Reducing the amount of fat in lamb amongst the Navarra variety of sheep in order to breed weightier animals, suitable for market demands and with a lower production cost for the farmer, is the aim of the project being developed by a research team from Navarre Public University’s Department of Agricultural Production and Department of Health Sciences.
The Navarre breed – previously known as Rasa Aragonesa – is found in the midlands region of Navarre and the extensive Ebro river basin region in the same territory. This ovine breed has some 420,000 heads which are basically given over to the production of “ternasco” meat type of lambs, slaughtered at three months when they are about 23-25 kilos of live weight.
The fundamental reason why these lambs are slaughtered at an early age (with corresponding low weights) is to avoid an excessive fatty state which, on the one hand, increases the cost of the feeding and fattening process and, on the other, puts a brake on the sale and consumption of dressed carcasses, due to high fat content and strong ovine taste.

Researchers from Sweden's Chalmers University of Technology and the University of Gothenburg present a new method which can double the energy of a proton beam produced by laser-based particle accelerators. The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.
Proton therapy involves firing a beam of accelerated protons at cancerous tumours, killing them through irradiation. But the equipment needed is so large and...
A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
