Дроны и войска поставлены на защиту кладок яиц морских черепах на мексиканских пляжах

Два небольших беспилотных аппарата парят над девственно чистым пляжем на тихоокеанском побережье Мексики, в то время как регулярные части войск военно-морского флота стоят на страже – их миссия заключается в предотвращении браконьерства яиц морских черепах, которые являются деликатесным лакомством в ресторанных меню. Каждый БПЛА оснащен шестью роторами, системой GPS и камерой, которая помогает отслеживать и […]

Endangered orangutans face a new threat

Endangered orangutans face a new threat

The loss of habitats is the greatest threat to the endangered orangutans, and now a new study says their existence could be further jeopardized if conservation efforts don’t include reintroducing these great apes into natural environments with enough high-energy food for them to survive. In the study, published on October 14 in PLOS ONE, Rutgers […]

Египетские ученые разработали экономичный способ для очистки соленой воды

Разработка новых, более быстрых и экономически рентабельных способов получения чистой питьевой воды является областью практически неограниченных возможностей и постоянных инноваций. Опреснение и процесс фильтрации морской воды являются, пожалуй, самыми известными и распространенными методами, но они не всегда оказываются эффективными и недорогими, чтобы ими можно было воспользоваться жителям развивающихся стран. Однако, недавно пришла обнадеживающая новость из […]
