EPFL researchers have developed a method to observe the electrical activity of neurons by analyzing the behavior of surrounding water molecules. This simple and non-invasive method, which could eliminate the need for electrodes and fluorophores, can be used to monitor the activity within a single neuron or potentially on an entire region of the brain.
Rotator Cuff tears affect 15 percent of 60 year olds and carry a significant social and financial burden. Current operative techniques and repair adjuncts are associated with unacceptably high failure rates, stimulating investigation into novel tissue engineering and regenerative medicine (TERM) approaches in the field of rotator cuff surgery. In this review researchers explore the most recent advances in the field of electrospinning, focussing on proposed tissue-engineered solutions in tendon, specifically the rotator cuff.
Chondral defects caused by tumor, trauma, infection, congenital malformations are very common in clinical trials. It seriously affects the patient's physical function and quality of life. Through this review, the researchers aimed to review the progress of the types and preparation techniques of scaffold materials in cartilage tissue engineering.
A team of researchers has developed an algorithm for predicting the effect of an external electromagnetic field on the state of complex molecules. The new algorithm, presented in a paper in The Journal of Chemical Physics, enables researchers to look inside large polyatomic molecules, observe and potentially control electron motion therein.
While nearly all neighborhoods in Chicago benefited from reductions in homicide, relative inequality in crime between the city's safest and most dangerous neighborhoods actually increased by 10 percent over recent years, according to a new Northwestern University study.
A new study from Columbia Engineering and Columbia University Irving Medical Center shows that avoidant grievers unconsciously monitor and block the contents of their mind-wandering, a discovery that could lead to more effective psychiatric treatment for bereaved people. The researchers, who studied 29 bereaved subjects, are the first to show how this unconscious thought suppression occurs.
The remnants of Tropical Cyclone Owen have been lingering in the Southern Pacific Ocean for days. On Dec. 10, 2018 the storm finally appeared more organized on satellite imagery providing forecasters with a strong indication that it may be reborn as a tropical cyclone. NASA-NOAA's Suomi NPP satellite passed over the Gulf of Carpentaria and saw the storm.
Researchers at the Wyss Institute have created a novel 3D printing workflow that allows cardiologists to evaluate how different valve sizes will interact with each patient's unique anatomy, before the medical procedure is actually performed. This protocol uses CT scan data to produce physical models of individual patients' aortic valves, in addition to a 'sizer' device to determine the perfect replacement valve size.
Researchers at the National Institute of Standards and Technology (NIST) have developed a method for evaluating and selecting optimal antenna designs for future fifth-generation (5G) cellphones, other wireless devices and base stations.
A team of researchers developed a novel model of partial bladder outlet obstruction in female swine and used this model to show that even after inducing severe urinary outlet resistance and damage to the bladder, they could achieve significant improvements in bladder capacity through bladder reconstruction using acellular bi-layer silk fibroin grafts.
