Winter temperatures are on the rise and scientists note this change will actually increase a plant’s exposure to freezing temperatures
Scientists from Agriculture and Agri-Food Canada predict crops will be at a greater risk of winter damage in the future even though the climate will be warmer. Perennial forage crops are grown on more than 40% of the cultivated land in Eastern Canada and other regions of North America, where they constitute the backbone of the livestock industry. The study of the impact of this significant warming trend is published in the September-October issue of Agronomy Journal, published by the American Society of Agronomy.
The loss of snow cover due to warmer winter conditions will increase exposure of plants to freezing temperatures. The authors also conclude that the occurrence of above-freezing temperatures and loss of cold hardiness will increase with climate warming. Forage crops are also likely to enter the winter in a lower state of cold hardiness due to warmer fall temperatures. Winter temperatures are expected to increase by 2 to 6 degrees C over the next 50 years in Eastern Canada; however, survival of perennial crops over the winter months requires the right climatic conditions. Sub-freezing temperature, loss of cold hardiness due to warm periods, ice encasement, and soil heaving can result in frequent crop losses.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
