Brain training games, apps, and websites are popular and it’s not hard to see why – who wouldn’t want to give their mental abilities a boost? New research suggests that brain training programs might strengthen your ability to hold information in mind, but they won’t bring any benefits to the kind of intelligence that helps you reason and solve problems.
For years scientists have been working to fundamentally understand how nanoparticles move throughout the human body. One big unanswered question is how the shape of nanoparticles affects their entry into cells. Now researchers have discovered that under typical culture conditions, mammalian cells prefer disc-shaped nanoparticles over those shaped like rods.
According to a new study, only 30 percent of the world’s youth population between the ages of 15 and 24 years old has been active online for at least five years. In South Korea, 99.6 percent of young people are active, the highest percentage in the world. The least? The Asian island of Timor Leste with less than 1 percent.
A new study from the Georgia Institute of Technology finds that older and younger people have varying preferences about what they would want a personal robot to look like. And they change their minds based on what the robot is supposed to do.
A new study has found that “waviness” in forests of carbon nanotubes dramatically reduces their stiffness. Instead of being a detriment, the waviness may make the nanotube arrays more useful as thermal interface material for conducting heat away from integrated circuits.

Using thousands of nanometer-scale wires, the researchers have developed a sensor device that converts mechanical pressure – from a signature or a fingerprint – directly into light signals that can be captured and processed optically.
Researchers at the Georgia Institute of Technology have “painted” the Mona Lisa on a substrate surface approximately 30 microns in width – or one-third the width of a human hair. The team’s creation, the “Mini Lisa,” demonstrates a technique that could potentially be used to achieve nanomanufacturing of devices because the team was able to vary the surface concentration of molecules on such short-length scales.
In 2002, the federal government mandated that corporate boards of directors include at least one “audit committee financial expert” to help avert future accounting scandals. But the title and description of that position may have an unintended negative effect on the gender diversity of corporate boards, argues Seletha Butler, assistant professor of law and ethics at Georgia Tech Scheller College of Business.
