Scientists to Treat Disabling Headaches with Teflon Patch

Thousands of people suffering from a disabling headache condition could soon be cured by a patch of Teflon implanted inside the brain, The Daily Mail reported. The pioneering treatment is designed to block pain messages along a major nerve, and research suggests it is highly effective.

Data due to be published soon shows that nearly two-thirds of patients who had the procedure are now pain-free. The condition, known as short-lasting unilateral neuralgiform headache with conjunctival injection and tearing, or SUNCT, affects more than 10,000 Britons. It causes shooting pain on the side of the face, jaw and gums and often makes the eyes and nose stream. Sufferers are predominantly male and over 50.

It is not fully understood why SUNCT occurs, but it is thought to involve a disturbance in part of the brain linked to the trigeminal nerve, which controls sensations of pain in the face.
Julian Belsom, 50, from Folkestone, Kent, is among patients whose lives have been transformed by the operation.

He began suffering from pain in his jaw in 2014. It became so severe that he felt suicidal and was forced to quit his job as a night manager in a Tesco store.
The father-of-two, who lives with wife Annette, eventually had to sell the family home as they could no longer afford the mortgage.

He says of the condition: “It was like an electric shock and a bee sting at the same time. I was in constant pain every day. There was no respite and it stopped everything in my daily life.”

During the procedure, neurosurgeons remove a small piece of skull from behind the ear and carefully separate the trigeminal nerve, near the base of the brain, from the artery next to it.

They then place a small pad of polytetrafluoroethylene – the same substance used to coat Teflon non-stick pans – between the nerve and the artery, to keep them apart.

A coalition backed by Google, Stripe and Shopify will spend $1.7 million to buy carbon removal credits from three early stage firms on behalf of the tech giants to help scale up the nascent markets, an executive told Reuters.

The world is expected to need to suck between five and 10 billion tons a year of carbon emissions out of the atmosphere by mid-century to reach its climate goals, yet at the moment most technologies are small scale.

The coalition, called Frontier, is also backed by H&M Group, JPMorgan Chase and Salesforce, among others.

The group, which aggregates demand from its members, will spend $1.7 million to buy credits from US-firm Karbonetiq, Italy-based Limenet and Canadian firm pHathom.

By contracting to buy early, the firms are better able to hire, raise finance and get the technologies off the ground, said Hannah Bebbington, head of deployment at Frontier.

"It allows companies to demonstrate commercial viability," she said.

Frontier's support for these early stage firms, which aim to lock emissions away in the ocean or in rocks and industrial waste, marks its fifth series of commitments.

Frontier, which was set up in 2022, aims to invest at least $1 billion in carbon removal credits between 2022 and 2030. It has already committed $600 million, some on the series of pre-purchases and the bulk on a series of off-take agreements with larger firms. Last week, it agreed to pay $41 million for 116,000 tons from waste biomass firm Arbor.

For oceans, the aim is to increase the alkalinity of the water, helping it to lock away more carbon emissions. This is often done by adding "quicklime", made from limestone.

For the mineralization technologies, meanwhile, projects attempt to speed up the process whereby rocks and industrial waste naturally absorb carbon dioxide, for example by crushing up the material to create a larger surface area.

Bebbington said both technologies had the potential to be impactful because they could be scaled quickly and cheaply.

"We think (they) are extremely compelling from that really cheap at really large scale perspective."
