A challenge to space scientists to better understand our hazardous near-Earth space environment has been set in a new study led by the University of Birmingham.

The research represents the first step towards new theories and methods that will help scientists predict and analyse the behaviour of particles in space.

It has implications for theoretical research, as well as for practical applications such as space weather forecasting.

The research focused on two bands of energetic particles in near earth space, referred to as the Radiation Belts, or the Van Allen Belts.

These particles are trapped within the Earth’s magnetosphere and can damage electronics on satellites and spacecraft passing through, as well as posing risks to astronauts.

Gene therapy may be the best hope for curing retinitis pigmentosa (RP), an inherited condition that usually leads to severe vision loss and blinds 1.5 million people worldwide.

But there’s a huge obstacle: RP can be caused by mutations in over 80 different genes. To treat most RP patients with gene therapy, researchers would have to create a therapy for each gene—a nearly impractical task using current gene therapy strategies.

A more universal treatment may be forthcoming...

In our current age of artificial intelligence, computers can generate their own “art” by way of diffusion models, iteratively adding structure to a noisy initial state until a clear image or video emerges.

Diffusion models have suddenly grabbed a seat at everyone’s table: Enter a few words and experience instantaneous, dopamine-spiking dreamscapes at the intersection of reality and fantasy...

Using observations made with the Gran Telescopio Canarias (GTC) a study led from the Instituto de Astrofísica de Canarias (IAC) and the Universidad Complutense de Madrid (UCM) has confirmed that the asteroid 2023 FW14, discovered last year, is accompanying the red planet in its journey round the sun, ahead of Mars and in the same orbit.

With this new member, the group of Trojans that accompany Mars has increased in number to 17. But it shows differences in its orbit and chemical composition which may indicate that it is a captured asteroid, of a primitive type. The results are published in Astronomy & Astrophysics.
