The UK’s legal cannabis market is booming – so why can’t this talented artist get any to treat his epilepsy? | Kojo Koram

Companies have rushed to supply the drug as a wellness treatment, but patients with serious illnesses aren’t able to get NHS prescriptions In 2022, a prodigiously talented young artist named Louis Petit was preparing to return to the UK, having been effectively exiled in the Netherlands as a teenager so he could access the medical cannabis he needed to control his epilepsy.

Cryosphere faces permanent damage when world overshoots 1.5C, scientists warn

UN-backed report finds even temporary rises above Paris agreement target could cause harm to glaciers and polar ice sheets Earth’s icy regions face such dangerous melting that global heating should be brought back below 1C after an inevitable period of overshooting global temperature targets, a UN report has found. Permanent and widespread losses of snow and ice expose a “persistent myth” that overshooting the 1.5C target of the Paris climate agreement – to 2C or 3C – could be manageable or even preferable to urgent cuts to emissions, the report found.

Was there hope for his young nephew , whose cancer had spread to the brain? Sadly, “no”, I said. But today, for such patients, there are options that were unimaginable back then. Recently, researchers at the European Society For Medical Oncology presented the latest chapter results from a randomised controlled trial of a bespoke cancer vaccine for patients with high-risk melanoma.

A job that changed me: I ran observatory tours as a student. An eight-year-old’s question taught me two important lessons

I thought the explanation I’d given about black holes was family-friendly. But, after what she had said, I had to rethink my examples Read more in the a job that changed me series In the first year of my science degree, I was fortunate to land a job as an astronomy guide at the Sydney Observatory. In my role, I would lead tour groups of about 20 people. We’d look at stars and planets through telescopes.

But that is what researchers are claiming to have discovered after analysing the hind leg bones of a small, meat-eating dinosaur called an Aratasaurus that lived and died in what is now north-eastern Brazil 115m years ago.
