sydney — Analysis of more than 25,000 images from divers, tourism operators and recreational boats on Australia’s annual Great Reef Census is getting under way. Now in its fourth year, one of the world’s fastest-growing conservation projects is helping to gauge the health and degradation of the world’s largest coral system, which is suffering from another mass bleaching event.

The Great Reef Census collects a trove of images of what is arguably Australia’s greatest natural treasure.

Each picture can contain vital information about the health of the Great Barrier Reef. Together, the images create a vital evaluation of the state of the ecosystem.

The barrier reef stretches for 2,300 kilometers down Australia’s northeastern coast. It is under increasing threat from global warming, pollution and overfishing, as well as coral-eating crown of thorns starfish.

The surveillance project is urging so-called citizen scientists around the world to help in the analysis of the images. The survey also uses artificial intelligence to scan much of the data.

The public is being asked to analyze the images to see which reefs fared better than others and potentially identify so-called new “key source reefs,” which are those reefs that appear to have escaped the worst of the degradation.

Anyone can help in the effort, said Nicole Senn, impact and engagement lead at Citizens of the Reef, which coordinates the survey.

“Citizen scientists using our A.I assisted platform can actually provide data that is highly comparable in accuracy to a reef expert, and it takes as little as one minute to analyze an image, and the data you are generating helps to prioritize conservation efforts on the reef and identify key source reefs,” she said. “These are healthy reefs that are positioned in a way that they can help nearby reefs recover and this is just one of the many ways your analysis of these images can help.”

The Great Barrier Reef is suffering from another widespread bleaching event.

Scientists say that corals bleach, or turn white, when they are stressed by changes in water temperature, light, or nutrients. In response, the coral expels the symbiotic algae living in their tissues that give them their color and energy, exposing their white skeleton.

Not all bleaching incidents are due to warm water, but experts say the mass bleaching reported on the Great Barrier Reef is caused by a marine heatwave.

Experts say reefs around the world last year and early this year have been affected by high ocean surface temperatures.

Chris Lawson, a data scientist with the Great Reef Census’ Science Committee, told VOA that the situation appears to be dire.

“The latest mass bleaching event has been designated as the fourth global mass bleaching event,” he said. “So, it is not just in Australia, it has been observed globally and by all accounts is the worst one on record in terms of its extent and its severity of bleaching.”

Experts say reefs’ extreme susceptibility to warming sea temperatures makes them one of the world’s ecosystems that is most vulnerable to climate change.

COTONOU, Benin — Benin, Liberia and Sierra Leone launched large-scale malaria vaccine programs on Thursday under an Africa-focused initiative that hopes to save tens of thousands of children’s lives per year across Africa.

The three West African countries are the latest to participate after successful rollouts of routine malaria immunization for children in Burkina Faso, Cameroon, Ghana, Kenya and Malawi, the global vaccine alliance GAVI said in a statement.

The World Health Organization-approved vaccine is meant to work alongside existing tools such as bed nets to combat malaria, which in Africa kills nearly half a million children under the age of 5 each year.

“This introduction … will help save lives and offer relief to families, communities and hard-pressed health systems,” said Aurelia Nguyen, GAVI chief program officer.

Benin has 215,900 doses of the vaccine, which will be available to children from around 5 months old, according to GAVI.

Sierra Leone has 550,000 doses and neighboring Liberia has 112,000 doses, it said.

At the official launch in Benin, which took place in the town of Allada, some 54 kilometers from the country’s largest city, Cotonou, 25 children received the vaccine.

“I came to have my children vaccinated against malaria. It’s important to me because when children get this malaria disease, we spend a lot of money,” said Victoire Fagbemi, a 41-year-old mother of four.

Another mother, Victoire Boko, who had her 10-month-old child vaccinated at the launch, said the health minister’s explanations about the vaccine in the local Fon language had allayed any anxieties she had about its safety. “When I get home, I will share the information … with my neighbors and friends,” she said on the sidelines of the launch.

The African region is home to 11 countries that carry approximately 70% of the global burden of malaria, according to GAVI.

MIGORI, Kenya — As the coffin bearing the body of Rosebella Awuor was lowered into the grave, heart-wrenching sobs from mourners filled the air. Her sister Winnie Akinyi, the guardian to Awuor’s orphaned son, fell to the ground, wailing. 

It was the latest of five deaths in this family attributed to malaria. The disease is common in Kenya, and it is preventable and curable, but poverty makes it deadly for those who can’t afford treatment. 

In the family’s compound in the western county of Migori, three other graves are visible, that of Awuor’s husband and their other two children who died from malaria before age 2. 

Awuor, 31, fell ill in December and lost her five-month pregnancy before succumbing to malaria. Her 11-year-old son is the family’s only survivor. 

Malaria is still a significant public health challenge in Kenya, though some progress may be coming. Parts of Kenya participated in an important pilot of the world’s first malaria vaccine, with a reported drop in deaths for children under 5. Kenya’s health ministry hasn’t said when the vaccine will be widely available. 

The biggest impact is felt in regions characterized by high temperatures like Kenya’s Indian Ocean coast, and places with high rainfall like the western region near Lake Victoria. 

Kenya had an estimated 5 million malaria cases and more than 12,000 deaths reported in 2022, according to the World Health Organization. The WHO has declared April 25 as World Malaria Day. 

Most of those affected are children under 5 and pregnant women. 

New approaches needed

Kenya continues to combat malaria with traditional methods such as distributing bed nets that are treated with insecticides, spraying breeding areas, and promoting early diagnosis and treatment, but experts say progress against the disease with those approaches has plateaued. 

Public health expert Dr. Willis Akhwale, special adviser for the Kenya End Malaria Council, said the COVID-19 pandemic slowed the distribution of drugs and treatment. 

He said innovative treatment methods are needed in the wake of drug-resistant cases reported in parts of Africa. 

“We need to start looking at investments in new-generation medicines. That should then be able to counter any resistance in [the] foreseeable future,” he said. 

Akhwale said other needs include more funding and logistical support. 

“In Kenya, the shortfall in terms of the need is almost $52 million, so we need to close that gap,” he said, citing health ministry data. He recommended domestic funding and private sector support amid donor fatigue with crises around the world. 

Wilson Otieno has been admitted to a hospital three times for malaria and has received outpatient treatment countless times. It’s expensive for the 33-year-old accountant and father in the lakeside city of Kisumu. 

Malaria is never “pocket friendly,” he said. 

Some progress has been made with local manufacturing of crucial medication. 

The Kenya-based Universal Corporation Limited last year received the WHO’s approval to produce an antimalarial drug known as Spaq, a combination of sulfadoxine-pyrimethamine plus amodiaquine. 

The approval was an important step in Africa’s capacity to make lifesaving medications, a new focus for governments and public health officials after vulnerabilities were exposed by the COVID-19 pandemic. Africa relies heavily on drug imports. 

“It will really help in lowering the dependency for imports as we saw during the COVID era, where whatever was being imported actually had huge supply disruptions,” said Palu Dhanani, the founder and managing director of UCL. 

If you don’t get the right medicine at the right time, malaria can cause unnecessary deaths, Dhanani said.

Paris, France — World wine production dropped 10 percent last year, the biggest fall in more than six decades, because of “extreme” climate changes, the body that monitors the trade said Thursday.  

“Extreme environmental conditions” including droughts, fires and other problems with climate were mostly to blame for the drastic fall, said the International Organization of Vine and Wine, or OIV, that covers nearly 50 wine-producing countries.  

Australia and Italy suffered the worst, with 26 and 23 percent drops. Spain lost more than a fifth of its production. Harvests in Chile and South Africa were down by more than 10 percent. 

The OIV said the global grape harvest was the worst since 1961, and worse even than its early estimates in November. 

In further bad news for winemakers, customers drank 3 percent less wine in 2023, the French-based intergovernmental body said.  

Director John Barker highlighted “drought, extreme heat and fires, as well as heavy rain causing flooding and fungal diseases across major northern and southern hemisphere wine-producing regions.” 

Although he said climate problems were not solely to blame for the drastic fall, “The most important challenge that the sector faces is climate change.  

“We know that the grapevine, as a long-lived plant cultivated in often vulnerable areas, is strongly affected by climate change,” he added.  

France bucked the falling harvest trend, with a 4 percent rise, making it by far the world’s biggest wine producer.

Less wine being drunk

Wine consumption last year was, however, at its lowest level since 1996, confirming a fall off over the last five years, according to the figures.  

The trend is partly due to price increases caused by inflation and a sharp fall in wine drinking in China — down a quarter — due to its economic slowdown. 

The Portuguese, French and Italians remain the world’s biggest wine drinkers per capita. 

Barker said the underlying decrease in consumption is being “driven by demographic and lifestyle changes. But given the very complicated influences on global demand at the moment,” it is difficult to know whether the fall will continue. 

 “What is clear is that inflation is the dominant factor affecting demand in 2023,” he said. 

Land given over to growing grapes to eat or for wine fell for the third consecutive year to 7.2 million hectares.  

But India became one of the global top 10 grape producers for the first time with a 3 percent rise in the size of its vineyards.  

France, however, has been pruning its vineyards back slightly, with its government paying winemakers to pull up vines or to distill their grapes.  

The collapse of the Italian harvest to its lowest level since 1950 does not necessarily mean there will be a similar contraction there, said Barker.  

Between floods and hailstones, and damp weather causing mildew in the center and south of the country, the fall was “clearly linked to meteorological conditions,” he said.

WASHINGTON — U.S. President Joe Biden was in Syracuse, New York, Thursday to tout a deal to provide memory chip maker Micron Technology with $6.1 billion in federal grants to support the firm in building factories in the states of New York and Idaho.

“We’re bringing advanced chip manufacturing back to America after 40 years,” Biden said Thursday. He said the funding, paired with a $125 billion investment from Micron, represents the “single biggest private investment ever in history of these two states.”

The investment will support the construction of two plants in Clay, a suburb of Syracuse, New York, and one in Boise, Idaho. The grant will unleash “$50 billion in private investment by 2030 as the first step towards Micron’s investment of up to $125 billion across both states over the next two decades,” the White House said in a statement.

The deal was announced last week by Senate Majority Leader Chuck Schumer, a Democrat from New York, who personally lobbied Micron to invest in his state. It’s the latest in a series of awards given by the administration, intended to shore up domestic production of advanced semiconductors using funds from the CHIPS and Science Act of 2022. The aim is to boost domestic manufacturing and reduce reliance on chip supplies from China and Taiwan.

This investment will “supercharge Micron to build the most advanced memory chip factory in the world, Schumer said Thursday. “America’s future will be built in Syracuse, not in Shanghai.”

The administration recently awarded Samsung, Taiwan Semiconductor, Intel, GlobalFoundries, Microchip Technology, and BAE Systems, more than $29 billion in federal grants for chipmaking investments. It’s part of an effort to catch up in the global semiconductor manufacturing race currently dominated by China, Taiwan and South Korea.

The U.S. share of global semiconductor manufacturing capacity has decreased from 37% in 1990 to 12% today, largely because other governments have offered manufacturing incentives and invested in research to strengthen domestic chipmaking capabilities, according to the Semiconductor Industry Association.

To address such stiff foreign competition, the $280 billion bipartisan CHIPS and Science Act offers $52 billion in incentives for domestic semiconductor production and research, as well as an investment tax credit for semiconductor manufacturing.

Manufacturing revival

The announcements are part of the economic vision the president is offering to voters in his re-election bid – that he is working to create a manufacturing revival in the country, including in Republican-controlled districts such as where the Micron plant will be located.

“Micron’s total investment will be the largest private investment in New York and Idaho’s history, and will create over 70,000 jobs, including 20,000 direct construction and manufacturing jobs and tens of thousands of indirect jobs,” the White House said.

Ahead of the November presidential election, Biden’s strategy appears to be to announce investments in manufacturing facilities in Georgia, Idaho, North Carolina and Ohio, states where Democrats lack a strong foothold.

It is not clear whether the approach will succeed as voters will not immediately feel the effects. The initial phase of the Micron project, for example, would see the first plant opened in 2028 and the second in 2029.

Meanwhile, voters are concerned about high inflation, and dislike Biden’s economic job performance. A recent Reuters/Ipsos poll shows 34% of respondents approving of Biden’s approach on the economy, compared to 41% who favor the approach of former president Donald Trump, the presumptive Republican nominee.

Still, Biden’s trip to New York is an opportunity for him to celebrate another victory following a string of good news for the president. On Wednesday, he secured the endorsement of the North America’s Building Trades Unions and signed a $95.3 billion aid package for Ukraine, Israel and Taiwan after months of congressional gridlock.

washington — The U.S. Federal Communications Commission voted 3-2 on Thursday to reinstate landmark net neutrality rules and reassume regulatory oversight of broadband internet rescinded under former President Donald Trump. 

The commission voted along party lines to finalize a proposal first advanced in October to reinstate open internet rules adopted in 2015 and re-establish the commission’s broadband authority. 

FCC Chairwoman Jessica Rosenworcel said the agency “believes every consumer deserves internet access that is fast, open, and fair.” 

“The last FCC threw this authority away and decided broadband needed no supervision,” she said. 

Net neutrality refers to the principle that internet service providers should enable access to all content and applications regardless of the source, and without favoring or blocking particular products or websites. 

The FCC said it was also using its authority to order the U.S. units of China Telecom, China Unicom and China Mobile to discontinue broadband internet access services in the United States.  

Rosenworcel noted the FCC has taken similar actions against Chinese telecom companies in the past using existing authority. 

Reinstating the net neutrality rules has been a priority for President Joe Biden, who signed a July 2021 executive order encouraging the FCC to reinstate net neutrality rules adopted under Democratic President Barack Obama. 

Democrats were stymied for nearly three years because they did not take majority control of the five-member FCC until October. 

Under Trump, the FCC had argued the net neutrality rules were unnecessary, blocked innovation and resulted in a decline in network investment by internet service providers, a contention disputed by Democrats. 

The U.S. Chamber of Commerce criticized the FCC action saying it was “imposing a flawed, pre-television era regulatory structure on broadband” and “will only deter the investments and innovation necessary to connect all Americans.” 

Public interest group Free Press said the vote is a “major victory for the public interest” saying it “empowers the FCC to hold companies like AT&T, Comcast, Spectrum and Verizon accountable for a wide range of harms to internet users across the United States.” 

A group of Republican lawmakers, including House Energy and Commerce Committee Chair Cathy McMorris Rodgers and Senator Ted Cruz, called the plan “an illegal power grab that would expose the broadband industry to an oppressive regulatory regime” giving the agency and states power to impose rate regulation, unbundle obligations and tax broadband internet providers. 

Democrats on the FCC say they will not set rate regulations. 

The Computer & Communications Industry Association, whose members include Amazon.com, Apple, Alphabet and Meta Platforms, back net neutrality, arguing the rules “must be reinstated to preserve open access to the internet.” 

USTelecom, whose members include AT&T, Verizon and others, called reinstating net neutrality “entirely counterproductive, unnecessary, and an anti-consumer regulatory distraction.” 

Despite the 2017 decision to withdraw the requirement at the federal level, a dozen states now have net neutrality laws or regulations in place. Industry groups abandoned legal challenges to those state requirements in May 2022.

new york — Russia blocked a U.N. Security Council resolution Wednesday reaffirming the need to prevent a nuclear arms race in outer space.

The measure was proposed jointly by the United States, a nuclear power, and Japan, the only nation ever to be attacked with nuclear bombs.

“We have only begun to understand the catastrophic ramifications of a nuclear explosion in space,” said U.S. Ambassador Linda Thomas-Greenfield. “How it could destroy thousands of satellites operated by countries and companies around the world — and wipe out the vital communications, scientific, meteorological, agricultural, commercial and national security services we all depend on.”

The failed text recalled the responsibility of states to comply with the 1967 Outer Space Treaty, which is the basic framework on international space law. It says outer space is to be shared among nations and shall be free of nuclear weapons or other weapons of mass destruction. The treaty also says the moon and other celestial bodies “shall be used exclusively for peaceful purposes,” and astronauts shall be “regarded as the envoys of mankind.”

The proposed resolution also called on states “not to develop nuclear weapons or any other kinds of weapons of mass destruction specifically designed to be placed in orbit around the Earth, or to be installed on celestial bodies, or to be stationed in outer space in any other manner.”

Thomas-Greenfield noted that President Vladimir Putin has said publicly that Russia has no intention of deploying nuclear weapons in space.

“And so, today’s veto begs the question: Why? Why, if you are following the rules, would you not support a resolution that reaffirms them?” she asked. “What could you possibly be hiding? It’s baffling, and it’s a shame.”

Thomas-Greenfield just returned from Japan, where she visited Nagasaki, a city on which the United States dropped one of two atomic bombs at the end of World War II.

“It was a reminder of our profound responsibility to prevent the scourge of war and ensure that no place experiences the horror of nuclear weaponry ever again,” she said.

“Adopting this draft resolution would have been a positive and practical contribution to the promotion of the peaceful use and exploration of outer space,” said Japanese Ambassador Kazuyuki Yamazaki. “If adopted, we could have demonstrated our unity in reaffirming the principle of no placement of any weapons of mass destruction in outer space and in opposing the development of such capabilities.”

The proposed resolution, which had more than 60 co-sponsors, created no new international obligations, but reaffirmed existing ones. It was supported by 13 of the 15 council members. After failing to get an amendment added to it, Russia vetoed it and China abstained.

“Today, our council is once again being involved in a dirty spectacle prepared by the U.S. and Japan,” Russian Ambassador Vassily Nebenzia said. “This is a cynical ploy. We are being tricked.”

He said Moscow wanted a text that would have gone further, banning weapons of any kind in outer space.

China’s new U.N. ambassador, Fu Cong, echoed that, saying the draft needed “other substantive elements.” 

US concerns

In February, U.S. officials said Russia is developing a space-based weapon to attack satellites. They do not believe it would target people or cause destruction on Earth.

Analysts at the Washington-based Safe World Foundation think tank say on their website that Russia is most likely developing a system “that would use a nuclear explosion to create weapons effects, most likely an electromagnetic pulse (EMP), that would in turn disable or destroy satellites.”

There are thousands of satellites in space that run the gamut from sophisticated military purposes to running a car’s GPS or providing television programming.

Although the U.S. resolution was not adopted, Thomas-Greenfield said Washington would continue to pursue bilateral arms control discussions with Russia in good faith.

The U.S. also has concerns about China’s work in space, where officials say they are rapidly developing a range of counterspace weapons and using outer space to strengthen the capabilities of their military forces on Earth.

“Over the last six years they have tripled the number of intelligent surveillance and reconnaissance satellites in orbit, and they have used their space capabilities to improve the lethality, the precision and the range of their terrestrial forces,” said General Stephen Whiting, commander of the U.S. Space Command.

He spoke by phone to regional journalists Wednesday from Tokyo, where he is meeting with allies.

TOKYO — Japan’s first moon lander has survived a third freezing lunar night, Japan’s space agency said Wednesday after receiving an image from the device three months after it landed on the moon.

The Japan Aerospace Exploration Agency said the lunar probe responded to a signal from the earth Tuesday night, confirming it has survived another weekslong lunar night.

Temperatures can fall to minus 170 degrees Celsius during a lunar night and rise to around 100 Celsius during a lunar day. 

The probe, Smart Lander for Investing Moon, or SLIM, reached the lunar surface on Jan. 20, making Japan the fifth country to successfully place a probe on the moon. 

SLIM landed the wrong way up with its solar panels initially unable to see the sun, and had to be turned off within hours, but powered on when the sun rose eight days later.

SLIM, which was tasked with testing Japan’s pinpoint landing technology and collecting geological data and images, was not designed to survive lunar nights.

JAXA said on the social media platform X that SLIM’s key functions are still working despite repeated harsh cycles of temperature changes. The agency said it plans to closely monitor the lander’s deterioration. 

Scientists are hoping to find clues about the origin of the moon by comparing the mineral compositions of moon rocks and those of Earth.

The message from SLIM came days after NASA restored contact with Voyager 1, the farthest space probe from Earth, which had been sending garbled data back for months.

An U.S. lunar probe developed by a private space company announced termination of its operation a month after its February landing, while an Indian moon lander failed to establish communication after touchdown in 2023.
