As our dependence on mobile devices grows and we continue the shift to electric vehicles, there is a need to not only develop better performing batteries but find more accessible and sustainable materials with which to build them. To this end, researchers have now developed an anode for lithium-ion batteries using something those with allergies certainly wouldn't miss: pollen from bees and cattails.
Incandescent light bulbs may put out a warmer-looking, more familiar type of light than LEDs or compact fluorescents, but they're far less efficient – the majority of the energy they use is wasted, mainly in the form of heat. Technology may save them yet, however. Scientists at MIT and Purdue University have developed an ultra-efficient new incandescent bulb that reuses the heat it gives off, converting that heat into more light.
We have drugs to treat nasty conditions like irritable bowel syndrome and Crohn's disease, but unfortunately their effects are often blunted by little stumbling blocks known as the stomach and the small intestine. These body parts are prone to absorbing certain medications before they can do their best work. But a new type of capsule holds onto its payload until reaching the large intestine, making for more effective delivery.
Doing your hair and brushing your teeth are chores that may become a
little more interesting and fun with a new mirror that, besides
reflecting, can also display emails, news threads, tweets, public
transport times and all kinds of online data. That's because a student
team from the College of Science and College of Engineering at Purdue
University has created a mirror that doubles as an information
interface. Keeping up-to-date with bus schedules inspired the team to
come up with the info-mirror.
