Killer bees are spreading across the US – and are being drawn to northern states because of warming temps
Africanized honey bees, infamously known as 'killer bees,' are rapidly spreading across the United States, having already been confirmed in 13 states from California and Arizona to Florida, Georgia, and as far east as Alabama.
These aggressive hybrids, originally bred in South America from East African and European honeybees, have been steadily migrating northward, fueled by climate change.
Unlike their European cousins, Africanized bees are highly defensive, capable of launching massive swarm attacks and delivering thousands of stings within minutes. They've even been reported to chase victims for nearly a mile, sometimes following cars and trucks, and are even capable of stinging through standard beekeeping suits.
The situation has turned deadly in recent months. A swarm killed a 75-year-old Texas man mowing his lawn last year, while other attacks have hospitalized people, pets, and animals, including horses.
In 2022, a 20-year-old Ohio man was stung 20,000 times while trimming tree branches and survived only after doctors placed him in a medically induced coma.
South Florida is a major hotspot for killer bees, reporting the densest populations and the highest number of incidents in the last quarter. Africanized bees have been found in Alabama, Georgia, Louisiana, and Mississippi, but they have a harder time surviving these wetter climates.
Experts warn that rising temperatures could push Africanized bees further north, especially in the western U.S., putting millions more Americans at risk by 2050.
'By 2050 or so, with increasing temperatures, we're going to see northward movement, mostly in the western half of the country,' Dr. Juliana Rangel, a bee expert in Texas who has been chased by the bees herself, told the Daily Mail.
Experts also say that when disturbed by lawn equipment, loud noises, or even pedestrians, these bees will swarm in overwhelming numbers and continue striking long after most other bees would retreat .
If you encounter a swarm, run away from the area immediately, cover your face, and seek shelter in a building or vehicle, as the bees usually remain outdoors.
Although dangerous, Africanized bees are also more disease-resistant than European honey bees, prompting some researchers to explore whether their resilience might benefit broader pollination efforts.

Member of RFK Jr's new vaccine panel withdraws over conflict of interest
A member of the health secretary Robert F Kennedy Jr's newly overhauled federal vaccine advisory panel withdrew after a conflict of interest review, a spokesperson has told the Guardian. Dr Michael Ross, who was involved in multiple private healthcare companies, withdrew after review of his financial holdings. Kennedy unilaterally fired all 17 members of the Centers for Disease Control and Prevention's (CDC) advisory committee on immunization practices (ACIP) in June, arguing they had too many conflicts of interest. Ross was among eight of Kennedy's ideological allies appointed to the committee, after the secretary argued the old members of the committee were subject to too many conflicts of interest. 'Yesterday, Dr Michael Ross decided to withdraw from serving on ACIP during the financial holdings review,' a spokesperson for the Department of Health and Human Services (HHS) said. 'The sacrifice to serve on ACIP varies from member to member, and we appreciate Dr Ross's willingness to go through this rigorous process.' The spokesperson made the comments after Guardian inquiries about conflict of interest disclosures for new members of ACIP. Although the Trump administration and Kennedy developed a conflict of interest tracker specifically for ACIP members, Kennedy's appointees have not been added. The HHS spokesperson did not respond to Guardian inquiries about when and where new, written conflict of interest disclosures would be published. Instead, the spokesperson said the department has, 'comprehensively reviewed all newly appointed ACIP members for conflicts of interests in accordance with federal law, regulations and departmental polices', and that the members were provided 'ethics training prior to discharging their duties'. The new members of the committee were asked to disclose conflicts of interest before the meeting began on Wednesday. The committee chair Dr Martin Kulldorff and committee member Dr Robert Malone omitted widely reported work in vaccine litigation, and nurse Vicky Pebsworth said she was 'asked to read' a statement disclosed ownership of a healthcare stock but said it was below the government ethics office threshold for reporting. Ethics review of the new members was also the subject of Senate testimony on Wednesday. Under questioning by the Democratic senator Patty Murray of Washington, the Trump nominee to head the CDC, Dr Susan Monarez, said she was 'not familiar whether or not the members that are participating in the meeting this week have or have not gone through the ethics review necessary to allow them to participate in those meetings'. 'If it is known that they have not gone through the ethics process and they issue recommendations, would you accept them as valid?' asked Murray. 'If they have not gone through an ethics approval process, they shouldn't be participating in the meetings,' said Monarez.

New toxic warning issued over disposable e-cigarettes
Researchers at the University of California at Davis found that popular disposable e-cigarettes are more toxic than traditional cigarettes, emitting higher levels of harmful metals. After just a few hundred puffs, some devices released neurotoxic lead and carcinogenic nickel and antimony, with one e-cigarette emitting more lead in a day than nearly 20 packs of traditional cigarettes. The study revealed that these toxins are either present in the e-liquid or leach extensively from components like leaded bronze alloy and heating coils. For daily users, emissions from some devices exceeded cancer risk limits for nickel and antimony, and health-risk thresholds for lead and nickel, posing risks like neurological damage and respiratory diseases. Despite most disposable e-cigarettes being illegal in the U.S., they remain available, with researchers emphasizing the urgent need for regulation enforcement due to the market outpacing scientific understanding and the high rate of use among teens and young adults.

CDC nominee Susan Monarez sidesteps questions about disagreements with RFK in Senate hearing
Susan Monarez, President Donald Trump 's pick to lead the U.S. Centers for Disease Control and Prevention, told senators Wednesday that she values vaccines, public health interventions and rigorous scientific evidence, but largely sidestepped questions about widespread cuts to the agency, elimination of programs and whether she disagreed with any of Health Secretary Robert F. Kennedy Jr.'s actions to date. 'The secretary is doing the important work of leading a complex agency,' Monarez told members of a Senate health committee that will decide whether to advance her nomination. Monarez, 50, is the first nominee for CDC director to require Senate confirmation. She was named acting director in January and the nominee for the post in March after Trump abruptly withdrew his first choice, David Weldon. Monarez is the former director of a federal biomedical research agency and a respected scientist, though she would be the first nonphysician to lead the CDC in decades. Monarez repeatedly said she had not been involved in decisions earlier this year to cut hundreds of staff and eliminate CDC programs, but that she would work to retain the agency's core functions and transition key programs to other parts of the Health and Human Services department. Her answers appeared to frustrate some senators, including Virginia Democrat Tim Kaine, who said he had no questions about her qualifications. 'I've got questions about your willingness to follow through on your values,' he said. In the two-hour hearing, Monarez was sharply questioned about Kennedy's recent move to fire all 17 members of a crucial committee that evaluates and recommends vaccines, his downplaying of the risks of measles during a nationwide outbreak and staffing cuts to a program that investigates lead poisoning in children. Sen. Bill Cassidy, a Louisiana Republican who is chairman of the committee, sought assurances about the scientific integrity of the CDC's Advisory Committee on Immunization Practices, which was reconstituted by Kennedy to include vaccine skeptics. 'Someone can speak as a critic, but there should be someone who's reviewing the overwhelming evidence of the safety of vaccines,' Cassidy said. Monarez said she strongly supported public health interventions, including immunizations, saying, 'I think vaccines save lives." 'The ACIP has a very vital role to play,' she added. 'And it must make sure that it is using science and evidence to drive that decision-making.' She vowed to prioritize innovation, 'evidence-based rapid decision-making' and clear communication at the $9.2 billion agency tasked with evaluating vaccines, monitoring diseases and watching for threats to Americans' health. Monarez declined to say whether she had disagreed with any of Kennedy's decisions regarding the agency to date, saying he has 'laid out a very clear vision.' 'I think he has prioritized key public health activities for preventing chronic diseases," she added. If Monarez is confirmed, it would end a stretch of confusion at the Atlanta-based CDC, where, for months, it wasn't clear who was running the agency. The acting director's role was filled in part by Matthew Buzzelli, the CDC's chief of staff who is a lawyer and political appointee with no medical experience. Monarez holds doctorate in microbiology and immunology from the University of Wisconsin, and her postdoctoral training was in microbiology and immunology at Stanford University. At CDC headquarters in Atlanta, employees have said Monarez was rarely heard from between late January and late March, when Trump nominated her. The CDC was created nearly 80 years ago to prevent the spread of malaria in the U.S. Its mission was later expanded, and it gradually became a global leader on infectious and chronic diseases and a go-to source of health information. ___ The Associated Press Health and Science Department receives support from the Howard Hughes Medical Institute's Department of Science Education and the Robert Wood Johnson Foundation.
