WASHINGTON — NASA’s pioneering Parker Solar Probe made history Tuesday, flying closer to the sun than any other spacecraft, with its heat shield exposed to scorching temperatures topping 930 degrees Celsius (1,700 degrees Fahrenheit). 

Launched in August 2018, the spaceship is on a seven-year mission to deepen scientific understanding of our star and help forecast space-weather events that can affect life on Earth. 

Tuesday’s historic flyby should have occurred at precisely 11:53 Greenwich Mean Time, although mission scientists will have to wait until Friday for confirmation as they lose contact with the craft for several days due to its proximity to the sun. 

“Right now, Parker Solar Probe is flying closer to a star than anything has ever been before,” at 6.1 million kilometers (3.8 million miles) away, NASA official Nicky Fox said in a video on social media Tuesday morning.  

“It is just a total ‘yay, we did it,’ moment.” 

If the distance between Earth and the sun is the equivalent to the length of an American football field, 109.7 meters, the spacecraft should have been about four meters from the end zone at the moment of closest approach — known as perihelion. 

“This is one example of NASA’s bold missions, doing something that no one else has ever done before to answer long-standing questions about our universe,” Parker Solar Probe program scientist Arik Posner said in a statement on Monday. 

“We can’t wait to receive that first status update from the spacecraft and start receiving the science data in the coming weeks.” 

So effective is the heat shield that the probe’s internal instruments remain near room temperature — around 29 C (85 F) — as it explores the sun’s outer atmosphere, called the corona. 

Parker will also be moving at a blistering pace of around 690,000 kilometers per hour (430,000 miles per hourph), fast enough to fly from the U.S. capital, Washington, to Japan’s Tokyo in under a minute. 

“Parker will truly be returning data from uncharted territory,” said Nick Pinkine, mission operations manager at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.  

“We’re excited to hear back from the spacecraft when it swings back around the sun.” 

By venturing into these extreme conditions, Parker has been helping scientists tackle some of the sun’s biggest mysteries: how solar wind originates, why the corona is hotter than the surface below, and how coronal mass ejections — massive clouds of plasma that hurl through space are formed. 

The Christmas Eve flyby is the first of three record-setting close passes, with the next two — on March 22 and June 19, 2025 — both expected to bring the probe back to a similarly close distance from the Sun.

NEW YORK — A NASA spacecraft aims to fly closer to the sun than any object sent before.

The Parker Solar Probe was launched in 2018 to get a close-up look at the sun. Since then, it has flown straight through the sun’s corona: the outer atmosphere visible during a total solar eclipse.

The next milestone: closest approach to the sun. Plans call for Parker on Tuesday to hurtle through the sizzling solar atmosphere and pass within a record-breaking 6 million kilometers of the sun’s surface.

At that moment, if the sun and Earth were at opposite ends of a football field, Parker “would be on the 4-yard line,” said NASA’s Joe Westlake.

Mission managers won’t know how Parker fared until days after the flyby since the spacecraft will be out of communication range.

Parker planned to get more than seven times closer to the sun than previous spacecraft, hitting 690,000 kph at closest approach. It’s the fastest spacecraft ever built and is outfitted with a heat shield that can withstand scorching temperatures up to 1,371 degrees Celsius.

It’ll continue circling the sun at this distance until at least September. Scientists hope to better understand why the corona is hundreds of times hotter than the sun’s surface and what drives the solar wind, the supersonic stream of charged particles constantly blasting away from the sun.

The sun’s warming rays make life possible on Earth. But severe solar storms can temporarily scramble radio communications and disrupt power.

The sun is currently at the maximum phase of its 11-year cycle, triggering colorful auroras in unexpected places.

“It both is our closest, friendliest neighbor,” Westlake said, “but also at times is a little angry.”

BEIRUT — Since the fall of former Syrian President Bashar Assad, industrial-scale manufacturing facilities of the amphetamine-like stimulant Captagon have been uncovered around the country, which experts say fed a $10 billion annual global trade in the highly addictive drug.

Among the locations used for manufacturing the drug were the Mazzeh air base in Damascus, a car-trading company in Latakia and a factory that once made snack chips in the Damascus suburb of Douma. Government forces seized the factory in 2018.

“Assad’s collaborators controlled this place. After the regime fell … I came here and found it on fire,” Firas al-Toot, the original owner of the factory, told The Associated Press. “They came at night and lit the drugs on fire but couldn’t burn everything.”

“From here, Captagon pills emerged to kill our people,” Abu Zihab, an activist with Hayat Tahrir al-Sham, the main group now ruling the country, said while his group gave journalists access to the site.

Syria’s nearly 14-year-old civil war fragmented the country, crumbled the economy and created fertile ground for the production of the drug. Militias, warlords and the Assad government transformed the production of Captagon from a small-scale operation run by criminal groups into a billion-dollar industrial revenue stream.

The recent ousting of Assad has disrupted these networks and has given a closer look at its operations — revealing the workings of a war economy that sustained Assad’s power over Syria. Experts say the change in Syria might create an opportunity to dismantle the Captagon industry.

How did Syria build its Captagon empire?

Captagon was first developed in Germany in the 1960s as a prescription stimulant for conditions like narcolepsy. It was later outlawed due to heart issues and its addictive properties.

Its amphetamine-like effects made it popular in the Middle East among both elites and fighters, as it enhanced focus and reduced fatigue.

Assad’s government recognized an opportunity in the cheaply manufactured drug amid Syria’s economic turmoil and the heavy sanctions imposed on it.

Captagon is produced through a simple chemical process that involves mixing amphetamine derivatives with excipients to form tablets, typically in makeshift labs.

The Captagon trade began industrializing around 2018-19 as the Assad regime — and other armed groups in Syria — invested in production facilities, warehouses and trafficking networks. This allowed Syria to emerge as the largest producer of Captagon globally, with some production also occurring in Lebanon.

Most seized consignments of Captagon originated from Syria, according to data by the New Lines Captagon Trade Project, an initiative of the New Lines Institute think tank.

Evidence of the Assad regime’s sponsorship of the Captagon industry is overwhelming, the report published in May said. The Security Office of the 4th Armored Division of the Syrian Arab Army, headed by Bashar al-Assad’s brother Maher oversaw operations and created a coordinated production system, the report added.

Where and how was Captagon smuggled?

Captagon was smuggled across borders in trucks and cargo shipments. Sometimes the drugs were concealed in food, electronics and construction materials to evade detection.

The primary smuggling routes were Syria’s porous borders with Lebanon, Jordan and Iraq, from which the drug was distributed throughout the region. The leading markets are wealthy Gulf countries like Saudi Arabia and the United Arab Emirates.

In Lebanon, the Captagon trade has flourished, particularly near the Syrian border and in the Bekaa Valley. Lebanese authorities struggled to curb the flow of Captagon from Syria, which analysts say was facilitated by the Hezbollah militant group.

Following the discovery of crates of fruit meticulously packed with bundles of the drug hidden among pomegranates and oranges, Saudi Arabia and the UAE implemented bans on Lebanese agricultural products.

Captagon has also found its way as far as Southeast Asia and parts of Europe.

How much revenue did it produce for the Assad regime?

The annual global trade in Captagon had an estimated value of $10 billion, with the ousted Assad family’s annual profit reaching around $2.4 billion, according to Caroline Rose, director of the New York-based New Lines Institute Captagon Trade Project.

“Seeing the uncovering of so many industrial-scale facilities affiliated with the regime was shocking but not surprising. There was extensive evidence linking key regime-aligned cronies and Assad family members to the trade,” said Rose, whose organization tracks all publicly recorded Captagon seizures and lab raids.

The discovery of the facilities, she said, confirmed “the concrete relationship between Captagon and the former regime.”

The exact number of factories in Syria remains unclear, but experts and HTS members estimate that there are likely hundreds spread throughout the country.

Captagon as a narco-diplomatic tool

While neighboring countries have long sought to curb drug trafficking, their influence over Assad was limited.

Saudi Arabia imposed strict penalties for Captagon trafficking and enhanced border security, collaborating with other Gulf states to monitor smuggling routes. However, these efforts faced challenges from the complex networks operating across Syria, Lebanon and Jordan.

Captagon provided Assad’s government with leverage to end his political isolation. In recent years, as several Arab states reestablished ties with him, stopping the Captagon trade was a key demand in talks aimed at normalizing relations. In May 2023, Syria was readmitted to the Arab League, where it had been suspended since 2011 due to Assad’s brutal crackdown on protesters.

Syria pledged to clamp down on smuggling, leading to the formation of a regional security coordination committee.

Shortly after the summit and in a possible sign of behind-the-scenes trade-offs, Jordan intensified surveillance along the Syrian border. Activists and experts attributed airstrikes on a known drug kingpin’s home and on a suspected Captagon factory near Daraa to Jordan, likely with Assad’s consent.

The future of Captagon in post-Assad Syria

Assad has turned Syria into “the largest Captagon factory in the world,” HTS leader Ahmad al-Sharaa stated in a victory speech at Damascus’s Umayyad Mosque on Dec. 8. “Today, Syria is being cleansed, thanks to the grace of Almighty God.”

While Assad and his circle may have been the primary beneficiaries, there is also evidence that Syrian opposition groups were involved in drug smuggling. Rebel groups, local militias and organized crime networks manufactured and smuggled the drug to finance their operations, analysts say.

“Likely, we will see a short-term supply reduction in the trade, with a decline in the size and frequency of seizures as industrial-scale production is largely halted. However, criminal actors are innovative, likely seeking out new locations to engage in production and smuggling, particularly as demand levels remain stable,” Rose said.

They may also “seek out alternative illicit trades to engage in instead,” she said.

In addition to dismantling the Captagon trade, the country’s transitional government should “establish programs for economic development that will incentivize Syrians to participate in the country’s formal, licit economic sphere,” Rose said.

NEW YORK — Teen drug use hasn’t rebounded from its drop during the early years of the COVID-19 pandemic, according to the results from a large annual national survey released Tuesday.

About two-thirds of 12th graders this year said they hadn’t used alcohol, marijuana, cigarettes or e-cigarettes in the previous 30 days. That’s the largest proportion abstaining since the annual survey started measuring abstinence in 2017.

Among 10th graders, 80% said they hadn’t used any of those substances recently, another record. Among eighth graders, 90% didn’t use any of them, the same as was reported in the previous survey.

The only significant increase occurred in nicotine pouches. About 6% of 12th graders saying they’d used them in the previous year, up from about 3% in 2023.

Whether that has the makings of a new public health problem is unclear. The University of Michigan’s Richard Miech, who leads the survey, said: “It’s hard to know if we’re seeing the start of something, or not.”

The federally funded Monitoring the Future survey has been operating since 1975. This year’s findings are based on responses from about 24,000 students in grades eight, 10 and 12 in schools across the country. The survey is “one of the best, if not the best” source of national data for substance use by teens, said Noah Kreski, a Columbia University researcher who has studied teen drug use.

Early in the pandemic, students across the country were told not to go to schools and to avoid parties or other gatherings. They were at home, under parents’ supervision. Alcohol and drug use of all kinds dropped because experimentation tends to occur with friends, spurred by peer pressure, experts say.

As lockdowns ended, “I think everyone expected at least a partial rebound,” Miech said.

Even before the pandemic, there were longstanding declines in teen cigarette smoking, drinking and use of several types of drugs. Experts theorized that kids were staying home and communicating on smartphones rather than hanging out in groups, where they sometimes tried illicit substances.

But marijuana use wasn’t falling before the pandemic. And vaping was on the upswing. It was only during the pandemic that those two saw enduring declines, too.

Some experts wonder if the pandemic lockdowns had a deeper influence.

Miech noted that a lot of teens who experiment with e-cigarettes or drugs start in the 9th grade, sometimes because older adolescents are doing it. But the kids who were 9th graders during the lockdowns never picked up the habit, and never had the opportunity to turn into negative influencers of their younger classmates, he said.

“The pandemic stopped the cycle of new kids coming in and being recruited to drug use,” Miech said.

Mental health may also be a factor. There were increased reports of depression and anxiety in kids after the pandemic began. Depression is often associated with substance use, but some people with depression and anxiety are very wary of messing with drugs, said Dr. Duncan Clark, a University of Pittsburgh psychiatrist who researches substance use in kids.

“Some teens with anxiety are worried about the effects of substances. They may also be socially inhibited and have less opportunity to use drugs,” Clark said. “It’s a complicated relationship.”

PARIS — France connected the Flamanville 3 nuclear reactor to its grid on Saturday morning, state-run operator EDF said, in the first addition to the country’s nuclear power network in 25 years.

The reactor, which began operating in September ahead of the grid connection, is going online 12 years later than originally planned and at a cost of about $13 billion — four times the original budget.

“EDF teams have achieved the first connection of the Flamanville EPR to the national grid at 11:48 a.m. The reactor is now generating electricity,” EDF said in a statement.

The Flamanville 3 European Pressurized Reactor is France’s largest at 1.6 gigawatts and one of the world’s biggest, along with China’s 1.75 GW Taishan reactor, which is based on a similar design, and Finland’s Olkiluoto.

It is the first to be connected to the grid since COVAX 2 in 1999 but is being brought into service at a time of sluggish consumption, with France exporting a record amount of electricity this year.

EDF is planning to build six new reactors to fulfill a 2022 pledge made by President Emmanuel Macron as part of the country’s energy transition plans, although questions remain around the funding and timeline of the new projects.

TORONTO — Scientists have long known that light can sometimes appear to exit a material before entering it — an effect dismissed as an illusion caused by how waves are distorted by matter.

Now, researchers at the University of Toronto, through innovative quantum experiments, say they have demonstrated that “negative time” isn’t just a theoretical idea, it exists in a tangible, physical sense, deserving closer scrutiny.

The findings, yet to be published in a peer-reviewed journal, have attracted both global attention and skepticism.

The researchers emphasize that these perplexing results highlight a peculiar quirk of quantum mechanics rather than a radical shift in our understanding of time.

“This is tough stuff, even for us to talk about with other physicists. We get misunderstood all the time,” said Aephraim Steinberg, a University of Toronto professor specializing in experimental quantum physics.

While the term “negative time” might sound like a concept lifted from science fiction, Steinberg defends its use, hoping it will spark deeper discussions about the mysteries of quantum physics.

Years ago, the team began exploring interactions between light and matter.

When light particles, or photons, pass through atoms, some are absorbed by the atoms and later re-emitted. This interaction changes the atoms, temporarily putting them in a higher-energy or “excited” state before they return to normal.

In research led by Daniela Angulo, the team set out to measure how long these atoms stayed in their excited state.

“That time turned out to be negative,” Steinberg said, meaning a duration less than zero.

To visualize this concept, imagine cars entering a tunnel: Before the experiment, physicists recognized that while the average entry time for 1,000 cars might be, for example, noon, the first cars could exit a little sooner, say 11:59 a.m. This result was previously dismissed as meaningless.

What Angulo and colleagues demonstrated was akin to measuring carbon monoxide levels in the tunnel after the first few cars emerged and finding that the readings had a minus sign in front of them.

The experiments, conducted in a cluttered basement laboratory bristling with wires and aluminum-wrapped devices, took over two years to optimize. The lasers used had to be carefully calibrated to avoid distorting the results.

Still, Steinberg and Angulo are quick to clarify: No one is claiming time travel is a possibility.

“We don’t want to say anything traveled backward in time,” Steinberg said. “That’s a misinterpretation.”

The explanation lies in quantum mechanics, where particles like photons behave in fuzzy, probabilistic ways rather than following strict rules.

Instead of adhering to a fixed timeline for absorption and re-emission, these interactions occur across a spectrum of possible durations, some of which defy everyday intuition.

Critically, the researchers say, this doesn’t violate Einstein’s theory of special relativity, which dictates that nothing can travel faster than light. These photons carried no information, sidestepping any cosmic speed limits.

The concept of “negative time” has drawn both fascination and skepticism, particularly from prominent voices in the scientific community.

German theoretical physicist Sabine Hossenfelder, for one, criticized the work in a YouTube video viewed by more than 250,000 people, noting, “The negative time in this experiment has nothing to do with the passage of time — it’s just a way to describe how photons travel through a medium and how their phases shift.”

Angulo and Steinberg pushed back, arguing that their research addresses crucial gaps in understanding why light doesn’t always travel at a constant speed.

Steinberg acknowledged the controversy surrounding their paper’s provocative headline but pointed out that no serious scientist has challenged the experimental results.

“We’ve made our choice about what we think is a fruitful way to describe the results,” he said, adding that while practical applications remain elusive, the findings open new avenues for exploring quantum phenomena.

NEW YORK — The U.S. flu season is under way, with cases surging across much of the country, health officials said Friday. 

The Centers for Disease Control and Prevention noted sharp increases in several measures, including lab tests and emergency room visits. 

“It’s been increasing at a pretty steady pace now for the past several weeks. So yeah, we are certainly in flu season now,” said the CDC’s Alicia Budd. 

Thirteen states reported high or very high levels of flu-like illness last week, about double from the week before. One is Tennessee, where a sickness spike is hitting the Nashville area, said Dr. William Schaffner, an infectious diseases expert at Vanderbilt University. 

“Flu has been increasing, but just this last week has exploded,” Schaffner said. He noted that in a local clinic that serves as an indicator of illness trends, as many as a quarter of the patients have flu symptoms. 

Louisiana is another early hot spot. 

“Just this week is really that turning point where people are out because of the flu,” said Dr. Catherine O’Neal, an infectious diseases doctor at the largest private hospital in the state, Our Lady of the Lake Regional Medical Center in Baton Rouge. “You hear parents saying, ‘I can’t come to work because of the flu’ and ‘Where can I get a flu test?’” 

There are a number of bugs that cause fever, cough, sore throat and other flu-like symptoms. One is COVID-19. Another is RSV, or respiratory syncytial virus, which is a common cause of cold-like symptoms but can be dangerous for infants and the elderly. 

The most recent CDC data show COVID-19 hospitalizations have been declining since summer. COVID-19 activity is moderate nationally, but high in the Midwest, according to CDC wastewater data. 

RSV hospitalizations started rising before flu did and now show signs of possibly leveling off, but they remain a little more common than admissions for flu. Overall, RSV activity is low nationally, but high in the South, the wastewater data show. 

The CDC called the start of flu season based on several indicators, including lab results for patients in hospitals and doctor’s offices, and the percentage of emergency department visits that had a discharge diagnosis of flu. 

No flu strain seems to be dominant, and it’s too early in the season to know how good a match the flu vaccine will be, Budd said. 

Last winter’s flu season was considered “moderate” overall, but it was long — 21 weeks — and the CDC estimated there were 28,000 flu-related deaths. It was unusually dangerous for children, with 205 pediatric deaths reported. That was the highest number ever reported for a conventional flu season. 

The long season was likely a factor, Budd said. Another factor was a lack of flu vaccinations. Among the children who died who were old enough for flu vaccinations — and for whom their vaccination status was known — 80% were not fully vaccinated, according to the CDC. 

Vaccination rates for children are even lower this year. As of Dec. 7, about 41% of adults had received a flu vaccination, similar to the rate at the same point last year. The percentage is the same for kids, but for them that’s a drop from a year ago, when 44% were vaccinated against the flu, according to CDC data. 

Vaccination rates are lower still against COVID-19, with about 21% of adults and 11% of children up to date. 

Flu experts suggest everyone get vaccinated, especially as people prepare to attend holiday gatherings where respiratory viruses can spread widely. 

“All those gatherings that are so heartwarming and fun and joyous are also an opportunity for this virus to spread person to person,” Schaffner said. “It’s not too late to get vaccinated.”
