Engineers to build cyborg locusts, study odor-guided navigation

The inviting smell of a freshly baked cookie immediately triggers a motor response to search for the source of that smell. Often the cookie can be easily found. This everyday event that we perform without a thought is an amazing feat that combines our superior ability to smell the cookie and computational prowess to determine […]

Singamaneni to develop advanced protein imaging method

Cell-secreted proteins, such as antibodies, hormones and neurotransmitters, play a crucial role in maintaining overall health and well-being. They are also key components in disease research and in developing diagnostic tools and personalized medicines. However, current methods for studying these proteins are limited to observing large groups of cells together, which makes it difficult to […]

Advanced imaging may shed light on mechanisms behind Alzheimer’s disease

Alzheimer’s disease affects more than 6 million people in the U.S., a number expected to quadruple by 2050 if no cure is found. A hallmark of Alzheimer’s disease is misfolded amyloid deposits in the brain, which can precede the onset of dementia by decades. These deposits can restrict blood flow and thus oxygen supply to […]

Noninvasive, ultrasound-based brain biopsy is feasible, safe in people

The blood-brain barrier, the body’s way of shielding sensitive brain tissue from viruses, toxins and other harmful substances in the blood, can pose a problem for physicians caring for patients with suspected brain diseases such as cancer. Molecular and genetic information would be invaluable for confirming a diagnosis and guiding treatment decisions, but such molecules […]
