Приготовление крепких вин

Приготовление крепких вин

Для приготовления крепких вин, как портвейн, мадера, херес, токай и другие, собирают виноград сахаристостью 22 – 32% и кислотностью 5-7 г/л. Ягода раздавливают, отделяя гребни. Часто сусло настаивают на мезге, для придания вину большой полноты , экстрактивности, определенных вкусовых и ароматических свойств. После прессования и отстоя, сусло подвергают брожению. Когда количество сахара   достигает уровня примерно […]

Global study reveals new hotspots of fish biodiversity

Global study reveals new hotspots of fish biodiversity

Teeming with species, tropical coral reefs have been long thought to be the areas of greatest biodiversity for fishes and other marine life — and thus most deserving of resources for conservation. But a new global study of reef fishes reveals a surprise: when measured by factors other than the traditional species count — instead […]

Got calcium? Mineral is key to restoring acid rain-damaged forests

Got calcium? Mineral is key to restoring acid rain-damaged forests

Calcium can do much more than strengthen bones. The mineral is a critical nutrient for healthy tree growth, and new research shows that adding it to the soil helps reverse the decades-long decline of forests ailing from the effects of acid rain. The paper, published Sept. 19 in the journal Environmental Science and Technology (EST) […]

Are banana farms contaminating Costa Rica’s crocs?

Are banana farms contaminating Costa Rica’s crocs?

Shoppers spend over £10 billion on bananas annually and now this demand is being linked to the contamination of Central America’s crocodilians. New research, published in Environmental Toxicology and Chemistry, analyses blood samples from spectacled caiman in Costa Rica and finds that intensive pesticide use in plantations leads to contaminated species in protected conservation areas.

Южнокорейский город Сувон на месяц стал самым «зеленым» городом в мире

Южнокорейский город Сувон на месяц стал самым «зеленым» городом в мире

Представьте себе, что все машины в вашем городе просто забрали и заменили их экологически чистыми альтернативами. Жизнь без работающих на ископаемом топливе автомобилей может показаться сегодня чем-то на грани фантастики, однако, город Сувон в Южной Корее взял на себя обязательство на месяц превратить самый густонаселенный район Хаенгганг-донг в целиком пешеходную зону. Граждане, проживающие в этом […]

Overfishing of sharks is harming coral reefs, study suggests

Overfishing of sharks is harming coral reefs, study suggests

A team of scientists from Canada and Australia has discovered that a decline in shark populations is detrimental to coral reefs. «Where shark numbers are reduced due to commercial fishing, there is also a decrease in the herbivorous fishes which play a key role in promoting reef health,» said Jonathan Ruppert, a recent University of […]

Algorithm finds missing phytoplankton in Southern Ocean

Algorithm finds missing phytoplankton in Southern Ocean

NASA satellites may have missed more than 50% of the phytoplankton in the Southern Ocean, making it far more difficult to estimate the carbon capture potential of this vast area of sea. But now, new research published in the Journal of Geophysical Research, «Three improved satellite chlorophyll algorithms for the Southern Ocean,» has led to […]

Personality differences: in lean times red deer with dominant personalities pay a high price

Personality differences: in lean times red deer with dominant personalities pay a high price

Saving energy is important for humans and animals alike when resources are limited. Scientists at the Research Institute of Wildlife Ecology of the University of Veterinary Medicine, Vienna, found out that although higher-ranked red deer gain privileged access to patches of food, they also have higher metabolic rates and thus use more energy. This can […]

Environmental complexity promotes biodiversity

Environmental complexity promotes biodiversity

A new study published in the journal American Naturalist helps explain how spatial variation in natural environments helps spur evolution and give rise to biodiversity. The study, led by McGill University evolutionary biologist Ben Haller in collaboration with IIASA Evolution and Ecology Program Leader Ulf Dieckmann and IIASA researcher Rupert Mazzucco, suggests that a varied […]
