In a plenary talk on Tuesday 17 April at the Royal Astronomical Society National Astronomy Meeting in Preston, Dr James Klimchuk of the Naval Research Laboratory in the USA will present the latest results from the STEREO and Hinode spacecraft, two missions that have been studying the Sun for the last few months.
STEREO is a NASA-led mission with substantial participation by scientists from the UK and other European countries. It consists of two spacecraft watching the Sun from different vantage points, that will eventually allow astronomers look at the whole of the region between the Sun and the Earth for the first time and eventually allow them to construct 3D images of the Sun. Hinode is a Japanese mission with collaboration from scientists in the US and UK. It orbits the Earth in a path that gives the probe a continuous view of the Sun.
One of the key objectives of the two missions is to study solar outbursts. These involve the sudden release of energy stored in the magnetic fields of the corona, the hot material that makes up the outer atmosphere of the Sun. The smallest events or nanoflares heat the corona to a temperature of millions of degrees and cause the emission of X-ray and ultra-violet radiation that changes the upper atmosphere of the Earth. The largest Coronal Mass Ejections (CMEs) are spectacular and can cause storms in the Earth’s magnetic field.
Together, STEREO and Hinode give astronomers the ability to watch CMEs all the way from the Sun to the Earth. Scientists can watch their evolution as they interact with the outflow of particles from the Sun (the solar wind) en-route to our planet. CMEs are the most dramatic ‘space weather’ events and can cause damage to technological systems such as power grids and communication and navigation networks. The severity of the impact of a CME depends on how it changes as it makes the journey across the inner Solar system and the new missions allow astronomers to better understand how these outbursts evolve.

Data storage using individual molecules

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...
What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
