American researchers find large asteroid is rubble pile
Lunar regolith

Researcher team from the University of Tennessee, Knoxville, has found that near-Earth asteroid (29075) 1950 DA with a mean diameter of 1.1 km is held together by van der Waals forces between the fine grains of regolith similar to the material on the surface of the Moon. They show that the rotation rate is higher than could be possible in presence of gravity and friction alone, and cohesive forces prevent shedding and breakup of the asteroid. Their study "Cohesive forces prevent the rotational breakup of rubble-pile asteroid (29075) 1950DA" was published this Wednesday in Nature.

Australian government prepares legislation to restrict travel of Australian fighters overseas
Offence: travelling to places with active terrorism

On Tuesday, the Australian Cabinet approved the "Counter Terrorism Foreign Fighters Bill" which is to be introduced into the Australian Parliament between August 26 and September 4. The bill follows after the "National Security Legislation Amendment Bill" which was introduced into the Parliament on July 16 and is now before the Australian Senate. Attorney-General George Brandis mentioned at a joint press conference in Canberra on Tuesday, he has "been asked to develop — in consultation with relevant stakeholders, in particular, in the telecommunications sector — a system of mandatory data retention. That legislation has been approved in principle and is in development from today and is to be introduced into Parliament later in the year". As Tony Abbott mentioned, "the Government’s proposals to change 18C of the Racial Discrimination Act [...] are now off the table".

Australian–US team of scientists finds Atlantic warming causes Pacific climate trends
Recent Walker circulation strengthening and Pacific cooling amplified by Atlantic warming

Coauthor Malte Stuecker of the University of Hawaii Meteorology Department reports that "Our study documents that some of the largest tropical and subtropical climate trends of the past 20 years are all linked: Strengthening of the Pacific trade winds, acceleration of sea level rise [three times faster than the global average] in the western Pacific, eastern Pacific surface cooling, the global warming hiatus, and even the massive droughts in California". His colleague cauthor Fei-Fei Jin adds, "We are just starting to grasp the scope of the impacts of this global atmospheric reorganization and of the out-of phase temperature trends in the Atlantic and Pacific regions".

International team of scientists reports on Antarctic lead pollution
Industrial air pollution has persisted Antarctica since its arrival there in 1889 and remains significant in the current century

Concentrations of lead on the Antarctic continent have declined after the 1990s, but remain around three times higher than before industrialization, despite banning of leaded petrol and similar emissions regulations. As McConnell said, "Our measurements indicate that approximately 660 tonnes [1.5 million pounds] of industrial lead have been deposited on the snow-covered surface of Antarctic during the past 130 years [...] While recent contamination levels are lower, clearly detectable industrial contamination of the Antarctic continent persists today, so we still have a ways to go."

International team of scientists studies malaria drug resistance in Southeast Asia
Spread of Artemisinin Resistance in Malaria

The mutation considered in this study was identified last year as the molecular marker of artemisinin-resistant malaria. The current study found the mutation, located in the propeller domain of a Kelch protein on human chromosome 13, predicted when parasite clearance half-life would exceed five hours with 91.8% sensitivity and 88.4% specificity — usually correct in predicting both when long half-life would occur, and when it wouldn't. The study found a six-day treatment course effective against artemisinin-resistant malaria. Contribution: found in Eurekalert!, written text, with sources, links and categories.

Scientists analyse effects of global warming, atmospheric ozone on crops
Ozone–temperature covariation

Depending on region and crops, the yields may be primarily sensitive to ozone —in the case of wheat— or heat —in the case of maize— alone, providing a local estimation of relative benefits of climate change adaptation versus ozone regulation. The U.S. Department of Agriculture notes, "Ground-level ozone causes more damage to plants than all other air pollutants combined", highlighting the importance of air quality for agriculture. Results of NCLAN studies, published in a paper by AS Heagle in 1989, show dicot species, such as soybean, cotton, and peanut, lose more yield from ozone than do monocot species such as sorghum, field corn, and winter wheat. The researchers found that ozone pollution caused 46 percent of previously heat-attributed damage to soybean crops.

Researchers survey planet-sized space weather explosions at Venus
Three Venusian days (about two Earth years)

Space scientists located on three continents have published a survey of hot flow anomalies (HFAs) observed at the bow shock of Venus, in Journal of Geophysical Research on Tuesday. HFAs, discontinuities in the solar wind, were found to have much larger repercussions for Venus than for Earth. While the common HFA space weather phenomenon is deflected by the Earth's magnetosphere, Venus does not have such a reliable protection against the constant solar wind. Venus's ionosphere is generally in a sensitive balance with the outside pressure from the solar wind, and is regularly disrupted by the anomalies.

New South Wales government starts trial of hunting in national parks
Three-year-long trial of hunting in national parks of New South Wales, Australia

On Friday afternoon, amateur shooters were briefed about a three-year-long trial of hunting in national parks of New South Wales, Australia. The meeting was held in Griffith near Cocopara Nature Reserve, where the first shooting operation of the trial was to occur on Saturday, targeting the feral goats. The National Parks Wildlife Service (NPWS) has used aerial culls and baiting to reduce Cocoparra's goat population, but there are said to be thousands of goats at the reserve. The feral animals to be hunted in other reserves may include cats, deer, dogs, and pigs, beside goats — depending on the reserve.

Australian solar racing team parades at Sydney campus send-off
2013 World Solar Challenge

Australian solar racing team Sunswift paraded their fifth car, eVe, on the Kensington campus of the University of New South Wales, Sydney, yesterday. They are leaving for the 2013 World Solar Challenge this weekend. Both staff and students came to the send-off event in the early afternoon. eVe, the latest car built by the Sunswift team, was designed for the new Cruiser class of the competition, and thus meets regulations for normal roads-worthy vehicles. While its predecessor IVy weighed under 150 kg, eVe weighs approximately 300 kg, with light carbon fiber monocoque construction and 15 kWh batteries weighing only 63 kg. However, eVe has achieved a similar drag coefficient, despite different overall shape and larger frontal area. Contribution: original reporting, written a short text with many photographs, with sources, links and categories.
