A large number of friends on Facebook may appear impressive but, according to a new report, the more social circles a person is linked to online the more likely social media will be a source of stress.
A report from the University of Edinburgh Business School has found that the more groups of people in someone's Facebook friends, the greater potential to cause offence. In particular, adding employers or parents resulted in the greatest increase in anxiety.
New research shows that concerns about governmental failure to act effectively and fairly in the aftermath of extreme weather events can affect the degree to which residents are willing to protect themselves.
Published in the journal Nature Climate Change, the findings of a team led by scientists at the University of Exeter could prove key to establishing how society should evolve to cope with more turbulent weather and more frequent mega storms.
Among the most important techniques developed in atomic physics over the past few years are methods that enable the storage and cooling of atoms and ions at temperatures just above absolute zero. Scientists from Bangalore and Mainz have now demonstrated in an experiment that captured ions can also be cooled through contact with cold atoms and may thus be stored in so-called ion traps in a stable condition for longer periods of time. This finding runs counter to predictions that ions would actually be heated through collisions with atoms.
MANHATTAN, Kan. -- The key to motivation in physical activity may be feeling inadequate. One Kansas State University researcher found that those who exercised with a teammate whom they perceived to be better increased their workout time and intensity by as much as 200 percent.
Brandon Irwin, assistant professor of kinesiology, was the principle investigator in a study that tested whether individuals engage in more intense physical activity when alone, with a virtual partner or competing against a teammate.
In nature processes such as the movement of fluids, the intensity of electromagnetic signals, chemical compositions, etc., are subject to random fluctuations which normally are called 'noise'. This noise is a source of energy and its utilisation for undertaking a task is a paradigm that nature has shown to be possible in certain cases.
Drained wetlands in Sweden account for the same amount of greenhouse gas emissions as Swedish industry. This is shown by a summary of research from the University of Gothenburg, Sweden and the Swedish University of Agricultural Sciences.
Forests and agricultural fields on drained previous wetlands make up between five and ten percent of Sweden's surface area. When these wetlands are drained, they become a significant source of greenhouse gas emissions.
Copenhagen. Climate change is affecting all regions in Europe, causing a wide range of impacts on society and the environment. Further impacts are expected in the future, potentially causing high damage costs, according to the latest assessment published by the European Environment Agency this week.
The shells of marine snails – known as pteropods – living in the seas around Antarctica are being dissolved by ocean acidification according to a new study published this week in the journal Nature Geoscience. These tiny animals are a valuable food source for fish and birds and play an important role in the oceanic carbon cycle*.
Metallic glass alloys (or liquid metals) are three times stronger than the best industrial steel, but can be molded into complex shapes with the same ease as plastic. These materials are highly resistant to scratching, denting, shattering and corrosion. So far, they have been used in a variety of products from golf clubs to aircraft components. And, some smartphone manufacturers are even looking to cast their next-generation phone cases out of it.
CAMBRIDGE, MA -- Each winter, wide swaths of the Arctic Ocean freeze to form sheets of sea ice that spread over millions of square miles. This ice acts as a massive sun visor for the Earth, reflecting solar radiation and shielding the planet from excessive warming.
The Arctic ice cover reaches its peak each year in mid-March, before shrinking with warmer spring temperatures. But over the last three decades, this winter ice cap has shrunk: Its annual maximum reached record lows, according to satellite observations, in 2007 and again in 2011.
Stretching across central Africa, the Congo Basin forest is the second largest tract of rainforest in the world and a lifeline for more than 60 million people – providing food and income for many remote communities, storing huge amounts of carbon, supporting unique ecosystems and regulating the flow of the major rivers across Central Africa. Yet the Congo's forests are being cleared at an alarming rate amid global demand for the continent's minerals, energy and wood resources.
It appears that it's not just us Brits who are fascinated with the UK weather.
A group of researchers from Germany has taken to investigating the potential changes in extreme rainfall patterns across the UK as a result of future global warming and has found that in some regions, the time of year when we see the heaviest rainfall is set to shift.
Millbrook, N.Y. -- In the northern hardwood forest, climate change is poised to reduce the viability of the maple syrup industry, spread wildlife diseases and tree pests, and change timber resources. And, according to a new BioScience paper just released by twenty-one scientists, without long-term studies at the local scale—we will be ill-prepared to predict and manage these effects.
Young girls can dance their way to better mental health. Symptoms like depression, stress, fatigue, and headaches are alleviated with regular dancing. This is shown in a study run by Anna Duberg, a physical therapist at Örebro University Hospital and a doctoral candidate at Örebro University in Sweden. Regular dance training can thereby be regarded as a strategy for preventing and treating low spirits and depression. Dance also brings enhanced self-esteem and a greater capacity to deal with everyday problems.
