A new laser technique called photodynamic therapy appears to prevent further vision loss in people with the wet form of age-related macular degeneration. The treatment uses a red laser light to activate a toxic form of oxygen that stops abnormal blood vessel growth, potentially confining scar tissue and preventing vision loss.
A Wake Forest University professor's applied mathematics enable new adaptive optics technology to improve the sight of ground-based telescopes and new laser weapons, resulting in 'Hubble-like' improvements. The tech also enhances missile defense capabilities against enemy missiles and space junk.
MIT researchers verify coherence property in atomic beam, a key attribute of optical lasers, and extract controlled fraction of atoms from Bose-Einstein condensate to produce directional stream. This breakthrough may lead to significant innovations in nanotechnology and precision measurements at the quantum level.
The prototype non-Doppler optical sensor registers faint wind movements that anemometers cannot measure, correlating with those of anemometers in test results. It offers a low-cost alternative to complex arrays of traditional sensors and can measure both horizontal and vertical wind speeds.
Researchers use extreme X-ray power to 'movie' myoglobin protein, resolving decades-old structure-function riddle. This breakthrough enables drug developers to design better drugs by understanding dynamic molecular interactions.
Researchers at ORNL have developed a technique that combines laser light with pharmaceutical agents to selectively kill breast cancer cells. The laser delivers photons to the target tissue, activating an ingested agent that disables DNA replication and halts tumor growth.
Duke University's OK-4 optical klystron FEL, developed in Russia, has begun operating at the institution, producing intense beams of gamma rays and ultraviolet laser light. The device is expected to be used for medical research and answering questions in nuclear physics.
The Zare lab's Microprobe Two-Step Laser Microscopy technique detects organic molecules in meteorites, revealing interplanetary and interstellar origins. The method eliminates contamination sources, enabling precise analysis of polycyclic aromatic hydrocarbons and other compounds.
