A new study from researchers at the University of Chicago has found that neuronal population dynamics in the motor cortex are very different during reaching and grasping behavior, challenging a popular theory that indicated intrinsic, dynamic patterns control motor behaviors.
New research into how catfish capture prey provides an unparalleled view of the internal mechanics of fish skulls and could inspire the design of new underwater robots.
Discussed in APL Bioengineering, researchers created a high-fidelity respiratory simulator that accurately represents the interplay between the abdomen, diaphragm, lungs and pleural space, the fluid-filled membrane surrounding the thorax and lungs. The model, using swine lungs, soft robotic materials and artificial muscles, allows precise tuning of pressure in each part of the system, so specific disease conditions can be tested. It also proved extremely useful for testing ventilator-only respiration by removing the elastomeric diaphragm.
Research on novel nanoelectronics devices led by the University of Southampton enabled brain neurons and artificial neurons to communicate with each other.
When our sun belches out a hot stream of charged particles in Earth’s general direction, it doesn’t just mess up communications satellites.
An experimental fingerprint detection approach can identify traces of cocaine on human skin, even after someone has washed their hands – and the test is also smart enough to tell whether an individual has actually consumed the class A drug, or simply handled it.
Elk have antlers. Rams have horns. In the animal kingdom, males develop specialized weapons for competition when winning a fight is critical. Humans do too, according to new research from the University of Utah. Males’ upper bodies are built for more powerful punches than females’, says the study, published in the Journal of Experimental Biology, suggesting that fighting may have long been a part of our evolutionary history.
Researchers at University of California San Diego have discovered that when certain microbes pair up, stunning floral patterns emerge.
