Researchers from Tel Aviv University (TAU) have developed a new technology that will allow controlled encapsulation and release of molecules by exposure to UV light. Efficient encapsulation of molecules has been considered a major technological challenge, say the researchers. The new technology, which allows for efficient encapsulation and high loading capacity of molecules, might address this need. The researchers...

HSS research uncovers how UV light triggers immune activation and disease flares in lupus
HOSPITAL FOR SPECIAL SURGERY After sun exposure, people with systemic lupus erythematosus (SLE) frequently develop skin rashes, which often are accompanied by a flare of their overall disease. This connection between ultraviolet (UV) light and disease flares in lupus is well known, but the way in which UV exposure actually triggers the disease has been...

Type of ultraviolet light most effective at killing coronavirus is also the safest to use around people
by Karl Linden, The Conversation When UV light enters a cell, it breaks the bonds that hold DNA or RNA together. Credit: NASA/David Herring via WikimediaCommons Scientists have long known that ultraviolet light can kill pathogens on surfaces and in air and water. UV robots are used to disinfect empty hospital rooms, buses and trains; UV bulbs in HVAC...

Study shows first proof that a safer UV light effectively kills virus causing COVID-19
HIROSHIMA UNIVERSITY IMAGE: HIROSHIMA UNIVERSITY RESEARCHERS FOUND THAT USING ULTRAVIOLET C LIGHT WITH A 222 NM WAVELENGTH, WHICH DOESN’T HARM LIVING CELLS IN THE HUMAN EYE AND SKIN, EFFECTIVELY KILLS THE SARS-COV-2. CREDIT: HIROSHIMA UNIVERSITY A study conducted by Hiroshima University researchers found that using Ultraviolet C light with a wavelength of 222 nanometers which...

Study reveals how enzyme detects ultraviolet light damage
Damage to DNA is a constant threat to cellular life, and so it is constantly monitored and detected by a family of enzymes called RNA polymerases, resulting in subsequent repair to maintain genome integrity. In a paper published this week in the journal PNAS, researchers at University of California San Diego School of Medicine, with colleagues in Spain...

Drug that creates a ‘real sun-tan’ could prevent cancer
Scientists have developed a drug that mimics sunlight to make the skin tan, with no damaging UV radiation involved. The drug tricks the skin into producing the brown form of the pigment melanin in tests on skin samples and mice. Evidence suggests it will work even on redheads, who normally just burn in the sun....
