Metal ions regulate terpenoid metabolism in insects

Metal ions regulate terpenoid metabolism in insects

Max Planck scientists in Jena, Germany, have discovered an unusual regulation of enzymes that catalyze chain elongation in an important secondary metabolism, the terpenoid pathway. In the horseradish leaf beetle Phaedon cochleariae a single enzyme can trigger the production of two completely different substances depending on whether it is regulated by cobalt, manganese or magnesium […]

A new look at urbanization’s environmental impact

A new look at urbanization’s environmental impact

A research team from KTH Royal Institute of Technology has developed a technique for quick, simple and cost-effective mapping of worldwide urban growth and its environmental impact. Over the decade between 2000 and 2010, the population of New York City grew 4.8 percent while Shanghai’s increased by 65.6 percent. By 2030, the world’s urban population […]

Рекламный щит в Лиме генерирует питьевую воду для жителей

Рекламный щит в Лиме генерирует питьевую воду для жителей

В Лиме, столице Перу, недавно был установлен рекламный щит, созданный рекламным агентством Mayo DraftCFB в сотрудничестве с университетом техники и технологии (UTEC), который собирает капельки росы из воздуха и превращает их в питьевую воду для обитателей. Лима, которую также называют «мегаполисом среди пустыни» и в которой почти круглый год не бывает осадков, популярна проблемами с […]

Where the wild things go … when there’s nowhere else

Where the wild things go … when there’s nowhere else

Ecologists have evidence that some endangered primates and large cats faced with relentless human encroachment will seek sanctuary in the sultry thickets of mangrove and peat swamp forests. These harsh coastal biomes are characterized by thick vegetation — particularly clusters of salt-loving mangrove trees — and poor soil in the form of highly acidic peat, […]

Scurgeri la cel putin sase cuve de stocare de deseuri nucleare in Statele Unite

Scurgeri au fost detectate la cel putin sase rezervoare subterane de stocare de deseuri nucleare in statul Washington, ale carui autoritati au solicitat statului federal ajutor suplimentar in vederea curatirii locului, relateaza AFP. Guvernatorul acestui stat din nord-vestul Statelor Unite Jay Inslee a declarat ca amploarea scurgerilor la instalatia de depozitare de la Hanford, utilizata […]

Silver nanoparticles may adversely affect environment

Silver nanoparticles may adversely affect environment

In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms. Fifty days after scientists applied a single low dose of silver nanoparticles, the experimental environments produced about a third less biomass in some plants and microbes. […]

New marine species discovered in Pacific Ocean

New marine species discovered in Pacific Ocean

When Jim Thomas and his global team of researchers returned to the Madang Lagoon in Papua New Guinea, they discovered a treasure trove of new species unknown to science. This is especially relevant as the research team consisted of scientists who had conducted a previous survey in the 1990s. «In the Madang Lagoon, we went […]

Autoritatile se tem de un alt dezastru de mediu ca la “Autostrada Transilvania”

Autoritatile se tem de un alt dezastru de mediu ca la “Autostrada Transilvania”

Desi spun ca mai au putin pana la finalizarea lucrarii, constructorii autostrazii Deva – Orastie nu au inceput ecologizarea carierelor folosite pentru obtinerea materialului de umplutura pus in terasament. Un milion de metri cubi de material de umplutura au fost excavati in ultimii doi ani, din sase perimetre de pe raza judetului Hunedoara, pentru realizarea […]

Ship noise makes crabs get crabby

Ship noise makes crabs get crabby

A new study published in Biology Letters found that ship noise affects crab metabolism, with largest crabs faring worst, and found little evidence that crabs acclimatise to noise over time. The team from the Universities of Bristol and Exeter found that crabs exposed to recordings of ship noise showed an increase in metabolic rate, indicating […]
