A dangerous strain of bird flu is spreading in US livestockMediaMedium/Alamy Since Donald Trump assumed office in January, the leading US public health agency has pulled back preparations for a potential bird flu pandemic. But as it steps back, another government agency is stepping up. While the US Department of Health and Human Services (HHS) previously held regular briefings on its efforts to prevent a wider outbreak of a deadly bird flu virus called H5N1 in people, it largely stopped once Trump took office. It has also cancelled funding for a vaccine that would have targeted the virus. In contrast, the US Department of Agriculture (USDA) has escalated its fight against H5N1’s spread in poultry flocks and dairy herds, including by funding the development of livestock vaccines. This particular virus – a strain of avian influenza called H5N1 – poses a significant threat to humans, having killed about half of the roughly 1000 people worldwide who tested positive for it since 2003. While the pathogen spreads rapidly in birds, it is poorly adapted to infecting humans and isn’t known to transmit between people. But that could change if it acquires mutations that allow it to spread more easily among mammals – a risk that increases with each mammalian infection. The possibility of H5N1 evolving to become more dangerous to people has grown significantly since March 2024, when the virus jumped from migratory birds to dairy cows in Texas. More than 1,070 herds across 17 states have been affected since then. H5N1 also infects poultry, placing the virus in closer proximity to people. Since 2022, nearly 175 million domestic birds have been culled in the US due to H5N1, and almost all of the 71 people who have tested positive for it had direct contact with livestock.

Sign up to newsletter “We need to take this seriously because when [H5N1] constantly is spreading, it’s constantly spilling over into humans,” says Seema Lakdawala at Emory University in Georgia. The virus has already killed a person in the US and a child in Mexico this year. Still, cases have declined under Trump. The last recorded human case was in February, and the number of affected poultry flocks fell 95 per cent between then and June. Outbreaks in dairy herds have also stabilised. It isn’t clear what is behind the decline. Lakdawala believes it is partly due to a lull in bird migration, which reduces opportunities for the virus to spread from wild birds to livestock. It may also reflect efforts by the USDA to contain outbreaks on farms. In February, the USDA unveiled a $1 billion plan for tackling H5N1, including strengthening farmers’ defences against the virus, such as through free biosecurity assessments. Of the 150 facilities that have undergone assessment, only one has experienced an H5N1 outbreak. Under Trump, the USDA also continued its National Milk Testing Strategy, which mandates farms provide raw milk samples for influenza testing. If a farm is positive for H5N1, it must allow the USDA to monitor livestock and implement measures to contain the virus. The USDA launched the programme in December and has since ramped up participation to 45 states. “The National Milk Testing Strategy is a fantastic system,” says Erin Sorrell at Johns Hopkins University in Maryland. Along with the USDA’s efforts to improve biosecurity measures on farms, milk testing is crucial for containing the outbreak, says Sorrell. But while the USDA has bolstered its efforts against H5N1, the HHS doesn’t appear to have followed suit. In fact, the recent drop in human cases may reflect decreased surveillance due to workforce cuts, says Sorrell. In April, the HHS laid off about 10,000 employees, including 90 per cent of staff at the National Institute for Occupational Safety and Health, an office that helps investigate H5N1 outbreaks in farm workers. “There is an old saying that if you don’t test for something, you can’t find it,” says Sorrell. Yet a spokesperson for the US Centers for Disease Control and Prevention (CDC) says its guidance and surveillance efforts have not changed. “State and local health departments continue to monitor for illness in persons exposed to sick animals,” they told New Scientist. “CDC remains committed to rapidly communicating information as needed about H5N1.” The USDA and HHS also diverge on vaccination. While the USDA has allocated $100 million toward developing vaccines and other solutions for preventing H5N1’s spread in livestock, the HHS cancelled $776 million in contracts for influenza vaccine development. The contracts – terminated on 28 May – were with the pharmaceutical company Moderna to develop vaccines targeting flu subtypes, including H5N1, that could cause future pandemics. The news came the same day Moderna reported nearly 98 per cent of the roughly 300 participants who received two doses of the H5 vaccine in a clinical trial had antibody levels believed to be protective against the virus. The US has about five million H5N1 vaccine doses stockpiled, but these are made using eggs and cultured cells, which take longer to produce than mRNA-based vaccines like Moderna’s. The Moderna vaccine would have modernised the stockpile and enabled the government to rapidly produce vaccines in the event of a pandemic, says Sorrell. “It seems like a very effective platform and would have positioned the US and others to be on good footing if and when we needed a vaccine for our general public,” she says. The HHS cancelled the contracts due to concerns about mRNA vaccines, which Robert F Kennedy Jr – the country’s highest-ranking public health official – has previously cast doubt on. “The reality is that mRNA technology remains under-tested, and we are not going to spend taxpayer dollars repeating the mistakes of the last administration,” said HHS communications director Andrew Nixon in a statement to New Scientist. However, mRNA technology isn’t new. It has been in development for more than half a century and numerous clinical trials have shown mRNA vaccines are safe. While they do carry the risk of side effects – the majority of which are mild – this is true of almost every medical treatment. In a press release, Moderna said it would explore alternative funding paths for the programme. “My stance is that we should not be looking to take anything off the table, and that includes any type of vaccine regimen,” says Lakdawala. “Vaccines are the most effective way to counter an infectious disease,” says Sorrell. “And so having that in your arsenal and ready to go just give you more options.” Topics:

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology.Tech billionaires are making a risky bet with humanity’s future Sam Altman, Jeff Bezos, Elon Musk, and others may have slightly different goals, but their grand visions for the next decade and beyond are remarkably similar.They include aligning AI with the interests of humanity; creating an artificial superintelligence that will solve all the world’s most pressing problems; merging with that superintelligence to achieve immortality (or something close to it); establishing a permanent, self-­sustaining colony on Mars; and, ultimately, spreading out across the cosmos.Three features play a central role with powering these visions, says Adam Becker, a science writer and astrophysicist: an unshakable certainty that technology can solve any problem, a belief in the necessity of perpetual growth, and a quasi-religious obsession with transcending our physical and biological limits.In his timely new book, More Everything Forever: AI Overlords, Space Empires, and Silicon Valley’s Crusade to Control the Fate of Humanity, Becker reveals how these fantastical visions conceal a darker agenda.

Here’s what food and drug regulation might look like under the Trump administration Earlier this week, two new leaders of the US Food and Drug Administration published a list of priorities for the agency. Both Marty Makary and Vinay Prasad are controversial figures in the science community. They were generally highly respected academics until the covid pandemic, when their contrarian opinions on masking, vaccines, and lockdowns turned many of their colleagues off them. Given all this, along with recent mass firings of FDA employees, lots of people were pretty anxious to see what this list might include—and what we might expect the future of food and drug regulation in the US to look like. So let’s dive into the pair’s plans for new investigations, speedy approvals, and the “unleashing” of AI. —Jessica Hamzelou This article first appeared in The Checkup, MIT Technology Review’s weekly biotech newsletter.

One more thing The surprising barrier that keeps us from building the housing we needIt’s a tough time to try and buy a home in America. From the beginning of the pandemic to early 2024, US home prices rose by 47%. In large swaths of the country, buying a home is no longer a possibility even for those with middle-class incomes. For many, that marks the end of an American dream built around owning a house. Over the same time, rents have gone up 26%.The reason for the current rise in the cost of housing is clear to most economists: a lack of supply. Simply put, we don’t build enough houses and apartments, and we haven’t for years. But the reality is that even if we ease the endless permitting delays and begin cutting red tape, we will still be faced with a distressing fact: The construction industry is not very efficient when it comes to building stuff.

US Secretary of Health and Human Services Robert F Kennedy JrTasos Katopodis/Getty One of the top vaccine experts at the US Centers for Disease Control and Prevention (CDC), Lakshmi Panagiotakopoulos, resigned on 4 June – a week after Robert F Kennedy Jr announced that covid-19 vaccines would no longer be recommended for most children and pregnancies. The announcement set off several days of confusion around who will have access to covid-19 vaccines in the US going forward. In practice, there hasn’t been a drastic change to access, though there will probably be new obstacles for parents hoping to vaccinate their children. Still, Kennedy’s announcement signals a troubling circumvention of public health norms. “My career in public health and vaccinology started with a deep-seated desire to help the most vulnerable members of our population, and that is not something I am able to continue doing in this role,” said Panagiotakopoulos in an email to colleagues obtained by Reuters. Panagiotakopoulos supported the Advisory Committee on Immunization Practices (ACIP), which has advised the CDC on vaccine recommendations since 1964. But last week, Kennedy – the country’s highest-ranking public health official – upended this decades-long precedent. “I couldn’t be more pleased to announce that, as of today, the covid vaccine for healthy children and healthy pregnant woman has been removed from the CDC recommended immunisation schedule,” he said in a video posted to the social media platform X on 27 May. Despite his directive, the CDC has, so far, only made minor changes to its guidance on covid-19 vaccines. Instead of recommending them for children outright, it now recommends vaccination “based on shared clinical decision-making”. In other words, parents should talk with a doctor before deciding. It isn’t clear how this will affect access to these vaccines in every scenario, but it could make it more difficult for children to get a shot at pharmacies.

While its website still recommends a covid-19 shot during pregnancy, a note at the top says, “this page will be updated to align with the updated immunization schedule.” Kennedy’s announcement contradicts the stances of major public health organisations, too. Both the American College of Obstetricians and Gynecologists (ACOG) and the American Academy of Pediatrics (APP) have come out opposing it. “The CDC and HHS encourage individuals to talk with their healthcare provider about any personal medical decision,” an HHS spokesperson told New Scientist. “Under the leadership of Secretary Kennedy, HHS is restoring the doctor-patient relationship.” However, Linda Eckert at the University of Washington in Seattle says the conflicting messages are confusing for people. “It opens up disinformation opportunities. It undermines confidence in vaccination in general,” she says. “I can’t imagine it won’t decrease immunisation rates overall.” Research has repeatedly shown covid-19 vaccination in adolescence and pregnancy is safe and effective. In fact, Martin Makary, the head of the US Food and Drug Administration (FDA), listed pregnancy as a risk factor for severe covid-19 a week before Kennedy’s announcement, further convoluting the government’s public health messaging. Kennedy’s announcement is in line with some other countries’ covid policies. For example, Australia and the UK don’t recommend covid-19 vaccines for children unless they are at risk of severe illness. They also don’t recommend covid-19 vaccination during pregnancy if someone is already vaccinated. Asma Khalil, a member of the UK Joint Committee on Vaccination and Immunisation, says the UK’s decision was based on the reduced risk of the omicron variant, the cost-effectiveness of vaccination and high population immunity. However, these factors can vary across countries. The UK population also tends to have better access to healthcare than the US, says Eckert. “These decisions need to carefully consider the risks and benefits relative to the national population,” says Khalil. The HHS didn’t answer New Scientist’s questions about whether a similar analysis guided Kennedy’s decision-making. What is maybe most troubling, however, is the precedent Kennedy’s announcement sets. The ACIP – an independent group of public health experts – was expected to vote on proposed changes to covid-19 vaccine recommendations later this month. But Kennedy’s decision has bypassed this process. “This style of decision-making – by individuals versus going through experts who are carefully vetted for conflicts of interest, who carefully look at the data – this has never happened in our country,” says Eckert. “We’re in uncharted territory.” She worries the move could pave the way for Kennedy to chip away at other vaccine recommendations. “I know there are a lot of vaccines he has been actively against in his career,” she says. Kennedy has previously blamed vaccines for autism and falsely claimed that the polio vaccine caused more deaths than it averted. “What it speaks to is the fact that [Kennedy] does not see value in these vaccines and is going to do everything he can to try and devalue them in the minds of the public and make them harder to receive,” says Amesh Adalja at Johns Hopkins University.

Manus has kick-started an AI agent boom in China Last year, China saw a boom in foundation models, the do-everything large language models that underpin the AI revolution. This year, the focus has shifted to AI agents—systems that are less about responding to users’ queries and more about autonomously accomplishing things for them.There are now a host of Chinese startups building these general-purpose digital tools, which can answer emails, browse the internet to plan vacations, and even design an interactive website. Many of these have emerged in just the last two months, following in the footsteps of Manus—a general AI agent that sparked weeks of social media frenzy for invite codes after its limited-release launch in early March.As the race to define what a useful AI agent looks like unfolds, a mix of ambitious startups and entrenched tech giants are now testing how these tools might actually work in practice—and for whom.

Despite the system’s indispensable nature, the GPS signal is easily suppressed or disrupted by everything from space weather to 5G cell towers to phone-size jammers worth a few tens of dollars.

Some new research suggests that people with heart conditions have better outcomes when they are more hopeful and optimistic. Hopelessness, on the other hand, is associated with a significantly higher risk of death. The findings build upon decades of fascinating research into the phenomenon of the placebo effect. Our beliefs and expectations about a medicine (or a sham treatment) can change the way it works. The placebo effect’s “evil twin,” the nocebo effect, is just as powerful—negative thinking has been linked to real symptoms. Researchers are still trying to understand the connection between body and mind, and how our thoughts can influence our physiology. In the meantime, many are developing ways to harness it in hospital settings. Is it possible for a doctor to prescribe hope? Read the full story.
