There is a limit to adapting to heat: Israel needs to re-prepare for a hotter, more humid summer

  • No comments
Physiological studies show that the human body's ability to dissipate heat is already limited in milder conditions than previously assumed. Another Israeli study found that during summer days, an increase from 27 to 32 degrees was associated with

Not just if you walk, but how: The study that tries to reduce falls after stroke

  • No comments
Dr. Shirley Handelsaltz of Ben-Gurion University is researching how people who have had a stroke control the natural variability of walking, and why subtle disruptions in this control may increase the risk of falls.

Weizmann scientists discovered hundreds of molecules that accelerate nerve regeneration – including in the brain

The study, published in the journal Cell, reveals a new role for rare RNA molecules that help peripheral nerves and even encourage the regrowth of nerve cells in the brain. A breakthrough in the treatment of degenerative diseases and rehabilitation from injuries

Oral bacteria linked to increased risk of stroke

  • One response
The lead researcher from the National Heart Disease Center in Osaka, notes: "In the future, if a rapid test is developed to identify harmful bacteria in the mouth and intestines, we could use this information to calculate stroke risk."
How a conventional MRI (left) and the home device (right) work

A home MRI scanner may revolutionize medicine

In ten years, it may be possible to find ambulances - or hospitals on wheels - that can reach multi-casualty incidents and provide the doctor in the field with a clear 3D image of each injured person. Doctors will no longer be needed

Heat stress in the summer in Israel increases the risk of stroke, especially a week after its occurrence

"Previous studies have shown a connection between temperature and the occurrence of various diseases. In a stroke, apparently, the heat causes a low fluid balance, which leads to changes in the brain, including the expansion of blood vessels, a decrease in blood volume

This is how the body sets up a unique emergency team against stroke using RNA-guide fragments

Guide RNA fragments, which until recently were known as stages of breakdown of the guide RNA on the way to their elimination from the body, were discovered in a new study led by Prof. Hermona Sorek from the Hebrew University, as molecules of great importance for preventing the collapse of the immune system following
