8:00 AM | The Ocean and its Toys
The Cornish beaches where Lego keeps washing up [T]he container ship Tokio Express was hit by a wave described by its captain as a “once in a 100-year phenomenon”, tilting the ship 60 degrees one way, then 40 degrees back. As a result, 62 containers were lost overboard about 20 miles off Land’s End – [...]

7:24 AM | How nanostructure geometry affects polymer photovoltaic device efficiency
Conjugated polymer based organic photovoltaic (OPV) devices have been the subject of increasing research interest over the past years due to their potential of being light weight, mechanically flexible, semitransparent. To increase the efficiency of OPV, it is necessary to achieve a precisely controlled donor-acceptor phase separation within the short exciton diffusion length without dead ends, as well as a high hole mobility within the polymer. Now, researchers have demonstrated the effects of […]

4:00 AM | Burst radio veloci, un enigma astrofisico di origine cosmica
La scoperta di un burst radio veloce (Fast Radio Burst, FRB), durato cioè qualche frazione di secondo, ad opera degli astronomi che lavorano presso il radiotelescopio di Arecibo fornisce nuove evidenze sull’esistenza di impulsi ‘misteriosi’ che sembrano provenire dalle regioni più remote dell’Universo. Gli scienziati dell’osservatorio di Parkes in Australia hanno già registrato una manciata […]

11:20 PM | Clouds of climate change
I don't normally seek out space news that's this close to home; instead, I tend to lean towards powerful black holes and distant galaxies. But this topic happened to weird me out enough to merit a thorough investigation.Noctilucent clouds.  (Image credit: "Noctilucent clouds over Stockholm" by Kevin Cho (Kee Pil Cho) - Own work.) When I first started learning about these guys, they reminded me of the northern lights - a beautiful but elusive atmospheric […]

10:27 PM | Harvey's Voyage
Dr. Harvey Tananbaum at the Smithsonian's Castle Library in May 2006. (Credit: Jim Moran) On April 20, 2014, Harvey Tananbaum stepped down after 23 years as director of the Chandra X-ray Center (CXC). This event was duly noted in various press releases, but its significance may not have been widely appreciated. By almost any measure Harvey has been one of the most outstanding directors ever of a major astrophysical observatory. He was director of Chandra for longer than any other […]

8:31 PM | Chandra, me, and the number 23
A month or two after Chandra launched in July 1999, I was asked at a Chandra X-ray Center (CXC) senior staff meeting how long I actually expected Chandra to operate. I spontaneously responded: "23 years". Now that is a number not heard very frequently, so there were lots of quizzical looks indicating that an explanation was in order. Shortly after the launch, Pat Henry – an old friend and colleague from the 70's work on the Einstein Observatory – had written a congratulatory […]
