People abuse #Imodium as an opiate substitute. It is dangerous and potentially deadly. Annals of Emergency Medicine. WASHINGTON --T he over-the-counter anti-diarrhea medication Imodium®, or its key ingredient loperamide, is increasingly being abused by people attempting to self-treat their opioid addiction, with sometime fatal results. Two case studies outlining the phenomenon were published online Friday in Annals of Emergency Medicine ("Loperamide Abuse Associated with Cardiac Dysrhythmia and Death").

In December 2015 an international group of scientists convened in Austria to discuss the imminent extinction of the northern white rhinoceros and the possibility of bringing the species back from brink of extinction. The discussions of this historic meeting appear in the international Journal Zoo Biology. The publication of this work is designed as part of the ongoing effort to raise awareness for the extinction crisis facing rhinos and many other species while also reaching out to the scientific community to share and gather information.

RNA polymerase II (Pol II), a key enzyme in our gene expression, is responsible for transcribing DNA into messenger RNA. Errors in transcription can cause deleterious effect upon repeated translation of erroneous mRNA into protein. Transcription infidelity may result in aging and human diseases such as cancer. During transcription, Pol II can detect the mis-incorporated RNA and backtrack to correct errors to ensure that each messenger RNA created will match with template DNA. However, it remains largely a mystery how Pol II controls the fidelity of gene transcription.

Autism and cancer share more than 40 risk genes, suggesting that common mechanisms underlying the functions of some of these genes could conceivably be leveraged to develop therapies not just for cancer but for autism as well, an extensive assessment by researchers with the UC Davis MIND Institute and Comprehensive Cancer Center has found.

These are microscope images showing two species of algae which swim using tiny appendages known as flagella. Long before there were fish swimming in the oceans, tiny microorganisms were using long slender appendages called cilia and flagella to navigate their watery habitats. Now, new research reveals that species of single-celled algae coordinate their flagella to achieve a remarkable diversity of swimming gaits.
