Four new mammal species discovered in Democratic Republic of Congo

Four new mammal species discovered in Democratic Republic of Congo

Julian Kerbis Peterhans, a Roosevelt University professor and adjunct curator at The Field Museum who has conducted extensive studies on mammals in Africa, has announced the discovery of four new species of small mammals in the eastern section of the Democratic Republic of Congo. The mammals were found during an expedition to the Misotshi-Kabogo highlands […]

Species diversity in coral reefs: Very similar looking coral species differ in how they survive in harsh environments

Species diversity in coral reefs: Very similar looking coral species differ in how they survive in harsh environments

Rising water temperatures due to climate change are putting coral reefs in jeopardy, but a surprising discovery by a team of marine biologists suggests that very similar looking coral species differ in how they survive in harsh environments. «We’ve found that previously unrecognized species diversity was hiding some corals’ ability to respond to climate change,» […]

Химическое оружие Сирии будет сброшено в Средиземное море

Химическое оружие Сирии будет сброшено в Средиземное море

Как недавно заявила Организация по запрету химического оружия (OPCW), до конца декабря 2013 года Сирия уничтожит 800 тонн химического оружия. Это, безусловно, хорошая новость. Плохой новостью является то, что побочные продукты процесса уничтожения этих боеприпасов будут сброшены в Средиземное море, где они имеют все шансы стать причиной гибели хрупких морских экосистем. Примечательно, что за настолько […]

Drought and climate change: an uncertain future?

Drought and climate change: an uncertain future?

Drought frequency may increase by more than 20% in some regions of the globe by the end of the 21st century, but it is difficult to be more precise as we don’t know yet how changes in climate will impact on the world’s rivers. The results come from a study, published in Proceedings of the […]

Tooth structure and wear provide clues to ecology and evolution of ancient marine creatures

Tooth structure and wear provide clues to ecology and evolution of ancient marine creatures

A trio of published studies have highlighted the importance of examining dental structure and wear in ancient creatures to better understand their ecology and evolution. New York Institute of Technology College of Osteopathic Medicine Assistant Professor Brian Beatty, Ph.D., contributed to all three of the studies with his expertise in analyzing patterns of tooth wear […]

Problemele de mediu cu care s-a confruntat Chevron in lume

Problemele de mediu cu care s-a confruntat Chevron in lume

    Compania Chevron a fost implicata, de-a lungul anilor, in mai multe procese in statele unde opereaza, printre care Bangladesh si Ecuador. Mai aproape, in Polonia, Chevron a anuntat recent ca a intentat un proces protestatarilor care nu au permis companiei accesul pe terenul unde urmeaza sa fie instalata prima sonda de explorare a […]

Spiders are partial to a side order of pollen with their flies

Spiders are partial to a side order of pollen with their flies

Spiders may not be the pure predators we generally believe, after a study found that some make up a quarter of their diet by eating pollen. Dr Dirk Sanders of the University of Exeter demonstrated that orb web spiders — like the common garden variety — choose to eat pollen even when insects are available. […]

Nitrogen deposition poses threat to diversity of Europe’s forest vegetation

Nitrogen deposition poses threat to diversity of Europe’s forest vegetation

Unless nitrogen emissions are curbed, the diversity of plant communities in Europe’s forests will decrease. Atmospheric nitrogen deposition has already changed the number and richness of forest floor vegetation species in European forests over the last 20-30 years. In particular, the coverage of plant species adapted to nutrient-poor conditions has reduced. However, levels of nitrogen […]

Research shows coral reefs worth saving

Research shows coral reefs worth saving

Although some scientists suggest that coral reefs are headed for certain doom, a new study by University of Florida and Caribbean researchers indicates even damaged reefs can recover. In a 13-year study in the Cayman Islands, warm ocean temperatures led to bleaching and infectious disease that reduced live coral cover by more than 40 percent […]

Denimite: новый композитный материал из старых переработанных джинсов

Denimite: новый композитный материал из старых переработанных джинсов

Как демонстрируют эксперименты и практика, композиционные материалы становятся прочнее и сильнее, в случае если в их состав добавляются волокна, в частности углеродные. Впрочем, не менее твердыми и прочными являются материалы, сделанные с использованием пластика, древесной массы и льняных волокон. А вот дизайнеры Джен Карлсон и Джош Шир разработали новый волокнистый композит, в который добавили измельченные […]
