New Magnetic Soap Could Revolutionize Cleaning
Scientists at a British university have created the world's first soap sensitive to magnetic fields. The product could could calm concerns over the use of soaps in oil-spill clean ups.
What's the Latest Development?
British scientists have developed a magnetic soap which can be controlled after it is added to another solution, representing a potentially big gain when it comes to cleaning industrial zones and spilled toxins. The soap was created "by dissolving iron in a range of inert surfactant materials composed of chloride and bromide ions, very similar to those found in everyday mouthwash or fabric conditioner. The addition of the iron creates metallic centres within the soap particles."
What's the Big Idea?
Whenever systems are developed that respond only to outside stimuli, such as soap that responds to magnets, a breakthrough is achieved since the system will work only when it is needed to. The soap's selective response "allows a range of properties, such as its electrical conductivity, melting point, the size and shape of aggregates and how readily its dissolves in water to be altered by a simple magnetic on and off switch." An easily controllable soap could aid in environmental clean ups, such as oil spills, and water treatment.

According to TwoFold CEO Alison McMahon, a leader who doesn't care (or can't pretend to care) about his or her employees isn't much of a leader at all.
Why do people quit their jobs? Surely, there are a ton of factors: money, hours, location, lack of interest, etc. For Alison McMahon, an HR specialist and the CEO of TwoFold, the biggest reason employees jump ship is that they're tired of working for lousy bosses.
By and large, she says, people are willing to put up with certain negatives as long as they enjoy who they're working for. When that's just not the case, there's no reason to stick around:
Nine times out of ten, when an employee says they're leaving for more money, it's simply not true. It's just too uncomfortable to tell the truth.
Whether that's true is certainly debatable, though it's not a stretch to say that an inconsiderate and/or incompetent boss isn't much of a leader. If you run an organization or company, your values and actions need to guide and inspire your team. When you fail to do that, you set the table for poor productivity and turnover.
McMahon offers a few suggestions for those who want to hone their leadership abilities, though it seems that these things are more innate qualities than acquired skills. For example, actually caring about your workers or not depending wholly on HR thinking they can do your job for you.
It's the nature of promotions that, inevitably, a good employee without leadership skills will get thrust into a supervisory position. McMahon says this is a chronic problem that many organizations need to avoid, or at least make the time to properly evaluate and assist with the transition.
But since they often don't, they end up with uninspired workers. And uninspired workers who don't have a reason to stay won't stick around for long.
