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.

As cancer treatments become more effective, we must ask: what is life like for the people who receive them? | Ranjana Srivastava
Many treatments are now extending lives but the measure of progress should not end with a scan or a survival curve Two decades ago, a dear friend called me in a trembling voice. 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.

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. If the skies were filled from horizon to horizon with clouds, we’d explore more of the universe through a 3D theatre. And to peer beyond what our telescopes could see, we’d pile inside the cosy

Fossilised red blood cells found in 115m-year-old dinosaur’s bone, say scientists
Chemical tests on Aratasaurus bone identify presence of heme, the organic compound that allows haemoglobin in blood to carry oxygen around body It could be the opening of a Jurassic Park rip-off: scientists examining ancient dinosaur bones find what appear to be fossilised red blood cells, and traces of the molecule that gives the beast’s blood its distinctive crimson hue. 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.
