Researchers use fast-scanning PAM to see blood oxygenation, other functions inside living brain

Researchers studying cancer and other invasive diseases rely on high-resolution imaging to see tumors and other activity deep within the body's tissues. Using a new high-speed, high-resolution imaging method, Lihong Wang, PhD, and his team at Washington University in St. Louis were able to see blood flow, blood oxygenation, oxygen metabolism and other functions inside a living mouse brain at faster rates than ever before.

New targeted therapy promises to reduce frequency and intensity of breakouts

Acne, a scourge of adolescence, may be about to meet its ultra high-tech match. By using a combination of ultrasound, gold-covered particles and lasers, researchers from UC Santa Barbara and the private medical device company Sebacia have developed a targeted therapy that could potentially lessen the frequency and intensity of breakouts, relieving acne sufferers the discomfort and stress of dealing with severe and recurring pimples.

MIT researchers develop new nanodevice that can help overcome drug resistance

Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking the gene that confers drug resistance, then launching a new chemotherapy attack against the disarmed tumors.

Photoacoustic imaging has potential to be used as noninvasive method to detect cervical cancer

Cervical cancer is, in many ways, a shining example of how successful the war on cancer can be. Thanks largely to the advent of Pap smear screening, U.S. cervical cancer deaths decreased dramatically, by more than 60 percent, between 1955 and 1992. In the last two decades, better treatment outcomes and more powerful imaging techniques have steadily pushed 5-year survival rates ever higher.
