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

Lethal combination: Drug cocktail turns off the juice to cancer cells

Smelling the forest – not the trees

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
Scientists at the University of Stuttgart and the Karlsruhe Institute of Technology (KIT) succeed in important further development on the way to quantum Computers.
Quantum computers one day should be able to solve certain computing problems much faster than a classical computer. One of the most promising approaches is...
