7 Ukutholwa kwesayensi okungu-7 okungenzeka ukuthi uphuthelwe ngo-2017

1. Umdanso owodwa we-Black Hole Omnyama Wekhwalithi "

NgoJuni, iqembu elikhulu lezazi zezinkanyezi ezisebenza kanzima ekugcineni labona okuthile okwakukhona emisebenzini iminyaka engaphezu kwamashumi amabili - izimbobo ezinkulu ezijikeleza iminyaka engama-750 million ekhanyayo evela eMhlabeni. Kungumcimbi wethiyori okufanele wenzeke ngemuva kokuhlanganiswa kwemithala emibili, kepha kuze kube kulo nyaka, akekho noyedwa owayenobufakazi bawo owenzeka. Futhi manje siyakwenza.

2. Izilwane ezihamba kancane zingumnqobi omkhulu

Sesivele sazi ukuthi ama-tardigrades abonakala engabonakali, ebona ukuthi angasinda kanjani ekubeni efihlekile, ukushisa ngokweqile, ukubanda kakhulu, kanye ne-vacuum yesikhala. Futhi ucwaningo olushicilelwe kulo nyaka lusungula ukuthi ama-tardigrade angasinda cishe kunoma iyiphi i-apocalypse ephonswe kithi, noma ngabe umthelela we-gamma uqhume noma umthelela we-asteroid.

3. Impilo yomhlaba ingavela kuma-meteorites

Ucwaningo olwalufunda oluvela ku-Astrophysics ku-Chemistry kanye ne-geology lunikeze isisindo esithe xaxa ku-hypothesis ukuthi izithako zokuqala zokuphila ezimpilweni zethu zihambe lapha nge-Space. Leli qembu lithi njengamatshe esikhala afakwe amachibi afudumele, ahlelekile ebusweni basemhlabeni, ama-molecule ahlele ngendlela efanele yokukhiqiza ama-rna ama-polymers.

4. UThe Martian uzoba iqhwa

Ngo-Agasti, ososayensi beplanethi baveze okuthile okumangazayo ngamaphethini sezulu eMars - kuvela ukuthi phakathi nobusuku, kunezivunguvungu ezijulile zeqhwa ezenzeka emhlabeni, ngokuyisisekelo ziyikhanyisa ngama-chunks amancane eqhwa. Njengoba kunikezwe ukuthi kukhona amanzi amancane kangakanani, nakanjani asikulindele lokho.

5. Isidakamizwa esidala sekhulu sisebenze izimangaliso ze-autism

Lawa maseli 'e-virgin beta' avule izinzuzo ezintsha zososayensi abazama ukuqonda uhlobo lwesifo sikashukela, futhi basebenzela ukuza nezindlela ezintsha nezingcono zokwelapha.

7. Isazi semvelo siphuke imfumbe yezinyembezi "izinyembezi zikaRupert"

Amaconsi ePrince Rupert yilawa amaconsi axakayo angenziwa ngokudonsa ingilazi ebilinjisiwe emanzini. Ama-baubles aveziwe abunjiwe aqine kakhulu ekugcineni okuwugqinsi - ungabashaya ngesando noma udubule ngesibhamu, futhi ngeke baphule. Kepha konke okufanele ukwenze ukudonsa umsila we-droplet, futhi ngokuzumayo yonke le nto iqhuma. Cishe iminyaka engama-400, abacwaningi bebelokhu bezama ukuthola ukuthi kungani lokho kwenzeka. Futhi manje ekugcineni siyazi - yeka isikhathi sokuphila!

Ngaphezu kwalokho, uma unentshisekelo ephepheni lesikebhe lesikebhe e-EVA noma i - EVA SUP Pad & Eva Traction Pad , sicela ukhululeke ukuxhumana nathi.
