SMU launches new cyber autonomy range

Supported by IBM software, range to help 'smart' devices against attack

The Darwin Deason Institute for Cyber Security at SMU (Southern Methodist University) is launching a new Cyber Autonomy Range, supported by IBM Security Software through IBM SkillsBuild, designed to toughen autonomous systems against cyberattacks. The range will be a controlled and isolated technology environment that can simulate possible attacks on autonomous systems that take actions automatically based on received data. IBM is providing an in-kind contribution of software and support for the project valued at over $850,000.

Cell phone data from winter snowstorm shows Dallas is resilient

Natural disasters can wreak havoc on a city, from hurricanes in Houston to winter storms in Dallas. Measuring resilience -- the length of time it will take a city to bounce back -- can help policymakers and others plan responses to future events and reveal potential vulnerabilities. An SMU research team measured Dallas’s resilience before, during, and after the February 2021 winter snowstorm and found Dallas recovered almost immediately after the snowstorm ended, indicating Dallas exhibits a great degree of resilience.

SMU Biosciences professor receives NIH grant for research on epilepsy

NIH-funded research aims to find markers predicting sudden unexpected death in people with epilepsy

An estimated 50 million people worldwide have epilepsy, making them 16 times more likely to die suddenly compared to the general population. SMU biology researcher Edward Glasscock has received a 5-year, $3 million grant from the National Institutes of Health for a study that he hopes will lead to the identification of biomarkers to help identify people at risk for sudden unexpected death in epilepsy, known as SUDEP.

Research pushes back the prehistoric timeline for apes in Africa by more than 10 million years

Pair of studies show a new model for ape evolution that may inform how our ancestors evolved to walking upright

Evidence of an early savannah grass growing millions of years earlier than previously known may fundamentally change the understanding of life in the prehistoric world. A pair of studies funded by the National Science Foundation and published in the journal Science document the earliest evidence for locally abundant open-habitat grasses in eastern Africa and how those environments likely influenced early ape evolution.

Black, Latino and other minoritized youth need better early psychosis care, SMU anthropologist learns

While youth and teens struggling with psychosis benefit the most with early intervention care, 20 to 40 percent of them drop out of care programs, if they begin them at all. But a recent study shows that ethnoracially minoritized youth, especially, are less likely to utilize an early intervention program and are more likely to drop out once they begin. What’s to blame for the higher dropout rate for care programs among minoritized youth? The study pinpoints factors such as past experience with discrimination and fears that police will be involved. Family culture and language can also play a role.

Mercury emission estimates rarely provide enough data to assess success in eliminating harmful global gold mining practice

More than 4 million women and children at risk

A global treaty called the Minamata Convention requires gold-mining countries to regularly report the amount of toxic mercury that miners are using to find and extract gold, designed to help nations gauge success toward at least minimizing a practice that produces the world’s largest amount of manmade mercury pollution. But a study of baseline mercury emission estimates reported by 25 countries – many in developing African, South American and Asian nations – found that these estimates rarely provide enough information to tell whether changes in the rate from one year to the next were the result of actual change or data uncertainty.

Sea level rose much faster in Micronesia than previously thought

Spanning vast distances, the islands of the South Pacific are thought to have been populated by humans in two distinct waves. The first one followed a northern route out of what is today the Philippines and a southern route from Taiwan and New Guinea, and a second wave, maybe 1,000 years later, followed a middle route to the islands now making up the Federated States of Micronesia. But a new finding is casting doubt on the timing of that second wave of migration, suggesting that the islands in Micronesia might have been settled much earlier than supposed.

For 400 years, Indigenous tribes buffered climate's impact on wildfires in the American Southwest

Devastating megafires are becoming more common, in part, because the planet is warming. But a new study led by SMU suggests bringing “good fire” back to the U.S. and other wildfire fire-prone areas, as Native Americans once did, could potentially blunt the role of climate in triggering today’s wildfires.

Overwhelming numbers, frequency of uninsured dialysis patients in public hospital emergency rooms may have a systemic solution

SMU analysis suggests screening protocols set by government policy – not hospitals – may be to blame for ER strain

Screening protocols to determine who qualifies for “compassionate dialysis” in hospitals with high numbers of uninsured patients are driving an unintended consequence, an SMU analysis has found. The protocols are putting too much strain on the emergency room, as measured by how long ER patients are waiting to be seen and other metrics.
