On Wednesday, Nov. 12, the European Space Agency's Rosetta mission successfully landed on the surface of comet 67P/Churyumov-Gerasimenko. Descending at a speed of about 2 mph (3.2 kilometers per hour) the lander, called "Philae," first touched down and its signal was received at 8:03 a.m. PST (11:03 a.m. EST). 

Partially due to anchoring harpoons not firing, and the comet's low gravity (a hundred-thousand times less than that of Earth), Philae bounced off the surface and flew up to about six-tenths of a mile (1 kilometer) both above the comet's surface as well as downrange. At 9:53 a.m. PST (12:53 p.m. EST), almost two hours after first contact, Philae again touched down. A second, more modest bounce resulted, again sending it airborne. Philae's third contact with the comet's nucleus was the charm. At 10 a.m. PST (1 p.m. EST), the Rosetta mission's Philae lander became the first spacecraft to soft-land on a comet.

Two new international agreements will help to save migratory birds from hunting, trapping and poisoning, and to protect their long-distance flyways. A key objective is to phase out lead shot within three years, and eliminate the toxic drug diclofenac.

We know wildlife trafficking has become a huge problem for wild animals and imperiled species, but making it illegal is only part of the solution. Without the ability to identify wildlife products moving through ports, authorities have less power to stop the trade. The good news, according to a recent report published in the journal Biological Conservation, is that conservationists are successfully developing mobile apps to help authorities working around the world with the identification of wildlife that they believe are helping crack down on the problem.

The upcoming general elections in Greenland may see the country moving away from the idea of extracting and exploiting uranium, which the government voted in favour of just a year ago.

Uranium mining, the hottest topic in the the cold, Arctic country in recent years, was put on the agenda by former prime minister Aleqa Hammond in 2013, after 25 years with a 'zero tolerance' policy to mining of radioactive substances and oil drilling.

Roughly one-third of the U.S. population lives in the country’s 500,000 multifamily buildings, and they spend $22 billion on energy every year. Until this year, apartment and condo managers lacked the tools to measure how much energy they were wasting and compare their performance nationwide. Meanwhile, energy costs for renters have risen by 20 percent over the past decade.

 

Today, a new era of savings will be ushered in when the U.S EPA announces the first set of multifamily properties to earn the ENERGY STAR certification. The ENERGY STAR first became available to the sector this September, after a three-year partnership with Fannie Mae to develop the scoring system for multifamily properties.

The world is gaining weight and becoming less healthy, and global dietary choices are harming the environment, according to a new research report. Those are among the findings of a paper co-authored by David Tilman, a professor in the Bren School of Environmental Science & Management, and Michael Clark, a graduate student at the University of Minnesota, where Tilman is a professor. In “Global Diets Link Environmental Sustainability and Human Health,” published today in the journal Nature, the researchers find that rising incomes and urbanization around the world are driving a global dietary transition that is, in turn, diminishing the health of both people and the planet.
