Currently, NIB magnets come in a range of strength grades, from N24, the lowest, to N55. A magnet rated N45 will have a 1.25 Tesla field. This is approaching the magnetic power of medical MRIs, which require a special, metal-free room. MRIs have magnets that run about 3 Teslas. All...

MS Drugs Need Time to Work When you’re sick, you want your medicine to work fast. Only some MS treatments do, and these are the ones that target symptoms. Some pain relieving medications, for example, can work pretty fast. So can drugs that shorten a relapse. For instance, if you ha...
Engineers are writing software to help brain researchers share and compare data. Software now analyzes, for instance, whether MRIs of Alzheimer's patients with different brain sizes and shapes have similar brain features. Are people with a certain brain architecture predisposed to bipolar disorder? Th...
