Bees and environmental stressors—canaries in the coal mine

Bee populations are declining worldwide, raising concerns of a "pollination crisis." Scientists have identified links to many human-induced environmental stressors, including pesticides, pollutants, parasites, diseases, and ...

World's reef fishes tussling with human overpopulation

In an unprecedented collaborative analysis published in the journal PLoS Biology, scientists from 49 nations demonstrated that the ability of reef fish systems to produce goods and services to humanity increases rapidly with ...

Selection drives functional evolution of large enzyme families

Researchers at Umeå University, together with researchers at the Institute of Botany, Chinese Academy of Sciences, show in a new study how natural selection drives functional evolution of a large protein family in conifer ...

Uncovering the underlying patterns in contemporary evolution

Wild populations must continuously adapt to environmental changes or risk extinction. For more than fifty years, scientists have described instances of "rapid evolution" in specific populations as their traits (phenotypes) ...

Path towards non-Si devices presented at IEDM 2012

At this week's IEEE International Electron Devices Meeting (IEDM 2012), imec addressed key challenges of scaling beyond silicon-channel finFETs. Imec showed that channel mobility can be boosted by growing non-Si channels ...

Global analysis shows soil ecosystems under stress

By statistically analyzing data from around the world, scientists have determined that multiple natural and human stressors are reducing levels of biodiversity and soil functioning in soil ecosystems. The number and specific ...
