Study details first artificial intelligence tool to help labs rule-out COVID-19

Hospital-based laboratories and doctors at the front line of the COVID-19 pandemic might soon add artificial intelligence to their testing toolkit. A recent study conducted with collaborators from the University of Vermont and Cedars-Sinai describes the performance of Biocogniv's new AI-COVID software. The team found high accuracy in predicting the probability of COVID-19 infection using routine blood tests, which can help hospitals reduce the number of patients referred for scarce PCR testing.

Scientists look to meteorites for inspiration to achieve critical element-free magnet

The U.S. Department of Energy's (DOE's) Critical Materials Institute has developed a low-cost, high performance permanent magnet by drawing inspiration from an out-of-this-world source: iron-nickel alloys in meteorites. The magnet rivals widely used "Alnico" magnets in magnetic strength and has the potential to fill a strong demand for rare-earth- and cobalt-free magnets in the market.

COVID-19 may also invade the central nervous system, cause neurological illnesses

COVID-19 is known primarily as a respiratory disease, with symptoms that include cough, shortness of breath, and, in severe cases, acute respiratory distress syndrome and pneumonia. Now, researchers from Cleveland Clinic's Department of Biomedical Engineering note in a recent review that infection with the coronavirus may also affect the central nervous system and cause corresponding neurological disorders, including ischemic stroke, encephalitis, encephalopathy and epileptic seizures.

Antiepileptic drug reduces motor neuron excitability in ALS

The antiepileptic drug ezogabine reduced pathologic excitability of cortical and spinal motor neuron cells that are early signs of clinical dysfunction in people with amyotrophic lateral sclerosis (ALS), according to a study conducted by the Neurological Clinical Research Institute of Massachusetts General Hospital (MGH). In addition to providing a clearer understanding of motor neuron excitability as an important disease pathway for ALS, the multi-site study, published in JAMA Neurology, involves the first clinical investigation of ALS (also known as Lou Gehrig's disease) using a drug identified through an induced pluripotent stem cell (iPSC) model.

Restorative justice preferred among the Enga in Papua New Guinea

All human groups create systems for regulating cultural norms to maintain cooperation in society. Most large-scale populations employ a punitive judicial system where a third party doles out punishment. Yet, there's little evidence that this system achieves cooperation in a community. Advocates have long called for a more restorative justice system that repairs harm done to victims and reintegrates wrongdoers back into society. From an evolutionary perspective, humans have developed capacities to resolve disputes through restoration such as language, empathy and causal reasoning, and theory of mind to understand others and their perspectives.

Cataloging nature's hidden arsenal: Viruses that infect bacteria

Scientists are continually searching for new and improved ways to deal with bacteria, be it to eliminate disease-causing strains or to modify potentially beneficial strains. And despite the numerous clever drugs and genetic engineering tools humans have invented for these tasks, those approaches can seem clumsy when compared to the finely tuned attacks waged by phages—the viruses that infect bacteria.

Ecologists study how soil fungi respond to wildfire

In the wake of the 2017 North Bay fires, the golden hills of Santa Rosa, California, were unrecognizable. Smoky, seared and buried under ash, the landscape appeared desolate, save for some ghostly, blackened—but still alive—oak trees. For Stanford University graduate student, Gabriel Smith, whose family lives in Santa Rosa, the devastation was heartbreaking, but it also offered a unique scientific opportunity: a natural experiment on the effects of wildfires on the microbes that live in soil, which Smith studies in the form of fungi.
