Synthetic biology reveals mechanism of gene-overexpression to induce cell reprogramming

Temporal monostable system induced by gene-over expression can divide a cell population at basal state into two In iPS technology, gene overexpression of the four genes can induce reprogramming of a cell from differentiated state to stem cell state. However, the mechanism of reprogramming via gene-overexpression remains unclear in spite of the reproducibility of iPS […]

South American parrot in trouble: researchers

A vinaceous-breasted (Amazona vinacea) parrot rests on the branch of a tree in Curitiba, southern Brazil, on May 26, 2015 A South American parrot with a wine-colored chest is in deep trouble, with its population down to some 3,000 and a habitat reduced to a speck of what it once was, researchers said Tuesday. The […]

Fears for pink iguanas as Galapagos volcano erupts

The eruption of the volcano Wolf on Isabela Island, Galapagos on May 25, 2015 A volcano in the Galapagos islands erupted for the first time in more than 30 years Monday, sending streams of lava flowing down its slopes and potentially threatening the world’s only colony of pink iguanas. The Galapagos National Park warned on […]

Petrels tracked across the Oceans

  White chinned Petrel. Credit: Andy Wood, British Antarctic Survey Staff at British Antarctic Survey (BAS) are following the journeys of White-chinned Petrel fledglings as they make their first journeys over the South Atlantic Ocean in search of food. The birds have been fitted with small satellite transmitters and the location data are processed at […]

Соя может быть использована для очистки разливов сырой нефти

Соя может быть использована для очистки разливов сырой нефти

  Если вы изучали этикетки с компонентами на упаковке пищевых продуктов, вы, вероятно, заметили, что соевый лецитин содержится большом количестве продуктов, начиная от масла и заканчивая шоколадом. А не так давно ученые обнаружили еще один, потенциально эффективный способ использования этого вещества – для диспергирования разливов сырой нефти. Проведенное ими исследование показало, что соевый лецитин может […]

Cutting-edge tool helps predict impact of invasive species

Cutting-edge tool helps predict impact of invasive species

Researchers at the University of Waterloo have published results of a powerful new tool that could give ecologists new ways of tackling problems posed by deadly invasive species like Asian carp and Zebra mussels. Biology professors Heidi Swanson and Michael Power and Statistics and Actuarial Science professor Martin Lysy have created a new statistical tool […]

Rare glimpse into how coral procreates could aid future conservation

Rare glimpse into how coral procreates could aid future conservation

This is a pillar coral in lab, settled juvenile, which has never been seen before. Credit: Kristen Marhaver   A rare and threatened Caribbean coral species has for the first time been successfully bred and raised in the lab, according to research published in the open access journal BMC Ecology. The study provides the first […]

Credit: Tara Clemente, C-MORE/ UH SOEST   Researchers from the University of Hawaiʻi at Mānoa and colleagues found that microbial communities in different regions of the Pacific Ocean displayed strikingly similar daily rhythms in their metabolism despite […]

Супермаркеты будут отдавать нераспроданные продукты питания на благотворительность

Супермаркеты будут отдавать нераспроданные продукты питания на благотворительность

В рамках программы по решению двойной проблемы пищевых отходов и бедности, во Франции недавно принят новаторский закон, который обязывает крупные супермаркеты жертвовать непроданные продукты питания на благотворительность, к примеру, отдавать их на корм для животных. В противном случае на владельцев супермаркетов будет наложен штраф до 75 тысяч евро (в эквиваленте 82324 долларов США) и наказание […]
