Injecting pollutants into the atmosphere to reflect the sun would be extremely dangerous, but the UK is funding field trials

Some years ago in the pages of the Guardian, we sounded the alarm about the increasing attention being paid to solar geoengineering – a barking mad scheme to cancel global heating by putting pollutants in the atmosphere that dim the sun by reflecting some sunlight back to space.

In one widely touted proposition, fleets of aircraft would continually inject sulphur compounds into the upper atmosphere, simulating the effects of a massive array of volcanoes erupting continuously. In essence, we have broken the climate by releasing gigatonnes of fossil-fuel carbon dioxide, and solar geoengineering proposes to “fix” it by breaking a very different part of the climate system.

Cladribine tablet for those with active multiple sclerosis will reduce hospital visits and free up appointments

Thousands of patients with multiple sclerosis (MS) in England are to become the first in Europe to benefit from a major roll out of an immunotherapy pill.

Current treatments involve regular trips to hospital, drug infusions, frequent injections and extensive monitoring, which add to the burden on patients and healthcare systems.

A former NOAA official says another round of ‘malicious’ layoffs will affect more than 1,000 additional employee

One simple exercise proved older adults can build and retain muscle – and caused a paradigm shift in science

In 1988, 712 people lived at the Hebrew Rehabilitation Center for the Aged, a Boston nursing home affectionately named “Hebrew rehab” by its residents and staff. The residents’ average age was 88, and three-quarters of them were women. Every resident had multiple medical conditions. Almost half required help to engage in the essential activities of daily life: getting out of bed, going to the bathroom, bathing, walking, eating. But they were survivors. Some had survived the Holocaust. Others fled the Cossacks. They all lived through the Great Depression.

They were ideal research subjects for Maria Fiatarone, a young doctor and faculty member in geriatric medicine at both Tufts and Harvard. In terrible shape, with lifetimes of practice overcoming great challenges: to Fiatarone, they were perfect.

Each year, hundreds of potentially world-changing treatments are discarded because scientists run out of cash. But where big pharma or altruists fear to tread, my friend and I have a solution. It’s repugnant, but it will work

Twenty miles outside Geneva, beneath the towering magnificence of a mountain called the Rock of Hell, is a long, pleasant road that runs past the Brocher mansion. Set in acres of gentle lawns and specimen trees, on the edge of the medieval village of Hermance, it is a blissful place. My friend Dominic Nutt and I have been trying to break in for years.

La Fondation Brocher is the world’s leading institute for research into “the ethical, social and legal implications of new medical developments”. It’s the bioethics equivalent of the Institute for Advanced Study in Princeton: only the admin staff and the cleaners are permanently employed here; academic fellowships last a maximum of four months. Billions of pounds’ worth of pharmaceuticals are influenced by the scholarly judgments that emerge from this idyllic lakeside building. Dom and I want to force entry because we’re advocates for patients, and we think we’ve solved a small corner of a major problem that’s holding back the discovery of new medicines. The trouble is, neither of us has a PhD – and in the rarefied world of academic medical ethics, that matters.

The Mars we know now is arid and dusty, with punishing radiation levels. But, as science correspondent Nicola Davis tells Madeleine Finlay, two new studies add weight to the idea that billions of years ago the red planet was a much wetter place. Nicola explains why researchers now think it was once home to sandy beaches, what a study looking into the type of rust on the planet has revealed about its damp past, and what all this might tell us about the former habitability of Mars

Mars once had an ocean with sandy beaches, researchers say
