Magnetic

Exactly how some animals, such as birds, can detect magnetic fields remains a mystery. Now researchers in Japan may have found a crucial piece of the puzzle, making the first direct observations of live, unaltered cells responding to magnetic fields.

A new study led by researchers from University College London suggests that combining traditional chemotherapy with an experimental therapy that uses magnetic nanoparticles to heat tumor cells could significantly enhance the efficacy of both treatments.

Ordinarily, epoxies are cured by exposure to either heat or ultraviolet light. Both have their drawbacks, which are nicely avoided by a new epoxy that hardens when passed through a magnetic field to produce a similar bond using a fraction of the energy.

Magnetic tape may seem an antiquated data storage technology, but its density and capacity is still hard to beat for big data centers. Now, IBM and Fujifilm have created a prototype high-density tape cartridge with a record-breaking 580 TB capacity.

Scientists at the City University of Hong Kong have developed a new type of spray-on coating they say can give regular objects the capabilities of magnetically controlled robots, with particular potential in biomedical applications.

A persistent scientific mystery over the past century has been exactly how some animals seemingly have the ability to sense the Earth’s magnetic field. A team of researchers are suggesting the magnetic-sensing bacteria could be symbiotically generating this novel sense.

Astronomers have detected the strongest magnetic field ever observed in the universe. Studying X-ray signals from a neutron star, the team calculated that its magnetic field is tens of millions of times stronger than any created in a lab on Earth.

The excavation and disposal of landmines is a time- and labor-intensive business, so it can be quite a waste of resources if the detected object is not actually a mine. A new system could help, by reducing the number of mine-hunting errors.

It was just a couple of months ago that we heard about an implantable material that electrically stimulates bone cells, causing them to reproduce. Now, scientists have created a similar substance that utilizes magnetism.

Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. This could be a step towards making electronic components out of common materials that might not otherwise be suitable.

It goes without saying that as a chemist stirs a solution in their lab, they need to check how its characteristics change. A new "Smart Stirrer" has been designed with that in mind, as it automatically detects and reports transformations.

Flexible robotic surgical devices show a lot of promise, as they're able to move through delicate parts of the body without causing damage. Thanks to a new system, it could soon be cheaper, safer and easier to track where they are within the patient.
