Will the Tour de France prologue in Utrecht get the winner it deserves? New aerodynamic research shows that riders in a time trial can save vital seconds by riding closer to the following team car. Over a short distance like the prologue of the Tour de France, that can save as much as 6 seconds: enough to make the difference between winning and losing.
Katie HerzogOn a recent visit to the White House, famous person Cara Delevingne left a message for one of its would-be inhabitants on her Instagram. Let's see how you feel about climate change in 10 years Mr Trump! It is painfully real. Also, can Donald Trump do this???? #itrumptrump #ichallengetrump #climatechangeexistsfool A photo posted by Cara Delevingne (@caradelevingne) on Jan 20, 2016 at 4:47pm PST “Let’s see how you feel about climate change in 10 years Mr Trump!” Delevingne captioned the photo, which showed the supermodel impersonating a crow (?) somewhere in the White House. “It is painfully real,” she continued. Delevingne also included the hashtags “#itrumptrump,” “#ichallengetrump” and “#climatechangeexistsfool.” And for those of you who don’t speak…
Renewable energy can be stored for less with a new organic aqueous flow battery, which uses inexpensive and readily available materials. The new battery is expected to cost about 60 percent less than today’s standard flow batteries.
adminPerovskite solar cells are cheaper to make than traditional silicon cells and their electricity conversion efficiency is improving rapidly. To be commercially viable, perovskite cells need to scale up from lab size. Researchers report a method for making perovskite cells larger while maintaining efficiency.
New findings have overturned a scientific dogma that stood for decades, by showing that potassium can work with graphite in a potassium-ion battery — a discovery that could pose a challenge and more sustainable, less costly alternative to the widely used lithium-ion battery.
Four years ago, having just published a book of non-fiction, I was drawn to the idea of experimenting with fiction writing. Specifically, I wanted to write a dystopian novel that was a cross between Logan’s Run and Blade Runner. Climate change and the eventual draconian measures to keep it under control – declining country-assigned population caps, for one – would drive the narrative through characters who, in an increasingly carbon-constrained world, suddenly and unexpectedly found themselves among society’s most vulnerable. Working title: Cap and Cull. Why venture into fiction? It seemed to me like a better way to educate people about an otherwise complex – and I expect for most – boring topic. I tried to do this in my book Mad Like Tesla. …
adminThe bacterium Acidithiobacillus ferrooxidans can take electrons needed for growth directly from an electrode power source when iron—its already known source of energy—is absent, new research shows. The study shows that A. ferrooxidans can use direct uptake of electrons from an electrode to fuel the same metabolic pathway that is activated by the oxidation of diffusible iron ions.
