7:54 PM | England Announces Ban On Smoking In Cars With Children On Board
On Wednesday (2/11), England’s House of Commons voted overwhelmingly in favor of a measure to ban smoking in cars carrying children under the age of 18. The new law, which will take effect on October 1, follows a similar measure announced by Wales last summer (Scotland is also considering adopting the policy). Those caught violating the new regulation will face fines of up to £50 – about $76. The ban is an attempt to protect young people from the dangers of […]

4:23 PM | Omni Wheel: Transform Any Bike Into An Electric-Powered Hybrid In 30 Minutes (Video)
New York-based electric bicycle company EVELO just unveiled their new “Omni Wheel”: a front-wheel equipped with a 35W electric motor to give riders a power boost. With a quick 30-minute installation, riders can “electrify” their bikes, removing the existing front tire and replacing it with the Omni Wheel. Once installed, the wheel is able to accurately sense your pedal movements and provide complimentary power at speeds up to 20 mph. The Omni […]

4:13 PM | Don't forget to find someone this Valentine's Day
Life is very tough -  Let's face it happily. As the most awkward day of the year approaches (that would be Valentine's Day, for those of you playing along at home), it's not unusual to reflect on whether or not we've made the right life decisions.But wouldn't it be nice if scientists had done the hard work for you and studied a whole bunch of people throughout their lives to work out the key to happiness? Well, actually, they already have, and the results are in, as Vanessa explains […]

3:16 PM | Math, buffers and H-H, revisited in the new curriculum
I think that there are (unfortunately) some useful, simple math things to know when it comes to buffers and H-H in the new AP chemistry curriculum. Obviously, it has always been crucial to know that when the ratio of weak acid to conjugate base (or weak base to conjugate acid) in a buffer solution is […]

7:51 AM | Secret revealed How Popcorn gets its pop
Popcorn is the funniest corn to cook, because it jumps and makes a ‘pop’ sound in our pans. It is extremely amusing, that much we’ve established. But exactly how does it work? French physicists Emmanuel Virot and Alexandre Ponomarenko from the École Polytechnique decided to find out. The only one capable of becoming popcorn available is everta variety of corn (Zea mays) and that because of its far more compact shell amongst of the available corn varieties. So the […]

1:19 AM | Obama Asks Congress to Authorize Three-Year Military Campaign Against ISIS
Earlier today, U.S. President Barack Obama submitted a formal proposal to Congress asking them to authorize a three-year military campaign against the terrorist group known as ISIS or ISIL. The President claims that his proposal, which would include some limited ground operations, would help the U.S. avoid a large-scale ground invasion and occupation. The request is somewhat symbolic however, when you consider that the United States has been carrying out airstrikes on ISIS positions […]

1:09 AM | Choosing between resonance and hybridization
A question came up on the College Board’s AP chemistry discussion group recently, that I have seen many times before (including many variations of the same), and that often confuses students. It usually looks something like this; The fact that the nitrogen-to-oxygen bond lengths in the nitrite ion are all the same, can be attributed […]

7:34 PM | The Great Backyard Bird Count and other Winter Citizen Science Projects
Titmouse braving the snow! ©Ross Feitlinger      As I mentioned in "See it? Share it!" last week, this weekend is the Great Backyard Bird Count, or GBBC. The GBBC is an annual bird counting project run by the Cornell lab and the Audubon Society. Participants watch birds for 15 minutes and contribute their findings. This is just one of the many great citizen science projects that run nationally, internationally and locally throughout the year. Just because it's cold does […]

4:09 PM | Japanese Theme Park Makes Plans To Build A Hotel Staffed 90% By Robots
The Huis Ten Bosch theme park, located in Japan’s Nagasaki Prefecture, has set plans to build a hotel that will be almost entirely staffed by robots. The hotel will be called the Henn-na Hotel, which translates to the “Strange Hotel”, because of its unusually high-tech environment. According to CNN… “We’re not sure if the robotic staff at a planned hotel in Japan will be tucking guests into their beds at night, but they’ll be […]

12:06 AM | United States Considering Supplying Arms to Ukraine As Tensions With Russia Rise
Russia has stepped into the global spotlight in the past year with their annexation of the Crimean peninsula and their continued military presence in eastern Ukraine. In response to these developments, the United States and the European Union imposed a number of sanctions on Moscow, crippling the Russian economy. The west hoped that by damaging Russia’s international trade with sanctions, they could encourage Russia to cease their involvement in Ukraine […]

8:37 PM | Google, Amazon and Microsoft Are Paying to Get Around Adblock Plus Filters
The internet is saturated with pesky, distracting and irritating ads, which is precisely why Adblock Plus – a service that blocks these ads – has been exploding in popularity recently, growing nearly 70% in just the past year. But while Adblock Plus certainly does an excellent job blocking ads from all sorts of sources, the service is also apparently catering to a small number of web giants who don’t want their advertisements […]

5:59 PM | Using multi-platform tools to support chemistry teaching - Part 1 (introduction)
This Spring term (for Northern Hemisphere readers) we are showcasing and promoting some of the many ways chemisry teachers can enhance their teaching with tools and resources that support a flexible, multi-platform approach. This is often described as BYOD, or 'Bring Your Own Device'. I think this is something of a misnomer, and centres attention on the hardware, rather than the myriad software tools and resources designed to be device-agnostic. To support this theme, we commissioned Peter […]
