Is the best measure of a scientist's worth the total number of his or her published papers? For many years Institute for Scientific Information has been publishing the lists of impact factors providing quantitative tools for ranking scientists. The impact factor was devised by Eugene Garfield, the founder of the Institute for Scientific Information. Impact factors are calculated each year by the Institute for Scientific Information for those journals which it indexes, and are published in Journal Citation Reports. These measures apply only to journals, not individual articles or individual scientists. For the impact factor of individual scientists, there exists the h-index or Hirsch number. The Hirsch-index (h-index) has recently been defined by Hirsch as a new method for measuring the scientific activity. If a scientist has published n articles which all have been cited at least n times, then he will have a h-index of n . The h-index seeks to describe the impact of individual researchers, rather than journals. The h-index is the result of the balance between the number of publications and the number of citations per publication. H-index: Impact of Individual Scientists. H-index or/and impact factor - it is the question of the ...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Synthetic Genetic Array Analysis

Synthetic genetic arrays allow the systematic examination of genetic interactions. Here is the latest research focusing on synthetic genetic arrays and their analyses.

Congenital Hyperinsulinism

Congenital hyperinsulinism is caused by genetic mutations resulting in excess insulin secretion from beta cells of the pancreas. Here is the latest research.

Neural Activity: Imaging

Imaging of neural activity in vivo has developed rapidly recently with the advancement of fluorescence microscopy, including new applications using miniaturized microscopes (miniscopes). This feed follows the progress in this growing field.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Epigenetic Memory

Epigenetic memory refers to the heritable genetic changes that are not explained by the DNA sequence. Find the latest research on epigenetic memory here.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Femoral Neoplasms

Femoral Neoplasms are bone tumors that arise in the femur. Discover the latest research on femoral neoplasms here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
