Landfills and the introduction of nanomaterials in waste
Waste disposal on land (dumping) and landfilling remain the most prominent waste management techniques used __01__. The standards and practices for this type of waste disposal vary greatly ranging from uncontrolled sites to highly specialised and controlled engineered landfills. The potential __02__ of contaminants through landfill gas and leachate is largely dependent on landfill design, site conditions and the sophistication of the control measures in place, __03__ landfill gas recovery and leachate collection and treatment systems.
Modern engineered landfills use __04__ barriers, with few relying on natural barriers, to line the bottom of a landfill and incorporate collection systems for both leachate and landfill gas. The purpose of these collection systems is to capture and treat leachate and landfill gas; __05__ preventing the migration of leachate into ground/surface water and the release of untreated landfill gases to the atmosphere. An un-engineered landfill would be considered an uncontrolled system due to the lack of environmental controls, potentially resulting in significant environmental exposure of contaminants.
Because of widespread use of ENMs in a broad range of products, it is possible that some ENMs __06__ through landfill gases; however this report will primarily focus on ENMs that may be present in landfill leachate, as this is considered to be the primary means by which ENMs could be transported__07__ a landfill. Characterisation of landfill gases to identify the presence of ENMs __08__ an important area for further research.
Landfill leachate
is generated when rain passes through the waste mass and by the
liquid generated due to the breakdown of waste __09__ the landfill. The
composition of leachate is extremely __10__ depending on the type of waste
landfilled, the quantity of precipitation, the construction and operation
of the landfill, the age of the landfill and other factors such as
pH, temperature and microbial populations.

Could earth be fried by a 'superflare' from
the sun?
Daniel Clery
Solar flares on the sun frequently shower Earth with high-energy particles causing the Aurora Borealis and, occasionally, less-welcome disruptions to power networks and communications. But researchers say that there is a chance—though small—that the sun could one day blast us with a solar flare thousands of times as powerful, potentially frying our atmosphere and obliterating life.
Other stars
occasionally produce such “superflares,” some up to 10,000 times the power of
the largest solar flare ever detected. To see whether these are generated
by the same process as happens on the sun—the breaking and reconnection of
magnetic fields—astronomers studied light from 100,000 stars using China’s
Guo Shouiing Telescope. As they report online in Nature Communications,
superflares do seem to be produced by the same process, but they usually
occur in stars with much stronger magnetic fields than the sun’s. Still,
the researchers found that about 10% of the superflaring stars had
magnetic fields similar to or weaker than the sun’s. From evidence in tree
rings, the researchers say, it looks like Earth suffered small superflares—10
to 100 times bigger than normal—in 775 C.E. and 993 C.E. We can expect
more, they conclude, once per millennium. (As for the chances of an
Earth-frying flare, they don’t say.) So, back up your data and stock up on
candles.

Twelve years after the first Morse Code signal had been successfully transmitted across the Atlantic, an American inventor named Lee de Forest appeared in a US court charged with fraud. The case against him was that he had been selling shares in his Radio Telephone Company.
Putting his case before the jury, the prosecutor explained, 'De Forest has said in many newspapers and over his signature that it would be possible to transmit the human voice across the Atlantic before many years. Based on these absurd and deliberately misleading statements, the misguided public has been persuaded to purchase stocks in his company'.
Two years
later, the first direct transatlantic speech relay by radio telephone was made.
As for Lee de Forest, he patented more than 300 inventions and became
known in America as the ‘father of radio’.

High-tech eavesdropping on the ganges river
dolphin
Sonar signals hold clues that could save an endangered species
The Ganges river dolphin is one of only two remaining freshwater dolphin species on Earth. But pollution, fishing, and dams threaten to wipe it out entirely.
So acoustical engineer Harumi Sugimatsu and her team have deployed an experimental sonar monitoring system just under the surface of the murky water. The hope is to track the dolphins by the high-frequency clicks they use to navigate and hunt. By eavesdropping on their underwater lives, Sugimatsu believes she can gather data about their behavior and geographical range—data that conservationists can use in their struggle to keep the species from going extinct.

A rare genome has been identified in an ancient body pulled from a sarcophagus on a site near ancient Carthage, in a discovery which could throw new light on the history of human movement. The DNA of the 2,500-year-old remains of the ‘Young Man of Byrsa’, discovered in 1994 and believed to had been that of a young male Phoenician, was sequenced by a team of scientists. They found it contained an extremely rare type of genome sequence, known as U5b2c1, which is almost unknown among modern populations.
