Margaret Thatcher and the Evolution of Face RecognitionResearch from Emory University this week shows that we, and our ancestors, have been recognising faces in much the same way for 30 million years or more. By watching how Rhesus Macaques respond to a well known optical illusion called the Thatcher effect, professor Robert Hampton and colleagues were...
Serial killer sharksScientists have shed light on how those iconic ocean predators, great white sharks, go about catching their prey. It turns out they have something in common with human serial killers. Great white sharks lurk in spots that don’t just guarantee them the best chance of encountering seals but they try ...
In-Flight Mind ReadingIn a first study of its kind, researchers have recorded what’s going on in a pigeon’s brain during flight. Writing in the journal Current Biology, researchers at the University of Zurich wanted to know if familiar landmarks could be associated with changes in brain activity. The exact methods th...
Flying dolphinsScientists have uncovered the secret behind some dolphin’s amazing aquatic acrobatics: they have flippers that work in the same way as delta wing, those characteristic triangular-shaped wings on fighter jet planes, or that feat of 20th century engineering, Concord. So, dolphins can literally fly thr...
Freezing batteriesWe have a look at the chemistry of batteries and what happens if you cool them down. |
Racing Green - Electric and Hybrid SupercarsElectric and hybrid cars do have a bit of an image problem. Many people think they're a bit slow, a bit goody, goody, perhaps a bit worthy, but this week, Meera Senthilingam visited Imperial College London to find out how electric and hybrid cars could soon rival modern petrol hungry muscle cars....
Bipolar Batteries could be BetterSo far, we’ve heard that electric cars have a great deal of potential but they're held back by their weight, capacity and the expense of their batteries. So new types of batteries are actually essential to seeing more electric cars on the road...
Filling Up with AlgaeNow, electric cars are not the only option we have for sustainable personal transport. Already, there are a number of vehicles on the roads that use biodiesel and that’s diesel that doesn’t come from fossil fuel but from living creatures, from living plants. Now, Anna Stephenson is a PhD student a...
How do I save carbon with a new car?With the budget introducing the £2000 subsidy to scrap old cars, I'm trying to figure out how much energy and carbon goes into the manufacture of a new car. Considering the increase in efficiency of the new car, how many miles would I have to drive to achieve an overall carbon saving?...nat cousins asked the Naked Scientists: That's not very high mileage! Your comment that 40,000 kilometres a year is a lot ... - nat cousins - 13th Jul 09
Well the United States (9,161,923* SQ Km) is roughly 37 times larger than the United Kingdom (244,820* SQ Km).
