Anterior cervical discectomy and fusion is widely used to treat spinal disorders. The fusion involves placing a bone graft or “cage” and/or implants where the surgically removed damaged disc was originally located to stabilize and strengthen the area. The risk factors for cage migration are multifactorial and include patient, radiological characteristics, surgical techniques and postoperative factors. A study is the first to evaluate the effect of the range of motion, cage migration and penetration using variable angle screws and cervical spine models. The plate developed and tested by the researchers provided directional stability and excellent fusion, showing promising clinical outcomes for patients with degenerative cervical spine disease.
Most simulations of our climate’s future may be overly sensitive to Arctic ice melt as a cause of abrupt changes in ocean circulation, according to new research led by scientists at the University of Wisconsin–Madison. Climate scientists count the Atlantic Meridional Overturning Circulation (or AMOC) among the biggest tipping points on the way to a planetary climate disaster.

A team used two DOE supercomputers to complete simulations of the full-power ITER fusion device and found that the component that removes exhaust heat from ITER may be more likely to maintain its integrity than was predicted by the current trend of fusion devices.
A restaurant outbreak in China was widely reported as strong evidence of airflow-induced transmission of COVID-19, but it lacked a detailed investigation about exactly how transmission occurred. In Physics of Fluids, researchers at the University of Minnesota report using advanced simulation methods to capture the complex flows that occur when the cold airflow from air conditioners interacts with the hot plume from a dining table and the transport of virus-loading particles within such flows.
With COVID-19 vaccines in reach, city officials, business administrators, and high-rise building managers are planning how to safely open offices as people come back to work. Columbia engineers have been exploring solutions to this problem, with real-world data and context provided by the Office of the Mayor of New York City. They used mathematical modeling and epidemiological principles to design interventions for queuing safely in elevators during a pandemic, without having to program any elevators.
Using the nation’s fastest supercomputer, Summit at Oak Ridge National Laboratory, a team of nuclear physicists developed a promising method for measuring quark interactions in hadrons and applied the method to simulations using quarks with close-to-physical masses.
With funding from the Coronavirus Aid, Relief and Economic Security (CARES) Act, Lawrence Livermore National Laboratory, chipmaker AMD and information technology company Supermicro have upgraded the supercomputing cluster Corona, providing additional resources to scientists for COVID-19 drug discovery and vaccine research
If CDC guidelines aren’t enough to convince you that face shields alone shouldn’t be used to stop the spread of COVID-19, then maybe a new visualization study will. Researchers simulated coughing and sneezing from a mannequin’s mouth using a laser light to visualize droplets expelled. They tested a plastic face shield and found that they block the initial forward motion of the exhaled jet, however, aerosolized droplets are able to move around the visor with relative ease.
Lawrence Livermore National Laboratory scientists have paired 3D-printed, living human brain vasculature with advanced computational flow simulations to better understand tumor cell attachment to blood vessels, the first step in secondary tumor formation during cancer metastasis.
Vanderbilt University Medical Center designed and rapidly deployed a curriculum specifically to equip nurses new to ECMO with the knowledge, skills and confidence necessary to provide proficient and safe care for patients receiving ECMO. The pre-COVID ECMO training proved to be an effective, resource-efficient and pragmatic solution that can be used across different types of ICUs and across institutions.
Combining high-fidelity computer simulations with ultra-high-speed X-ray imaging, researchers at Lawrence Livermore National Laboratory have discovered a strategy for reducing or even eliminating defects in parts built through a common, laser-based metal 3D-printing process.
Despite PPE use, reports show that many health care workers contracted COVID-19. A novel training technique reinforces the importance of using proper procedures to put on and take off PPE when caring for patients during the pandemic. Researchers vividly demonstrate how aerosol-generating procedures can lead to exposure of the contagion with improper PPE use. The most common error made by the health care workers was contaminating the face or forearms during PPE removal.
An interprofessional simulation-based educational program helped Mount Sinai Hospital train nearly 90% of its medical ICU staff to care for patients in prone position, as part of its 2018 implementation of a new protocol related to prone position ventilation for patients with acute respiratory distress syndrome.
Researchers are exploring the untapped potential of emerging smart cities to enable hyper-contextualized computational epidemiology to tackle COVID-19. The idea is to partner with the computational epidemiology community to integrate evidence-based models of COVID-19 transmission with hyper-local mobility data to provide place-specific forecasts of disease transmission. When these tools are integrated into city planning efforts, they will provide real-time insights into how mobility changes within the city affect the local population’s susceptibility to future outbreaks.
A device which simulates borehole ballooning, a detrimental side effect of deep-water drilling operations, is expected to ensure safe and efficient operations. If not prevented, borehole ballooning can lead to irreversible damage and serious drilling accidents, which can result in reservoir pollution and huge economic loss. In Review of Scientific Instruments, researchers present a device that can simulate this dangerous phenomenon in the hopes of preventing it.
A preliminary, flow visualization experiment suggests that staying 6 feet apart may not be sufficient. It only took the particles from the simulated cough a couple of seconds to travel 3 feet; in about 12 seconds it reached 6 feet and in about 41 seconds it reached around 9 feet. For a heavy cough, the particles can even travel up to 12 feet. In addition, a face mask doesn’t stop the particles 100 percent, but it does slow down the cough jets.
To assist in the COVID-19 research effort, Lawrence Livermore National Laboratory, Penguin Computing and AMD have reached an agreement to upgrade the Lab’s unclassified, Penguin Computing-built Corona high performance computing (HPC) cluster with an in-kind contribution of cutting-edge AMD Instinct™ accelerators, expected to nearly double the peak performance of the machine.
They say variety is the spice of life, and now new discoveries from Johns Hopkins researchers suggest that a certain elemental ‘variety’—sulfur—is indeed a ‘spice’ that can perhaps point to signs of life.

With seven reported cases in Florida to-date, FAU emergency medicine resident physicians prepared for the threat of a coronavirus contagion using a simulated or “mock” disaster scenario at FORTS Medical. The simulation involved a cruise ship dock-setting scenario and mock passengers were transported by bus. The passengers stormed into the large warehouse to challenge the resident physicians to react and respond quickly to triage the patients. About 100 people participated in the half-day simulation including local nurses, paramedics, and student and community actors.
