IBM scientists have been able to image the “anatomy” — or chemical structure — inside a molecule with unprecedented resolution, using a complex technique known as noncontact atomic force microscopy.

Addressing safety concerns related to potential gene therapies for Parkinson’s disease, researchers at the have constructed a gene transfer therapy that can be inhibited with a common antibiotic. Experiments in rats show that the gene therapy product can be completely shut off, indicating for the first time that genes that have been irrevocably delivered to [...]

It can strike anyone: rheumatism occurs just as often as diabetes, arteriosclerosis and cancer combined. Approximately one percent of the population is stricken with the rheumatoid arthritis. Now scientists in Germany have developed such an early detection method.

Even DNA is subject to attack by parasites — so-called transposons. Transposons are mobile genetic elements that can insert into genomes at variable sites and disseminate to new locations. Researchers have discovered a mechanism that helps to repress their activity.

A new study reveals that when it comes to pain control, the “placebo effect” involves evolutionarily old pain control pathways in the human brainstem, the part of the brain that is continuous with the spinal cord. The research provides fascinating mechanistic insight into how and why simply expecting that a treatment will reduce pain can [...]
A handwriting lie detection tool may change the face of effective law enforcement. Researchers utilized a computerized tablet that measured the physical properties of the subject’s handwriting, which are difficult to consciously control. They have found that these handwriting characteristics differ when an individual is in the process of writing deceptive sentences as opposed to [...]

A recent paper presents an algorithm that may be used to predict the future dynamics of plant communities, an increasingly interesting area of study as significant environmental changes, such as global climate change and invasive species, are affecting current plant communities. A goal of plant ecology has been to find ways to predict plant behavior [...]

With the epidemic of childhood obesity in the United States, there is concern that overweight and obese children need to be screened for chronic medical conditions, including high cholesterol levels. However, body fat is not an effective indicator of high cholesterol in children, according to new research.
