Gecko (May 3 2015)
Description
The gecko is endowed with an impressive ability to scale walls and exceptionally smooth surfaces, thanks to the unique structure of millions of tiny hairs on its paws. This phenomenon is made possible by Van der Waals forces, which create a weak electrical attraction between the molecules of the hairs and the surface, providing the gecko with a firm grip.
Original title
שממית (3 במאי 2015)
השממית ניחנה ביכולת מרשימה לטפס על קירות ומשטחים חלקים במיוחד בזכות מבנה ייחודי של מיליוני שערות זעירות בכפות רגליה. תופעה זו מתאפשרת הודות לכוחות ואן-דר-ואלס, היוצרים משיכה חשמלית חלשה בין המולקולות של השערות למשטח ומעניקים לה אחיזה איתנה.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
