Soil solarization, a process that uses solar radiation to rid the soil of pests, is most common in regions with high solar radiation and high temperatures during the summer season. An alternative to soil fumigation, the process is used either alone or in combination with fumigants. To accomplish solarization, solar radiation is used to passively heat moist soil covered with clear plastic sheeting, with the goal of increasing soil temperatures to the point where they are lethal to soilborne organisms. The effectiveness of solarization is based on the actual maximum soil temperature reached and the amount of time the high temperatures can be sustained.
Survivors of stroke or other neurological conditions such as spinal cord injuries, traumatic brain injuries and Parkinson’s disease often struggle with mobility. To regain their motor functions, these patients are required to undergo physical therapy sessions. A team of researchers from the National University of Singapore’s (NUS) Faculty of Engineering has invented a novel robotic walker that helps patients carry out therapy sessions to regain their leg movements and natural gait. The system also increases productivity of physiotherapists and improves the quality of rehabilitation sessions.
Worldwide, drought conditions, extreme temperatures, and high soil saline content all have negative effects on tomato crops. These natural processes reduce soil nutrient content and lifespan, result in reduced plant growth and yield, and ultimately translate to lower profits for tomato producers. As an alternative to unsustainable practices such as the use of synthetic fertilizers, producers are looking to environment-friendly soil ameliorants such as verimcompost leachate, an organic liquid produced from earthworm-digested material and casts that occur during the vermicomposting process.
Banks are increasingly issuing ‘CoCo’ bonds to boost the levels of equity they hold. In a crisis situation, bondholders are forced to convert these bonds into a bank’s equity. To date, such bonds have been regarded only as a means of averting a crisis. A study by German economists now shows that if such bonds are badly constructed, they worsen a crisis instead of stabilizing the banking system.
CERN today launched its Open Data Portal where data from real collision events, produced by experiments at the Large Hadron Collider (LHC) will for the first time be made openly available to all. It is expected that these data will be of high value for the research community, and also be used for education purposes.
Just a few years ago, crocodilians – crocodiles, alligators and their less-known relatives – were mostly thought of as slow, lazy, and outright stupid animals. You may have thought something like that yourself the last time you were in a zoo and saw them lying still for hours, making people wonder if they were alive or made of plastic.
The thing everyone seems to talk about with the moon landings is the idea of the whole world stopping to watch. It was a mission that overcame nationalism, it wasn’t "America" putting a man on the moon, it was "Us" – humankind. With Rosetta, the whole world not only watched but they were part of a real-time conversation with mission control.
In many parts of the world, potatoes are a reliable dietary staple. However, potato plants also produce the toxins solanine and chaconine, which can protect growing sprouts from potential predators such as insects and fungi. These toxins, known as steroidal glycoalkaloids (SGAs), occur at very low levels in the edible tubers, but their levels in green skin and sprouts can be highly poisonous and even deadly to humans.
The cohesin molecule ensures the proper distribution of DNA during cell division. Scientists at the Research Institute of Molecular Pathology (IMP) in Vienna can now prove the concept of its carabiner-like function by visualizing for the first time the open form of the complex. The journal Science publishes the new findings in its current issue.
Researchers from laboratories at Géosciences Rennes (CNRS/Université de Rennes 1), Géosciences Montpellier (CNRS/Université de Montpellier 2) and Institut de Physique du Globe de Paris (CNRS/IPGP/Université Paris Diderot), in collaboration with a scientist in Taiwan, have shown that surface processes, i.e. erosion and sedimentation, may trigger shallow earthquakes (less than five kilometers deep) and favor the rupture of large deep earthquakes up to the surface. Although plate tectonics was generally thought to be the only persistent mechanism able to influence fault activity, it appears that surface processes also increase stresses on active faults, such as those in Taiwan, one of the world’s most seismic regions. The work is published in Nature Communications on 21 November 2014.
A terrestrial laser scanning technique that allows the structure of vegetation to be 3D-mapped to the millimetre is more accurate in determining the biomass of trees and carbon stocks in forests than current methods, according to new research involving UCL.
Last week, China and the United States announced an ambitious climate agreement aimed at reducing carbon emissions in both countries, a pledge that marks the first time that China has agreed to stop its growing emissions. Leaders of both nations hope the agreement will lead to a global consensus on emissions reduction, with one senior official in the Obama administration saying that the deal "will signal to countries around the world that this negotiation has serious legs and there is a real chance of this coming together."
Powered lower limb prosthetics hold promise for improving the mobility of amputees, but errors in the technology may also cause some users to stumble or fall. New research examines exactly what happens when these technologies fail, with the goal of developing a new generation of more robust powered prostheses.

Yawuru Country Managers have found a spectacled hare wallaby (Lagorchestes conspicillatus) population, a species which for the last decade was feared to be locally extinct at Roebuck Plains, adjacent to Broome.
Faking photographs is not a new phenomenon. The Cottingley Fairies seemed convincing to some in 1917, just as the images recently broadcast on Russian television, purporting to be satellite images showing the MH17 airliner being fired upon by a jet fighter, may have convinced others.
Invisibility cloaks can make objects invisible not just to light in the visible part of the spectrum, but to many other physical excitations. These include acoustic waves, matter waves, heat flux, and infrared or ultraviolet electromagnetic (EM) waves. But so far, any single invisibility cloak can manipulate only one of these types of excitations.
Quantitatively, nitrogen is one of the most important nutrients for the growth of plant organisms – from simple green algae to highly developed flowering plants. Nitrogen supply is essential for the development of all cell components, and as a good supply results in faster plant growth, it is commonly used as a fertiliser in agriculture. Nitrogen is assimilated in the chloroplasts of plant cells to produce the amino acid glutamine. This molecule serves as a storage form and central distributor that feeds nitrogen into various metabolic pathways. Scientists from the research group of Professor Karl Forchhammer at the Interfaculty Institute for Microbiology and Infection Medicine have investigated how plants keep track of their nitrogen supply. In cooperation with Dr. Marcus Hartmann at the Max Planck Institute for Developmental Biology and colleagues from the University of St. Petersburg, they discovered that plants possess a sophisticated glutamine sensor. So-called PII signalling proteins act as a "fuel gauge" for the amount of available nitrogen by measuring the glutamine concentration. This information is then used by the plants to precisely control their growth.
At this point, the blockbuster movie Interstellar has created such a stir that one would almost have to be inside a black hole not to know about it. And while the science fiction thriller may have taken some liberties with science to make its Hollywood plot work, the imagery comes straight from science—National Science Foundation (NSF)-funded science, in fact.
Occasional erratic bursts southward of the East Australian Current (EAC) are thought to have moderated the weather of south-east Australia this autumn and winter and they continue to introduce tropical and sub-tropical marine species to Tasmanian waters.
There are plenty of body parts that don’t grow back when you lose them. Nails are an exception, and a new study published in the Proceedings of the National Academy of Sciences (PNAS) reveals some of the reasons why.
Employees who work at small, locally owned businesses have the highest level of loyalty to their employers—and for rural workers, size and ownership of their company figure even more into their commitment than job satisfaction does, according to Baylor University researchers.
At the Large Hadron Collider (LHC) in Europe, faster is better. Faster means more powerful particle collisions and looking deeper into the makeup of matter. However, other researchers are proclaiming not so fast. LHC may not have discovered the Higgs Boson, the boson that imparts mass to everything, the god particle as some have called it. While the Higgs Boson discovery in 2012 culminated with the awarding in December 2013 of the Nobel Prize to Peter Higgs and François Englert, a team of researchers has raised these doubts about the Higgs Boson in their paper published in the journal Physical Review D.

Google said it would offer Chinese developers a way to sell mobile applications outside of mainland China by giving them access to its Play Store, which runs on Android phones and tablets.
(Phys.org) —NASA’s Swift spacecraft lifted off aboard a Boeing Delta II rocket from Cape Canaveral Air Force Station, Fla., beginning its mission to study gamma-ray bursts and identify their origins. Gamma-ray bursts are the most luminous explosions in the cosmos. Most are thought to be triggered when the core of a massive star runs out of nuclear fuel, collapses under its own weight, and forms a black hole. The black hole then drives jets of particles that drill all the way through the collapsing star and erupt into space at nearly the speed of light.

Plants are under permanent attack by a multitude of pathogens. To win the battle against fungi, bacteria, viruses and other pathogens, they have developed a complex and effective immune system. And just as in humans, this can also overshoot its target when some of the plant’s own proteins are mistakenly identified as foreign. Such autoimmune reactions can lead to tissue defects and growth arrest, and is particularly apparent in hybrids, where two divergent immune systems meet. Scientists from the Max Planck Institute for Developmental Biology in Tübingen, Germany, have now pinpointed the most common culprits for autoimmunity. Surprisingly, these are components of the immune system itself, which are mistakenly recognized by other immune receptors as intruders.
(Phys.org) —Scientists have argued for half a century about the existence of a form of diamond called lonsdaleite, which is associated with impacts by meteorites and asteroids. A group of scientists based mostly at Arizona State University now show that what has been called lonsdaleite is in fact a structurally disordered form of ordinary diamond.

(Phys.org) —Many people are familiar with the natural compound known as propane, used often as fuel, but less is discussed about propylene (or propene), with which propane is closely tied.
A collection of toy figurines that will interact with a video game is Nintendo’s entry into an already flourishing market.
Despite the fact that 81% of Canadians accept that temperature on Earth is increasing, Université de Montréal researchers have revealed that Canadians are generally misinformed about the science of climate change and are divided over the construction of new oil pipelines. The researchers’ study also found that 70% of Canadians perceive significant changes in weather where they live; 60% believe that weather in Canada has been getting more extreme; and 87% believe these changes are somewhat or very likely the consequence of a warming planet.

(Phys.org) —UCLA researchers have developed a perovskite photodetector that could reduce manufacturing costs and improve the quality of medical and commercial light sensors.
California’s approval of a $7.5 billion water bond has bolstered prospects for expanding reservoirs and groundwater storage, but the drought-prone state can effectively use no more than a 15 percent increase in surface water storage capacity because of lack of water to fill it, according to a new analysis released Nov. 20.
Scientists at Freie Universität Berlin, the University of Tubingen, and the Swiss Federal Institute of Technology in Zurich (ETH) provide a new 3D model of the protein Bax, a key regulator of cell death. When active, Bax forms pores in the membranes of mitochondria, causing the release of proteins from the intermembrane space into the cytoplasm. This in turn triggers a series of operations ending in cell death, which are often impaired in cancer cells.
What began as a project looking at the statistics of galaxy distributions found an underlying pattern that could help astronomers learn how the universe evolved
Thousands of authors’ works enter the public domain each year, but only a small number of them end up being widely available. So how to choose the ones taking center-stage? And how well can a machine-learning algorithm rank the most notable authors in the world? Allen B. Riddell at Dartmouth College set out to deliver some answers and he published his work, "Public Domain Rank: Identifying Notable Individuals with the Wisdom of the Crowd", on the ArXiv server.
In order to distinguish self from other, the immune system processes proteins from inside and outside the body in different ways. A new study revises understanding of how the process works and sheds light on autoimmune disease.
