18/06/2021Even the best face masks work only as well as their fit. And poorly fitting face masks greatly increase the risk of infection from airborne pathogens compared to custom-fitted masks, according to a new study by the University of Cincinnati.
18/06/2021Engineers at Duke University have demonstrated a prototype X-ray scanning machine that reveals not just the shape of an object but its molecular composition. With unprecedented resolution and accuracy, the technology could revolutionize a wide range of fields such as cancer surgery, pathology, drug inspection and geology.
17/06/2021Stereotactic systems are special devices used in neurosurgical procedures. Until now, conventional production methods have meant that these devices are not only expensive to manufacture, but are also geometrically limited.
17/06/2021Millions of people with diabetes are at risk of developing foot ulcers, which often lead to amputations and other health complications. Now, Scientists from the Centre for Biomechanics and Rehabilitation Technologies (CRBT) have developed a new method to reliably detect this risk without the need for complex electronic in-shoe sensors.
16/06/2021Gene expression patterns associated with pandemic viral infections provide a map to help define patients' immune responses, measure disease severity, predict outcomes and test therapies - for current and future pandemics.
16/06/2021Preliminary results of a new study show that a wearable electroencephalogram device that gathers data from the ear measures sleep as reliably as traditional EEG electrodes attached to the scalp.
15/06/2021Research teams from TU Darmstadt, British and US universities are focusing on one possible main process that leads to the death of brain cells – chemical reactions between different proteins in the brain and essential metals such as copper and iron – in their investigation of the causes and mechanisms of Alzheimer's disease.
15/06/2021Many modern fitness trackers and smartwatches feature integrated LEDs. The green light emitted, whether continuous or pulsed, penetrates the skin and can be used to measure the wearer's heart rate during physical activity or while at rest.
14/06/2021In eye surgery for cataract, the lens refilling method could allow to maintain or restore the lens's accommodation of the lens, i.e. the ability to adjust its refractive power flexibly. So far, however, this method has not yet been clinically successful.
14/06/2021In medicine, it is still standard practice to evaluate microscopy images of tissue sections by hand. This is used, for example, to assess how many cancer cells are in a lymph node.
