FORT LAUDERDALE, Fla. — South Florida researchers trying to prevent predatory fish from devouring laboratory-grown coral are grasping at biodegradable straws in an effort to restore what some call the rainforest of the sea.

Scientists around the world have been working for years to address the decline of coral reef populations. Just last summer, reef rescue groups in South Florida and the Florida Keys were trying to save coral from rising ocean temperatures. Besides working to keep existing coral alive, researchers have also been growing new coral in labs and then placing them in the ocean.

But protecting the underwater ecosystem that maintains more than 25% of all marine species is not easy. Even more challenging is making sure that coral grown in a laboratory and placed into the ocean doesn’t become expensive fish food.

Marine researcher Kyle Pisano said one problem is that predators like parrot fish attempt to bite and destroy the newly transplanted coral in areas like South Florida, leaving them with less than a 40% survival rate. With projects calling for thousands of coral to be planted over the next year and tens of thousands of coral to be planted over the next decade, the losses add up when coral pieces can cost more than $100 each.

Pisano and his partner, Kirk Dotson, have developed the Coral Fort, claiming the small biodegradable cage that’s made in part with drinking straws boosts the survival rate of transplanted coral to over 90%.

“Parrot fish on the reef really, really enjoy biting a newly transplanted coral,” Pisano said. “They treat it kind of like popcorn.”

Fortunately the fish eventually lose interest in the coral as it matures, but scientists need to protect the coral in the meantime. Stainless steel and PVC pipe barriers have been set up around transplanted coral in the past, but those barriers needed to be cleaned of algae growth and eventually removed.

Pisano had the idea of creating a protective barrier that would eventually dissolve, eliminating the need to maintain or remove it. He began conducting offshore experiments with biodegradable coral cages as part of a master’s degree program at Nova Southeastern University. He used a substance called polyhydroxyalkanoate, a biopolymer derived from the fermentation of canola oil. PHA biodegrades in ocean, leaving only water and carbon dioxide. His findings were published last year.

The coral cage consists of a limestone disc surrounded by eight vertical phade brand drinking straws, made by Atlanta-based WinCup Inc. The device doesn’t have a top, Pisano said, because the juvenile coral needs sunlight and the parrot fish don’t generally want to position themselves facing downward to eat.

Dotson, a retired aerospace engineer, met Pisano through his professor at Nova Southeastern, and the two formed Reef Fortify Inc. to further develop and market the patent-pending Coral Fort. The first batch of cages were priced at $12 each, but Pisano and Dotson believe that could change as production scales up.

Early prototypes of the cage made from phade’s standard drinking straws were able to protect the coral for about two months before dissolving in the ocean, but that wasn’t quite long enough to outlast the interest of parrot fish. When Pisano and Dotson reached out to phade for help, the company assured them that it could make virtually any custom shape from its biodegradable PHA material.

“But it’s turning out that the boba straws, straight out of the box, work just fine,” Dotson said.

Boba straws are wider and thicker than normal drinking straws. They’re used for a tea-based drink that includes tapioca balls at the bottom of the cup. For Pisano and Dotson, that extra thickness means the straws last just long enough to protect the growing coral before harmlessly disappearing.

Reef Fortify is hoping to work with reef restoration projects all over the world. The Coral Forts already already being used by researchers at Nova Southeastern and the University of Miami, as well as Hawaii’s Division of Aquatic Resources.

Rich Karp, a coral researcher at the University of Miami, said they’ve been using the Coral Forts for about a month. He pointed out that doing any work underwater takes a great deal of time and effort, so having a protective cage that dissolves when it’s no longer needed basically cuts their work in half.

“Simply caging corals and then removing the cages later, that’s two times the amount of work, two times the amount of bottom time,” Karp said. “And it’s not really scalable.”

Experts say coral reefs are a significant part of the oceanic ecosystem. They occupy less than 1% of the ocean worldwide but provide food and shelter to nearly 25 percent of sea life. Coral reefs also help to protect humans and their homes along the coastline from storm surges during hurricanes.

the white house — Preparations take months. No detail is overlooked, for this is perhaps the most evolved form of diplomacy: the state dinner.

As first lady Jill Biden prepares Wednesday to host her fifth state dinner, for Japan’s leader, she made it clear that every aesthetic detail — from the crystal on the tables, to the food on the White House china, the decor in the State Dining Room, the music and the fashion — drips with diplomatic significance. This dinner, she said in her preview of the event, makes frequent reference to Washington’s famous cherry trees, a gift from Japan more than a century ago.

“As guests sit among the field of flowers, glass and silk butterflies from both our countries will dance over the tables, their graceful flight a reminder that as our nations navigate the winds of change, we do so together as partners in peace and prosperity,” she said.

The White House Historical Association lays out the high stakes, saying a state dinner “showcases global power and influence and sets the tone for the continuation of dialogue between the president and the visiting head of state.”

Roxanne Roberts, a style writer for The Washington Post who has covered state dinners for more than 30 years, likens the dinner to “the frosting on an already-baked cake.”

“The state dinner is the least important part of a state visit, but it’s the thing that gets the most attention,” she told VOA. “… And it sends a signal to not only the government of that country, but the people of that country that you’re important to us. We care about you.”

That’s reflected in the numbers. Records journalists requested from the State Department, which foots the bill, show that Obama-era dinners cost U.S. taxpayers more than $500,000 each. More recent dinner tabs have not been released.

The food!

Imagine, Roberts said, a lavish wedding.

“It’s as if,” she said, “There was a marriage between the two countries and this is the wedding reception.”

The most obvious manifestation of that is on the plate.

White House executive chef Cristeta Comerford said this menu took her “a couple of months” to design and field test. Over three courses, guests will take a tour through her Japan-influenced creations, starting with a nod to the beloved American twist on sushi, the California roll. Her version is rendered as a salad of house-cured salmon with avocado, grapefruit, watermelon radish, cucumber and shiso leaf fritters.

Beef has been a fixture of past Biden dinners – the exception, of course, being the menu for the 2023 state dinner for Indian leader Narendra Modi, a strict vegetarian. Guests at this dinner, accordingly, will move on to a dry-aged rib eye steak with blistered shishito pepper butter, a fricassee of fava beans, morels and cipollini mushrooms and a sesame oil sabayon.

And for dessert: a salted caramel pistachio cake with matcha tea ganache, cherry ice cream and a drizzle of raspberry coulis.

“We wanted to bring a little bit of the cherry blossoms that are here on the Tidal Basin right here to our dessert, in order for everyone to enjoy the cherry blossoms that we enjoy every year,” said White House executive pastry chef Susie Morrison.

The wines, as is now custom, will be American.

“The days when only French wines were served at state dinners are long gone,” Roberts said. “Primarily because there were a lot of American vineyards who basically said, ‘Whoa, what about us? We’re cool.'”

The fripperies!

A temporary water feature in the White House’s Cross Hall will feature live koi — “symbols of friendship, peace, luck and perseverance,” Biden said.

Paul Simon will perform for guests. And the first couples are exchanging gifts that include a three-legged black walnut table made by a Japanese-American-owned company, a set of records autographed by American singer Billy Joel, and, as a personal touch, “a framed painting of the Yoshino cherry tree that she planted with Mrs. Kishida on the South Lawn last spring.”

The fashion!

Japan’s first lady, Yuko Kishida, garnered rave reviews for her choice to don India’s most culturally and technically fraught of garments, the sari, by draping and meticulously pleating five meters of green Kanjeevaram silk around her body for a summit of global leaders last year in New Delhi.

As she landed in Washington for her first state visit on Tuesday — but her second trip to meet the Bidens — she greeted the couple in a flowing dress of autumn-toned watercolor florals. President Joe Biden and Prime Minister Fumio Kishida wore suits, while the U.S. first lady donned a black dress with a deep keyhole neckline and razor-sharp tailoring.

These decisions, Roberts said, are “more than just going off to the store and going, ‘Oh, that’s pretty. I think I’ll wear that.'”

And the pressure, she said, falls disproportionately on the leaders’ spouses, who are traditionally women.

“They’re ambassadors for the clothing that they wear, the look that they have,” she said. “And so all of those, all of those elements play into all of these choices. You know, the guys have it easy – just throw on the tuxedo.”

… And finally, the faux pas!

What could possibly go wrong?

Surprisingly, not a lot, Roberts said, adding, “The truth of the matter is that these state dinners tend to go off without a hitch, because the planning is done so well.”

But, she said, mistakes sometimes happen.

She described a long-ago dinner for Mexico’s leader that featured “an elaborate desert that had a guy with a sombrero sleeping as a decorative piece.”

“It was meant to be charming and kind of fun, and it just hit wrong,” she said.

Another memorable slip, she said, was at a 2009 state dinner for India, where two uninvited reality stars crashed the event.

“The fact that two people were able to get in who were not supposed to be there was, in fact, a scandal,” she said.

The East Wing, in its preview, chose to focus instead on the positive, with White House social secretary Carlos Elizondo homing in on the theme while raising the stakes of this impossibly complex event.

“That’s what we hope to capture,” he said. “…the magic of spring in our lasting friendship, each detail chosen to create a once-in-a-lifetime experience.”

Washington — The Pentagon is not backing off on its support for Israel, despite growing frustration by some U.S. lawmakers that Israel is crossing ethical lines as it goes after Hamas in Gaza.

During a U.S. Senate Armed Services Committee hearing Tuesday interrupted multiple times by protesters accusing Israel — and the United States — of having innocent blood on its hands, Defense Secretary Lloyd Austin pushed back.

Senator Tom Cotton, a Republican, asked Austin: “Is Israel committing genocide in Gaza?”

Austin replied: “Senator Cotton, we don’t have any evidence of genocide.”

But under repeated questioning, Austin acknowledged Israel’s military can and must do more to differentiate between Hamas militants and civilians.

“There’s no question that there have been far too many civilian casualties in this conflict,” he said.

Austin said he has warned his Israeli counterpart that a failure to allow the delivery of much more humanitarian aid to Gaza “would just create more terrorism.”

As for continued talk by Israel about an operation to root out Hamas in Rafah, the secretary of defense was blunt. “It cannot be what we’ve seen in the past in terms of the type of activities that we’ve seen in Gaza City and in Khan Yunis,” he said.

Not all lawmakers were satisfied with those answers. Some expressed frustration that Washington has been forced to step in.

“There’s no reason the United States should have to build a pier in the eastern Mediterranean. There’s no reason we should have to airdrop supplies,” said Senator Tim Kaine, a Democrat. “The pace of humanitarian aid is insufficient.”

Other lawmakers put blame on Hamas. Austin agreed that the U.S.-designated terror group’s ongoing conduct continues to amount to war crimes.

The hearing was about President Joe Biden’s budget request for the Department of Defense.

SEOUL, South Korea — The U.S. ambassador to the United Nations will travel to the heavily armed Korean border and meet North Korean defectors in South Korea, her office said on Monday, amid faltering U.N. efforts to ensure sanctions enforcement against the North.

Ambassador Linda Thomas-Greenfield’s trip, set for April 14-20, came after Russia rejected the annual renewal of the multinational panel of experts, which has over the past 15 years worked on the implementation of U.N. sanctions aimed at curbing North Korea’s nuclear and missile programs.

Washington, Seoul and Tokyo criticized Moscow’s veto and China’s abstention, which experts said would undermine the sanctions enforcement, with a South Korean envoy likening it to “destroying a CCTV to avoid being caught red-handed.”

Thomas-Greenfield’s trip, which will also include a stop in Japan, was meant to advance bilateral and trilateral cooperation on the sanctions and beyond, U.S. mission to the U.N. spokesperson Nate Evans said.

Both South Korea and Japan are currently members of the Security Council.

“In both countries, Ambassador Thomas-Greenfield will discuss next steps to ensure a continuation of independent and accurate reporting of the DPRK’s ongoing weapons proliferation and sanctions evasion activities,” Evans said in a statement, referring to North Korea by its official name, the Democratic People’s Republic of Korea.

In South Korea, Thomas-Greenfield will travel to the heavily fortified Demilitarized Zone between the two Koreas, meet young North Korean defectors as well as students at Ewha Womans University, Evans said.

In Japan, she will also meet family members of Japanese citizens who were abducted in the early 2000s by North Korea, and visit Nagasaki, which was hit by U.S. nuclear bombing in 1945.

washington — British researchers say Chinese nationalist trolls have been posing as American supporters of former President Donald Trump on X to try to exploit domestic divisions ahead of the U.S. election.

A report released April 1 by the Institute for Strategic Dialogue, a London think tank, says it found four previous Mandarin-tweeting accounts that went silent before re-emerging as American Trump supporter personas tweeting in English.

It linked them to China’s so-called Spamouflage network, which it described as a “long-running and widespread but largely ineffective” campaign to promote pro-Chinese Communist Party narratives.

But Elise Thomas, a senior researcher at the institute and author of the report, said pretending to be Trump supporters is a fresh and more effective tactic.

“They are posing convincingly as Americans, specifically Trump supporters,” she told VOA. “They are getting engagement from what look like real American users. That’s significantly different from what we’ve seen with Spamouflage in the past.”

She pointed out that a traditional Spamouflage tweet might have many likes and retweets, but upon further examination, it’s all from other Spamouflage accounts. Now, they are interacting with predominantly genuine American users.

“What they are doing that is quite different from other Spamouflage accounts is that they are building up authentic audiences using this thing called patriot follow trains, which is basically where people agree to mutually follow one another in order to each build their own follower accounts,” Thomas explained.

Using real viral videos and photos, these accounts seek to amplify divisive issues such as LGBTQ rights, immigration, race, gun control and crime rates.

Some of the accounts mock Biden’s age; others falsely claim that Biden is a pedophile. All seem to be promoting Trump’s slogan “Make America Great Again (MAGA),” leading the report to dub this new tactic “MAGAflage.”

One of the X accounts, Ben MAGA 2024, was opened in 2010, but previous posts have been deleted. Since April 18, 2023, the account began to tweet in English with a main theme: Biden is a pedophile and cannot be trusted.

The account tries to build a persona as an American living in Los Angeles. It posted a picture in January with the caption “Good morning! Patriots, I’m 43 years old, and passionately and loyally supporting President Trump!”

In fact, the picture belongs to a travel blog by a Danish man with no indication that he’s a Trump supporter.

 

This account also retweeted a video from Russian state media Russia Today on February 18, claiming that Biden and the Central Intelligence Agency had sent a neo-Nazi leader to fight in Ukraine.

That post was retweeted by Alex Jones, an American far-right conspiracy theorist and radio show host with 2.2 million followers on X. The post had been viewed nearly 360,000 times as of March 4.

Thomas said by wrapping a topic in a U.S. partisan political frame, they got “a reasonable amount of engagement” from real American users.

This mimics Russia’s playbook during the 2016 U.S. presidential election, when U.S. officials say Moscow used information warfare to damage the Clinton campaign, boost Trump’s chances and sow distrust in American democracy, which the Kremlin denies.

The report said some Spamouflage accounts could also be posing as left-wing Biden supporters, though they did not find any.

Twitter has since suspended all the accounts mentioned in the institute’s report.

While just a handful of accounts were identified, the report says there are almost certainly many more, which Thomas worries could have an unseen effect on the U.S. election.

“These [MAGAflage] accounts were very difficult to find. It took quite a lot of time, and I’ve only been able to find a relatively small number of them,” she said. “But because what we know from Spamouflage’s history is that everything it does, it does at massive scale. It would be really out of character for them to be only doing this, if it’s effective, at a small scale. So, that’s my concern, that it may be happening at a significantly larger scale.”

VOA reached out to the Trump and Biden campaigns for comment but did not receive a response as of publication time.

The Spamouflage network was discovered in 2019 by social media analytics firm Graphika and was first used to target Hong Kong pro-democracy protesters.

Researchers said the network is tied to “individuals associated with Chinese law enforcement,” and has been active across thousands of accounts and more than 50 platforms and forums, including Facebook, Instagram, TikTok, YouTube and X.

 

On March 11, the Office of the Director of National Intelligence issued its annual assessment on the major threats to U.S. interests around the world and warned that China’s government may “attempt to influence the U.S. elections in 2024 at some level because of its desire to sideline critics of China and magnify U.S. societal divisions.”

Liu Pengyu, a spokesperson for the Chinese Embassy in Washington, said in a statement sent to VOA that China is “committed to the principle of noninterference” and that claims about Beijing influencing U.S. presidential elections are “completely fabricated.”

Meta in August shut down close to 9,000 Facebook and Instagram accounts, groups and pages associated with the Spamouflage network.

Washington — U.S. President Joe Biden, the Democratic Party’s 2024 presidential nominee, and former President Donald Trump, the Republican Party’s presumptive nominee, hold very different views on key foreign and domestic issues. Here’s an overview of where each one stands on foreign policy.  

Russia-Ukraine  

Biden endorses sending military and humanitarian assistance to Ukraine to aid its fight against Russia, while warning that Western countries cannot allow Russian President Vladimir Putin to achieve victory. To date, the Biden administration has sanctioned Russian individuals and entities and sent $75 billion in assistance to Ukraine since the February 2022 Russian invasion. 

Biden said on March 7, 2024, “Putin of Russia is on the march, invading Ukraine and sowing chaos throughout Europe and beyond. If anybody in this room thinks Putin will stop at Ukraine, I assure you, he will not. But Ukraine can stop Putin if we stand with Ukraine and provide the weapons it needs to defend itself. That is all Ukraine is asking. They are not asking for American soldiers.”  

Trump has said NATO countries are not paying their share of aid to Ukraine and claimed the United States has sent more than other countries. At a February rally, Trump said he told an unnamed NATO member that he would encourage Russia “to do whatever the hell they want” to any alliance member that does not meet spending guidelines on defense. In a 2023 speech in New Hampshire, Trump said, “Shortly after I win the presidency, I will have the horrible war between Russia and Ukraine settled.”  

Throughout his presidency, Trump faced multiple accusations of collusion with Russia and was impeached by the U.S. House of Representatives on Dec. 18, 2019, for charges he leveraged U.S. aid to Ukraine in return for damaging information on potential political rival Joe Biden. Trump denied those charges and was later acquitted by the U.S. Senate.  

China 

Biden said on March 7, 2024, “We have the best economy in the world. And since I’ve come to office, our GDP is up, our trade deficit with China is down to the lowest point over a decade and we’re standing up against China’s unfair economic practices. We’re standing up for peace and stability across the Taiwan Strait. I’ve revitalized our partnership and alliance in the Pacific. India, Australia, Japan, South Korea, Pacific Islands. I made sure that the most advanced American technologies can’t be used in China, not allowing to trade them there. Frankly, for all this tough talk on China, it never occurred to my predecessor to do any of that. I want competition with China, not conflict. And we’re in a stronger position to win the conflict of the 21st century against China than anyone else, for that matter, than any time as well.” 

During his presidency, Trump denounced the threat posed by the Chinese Communist Party as the most significant foreign policy challenge of this generation. He said China was responsible for the COVID-19 pandemic and penalized China for ending the “one country, two states” policy in Hong Kong. In a May 2020 speech, Trump said, “The United States wants an open and constructive relationship with China, but achieving that relationship requires us to vigorously defend our national interests.”  

On his campaign website, Trump said, “To protect our country, we need to enact aggressive new restrictions on Chinese ownership of any vital infrastructure in the United States, including energy, technology, telecommunications, farmland, natural resources, medical supplies, and other strategic national assets. We should stop all future Chinese purchases in these essential industries. And we should begin the process of forcing the Chinese to sell any current holdings that put our national security at risk.”  

Israel-Palestinians  

Biden says Israel has a right to go after Hamas but has warned Israel against killing Palestinian civilians. In March, Biden announced the construction of an offshore port to deliver aid to Gaza.  

Biden said in New York on March 9, 2024, “I’m never going to leave Israel. The defense of Israel is still critical, so there’s no red line I’m going to cut off all weapons, so they don’t have the Iron Dome to protect them. They don’t have … but there’s red lines that if he crosses and they continue … you cannot have 30,000 more Palestinians dead as a consequence of going after, there’s other ways to deal, to get to, to deal with the trauma caused by Hamas.”  

Trump released a Middle East peace plan in 2020 calling for a two-state solution that would have given Israel control of a unified Jerusalem and maintained its settlements in the West Bank.  

In an interview with the Israel Hayom newspaper on March 25, 2024, Trump said of the current conflict, “What I saw October 7 was one of the saddest things I’ve ever seen. … You have to finish up your war. To finish it up. You got to get it done. And I am sure you will do that. And we got to get to peace; we can’t have this going on. And I will say, Israel has to be very careful, because you’re losing a lot of the world, you’re losing a lot of support, you have to finish up, you have to get the job done. And you have to get on to peace, to get on to a normal life for Israel.”  

Iran 

Biden spent more than two years attempting to restore the Joint Comprehensive Plan of Action, or JCPOA, the nuclear agreement negotiated by the Obama administration before declaring it “dead.” Last year, the Biden administration negotiated the release of five American hostages in return for unfreezing billions in Iranian assets.  

Biden said in Washington on March 7, 2024, “Creating stability in the Middle East also means containing the threat posed by Iran. That’s why I built a coalition of more than a dozen countries to defend international shipping and freedom of navigation in the Red Sea. I’ve ordered strikes to degrade the Houthi capability and defend U.S. forces in the region. As commander in chief, I will not hesitate to direct further measures to protect our people and our military personnel.” 

Among Trump’s proudest achievements was the withdrawal of the United States from the JCPOA. He also authorized the strike that killed Qasem Soleimani, the commander of the Quds Force — the terrorist branch of the Iranian Islamic Revolutionary Guard Corps, or IRGC — a move he called “the boldest action of his presidency.” 

North Korea 

The Biden administration has repeatedly stated it is open to negotiations with North Korea with no preconditions but has yet to offer any incentives in the form of economic assistance to encourage North Korean leader Kim Jong-Un to open talks. Biden has met with regional allies and last year announced a new nuclear deterrence agreement, with South Korea, that would allow the U.S. to dock submarines in South Korean ports.  

During his presidency, Trump pursued “complete, verifiable, and irreversible denuclearization” of North Korea but eventually developed a good personal relationship with Jong-Un after multiple meetings. His personal diplomacy did not result in any agreements between the two countries.
