Visitors to aerospace engineer Haim Abramovich’s office at the Israel Institute of Technology, in Haifa, once asked if they could run a freight train over his latest invention. Abramovich didn’t blink: The visitors were from Israel’s National Road Company, and they wanted to know whether his piezoelectric material—which he developed to warp aerodynamic surfaces at the command of an electric current—would instead generate power if embedded beneath rumbling roads and rails.
Abramovich, who had just launched start-up Innowattech to develop wearable microgenerators for powering mobile devices, was convinced the road and track were better homes for his technology. So the company “turned around 180 degrees,” he recalls, and figured out how to embed piezoelectric material beneath a road. Now, along with several other inventive start-ups, Innowattech is poised to harvest some of the spare kinetic energy of the world’s moving vehicles—call it the kinetic surplus.

A 36-million-year-old fossilized penguin skeleton found on a cliff-face in Peru has given scientists insight into how penguin feathers, originally used for flight, adapted to swimming. The fossil, found by palaeontology student Ali Altamirano of the Museum of Natural History in Lima, contained intact pigments which researchers say mean that, instead of the black and white plumage of modern-day penguins, the ancient bird sported grey and reddish-brown feathers.

A new defence of the fossil Ida as a precursor to today’s primates, including humans, has emerged from the research team that last year bought and promoted the 47-million-year-old remains.
Ida, or Darwinius masillae, was described in 2009 by Jens Franzen at the Research Institute and Natural History Museum of Senckenberg in Frankfurt, Germany, and colleagues, who identified it as a haplorrhine, precursors to modern-day monkeys and apes. However, two studies by other groups since then citing evidence from a new fossil and an independent study of similar primate fossils concluded Ida was closer to the strepsirrhine branch, precursors to today’s lemurs, (see ‘Fossil primate challenges Ida’s place’).

The US Vaccine Injury Compensation Program (VICP) will pay over $1.5 million to the family of a child whose parents allege acquired autism after routine vaccinations in 2000. CBS called the payment to the family of Hannah Poling the “first court award in a vaccine-autism claim” (9 September 2010, CBS).
However, the payment does not acknowledge a vaccine-autism link.
