Science’s (AAAS’s) annual conference, The Curiosity Review snagged a chair in a packed ballroom of attendees.
The main attraction was Dr. Emmanuelle Charpentier. Then a rock star to scientists, today she is headline news; along with her longtime collaborator, Dr. Jennifer Doudna, Charpentier just received the 2020 Nobel Prize in Chemistry for the development of CRISPR. The method, which stands for “clustered regularly interspaced short palindromic repeats,” enables scientists to edit DNA.
Nov 05, 2020... REHOVOT, ISRAEL—November 5, 2020—Peculiar hybrid structures called retrons that are half RNA, half single-strand DNA are found in many species of bacteria. Since their discovery around 35 years ago, researchers have learned how to use retrons for producing single strands of DNA in the lab – yet despite extensive research into the matter, the retrons’ function in the bacteria was unknown. Now, in a paper published in Cell, Weizmann Institute of Science researchers report that the longstanding mystery has been solved: Retrons are immune system “guards” that ensure the survival of the bacterial colony when it is infected by viruses.
Dec 16, 2020... REHOVOT, ISRAEL—December 16, 2020—Cancers like melanoma are hard to treat, not least because they have a varied bag of tricks for defeating or evading treatments. Now, a combined research effort by the Weizmann Institute of Science, the Netherlands Cancer Institute in Amsterdam, and the University of Oslo shows exactly how tumors, in their fight to survive, will go so far as to starve themselves in order to keep the immune cells that would eradicate them from functioning. The work was published in Nature.

Prof. Maya Schuldiner of Weizmann’s Department of Molecular Genetics uses analogies to clarify the nature of cells. These tiny living beings are highly organized communities, and while there are different types – blood, skin, etc. – they have basically the same elements. One of these is the peroxisome, an organelle whose malfunction or absence can lead to devastating diseases in children.
Because cells are so similar, Prof. Schuldiner’s lab is able to use common Baker’s yeast as a stand in for the human cell to study peroxisomes. She hopes to someday offer treatment – even a cure – for the unique children suffering from peroxisomal diseases.
