*A slight change in molecular structure introduced by genetic engineering gives crop-protecting proteins called Bt toxins a new edge in overcoming resistance of certain pests, a UA-led team of researchers reports in Nature Biotechnology.*

One of the most successful strategies in pest control is to endow crop plants with genes from the bacterium Bacillus thuringiensis, or Bt for short, which code for proteins that kill pests attempting to eat them.

But insect pests are evolving resistance to Bt toxins, which threatens the continued success of this approach. In the current issue of Nature Biotechnology, a research team led by UA Professor Bruce Tabashnik reports the discovery that a small modification of the toxins’ structure overcomes the defenses of some major pests that are resistant to the natural, unmodified Bt toxins.

When It Comes To Charitable Giving, People Respond To Their Immediate Emotions, Cu Study Says

When considering giving money to humanitarian crises people often donate in response to events that grab their immediate emotions, according to a recent study by researchers at the University of Colorado Boulder and Dresden University of Technology in Germany.

“The question we wanted to answer with our study is what is the impact of people’s emotions on their decisions to make charitable donations,” said CU-Boulder psychology Professor Leaf Van Boven, who co-authored the study. “We demonstrated that people act on what is immediately emotionally arousing to them. In other words, they respond to what makes them upset in the here and now.” (more…)

NASA Leads Study of Unprecedented Arctic Ozone Loss

PASADENA, Calif. – A NASA-led study has documented an unprecedented depletion of Earth’s protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in the stratosphere.

The study, published online Sunday, Oct. 2, in the journal Nature, finds the amount of ozone destroyed in the Arctic in 2011 was comparable to that seen in some years in the Antarctic, where an ozone “hole” has formed each spring since the mid-1980s. The stratospheric ozone layer, extending from about 10 to 20 miles (15 to 35 kilometers) above the surface, protects life on Earth from the sun’s harmful ultraviolet rays. (more…)

*HTC and Samsung Emerge as Top Android Device Manufacturers*

LONDON, UK, 13 September 2011 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service analysing growth trends of the smartphone platforms across the five leading European markets (France, Germany, Italy, Spain and the United Kingdom). In July 2011, nearly 1 in 4 smartphone users in EU5 reported using smartphones running on the Google Android platform. HTC had the highest market share among mobile original equipment manufacturers (OEMs), accounting for 34.6 percent of Android devices used across the region in this period, followed closely by Samsung with 31.7 percent of Android devices.

*Water significant limiting factor in growing crops like switchgrass*

Energy researchers and environmental advocates are excited about the prospect of gaining more efficient large-scale biofuel production by using large grasses like miscanthus or switchgrass rather than corn.

They have investigated yields, land use, economics and more, but one key factor of agriculture has been overlooked: water.

“While we are looking for solutions for energy through bioenergy crops, dependence on water gets ignored, and water can be a significant limiting factor,” said Praveen Kumar, an environmental engineer and atmospheric scientist at the University of Illinois at Urbana-Champaign. (more…)

LONDON, UK, 29th July, 2011 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service showing that 13.5 million users across the five leading European markets (France, Germany, Italy, Spain and the UK), accounting for 5.8 percent of all mobile subscribers, accessed online retail sites in the three month average period ending May 2011. In the EU5 region, the number of smartphone users accessing online retail sites has increased by 80 percent over the past year. This growth is even stronger in the UK, with a 163-percent increase in smartphone users accessing retail sites since May 2010. (more…)

Max Webster, an undergraduate who founded and directs Climate Voices, a Yale-based NGO working to publicize the human rights impacts of climate change, recently attended the U.N. Climate Change Conference in Bonn, Germany. He shared his experiences, frustrations and insights about the meeting and his own mission with the Yale Daily Bulletin.

Bonn, Germany is not a typical tourist destination. Unless you are paying a visit to the birthplace of Beethoven, you are likely to be there only to attend a meeting of one of the 17 United Nations’ institutions housed in the city’s official U.N. campus. (more…)

The earliest known image of an Egyptian ruler wearing the “White Crown” associated with Egyptian dynastic power has been brought to light by an international team of archaeologists led by Egyptologists from Yale University.

Carved around 3200 BCE, this unique record of a royal celebration at the dawn of the Egyptian dynastic period was found at a site discovered almost a half-century ago by Egyptologist Labib Habachi at Nag el-Hamdulab, on the West Bank of the Nile to the north of Aswan. (more…)
