Fermi at Five Years

This compilation summarizes the wide range of science from the first five years of NASA’s Fermi Gamma-ray Space Telescope. Fermi is a NASA observatory designed to reveal the high-energy universe in never-before-seen detail. Launched in 2008, Fermi continues to give astronomers a unique tool for exploring high-energy processes associated with solar flares, spinning neutron stars, outbursts from black holes, exploding stars, supernova remnants and energetic particles to gain insight into how the universe works.

Fermi detects gamma rays, the most powerful form of light, with energies thousands to billions of times greater than the visible spectrum.

The mission has discovered pulsars, proved that supernova remnants can accelerate particles to near the speed of light, monitored eruptions of black holes in distant galaxies, and found giant bubbles linked to the central black hole in our own galaxy.

From blazars to thunderstorms, from dark matter to supernova remnants, catch the highlights of NASA Fermi’s first five years in space.

Theoretical physics: The origins of space and time

Many researchers believe that physics will not be complete until it can explain not just the behaviour of space and time, but where these entities come from.
Finding that one huge theory is a daunting challenge. Nature explores some promising lines of attack — as well as some of the emerging ideas about how to test these concepts (see 'The fabric of reality').

Ternary Flame
This image shows a ternary flame system with a Santoro burner below a ring burner. The steady soot column generated by the acetylene diffusion flame passes into the hydrogen ring flame, where it is oxidized. This allows soot oxidation to be studied in the absence of soot formation. The camera is a Nikon D100 digital still camera at 6.1 megapixels. This research is supported by NSF.

brian skerry photographs the results of commercial bluefin tuna fishing in the mediterranean. the world wildlife fund estimates that each year, 4.4 million sharks and 90,000 turtles are unintentionally caught as bycatch from unregulated commercial tuna fisheries using long lines and drift nets. a shark caught in a net will suffocate to death. shark numbers have declined by as much as 80 per cent worldwide, with a third of all species now threatened by extinction (pew charitable trusts)

3D Printing Glasses for Better Custom Fit

While fashion brands such as Warby Parker have been able to cut the price of their glasses frames by designing them in-house, consumers still need to pick from the range of preset designs offered. Recognizing that everyone’s face is unique, Protos Eyewear is a new startup that uses 3D printing to tailor each pair to the individual.
Having recently reached its target of USD 25,000 on its Crowdhoster site, Protos currently offers 24 different styles of frame that can be altered on the fly to cater for each customer’s needs. The frames are made of material that is light, strong and flexible, offering a quality feel while also being durable. Customers send two photographs of themselves when ordering a pair – one head-on and one side profile – that help the team to tweak each design to fit their face perfectly. Currently the Protos designs are only available in black although the startup hopes to add color options in the near future.
