Researchers at Johns Hopkins Bloomberg School of Public Health have demonstrated the use of stem-cell-derived 'mini-brains' to detect harmful side effects of a common drug on the developing brain. Mini-brains are miniature human brain models, developed with human cells and barely visible to the human eye, whose cellular mechanisms mimic those of the developing human brain.
In a first for quantum physics, University of Otago researchers have 'held' individual atoms in place and observed previously unseen complex atomic interactions.
Researchers at Northern Illinois University and the US Department of Energy's (DOE) National Renewable Energy Laboratory are reporting today (Feb. 19) in the journal Nature on a potential breakthrough in the development of hybrid perovskite solar cells. The scientists developed a technique to sequester the lead used to make perovskite solar cells and minimize potential toxic leakage.
Army researchers and industry partners recently published a study showing how they developed new materials and manufacturing methods to create higher performing helmet padding that reduces the likelihood of head injury in combat and recreational helmets.
Data and the economy stemming from them are the engine for the fourth industrial revolution. However, and according to Nikolaos Laoutaris, there is a very important leading player who currently receives absolutely nothing of the huge profits generated by the activity: the people who provide these data. Only in a very few cases do the humans producing data receive a measly compensation in kind for it: free online services.
Avoiding unnecessary bleeding during neuroendoscopic surgeries is crucial. When blood vessel location in a tumor cannot be visually confirmed, unintentional damage to the vessel and subsequent bleeding may occur. We propose a method for tumor blood vessel detection using a surgical robot system equipped with a force sensor in the gripper. Using this method, pulsation of a simulated artery inside a simulated tumor was detected by the force sensor, displayed as a gripping force wave.
Researchers at ETH have measured the timing of single writing events in a novel magnetic memory device with a resolution of less than 100 picoseconds. Their results are relevant for the next generation of main memories based on magnetism.
Technology lends a hand during tedious seed counting process.
University of Washington researchers have developed a mathematical model that describes how rotating detonation engines work.
A team of physicists at the University of Sussex has successfully developed the first nonlinear camera capable of capturing high-resolution images of the interior of solid objects using terahertz (THz) radiation.
