A 'carbon law' offers pathway to halve emissions every decade
Thu, 23 Mar 2017 14:13:38 EDT
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.
Strong interaction between herbivores and plants
Thu, 23 Mar 2017 10:57:22 EDT
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.
'Super sponge' promises effective toxic clean-up of lakes and more
Wed, 22 Mar 2017 11:09:44 EDT
Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem scientists have created a sponge that can absorb mercury from a polluted water source within seconds.
Cuantec: New force in the fight against food waste
Tue, 21 Mar 2017 12:39:08 EDT
CuanTec is a start-up company with a positive and practical solution to the disposal of seafood waste, which exacts a heavy cost, both financially and environmentally.
Heat exposure associated with mental illness
Tue, 21 Mar 2017 12:36:41 EDT
A mental hospital-based study in Hanoi, Vietnam looked at if there is a relationship between heat exposure and mental health problems. The results showed significant increase in hospital admissions for mental illnesses during periods of heatwaves, especially during longer periods of heat exposure.
Dead zones may threaten coral reefs worldwide
Tue, 21 Mar 2017 12:25:21 EDT
Dead zones affect dozens of coral reefs around the world and threaten hundreds more according to a new study. Watching a massive coral reef die-off on the Caribbean coast of Panama, they suspected it was caused by a dead zone -- a low-oxygen area that snuffs out marine life -- rather than by ocean warming or acidification.
Last remnant of North American ice sheet on track to vanish
Mon, 20 Mar 2017 14:38:56 EDT
The last piece of the ice sheet that once blanketed much of North America is doomed to disappear in the next several centuries, says a new study.
Warning of shortage of essential minerals for laptops, cell phones, wiring
Mon, 20 Mar 2017 11:00:42 EDT
Researchers say global resource governance and sharing of geoscience data is needed to address challenges facing future mineral supply. Specifically of concern are a range of technology minerals, which are an essential ingredient in everything from laptops and cell phones to hybrid or electric cars to solar panels and copper wiring for homes.
Engineering team develops novel nanofibre solution for clean, fresh air
Mon, 20 Mar 2017 08:55:01 EDT
A research team has successfully concocted a novel nanofiber solution that creates thin, see-through air filters that can remove up to 90 per cent of PM2.5 particles and achieve high air flow of 2.5 times better than conventional air filters. As an added bonus, this eco-friendly air filter improves natural lighting and visibility while blocking harmful ultraviolet (UV) rays.
Extensive ice cap once covered sub-Antarctic island of South Georgia
Fri, 17 Mar 2017 08:24:46 EDT
The sub-antarctic island of South Georgia -- famous for its wildlife -- was covered by a massive ice cap during the last ice age, new research indicates.
The carbon dioxide loop
Thu, 16 Mar 2017 14:11:33 EDT
Marine biologists quantify the carbon consumption of bacterioplankton to better understand the ocean carbon cycle.
Is spring getting longer? Lengthening 'vernal window'
Thu, 16 Mar 2017 12:56:28 EDT
When spring arrives, temperatures begin to rise, ice is melts, and the world around us starts to blossom. Scientists sometimes refer to this transition from winter to the growing season as the 'vernal window,' and a new study shows this window may be opening earlier and possibly for longer.
Multi-year study finds 'hotspots' of ammonia over world's major agricultural areas
Thu, 16 Mar 2017 11:21:29 EDT
Fertilizers, animal waste, changes to atmospheric chemistry and warming soils are all tied to increased ammonia over US, Europe, China and India, say researchers as they reveal the first global, long-term satellite study of airborne ammonia.
Scientists mobilize as bleaching resumes on Great Barrier Reef
Wed, 15 Mar 2017 14:38:21 EDT
Coral researchers are remobilizing to conduct aerial and underwater surveys along the Great Barrier Reef and elsewhere in Australia as coral bleaching reappears for the second year in a row. The decision coincides with the release today of a study in the journal Nature warning the Reef's resilience is rapidly waning.
Marine recovery after mass extinction was likely delayed by further biotic crises
Wed, 15 Mar 2017 14:06:49 EDT
Biotic crises during the Triassic period may have delayed marine recovery after a mass extinction during the late Permian, according to a new study.
