MEXICO CITY — The number of monarch butterflies wintering in the mountains west of Mexico City rebounded this year, doubling the area they covered in 2024 despite the stresses of climate change and habitat loss, experts said Thursday.

The annual butterfly count doesn’t calculate the individual number of butterflies, but rather the number of acres they cover as they gather on tree branches in the mountain pine and fir forests.

Monarchs from east of the Rocky Mountains in the United States and Canada overwinter there. Mexico’s Commission for National Protected Areas (CONANP) said that this year, butterflies covered 1.79 hectares) compared to only 0.9 hectares the year before.

Last year’s figure represented a 59% drop from 2023, the second lowest level since record keeping began.

After wintering in Mexico, the iconic butterflies with black and orange wings fly north, breeding multiple generations along the way for thousands of miles. The offspring that reach southern Canada begin the trip back to Mexico at the end of summer.

Gloria Tavera Alonso, the Mexican agency’s director general of conservation, said the improved numbers owed to better climatic factors and humidity.

Drought along the butterflies’ migratory route had been listed as a factor in last year’s decline. The impact of changes in weather year after year mean fluctuations are expected.

For that, Jorge Rickards, Mexico director general for the World Wildlife Fund, said “you can’t let down your guard” and must continue to expand conservation efforts.

Tavera Alonso credited ongoing efforts to increase the number of plants the butterflies rely on for sustenance and reproduction along their flyway.

Butterflies have not been faring well north of the border. The Xerces Society for Invertebrate Conservation has been counting western overwinter populations of monarch butterflies — a separate population from those that winter in central Mexico — along the California coast, northern Baja California and inland sites in California and Arizona for the last 28 years. The highest number recorded was 1.2 million in 1997.

The organization announced in February that it counted just 9,119 monarchs in 2024, a decrease of 96% from 233,394 in 2023. The total was the second-lowest since the survey began in 1997. And the first countrywide systematic analysis of butterfly abundance in the United States found that the number of butterflies in the Lower 48 states has been falling on average 1.3% a year since the turn of the century, with 114 species showing significant declines and only nine increasing, according to a study in Thursday’s journal Science.

Experts say that monarchs face risks across North America in large part due to the reduction in milkweed where the monarchs lay their eggs. The plant has been disappearing due to drought, wildfires, herbicides and urbanization.

In December, the U.S. Fish and Wildlife Service proposed that monarch butterflies receive protection as a threatened species under the Endangered Species Act.

WASHINGTON — Giving a new meaning to the phrase mad scientists, angry researchers, doctors, their patients and supporters ventured out of labs, hospitals and offices Friday to fight against what they call a blitz on life-saving science by the Trump administration.

In the nation’s capital, a couple thousand gathered at the Stand Up for Science rally. Organizers said similar rallies were planned in more than 30 U.S. cities.

Politicians, scientists, musicians, doctors and their patients made the case that firings, budget and grant cuts in health, climate, science and other research government agencies in the Trump administration’s first 47 days in office are endangering not just the future but the present.

“This is the most challenging moment I can recall,” University of Pennsylvania climate scientist Michael Mann told the crowd full of signs belittling the intelligence of President Donald Trump, his cost-cutting aide Elon Musk and Health and Human Services Secretary Robert F. Kennedy Jr. “Science is under siege.”

Astronomer Phil Plait told a booing crowd, “We’re looking at the most aggressively anti-science government the United States has ever had.”

Rally co-organizer Colette Delawalla, a doctoral student in clinical psychology, said, “We’re not just going to stand here and take it.”

Science communicator, entertainer and one-time engineer Bill Nye the Science Guy challenged the forces in government that want to cut and censor science. “What are you afraid of?” he said.

U.S. Senator Chris Van Hollen challenged the crowd, some in white lab coats if only for show, to live up to the mad scientist moniker: “Everybody in America should be mad about what we are witnessing.”

The crowd was. Signs read “Edit Elon out of USA’s DNA,” “Delete DOGE not data,” “the only good evidence against evolution is the existence of Trump” and “ticked off epidemiologist.”

Health and science advances are happening faster than ever, making this a key moment in making people’s lives better, said former National Institutes of Health Director Francis Collins, who helped map the human genome. The funding cuts put at risk progress on Alzheimer’s disease, diabetes and cancer, he said.

“It’s a very bad time with all the promise and momentum,” said Collins.

“I’m very worried about my country right now,” Collins said before breaking out into an original song on his guitar.

Emily Whitehead, the first patient to get a certain new type of treatment for a rare cancer, told the crowd that at age 5 she was sent hospice to die, but CAR T-cell therapy “taught my immune system to beat cancer” and she’s been disease free for nearly 13 years.

“I stand up for science because science saved my life,” Whitehead said.

Friday’s rally in Washington was at the Lincoln Memorial, in the shadow of a statue of the president who created the nearby National Academy of Sciences in 1863.

From 11 million kilometers away from Earth, NASA proved science could divert potentially planet-killing asteroids, former NASA Administrator Bill Nelson said. On his space shuttle flight nearly 40 years ago, he looked down to Earth and had a “sense of awe that you want to be a better steward of what we’ve been given,” he said.

The rallies were organized mostly by graduate students and early career scientists. Dozens of other protests were also planned around the world, including more than 30 in France, Delawalla said.

Protesters gathered around City Hall in Philadelphia, home to prestigious, internationally recognized health care institutions and where 1 in 6 doctors in the U.S. has received medical training.

“As a doctor, I’m standing up for all of my transgender, nonbinary patients who are also being targeted,” said Cedric Bien-Gund, an infectious disease doctor at the University of Pennsylvania. “There’s been a lot of fear and silencing, both among our patients and among all our staff. And it’s really disheartening to see.”

The U.S. Department of Justice dropped a proposal Friday to force Alphabet’s Google to sell its investments in artificial intelligence companies, including OpenAI competitor Anthropic, to boost competition in online search.

The DOJ and a coalition of 38 state attorneys general still seek a court order requiring Google to sell its Chrome browser and take other measures aimed at addressing what a judge said was Google’s illegal search monopoly, according to court papers filed in Washington.

“The American dream is about higher values than just cheap goods and ‘free’ online services. These values include freedom of speech, freedom of association, freedom to innovate, and freedom to compete in a market undistorted by the controlling hand of a monopolist,” prosecutors wrote.

A spokesperson for Google said the “sweeping proposals continue to go miles beyond the court’s decision, and would harm America’s consumers, economy and national security.”

A spokesperson for Anthropic did not immediately respond to a request for comment.

U.S. President Donald Trump has said he would continue a crackdown on Big Tech, which began during his first term and continued into former U.S. President Joe Biden’s administration. Trump has tapped veteran antitrust attorney Gail Slater to lead the DOJ’s efforts.

Google holds a minority stake worth billions of dollars in Anthropic. Losing the investment would give a competitive advantage to OpenAI and its partner Microsoft, Anthropic wrote to the court in February.

Evidence prosecutors obtained since making their draft recommendation in November showed a risk that banning Google from AI investments “could cause unintended consequences in the evolving AI space,” they said in the final proposal Friday. They asked that Google be required to give prior notice to the government about future investments in generative AI.

Google, which has said it will appeal, has made its own proposal that would loosen agreements with Apple and others to set Google as the default search engine on new devices. U.S. District Judge Amit Mehta has scheduled a trial on the proposals for April.

The blockbuster case is one of several U.S. antitrust cases against Big Tech companies. Apple, Meta Platforms and Amazon.com also face allegations of maintaining illegal monopolies in their respective markets.

Since Trump’s reelection, Google has sought to make the case that the DOJ’s approach in the case would hobble the company’s ability to compete in AI and “jeopardize America’s global economic and technological leadership.”

Many of the measures prosecutors proposed in November remain intact with a few tweaks.

For example, a requirement that Google share search query data with competitors now says that Google can charge a marginal fee for access and that the competitors must not pose a national security risk.

The proposal drew statements of support from Democratic and Republican attorneys general as well as the Alphabet Workers Union-CWA.

CAIRO — Nearly 100 people died of cholera in two weeks since the waterborne disease outbreak began in Sudan’s White Nile State, an international aid group said.

Doctors Without Borders — also known as Medecins Sans Frontieres, or MSF — said Thursday that 2,700 people have contracted the disease since Feb. 20, including 92 people who died.

Of the cholera patients who died, 18 were children, including five no older than 5 and five others no older than 9, Marta Cazorla, MSF emergency coordinator for Sudan, told The Associated Press.

Sudan plunged into war nearly two years ago when tensions simmered between the Sudanese army and its rival paramilitary Rapid Support Forces group, or RSF, with battles in Khartoum and elsewhere across the country.

RSF launched intense attacks last month in the White Nile State, killing hundreds of civilians, including infants. The Sudanese military announced at the time that it made advances there, cutting crucial supply routes to RSF.

During the RSF attacks in the state on Feb. 16, the group fired a projectile that hit the Rabak power plant, causing a mass power outage and triggering the latest wave of cholera, according to MSF. Subsequently, people in the area had to rely mainly on water obtained from donkey carts because water pumps were no longer operational.

“Attacks on critical infrastructure have long-term detrimental effects on the health of vulnerable communities,” Cazorla said.

The cholera outbreak in the state peaked between Feb. 20 and 24, when patients and their families rushed to Kosti Teaching Hospital, overwhelming the facility beyond its capacity, according to MSF. Most patients were severely dehydrated. MSF provided 25 tons of logistical items such as beds and tents to Kosti to help absorb more cholera patients.

Cazorla said that numbers in the cholera treatment center had been declining and were at low levels until this latest outbreak.

The White Nile State Health Ministry responded to the outbreak by providing the community access to clean water and banning the use of donkey carts to transport water. Health officials also administered a vaccination campaign when the outbreak began.

Sudan’s health ministry said Tuesday that there were 57,135 cholera cases, including 1,506 deaths, across 12 of the 18 states in Sudan. The cholera outbreak was officially declared on Aug. 12 by the health ministry after a new wave of cases was reported starting July 22.

The war in Sudan has killed at least 20,000 people, though the number is likely far higher. The war has driven more than 14 million people from their homes, pushed parts of the country into famine and caused disease outbreaks.
