I had a heat pump installed about a year ago. It came with one free service and the installing company has been calling me almost every week to come out and do the complimentary tune up. I know that I obviously should take a free tune up, but it made me wonder. How often do I actually need this done? What are they actually "tuning up"?

The Supreme Court on Tuesday refused to block a Texas law requiring pornographic websites to verify the age of their users.

The justices rejected an emergency appeal filed by the Free Speech Coalition, a trade association for the adult entertainment industry. The provision of House Bill 1181, signed into law by Gov. Greg Abbott, remains in effect even as the association’s full appeal is weighed by the Supreme Court.

There were no noted dissents from the court’s one-sentence order.

Similar age verification laws have passed in other states, including Arkansas, Indiana, Kansas, Louisiana, Mississippi, Montana, Oklahoma, Utah and Virginia.

The Texas law carries fines of up to $10,000 per violation that could be raised to up to $250,000 per violation by a minor.

The China National Space Administration (CNSA) has released a video of its concept for a lunar base to be developed across the next couple of decades.

CNSA unveiled the video on Wednesday (April 24) as part of the country's annual space day celebrations. The project is known as the International Lunar Research Station (ILRS) and was jointly announced in 2021 by China and Russia.

China is now leading the moon base initiative and attempting to attract international partners for the endeavor. So far, alongside China, Russia, Venezuela, Pakistan, Azerbaijan, Belarus, South Africa, Egypt, Thailand and Nicaragua have joined the initiative, according to Space News.

One curious detail of the video is the presence of a retired NASA Space Shuttle appearing to lift off from a launch pad in the background.

Federal auto regulators announced Friday they are opening an investigation into the safety of Tesla’s Autopilot feature, less than a week after a Tesla driver believed to be using it allegedly struck and killed a motorcyclist in Monroe.

Jeffrey Nissen, 28, of Stanwood was on his way home from work on Highway 522 when the Tesla Model S struck his blue 2003 Yamaha R6, Nissen’s fiancée Janae Hutchinson said Thursday.

Washington State Patrol spokesperson Chris Loftis said the agency is still investigating whether the Tesla driver was using Autopilot — a combination of cruise control and Autosteer intended to maintain the car’s set speed while keeping a safe distance from other vehicles and in its driving lane. The crash was among a rising number of collisions in Washington involving cars equipped with the technology, mostly Teslas.

Washington saw 17 such crashes last year compared to 12 in 2022, according to National Highway Traffic Safety Administration data. Of the 35 crashes in Washington involving Autopilot-equipped cars reported by the National Highway Traffic Safety Administration between Sept. 1, 2021 and March 15, 2024, all but three were Teslas, according to the data.

Federal regulators are challenging patents on 20 brand name drugs, including the blockbuster weight-loss injection Ozempic, in the latest action by the Biden administration targeting industry practices that drive up pharmaceutical prices.

The Federal Trade Commission on Tuesday sent warning letters to 10 drugmakers, taking issue with patents on popular drugs for weight loss, diabetes, asthma and other reparatory conditions. The letters allege that certain patents filed by Novo Nordisk, GlaxoSmithKline, AstraZeneca and seven other companies are inaccurate or misleading.

Brand-name drugmakers use patents to protect their medicines and stave off cheaper, generic medicines. Most blockbuster drugs are protected by dozens of patents covering various ingredients, manufacturing processes and intellectual property. Generic drugmakers can only launch their own cheaper versions if the patents have expired or are successfully challenged in court.

“By filing bogus patent listings, pharma companies block competition and inflate the cost of prescription drugs, forcing Americans to pay sky-high prices for medicines they rely on,” said FTC Chair Lina Khan, in a statement.

Russia has arrested two Russian journalists on “extremism” charges in recent days, the latest moves in a continuing crackdown targeting independent reporters and media outlets. A third Russian journalist, with Forbes Russia, was charged with publishing what authorities called “fake news.”

The increasing use of anti-extremism laws to prosecute reporters — one piece of a larger campaign to stifle domestic dissent during Russia’s war in Ukraine — is likely to have a further chilling effect on the few independent journalists still operating in Russia, many of them freelancers or employees of small outlets with few legal protections.

The Associated Press on Saturday reported that video journalist Sergey Karelin, who has worked with the AP, Deutsche Welle and other international outlets had been arrested Friday in the Murmansk region in northern Russia and charged with extremism. He was placed in custody pending trial.

Protests are roiling college campuses across the U.S. as upcoming graduation ceremonies are threatened by disruptive demonstrators, with students and others sparring over Israel’s military offensive in Gaza and its mounting death toll.

Many campuses were largely quiet over the weekend as demonstrators stayed by tents erected as protest headquarters, although a few colleges saw forced removals and arrests. Many students are demanding their universities cut financial ties with Israel over the large-scale operation in Gaza it says was launched to stamp out the militant Palestinian group Hamas.

Protesters on both sides of the rancourous debate shouted and shoved each other during dueling demonstrations Sunday at the University of California, Los Angeles. The university stepped up security after “some physical altercations broke out among demonstrators,” Mary Osako, vice chancellor for UCLA Strategic Communications, said in a statement. There were no reports of arrests or injuries.

About 275 people were arrested on Saturday at various campuses including Indiana University at Bloomington, Arizona State University and Washington University in St. Louis. The number of arrests nationwide approached 900 since New York police removed a pro-Palestinian protest encampment at Columbia University and arrested more than 100 demonstrators on April 18.

Tesla has seen its profits more than halve this year, and says it will bring forward the launch of new models after announcing thousands of job cuts to try to reverse its fortunes.

Despite plans to bring forward new models originally planned for next year the firm is cutting its workforce.

Tesla said it would lose 3,332 jobs in California and 2,688 positions in Texas, starting mid-June.

The cuts in Texas represent 12% of Tesla's total workforce of almost 23,000 in the area where its gigafactory and headquarters are located.

The world is seeing a near breakdown of international law amid flagrant rule-breaking in Gaza and Ukraine, multiplying armed conflicts, the rise of authoritarianism and huge rights violations in Sudan, Ethiopia and Myanmar, Amnesty International warned Wednesday as it published its annual report.

The human rights organization said the most powerful governments, including the United States, Russia and China, have led a global disregard for international rules and values enshrined in the Universal Declaration of Human Rights, with civilians in conflicts paying the highest price.

Agnes Callamard, Amnesty’s secretary general, said the level of violation of international order witnessed in the past year was “unprecedented.”

“Israel’s flagrant disregard for international law is compounded by the failures of its allies to stop the indescribable civilian bloodshed meted out in Gaza,” she said. “Many of those allies were the very architects of that post-World War Two system of law.”

U.S. health officials issued a warning Tuesday about counterfeit Botox injections that have sickened 22 people.

Half of the individuals have ended up in the hospital, according to the Centers for Disease Control and Prevention. The agency issued an alert to doctors on Tuesday.

The cases started in early November and have been reported in 11 states. The CDC said the shots were administered by unlicensed or untrained individuals or in settings like homes or spas. Most of the people said they got injections of botulinum toxin for cosmetic reasons.

Six people were treated for suspected botulism, health officials said. When it gets into the bloodstream, botulinum toxin can cause botulism, a deadly disease that starts with double or blurred vision, drooping eyelids, slurred speech, difficulty swallowing and difficulty breathing.

Hundreds of high school and college students across the Puget Sound region walked out of school Tuesday to protest Israel’s fighting in Gaza.

Some gathered outside their school’s front offices, where they listened to student leaders chant into megaphones. Others left school and flocked to Cal Anderson Park in Seattle’s Capitol Hill neighborhood to do the same. Anywhere from 20 to 150 students turned out at each of a dozen Seattle-area schools, but overall the protests were calm and low-key.

“We demand a free Palestine,” and “Free, free Palestine,” students chanted at Cal Anderson Park. They carried posters that read “Genocide is never justified” and “Cease-fire now” during a small march down streets in West Seattle.

A 56-year-old Snohomish man had set his Tesla Model S on Autopilot and was looking at his cellphone on Friday when he struck and killed a motorcyclist in front of him in Monroe, court records show.

A Washington State Patrol trooper arrested the Tesla driver at the crash site on Highway 522 at Fales Road shortly before 4 p.m. on suspicion of vehicular manslaughter, according to a probable cause affidavit.

The motorcyclist, Jeffrey Nissen, 28, of Stanwood, died at the scene, records show.

The Tesla driver told a state trooper he was driving home from having lunch in Bothell and was looking at his phone when he heard a bang and felt his car lurch forward, accelerate and hit the motorcyclist, according to the affidavit.

The man told the trooper his Tesla got stuck on top of the motorcyclist and couldn’t be moved in time to save him, the affidavit states.

The trooper cited the driver’s “inattention to driving, while on autopilot mode, and the distraction of the cell phone while moving forward,” and trusting “the machine to drive for him” as probable cause for a charge of vehicular manslaughter, according to the affidavit.

The man was booked into the Snohomish County Jail and was released Sunday after posting bond on his $100,000 bail, jail records show.
