Antibiotic Resistant Superbug Arrives In America A new superbug resistant to our antibiotic of last resort has shown up in the U.S. We look at the threat, and our dwindling antibiotic options. On Wednesday, May 26, 2016, U.S. military officials reported the first U.S. human case of bacteria resistant to an antibiotic used as a last resort drug. The 49-year-old woman has recovered from an infection of E. coli resistant to colistin. But officials fear that if the resistance spreads to other bacteria, the country may soon see germs impervious to all antibiotics. (Janice Carr/CDC via AP) Earthquake prediction Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated confidence limits but with sufficient precision that a warning can be issued. Of particular importance is the prediction of hazardous earthquakes likely to cause loss of life or damage to infrastructure. Earthquake prediction is sometimes distinguished from earthquake forecasting, which can be defined as the probabilistic assessment of general earthquake hazard, including the frequency and magnitude of damaging earthquakes in a given area over years or decades. It can be further distinguished from earthquake warning systems, which upon detection of an earthquake, provide a real-time warning to regions that might be affected. Earthquake prediction and significance
Cultural Pluralism and Universal Bioethical Standards about treatments. Although children are generally assumed as lacking the rationality and the freedom to express their will, the extent of such a group is different among cultures. Consequently, different are situations in which adults can (or shall) express their will and choose what they consider the best interest for the child. Furthermore, the understanding of the human body and of its value is highly different among cultures. Western societies, and contemporary charters of rights, start from an individualistic point of view, according to which bodies are personal belongings, partially or fully available for the one who owns them.
Cell Size and Scale Some cells are visible to the unaided eye The smallest objects that the unaided human eye can see are about 0.1 mm long. That means that under the right conditions, you might be able to see an ameoba proteus, a human egg, and a paramecium without using magnification. A magnifying glass can help you to see them more clearly, but they will still look tiny. Book review: Never Let Me Go. : Adventures in Ethics and Science Last May, on my way back from a mini-conference in Stockholm, I had a long layover in Munich. Since major airports are now essentially shopping malls with parking for commercial jets, I used a little bit of that time to wander through a pretty impressive airport book store, where I picked up a copy of Never Let Me Go by Kazuo Ishiguro. I had heard a bit about it (maybe in reviews on the radio, if memory serves), and knew that it had some connection to ethical issues around biomedical technologies that seem not to be too far off from where we are now. Because I was taking a stab at using my layover time wisely, though, I spent the hours at the airport reading a couple of other books I had promised to review for journals.
Antibiotic Resistance Action Center The Antibiotic Resistance Action Center (ARAC) was created to reduce antibiotic resistance worldwide. ARAC, housed in the Milken Institute School of Public Health at the George Washington University, is led by microbiologist Dr. Lance Price, an internationally-recognized and respected scientist pioneering the use of genomic epidemiology to understand how the misuse of antibiotics in food animals affects public health. School of Mathematics and Physics Pictures above: (1) Longtime custodian of the famous experiment, the late Professor John Mainstone. (2) Three webcams trained on the experiment 24/7. (3) The Pitch Drop Experiment. (4) Close up of the pitch drop. About the Pitch Drop Experiment While the School of Mathematics and Physics at The University of Queensland has an international reputation for cutting-edge research and innovative teaching in the disciplines of Mathematics, Physics and Statistics, it is also home to the famous Pitch Drop Experiment. The experiment is listed in the Guinness Book of World Records as the world's longest-running laboratory experiment. The first Professor of Physics at UQ, Professor Thomas Parnell, began an experiment in 1927 to illustrate that everyday materials can exhibit quite surprising properties. The experiment demonstrates the fluidity and high viscosity of pitch, a derivative of tar once used for waterproofing boats.
An Image of God: The Catholic Struggle with Eugenics, Leon Robert P. George | Princeton University "If there is a story long overdue for telling, surely it is the story of how and why the Catholic Church and its faithful stood against the eugenics movement at a time when just about everyone else had gotten on the pro-eugenics bandwagon. In An Image of God, Sharon M. Leon tells the story and tells it exceptionally well. The book is worth reading not only for what it teaches us about the past, but also for the lessons it imparts at a time when eugenics ideologies are being revived and presented in new rhetorical garb." Tree of Life Web Project The Tree of Life Web Project (ToL) is a collaborative effort of biologists and nature enthusiasts from around the world. On more than 10,000 World Wide Web pages, the project provides information about biodiversity, the characteristics of different groups of organisms, and their evolutionary history (phylogeny). Each page contains information about a particular group, e.g., salamanders, segmented worms, phlox flowers, tyrannosaurs, euglenids, Heliconius butterflies, club fungi, or the vampire squid. ToL pages are linked one to another hierarchically, in the form of the evolutionary tree of life. Starting with the root of all Life on Earth and moving out along diverging branches to individual species, the structure of the ToL project thus illustrates the genetic connections between all living things.
Understanding Immunotherapy Immunotherapy, also called biologic therapy, is a type of cancer treatment designed to boost the body's natural defenses to fight the cancer. It uses substances either made by the body or in a laboratory to improve or restore immune system function. Immunotherapy may work in the following ways: Stopping or slowing the growth of cancer cellsStopping cancer from spreading to other parts of the bodyHelping the immune system work better at destroying cancer cells There are several types of immunotherapy, including: Improbable Research - Longest Running Experiments by Marc Abrahams We are happy to report that three of the world’s longest-running scientific experiments are indeed still running. It has been a number of years since anyone checked on all three. With assistance from scientists in several nations, we have managed to do so.
