Experts from nine countries are planning to collect and combine aquatic animal sounds for a global library. Scientists in Australia believe an undersea chorus of mammals, fish and some invertebrates will help them gauge the health of marine ecosystems.

Songs by bearded seals and the “boing” of a minke whale are part of a global collection being put together for the first time by a team of international researchers.

The samples are stored in the individual libraries of various institutions, but never before have they been curated in a single collection.

All marine mammals, including the humpback whale, are thought to emit sounds, along with many fish and invertebrates. A new data bank aims to use these recordings to measure biodiversity and the health of ecosystems.

Miles Parsons, a researcher at the Australian Institute of Marine Science and the lead author of a report on the databank, says animal sounds can indicate the health of an ecosystem.

“When you are talking about things like soundscapes, there is a lot of work recently that has been done to tease out the acoustic characteristics of a soundscape to be able to identify the type of habitat that it is and even start to look at the quality of the habitat. There has been some work recently where they have looked at the difference between degraded coral reefs and healthy coral reefs and the differences in the soundscapes that you have between those. There’s lots of different applications that you can get from this, from passive acoustic monitoring.”

The mulloway is one of the loudest fish in the world. Of the 34,000 known species of fish, only 1,000 have had their sounds documented.

Researchers use highly sophisticated ocean hydrophones, or underwater microphones, to record sounds. Amateur divers have used underwater cameras to record the squeaks and groans of marine life, and they submit their findings to academics.

And some birds reportedly make underwater noises.

Scientists believe that pollution and warming temperatures are changing underwater acoustics.

The research paper “Sounding the Call for a Global Library of Biological Underwater Sounds” was published in the journal “Frontiers in Ecology and Evolution.”

It is a collaboration between experts from various countries, including Britain, China, New Zealand and the United States.

A study released Tuesday by the U.S. Centers for Disease Control and Prevention suggests that infants are less likely to be hospitalized with COVID-19 if their mothers are vaccinated during their pregnancy.

The study found that babies whose mothers received two doses of an mRNA vaccine while pregnant were about 60% less likely to be hospitalized for the virus during their first six months of life. The odds are strengthened if the mother is vaccinated after the first 20 weeks of pregnancy.  

The agency has urged all women who are pregnant, breastfeeding or planning to get pregnant to get vaccinated against the coronavirus, which it says increases the risk of a variety of complications, including premature birth and stillbirth.

The CDC researchers based their conclusions from monitoring 379 infants who had been hospitalized at 20 pediatric hospitals across the U.S. between last July and January of this year, including 176 who tested positive for COVID-19.

In another vaccine-related development, Britain’s Health Security Agency says the results of several studies suggests a COVID-19 vaccine reduces the chances of someone suffering from the lingering effects of a COVID-19 infection, a condition commonly known as “long COVID,” according to The Guardian newspaper.

The agency came to its conclusion after examining data from 15 studies conducted at home and abroad, half of which looked at whether the vaccine could protect someone from developing long COVID if they had not been infected, with the others focusing on the effect of vaccination among people who were already suffering from long COVID.

The HSA researchers found that those who have received one or two doses of a vaccine are less likely to develop long COVID symptoms, such as fatigue, headaches, hair loss, shortness of breath or loss of smell, compared with those who are unvaccinated. The review also said there was evidence that unvaccinated people suffering from long COVID had fewer or reduced symptoms once they were vaccinated, compared to those who remained unvaccinated.

Meanwhile, South Korea says its daily number of new COVID-19 cases has risen above 90,000 for the first time Wednesday. The 90,443 new infections reported by the Korea Disease Control and Prevention Agency was a dramatic increase from the 57,164 new cases from Tuesday.

Despite the increasing number of new cases driven by the highly-contagious omicron variant, Prime Minister Kim Boo-kyum said the government may soon ease current coronavirus restrictions, including lifting a 9 p.m. curfew on restaurants, cafes and bars, and ending the cap on the number of people allowed for private gatherings at six.

In the United States, the administration of President Joe Biden has told key lawmakers that it needs an additional $30 billion to fund its COVID-19 response efforts.

The extra spending requested by President Biden comes nearly a year after passage of the massive $1.9 trillion American Rescue Plan aimed at helping the U.S. economy recover from the pandemic. White House press secretary Jen Psaki said Tuesday that while the administration continues to have “sufficient funds” to respond to the current omicron-driven surge, “our goal has always been to ensure that we are well prepared to stay ahead of the virus.”

A U.S. government report warns that sea levels along America’s coasts will rise about an average of 30.5 centimeters over the next 30 years, about equal to water level increases recorded in the past 100 years.

The report released Tuesday by the National Oceanic and Atmospheric Administration and six other federal agencies predicted the Gulf Coast, especially Texas and Louisiana, will get hit hardest. The Atlantic coast will also see higher than average sea level rise, while it will be less on the Pacific coast, the report said.

Scientists say the higher sea levels are the result of climate change and will spark more coastal floods on sunny days when it isn’t storming.

The study’s lead author, William Sweet, an oceanographer for NOAA’s National Ocean Service, said the worst of the long-term effects of the sea level increases from melting ice sheets in Antarctica and Greenland probably won’t begin to be felt until after 2100.

U.S. cities such as Annapolis, Maryland; Miami Beach, Florida; and Norfolk, Virginia, already get a few minor floods a year during high tides, but the researchers said that by 2050, those will be replaced by several “moderate” yearly floods that cause property damage.

Pollution by states and companies is contributing to more deaths globally than COVID-19, a U.N. environmental report published on Tuesday said, calling for “immediate and ambitious action” to ban some toxic chemicals.

The report said pollution from pesticides, plastics and electronic waste is causing widespread human rights violations and at least 9 million premature deaths a year, and that the issue is largely being overlooked.

The coronavirus pandemic has caused close to 5.9 million deaths, according to data aggregator Worldometer.

“Current approaches to managing the risks posed by pollution and toxic substances are clearly failing, resulting in widespread violations of the right to a clean, healthy and sustainable environment,” the report’s author, U.N. Special Rapporteur David Boyd, concluded.

“I think we have an ethical and now a legal obligation to do better by these people,” he told Reuters later in an interview.

Due to be presented next month to the U.N. Human Rights Council, which has declared a clean environment a human right, the document was posted on the Council’s website on Tuesday.

It urges a ban on polyfluoroalkyl and perfluoroalkyl, man-made substances used in household products such as non-stick cookware that have been linked to cancer and dubbed “forever chemicals” because they don’t break down easily.

It also seeks the clean-up of polluted sites and, in extreme cases, the possible relocations of affected communities – many of them poor, marginalized and indigenous – from so-called “sacrifice zones”.

That term, originally used to describe nuclear test zones, was expanded in the report to include any heavily contaminated site or place rendered uninhabitable by climate change.

“What I hope to do by telling these stories of sacrifice zones is to really put a human face on these otherwise inexplicable, incomprehensible statistics (of pollution death tolls),” Boyd said.

Boyd considers the report, his latest in a series, to be his most hard-hitting yet and told Reuters he expects “push back” when he presents it to the Council in Geneva.

U.N. rights chief Michelle Bachelet has called environmental threats the biggest global rights challenge, and a growing number of climate and environmental justice cases are invoking human rights with success.

Chemical waste is set to be part of negotiations at a U.N. environment conference in Nairobi, Kenya, starting on Feb. 28, including a proposal to establish a devoted panel, similar to the Intergovernmental Panel on Climate Change.

A billionaire who led an all-private space crew into orbit last year has announced plans for up to three new missions in conjunction with SpaceX, including one with a spacewalk.

Jared Isaacman, who founded payment processing company Shift4, will lead the first of the new flights with a launch potentially coming by the end of this year. 

In addition to a mission featuring the first spacewalk attempted by non-professional astronauts, the planned flight also includes achieving a record altitude in Earth orbit.

As part of the partnership with SpaceX, the flights are set to utilize SpaceX spacecrafts.

As few as three major criminal groups are responsible for smuggling the vast majority of elephant ivory tusks out of Africa, according to a new study.

Researchers used analysis of DNA from seized elephant tusks and evidence such as phone records, license plates, financial records and shipping documents to map trafficking operations across the continent and better understand who was behind the crimes. The study was published Monday in the journal Nature Human Behavior.

“When you have the genetic analysis and other data, you can finally begin to understand the illicit supply chain — that’s absolutely key to countering these networks,” said Louise Shelley, who researches illegal trade at George Mason University and was not involved in the research.

Conservation biologist Samuel Wasser, a study co-author, hopes the findings will help law enforcement officials target the leaders of these networks instead of low-level poachers who are easily replaced by criminal organizations.

“If you can stop the trade where the ivory is being consolidated and exported out of the country, those are really the key players,” said Wasser, who co-directs the Center for Environmental Forensic Science at the University of Washington.

Africa’s elephant population is fast dwindling. From around 5 million elephants a century ago to 1.3 million in 1979, the total number of elephants in Africa is now estimated to be around 415,000.

A 1989 ban on international commercial ivory trade hasn’t stopped the decline. Each year, an estimated 1.1 million pounds (500 metric tons) of poached elephant tusks are shipped from Africa, mostly to Asia.

For the past two decades, Wasser has fixated on a few key questions: “Where is most of the ivory being poached, who is moving it, and how many people are they?”

He works with wildlife authorities in Kenya, Singapore, Hong Kong, Malaysia and elsewhere, who contact him after they intercept ivory shipments. He flies to the countries to take small samples of tusks to analyze the DNA. He has now amassed samples from the tusks of more than 4,300 elephants trafficked out of Africa between 1995 and today.

“That’s an amazing, remarkable data set,” said Princeton University biologist Robert Pringle, who was not involved in the study. With such data, “it becomes possible to spot connections and make strong inferences,” he said.

In 2004, Wasser demonstrated that DNA from elephant tusks and dung could be used to pinpoint their home location to within a few hundred miles. In 2018, he recognized that finding identical DNA in tusks from two different ivory seizures meant they were harvested from the same animal – and likely trafficked by the same poaching network.

The new research expands that approach to identify DNA belonging to elephant parents and offspring, as well as siblings — and led to the discovery that only a very few criminal groups are behind most of the ivory trafficking in Africa.

Because female elephants remain in the same family group their whole life, and most males don’t travel too far from their family herd, the researchers hypothesize that tusks from close family members are likely to have been poached at the same time, or by the same operators.

Such genetic links can provide a blueprint for wildlife authorities seeking other evidence — cell phone records, license plates, shipping documents and financial statements — to link different ivory shipments.

Previously when an ivory shipment was intercepted, the one seizure wouldn’t allow authorities to identify the organization behind the crime, said Special Agent John Brown III of the Office of Homeland Security Investigations, who has worked on environmental crimes for 25 years.

But the scientists’ work identifying DNA links can “alert us to the connections between individual seizures,” said Brown, who is also a co-author. “This collaborative effort has definitely been the backbone of multiple multinational investigations that are still ongoing,” he said.

They identified several poaching hotspots, including regions of Tanzania, Kenya, Botswana, Gabon and Republic of Congo. Tusks are often moved to warehouses in another location to be combined with other contraband in shipping containers, then moved to ports. Current trafficking hubs exist in Kampala, Uganda; Mombasa, Kenya; and Lome, Togo.

Two suspects were recently arrested as a result of one such investigation, said Wasser.

Traffickers that smuggle ivory also often move other contraband, the researchers found. A quarter of large seizures of pangolin scales – a heavily-poached anteater-like animal – are co-mingled with ivory, for instance.

“Confronting these networks is a great example of how genetics can be used for conservation purposes,” said Brian Arnold, a Princeton University evolutionary biologist who was not involved in the research.

The Intergovernmental Panel on Climate Change, or IPCC, has begun a two-week meeting to consider a report that assesses the impact of the world’s changing climate and how humans might adapt.

Hundreds of scientists meeting virtually will lay out the latest evidence on how past and future changes to the Earth’s climate system are affecting the planet.

The report under review is the second of three installments that will comprise the IPCC’s Sixth Assessment Report, which will be released later this year.

In August, the scientific body approved the first contribution of Working Group I, which dealt with the physical science basis of climate change.

The second part, currently under review, highlights the role of social justice and diverse forms of knowledge, such as indigenous and local knowledge, might play to strengthen climate change action and reduce the risks.

The chair of the IPCC, Hoesung Lee, said the report focuses on solutions and productive areas for action.

“It will be more strongly integrated, the natural, social and economic sciences. And it will provide policymakers with sound data and knowledge to help them shape policies and make decisions. The need for the Working Group II report has never been greater because the stakes have never been higher,” he said.

The United Nations-backed IPCC was established in 1988 to provide political leaders with periodic scientific assessments regarding climate change. The panel previously issued five assessment reports that spotlighted climate change as an issue of growing global importance.

The Paris Agreement on climate change calls for limiting human-induced global warming to well below 2 degrees Celsius, preferably 1.5 degrees Celsius, above pre-industrial levels. The IPCC warns that mark will be exceeded this century, unless drastic action is taken.

Secretary-General of the World Meteorological Organization, Petteri Taalas, said weather-related disasters have been increasing dramatically over the past two decades.

He said vulnerable areas in tropical latitudes, especially in Africa, Southern Asia and the Pacific are suffering the worst impacts of climate-driven disasters.

He said he often uses a sports analogy to communicate the seriousness of climate change to humanity.

“We have at the moment Winter Olympics going on in China. We have high-performing athletes. And if you give them doping, then they perform even more expertly. So, that is what we have done with the atmosphere. We have been doping the atmosphere,” said Taalas.

The contribution by Working Group III, dealing with the mitigation of climate change, will be finalized in April. The concluding synthesis of IPCC’s Sixth Assessment Report will be made in September.
