Students’ image tool offers sharper signs, earlier detection in the lab or from space

University of British Columbia Okanagan campus
Peer-Reviewed Publication

A group of UBC Okanagan students has helped create technology that could improve how doctors and scientists detect everything from tumours to wildfires.

Working under the guidance of Associate Professor Xiaoping Shi from UBCO’s Department of Computer Science, Mathematics, Physics and Statistics, the students designed and tested a system called an adaptive multiple change point energy-based model segmentation (MEBS).

A Mount Sinai-Led team creates model for understanding how the brain’s decision-making is impacted in psychiatric disorders

The Mount Sinai Hospital / Mount Sinai School of Medicine
Peer-Reviewed Publication

Scientists from the Icahn School of Medicine at Mount Sinai, working in collaboration with a team from the University of Texas at El Paso, have developed a novel computational framework for understanding how a region of the brain known as the striatum is involved in the everyday decisions we make and, importantly, how it might factor into impaired decision-making by individuals with psychiatric disorders like post-traumatic stress disorder and substance use disorder.

Helicobacter pylori eradication may raise risk of reflux esophagitis, meta-analysis warns

First Hospital of Jilin University
Peer-Reviewed Publication

A new systematic review and meta-analysis published in eGastroenterology reveals that eradication of Helicobacter pylori (H. pylori) may increase the risk of reflux oesophagitis (RE) occurrence or recurrence. By analyzing data from 30 prospective cohort studies and randomized controlled trials, the study found a significantly higher RE risk in patients receiving H. pylori eradication therapy, especially with longer follow-up periods. Although geographic region, age, and baseline disease modified the effect, the trend was generally consistent. Clinicians are advised to consider individual patient profiles before initiating eradication therapy. These findings challenge existing assumptions about the uniformly beneficial role of H. pylori eradication.

Tiny robots use sound to self-organize into intelligent groups

Penn State
Peer-Reviewed Publication

Animals like bats, whales and insects have long used acoustic signals for communication and navigation. Now, an international team of scientists have taken a page from nature's playbook to model micro-sized robots that use sound waves to coordinate into large swarms that exhibit intelligent-like behavior. The robot groups could one day carry out complex tasks like exploring disaster zones, cleaning up pollution, or performing medical treatments from inside the body, according to team lead Igor Aronson, Huck Chair Professor of Biomedical Engineering, Chemistry, and Mathematics at Penn State.
