Es hora de abastecerse de protector solar, pero pocas opciones en los estantes de las tiendas hoy en día son seguras y efectivas, según un informe anual del Environmental Working Group (EWG), una organización sin fines de lucro que defiende la salud y el medio ambiente.

La Guía de Protectores Solares 2026 de EWG, que ya cumple 20 años, analizó 2784 productos y descubrió que solo 550 (aproximadamente el 20 %) ofrecen una protección segura y eficaz contra los rayos dañinos del sol.

La nueva guía, publicada el 19 de mayo, enumera los mejores protectores solares para bebés y niños, incluidos aquellos que ofrecen una buena relación calidad-precio , así como los mejores protectores solares recreativos diseñados para actividades al aire libre como deportes o pasar tiempo en la playa.

Además, en el informe los consumidores pueden encontrar protectores solares de uso diario mejor valorados, incluyendo cremas hidratantes con factor de protección solar (FPS) y los mejores bálsamos labiales con FPS.

Para ser recomendados por EWG, los protectores solares deben proteger contra los rayos UVA y UVB, dos tipos de rayos ultravioleta conocidos por dañar el ADN y envejecer la piel. Debido a los riesgos de inhalación, no se incluyen los aerosoles ni los polvos. Los fabricantes no pueden afirmar tener un FPS superior a 50 ni utilizar afirmaciones de marketing prohibidas por la ley federal, como “resistente al agua”.

Los consumidores suelen optar por productos más caros con un factor de protección solar (FPS) de hasta 100+, que supuestamente bloquean el 99% de los rayos UVB. Sin embargo, la diferencia en su eficacia es mínima: según el informe, un protector solar más económico con un FPS de 50+ puede bloquear el 98% de los rayos.

En algunos productos, el factor de protección solar (SPF) puede estar inflado. Un estudio revisado por pares realizado por científicos de EWG reveló que, en promedio, los protectores solares solo proporcionaban una cuarta parte de la protección contra los rayos UVA y el 59 % de la protección contra los rayos UVB indicada en las etiquetas.

Los protectores solares recomendados en la nueva guía también evitan el palmitato de retinilo, una forma de vitamina A; y las sustancias químicas sospechosas de causar cáncer, irritación de la piel, reacciones alérgicas o daños reproductivos, problemas de desarrollo o neurotoxicidad.

“El palmitato de retinilo forma parte de la familia de los retinoides que los dermatólogos recomiendan para combatir las arrugas y otros signos de envejecimiento. Estos productos incluyen advertencias para no exponer la piel al sol”, afirmó Alexa Friedman, científica sénior de EWG.

“En 2010, alrededor del 40% de los productos contenían palmitato de retinal”, dijo Friedman. “Hoy esa cifra ha bajado al 3%, lo cual es una buena noticia para los consumidores”.

De los 550 productos recomendados por EWG, 497 están elaborados principalmente con minerales que se depositan sobre la piel y desvían y bloquean físicamente los rayos solares. Dado que no se absorben en la dermis, los protectores solares a ba

(CNN) — Authorities are investigating what led a 17-year-old homeschooled wrestler and an 18-year-old to allegedly open fire on San Diego’s largest mosque on Monday, killing three people in what police have called a hate crime.

The suspects were found dead in a car on a street close to the mosque with apparent self-inflicted gunshot wounds, according to multiple law enforcement officials.

As part of their investigation, authorities are looking at hate speech scrawled on one of the weapons used in the attack, and a suicide note that contained writings about racial pride, officials have said.

The FBI is working closely with law enforcement partners, said Mark Remily, the special agent in charge of the FBI’s San Diego field office, adding investigators were interviewing family and friends of the suspects and “gathering all the evidence from the scene for review.”

The 17-year-old suspect has been identified by a law enforcement source and audio from police dispatch as Cain Clark, while the identity of the second suspect has not been released.

About two hours before the shooting was reported, police received a call from Clark’s mother who reported her son and vehicle missing, alongside several of her weapons, San Diego Police Chief Scott Wahl said.

The mother said her son was suicidal and was with a companion, both dressed in camouflage, Wahl said, which triggered a “larger threat assessment picture.” The number of weapons he took from the home led investigators to believe the teen may be a threat to others, the chief said.

Dispatch audio reviewed by CNN captures officers reporting around 12 p.m. Monday a search for “two white males… wearing all camo” that could be armed with a stolen handgun, a shotgun and a rifle.

When police arrived at the scene, they found the three deceased victims outside the mosque, who authorities have not identified. One of those killed was a security guard whose actions were described by police as “heroic” and “saved lives.”

Law enforcement began an active-shooter response and entered the mosque and an adjacent school before discovering the vehicle with the two male suspects inside, both deceased.

Authorities are carrying out search warrants to follow any leads and information to determine how the shooting unfolded and what could have been done to prevent it, Wahl said. The investigation is being aided by copious evidence, including security cameras at the mosque.

“This is a city and a community’s absolute worst nightmare as a free society,” Wahl said.

Hate speech investigated

A suicide note left in one of the suspect’s parents’ home contained writings about racial pride, multiple law enforcement officials told CNN. Additionally, hate speech was scrawled on one of the weapons that was used in the shooting, the officials said.

The specifics of the language were not immediately clear.

But there was no specific threat to any place mentioned in the note and weapons of one of the suspects who attacked the Islamic Center of San Diego, Wahl said.

“There was no specific threat, especially no speci

Hebron, Kentucky (CNN) — The race against Rep. Thomas Massie has overshadowed the campaign for Ed Gallrein, the farmer and former Navy SEAL recruited to run against him.

Yet Massie and Gallrein are the actual choices facing Republican voters Tuesday in a Kentucky primary, despite President Donald Trump looming large over a race that has become the latest stop on his revenge tour.

When the ballots are counted Tuesday night in what could become the most expensive US House primary in history, the outcome between Massie and Gallrein may provide a window into whether a deluge of attack ads and a presidential megaphone can outweigh a lifetime of relationships Massie has built across his corner of northern Kentucky.

No Republican has incensed the president more than Massie, who led the charge to release the Epstein files, voted against Trump’s landmark One Big Beautiful Bill Act and has fiercely opposed the Iran war.

Gallrein has pledged full loyalty to the Trump agenda, saying on Monday: “There has never been a more important time to stand behind our president.”

Massie, a rare contrarian in a compliant era for Republicans, acknowledges that he’s in a fight for his political life, but told supporters at an election eve rally the attacks would backfire, declaring: “They’re tried to turn me into a villain. The more they try to punish me, the more powerful I get.”

The list of Republicans falling to Trump’s wrath is growing, with Sen. Bill Cassidy of Louisiana on Saturday the latest to join the ranks of those who stood up to Trump and ultimately lost power. Whether Massie will join that group will be decided by the GOP voters of Kentucky’s 4th District.

“It’s Trump versus Massie,” said Jonathan Ruggles, vice chairman of the Lewis County Republican Party. “The ones that will not vote for Massie are voting for Trump indirectly. They’re not voting for Gallrein outright.”

Who is Ed Gallrein?

For months, Gallrein has played something of a bit part in a race that could ultimately send him to Congress.

He’s not just endorsed by Trump but was handpicked by the White House to join the race to knock out Massie. Trump has described Gallrein as “strong as hell,” a character straight out of central casting.

“He’s a true American hero,” Trump said during a visit to Kentucky earlier this spring where he stood alongside Gallrein. “He’s a great patriot and he’s doing it because he saw what this guy was doing to our country.”

Yet Trump devoted far more of his time tearing into Massie, telling the crowd: “He’s got to be voted out of office as soon as possible.”

Gallrein, 68, has never served in public office. He fell short in a Republican primary for a Kentucky state senate seat in 2024. He’s not a natural speaker or fiery orator.

But when Trump’s allies were looking for a candidate to challenge Massie, Gallrein stood out because of his long service in the military and his standing in the community as a fifth-generation farmer in Shelby County, east of Louisville.

“If we do not take advantage of this narrow window of advantage we have,” Gallrein said, “history will punish us.”

Gallrein declined to debate Massie in several forums, including a marquee event on statewide Kentucky Educational Television. At some local Republican events, Massie sat by an empty chair, always noting his opponent’s absence.

When voters asked Gallrein about his unwillingness to debate Massie, he pushed back.

“I’m debating him every day,” Gallrein told voters in the closing days of the race. “I’m talking right to the American people, just

New York (CNN) — Wholesale motor oil prices are rising rapidly, and some industry executives are warning of imminent shortages caused by the war with Iran.

Damage to key facilities in the Middle East and the shutdown of the Strait of Hormuz have combined to create a perfect storm in this tiny but critical corner of the oil market.

The risk is that some of the most popular kinds of motor oil will be in very short supply, forcing drivers to delay getting their oil changed or rely on suboptimal lubricants.

“We’re looking at shortages — I have no doubt in my mind,” Holly Alfano, CEO of the Independent Lubricant Manufacturers Association (ILMA), an industry trade group, told CNN. “It’s a big mess — and it’s not going to be resolved quickly. It could take a year or so before we see any real relief.”

The most important motor oil

Tom Glenn, president and founder of Petroleum Trends International and publisher of industry publication JobbersWorld, has chronicled the multiple rounds of dizzying price hikes on motor oil since the war started.

“Three rounds of price increases over two and a half months is unheard of. And the magnitude is stunning,” Glenn told CNN. “I’ve been in this business since 1979, and I’ve never seen anything quite like this.”

In a normal year, motor oil producers would increase prices for distributors by 70 to 80 cents a gallon. But already this year, Glenn said, some producers have lifted prices on distributors buying in bulk by $5 or more a gallon.

These price hikes are being driven by a combination of higher prices for crude oil, base oils, additives, transportation, packaging and logistics.

Not only are prices rising, but ILMA warns of an “imminent shortage” of low viscosity grade oils, including 0W-16, 0W-8 and 0W-20 — which is the most important grade of motor oil on the market today.

It’s the go-to motor oil for newer vehicles, accounting for roughly one-third of total passenger car motor oil demand last year, according to Petroleum Trends International.

‘Safety valve is effectively closed’

The motor oil situation is another reminder of the fragile nature of global supply chains.

The problem is that almost half (44%) of the most important base oil used to make motor oil, known as Group III, comes from just three Persian Gulf producers, according to ILMA.

Those Middle East supplies have been derailed by the closure of the Strait of Hormuz after the war started in late February.

Not only that, but Pearl GTL, the world’s largest gas-to-liquids (GTL) plant located in Qatar, was attacked and seriously damaged in Iran. That means one of the leading suppliers of Group III base oils has been knocked offline indefinitely.

“The US is expected to run out of Mideast Gulf-origin Group III by June,” ILMA said in a bulletin published last week.

Normally, the United States would turn to South Korea to fill the gap, but Asian refiners rely on the Strait of Hormuz for much of their crude. And Asian refiners that do have access to crude are focused on making as much jet fuel and diesel as they can to capture historically high profit margins.

Motor oil can also be made with Group II base oils, but those are also being diverted to diesel to meet demand and historically high margins.

“The Group II safety valve is effectively closed,” ILMA said in its bulletin.

Talks with Trump administration

Alfano, the ILMA CEO, said her group is hearing anecdotal reports that certain parts of the United States are already facing shortages.

“It’s going t
