With spring now fully sprung, a new study by University of Wisconsin–Madison researchers shows that buds burst earlier in dense urban areas than in their suburban and rural surroundings. This may be music to urban gardeners’ ears, but that tune could be alarming to some native and migratory birds and bugs.

A new analysis of global data related to wildfire, published by the Royal Society, reveals major misconceptions about wildfire and its social and economic impacts.

Long-term exposure to air pollution has been linked to an increased risk of heart disease, but the biological process has not been understood. A major, decade-long study of thousands of Americans  found that people living in areas with more outdoor pollution —even at lower levels common in the United States — accumulate deposits in the…

Over fifty percent of the United States energy comes from coal and petroleum based fuels. Powering a nation in which the average person uses the amount of energy in 15,370 lbs of coal or 165,033 sticks of dynamite in a year is not sustainable. When thinking of a solution, the well-known renewable energy source that…

Unlike the declining populations of many fish species, the number of cephalopods (octopus, cuttlefish and squid) has increased in the world's oceans over the past 60 years, a University of Adelaide study has found.The international team, led by researchers from the University's Environment Institute, compiled a global database of cephalopod catch rates to investigate long-term…

The UN intersessional negotiations on climate change (UNFCCC) which started in Bonn last week enter their second week with the big question – how to find and allocate by 2020 the $100bn as agreed in the Paris Agreement. Delegate Pavlos Georgiadis reports.The burning question for week two of these negotiations is how to raise and…

Immune cells play essential roles in the maintenance and repair of our bodies.  When we injure ourselves, immune cells mount a rapid inflammatory response to protect us against infection and help heal the damaged tissue. Lead researcher Dr Helen Weavers, from the Faculty of Biomedical Sciences said: “While this immune response is beneficial for human health, many…

For years, one of the major arguments that has been made against genetically engineered crops is the fear that, by tampering with a plant’s DNA, it could potentially cause health issues for consumers. It’s an understandable worry, however, the scientific consensus now seems to be undeniable: Whatever faults GMO crops may have, they are safe for human…

Climate change creates more shrub vegetation in barren, arctic ecosystems. A study at Lund University in Sweden shows that organisms, such as bacteria and fungi, are triggered to break down particularly nutritious dead parts of shrubbery. Meanwhile, the total amount of decomposition is reducing. This could have an inhibiting effect on global warming.

Fish can adjust to warmer ocean temperatures, but heat waves can still kill them, a team of researchers from Sweden, Norway and Australia reports in an article published this week in Nature Communications. "A species might adapt and grow well (in warmer waters) but once you get strong heat spells, the water temperature might reach lethal temperatures…
