Climate science: Trends in use of words in scientific studies may impact public perceptions

Climate change alone could lead to the extinction of wild Arabica coffee (Coffea arabica) well before the end of this century.

Why fish talk: Clownfish communication establishes status in social groups

Historically, the media have been particularly harsh to sharks, and it’s affecting their survival. A new study reviewed worldwide media coverage of sharks — and the majority isn’t good.

Small lethal tools have big implications for early modern human complexity

Posted: 07 Nov 2012 10:29 AM PST

On the south coast of South Africa, scientists have found evidence for an advanced stone age technology dated to 71,000 years ago at Pinnacle Point near Mossel Bay. When combined with other findings of advanced technologies and evidence for early symbolic behavior from this region, the research documents a persistent pattern of behavioral complexity that might signal modern humans evolved in this coastal location.

Giant pterosaur needed cliffs, downward-sloping runways to taxi, awkwardly take off into air

Quetzalcoatlus pushed the very boundaries of size to the brink, considered the largest flying animal yet to be discovered. Any larger, and it would have had to walk. But its bulk caused researchers to wonder how such a heavy animal with relatively flimsy wings became airborne.

New method could help communities plan for climate risk

Researchers have developed a new tool to help policymakers, city planners and others see the possible local effects of climate change.

Fossils and genes brought together to piece together evolutionary history

Scientists have reviewed recent studies that have used modern genetic techniques to shed light on fossils, and vice versa.

Synthetic biofilter removes estrogens from drinking water

Posted: 07 Nov 2012 09:27 AM PST

Conventional methods of filtering waste water in sewage treatment plants are unable to completely remove medicine residues such as the estrogens in birth control pills. These residues then find their way into rivers and lakes and also accumulate in our drinking water. For fish and other aquatic life, estrogens can lead to reproductive and developmental disorders and even to the formation of female characteristics in males. The potential long-term consequences for human beings — declining sperm counts, infertility, various cancers, and osteoporosis — are still largely unknown. Students have now identified enzymes from fungi growing on trees that can filter out medicine residues from sewage and drinking water.

Rising seas caused by glacial melting linked to Caribbean ‘extinction’ of bats

Most species loss in Bahamas and Greater Antilles have been explained by loss of land area.

Protected areas in East Africa may not be conserving iconic plants

A new study suggests protected areas in East Africa are not conserving plants such as the iconic Acacia tree.

The UV-absorbing net is an ally against pests

Posted: 07 Nov 2012 07:17 AM PST

Researchers have found that a reduction in the amount of UV light in the environment can reduce the propagation and aphid population density what involves an overuse decline of pesticides.

Geologist calls for advances in restoration sedimentology to protect world’s river deltas
