פרופ' ג'ואנה אייזנברג לומדת מהטבע כיצד יוכלו חומרי הבניין שלנו להגיב לשינויים בסביבה כדי לחסוך לנו אנרגיה, ואולי גם לרפא את עצמם מפציעות

המדענית שהופכת את החומר לחי ומגיב

צמח הכדנית הוא טורף ערמומי. רוב הזמן נמלים יכולות ללכת עליו בחופשיות, בלי שום סכנה. אבל כשהוא מתחיל להיות רעב זה כבר סיפור אחר. פתאום עלי הכותרת שלו חלקלקים במיוחד והנמלים המופתעות נותרות חסרות אונים, הן מחליקות מייד ללועו של הצמח הטורף, שם מיצי העיכול מזדרזים לעכל אותן. איך הכדנית עושה את זה? אולי גם אנחנו נוכל ללמוד ממנה משהו ולשדרג את החומרים והמוצרים שמשמשים אותנו?
