Columbia researchers develop new non-invasive approach to permanently correct vision

Nearsightedness, or myopia, is an increasing problem around the world. There are now twice as many people in the US and Europe with this condition as there were 50 years ago. In East Asia, 70 to 90 percent of teenagers and young adults are nearsighted.

Miniaturized device offers new way to gain insight into cell processes and communication

Like humans, cells of the same species each have a distinct "personality." When confronted with an external stimulus like a virus, they each secrete a different quantity of molecules and communicate with each other to a varying degree.

New technology detects the 'glow' to guide brain tumor resection

Research by Barrow Neurological Institute physicians and University of Washington scientists on novel imaging technology for malignant brain tumors was published in the April issue of World Neurosurgery.

European project InSPECT develops miniature photonics spectrometers for tissue diagnostics

Today physicians are still severely hampered by the lack of precision of the needle tip location during a biopsy. Looking at lung cancers, 25% of the diagnoses suffer a false negative outcome through traditional biopsy methods. In the future, this can be avoided: for the first time, the European project InSPECT developed miniature spectrometers with integrated light sources enabling guided sensing.

Deep learning enhances smartphone microscopes into laboratory-grade equipments

Researchers at the UCLA Samueli School of Engineering have demonstrated that deep learning, a powerful form of artificial intelligence, can discern and enhance microscopic details in photos taken by smartphones. The technique improves the resolution and color details of smartphone images so much that they approach the quality of images from laboratory-grade microscopes.

New 'nanotweezers' could pave way for innovations in health monitoring and mobile technology

It's difficult to conceptualize a world where humans could casually manipulate nanoscale objects at will or even control their own biological matter at a cellular level with light.

Researchers develop ultrathin endoscope to capture neurons firing deep in the brain

Researchers have developed an endoscope as thin as a human hair that can image the activity of neurons in the brains of living mice. Because it is so thin, the endoscope can reach deep into the brain, giving researchers access to areas that cannot be seen with microscopes or other types of endoscopes.

New laser source for infrared spectromicroscopy could enable early diagnosis of pathologies

Sébastien Février, reader at the University of Limoges and researcher at XLIM, and his team demonstrated that a bench-top, optical fiber-based laser source can be used to perform infrared spectromicroscopy with a precision rivaling, and in some regards even surpassing, that of experiments at large-scale synchrotron facilities.

Using harmless red or infrared light to diagnose breast cancer

Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided.

New optical point-of-care device could enhance screening for thyroid nodules

Early diagnosis in thyroid cancer can improve a patient's likelihood of recovery, but current screening methods use instruments with poor sensitivity and can yield inaccurate results.

Cannabis Quality and Contamination Testing

Dr. Bob Clifford has published and presented over 125 papers in the fields of food, pharmaceutical, environmental, energy, geology, material science, photonics, and cannabis. However, his true love is in food. After graduating with his Ph.D., he left his job with the FDA for Shimadzu where he has worked for the last 26 years.
