When scientists and engineers use the word materials, they mean any naturally occurring substance manipulated by humans to make things. Beginning with the first metals, discovered by trial and error thousands of years ago, the drive to develop materials that better serve human needs has played a central role in the rise of complex societies.

Modern researchers have moved past haphazard experimentation. Today they examine materials at every level – from the nanoscale to the visible and tangible macroscale – to understand why a material behaves as it does.

T-cells are the body’s sentinels, patrolling every corner of the body in search of foreign threats such as bacteria and viruses. Receptor molecules on the T-cells identify invaders by recognizing their specific antigens, helping the T-cells discriminate attackers from the body’s own cells. When they recognize a threat, the T-cells signal other parts of the immune system to confront the invader.

Georgia Tech recently held a recognition reception and honors luncheon and awarded two faculy members from the George W. Woodruff School of Mechanical Engineering with honors.

On April 24, 2014 at the McCamish Pavillion, more than 900 seniors from across Georgia Tech will showcase their final senior design projects at the Capstone Design Expo. The Senior Design (Capstone Design) course, a culmination of undergraduate education, teaches students about the design process and allows them one last opportunity to truly take advantage of Georgia Tech’s numerous resources to launch their own venture, solve a social need, or work with an industry sponsor.

The 10 graduate students are discussing stem cell population analysis, when it’s time. Before they can continue the discussion, Todd McDevitt, the instructor, has to do one thing — turn on the TV.

The venomous sidewinder rattlesnake has always been able to kill you - but now could it help save you, too.

A new microfluidic method for evaluating drugs commonly used for preventing heart attacks has found that while aspirin can prevent dangerous blood clots in some at-risk patients, it may not be effective in all patients with narrowed arteries. The study, which involved 14 human subjects, used a device that simulated blood flowing through narrowed coronary arteries to assess effects of anti-clotting drugs.

Arthur E. Bergles, (78), of Centerville, Massachusetts, an accomplished Professor of Engineering, passed away Monday, March 17, 2014, of a malignant brain tumor.
