Monitoring chicken flock behaviour could help combat leading cause of food poisoning
A new technique that monitors the movement of chickens can be used to predict which flocks are at risk of becoming infected with Campylobacter - the most common bacterial source of food poisoning in humans in the UK.
Mexico's staggering homicide rate has taken a toll on the mortality rate for men -- and it could be even worse than the statistics indicate, a new study from the UCLA Fielding School of Public Health suggests.
ALBUQUERQUE, N.M. -- A new Sandia National Laboratories accelerator called Thor is expected to be 40 times more efficient than Sandia's Z machine, the world's largest and most powerful pulsed-power accelerator, in generating pressures to study materials under extreme conditions.
"Thor's magnetic field will reach about one million atmospheres, about the pressures at Earth's core," said David Reisman, lead theoretical physicist of the project.
PRINCETON, N.J.--Curbing school bullying has been a focal point for educators, administrators, policymakers and parents, but the answer may not lie within rules set by adults, according to new research led by Princeton University. Instead, the solution might actually be to have the students themselves, particularly those most connected to their peers, promote conflict resolution in school.
SHENYANG, CHINA - Nitrogen (N) is an essential nutrient for plant growth, and nitrogen fertilization - including the application of manures - is a major management strategy in agriculture across the globe. However, the overuse and misuse of manures has resulted in the accumulation of surplus N in soil and its eventual migration to soil layers and groundwater. The authors of a new study found that the environmental risks of manure applications in high-input greenhouse environments may outweigh the benefits, and recommend that the role of manures be reexamined.
New research into the potential for sparing land from food production to balance greenhouse gas emissions has shown that emissions from the UK farming industry could be largely offset by 2050. This could be achieved if the UK increased agricultural yields and coupled this with expanding the areas of natural forests and wetlands to match its European neighbours.
Methane is increasing in the atmosphere, but many sources are poorly understood. Lakes at high northern latitudes are such a source. However, this may change with a new study published in Nature Geoscience. By compiling previously reported measurements made at a total of 733 northern water bodies - from small ponds formed by beavers to large lakes formed by permafrost thaw or ice-sheets - researchers are able to more accurately estimate emissions over large scales.
Research performed by U.S. Department of Energy's Ames Laboratory Associate Scientist Durga Paudyal was recently featured on the cover of the November 13, 2015, issue of Physical Review Letters.
In his paper, "Complex Magnetism of Lanthanide Intermetallics and the Role of their Valence Electrons: Ab Initio Theory and Experiment," Paudyal and coauthors used electronic structure theory to explain how a mobile "electronic adhesive" helps localized electrons communicate and interact with one another.
Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to study the importance of adhesion in establishing contact between two patterned, yet elastic, surfaces. Nature is full of examples of amazing adjustable adhesion power, like the feet of geckos, covered in multiple hairs of decreasing size.
Fitness trackers like Fitbit, Fuelband, and Jawbone are all the rage and if they help individual people exercise more, great, but right now they are in the placebo world regarding evidence they work any better than anything else overall.
Researchers have developed a way to create ceramics using 3D printing that results in a strong material with little tendency to crack that can be fabricated into complex, curved and porous shapes. Ceramic materials offer many appealing qualities, including high-temperature stability, environmental resistance, and high strength. But unlike polymers and some metals, ceramic particles don't fuse together when heated. Thus, the few 3D printing techniques that have been developed for ceramics have slow production rates and involve additives that increase the material's tendency to crack.
Researchers say that the actions of individual farmers should be considered when studying and modelling strategies of pest control.
Research published in PLOS Computational Biology presents a model to understand the actions of humans and the dynamics of pest populations. The authors demonstrate this by using the example of the European corn borer, a moth whose larval phase is a major pest of maize.
The joint research team of Prof. Yoon Seok Jung (UNIST, School of Energy and Chemical Engineering) and Prof. Seng M. Oh (Seoul National University) discovered a new way to develop all-solid-state lithium batteries without a risk of conflagration or explosion. It is the method of melting the solid electrolyte and coating that melted electrolyte around the electrodes. This research outcome was introduced on Advanced Materials on December 22, 2015.
A fully renewable energy system is achievable and economically viable in Russia and Central Asia in 2030. Researchers from Lappeenranta University of Technology (LUT) modelled a renewable energy system for Russia and Central Asia. Results show that renewable energy is the cheapest option for the continent and can make Russia a very energy competitive region in the future.
Say hello to Nadine, a 'receptionist' at Nanyang Technological University (NTU Singapore). She is friendly, and will greet you back. Next time you meet her, she will remember your name and your previous conversation with her.
She looks almost like a human being, with soft skin and flowing brunette hair. She smiles when greeting you, looks at you in the eye when talking, and can also shake hands with you. And she is a humanoid.
