Thesuccessofanti-retroviral(抑止腫瘤病毒)drugsintreatingHIVisgettingresearchersatthe16thInternationalAIDSconferenceexcitedattheprospectthatthepotent(效力大的)medicinesmightbeexploitedtoperform.doubleduty.WhynotusethepoweroftheseARVstopreventanHIVtransmissionorinfectionfromtakingholdinthefirstplace?BillandMelindaGatesaskedthatprovocativequestionontheopeningdayoftheconference,andarecommit-tingtheirconsiderablefinancialresourcestowardfindingananswer.Intheirremarks,theyhighlightedtheneedtodevelopmicrobicides(殺菌劑)andoralpreventiondrugswhilewewaitforavaccine.AndtheywillgettheirfirsthintathowsmarttheirdecisionwasthisThursday,whenscientistsfromWestAfricareporttheinitialresultsfromthefirsttrialstudyinganoralpreventiondrug.

SohowrealisticaretheGatesinexpectingevenmorefromtheARVs?"Idothinktherangeofpreventionoptionswehavewithinthenextdecadewillgreatlyexpand,"saysDr.HeleneGayle,PresidentofCareUSAandco-chairoftheconference."Thebiologicplausibility(似乎有理)forbothmicrobicidesandoralpreventiondrugsissogreat."Dr.MarkDybul,U.S.GlobalAIDSCoordinator,saidthatifamicrobicideorpreventiondrugbecomesavailabletoprotectpeoplefrominfections,theywouldbefundedunderthePresident'sEmergencyPlanforAIDSReliefifcountrieschosetousethem."Wewouldsupportallofthat;itwouldbeperfectlywithinourmandatetodoallthat,"hetoldTIME.

ProblemswiththeFossilFuelEconomy

Whilefossilfuelshaveplayedanimportantroleingettingsocietytothepointitisattoday,therearefourbigproblemsthatfossilfuelscreate:

Airpollution—Whencarsburngasoline,theinternalcombustionenginealsoproduces:

-Carbonmonoxide,apoisonousgas

-Nitrogenoxides,themainsourceofurbansmog

-Unburnedhydrocarbons,themainsourceofurbanozone

Environmentalpollution—Theprocessoftransportingandstoringoilhasabigimpactontheenvironmentwheneversomethinggoeswrong.Anoilspill,pipelineexplosionorwellfirecancreateahugemess.

Globalwarming—Thecarbondioxidecomingoutofeverycar'stailpipeisagreenhousegasthatisslowlyraisingthetemperatureoftheplanet.Theultimateeffectsareunknown,butitisastrongpossibilitythat,eventually,therewillbedramaticclimatechangesthataffecteveryoneontheplanet.

AdvantagesoftheHydrogenEconomy

Thehydrogeneconomypromisestoeliminatealloftheproblemsthatthefossilfueleconomycreates.Therefore,theadvantagesofthehydrogeneconomyinclude:

Theeliminationofpollutioncausedbyfossilfuels—Whenhydrogenisusedinafuelcelltocreatepower,itisacompletelycleantechnology.Theonlybyproductiswater.Therearealsonoenvironmentaldangerslikeoilspillstoworryaboutwithhydrogen.

Theeliminationofgreenhousegases—Ifthehydrogencomesfromtheelectrolysisofwater,thenhydrogenaddsnogreenhousegasestotheenvironment.Thereisaperfectcycle—electrolysisproduceshydrogenfromwater,andthehydrogenrecombineswithoxygentocreatewaterandpowerinafuelcell.

Theeliminationofeconomicdependence—TheeliminationofoilmeansnodependenceontheMiddleEastanditsoilreserves.
