It has been busy week in the world of travel.
Hotel offerings continue to get better with the New York Marriott Marquis’s $39mn makeover. The windy city will see two iconic properties as the Radisson Blu makes its US debut with a aquatic skyscraper, the Radisson Blu Aqua Hotel Chicago and Langham announced plans for the Langham Chicago in the iconic IBM building. At the Waldorf Astoria, the trendy, lush new Guerlain Spa has reopened to pamper its guests.

Bad breath has never been more than a disgusting nuisance before. Now, Researchers at the University of Wisconsin-Madison have fashioned into being a device that uses human breath to generate electricity! Engineers Xudong Wang, Chengliang Sun and Jian Shi developed a material known as polyvinylidene fluoride (PVDF) that produces an electric charge whenever low-speed airflow passes over it, causing it to vibrate. The vibrations aide in electricity generation by creating piezoelectricity.
With the human race forever piling up Co2 emissions in the environment, researchers today are racing against time to develop Co2-soaking sponges that could help remove the smoky toxins from smokestack emissions and the like. These sponges use metal-organic frameworks however, most of which are made from crude oil and contain toxic metals. Now, the guys at the Illinois' Northwestern University have come up with a way to soak in Co2 that not only keeps the air clean, but strangely seems to satisfy your hunger too! Made from sugar, salt and alcohol, this sponge is a cleaner MOF that the ones developed before, and given the fact that it uses edible items to manufacture, it’s completely consumable!
