Temperature influences how badly pesticides affect bees' behaviour, suggesting uncertain impacts under climate change, according to a new study.

Geologists from Utrecht, London and Granada have found the first direct proof of the largest known mega-flood that ever occurred on earth.

The abolition of daylight saving time is a frequently - and hotly - debated topic. Often, only the aspect of electricity consumption due to artificial lighting is considered. In a new study, researchers have analyzed whether daylight saving time also has an impact on the energy needed to heat and cool office buildings, and what role climate change might play in this. The results should delight supporters of daylight saving time.

"If you pick a spot in, say, a rainforest, and count the number of different species of lizards within 15 metres and you come up with a number," says Luke Mahler, "What determines that number?" Mahler is an assistant professor in the University of Toronto's department of ecology and evolutionary biology in the Faculty of Arts & Science.

Medicine & Science Climate protection and sustainability are among the major issues of the future. The concerns are also increasingly coming to the fore in the health sector. Anaesthesia, and intensive care in particular, contribute to greenhouse gas emissions through the use of pollutants such as anaesthetic gases and equipment such as heart-lung machines, which have a high energy consumption.

Cambridge scientists have come up with a system of measuring animal welfare that enables reliable comparison across different types of pig farming.

In the Forest Laboratory "Waldlabor" on Hönggerberg, researchers investigate the storage and transport processes of water in the forest. Recently they showed that forest-floor litter and deadwood have a far larger influence on the forest water balance than expected.

It was only the beginning of March, but the pollen count Naresh Kumar measured with one of his aerosol samplers came in at more than 1,500 grains per cubic meter of air. "Extremely high for this time of year, and it wasn't even the official start of spring,” said the professor of public health sciences at the University of Miami Miller School of Medicine.

Parasite treatments and preventatives we put on our pets are finding their way into UK waters in concentrations that are toxic to aquatic species.

A study by researchers at ETH Zurich shows for the first time how a relaxation of Swiss spatial planning policy would affect the locations of wind turbines. If the aim is to have as few wind turbines as possible in the Alps and in Switzerland in general, it would be worth considering using windy agricultural areas on the western Swiss Plateau.
