The director of the team, Mr Joxerra Aihartza, took the first steps when he began drawing up a complete atlas of the distribution of bat species in the Autonomous Community of the Basque Country (CAV-EAE). There are now nine biologists on the team.
As Mr Egoitz Salsamendi, member of the team, explained, they took Mr Aihartza’s research as the starting point and, “from then on, the group specialised in analysing the choice of habitat and diet”. To this end, they mainly used radio-telemetry. “We have highly specialised radio transmitters – they have to be very small in order to attach them to the animals. When the transmitters are attached, we release the bats back into the cave and, when the next night they begin feeding, we can monitor them. In this way we know when and to what extent they move and what they feed on”.Long-fingered bats partial to fish
They thus showed that this species of bat eat fish but, as Joxerra Aihartza himself explained, it was needed to show that it was the bats themselves who were catching the fish: “We controlled their movements for a number of days using a tent where we had left fish and we observed that they did, in fact, catch live fish”. Their staple diet are the insects inhabiting the surface of the water, “but there is an ecological reason that explains this fishing behaviour: when the pools of water in a cave start drying up, the fish concentrate at their surface and they are easy to catch”, added Mr Salsamendi. Ostaizka Aizpurua, member of the team, has begun to write a PhD thesis on the species.Necessity for caves and suitable habitats
The biologist also underlined that the habitat is a fundamental factor, given that bats need a great variety and quantity of insects.
In this sense, Mr Aihartza pointed out that pine tree management and the use of pesticides such as Dimilin cause considerable damage, and not only affect the conservation of the bats: “Bats are very good indicators of the state of health of habitats. A prosperous habitat provides refuge to a prosperous community of bats. The protection of bats guarantees the protection of the habitat - each needs the other”.
In relation to this, and as requested by government bodies, the team carried out a number of management plans, but Mr Aihartza states that no notice has been taken of them: “The species continue as bad as before, or even worse, and this is our main concern”.Investigating virology
Mr Aihartza also mentioned “a large-scale project” for the coming years: “According to data revealed in recent years, a number of diseases have appeared in bats that substantially affect humans. For example, bats could be carriers of the African Ebola virus”. Thus, they are also studying, in conjunction with other teams, the virology of bats.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
