CHICAGO — Rachel O’Conor booted up her slides and began posing questions to six older adults sitting around a table: How should primary care physicians support patients and caregivers after a diagnosis of dementia? And what stands in the way of getting adequate support? “Please speak louder and go slower,” suggested Susanne Smith, a 75-year-old […]Continue Reading ...
An international team of researchers, in which a female researcher from Universidad Politécnica de Madrid is involved, has identified one of the main causes of food allergy in the Mediterranean area. Recently, a research team led by Dr. Araceli Díaz Perales from Centre for Plant Biotechnology and Genomics (CBGP, UPM-INIA), in collaboration with other international […]Continue Reading ...
Lensless microscopy with X-rays, or coherent diffractive imaging, is a promising approach. It allows researchers to analyze complex three-dimensional structures, which frequently exist in nature, from a dynamic perspective. Whilst two-dimensional images can already be generated quickly and in an efficient manner, creating 3D images still presents a challenge. Generally, three-dimensional images of an object […]Continue Reading ...
Researchers from Bar-Ilan University have found that with pregnancy there is a change in the composition of gut bacteria in women. This could be associated with the changing hormonal status they speculate. The results of their study titled, “Progesterone Increases Bifidobacterium Relative Abundance during Late Pregnancy,” were published in the latest issue of the journal […]Continue Reading ...
Researchers at Karolinska Institutet in Sweden have developed a new method for identifying compounds that prevent aging. The method is based on a new way of determining age in cultured human cells and is reported in a study in the journal Cell Reports. Using the method, the researchers found a group of candidate substances that […]Continue Reading ...
What if the brain could detect its own disease? Researchers have been trying to create a material that “thinks” like the brain does, which would be more sensitive to early signs of neurological diseases such as Parkinson’s. Thinking is a long way off, but Purdue University and Argonne National Laboratory researchers have engineered a new […]Continue Reading ...
Researchers have identified ketamine-induced brain-related changes that are responsible for maintaining the remission of behaviors related to depression in mice — findings that may help researchers develop interventions that promote lasting remission of depression in humans. The study, funded by the National Institute of Mental Health (NIMH), part of the National Institutes of Health, appears […]Continue Reading ...
Scientists involved in a field campaign are away from their normal routines, offices and universities, including the support mechanisms available if sexual harassment or other inappropriate behaviors occur. Three Colorado State University researchers are examining the prevalence of sexual harassment in field-based research as part of a National Science Foundation-supported study. The CSU team, which […]Continue Reading ...
Engineering bacteria to intelligently sense and respond to disease states, from infections to cancer, has become a promising focus of synthetic biology. Rapid advances in genetic engineering tools have enabled researchers to “program” cells to perform various sophisticated tasks. For example, a network of genes can be wired together to form a genetic circuit in […]Continue Reading ...

In 1982, researchers reported a link between chronic gastritis and stomach bacterium Helicobacter pylori, triggering a flurry of research into this newly-identified pathogen. These studies made it clear that in addition to its involvement in gastritis, H. pylori was a significant factor in the development of both peptic ulcers and gastric cancer. But while the […]Continue Reading ...
Working with human colon cancer cells and mice, researchers led by experts at the Johns Hopkins Kimmel Cancer Center say they have successfully blocked the activity of portions of a protein known as UHRF1 and restored the function of hundreds of cancer-fighting genes that became “misregulated” by the disease. In a report on the research, […]Continue Reading ...

The results of the study, led by researchers from the National Institute for Physiological Sciences in Japan, will be published in […]Continue Reading ...
Biomedical engineers at Duke University have developed an automated process that can trace the shapes of active neurons as accurately as human researchers can, but in a fraction of the time. This new technique, based on using artificial intelligence to interpret video images, addresses a critical roadblock in neuron analysis, allowing researchers to rapidly gather […]Continue Reading ...
Soil contamination has long been recognized as a contributor to lead exposure in people and is now a health concern worldwide. In a new study, researchers sought to estimate the causal effects of exposure to lead in topsoil on the cognitive ability of 5-year-olds in the United States. The study found that higher lead in […]Continue Reading ...
