WHO, CDC publish grim new Ebola projectionsSix months after the World Health Organization was notified of the Ebola outbreak in West Africa, its experts have released a new study warning that the situation is quickly growing worse and that Ebola may even “become endemic among the human population of West Africa, a prospect that has never previously been contemplated.”See all of Science’s coverage of the Ebola outbreak, including the Ebola vaccine, the U.N. Security Council’s historic resolution to confront the disease, and the situation on the ground in Liberia.Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)Half of Earth’s water formed before the sun was bornGood news for hunters of alien life: Water may be more widespread in planetary systems than we thought. New research shows that up to half of the water in our solar system formed before the sun itself was born. That means it’s likely that there is water everywhere waiting for planets to form.Fukushima radiation still poisoning insectsThe 2011 Fukushima nuclear disaster released massive amounts of radiation. Now, new research suggests that the environment in the Fukushima region, particularly in areas off-limits to humans, will remain dangerous for wildlife for some time.Anonymous peer-review comments may spark legal battleThe power of anonymous comments—and the liability of those who make them—is at the heart of a possible legal battle embroiling PubPeer, an online forum for anonymous, postpublication peer review. A researcher who claims that comments on PubPeer caused him to lose a tenured faculty job offer now intends to press legal charges against the person or people behind these posts—provided he can uncover their identities. Narwhal’s tusk may be its status symbolThe narwhal’s tusk is pretty iconic, but until now, we haven’t known what it’s actually for. Potential explanations have included its use in defense and breaking of sea ice. Now, new findings provide evidence that the tusk may indicate which males have the biggest testicles—and thus are the most fertile mates.’Space bubbles’ may have led to deadly battle in AfghanistanIn 2002, a rescue mission in Afghanistan went awry because a U.S. command post was unable to radio one of its helicopters about mistaken coordinates. What went wrong? Scientists say that turbulent space weather caused a communications blackout in the region and thus prevented the warning from getting to the rescue helicopter. The mission turned into a 17-hour firefight, costing seven lives.How did the ‘Berlin patient’ rid himself of HIV?Researchers are closer to unraveling the mystery of how Timothy Ray Brown, the only human cured of HIV, defeated the virus, according to a new study. Although the work doesn’t provide a definitive answer, it rules out the possibility that conditioning—the destruction of the body’s own immune system with chemotherapy and irradiation—can rid the body of HIV on its own.
