26 aprilie 1986: are loc explozia nucleara de la Cernobil

La 26 aprilie 1986 are loc cel mai grav accident nuclear din istoria omenirii la centrala nucleara de la Cernobil, de langa Kiev, in Ucraina. Urmarile exacte ale dezastrului nu sunt cunoscute nici astazi, dar expertii cred ca in acea fatidica zi cateva mii de oameni au murit, iar peste 70.000 au suferit radiatii grave. […]

Scientists challenge FIFA: Save the 3-banded armadillo

Scientists challenge FIFA: Save the 3-banded armadillo

New research in Biotropica asks FIFA to follow through with its environmental claims. The 2014 FIFA (Fйdйration Internationale de Football Association) World Cup will be played in Brazil. Its «Football for the Planet» program aims to monitor greenhouse gasses, provide environmentally friendly stadiums, and better waste management. However, FIFA has not maximized this opportunity. In […]

Американская компания разработала туалетную бумагу из бамбука и отходов сахарного тростника

Американская компания разработала туалетную бумагу из бамбука и отходов сахарного тростника

Согласно оценкам социальных исследований, средний американец ежегодно использует около 23,6 рулонов туалетной бумаги. А если учесть, что для изготовления качественной белоснежной туалетной бумаги используется не вторсырье (макулатура), а целлюлоза, то можно представить себе величину ущерба, который наносят окружающей среде предприятия по производству этого нужного предмета личной гигиены. Но недавно на фестивале Долина музыки и искусства […]

Dead wood alive with management information in old-growth Iranian forest

Dead wood alive with management information in old-growth Iranian forest

Dead wood, such as old stumps and logs, is often overlooked when examining forest’s vitality; however, new research from old-growth forests in Iran point out the importance of this often-overlooked forest feature. In a new study, researchers sought to characterize the volume of coarse and fine woody debris present in old-growth beech forests in the […]

China si India, marile candidate ale catastrofei ecologice

China si India, marile candidate ale catastrofei ecologice

Dupa cum se stie, la sfarsitul lunii trecute, conform surselor de informare externe occidentale, in ultima noaptea de vineri spre sambata a lui martie, a avut loc la Paris intalnirea dintre prim-ministrul Rusiei si secretarul de stat al guvernului american. Nimeni nu a observat un lucru importnant: la discutii nu au fost prezenti tocmai cei […]

Crabs killing Northeast saltmarshes, study confirms

Crabs killing Northeast saltmarshes, study confirms

Ample new evidence has been provided that the reason coastal saltmarshes are dying from Long Island to Cape Cod is that hungry crabs, left unchecked by a lack of predators, are eating the cordgrass. Long-held beliefs that physical forces, rather than disrupted food webs, are killing the marshes just aren’t true, experts say. It’s a […]

How have changing sea-levels influenced evolution on the Galapagos Islands?

How have changing sea-levels influenced evolution on the Galapagos Islands?

The Galapagos Islands have an iconic status in the history of evolutionary study, now new research shows that the islands’ own geological past may have influenced the evolution of the chain’s native species. Writing in the Journal of Biogeography, Jason Ali and Jonathan Aitchison explore how fluctuating sea level changes over thousands of years impacted […]

100 kilometri de piste pentru biciclete in Capitala. Primaria are banii, dar nu s-a decis unde sa le amplaseze

100 kilometri de piste pentru biciclete in Capitala. Primaria are banii, dar nu s-a decis unde sa le amplaseze

Primaria Capitalei si Ministerul Mediului vor cheltui 10 milioane de euro pentru amenajarea a 100 de kilometri de piste de biciclete. Un proiect similar, in valoare tot de 10 milioane de euro, a fost realizat in anul 2012 si a avut ca urmare desfiintarea pistelor de catre Politia Rutiera, pentru ca erau periculoase. Acum, Sorin […]

Predator-prey made simple: Simplifying studies of predator-prey interactions and other ‘bistable’ systems

Predator-prey made simple: Simplifying studies of predator-prey interactions and other ‘bistable’ systems

Scientists have developed a way to dramatically reduce the complexity of modeling «bistable» systems which involve the interaction of two evolving species where one changes faster than the other (“slow-fast systems”). The work paves the way for easier computational simulations and predictions involving such systems, which are found in fields as diverse as chemistry, biology […]

Охлаждение дымовых газов может стать эффективным способом сокращения СО2 в атмосфере

Охлаждение дымовых газов может стать эффективным способом сокращения СО2 в атмосфере

В течение многих лет эксперты и инженеры всего мира изучали возможности различных способов улавливания и хранения углерода (CCS) – эти способа, хотя и являлись достаточно дорогостоящими, но считались важным шагом для сокращения выбросов СО2 и обороны окружающей среды. Но новое исследование, проведенное скандинавской исследовательской организацией SINTEF, демонстрирует, что система охлаждения дымовых газов может сократить расходы […]
