FLAGSTAFF, ARIZONA — Scientists have long suspected that Mexican long-nosed bats migrate through southeastern Arizona, but without capturing and measuring the night-flying creatures, proof has been elusive. 

Researchers say they now have a way to tell the endangered species apart from other bats by analyzing saliva the nocturnal mammals leave behind when sipping nectar from plants and residential hummingbird feeders. 

Bat Conservation International, a nonprofit group working to end the extinction of bat species worldwide, teamed up with residents from southeastern Arizona, southwestern New Mexico and west Texas for the saliva-swabbing campaign. 

The samples of saliva left along potential migration routes were sent to a lab at Northern Arizona University in Flagstaff, where researchers looked for environmental DNA — or eDNA — to confirm that the bats cycle through Arizona and consider the region their part-time home. 

The Mexican long-nosed bat has been listed as endangered under the Endangered Species Act since 1988, and is the only one in Arizona with that federal protection. It is an important species for pollinating cactus, agave and other desert plants. 

Officials from the U.S. Fish and Wildlife Service and the Arizona Game and Fish Department announced the discovery in late January. While expanding Arizona’s list of bat species to 29 is exciting, wildlife managers say the use of this novel, noninvasive method to nail it down also deserves to be celebrated. 

“If we were trying to identify the species in the absence of eDNA, biologists could spend hours and hours trying to catch one of these bats, and even then, you’re not guaranteed to be successful,” said Angie McIntire, a bat specialist for the Arizona’s Game and Fish Department. “By sampling the environment, eDNA gives us an additional tool for our toolkit.” 

Every spring, Mexican long-nosed bats traverse a lengthy migratory path north from Mexico into the southwestern U.S., following the sweet nectar of their favorite blooming plants like breadcrumbs. They return along the same route in the fall. 

The bat conservation group recruited ordinary citizens for the mission, giving them kits to swab samples from bird feeders throughout the summer and fall. 

Inside the university lab, microbiology major Anna Riley extracted the DNA from hundreds of samples and ran them through machines that ultimately could detect the presence of bats. Part of the work involved a steady hand, with Riley using a syringe of sorts to transfer diluted DNA into tiny vials before popping them into a centrifuge. 

Sample after sample, vial after vial, the meticulous work took months. 

“There’s a big database that has DNA sequences of not every animal but most species, and so we could compare our DNA sequences we got from these samples to what’s in the database,” Riley said. “A little bit like a Google search — you’ve got your question, you’re asking Google, you plug it into the database, and it turns up you’ve got a bat, and you have this kind of bat.” 

Kristen Lear, of the conservation group, said the collection of eDNA has been used successfully for determining the presence of other kinds of wildlife in various environments, so the group proposed trying it with bats. 

“They do apparently leave behind a lot of spit on these plants and hummingbird feeders,” Lear said.

Fifteen measles cases — mostly in school-aged children — have been confirmed in a small county in West Texas with one of the highest rates of vaccine exemptions in the state.

South Plains Public Health District Director Zach Holbrooks said Monday that his department was first notified in late January about the first two cases in Gaines County, which he said were “two children who had seen a physician in Lubbock.”

Some of the cases appear to be connected to private religious schools in the district, said Holbrooks, who cautioned that the investigation is ongoing.

“I wouldn’t say they’re all connected, but our teams are looking into exposure sites and the background of those cases,” he said.

Local health officials set up a drive-through vaccination clinic last week and are offering screening services to residents.

The U.S. saw a rise in measles cases in 2024, including an outbreak in Chicago that sickened more than 60. This month, health officials in metro Atlanta are working to contain a measles case that spread to two unvaccinated family members.

Texas law allows children to get an exemption from school vaccines for reasons of conscience, including religious beliefs.

The percentage of kids with exemptions has risen over the last decade from .76% in 2014 to 2.32% last year, according to Texas Department of State Health Services data.

Gaines County has one of the highest rates in Texas of school-aged children who opt out of at least one required vaccine: Nearly 14% of children from kindergarten through grade 12 had an exemption in the 2023-24 school year, which is more than five times the state average of 2.32% and beyond the national rate of 3.3%.

But the number of unvaccinated kids in the county is likely significantly higher, DSHS spokesperson Lara Anton said, because Gaines County has many children who are homeschooled and whose data would not be reported.

The measles, mumps and rubella vaccines are a two-shot series: The first is recommended at 12 to 15 months old and second between 4 to 6 years old. The vaccine is required to attend most public schools in the U.S.

But vaccination rates have declined nationwide since the COVID-19 pandemic and most states are below the 95% vaccination threshold for kindergartners — the level needed to protect communities against measles outbreaks. Lawmakers across the country have proposed various vaccine requirement changes at a time when anti-vaccine activist Robert F. Kennedy Jr. is awaiting confirmation as the secretary of Health and Human Services.

One of the early Gaines County cases traveled to neighboring New Mexico while they were still infectious, Anton said, but there were no immediate reports of infection. New Mexico Department of Health spokesperson Robert Nott said the agency has been in communication with Texas officials but there was no known exposure to measles in his state.

“We’re going to watch this very closely,” Nott said.

Two cases of measles were reported in early January in the Houston area, but Holbrooks said the West Texas cases don’t appear to be connected.

Measles is a highly contagious virus that can survive in the air for up to two hours. Up to 9 out of 10 people who are susceptible will get the virus if exposed, according to the U.S. Centers for Disease Control and Prevention. Before the vaccine was introduced in 1963, the U.S. saw some 3 million to 4 million cases per year. Now, it’s usually fewer than 200 in a normal year.

CAPE CANAVERAL, FLORIDA — Europe’s Euclid space telescope has detected a rare halo of bright light around a nearby galaxy, astronomers reported Monday. The halo, known as an Einstein ring, encircles a galaxy 590 million light-years away, considered close by cosmic standards.  

A light-year is 5.8 trillion miles. Astronomers have known about this galaxy for more than a century and so were surprised when Euclid revealed the bright glowing ring, reported in the journal Astronomy and Astrophysics.  

An Einstein ring is light from a much more distant galaxy that bends in such a way as to perfectly encircle a closer object, in this case a well-known galaxy in the constellation Draco.  

The faraway galaxy creating the ring is more than 4 billion light-years away. Gravity distorted the light from this more distant galaxy, thus the name honoring Albert Einstein. The process is known as gravitational lensing.

“All strong lenses are special, because they’re so rare, and they’re incredibly useful scientifically. This one is particularly special, because it’s so close to Earth and the alignment makes it very beautiful,” lead author Conor O’Riordan of Germany’s Max Planck Institute for Astrophysics said in a statement.

Euclid rocketed from Florida in 2023. NASA is taking part in its mission to detect dark energy and dark matter in the universe.

PARIS — Nearly all nations missed a UN deadline Monday to submit new targets for slashing carbon emissions, including major economies under pressure to show leadership following the U.S. retreat on climate change.

Just 10 of nearly 200 countries required under the Paris Agreement to deliver fresh climate plans by Feb. 10 did so on time, according to a UN database tracking the submissions.

Under the climate accord, each country is supposed to provide a steeper headline figure for cutting heat-trapping emissions by 2035, and a detailed blueprint for how to achieve this.

Global emissions have been rising but need to almost halve by the end of the decade to limit global warming to levels agreed under the Paris deal.

UN climate chief Simon Stiell has called this latest round of national pledges “the most important policy documents of this century.”

Yet just a handful of major polluters handed in upgraded targets on time, with China, India and the European Union the biggest names on a lengthy absentee list.

Most G20 economies were missing in action with the United States, Britain and Brazil — which is hosting this year’s UN climate summit — the only exceptions.

The US pledge is largely symbolic, made before President Donald Trump ordered Washington out of the Paris deal.

Accountability measure

There is no penalty for submitting late targets, formally titled nationally determined contributions (NDCs).

They are not legally binding but act as an accountability measure to ensure governments are taking the threat of climate change seriously.

Last week, Stiell said submissions would be needed by September so they could be properly assessed before the UN COP30 climate conference in November.

A spokeswoman for the EU said the 27-nation bloc intended to submit its revised targets “well ahead” of the summit in Belem.

Analysts say China, the world’s biggest polluter and also its largest investor in renewable energy, is also expected to unveil its much-anticipated climate plan in the second half of the year.

The United Arab Emirates, Ecuador, Saint Lucia, New Zealand, Andorra, Switzerland and Uruguay rounded out the list of countries that made Monday’s cut-off.

The sluggish response will not ease fears of a possible backslide on climate action as leaders juggle Trump’s return and other competing priorities from budget and security crises to electoral pressure.

Ebony Holland from the London-based International Institute for Environment and Development said the US retreat was “clearly a setback” but there were many reasons for the tepid turnout.

“It’s clear there are some broad geopolitical shifts underway that are proving to be a challenge when it comes to international cooperation, especially on big issues like climate change,” she said.

JAKARTA, INDONESIA — Economists are raising concerns about the viability of Indonesian President Prabowo Subianto’s program launched this year to combat child nutrition.

According to an Indonesian Ministry of Health Nutritional Status Study report, 21.6% of children ages 3 and 4 experienced stunting caused by malnutrition in 2022.

The first stage of the Free Nutritious Meal Program, extending through March, is intended to provide around 20 million Indonesian school children, pregnant women and breastfeeding mothers meals to improve their health and prevent stunting.

The effort was initially projected to cost $28 billion over five years. However, Coordinating Minister for Food Zulkifli Hasan said on Jan. 9 during a meeting on food security that the $4.4 billion budgeted for this year will run out in June and that $8.5 billion more will be requested to fund the program through December.

China, Japan, the United States and India have expressed support for the program, although it is unclear how much money will be provided or what form that support will take. Japan and India have said their help will be in the form of training.

Officials plan to implement the program in stages, eventually reaching 83 million people — more than a quarter of Indonesia’s 280 million population — by 2029, Muhammad Qodari, deputy chief of the presidential staff told reporters on Feb. 3.

The program is part of a long-term strategy to develop the nation’s youth to achieve a “Golden Indonesia” generation, referring to a plan to make Indonesia a sovereign, advanced and prosperous nation by its 2045 centennial.

The program’s cost could make Prabowo politically vulnerable, according to Dinna Prapto Raharja, a professor of international relations at Jakarta’s Bina Nusantara University and a senior policy adviser at Jakarta consulting firm Synergy Policies.

“In order to finance this program, Prabowo has taken steps to implement major cutbacks in his government budget with some ministries seeing 50% cuts,” Dinna said.

“Now he is forced to seek financial assistance from overseas sources.” she told VOA on Jan. 31.

The Finance Ministry said the spending cuts would amount to $18.7 billion, 8% of this fiscal year’s approved spending.

While other nations said they would support the program, officials from the National Nutrition Agency — which manages the program — said internal talks about the level of foreign aid, type of assistance and technical aspects of its implementation have not begun.

Support from China, Japan, US and India

In November, China committed to supporting free nutritious meals but did not pledge a specific amount.

The Chinese Embassy in Jakarta did not respond to VOA requests for further information on the value and form of the assistance. It remains unclear whether China’s financial assistance will be in the form of a loan or grant.

The United States is providing training to Indonesian dairy farmers to support the program, which has increased the demand for locally produced milk. Indonesia, so far, can provide milk only two to three times a week to school children, according to Deddy Fachrudin Kurniawan, CEO of Dairy Pro Indonesia and project leader of U.S. Dairy Export Council training.

Deddy told VOA on Jan. 8 that Indonesia has had to import 84% of its milk in the past, and that demand will double because of the food program.

In January, Japanese Prime Minister Shigeru Ishiba announced Japan will support the meal program by helping the Indonesian government increase its ability to combat childhood malnutrition.

Ishiba offered Japan’s support by training Indonesian cooks and sending Japanese chefs to assist. Prabowo added that Japan will also assist in improving the fishery and agriculture sectors, based on Japan’s experience.

More recently, India reaffirmed support for the program through the sharing of knowledge of the government’s Food Corporation of India and other institutions with Indonesian officials.

“India shares its experiences in the fields of health and food security, including the [free] lunch scheme and public [service] distribution system to the Indonesia government,” Prime Minister Narendra Modi said on his YouTube channel on Jan. 25.

Other support and reaction

Other countries have said they support the program. France and Brazil expressed their support on the sidelines of the recent G20 Leaders Summit in Rio de Janeiro.

Prabowo instructed his team to arrange a visit of an Indonesian delegation to Brazil to take notes from the South American country’s similar program. France, which has a similar school feeding program, intends to share its expertise and help Indonesia modernize its agricultural sector.

Teuku Rezasyah, an associate professor of international relations at Bandung’s Universitas Padjajaran, noted that India exported 20,000 metric tons of water buffalo meat to Indonesia last year while Brazil exported 100,000 metric tons of beef to Indonesia.

British Deputy Prime Minister Angela Reynar showed similar interest during her meeting with Prabowo in London in November. However, it remains unclear what type of support the U.K will offer.

Mohammad Faisal, executive director of the Center of Reform on Economics, told VOA in Jakarta on Jan. 31 that countries offering support will have their own interests in mind, as well.

“I believe there’s no free lunch,” Faisal said. “The donations may be partly altruistic, but not entirely. Donor countries consider it as strengthening bilateral ties, but they may also expect to reap the benefits in the future, such as enjoying ease of investing in Indonesia through incentives and getting better penetration of export markets as a reward.”

Rezasyah agreed.

“Donor countries are probably hoping Indonesia will import more products from their countries to support this multibillion-dollar supplemental food program,” he said. “On the other hand, they see Indonesia becoming a middle power that could contribute to finding solutions to global affairs.”

NEW YORK — All live poultry markets in New York City and some of its suburbs were ordered Friday to close for a week after the detection of seven cases of avian flu, which has also hit farms nationwide.

Governor Kathy Hochul said that there was no immediate threat to public health and that the temporary closure of bird markets in the city and its Westchester County and Long Island suburbs came out of an abundance of caution. No cases of avian flu have been detected among humans in New York, officials said. 

The birds infected with the virus were found during routine inspections of live bird markets in the New York City boroughs of the Bronx, Brooklyn and Queens. 

The U.S. Centers for Disease Control and Prevention has said the virus poses low risk to the general public. The agency said there have been 67 confirmed cases of bird flu in humans in the U.S., with illnesses mild and mostly detected among farmworkers who were exposed to sick poultry or sick dairy cows. 

The first bird flu death in the U.S. was reported last month in Louisiana, with health officials saying the person was older than 65, had underlying medical problems and had been in contact with sick and dead birds in a backyard flock. 

In New York, live bird markets where the virus was detected have to dispose of all poultry in a sanitary manner, according to the state’s order. Other bird markets that do not have cases will have to sell off remaining poultry within three days, clean and disinfect their operations, and then remain closed for at least five days and be inspected by state officials before reopening. 

Ahead of the mandatory disposal order for markets with no cases, employees at La Granja, a halal-certified poultry market in Manhattan’s Harlem neighborhood, raced to sell the remaining inventory: around 200 live chickens of different varieties, along with turkeys, quail, ducks, roosters, pigeons and rabbits. 

Any remaining animals would be slaughtered and given to employees and longtime customers, according to Jose Fernandez, the owner. 

“We’re going to lose money, for now,” he said. “But the law is the law. They know what they’re doing.” 

The H5N1 strain of bird flu has been spreading among wild birds, poultry, cows and other animals. Officials have urged people who come into contact with sick or dead birds to wear respiratory and eye protection and gloves when handling poultry. 

More than 156 million birds nationwide have been affected by the outbreak, many at large farming operations that have had to slaughter their entire flocks. 

Despite growing attention on the avian flu, New York City’s poultry markets appeared to be doing brisk business Friday. 

Outside the Wallabout Poultry market in Brooklyn, a line of customers took numbers and picked their chickens, which employees snatched from crowded cages, weighing them upside down, before taking them to a back room to be slaughtered. 

“I’m not worried about any bird flu,” said Stan Tara, 42, of Brooklyn, as he purchased a large chicken for $22.50. “It’s the same as you buy from the supermarket. A little more expensive, but at least it’s fresh.” 

Some animal rights groups, meanwhile, questioned the purpose of a state order that allowed the markets to continue selling fowl, rather than shutting them down immediately. 

“The public is going into markets where no one knows if there are outbreaks of avian flu, then taking home dead birds that may or may not be infected,” said Edita Birnkrant, executive director of NYCLASS, which has long raised alarms about conditions within the city’s roughly 70 live animal markets. “It’s ludicrous.” 

U.S. egg prices are likely to remain high past Easter and well into 2025, largely because of avian flu, according to CoBank, a Denver-based provider of loans and other financial services to the agriculture sector. 

The highly contagious virus has affected nearly 100 million egg-laying hens in the U.S. since 2022. 

But CoBank said other factors are also causing supply constraints and driving up prices, such as skyrocketing consumer demand for eggs in recent years. Fast-growing breakfast and brunch chains are also eating up supplies.

NEW YORK — The U.S. winter virus season is in full force, and by one measure is the most intense in 15 years.

One indicator of flu activity is the percentage of doctor’s office visits driven by flu-like symptoms. Last week, that number was clearly higher than the peak of any winter flu season since 2009-10, according to data posted Friday by the U.S. Centers for Disease Control and Prevention.

Of course, other viral infections can be mistaken for flu. But COVID-19 appears to be on the decline, according to hospital data and CDC modeling projections. Available data also suggests another respiratory illness, RSV, or respiratory syncytial virus, has been fading nationally.

The flu has forced schools to shut down in some states. The Godley Independent School District, a 3,200-student system near Fort Worth, Texas, last week closed for three days after 650 students and 60 staff were out Tuesday.

Jeff Meador, a district spokesman, said most illnesses there have been flu, plus some strep throat. He called it the worst flu season he could remember.

So far this season, the CDC estimates, there have been at least 24 million flu illnesses, 310,000 hospitalizations and 13,000 deaths — including at least 57 children.

Traditionally, flu season peaks around February.

Overall, 43 states reported high or very high flu activity last week. Flu was most intense in the South, Southwest and Western states.

In Rochester, New York, the flu season has been intense but not necessarily worse than at the peak of other years, said Dr. Elizabeth Murray, a pediatric emergency medicine doctor at the University of Rochester Medical Center.

She said there is a lot of flu, but there is also still a lot of RSV and a surprising number of babies with COVID-19.

“All of the respiratory illnesses are around, with a vengeance,” Murray added.

The CDC declined to let an Associated Press reporter speak to an agency flu expert about recent trends. The Trump administration ordered a temporary “pause” on health agency communications and has continued to refuse interview requests that were routinely granted in the past.

U.S. health officials recommend that everyone 6 months and older get an annual flu vaccination.

About 44% of adults got flu shots this winter, the same as last winter. But coverage of children is down, at about 45% this winter. It’s usually around 50%, according to CDC data.

About 23% of U.S. adults were up to date on their COVID-19 vaccinations as of late January, up from about 20% at the same point in time the year before. COVID-19 vaccination rates for kids were about the same, at around 12%.

The government has not yet reported its estimates of how well this season’s flu vaccine is working.

Testing results from patients indicate that two strains of seasonal flu are causing the most illnesses: type A H1N1 and H3N2. Health officials are closely watching a third strain — H5N1 bird flu — that has sickened tens of millions of animals and is known to have infected 67 people in the U.S.

To avoid seasonal viruses, doctors say you should avoid touching your eyes, nose and mouth because germs can spread that way. You should also wash your hands with soap and water, clean frequently touched surfaces, and avoid close contact with people who are sick.

JOHANNESBURG, SOUTH AFRICA — Some South African organizations that assist people with HIV are in limbo, after the United States put a 90-day freeze on most foreign aid. The U.S. State Department later added a waiver for “lifesaving” aid, but NGOs that have already shut their doors say the next steps aren’t clear, and they are worried this could set back years of progress.

South Africa has the highest number of HIV-positive people in the world — about 8 million — but has also been a huge success story in terms of treatment and preventing new infections.

That’s largely due to the money poured into expert HIV care here, 17% of which comes from a U.S. program called the President’s Emergency Plan for AIDS Relief, also known as PEPFAR.

But, a 90-day foreign aid funding freeze is in effect, following an executive order by U.S. President Donald Trump last month to check if U.S.-funded programs overseas are aligned with U.S. policies. This has caused some confusion in South Africa with health care organizations and their patients.

Thamsanqa Siyo, an HIV-positive transgender woman in South Africa, is anxious.

“People are frustrated, they’re living in fear, they don’t know what’s going to happen,” said Siyo. “They don’t know if it’s stopped temporarily or not temporarily.”

The Cape Town clinic that Siyo used to go to has now been closed for two weeks.

While the State Department has issued a waiver to continue paying for “lifesaving” services, what that includes remains unclear to many South African organizations that receive funding from PEPFAR.

U.S. Secretary of State Marco Rubio said this week that the waiver was clear.

“If it saves lives, if it’s emergency lifesaving aid — food, medicine, whatever — they have a waiver,” said Rubio. “I don’t know how much clearer we can be.”

The State Department also issued written clarification and guidance on February 1 regarding which activities are and are not covered by the waiver for PEPFAR programs.

The South African government said it was blindsided by the U.S. aid freeze, according to Health Minister Aaron Motsoaledi, who convened a meeting about PEPFAR on Wednesday.

Motsoaledi also said he has sought clarity on the waiver.

“If you say American money cannot be used for LGBTQWI+ and we do the counseling and testing and somebody who falls within that category, transgender, tests positive, can they not be helped?” he asked. “Even if it’s lifesaving?”

Linda-Gail Bekker is a doctor and scientist who heads the Desmond Tutu HIV Center in South Africa.

“This is not one homogenous picture,” said Bekker. “In some places, it’s parts of services that have been stopped. In other places, the whole clinic, if it was supplied by PEPFAR, has been closed down.”

She also said that some transgender health services have been completely closed, and in other areas, counselors haven’t been able to come in.

In addition, she said some services and drugs are no longer available, such as community-based testing and pre-exposure prophylaxis, a medicine that prevents people at high risk from contracting HIV.

Ling Sheperd, who works for Triangle Project, an nongovernmental organization that provides services for the queer community, said there’s a risk of “undoing decades of progress.”

“The impact is devastating,” said Sheperd. “The PEPFAR funding has been a lifeline for millions and it ensures access to HIV treatment, prevention services, and of course community-based health care. And without it we are seeing interruptions in medication supply, clinics are scaling back services, and community health workers have literally been losing their livelihoods.”

About 5.5 million South Africans are on anti-retroviral medication for HIV. Motsoaledi noted that most of that is funded by the government here.

However, he said, a PEPFAR shortfall will affect training, facilities and service delivery. The government said it is working on contingency plans that would reduce dependence on foreign aid in the HIV sector.

On Wednesday, a group of health organizations sent a letter to the South African government saying at least 900,000 patients with HIV were directly affected by the U.S. stop-work orders.
