First time accepted submitter irl_4795 (4020741) writes At the Mobile World Congress in Barcelona NXP Semiconductors will demonstrate Near Field Magnetic Induction technology in a truly wireless earbud including wireless audio streaming from ear to ear. From the article: “The wireless technology being used to enable truly wireless earbuds is based on Near Field Magnetic Induction (NFMI). NFMI features important properties such as ultra-low power consumption and the ability to create a very reliable network in and around the human body, with both high-quality audio and data streaming supported over small distances. An additional integration advantage is also that it requires few external components. NFMI is a short range technology and as such also creates a private network, making it is much less susceptible to interference than 2.4 GHz transceivers. Read more of this story at Slashdot.

So perhaps it’s unsurprising that eusocial animals like ants are also incredibly communicative — more so than we previously understood, according to a new study in Current Biology. Many ants begin communicating acoustically from a very young age, in fact, in such a way that scientists suggest may be very important to their survival. As explained in an article by Carrie Arnold at ScienceNow, scientists believed until only recently that ants communicated only through pheromones, leaving, for example, scent trails behind them for other ants to follow — hence the phenomenon of single-file marching ants. (They can also, newer research suggests, use magnetic and vibrational landmarks to guide themselves around.)” Read more of this story at Slashdot.
