Research from the University of Liverpool, published in Lancet Respiratory Medicine, identifies a genetic variant that could improve the safety and effectiveness of corticosteroids, drugs that are used to treat a range of common and rare conditions including asthma, and chronic obstructive pulmonary disease (COPD).
Piezoelectric materials, which generate an electric current when compressed or stretched, are familiar and widely used: lighters that spark when you press a switch, microphones, sensors, motors and all kinds of other devices. Now a group of physicists has found a material with a similar property, but for magnetism. This 'piezomagnetic' material changes its magnetic properties when put under mechanical strain.
The ability to generate spoken verbs in infinitive in a given time begins to worsen in the early stages of Alzheimer's disease (AD). Thus, the verb fluency test has been found to be a suitable neuropsychological tool for the detection of healthy aging people at risk of developing cognitive impairment, according to a recent research of the Research Center and Memory Clinic.

Dr Stefano Vanin was part of an international team working on discoveries at the Holocene age hunter-gatherer site at Takarkori in south-western Libya.
The achievements of three girls who received intensive therapy through the Virginia Tech Carilion Research Institute's Neuromotor Research Clinic based on innovative pediatric neurorehabilitation research have been documented in a report published in BMC Research Notes.
Article describes cause of chirping that signals loss of heat from fusion reactions.
Colorado State University researchers have completed a first-of-its-kind, peer-reviewed study that examines the demographics, physical environment and psychosocial aspects of working in the cannabis trade, which is now legal in some form in over half the United States, including Colorado. The study results were published in the American Journal of Industrial Medicine.
Everyone has experienced the awkward situation of meeting someone and then forgetting their name shortly after. Among older adults, this happens more often than not. Baycrest researchers have discovered a new method to resolve this problem by tapping into a natural memory change during aging.
While legal abortions in the US are safe, the likelihood that women will receive the type of abortion services that best meet their needs varies considerably depending on where they live, says a new report from the National Academies of Sciences, Engineering, and Medicine. In addition, the report notes, the vast majority of abortions can be provided safely in office-based settings.
Researchers have demonstrated how auxin, a hormone that controls many processes in plants, reaches its destination.
On the seafloor of the shallow coastal regions north of Siberia, microorganisms produce methane when they break down plant remains. If this greenhouse gas finds its way into the water, it can also become trapped in the sea ice that forms in these coastal waters.
Cities experienced 2.3 more assaults than average on days when hosting presidential campaign rallies for Donald Trump during the lead-up to the 2016 United States Presidential Election, according to a first of its kind study published today in Epidemiology by researchers in the Perelman School of Medicine at the University of Pennsylvania. Hillary Clinton rallies were not linked to any increase in assaults.
A novel quantum effect observed in a carbon nanotube film could lead to the development of near-infrared lasers and other optoelectronic devices, according to scientists at Rice University and Tokyo Metropolitan University.
Researchers investigated the diet of people buried in the Ii Hamina, Northern Finland, cemetery from the 15th to the 17th centuries by analysing isotopes in the bones of the deceased. Isotopes preserve information on the various nutrient sources used by humans during their lifetime. A study published in the Environmental Archaeology journal reveals that the dominant protein source was small fish, such as roach or Baltic herring.
The International Journal of Cancer has just published the results of an experimental therapy tested on mice. The research, led by the Signaling Lab research group of the UPV/EHU's Faculty of Medicine and Pharmacy and the Department of Pharmacology, Pharmacy and Pharmaceutical Technology of the University of Santiago de Compostela, achieved an 80% reduction in liver metastasis brought about by colon cancer.
US Army-funded researchers at Brandeis University have discovered a process for engineering next-generation soft materials with embedded chemical networks that mimic the behavior of neural tissue. The breakthrough material may lead to autonomous soft robotics, dual sensors and actuators for soft exoskeletons, or artificial skins.
Scientists at the Joint Research Centre, the European Commission's science and knowledge service, find that global warming has allowed disease-bearing insects to proliferate, increasing exposure to viral infections.
A research conducted by the UAB demonstrates that mice suffering from this disease also have substantial malfunctions in small blood vessels, important in nourishing different organs and tissues and in regulating blood pressure, and which mainly affects females. The study also demonstrates a correlation between the state of peripheral blood vessels and different levels of anxious behaviour, both in normal ageing and in those suffering from Alzheimer's disease.
From the second trimester of pregnancy, the future baby already shows signs of pain when given a harmful stimulus or as a response to stress. In response to this confirmation, the researchers indicate the need to anaesthetise the foetus during open foetal surgery, OFS.
Many tame domesticated animals have a different appearance compared to their relatives in the wild, for example white patches in their fur or shorter snouts. UZH researchers have now for the first time shown that wild house mice develop the same visible changes -- without selection, as a result of exposure to humans alone.
