Electrons spin. It's a fundamental part of their existence. Some spin “up” while others spin “down.” Scientists have known this for about a century, thanks to quantum physics.
They've also known that magnetic fields can affect the direction of an electron’s quantum spin, flipping it from up to down and vice versa. And it doesn't take much: Even a bacterial cell can do it.
Researchers at USC Dornsife College of Letters, Arts and Sciences and Israel's Weizmann Institute of Science have found that protein “wires” connecting a bacterial cell to a solid surface tend to transmit electrons with a particular spin.

Transplanting vaginal fluids from one woman to another could help tackle severe cases of a common bacterial condition, a study has suggested.
Bacterial vaginosis (BV) is thought to affect up to a third of women of reproductive age. It is caused when the balance of microbes in the vagina – known as the vaginal microbiome – becomes disturbed, with a drop in lactobacilli while other bacteria take over.

A trailblazing study by Israeli researchers suggests that intestinal microbes may have a direct effect on the course of amyotrophic lateral sclerosis (ALS), the incurable, fatal neurodegenerative disease also known as Lou Gehrig’s disease that affected physicist Stephen Hawking.
Published today in Nature, the study by researchers at the Weizmann Institute of Science revealed that the progression of an ALS-like disease in lab mice was slowed after the mice received certain strains of gut microbes or substances known to be secreted by these microbes.

When immune cells (macrophage, blue) meet bacteria (red), the first day or two is critical for the eventual outcome
REHOVOT, ISRAEL—July 22, 2019—First impressions are important – they can set the stage for the entire course of a relationship. The same is true for the impressions the cells of our immune system form when they first meet a new bacterium. Using this insight, Weizmann Institute of Science researchers have developed an algorithm that may predict the onset of diseases such as tuberculosis. The findings of this research were published in Nature Communications.

Non-communicable diseases including heart disease, cancer and lung disease are now the most common causes of death, accounting for 70 percent of deaths worldwide. These diseases are considered “non-communicable” because they are thought to be caused by a combination of genetic, lifestyle and environmental factors and can't be transmitted between people.
A new research paper in Science by a team of fellows in CIFAR's Humans and the Microbiome program throws this long-held belief into question by providing evidence that many diseases may be transmissible between people through microbes (including bacteria, fungi, and viruses) that live in and on our bodies.

The idea of ‘gut health’ barely existed a few years ago, but now, people in the UK spend around £750 million every year on probiotic products — ‘beneficial’ bacteria which is supposed to boost our health.
People take probiotics believing they increase levels of beneficial bacteria and will boost their immune system, digestion, mental health and more.
But last week, an expert warned that fermented foods such as sauerkraut — often consumed because of their probiotic effect — may trigger bloating, headaches and allergies.
Oct 24, 2019... Evogene Ltd. (Nasdaq: EVGN; TASE:EVGN) biopharmaceutical unit Biomica, which is developing innovative microbiome-based therapeutics, has announced a collaboration with the Weizmann Institute of Science to develop a selective treatment against antibiotic resistant strains of Staphylococcus aureus infection. This microbiome focused approach aims to target a specific microbe while maintaining the microbiome of the patients’ gut. The company has in-licensed Prof. Ada Yonath’s, Nobel Prize laureate, work and discoveries in high-resolution crystal structure of the large ribosomal subunit of the pathogenic Staphylococcus aureus. The crystal structure originates from pathogenic species, allowing a high degree of specificity, and together with Biomica’s unique computational technology, will enable the design and development of new types of selective, narrow spectrum antibiotics agents. Prof. Yonath’s group will scientifically support Biomica in the development of the technology.

Just as first impressions set the stage for the entire course of a relationship, first impressions set the stage for how the cells of our immune system react when meeting a new microbe, according to Israeli researchers at the Weizmann Institute of Science.
This new insight led the researchers to develop an algorithm that may predict the onset of such diseases as tuberculosis. Their findings were published July 22 in Nature Communications.

Gut bacteria may play a role in motor neurone disease ALS by speeding up progression, early studies reveal. The cruel condition that killed Professor Stephen Hawking, pictured
Gut bacteria could play a role in the development of motor neurone disease - also known as amyotrophic lateral sclerosis, early studies suggest.
Tests on mice showed a change in their gut microbe levels before symptoms of the crippling disorder appeared.

Walk into a health food store, or even a drugstore, and you’re likely to find an entire aisle, maybe two, dedicated to probiotics. Probiotics are live micro-organisms, usually bacteria, that provide health benefits when consumed at appropriate doses.
According to some surveys, approximately four million Americans take probiotics, which are available as pills, powders, foods and drinks. Probiotics are a huge industry — at least a $40 billion dollar one, according to Zion Market Research — and popular brands sell for 35 cents to $1 a dose, with a shelf life of several months.
