Meet 'photoswitches,' a breakthrough set of materials that act as their own batteries, absorbing energy and releasing it on demand.

The next big thing in solar energy could be microscopic.

Scientists at MIT and Harvard University have devised a way to store solar energy in molecules that can then be tapped to heat homes, water or used for cooking.

The best part: The molecules can store the heat forever and be endlessly re-used while emitting absolutely no greenhouse gases.

At least 58 people were killed and more than 100 others wounded in Thursday's attack on a UN base in South Sudan sheltering thousands of displaced civilians, a U.N. official said Friday.

“Forty-eight bodies, including children, women, men, have been recovered from inside the base. The bodies of 10 attackers have been found outside the base.

Wednesday was a historic day in Europe, where a new law will require its biggest companies to include sustainability factors as part of their annual financial report.

In a 599-55 vote, the European Parliament passed the law, which applies to publicly traded companies with more than 500 employees. They must address "policies, risks and results" in relation to "social, environmental and human rights impact, diversity and anti-corruption policies" in their annual reports.

In March 2014, the World Health Organization was notified of an outbreak of a communicable disease characterized by fever, severe diarrhea, vomiting, and a high fatality rate in Guinea. Virologic investigation identified Zaire ebolavirus (EBOV) as the causative agent. Full-length genome sequencing and phylogenetic analysis showed that EBOV from Guinea forms a separate clade in relationship to the known EBOV strains from the Democratic Republic of Congo and Gabon. Epidemiologic investigation linked the laboratory-confirmed cases with the presumed first fatality of the outbreak in December 2013. This study demonstrates the emergence of a new EBOV strain in Guinea.

WASHINGTON — The strain of Ebola virus that has killed 121 people in West Africa may have been circulating there undetected for some time, according to a new study. . .
 
. . . They confirmed that it is a member of the Zaire species, which kills most of its victims. Strains of that virus have caused outbreaks previously in Gabon and the Democratic Republic of Congo.
 
But this virus is a new strain, a previously unknown sister in the Zaire family.
 
Virologist Jens Kuhn at the National Institutes of Health said there may be more.

Introduction

The United Nations Framework Convention on Climate Change (UNFCCC) is an international treaty established in 1992 to cooperatively tackle climate change issues. The ultimate objective of the UNFCCC is to stabilize atmospheric greenhouse gas (GHG) concentrations at a level that would prevent dangerous interference with the climate system. Canada ratified the UNFCCC in December 1992, and the Convention came into force in March 1994. At the 15th session of the Conference of the Parties (COP15) to the UNFCCC in 2009, Canada signed the Copenhagen Accord, under which Canada has committed to reducing its GHG emissions to 17% below the 2005 level by the year 2020.^Footnote1

Escalating carbon dioxide emissions will cause fish to lose their fear of predators, potentially damaging the entire marine food chain, joint Australian and US research has found.

A study by the Australian Institute of Marine Science, James Cook University and the Georgia Institute of Technology found the behavior of fish would be “seriously affected” by greater exposure to CO2.

Researchers studied the behavior of coral reef fish at naturally occurring CO2 vents in Milne Bay, in eastern Papua New Guinea.

Statistical analysis rules out natural-warming hypothesis with more than 99 per cent certainty

An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth’s climate, according to a new study by McGill physics professor Shaun Lovejoy.

The study, published online on April 6, in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels. . .

. . . Lovejoy’s study applies statistical methodology to determine the probability that global warming since 1880 is due to natural variability. His conclusion: the natural-warming hypothesis may be ruled out “with confidence levels great than 99 per cent, and most likely greater than 99.9 per cent.”

A new, grid-tied offshore wave energy project called CETO is being readied off the west coast of Australia, near Perth. Carnegie Wave Energy is installing what is called the "first operating wave energy array scheme in the world." The installation will consist of three submerged buoys 11 meters (36 feet) in diameter, which will be anchored offshore. The buoys will create high pressure water which will be pumped to an onshore generating station to produce electricity.

In addition to producing power, the CETO technology incorporates an interesting synergy - it is also used to provide fresh water.

phys.org - April 11, 2014

Tap water in a Chinese city was found to contain excessive levels of the toxic chemical benzene, prompting residents to rush to buy bottled water, state media said on Friday.

Tests conducted on Thursday and Friday showed that tap water in Lanzhou, the capital of northwestern Gansu province, had as much as 200 micrograms of benzene per litre, 20 times the national limit, the official Xinhua news agency said, citing local environment authorities.

Benzene is an aromatic, colourless liquid and a basic raw material used in the petrochemical industry. Human exposure to the chemical increases the risk of cancer and other illnesses.

In a shocking display of indifference, senior United Nations Mission in South Sudan (UNMISS) officials have refused to improve living conditions for 21,000 displaced people living in a flood-prone part of a UN compound, exposed to waterborne diseases and potential epidemics. Despite repeated requests from humanitarian organisations, UNMISS is taking no actions in the camp to improve their chances of survival. Médecins Sans Frontières (MSF) today questions the UN’s commitment to meeting the needs of the war-torn country’s most vulnerable groups and calls for immediate action to save lives in Tomping camp.

Royal Dutch Shell, Adidas, Unilever, and some 70 other companies released a communiqué urging world governments to keep carbon emissions since the industrial revolution to a cumulative of 1 trillion metric tons. This is the emissions cap needed to keep warming below two degrees Celsius and avoid catastrophic impacts of climate change, according to the latest Intergovernmental Panel on Climate Change (IPCC) report, which for the first time calls for a trillion ton cap. We have already surpassed the halfway mark and are somewhere around 578,935,750,000 tonnes of carbon at the moment.
