Mobility model is closely linked to the city's characteristics

Wed, 2014-09-17 12:07
The massive use of motor vehicles leads to a whole host of problems, such as pollution, noise, accidents, occupation of space and others, which need to be tackled in two ways, according to the authors of new research: by improving the offer of public transport and properly managing the mobility demand.

Global shift away from cars would save US$100 trillion, eliminate 1,700 MT of CO2 pollution

Wed, 2014-09-17 07:33
More than $100 trillion in cumulative public and private spending, and 1,700 megatons of annual carbon dioxide -- a 40 percent reduction of urban passenger transport emissions -- could be eliminated by 2050 if the world expands public transportation, walking and cycling in cities, according to a new report.

Study on global carbon cycle may require reappraisal of climate events in Earth's history

Tue, 2014-09-16 13:25
A recent study of the global carbon cycle offers a new perspective of Earth's climate records through time. Scientists suggest that one of the current methods for interpreting ancient changes in the concentration of carbon dioxide in the atmosphere and oceans may need to be re-evaluated.

Exxon Valdez 2014: Does media coverage of humanmade disasters contribute to consumer complacency?

Tue, 2014-09-16 10:18
Twenty-five years ago, the Exxon Valdez spilled 11 million gallons of oil into Alaska’s Prince William Sound. Americans found themselves cleaning up another giant oil spill in the Gulf of Mexico in 2010. According to a new study, news coverage of environmental disasters serves to calm our immediate anxieties instead of catalyzing changes in the way fossil fuels are used.

New producer of crucial vitamin B12 discovered

Mon, 2014-09-15 16:52
A single group of microorganisms may be responsible for much of the world's vitamin B12 production in the oceans, with implications for the global carbon cycle and climate change, researchers have discovered. Thaumarchaeota, they say, are likely dominant vitamin B12 producers.

In a Season of Deadly Rains in India, Does the New Prime Minister Believe in Climate Change?

Mon, 2014-09-15 06:29
In the wake of devastating monsoon floods in northern India and Pakistan, Prime Minister Narendra Modi’s confusing comments on climate change are troubling.

Asian monsoon much older than previously thought

Sun, 2014-09-14 15:07
The Asian monsoon already existed 40 million years ago during a period of high atmospheric carbon dioxide and warmer temperatures, an international research team of geoscientists reports. Scientists thought the climate pattern known as the Asian monsoon began 22-25 million years ago as a result of the uplift of the Tibetan Plateau and the Himalaya Mountains.

Where's the atmosphere's self-cleaning power?

Tracking the atmosphere's cleanserDominant atmospheric “detergent” may be equally abundant in northern, southern hemispheres In a surprising finding, a research team concludes that the dominant "detergent" in the atmosphere is equally abundant in the northern and southern hemispheres.Yes

September 12, 2014 | In a finding that could alter how scientists quantify emissions of certain pollutants, a new study in Nature concludes that the self-cleaning power of the atmosphere does not differ substantially between the northern and southern hemispheres. The finding was surprising, as model simulations generally show that the hydroxyl molecule (OH)—the dominant “detergent” of the atmosphere that removes many pollutants by oxidizing them—is more common in the Northern Hemisphere.

15 years of carbon dioxide emissions on Earth mapped

Thu, 2014-09-11 15:18
Scientists have developed a new approach to estimate carbon dioxide emissions from burning fossil fuels -- one that provides crucial information to policymakers. Called the 'Fossil Fuel Data Assimilation System,' this system was used to quantify 15 years of carbon dioxide emissions, every hour, for the entire planet -- down to the city scale. Until now, scientists have estimated greenhouse gas emissions at courser scales or used less reliable techniques.

Ebola: Fast-tracking treatments

Thu, 2014-09-11 10:54

THE lucky ones are admitted to a health centre. They arrive bleeding, in taxis, on foot, in wheelbarrows and sometimes in ambulances. Mostly there is little help available and patients are dying alone, lying on the ground and lucky to receive even palliative care. Médecins Sans Frontières, a medical charity that has treated more than two-thirds of the known patients, says its centres are overwhelmed.The death toll from the Ebola virus is continuing to grow alarmingly. On September 9th the World Health Organisation (WHO) said it had recorded 4,293 cases in five west African countries, of which at least 2,296 people had died (see map below). But even the WHO’s experts believe that is an underestimate as many people are suspected to be dying at home. By some estimates 12,000 people have been infected with Ebola so far.In Liberia the disease is spreading quickly. The country’s existence is now “seriously threatened” as the functions of state are disrupted, Brownie Samukai, Liberia’s minister of national defence, said this week. The health system, already weak, is breaking down. At least 160 Liberian health-care workers have contracted the disease and half of them have...

Sex and back pain: Assume the position

Thu, 2014-09-11 10:54

PEOPLE with back pain are known for their grouchiness, and it is not helped if they are also starved for sex. Although sex makes serious demands on the spine, no one has taken the time to study how different sexual positions can accommodate different back problems.But Stuart McGill and Natalie Sidorkewicz of the University of Waterloo in Canada rose to the challenge. They brought ten heterosexual couples with healthy spines into the lab and asked them to have sex using five randomly assigned intercourse positions. These included two variations of the “missionary position”, where the man is on top of the woman and facing her; two variations of the “doggy” position, where the man is behind the woman on all-fours, and the “spoon”, which involves both participants lying cupped together on their sides. The last of these is often recommended by family doctors as the safest for sore backs.Most back problems in younger folk are triggered by bending forward, a movement called flexion. But as people age, reaching up and back, known as extension, becomes a more common cause. The researchers wanted to see how various sexual positions differentially taxed the spine, so people would know what to avoid.They used eight infra-red motion-capture cameras to track the movements of reflective dots placed strategically on the participants’ bodies. The cameras monitored the movements for 20...
