Better educating physicians, using computers to order drugs and improving the system for policing inappropriate medication use can help reduce potentially deadly errors among cardiovascular patients, according to a new American Heart Association scientific statement published in todays Circulation: Journal of the American Heart Association.
Several reports have blamed medical errors for thousands of adverse events and deaths among patients in recent years. One study estimates that medical errors occur in 3.7 percent to 16.6 percent of hospitalized patients, contributing to at least 44,000 deaths in the United States each year. Data on deaths due to medical errors involving heart disease and stroke patients is more limited, but a small study of 182 deaths from cerebrovascular disease, pneumonia or heart attack suggests that 14 percent to 27 percent of the deaths may have been avoidable.
Additionally, a study of 203 cases of cardiac arrest concluded that about 7 percent of the arrests may have been prevented, says Jane E. Freedman, M.D., a member of the American Heart Associations Committee on Acute Cardiac Care and lead author of the statement. Medication error was the most common cause of potentially preventable arrest, occurring in 44 percent of cases. Mistakes can be made while prescribing, transcribing, dispensing, administering or monitoring medication. Sometimes the incorrect drug is prescribed or dispensed, while other times drug dosages are so high that they are toxic. Another error is creating a dangerous combination with other drugs.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
