A new US study published in the latest issue of the journal Scientific Reports found that Methylene Blue has proven effective in protecting from UV irradiation as well as being safe for coral reefs, providing an alternative solution to protecting human skin and the environment.

Around 80% of current sunscreens are harmful to corals as they contain Oxybenzone as a chemical UV blocker, a product known to detrimentally affect corals. In response, many countries have forbidden its use to limit the damage to coral reefs. Additionally, it could cause a lot of damages when used in sunscreen products.

The team of scientists from the University of Maryland examined the UV protection benefits of Methylene Blue from several perspectives. Human keratinocytes and skin fibroblasts were considered from young and old donors and compared UV damage with Oxybenzone.

Results showed that Methylene Blue not only absorbs UVA and UVB as the traditional sunscreen actives do, it also helps repair the DNA damage caused by UV irradiation, leading to overall better cell survival.

The team then exposed the soft Xenia umbellate coral to both Oxybenzone and Methylene Blue. The coral individuals were kept in isolated tanks as researchers monitored the growth and responses to both chemicals. The results showed Oxybenzone-treated Xenia corals suffered drastic bleaching and die-off in less than a week after exposure, while Methylene Blue exposure had no negative effects on coral health even at a relatively high concentration (1 micromolar).

In addition, the researchers also compared Methylene Blue with other skincare antioxidants such as Vitamin A (Retinol) and Vitamin C. This was to examine potential differences in their ability to reduce cellular oxidative stress.

"We are extremely excited to see that skin fibroblasts, derived from both young and old individuals, have improved so much in terms of proliferation and cellular stress in a methylene blue-containing cell culture medium. We found that the combination of Methylene Blue and Vitamin C could deliver amazing anti-aging effects, particularly in skin cells from older donors, suggesting a strong synergistic reaction between these two beneficial antioxidants," said Dr. Kan Cao, senior author and professor of cell biology and molecular genetics at the University of Maryland, in a report.

A rapidly growing wildfire raged across an upscale section of Los Angeles on Tuesday, destroying numerous buildings and creating traffic jams as more than 30,000 people evacuated, while a second blaze doubled in size some 30 miles inland.

At least 2,921 acres (1,182 hectares) of the Pacific Palisades area between the coastal towns of Santa Monica and Malibu had burned by the Palisades Fire, officials said, after they had already warned of extreme fire danger from powerful winds that arrived following extended dry weather.

A fire official told local television station KTLA that several people were injured, some with burns to faces and hands. The official added that one female firefighter had sustained a head injury.

The second blaze dubbed the Eaton Fire broke out some 30 miles (50 km) inland near Pasadena and doubled in size to 400 acres (162 hectares) in a few hours, according to Cal Fire.

Almost 100 residents from a nursing home in Pasadena were evacuated, according to CBS News. Video showed elderly residents, many in wheelchairs and on gurneys, crowded onto a smokey and windswept parking lot as fire trucks and ambulances attended.

Fire officials said a third blaze named the Hurst Fire had started in Sylmar, in the San Fernando Valley northwest of Los Angeles, prompting evacuations of some nearby residents.

PALISADES FIRE

Witnesses reported a number of homes on fire with flames nearly scorching their cars when people fled the hills of Topanga Canyon, as the fire spread from there down to the Pacific Ocean.

Local media reported the fire had spread north, torching homes near Malibu.

Los Angeles Fire Chief Kristin Crowley had earlier told a press conference that more than 25,000 people in 10,000 homes were threatened.

Firefighters in aircraft scooped water from the sea to drop it on the nearby flames. Flames engulfed homes and bulldozers cleared abandoned vehicles from roads so emergency vehicles could pass, television images showed.

The fire singed some trees on the grounds of the Getty Villa, a museum loaded with priceless works of art, but the collection remained safe largely because of preventive efforts to trim brush surrounding the buildings, the museum said.

With only one major road leading from the canyon to the coast, and only one coastal highway leading to safety, traffic crawled to a halt, leading people to flee on foot.

Cindy Festa, a Pacific Palisades resident, said that as she evacuated out of the canyon, fires were "this close to the cars," demonstrating with her thumb and forefinger.

"People left their cars on Palisades Drive. Burning up the hillside. The palm trees - everything is going," Festa said from her car.

Before the fire started, the National Weather Service had issued its highest alert for extreme fire conditions for much of Los Angeles County from Tuesday through Thursday, predicting wind gusts of 50 to 80 mph (80 to 130 kph).

With low humidity and dry vegetation due to a lack of rain, the conditions were "about as bad as it gets in terms of fire weather," the Los Angeles office of the National Weather Service said on X.

Governor Gavin Newsom, who declared a state of emergency, said the state positioned personnel, firetrucks and aircraft elsewhere in Southern California because of the fire danger to the wider region, he added.

The powerful winds changed President Joe Biden's travel plans, grounding Air Force One in Los Angeles. He had planned to make a short flight inland to the Coachella Valley for a ceremony to create two new national monuments in California but the event was rescheduled for a later date at the White House.

"I have offered any federal assistance that is needed to help suppress the terrible Pacific Palisades fire," Biden said in a statement. A federal grant had already been approved to help reimburse the state of California for its fire response, Biden said.

Pacific Palisades is home to several Hollywood stars. Actor James Woods said on X he was able to evacuate but added, "I do not know at this moment if our home is still standing."

Actor Steve Guttenberg told KTLA television that friends of his were impeded from evacuating because others had abandoned their cars on the road.

"It's really important for everybody to band together and don't worry about your personal property. Just get out," Guttenberg said. "Get your loved ones and get out."
