• Fake email addresses - Malicious actors sometimes send from email addresses made to look like an official email address but in fact is missing a letter(s), misspelled, replaces a letter with a lookalike number (e.g. “O” and “0”), or originates from free email services that would not be used for official communications.
Around 1980, Michael W. Berns, a professor of biology at the University of California, Irvine, founded an institute focusing on the then-new technology of lasers.After receiving a National Institutes of Health biotechnology grant, [3]: 328–331 he established a laboratory for laser microscopy, the Laser Microbeam Program (LAMP).

Rox Anderson proposed the medical application of the free-electron laser in melting fats without harming the overlying skin. [42] At infrared wavelengths , water in tissue was heated by the laser, but at wavelengths corresponding to 915, 1210 and 1720 nm , subsurface lipids were differentially heated more strongly than water.
However a number of other beam types have been used to trap particles, including high order laser beams i.e. Hermite-Gaussian beams (TEM xy), Laguerre-Gaussian (LG) beams (TEM pl) and Bessel beams. Optical tweezers based on Laguerre-Gaussian beams have the unique capability of trapping particles that are optically reflective and absorptive.

In medicine, proton therapy, or proton radiotherapy, is a type of particle therapy that uses a beam of protons to irradiate diseased tissue, most often to treat cancer.The chief advantage of proton therapy over other types of external beam radiotherapy is that the dose of protons is deposited over a narrow range of depth; hence in minimal entry, exit, or scattered radiation dose to healthy ...
On February 26, 2009, NIF fired all 192 laser beams into the target chamber. [100] On March 10, 2009, NIF became the first laser to break the megajoule barrier, delivering 1.1 MJ of UV light, known as 3ω (from third-harmonic generation), to the target chamber center in a shaped ignition pulse. [101] The main laser delivered 1.952 MJ of IR. [102]
The usefulness of red laser, laser acupuncture, and reflexology in the treatment of RA patients is not well enough demonstrated. [58] A 2019 systematic review and meta-analysis found evidence for pain reduction in osteoarthritis. [15] While it does not appear to improve pain in temporomandibular disorders, it may improve function. [59]
