Everyone knows that how you say something can be as important as what you say. "Framing" is the science buzzword for 2007 and, as discussed in Do scientists need to 'frame' the debate for non-scientists? framing can be used for good or evil.

Both sides of the global warming debate accuse each other of framing and even some science sites persistently use framing to advance whatever agenda they are promoting. This has led to a great deal of discussion and research.

It's been recognized that most scientists are quite ethical in their research but discussions with non-experts is more of a grey area.

The Georgia Institute of Technology and Emory University have received a $1.5 million grant from the National Science Foundation to establish "The Origins Project," a center for integrated research, education and public outreach focused on the chemistry that may have led to the origin of life.

Scientists at the Weizmann Institute of Science and the University of California at Berkeley have now discovered that knowing the molecular structure of a substance can help predict whether we will find its smell pleasant or distasteful.

In sight and hearing our perceptions are determined by the physical properties of waves – the length of light waves in sight, and the frequency of sound waves in hearing - yet there was no known physical factor that could explain how our brains sense odors. The new study, conducted by Prof. Noam Sobel and his colleagues, represents a first step in understanding the physical laws that underlie our perception of smell.

For orthopaedic implants to be successful, bone must meld to the metal that these artificial hips, knees and shoulders are made of. A team of Brown University engineers, led by Thomas Webster, has discovered a new material that could significantly increase this success rate.

The team took titanium – the most popular implant material around – and chemically treated it and applied an electrical current to it. This process, called anodization, creates a pitted coating in the surface of the titanium. Webster and his team packed those pits with a cobalt catalyst and then ran the samples through a chemical process that involved heating them to a scorching 700° C.

Nearly 2 million children, or approximately 3 percent to 5 percent of young children in the United States, are considered to have ADHD. This disorder affects a child’s ability to focus, concentrate and control impulsive behavior. This disorder is so common that most school classrooms have at least one child with clinically-diagnosed ADHD.

In an 18-year-study on attention-deficit hyperactivity disorder (ADHD), Mayo Clinic researchers found that treatment with prescription stimulants is associated with improved long-term academic success of children with ADHD. The Mayo Clinic results are the first population-based data to show stimulant drug therapy helps improve long-term school outcomes.

A paper published this week in the open access journal PLoS Medicine provides strong evidence that one specific part of the genome is associated with rheumatoid arthritis.

Rene Toes and colleagues from Leiden University Medical Center, the Karolinska Institute, and Celera studied four groups of patients and matched controls. They found a consistent association with one specific region of the genome -- a region on chromosome 9 that includes the two genes, complement component 5 (C5) of the complement system (a primitive system within the body that is involved in the defense against foreign molecules) and a gene involved in the inflammatory response, TNF receptor-associated factor 1(TRAF1).
