Stiffness-dependent separation of cells
Gautam Rangavajla

Early diagnosis of disease is always a priority in medical treatment. In general, the earlier a disease is detected and treated, the greater the patient's chance of recovery. Many diseases including cancer and pathogenic conditions such as malaria result in disease-affected cells (e.g. cancer cells or malaria-infected red blood cells) in the blood. The ablility to rapidly detect these cells can lead to better diagnoses and treatments and an improved outcome for patients. Recent research from a Georgia Tech lab has developed an innovative technique that could isolate disease cells in a fluid medium, which may lead to new tools for detecting disease cells and studying disease.

The pervasive applications of nanotechnology
Amrita Banerjee

Nanotechnology is at the forefront of being pervasive in all aspects of our daily lives. In the complimentary fields of electronics and nanotechnologies, the application possibilities for the benefit of mankind are vast. Nanotechnology-based advances include the potential to revolutionize medicine, contribute to the protection of the earth's environment, enhance the capabilities of homeland security, provide new approaches in energy creation and storage, as well as improve the size, performance, and effectiveness of many other traditional consumer and industrial applications throughout the globe.

The origin & evolution of RNA: Molecular midwives and their role in nucleic acid polymerization
Alex George

The transition from the world of RNA to DNA four billion years ago required a helping-hand.

The origin of life has long been predicted to have arisen from simple, self-replicating molecular systems. Many scientists have supported the RNA world hypothesis which states that RNA was the first form of life on earth due to its versatility as bearers of genetic information as well as having the ability to catalyze chemical reactions.

Novel stem cell culture leads to osteoporosis prevention in diabetics
Brandon Philbrick

New insights reveal the cellular relationship between osteoporosis and diabetes, and provide an avenue to potential medical therapies. The researchers in the Temenoff lab at Georgia Tech have taken it upon themselves to examine this relationship between diabetes, osteoporosis, and the cellular bone marrow environment.
