U.S. scientists have achieved net energy gain in a fusion reaction for the second time since December, the Lawrence Livermore National Laboratory said on Sunday.

Scientists at the California-based lab repeated the fusion ignition breakthrough in an experiment in the National Ignition Facility (NIF) on July 30 that produced a higher energy yield than in December, a Lawrence Livermore spokesperson said.

Final results are still being analyzed, the spokesperson added.

Lawrence Livermore achieved a net energy gain in a fusion experiment using lasers on Dec. 5, 2022. The scientists focused a laser on a target of fuel to fuse two light atoms into a denser one, releasing the energy.

That experiment briefly achieved what’s known as fusion ignition by generating 3.15 megajoules of energy output after the laser delivered 2.05 megajoules to the target, the Energy Department said.

In other words, it produced more energy from fusion than the laser energy used to drive it, the department said.

The Energy Department called it “a major scientific breakthrough decades in the making that will pave the way for advancements in national defense and the future of clean power.”

Scientists have known for about a century that fusion powers the sun and have pursued developing fusion on Earth for decades. Such a breakthrough could one day help curb climate change if companies can scale up the technology to a commercial level in the coming decades.

Elon Musk said in a social media post that his proposed cage fight with Meta (META.O) CEO Mark Zuckerberg would be live-streamed on social media platform X, formerly known as Twitter. 

The social media moguls have been egging each other into a mixed martial arts cage match in Las Vegas since June.

“Zuck v Musk fight will be live-streamed on X. All proceeds will go to charity for veterans,” Musk said in a post on X early on Sunday morning, without giving any further details.

Earlier on Sunday, Musk had said on X that he was “lifting weights throughout the day, preparing for the fight”, adding that he did not have time to work out so brings the weights to work.

When a user on X asked Musk the point of the fight, Musk responded by saying “It’s a civilized form of war. Men love war.”

Meta did not respond to a Reuters request for comment on Musk’s post. 

The brouhaha began when Musk said in a June 20 post that he was “up for a cage match” with Zuckerberg, who is trained in jiujitsu.

A day later, Zuckerberg, 39, who has posted pictures of matches he has won on his company’s Instagram platform, asked Musk, 51, to “send location” for the proposed throwdown, to which Musk replied “Vegas Octagon”, referring to an events center where mixed martial arts (MMA) championship bouts are held.

Musk then said he would start training if the cage fight took shape.

The tidal wave of artificial intelligence (AI) barrelling toward many professions has generated deep anxiety among workers fearful that their jobs will be swept away — and the mental health impact is rising.

The launch in November 2022 of ChatGPT, the generative AI platform capable of handling complex tasks on command, marked a tech landmark as AI started to transform the workplace.

“Anything new and unknown is anxiety-producing,” Clare Gustavsson, a New York therapist whose patients have shared concerns about AI, told AFP.

“The technology is growing so fast, it is hard to gain sure footing.”

Legal assistants, programmers, accountants and financial advisors are among those professions feeling threatened by generative AI that can quickly create human-like prose, computer code, articles or expert insight.

Goldman Sachs analysts see generative AI impacting, if not eliminating, some 300 million jobs, according to a study published in March.

“I anticipate that my job will become obsolete within the next 10 years,” Eric, a bank teller, told AFP, declining to give his second name.

“I plan to change careers. The bank I work for is expanding AI research.”

Trying to ’embrace the unknown’

New York therapist Meris Powell told AFP of an entertainment professional worried about AI being used in film and television production — a threat to actors and screenwriters that is a flashpoint in strikes currently gripping Hollywood.

“It’s mainly people who are in creative fields who are at the forefront of that concern,” Gustavsson said.

AI is bringing with it a level of apprehension matched by climate change and the Covid-19 pandemic, she contended.

But she said that she tries to get patients to “embrace the unknown” and find ways to use new technology to their advantage.

For one graphic animator in New York, the career-threatening shock came from seeing images generated by AI-infused software such as Midjourney and Stable Diffusion that rivaled the quality of those created by humans.

“People started to realize that some of the skills they had developed and specialized in could possibly be replaced by AI,” she told AFP, adding she had honed her coding skills, but now feels even that has scant promise in an AI world.

“I’ll probably lean into more of a management-level role,” she said. “It’s just hard because there are a lot less of those positions.

“Before I would just pursue things that interested me and skills that I enjoy. Now I feel more inclined to think about what’s actually going to be useful and marketable in the future.”

Peter Vukovic, who has been chief technology officer at several startups, expects just one percent or less of the population to benefit from AI.

“For the rest, it’s a gray area,” Vukovic, who lives in Bosnia, said. “There is a lot of reason for 99 percent of people to be concerned.”

AI is focused on efficiency and making money, but it could be channeled to serve other purposes, Vukovic said.

“What’s the best way for us to use this?” he asked. “Is it really just to automate a bunch of jobs?”

During Europe’s heat wave last month, Floriana Peroni’s vintage clothing store had to close for a week. A truck of rented generators blocked her door as they fed power to the central Roman neighborhood hit by a blackout as temperatures surged. The main culprit: air conditioning. 

The period — in which temperatures hit 40 degrees Celsius (104 degrees Fahrenheit) — coincided with peak electricity use that came close to Italy’s all-time high, hitting a peak load of more than 59 gigawatts on July 19. That neared a July 2015 record. 

Intensive electricity use knocked out the network not only near the central Campo de Fiori neighborhood, where Peroni operates her shop, but elsewhere in the Italian capital. Demand in that second July week surged 30%, correlating to a heat wave that had persisted already for weeks, according to the capital’s electricity company ARETI. 

Like many Romans, Peroni herself does not have AC either in her home or her shop. Rome once could count on a Mediterranean breeze to bring down nighttime temperatures, but that has become an intermittent relief at best. 

“At most, we turn on fans,” Peroni said. “We think that is enough. We tolerate the heat, as it has always been tolerated.” 

In Europe, though, that is starting to change. 

Air conditioning is less a part of the culture in Europe 

Despite holdouts like Peroni, rising global temperatures are dropping air conditioning from luxury to a necessity in many parts of Europe, which long has had a conflicted relationship with energy-sucking cooling systems deemed by many to be an American indulgence. 

Europeans look with disdain at overcooled U.S. buildings, kept to near meat-locker temperatures, where a blast of cold air can shoot across city sidewalks as people come and go, and where extended indoor appointments necessitate a sweater even in the height of summer. 

By contrast, event organizers in Europe may offer hand fans if events are expected to overheat. Shoppers can expect to sweat in under-cooled grocery stores, and movie theaters are not guaranteed to be climate-controlled. Evening diners have typically opted for outside tables to avoid stuffy restaurants, which rarely offer AC. 

To deal with the heat, Italy and Spain typically shut down for several hours after lunch, for a riposo or siesta, and most vacation in August, when many businesses shut down completely so families can enjoy a holiday at the seaside or in the mountains. Italians in particular are happy to abandon overheated art cities to foreign tourists, which reduces the urgency for a home AC investment. 

Still, European AC penetration has picked up from 10% in 2000 to 19% last year, according to the International Energy Agency. That is still well shy of the United States, at around 90%. Many in Europe resist due to cost, concern about environmental impact and even suspicions of adverse health impacts from cold air currents, including colds, a stiff neck, or worse. 

Cooling systems remain rare in Nordic countries and even Germany, where temperatures can nudge above 30 degrees (into the 90s Fahrenheit) for extended periods. 

But even those temperate climates may cross the threshold of discomfort if temperatures increase beyond 1.5 degrees C to 2 degrees C, according to a new study by the University of Cambridge. In that scenario, people living in northern climes like Britain, Norway, Finland and Switzerland will face the greatest relative increase in uncomfortably hot days. 

Nicole Miranda, one of the study’s authors, said their estimate, which would mean surpassing the international goal of limiting future warming to 1.5 degrees Celsius above pre-industrial times, are conservative. 

“They don’t take into account the urban island effects,” she said, when cities are unable to cool at night and surfaces become radiators. “From a scientific point of view, if we all run to the go-to solution, which is air conditioning, we are going to get into a different type of problem, because there is high energy consumption and high carbon emissions related to air conditioning.” 

Cities should consider less intensive solutions, like shading buildings, and incorporating cooling bodies of water, she said. She also advocated a trend toward cooling individuals, instead of spaces, using personal devices like ice packs in jackets or high-tech textiles that dissipate body heat more efficiently. 

Growing — if reluctant — demand 

In Italy, sales of air conditioning units grew from 865,000 a year in 2012 to 1.92 million in 2022, mostly for business and not residential use, with growth reported in the first quarter of this year, according to the industry association Assoclima. Most are split heat air pump systems, which can heat spaces in the winter, which Assoclima said can reduce gas consumption as prices spike during the war in Ukraine. That dual use attracts consumers. 

France, with a slightly larger population, is showing more resistance, selling 1 million units a year. Air conditioning was rare in France until a 2003 heat wave killed thousands, mainly among the elderly. Still, most private homes and apartments there aren’t air conditioned, and many restaurants and other businesses aren’t either. Businesses with AC will often advertise to attract customers on hot days. 

AC aversion persists, both among French conservatives who see it as a frivolous American import and French people on the left who see it as environmentally irresponsible. 

Cécile de Munck and Aude Lemonsu, meteorologists at France’s national weather service, warned this summer that if the number of AC units doubles in Paris by 2030, the city temperature would rise by 2 degrees Celsius (3.6 degrees Fahrenheit) because of heat released by the pump systems. 

Despite the concerns over energy costs, air conditioning is rapidly conquering homes in Spain, a country that traditionally bent towards the use of fans and drawing heavy blinds, a very Spanish fixture. A study by Ca’ Foscari University projects that half of Spanish households will have AC by 2040, up from just 5% in 1990. 

With the cooler indoor air come disputes as neighbors complain about noise from external units. That means problems for Spain’s real estate managers. “Some people can’t open a window because they get a puff of fire,” said Pablo Abascal, president of Spain’s council of real estate managers. “With the increase of AC systems in homes, many buildings will soon have nowhere to place the devices.” 

Air conditioning and cooling was found to be key for older populations in extreme heat, reducing strain on cardiovascular functions in a heat wave of 37 degrees Celsius (99 degrees Fahrenheit), according to a study at the University of Ottawa in Canada. But even in countries like Cyprus, where heat waves of 40 degree Celsius have become the norm, the sustained use of AC isn’t an affordable option for many elderly people living on fixed incomes. 

Many on the Mediterranean island nation restrict usage to the hottest times of day, sometimes confining themselves to a single room. 

“Undoubtedly, this scenario significantly impacts their mental well-being as well,” said Demos Antoniou, director of the Cyprus Third Age Observatory, a seniors-rights group. “The prevailing fear is that refraining from using air conditioners could potentially lead to heat stroke.” 

At 83, Angeliki Vassiliou thinks both about her energy bill and future generations before she hits the “on” button. 

“There’s no sense in wasting energy. Waste is unfair,” Vassiliou said. “Waste of any resource is wrong, because what would happen to our planet because of all this waste?”

India’s latest space mission entered the moon’s orbit on Saturday ahead of the country’s second attempted lunar landing, as its space program seeks to reach new heights.

The world’s most populous nation has a comparatively low-budget aerospace program that is rapidly closing in on the milestones set by global space powers.

Only Russia, the United States and China have previously achieved a controlled landing on the lunar surface.

The Indian Space Research Organization confirmed that Chandrayaan-3, which means moon craft in Sanskrit, had been “successfully inserted into the lunar orbit,” more than three weeks after its launch.

If the rest of the current mission goes to plan, the mission will safely touch down near the moon’s little-explored south pole between Aug. 23 and 24.

India’s last attempt to do so ended in failure four years ago, when ground control lost contact moments before landing.

Developed by ISRO, Chandrayaan-3 includes a lander module named Vikram, which means valor in Sanskrit, and a rover named Pragyan, the Sanskrit word for wisdom.

The mission comes with a price tag of $74.6 million, far smaller than those of other countries, and a testament to India’s frugal space engineering.

Experts say India can keep costs low by copying and adapting existing space technology. It also has an abundance of highly skilled engineers who earn a fraction of their foreign counterparts’ wages.

The Chandrayaan-3 spacecraft has taken much longer to reach the moon than the manned Apollo missions of the 1960s and 1970s, which arrived in a matter of days.

The Indian rocket used is much less powerful than the United States’ Saturn V. Instead, the probe orbited Earth five or six times elliptically to gain speed, before being sent on a monthlong lunar trajectory.

If the landing is successful, the rover will roll off Vikram and explore the nearby lunar area, gathering images to be sent back to Earth for analysis.

The rover has a mission life of one lunar day or 14 Earth days.

ISRO chief S. Somanath has said his engineers carefully studied data from the last failed mission and have worked to fix the glitches.

India’s space program has grown considerably in size and momentum since it first sent a probe to orbit the moon in 2008.

In 2014, it became the first Asian nation to put a satellite into orbit around Mars, and three years later, the ISRO launched 104 satellites in a single mission.

The ISRO’s Gaganyaan (“Skycraft”) program is slated to launch a three-day manned mission into Earth’s orbit by next year.

India is also working to boost its 2% share of the global commercial space market by sending private payloads into orbit for a fraction of the cost of competitors.

The World Bank is aiming to help fund construction of 1,000 mini solar power grids in Africa’s biggest economy Nigeria in partnership with the government and private sector, the lender’s president Ajay Banga said Saturday.

Nigeria, with a population of more than 200 million people, has installed power generation capacity of 12,500 megawatts, or MW, but it produces a fraction of that, leaving millions of households and businesses reliant on petrol and diesel generators.

Mini grids, made up of small-scale electricity generating units, typically range in size from a few kilowatts to up to 10 MW, enough to power about 200 households.

Speaking during a visit to a mini grid site on the outskirts of the capital Abuja, Banga told reporters that nearly 150 mini grids had been built, partly funded by the World Bank, to bring power to communities without access to electricity.

“We are putting another 300 in, but our ambition with the government is to go all the way to 1,000. We’re talking about hundreds of millions of dollars that are being invested,” said Banga, without giving a timeline.

“Now the idea is not for the World Bank to be the only person putting the money. We put part of the money like a subsidy.”

World Bank data shows that in sub-Saharan Africa, 568 million people still lack access to electricity. Globally, nearly 8 out of 10 people without electricity live in Africa.

Somalia reopened the National Blood Bank Saturday for the first time in more than 30 years, in a significant move to address the shortage of blood supplies and save lives.

Somalia Prime Minister Hamza Abdi Barre, who inaugurated the fresh start for the center in Mogadishu, said it’s a crucial achievement for his nation, which has been grappling with frequent disasters and violent incidents that require adequate blood supplies.

The country’s health minister, Dr. Ali Haji Adam, told VOA the revival of the center signifies a turning point in the country’s health care system.

“With the reopening of the national blood bank, we can now adequately address the overwhelming demand for blood in emergency situations and enhance the chances of saving precious lives.” Adam said.

The minister said the center will have the capacity to store hundreds of thousands of blood donations, all made by the public.

“In the past, when tragic accidents like the Zobe 1 and Zobe 2 explosions occurred in 2017 and in 2022, the public rushed to donate blood, but unfortunately there was no adequate storage facility to store the donated blood. Today that changes,” Adam explained.

The health minister highlighted the critical impact of the lack of access to safe blood in Somalia, particularly in connection with child mortality.

“The second cause of maternal death during childbirth is bleeding, but with the reopening of [the] blood bank, mothers will have access to this lifesaving resource,” Adam said.

Hospitals across Somalia have faced immense challenges in obtaining sufficient blood supplies.

Medical officials say they are optimistic that the blood bank will not only serve the immediate needs of people injured in accidents and disasters but will also prove beneficial for anemic children in Somalia.

Established in 1976, the national blood bank had not been operating for nearly three decades due to conflicts, leaving the war-torn nation without a reliable source of blood for critical medical emergencies.

Rhonda Hicks could have kept working into her 60s. She loved teaching and loved her students in Philadelphia’s public schools. As a Black woman, she took pride in being a role model for many children of color.

But other aspects of the job deteriorated, such as growing demands from administrators over what and how to teach. And when she retires in a few weeks, she will join a disproportionately high number of Black and Hispanic teachers in her state who are leaving the profession.

“I enjoy actually teaching, that part I’ve always enjoyed,” said Hicks, 59. “Sometimes it’s a little stressful. Sometimes the kids can be difficult. But it’s the higher-ups: ‘Do it this way or don’t do it at all.'”

Teachers are leaving jobs in growing numbers, state reports show. The turnover in some cases is highest among teachers of color. A major culprit: stress — from pandemic-era burnout, low pay and the intrusion of politics into classrooms. But the burdens can be heavier in schools serving high-poverty communities that also have higher numbers of teachers of color.

In Philadelphia, a city with one of the highest concentrations of Black residents in the U.S., the proportion of Black teachers has been sliding. Two decades ago, it was about one-third. Last fall, it fell to below 23%, according to district figures.

In the school buildings where Hicks taught, most teachers were white. She said she and other teachers of color were expected to give more of themselves in a district where half the students are Black.

“A lot of times when you see teachers that are saving Black and brown kids on TV, it’s always the white ones,” Hicks said. “There are Black teachers and Hispanic teachers out there that do the same thing in real life, all the time.”

Nationally, about 80% of American public school teachers are white, even though white students no longer represent a majority in public schools. Having teachers who reflect the race of their students is important, researchers say, to provide students with role models who have insight into their culture and life experience.

The departures are undoing some recent success that schools have had in bringing on more Black and Hispanic teachers. Turnover is higher among newer teachers. And researchers have found that teachers of color, who tend to have less seniority, often are affected disproportionately by layoffs.

In Pennsylvania, Black teachers were more than twice as likely to leave the profession as white teachers after the 2021-22 school year, according to a data analysis by Ed Fuller, an education professor at Penn State. Hispanic and multiracial teachers had a similar ratio, of around twice as likely.

Black and Hispanic teachers are more likely to be uncertified or teaching in an underfunded district, all of which is associated with someone leaving the profession at a higher rate, Fuller said.

“They’re in more precarious teaching positions, meaning you’re in a position with less resources and worse working conditions, so you’re more likely to quit no matter who you are,” Fuller said.

Sharif El-Mekki, a former Philadelphia teacher who leads the Center for Black Educator Development, said schools around the country come to him seeking help in recruiting teachers of color. But they don’t have plans to retain them, such as providing opportunities to help shape policies and curricula.

To address the problem, schools can start by ensuring students of color have better experiences in school themselves and offering them opportunities to consider teaching, El-Mekki said. Black teachers also are more likely stay on in school systems that have Black leaders, he said, as well as a culture and approaches to teaching that are anti-racist.

“We need to think about, ‘How are they experiencing my school?'” he said. “If they are having a better experience with us, they are more likely to stay.”

Attrition by teachers of color can vary greatly by state or region. Overall, it has been higher compared with white teachers for two decades, since around the time federal policies began encouraging the closure of schools with low test scores, said Travis Bristol, a professor of teacher education and education policy at the University of California-Berkeley.

In underfunded schools with large populations of Black and Hispanic children, teachers say they can expect more responsibilities, fewer resources and more children troubled by poverty and violence.

“I’m still in the classroom because this is my version of resistance and pushing back on a system that was not designed for folks that look like me and kids that look like me,” said Sofia Gonzalez, a 14-year teacher of Puerto Rican heritage in Chicago-area public schools. “We as teachers of color have to find so much inner strength inside of us to sustain our careers in education.”

The last few years have been a trying stretch for teachers everywhere. They’ve had to navigate COVID-19, a pivot to distance learning and the struggles with misbehavior and mental health that accompanied students’ return to classrooms.

Then there’s the pay: Educators’ salaries have been falling behind their college-educated peers in other professions.

Teachers unions have warned of flagging morale, and there are signs lately that more educators are heading for the exits. Data from at least a handful of states — including Pennsylvania, North Carolina, Texas and Washington — is showing an increase in teacher attrition.

Black teachers reported significantly higher rates of burnout and being significantly more likely to leave their job than white teachers, according to research sponsored by two national teachers unions and published in June by the Rand Corp. think tank.

Chantle Simpson, 36, taught her last day of school this spring in Frisco, Texas, ending her 11-year career as a teacher.

She described an exodus of her fellow teachers of color from the profession amid growing expectations from administrators, who put more work on teachers by repeatedly appeasing demands from parents.

Administrators — including those who are Black or Hispanic — put more pressure on Black and Hispanic teachers, she said.

“They believe we can handle more,” Simpson said. “Because we develop relationships better, the kids understand us more, so they’re more likely to behave for us or do what we ask them to. So we get fitted with the children who are more challenging or have more requirements. It’s crazy.”

That leaves those teachers with less time for the rest of their better-behaved students, Simpson said.

“I always was conflicted by it,” Simpson said. “It’s mixed with praise, but it’s a punishment. ‘Oh, you’re so great at building relationships, the kids really appreciate being with you, they respond to you.’ But at the same time, you’re increasing my workload, you’re increasing the amount of attention I have to give to one child versus my whole class.”

Federal health officials have approved the first pill specifically intended to treat severe depression after childbirth, a condition that affects thousands of new mothers in the U.S. each year.

The Food and Drug Administration on Friday granted approval of the drug, Zurzuvae, for adults experiencing severe depression related to childbirth or pregnancy. The pill is taken once a day for 14 days.

“Having access to an oral medication will be a beneficial option for many of these women coping with extreme, and sometimes life-threatening, feelings,” said Dr. Tiffany Farchione, FDA’s director of psychiatric drugs, in a statement.

Postpartum depression affects an estimated 400,000 people a year, and while it often ends on its own within a couple weeks, it can continue for months or even years. Standard treatment includes counseling or antidepressants, which can take weeks to work and don’t help everyone.

The new pill is from Sage Therapeutics, which has a similar infused drug that’s given intravenously over three days in a medical facility. The FDA approved that drug in 2019, though it isn’t widely used because of its $34,000 price tag and the logistics of administering it.

The FDA’s pill approval is based on two company studies that showed women who took Zurzuvae had fewer signs of depression over a four- to six-week period when compared with those who received a dummy pill. The benefits, measured using a psychiatric test, appeared within three days for many patients.

Sahar McMahon, 39, had never experienced depression until after the birth of her second daughter in late 2021. She agreed to enroll in a study of the drug, known chemically as zuranolone, after realizing she no longer wanted to spend time with her children.

“I planned my pregnancies, I knew I wanted those kids, but I didn’t want to interact with them,” said McMahon, who lives in New York City. She says her mood and outlook started improving within days of taking the first pills.

“It was a quick transition for me just waking up and starting to feel like myself again,” she said.

Dr. Kimberly Yonkers of Yale University said the Zurzuvae effect is “strong,” and the drug likely will be prescribed for women who haven’t responded to antidepressants. She wasn’t involved in testing the drug.

Still, she said, the FDA should have required Sage to submit more follow-up data on how women fared after additional months.

“The problem is we don’t know what happens after 45 days,” said Yonkers, a psychiatrist who specializes in postpartum depression. “It could be that people are well or it could be that they relapse.”

Sage did not immediately announce how it would price the pill, and Yonkers said that’ll be a key factor in how widely it’s prescribed.

Side effects with the new drug are milder than the IV version and include drowsiness and dizziness. The drug was co-developed with fellow Massachusetts pharmaceutical company Biogen.

Both the pill and IV forms mimic a derivative of progesterone, the naturally occurring female hormone needed to maintain a pregnancy. Levels of the hormone can plunge after childbirth.

Sage’s drugs are part of an emerging class of medications dubbed neurosteroids. These stimulate a different brain pathway than older antidepressants that target serotonin, the chemical linked to mood and emotions.

NASA has succeeded in reestablishing full contact with Voyager 2 by using its highest-power transmitter to send an “interstellar shout” that righted the distant probe’s antenna orientation, the space agency said Friday.

Launched in 1977 to explore the outer planets and serve as a beacon of humanity to the wider universe, it is currently more than 19.9 billion kilometers from our planet — well beyond the solar system. 

A series of planned commands sent to the spaceship on July 21 mistakenly caused the antenna to point 2 degrees away from Earth, compromising its ability to send and receive signals and endangering its mission.

The situation was not expected to be resolved until at least Oct. 15 when Voyager 2 was scheduled to carry out an automated realignment maneuver.

But Tuesday, engineers enlisted the help of multiple Earth observatories that form the Deep Space Network to detect a carrier or “heartbeat” wave from Voyager 2, though the signal was still too faint to read the data it carried.

In an update on Friday, NASA’s Jet Propulsion Laboratory (JPL), which built and operates the probe, said it had succeeded in a longshot effort to send instructions that righted the craft.

“The Deep Space Network used the highest-power transmitter to send the command (the 100-kw S-band uplink from the Canberra site) and timed it to be sent during the best conditions during the antenna tracking pass in order to maximize possible receipt of the command by the spacecraft,” Voyager project manager Suzanne Dodd told AFP.

This so-called “interstellar shout” required 18.5 hours traveling at light speed to reach Voyager, and it took 37 hours for mission controllers to learn whether the command worked, JPL said in a statement.

The probe began returning science and telemetry data at 12:29 a.m. Eastern Time on Friday, “indicating it is operating normally and that it remains on its expected trajectory,” JPL added.

‘Golden records’

Voyager 2 left the protective magnetic bubble provided by the sun, called the heliosphere, in December 2018, and is currently traveling through the space between the stars.

Before leaving our solar system, it explored Jupiter and Saturn, and became the first and so far only spacecraft to visit Uranus and Neptune.

Voyager 2’s twin, Voyager 1, was mankind’s first spacecraft to enter the interstellar medium, in 2012, and is currently almost 24 billion kilometers from Earth.

Both carry “Golden Records” — 30-centimeter, gold-plated copper disks intended to convey the story of our world to extraterrestrials.

These include a map of our solar system, a piece of uranium that serves as a radioactive clock allowing recipients to date the spaceship’s launch, and symbols that convey how to play the record.

The contents of the discs, selected for NASA by a committee chaired by legendary astronomer Carl Sagan, include encoded images of life on Earth, as well as music and sounds that can be played using an included stylus.

For now, the Voyagers continue to transmit scientific data to Earth, though their power banks are expected to eventually be depleted sometime after 2025.

They will then continue to wander the Milky Way, potentially for eternity, in silence.

When Clarisse Agbégnénou won her sixth world judo title, confirming the reigning Olympic champion as one of the athletes to watch at next year’s Paris Games, the French star’s smallest but greatest fan was less wild about her mother’s newest gold medal than she was about her breast milk.

After a peckish day of few feeds — because Mom had been busy putting opponents through the wringer — 10-month-old Athéna made amends that night.

“She didn’t let my boobs out of her mouth,” Agbégnénou said. “I was like, ‘Wow, OK.’ I think it was really something for her.”

Breastfeeding and high-performance sports were long an almost impossible combination for top female athletes, torn for decades between careers or motherhood, because having both was so tough.

But that’s becoming less true ahead of the 2024 Olympics, where women will take another step forward in their long march for equality, competing in equal numbers with men for the first time, and with pioneering mothers like Agbégnénou showing that it is possible to breastfeed and be competitive.

They don’t pretend that late-night feeds, broken sleep, pumping milk and having to eat for two people are easy. But some female athletes are also discovering that juggling their careers with the rigors of motherhood can pay off with powerful emotional well-being.

Speaking in an interview with The Associated Press, Agbégnénou said she stunned even herself by coming back so quickly from childbirth to win at the worlds in May, with Athéna in tow and expecting to be fed every few hours.

In training, Agbégnénou would stop for quick feeds when Athéna needed milk, nestling her hungry baby in the folds of her kimono, while other athletes in the judo hall paid them no mind, carrying on with their bouts.

“I was sweating on her, poor baby,” she said. “But she didn’t pay attention. She just wanted to eat.”

Women who have breastfed and carried on competing say that support from coaches and sports administrators is essential. Agbégnénou credits the International Judo Federation for allowing her to take Athéna to competitions. IJF officials sounded out other competitors and coaches about whether the baby was a nuisance for them and were told, “‘No, she was really perfect, we didn’t hear the baby,'” she said.

“It’s amazing,” she said of her peers’ acceptance and support. “They are part of my fight and I am really proud of them.”

As well as Agbégnénou, three other women also asked and were allowed to nurse their babies at IJF World Tour competitions in the past six years, with arrangements made each time that enabled the moms “to care for the child and to not disturb other athletes’ preparation,” said the governing body’s secretary general, Lisa Allan. She says the IJF is now drawing up specific policies for judokas who are pregnant or postpartum because “more and more athletes are continuing their careers whilst balancing having a family.”

The Paris Olympics’ chief organizer, Tony Estanguet, said they’re also exploring the possibility of providing facilities for nursing athletes at the Games.

“They should have access to their children — for the well-being of the mothers and the children,” he said in an AP interview. “The status of athletes who are young mothers needs to evolve a bit. We need to find solutions to perhaps make it easier for these athletes to bring babies” into the Olympic village where athletes are housed.

For some breastfeeding athletes, being a pioneer is part of the kick.

Two-time Olympic rowing champion Helen Glover, now aiming for her fourth Summer Games, gave birth to twins at the start of the COVID-19 outbreak, breastfed them and then came out of what she’d intended to be retirement to compete at the pandemic-delayed Tokyo Games in 2021.

Glover was the first rower to compete for Britain at the Olympics as a mother.

Glover’s eldest, Logan, lost interest in her milk about the time of his first birthday, but twins Kit and Willow kept feeding to 14 months old. She says that mixing her punishing rowing training with long feeds for two babies was “very draining. It was taking every calorie I had.”

“But I could do it because it was my own time and my own choice,” she said.

“Everyone should have the choice,” Glover added. “Our bodies … are sometimes very changed through childbirth and pregnancy and breastfeeding. So the answers are never going to be one-size-fits-all. But I think it’s really exciting that these conversations are even being had.”

For some athletes, Milk Stork has also been a help. The U.S.-based transporter ships working moms’ milk when they’re separated from their babies. It says it shipped milk pumped by athletes who competed at the 2021 Paralympic Games in Tokyo and also transported 21 gallons (80 liters) of milk from coaches, trainers and other support staff at the Olympics that year.

The daughter of British archery athlete Naomi Folkard was just 5½ months old and breastfeeding exclusively when her mother traveled to Tokyo for her fifth and final Olympic Games.

Nursing mothers successfully pushed to be able to take babies to those Olympics, held with social distancing and without full crowds because of the coronavirus pandemic. Rather than put her daughter, Emily, through the ordeal of having to live apart from her, in a Tokyo hotel outside of the athletes’ village, Folkard reluctantly left her behind with a large stock of frozen milk. She built that up over months, pumping into the night so Emily wouldn’t go hungry while she was in Japan.

But that created another problem: Because Folkard’s breasts had become so good at making milk, she had to pump regularly at the Games to stop them from becoming painfully swollen. She threw that milk away.

“I was having to get up in the night and pump just because my supply was so much,” she said. “It wasn’t great for performance preparation really. But I did what I had to do to be there.”

And with each drop, progress.

“There’s still a long way to go, but people are talking about it now. Women aren’t retiring to have children. They’re still competing,” Folkard said.

“I feel like things are changing.”
