I-Oxygen-28 (28O), isotopu yomoya-mpilo enzima kakhulu engavamile itholwe abacwaningi base-Japan. Kungalindelekile kwatholakala ukuthi ngelesikhashana futhi alizinzile naphezu kokuhlangabezana nenani “lomlingo” lokunquma ukuzinza kwenuzi. Umoya-mpilo unama-isotopes amaningi; konke...
Ososayensi base-Lawrence Livermore National Laboratory (LLNL) bathole ukuthungela okuhlanganisiwe kanye nokuhlukana kwamandla. Ngomhla zi-5 kuZibandlela wezi-2022, ithimba locwaningo lenze ukuhlolwa kokuhlanganiswa okulawulwayo kusetshenziswa ama-lasers lapho imisebe ye-laser engu-192 iletha amajoule angaphezu kwezigidi ezingu-2 e-UV...
Ukubhekwa kwamasignali omsakazo angu-26 cm, okwakhiwa ngenxa yokuguqulwa kwe-hyperfine ye-cosmic hydrogen kunikeza elinye ithuluzi ocwaningweni lomkhathi wokuqala. Ngokuqondene nenkathi engathathi hlangothi yendawo yonke yosana lapho kungakhiphi ukukhanya, 26 cm...
Ukuhlolwa kwe-KATRIN okugunyazwe ukukala i-neutrinos kumemezele isilinganiso esinembe kakhudlwana somkhawulo ongaphezulu wesisindo sayo - ama-neutrino anesisindo esingama-0.8 eV, okungukuthi, ama-neutrino alula kuno-0.8 eV (1 eV = 1.782 x 10-36...
Abantu basendulo babecabanga ukuthi sakhiwe 'izakhi' ezine - amanzi, umhlaba, umlilo nomoya; esesazi manje ukuthi akuzona izakhi. Njengamanje, kunezici ezingaba ngu-118. Zonke izakhi zenziwe ngama-athomu ayekade...
Igagasi elidonsela phansi latholwa ngokuqondile okokuqala ngqa ngo-2015 ngemva kwekhulu leminyaka lokubikezela kwalo yi-Einstein's General Theory of Relativity ngo-1916. Kodwa, i-continuous, low frequency Gravitational-wave Background (GWB) okucatshangwa ukuthi ikhona kulo lonke. .
Abacwaningi e-Max Planck Institute for Nuclear Physics balinganise ngempumelelo ushintsho oluncane ngokungenakulinganiswa kwesisindo sama-athomu ngamanye kulandela ukweqa kwe-quantum kwama-electron ngaphakathi ngokusebenzisa ibhalansi ye-athomu ye-Pentatrap enembile kakhulu eSikhungweni sase-Heidelberg. E...
I-T2K, ukuhlola kwe-neutrino oscillation yesisekelo eside eside e-Japan, isanda kubika ukuqaphela lapho ithole khona ubufakazi obuqinile bomehluko phakathi kwezakhiwo eziyisisekelo ze-neutrinos kanye nalezo zozakwabo we-antimatter ohambisanayo, ama-anti-neutrino. Lokhu kubuka...
Ekuqaleni kwendawo yonke, ngokushesha ngemva kweBig Bang, 'indaba' kanye 'ne-antimatter' zombili zazikhona ngenani elilinganayo. Nokho, ngenxa yezizathu ezingaziwa kuze kube manje, 'indaba' ibusa indawo yonke yamanje. Abacwaningi be-T2K basanda kukhombisa...
Ososayensi bathuthukise izindlela zokuqomisana zezinto ze-interstellar futhi bakhombe izinhlamvu ezindala kakhulu ezaziwayo ze-silicon carbide emhlabeni. Lawa ma-stardust ane-pre-solar yobudala, akhiwa ngaphambi kokuzalwa kwelanga eminyakeni eyizigidi eziyizinkulungwane ezingu-4.6 edlule. I-meteorite, i-Murchison CM2 yawa...
Onjiniyela bakhe i-gyroscope encane kunazo zonke emhlabeni ekwazi ukuzwa ukukhanya engahlanganiswa kalula nobuchwepheshe besimanje obuphathekayo obuncane kakhulu. Ama-Gyroscopes ajwayelekile kubo bonke ubuchwepheshe esibusebenzisa ezikhathini zanamuhla. Ama-Gyroscopes asetshenziswa ezimotweni, kuma-drones nakumishini kagesi efana...
