Theoretical physicist Peter Higgs, the namesake of the boson that was discovered in 2012, died on Monday, aged 94. Six decades ago, Higgs first suggested how an elementary particle of unusual properties could pervade the universe in the form of an invisible field, giving other elementary particles their masses. Half a century later, experiments confirmed the prediction and Higgs shared the Nobel prize for the discovery. Notoriously self-deprecating, Higgs was uncomfortable with fame and shunned the spotlight: he was inaccessible by e-mail or mobile phone. “Peter was a very special person, an immensely inspiring figure for physicists around the world, a man of rare modesty, a great teacher and someone who explained physics in a very simple yet profound way,” says Fabiola Gianotti, director-general of CERN.

On 4 July 2012, researchers at CERN’s Large Hadron Collider declared success in their long search for the Higgs boson. The elusive particle’s discovery filled in the last gap in the standard model — physicists’ best description of particles and forces — and opened a new window onto physics by providing a way to learn about the Higgs field and how it gives particles their masses. But many of the properties of the Higgs boson remain mysterious.

NOTABLE QUOTABLE

In 2013, Higgs told The Guardian that it’s unlikely he would have done his groundbreaking work under today’s ‘publish or perish’ culture. (5 min read)

In a surprise move, Iran has pardoned and released the last four members of a wildlife conservation group that were imprisoned since 2018. The four are part of a group of nine arrested and charged with espionage while carrying out research on Iran’s endangered Asiatic cheetah and Persian leopard. The group’s leader, sociologist Kavous Seyed-Emami, died in prison. The release is “very good news. But nothing can restore the lost years of life and the loss of Emami,” says Kaveh Madani, who was deputy head of Iran’s Department of Environment when he was arrested as part of the same operation.

Avi Wigderson has won what is considered the ‘Nobel Prize’ of computer science for his work on randomness in algorithms. With a series of groundbreaking studies in the 1990s, Wigderson helped to confirm that algorithms that make random choices to achieve their objectives are as accurate as conventional, deterministic algorithms. “I was extremely happy, and I didn’t expect this at all,” Wigderson says. “I’m getting so much love and appreciation from my community that I don’t need prizes.”

In 2019, conservationist Ripi Yanuar Fajar and four others observed what might have been a Javan tiger (Panthera tigris sondaica), which are thought to have gone extinct in the 1980s. Now it seems a strand of hair recovered by researcher Kalih Raksasewu from the location of the sighting 10 days later is a genetic match with a Javan tiger pelt held in a museum. “I wanted to emphasize that this wasn’t just about finding a strand of hair, but an encounter with the Javan tiger in which five people saw it,” says Kalih.

Features & opinion

Artificial intelligence (AI) systems can help researchers to understand how genetic differences affect people’s responses to drugs. Yet most genetic and clinical data comes from the global north, which can put the health of Africans at risk, writes a group of drug-discovery researchers. They suggest that AI models trained on huge amounts of data can be fine-tuned with information specific to African populations — an approach called transfer learning. The important thing is that scientists in Africa lead the way on these efforts, the group says.

Media engagement can open up unexpected opportunities for collaborations and skills development, says physical-activity researcher Ben Singh. Although scientists should court media attention responsibly — the ultimate goal is to inform the public — he suggests pitching published papers to relevant journalists and outlets, writing for websites such as The Conversation or using social media to connect with peers and the public. To avoid overly simplified coverage or misinterpretation of his work, he learnt to “articulate the actual objectives and limitations clearly up front during interviews, conferences and seminars”.

Monday’s solar eclipse was exciting for those lucky enough to be in its path — and free of cloud — as well as for scientists observing it. Thank you to everyone who’s shared their images with us!

Readers often get in touch about working for Nature, so I wanted to flag a paid opportunity for students and recent graduates in the UK, US and Germany to gain experience in research, education and science news publishing in Springer Nature’s journals, books or magazines. Applicants from all backgrounds are welcome to apply, especially candidates from historically underrepresented groups, including but not limited to Black people, Indigenous people and people of colour, people from socio-economically disadvantaged backgrounds, LGBTQ+ people, people from underrepresented social castes, religious minorities and people with a disability and/or a neurodivergent condition. Please find more information on the Springer Nature website.

Among those paying tribute to Peter Higgs, I enjoyed this gem from science-mad comedian Dara Ó Briain: he got Higgs to sign off on a fun joke involving a boson in a jar.

Tonight, I’ll be raising a glass of London Pride, which I’m reliably informed was Higgs’s favourite tipple (and is luckily my favourite beer, too). Tomorrow I hope I return to an inbox filled with your feedback on this newsletter: please e-mail us at [email protected].

science mourns giant of particle physics

[ad_1]

Few scientists have enjoyed as much fame in recent years as British theoretical physicist Peter Higgs, the namesake of the boson that was discovered in 2012, who died on 8 April, aged 94.

It was 60 years ago when Higgs first suggested how an elementary particle of unusual properties could pervade the universe in the form of an invisible field, giving other elementary particles their masses. Several other physicists independently thought of this mechanism around the same time, including François Englert, now at the Free University of Brussels. The particle was a crucial element of the theoretical edifice that physicists were building in those years,which later became known as the standard model of particles and fields.

Two separate experiments at the Large Hadron Collider (LHC) near Geneva, Switzerland — ATLAS and the CMS — confirmed Higgs’ predictions when they announced the discovery of the Higgs boson half a century later. It was the last missing component of the standard model, and Higgs and Englert shared a Nobel Prize in 2013 for predicting its existence. Physicists at the LHC continue to learn about the properties of the Higgs boson, but some researchers say that only a dedicated collider that can produce the particle in copious amounts — dubbed a ‘Higgs factory’ — will enable them to gain a profound understanding of its role.

Inspiring figure

“Besides his outstanding contributions to particle physics, Peter was a very special person, an immensely inspiring figure for physicists around the world, a man of rare modesty, a great teacher and someone who explained physics in a very simple yet profound way,” said Fabiola Gianotti, director-general of CERN in an obituary posted on the organization’s website; Gianotti who announced the Higgs boson’s discovery to the world at CERN. “I am very saddened, and I will miss him sorely.”

Many physicists took to X, formerly Twitter, to pay tribute to Higgs and share their favourite memories of him. “RIP to Peter Higgs. The search for the Higgs boson was my primary focus for the first part of my career. He was a very humble man that contributed something immensely deep to our understanding of the universe,” posted Kyle Cranmer, physicist at the University of Wisconsin Madison and previously a senior member of the Higgs search team at the CMS.

I was fortunate to meet Peter Higgs in 2013 (days after the Nobel prize announcement). He was modest as he told a group of PhD students the history of the boson theory. Afterwards, I was very lucky to get my copy of the New York Times with the discovery signed by him,” said Clara Nellist, a physicist at the University of Amsterdam and a member of the ATLAS particle-discovery collaboration.

A career highlight was helping Peter into a cab after the Collider exhibition launch @sciencemuseum in 2013 with a carrier bag of special-edition beer marking his recent Nobel,” posted Harry Cliff, a physicist at the University of Cambridge, UK.

“He disliked the limelight but was comfortable with friends and colleagues,” Frank Close, a physicist at the University of Oxford, UK, and author of the book Elusive: How Peter Higgs Solved the Mystery of Mass (2022), said in a statement to the UK Science Media Centre. “His boson took 48 years to appear, and when the Nobel was announced, he had disappeared to his favourite sea food bar in Leith.”

An exciting journey

Higgs’ work continues to be of fundamental importance, said physicist Sinead Farrington at the University of Edinburgh. “We’re still on an exciting journey to figure out whether some further predictions are true, namely whether the Higgs boson interacts with itself in the predicted way, and whether it might decay to other beyond the Standard Model particles,” she told the Science Media Centre.

For physicist and science writer Matt Strassler, Higgs’ death represents ‘the end of an era’. “Higgs was a fortunate scientist: he lived to see his insight at age 30 turn up in experiments 50 years later,” he posted on X. “His role and influence in our understanding of the #universe will be remembered for millennia.”
