\u0218erpi: Mae\u0219trii mi\u0219c\u0103rii<\/h2>\n\n

V-a\u021bi \u00eentrebat vreodat\u0103 cum se t\u00e2r\u0103sc \u0219erpii pe p\u0103m\u00e2nt? \u00cen trecut, oamenii de \u0219tiin\u021b\u0103 credeau c\u0103 \u0219erpii se \u00eempingeau de pietre \u0219i crengi pentru a \u00eenainta. Totu\u0219i, un studiu recent a dezv\u0103luit c\u0103 secretul st\u0103 \u00een solzii lor. Solzii de pe abdomenul \u0219erpilor sunt orienta\u021bi \u00eentr-un astfel de mod \u00eenc\u00e2t se pot ag\u0103\u021ba de neregularit\u0103\u021bile din sol. \u00cemping\u00e2nd \u00een jos p\u0103r\u021bi din abdomenul lor pentru a profita de aceast\u0103 frecare, \u0219erpii pot genera suficient\u0103 for\u021b\u0103 de ridicare pentru a se propulsa \u00eenainte.<\/p>\n\n

Sistemul de avertizare al p\u0103s\u0103rilor<\/h2>\n\n

Gai\u021bele siberiene sunt cunoscute pentru strig\u0103tele lor puternice \u0219i ascu\u021bite. Cercet\u0103torii au descoperit c\u0103 aceste strig\u0103te nu sunt simple reac\u021bii de panic\u0103. De fapt, gai\u021bele siberiene folosesc peste 25 de strig\u0103te diferite, fiecare av\u00e2nd o semnifica\u021bie specific\u0103. Aceste strig\u0103te pot transmite informa\u021bii despre tipul de pr\u0103d\u0103tor din apropiere (\u0219oim sau bufni\u021b\u0103), nivelul de risc pe care \u00eel prezint\u0103 \u0219i dac\u0103 gai\u021bele din apropiere sunt \u00eenrudite.<\/p>\n\n

R\u0103d\u0103cinile de z\u0103pad\u0103: O adaptare unic\u0103 a plantelor<\/h2>\n\n

\u00cen Mun\u021bii Caucaz, oamenii de \u0219tiin\u021b\u0103 au descoperit un tip de structur\u0103 vegetal\u0103 necunoscut\u0103 anterior, numit\u0103 \u201er\u0103d\u0103cini de z\u0103pad\u0103\u201d. Aceste r\u0103d\u0103cini \u00ee\u0219i croiesc drum prin stratul de z\u0103pad\u0103, absorbind azotul prins \u00een z\u0103pad\u0103. Acest lucru le ofer\u0103 plantelor cu r\u0103d\u0103cini de z\u0103pad\u0103 un avantaj \u00een scurtul sezon de cre\u0219tere din mediul lor aspru.<\/p>\n\n

Originile r\u00e2sului<\/h2>\n\n

C\u00e2nd au \u00eenceput oamenii s\u0103 r\u00e2d\u0103? Pentru a afla, cercet\u0103torii au g\u00e2dilat oameni tineri, cimpanzei, bonobo, urangutani \u0219i gorile. Sunetele scoase de aceste maimu\u021be mari erau at\u00e2t de asem\u0103n\u0103toare \u00eenc\u00e2t studiul a concluzionat c\u0103 originile r\u00e2sului uman pot fi urm\u0103rite cu cel pu\u021bin 10 p\u00e2n\u0103 la 16 milioane de ani \u00een urm\u0103, p\u00e2n\u0103 la str\u0103mo\u0219ul nostru comun.<\/p>\n\n

Privirea vinovat\u0103 a c\u00e2inelui domestic<\/h2>\n\n

A\u021bi observat vreodat\u0103 c\u0103 atunci c\u00e2nd v\u0103 certa\u021bi c\u00e2inele, el v\u0103 arunc\u0103 o \u201eprivire vinovat\u0103\u201d? Potrivit unui studiu realizat de psihologul Alexandra Horowitz, aceast\u0103 privire nu este o reac\u021bie la ceea ce a f\u0103cut c\u00e2inele, ci mai degrab\u0103 la cearta st\u0103p\u00e2nului s\u0103u. C\u00e2inii arunc\u0103 o privire vinovat\u0103 chiar \u0219i atunci c\u00e2nd sunt complet nevinova\u021bi, ceea ce sugereaz\u0103 c\u0103 este mai degrab\u0103 un r\u0103spuns condi\u021bionat dec\u00e2t o indica\u021bie a vinov\u0103\u021biei.<\/p>","protected":false},"excerpt":{"rendered":"
