On the other hand

In Israel, the long summer school vacation is about to commence. Most students will be taking a rest from their studies and concentrating instead on relaxing in the sun.

In contrast, Israel’s researchers and innovators are working nonstop to improve lives everywhere.


Researchers have developed a hot-glue gun to adhere torn human tissues together.

Most serious injuries are currently treated with staples and stitches that have many drawbacks. They are painful, leave scars, require high skill from the doctor, and sometimes have to be removed after the tissues heal.

Medical glue, on the other hand, can produce improved medical and cosmetic results. The medical glues used today in dermatology and several other fields are very toxic and can be utilized only on the surface of the skin. In addition, hardening of the glue may make the organ less flexible or the adhesion may not be sufficiently strong.

With these limitations in mind, researchers have long been trying to develop nontoxic glue that is suitable for different tissues and flexible after hardening. Such a glue would also need to decompose in the body after the tissue is fused together.

The new approach is based on a biocompatible, low-melting-point, four‐armed N‐hydroxy succinimide‐modified polycaprolactone (star‐PCL‐NHS). Star‐PCL‐NHS is inserted into a hot-melt glue gun and melts upon minimal pressure, the team wrote.

Unlike the glue guns you can buy in crafts store, this glue is delivered by a special medical glue gun that warms the glue to a moderate temperature – just above that of the body – so as not to cause a burn.

After the glue is squeezed directly onto the wound it quickly hardens, bonding strongly with both edges of the wound. The dried glue decomposes within a few weeks, so nothing has to be removed.

The researchers say their novel adhesive – formulated by altering its molecular weight to control adhesive strength, melting point and elasticity — is four times as strong as existing medical adhesives and also can be used for gluing together torn tissue inside the body.


Seventy-four years ago the Holocaust had just been revealed in all its horrific detail and Jews worldwide were still battling to re-establish sovereignty in their historic homeland. Not a single person could ever have imagined that seven decades later a sovereign Jewish State would be selling advanced technology to the German Air Force.

Israel’s Elbit Systems announced this week that it won a contract worth almost $73 million from Diehl Defense GmbH & Co. to provide directed infrared countermeasure systems for the German Air Force’s Airbus A400M aircraft.

The contract will be performed over a four-year period.



 The Jerusalem Municipality has made touring the Old City for the visually impaired much more accessible.



Israel continues its mission of being “a light unto the nations.”

Watch how the country’s expertise in agricultural techniques is increasingly being shared with developing nations. This is truly a case of exporting knowledge and promoting goodwill.
