Too soon to harvest

first_imgToo Soon MonsoonWheatusOut 21 November”Who are Wheatus?” you might ask. Well, once upon a time (in fact, back in the days when GCSEs were still a worrying prospect) Wheatus briefly bothered the charts with the single Teenage Dirtbag. Don’t pretend you don’t remember it, because you know very well that the painful memory of that song will be with you forever. Ttragically, after reaching the dizzy heights of singles chart success with their debut offering, the story took a turn for the worse. The band’s profile rapidly declined, with the result that they were dropped by Sony-Columbia Records two years ago. Too Ssoon Monsoon, the group’s third album, was therefore entirely produced by lead singer and songwriter Brendan Brown and will be released through a small independent label.Not that Brown is bitter of course, what with developing a new range of “Suck Fony” merchandise and singing about corporate dominance. Those evil executives at the record companies get a very bad press generally, and there are plenty of examples of record bosses destroying artistic freedom and overlooking true musical genius. Fair play to them though, sometimes their judgements are spot on. The artistic freedom which Brown seems to have been demanding from his old label is the freedom to continue writing mediocre pop-rock and get paid for it, and now he has just that. Oh, and he whacks in the odd swear word, just to make it clear that he has, you know, strong feelings. Aall in all there is nothing offensively bad about Wwheatus’ music, it’s just unforgiveably bland. Ppropelled mostly by simple guitar riffs, the more upbeat songs are reasonable but instantly forgettable, such as the opener Something Good. But these louder songs do provide a good showcase for one of the bands’ main assets, their female backing singers. Eeasily the most irritating thing about is Brown’s nasal whine, and so the harmonies provided on the big choruses are a welcome relief. Iin fact Who Would Have Thought? is possibly the best song on the album, probably because it was written and sung by backing singer Katherine Froggatt without Brown’s intrusion.Regrettably, further attempts to expand the group’s sound have resulted in the appearance of some highly dodgy, Wwurlitzer-style organ effects, the main offender being The London Sun, which sounds like a Rrobbie Wwilliams song being spat out by a funfair.Brown’s songwriting does seem to approach genuine subtlety and emotionin its quieter moments, such as at the start of Hometown, a song about New York and the aftermath of Sseptember 11. But it is just too difficult to identify or sympathise with a voice that is so relentlessly annoying. Being a Wwheatus fan obviously requires a lot of hard work and dedication.Too Soon Monsoon will probably not be easy to find: it’s hard to imagine something this drenched in mediocrity album flying off the shelves without any press coverage or promotion. Hhowever, the band are threatening to tour sometime in the new year, so Wheatus fans will soon get their fix in person. Ssurely there must be some Wheatus fans left, mustn’t there?ARCHIVE: 6th week MT 2005last_img read more

Early land animals heard sounds with their lungs

first_imgWhen the first four-legged creatures emerged from the sea roughly 375 million years ago, the transition was anything but smooth. Not only did they have to adjust to the stress of gravity and the dry environment, but they also had to wait another 100 million years to evolve a fully functional ear. But two new studies show that these creatures weren’t deaf; instead, they may have used their lungs to help them hear.Fish hear easily underwater, as sound travels in a wave of vibration that freely passes into their inner ears. If you put a fish in air, however, the difference in the density of the air and tissue is so great that sound waves will mostly be reflected. The modern ear adapted by channeling sound waves onto an elastic membrane (the eardrum), causing it to vibrate. But without this adaptation, how did the first land animals hear?To answer this question, a team of Danish researchers looked at one of the closest living relatives of early land animals, the African lungfish (Protopterus annectens). As its name suggests, the lungfish is equipped with a pair of air-breathing lungs. But like the first animals to walk on land, it lacks a middle ear. The researchers wanted to determine if the fish could sense sound pressure waves underwater, so they filled a long metal tube with water and placed a loudspeaker at one end. They played sounds into the tube in a range of frequencies and carefully positioned the lungfish in areas of the tube where the sound pressure was high. Monitoring the brain stem and auditory nerve activity in the lungfish, the researchers were surprised to discover that the fish could detect pressure waves in frequencies above 200 Hz.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(*)The scientists hypothesized that the fish’s air-filled lungs might be responsible, because the air inside them buzzes and rattles in response to a propagating pressure wave. To confirm their hypothesis, however, they had to show that the air in the lungs vibrates in a frequency range that the fish’s auditory system could detect. Using x-ray imaging, they did just that, showing that the lungs of P. annectens resonated at about 300 Hz, matching the sensitivity of the lungfish’s hearing. The researchers also tested the hearing of lungfish in air, and to their surprise it turned out that the fish were not completely deaf, they report online this month in The Journal of Experimental Biology.In a second paper, published online today in the Proceedings of the Royal Society B, the same scientists looked at salamanders that have an ear configuration like those found in some of the early land animal fossils, thus allowing them to shed light on how the first four-legged animals may have heard. These animals’ ears are more like that of frogs, lacking an eardrum but having inner ear bones.The researchers repeated the lungfish experiments with the salamanders and found that they were able to detect sound pressure at frequencies higher than 120 Hz underwater. As with the lungfish, the salamanders’ lungs vibrated in a frequency range that they were able to hear. Despite having a fully functioning middle ear, these animals sensed sound pressure even better than their lungfish predecessors.This research demonstrates that early land animals “with no obvious adaptations for hearing nonetheless could pick up sound waves aided by an air bladder [such as a lung],” says Jennifer Clack, a paleontologist at the University of Cambridge in the United Kingdom, who was not involved with the work.Taken together, these results suggest that early terrestrial animals may have been able to hear sounds when they first stepped onto land, aiding by their newly formed lungs. “Lungs started to appear in fish underwater when they evolved air breathing in response to low oxygen levels in water 350 to 400 million years ago,” says study author Peter Madsen, a biologist at Aarhus University in Denmark. He says that any animal with air-filled lungs that vibrate in response to pressure waves “will hear pressure in water whether it wants to or not.” Further, the aerial hearing of lungfish and salamanders suggests the first land animals heard well enough in air to provide a functional steppingstone for the evolution of the middle ear.*Correction, 5 February, 9:16 a.m.: The image that appears with this article was originally identified as a lungfish.
