AI Effectively Detects Lung Cancer

Based in Athens, GA, Nicholas Leonard is a University of Georgia business student who has a computing certificate and is focusing his studies in areas such as data analysis. Technology informed, Athens, GA student Nicholas Leonard has a strong interest in current trends in areas such as artificial intelligence (AI).

A recent New York Times article brought focus to the potential of AI-enabled tools in detecting small lung cancers. The research brought together Google and a number of medical centers in utilizing deep learning processes. These technologies are already in use in areas such as speech recognition and in inputs that allow self-driving cars to distinguish between elements in their “field of vision.”

The issue at hand was that CT scans employed in identifying spots of definite cancer, as well as those in danger of becoming cancer, have many areas of potential human error. Radiologists may miss tumors, or mistakenly categorize benign spots as malignancies, which can lead to unproductive lung surgeries and biopsies, both of which are invasive and risky.

The research program tested AI evaluation against approximately 6,716 cases involving known cancer diagnoses and was 94 percent accurate. This outperformed a half dozen radiologists in cases where no prior scan was available, both in terms of fewer false negatives and fewer false positives. In cases where earlier scans were available, the system and physicians had roughly the same diagnostic success.

Congressional Commission Looks at Conscription and Technology Skills


A student at the University of Georgia in Athens, GA, Nicholas Leonard focuses on informatics with an emphasis on data analysis. Having undertaken analytical projects on campus in Athens, GA, Nicholas Leonard has a strong interest in areas of technology such as cybersecurity.

As reported in CSO, the United States government is currently looking to bolster its technological capacities. The congressionally mandated National Commission on Military, National and Public Service has a particular focus on modernizing the Selective Service System.

The idea is to have a “skills draft,” under which those with specific skills spanning medicine, engineering, linguistics, and cybersecurity could be conscripted in situations where the country has a “critical need.”

The practice of conscripting highly skilled workers has been around for decades, with M.A.S.H. units of doctors and nurses serving in the Korean War under such arrangements. Under current rules, medical professionals as old as 44 can be conscripted in situations of conflict.

The new wrinkle offered by the commission, which was established in 2017, is to include technology professionals who would serve with the U.S. Army Cyber Command within this umbrella. One obstacle is that while promotion and recruiting incentives can secure a certain level of cybersecurity talent, it is extremely challenging to compete with the private sector. Feasibility and advisability findings of the current process are currently being collected and will be presented to Congress in 2020.

Traveling on a Budget in the Shared Economy

A student at the University of Georgia in Athens, GA, Nicholas Leonard is a former data specialist at Carter-Young, also in Athens. In addition to his professional pursuits in GA, Nicholas Leonard enjoys travel. 

The sharing economy is making travel more accessible and budget friendly. Over 10 years ago, Airbnb disrupted the entire travel industry by providing travelers with an alternative to traditional hotel bookings. 

When people open their homes, they offer travelers a unique and culturally richer experience. Travelers looking for a bargain can easily rent a room or a house from a local. If travelers are feeling adventurous, they can borrow an RV, a houseboat, or even swap houses with another traveler.

The collaborative economy has expanded beyond accommodations to activities and tours. Apps allow visitors to arrange boat rentals, classes, and home-cooked meals. Transportation needs can also be met through ride sharing or rental agreements.

Most of the transactions in the shared economy are completed online. Travelers can conveniently make all the arrangements for their next vacation from their handheld devices.
