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.Continue ReadingCategory: Materials, ScienceTags: Nanyan… Continue reading Magnetically-activated epoxy bonds fast using a fraction of the energy
Magnetic tape may seem like a pretty antiquated data storage technology, but its density and capacity is still hard to beat for big data centers. Now, IBM and Fujifilm have teamed up to create a prototype high-density tape cartridge with a record-break… Continue reading New magnetic tape prototype breaks data density and capacity records
If you have a pile of old VHS tapes collecting dust in your attic or basement that you know you’ll never watch again, either because all of those movies are available on DVD or a streaming service, or because you haven’t had a working VCR since 2003, there might be …read more
By combining magnetic materials with magnetic fields, robotics researchers continue to develop machines that can be remotely manipulated in all kinds of useful ways, such as somersault through the colon or crawl through blood vessels to deliver drugs. … Continue reading Magnetic spray turns objects into robots that walk, roll and crawl
One of the most persistent scientific mysteries over the past century has been exactly how some organisms seemingly have the ability to sense the Earth’s magnetic field. Despite several hypotheses, and a large volume of research, there is still no conc… Continue reading Bacteria helps animals sense the Earth’s magnetic field, study speculates
Let’s say you’re stranded on a desert island and want to get the news from the outside world. You’ll have to build your own crystal radio, of course, but your parts bin is nowhere to be found and Digi-Key isn’t delivering. So you’ll need to MacGuyver some components. Capacitors are …read more

Astronomers have detected the strongest magnetic field ever observed in the universe. Studying powerful X-ray signals coming from a neutron star, the team calculated that its magnetic field is tens of millions of times stronger than any ever created in… Continue reading Astronomers detect strongest known magnetic field in the universe
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.Continue Rea… Continue reading VENUS tech more accurately detects mines by giving them a buzz
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.Continue ReadingCategory: Medica… Continue reading Silky material uses magnetic particles to regrow bone
Researchers have for the first time managed to use electricity to switch on magnetism in a material that’s normally non-magnetic. The find could be a step towards making electronic components out of common materials that might not otherwise be suitable… Continue reading Non-magnetic material made magnetic using electricity for the first time
