Seven singing males were observed in Foping and seven more in Changqing National Nature Reserves – which almost equals the total number of individuals observed of this species since its discovery in the late 19th century. Nearly all of the birds were on mountain slopes at 2400–2500 meters above sea level in large, dense expanses of bamboo in open coniferous and mixed coniferous-broadleaved forest.

In the late 19th and early 20th centuries, about 10 Blackthroats were collected at two localities in the Gansu and Shaanxi provinces during the breeding season (May–August). Since then, there have been only a handful of mostly unconfirmed records from Sichuan and Yunnan provinces, China, from presumed breeding areas or on migration, including a few individuals found in bird markets . The most recent record is of a bird that was photographed on migration in the campus of the Sichuan University on 2 May 2011 . In addition, one individual has been caught in Thailand in winter.The Blackthroat resembles a European Robin Erithacus rubecula in size and
The song is distinctive, and consists of rather short, quick, varied strophes that include both whistles and harsh notes. The strophes are delivered at a fairly slow, even pace. Several individuals were sound recorded in 2011, and two of these recordings are now made freely available. This will facilitate future surveys of this enigmatic bird species.Contacts

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
