On the eve of this year's Earth hour (March 25), researchers propose a solution in the journal Science for the global economy to rapidly reduce carbon emissions. The authors argue a carbon roadmap, driven by a simple rule of thumb or 'carbon law' of halving emissions every decade, could catalyze disruptive innovation.
Important findings have been revealed on the interaction between nutrient availability and the diversity of consumer species in freshwater environments. A better understanding of this interaction will contribute to developing possibilities to maintain biodiversity in all kinds of ecosystems.
A molecule found in car engine exhaust fumes that is thought to have contributed to the origin of life on Earth has made astronomers heavily underestimate the amount of stars that were forming in the early Universe, a study has found. That molecule is called polycyclic aromatic hydrocarbon. On Earth it is also found in coal and tar. In space, it is a component of dust.
Marine protected areas (MPAs) are an increasingly popular strategy for protecting marine biodiversity, but a new global study demonstrates that widespread lack of personnel and funds are preventing MPAs from reaching their full potential. Only 9 percent of MPAs reported having adequate staff.
The Arctic sea ice maximum extent and Antarctic minimum extent are both record lows this year. Combined, sea ice numbers are at their lowest point since satellites began to continuously measure sea ice in 1979.

Scientists have studied the development of the amphibian and reptile fauna in Western Siberia during the past twelve million years. In their study, they demonstrate that the species diversity of both groups of animals was noticeably higher in the past than it is today. Among others, for the first time the researchers discovered an Asiatic representative of the extinct frog family Palaeobatrachidae as well as evidence of a giant salamander with a length of up to 1.80 meters.
New archaeological analysis suggests people of Western Roman Empire switched between Hunnic nomadism and settled farming over a lifetime. Findings may be evidence of tribal encroachment that undermined Roman Empire during 5th century AD, contributing to its fall.
More than a century of theory about the evolutionary history of dinosaurs has been turned on its head following the publication of new research. The work suggests that the family groupings need to be rearranged, redefined and renamed and also that dinosaurs may have originated in the northern hemisphere rather than the southern, as current thinking goes.
Nearly 1,000 feet below the bed of the Dead Sea, scientists have found evidence that during past warm periods, the Mideast has suffered drought on scales never recorded by humans -- a possible warning for current times. Thick layers of crystalline salt show that rainfall plummeted to as little as a fifth of modern levels some 120,000 years ago, and again about 10,000 years ago.
Egyptologists have discovered rock art from the 4th millennium BC during an excavation at a necropolis near Aswan in Egypt. The paintings were engraved into the rock in the form of small dots and depict hunting scenes like those found in shamanic depictions. They may represent a link between the Neolithic period and Ancient Egyptian culture. The discovery earned the scientists the award for one of the current ten most important archeological discoveries in Egypt from the Minister of Antiquities in Cairo.
