Ua wehewehe ʻo Jose Centeno a me nā hoa hana ua hoʻokomo ʻia nā tungsten alloys i pani no ke alakaʻi i nā pōkā a me nā mea kaua ʻē aʻe.Ma muli o ka hopohopo e hiki ke hoʻopōʻino ke kēpau mai nā pōkā i hoʻopau ʻia i nā holoholona hihiu ke hoʻoheheʻe ʻia i loko o ka wai i loko o ka lepo, nā kahawai, a me nā loko.Ua manaʻo ka poʻe ʻepekema ʻo ka tungsten he mea ʻona ʻole, a he "'ōmaʻomaʻo" pani no ke kēpau.Ua manaʻo ʻia nā haʻawina hou, a me ka liʻiliʻi o ka tungsten i hoʻohana ʻia i kekahi mau pūhaka a me nā kuli, ua hoʻoholo ka hui o Centeno e hōʻiliʻili i nā ʻike hou aʻe e pili ana i ka tungsten.

Ua hoʻohui lākou i nā mea liʻiliʻi o kahi pūhui tungsten i ka wai inu o nā ʻiole laboratory, i hoʻohana ʻia ma ke ʻano he pani no nā poʻe ma ia noiʻi, a nānā i nā ʻāpana a me nā ʻiʻo e ʻike pono i kahi i pau ai ka tungsten.ʻO nā kiʻekiʻe kiʻekiʻe o ka tungsten aia i loko o ka spleen, kekahi o nā mea nui o ka ʻōnaehana immune, a me nā iwi, ʻo ke kikowaena a i ʻole ka "marrow" ʻo ia ke kumu mua o nā cell āpau o ka ʻōnaehana pale.ʻO ka noiʻi hou aʻe, ʻōlelo lākou, e pono e hoʻoholo i nā hopena, inā he, hiki i ka tungsten ke hana i ka ʻōnaehana pale.
