What’s the Best Time of Day to Exercise, Morning or Evening?
What’s the Best Time of Day to Exercise, Morning or Evening?

https://www.weizmann-usa.org/news-media/in-the-news/what-s-the-best-time-of-day-to-exercise-morning-or-evening/

Jul 21, 2019... Some people are morning exercisers. For them, an early run or swim is as much a part of their wake-up ritual as that first cup of coffee. Others can’t abide the idea. They need a nighttime workout to rid themselves of the day’s stresses.
Does it make a difference? Several recent studies suggest that it does. But it’s complicated.
One recent paper indicates that morning exercise may activate certain genes in the muscle cells, boosting their ability to metabolize sugar and fat. While scientists say this finding requires further study, they think it ultimately might help those who are overweight or suffering from Type 2 diabetes.

Feb 07, 2020... We’re well into the New Year and many of us have resolved to get fit in 2020 … but does the time we work out make a difference? In the latest episode of Weizmann in Focus, Dave Doneson discusses the research of Dr. Gad Asher, who studies the effects of our biological clocks on everything from fitness to jetlag to liver disease.
Find out Dr. Asher’s take on whether mornings or evenings are the best time to hit the gym. Please share the video with friends via email or social media.

Is the Microbiome About to Change Medicine for Good?

https://www.weizmann-usa.org/news-media/in-the-news/is-the-microbiome-about-to-change-medicine-for-good/

Oct 15, 2019... Your body is composed of about 10 million human cells. It’s also home to about 100 trillion tiny microbes, mainly bacteria, that wield astonishing power over your health.
Many influences, from genetics, to diet and stress, contribute to the makeup of your microbiome — the collective community of microbes as personal as a fingerprint.
Understanding, manipulating and balancing the microbiome could play an increasing role in preventing and curing diseases.

Impaired Microbiota May Lead to Spondylarthritis
Impaired Microbiota May Lead to Spondylarthritis

https://www.weizmann-usa.org/news-media/in-the-news/impaired-microbiota-may-lead-to-spondylarthritis/

Apr 06, 2020... A comprehensive review of published studies on gut microbiota, immunity and arthritis suggests that having a microbial imbalance may precede the development of spondyloarthritides and osteoarthritis.
The review, which was published in Seminars in Arthritis and Rheumatism, suggests a close connection between an impaired microbiota, the immune system and inflammatory arthritis.
“In this review, we presented data supporting the idea that dysbiosis via a close, dynamic and tightly regulated cross talk with gut-associated lymphoid tissue, governs the development of inflammatory arthropathies, such as rheumatoid arthritis, spondyloarthritis and osteoarthritis. It became clear that unfavorable dysbiosis-mediated immune alterations precede the development of these disorders suggesting causal relationships in this link,” wrote authors Alexander Kalinkovich of the Weizmann Institute of Science in Israel, and Gregory Livshits of Tel Aviv University.

Cells Inside Cells: The Bacteria That Live in Cancer Cells
Cells Inside Cells: The Bacteria That Live in Cancer Cells

https://www.weizmann-usa.org/news-media/news-releases/cells-inside-cells-the-bacteria-that-live-in-cancer-cells/

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.

First Map of Tumour Microbiomes Finds Bacteria Live In Many Cancers
First Map of Tumour Microbiomes Finds Bacteria Live In Many Cancers

https://www.weizmann-usa.org/news-media/in-the-news/first-map-of-tumour-microbiomes-finds-bacteria-live-in-many-cancers/

May 28, 2020... 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.

Do Probiotics Actually Do Anything?
Do Probiotics Actually Do Anything?

https://www.weizmann-usa.org/news-media/in-the-news/do-probiotics-actually-do-anything/

Jun 28, 2020... There is an invisible universe hidden inside your body, it’s called the gut microbiome - a vast array of trillions of intestinal bacteria, hundreds of different species. They help digest your food in exchange for a warm, safe place to live. And we are only now starting to discover the gut microbiome plays a much larger role in our lives than we ever imagined.
Some of those bacteria found inside us are replicated in commercially manufactured mixtures called “probiotics.” You see them on grocery and pharmacy shelves, and they're recommended by your friends and often, by doctors like me.

Seasons of Our Hormones
Seasons of Our Hormones

https://www.weizmann-usa.org/news-media/news-releases/seasons-of-our-hormones/

Feb 02, 2021... REHOVOT, ISRAEL—February 2, 2021—Our minds may be affected by winter’s long nights or spring and its flowers, but what about our bodies? A new study at the Weizmann Institute of Science reveals that our hormones also follow a seasonal pattern. By analyzing data on several types of hormones from millions of blood tests, the researchers discovered that some hormones peak in winter or spring and others in summer. This research, which was published in the Proceedings of the National Academy of Sciences (PNAS), provides a broad, dynamic picture of hormone production – covering those connected to fertility, for example, but also hormones such as cortisol, which are mostly short-lived and not thought to be seasonal.

New Immune Players Involved in Metabolic Liver Disease
New Immune Players Involved in Metabolic Liver Disease

https://www.weizmann-usa.org/news-media/news-releases/new-immune-players-involved-in-metabolic-liver-disease/

May 19, 2021... REHOVOT, ISRAEL—May 19, 2021—Our livers work hard to perform a significant range of activities: helping us digest food, maintaining body temperature, and serving as an important checkpoint of the immune system for everything that we eat. It is inside the liver that the unique, rich, and complex network of immune cells and pathways is set up to decide whether a food particle is harmless or a dangerous pathogen that should be neutralized and removed. The liver is, therefore, very sensitive to the food we consume, and sometimes a poor diet can induce a serious dysregulation of the immune activities within it.
