Atmospheric chemistry on paper
Normally computers speed up calculations. But with his new pen-and-paper formula Kevin Heng of the University of Bern gets his results thousands of times faster than using conventional computer codes. The astrophysicist calculates the abundances of molecules (known as atmospheric chemistry) in exoplanetary atmospheres. Ultimately, deciphering the abundances of molecules allows us to interpret if features in a spectrum are due to physics, geology or biology.

Weak bees make strong colonies
Colonies of the Eastern honey bee, the original host of parasitic Varroa destructor mites, survive infestations that are fatal to Western honey bees. A research team from Agroscope and the Institute of Bee Health at the University of Bern discovered that a large proportion of infested Eastern honey bee larvae die, prompting their elimination from the colony, together with that of their parasites. Counter-intuitively, weak individuals contribute to society survival by preventing the parasite to spread.
The gardener’s favourite ornaments deciphered
Garden petunias are amongst the most popular ornamental plants. For the first time, it has been possible to decipher the whole genome sequence of the wild ancestors of the garden petunia. The comprehensive study was published in the renowned specialist magazine Nature Plants last week. Cris Kuhlemeier from the Institute of Plant Sciences, who coordinated the study with over 50 participating researchers, explains why these research results are so important now.
Consensus in the Fight Against Colorectal Cancer
In colorectal cancer, the presence of invasive tumor cells at the advancing edge of the tumor can provide valuable information on prognosis.

New virus transmission route discovered in pigs
Japanese Encephalitis (JE) virus causes serious inflammation of the brain in people and fertility problems in pigs. Mosquitoes were previously the only known transmission route. However, the virus can also be spread from pig to pig by direct contact, and this could enable it to circulate in pigs during the mosquito-free winter season.
Aggressive cichlids: attack is the best form of defence
Researchers from Bern, England and Australia have observed the "Princess of Lake Tanganyika" cichlid in territorial conflicts and made an astonishing discovery; the conflicts distract the animals from their surrounding environments to such an extent that they notice lurking dangers only very late – yet the fish have a strategy which saves their lives: instead of trying to escape from predators, they defend themselves.

Honey bee queens highly vulnerable to two neonicotinoid insecticides
Throughout the northern hemisphere beekeepers have struggled to maintain adequate numbers of honey bee colonies for crop pollination and honey production due to dramatic increases in colony deaths each year. Recent surveys of beekeepers suggest that poor queen health is an important reason for these losses, but why queen health is now being affected is not understood. A research team from Bern, Switzerland and Wolfville, Canada has found that honey bee queens, which are crucial to colony functioning, are severely affected by two neonicotinoid insecticides.
When climate change is at the door
It is often suggested that we should emphasise the local effects of climate change in order to increase the willingness of the general populace to stand up for climate change mitigation. From a psychological point of view, however, it is clear that this is a significantly simplified concept of the effect. This is demonstrated in the work of the Bernese researcher Adrian Brügger whose work has just been published in the prestigious specialist journal "Nature Climate Change".

People who had come into close contact with someone recently infected, and who are therefore at particularly high risk, were vaccinated. Investigators from the University of Bern were heavily involved in designing the World Health Organization (WHO) «Ebola ça Suffit» vaccine trial.
Comets: Soft shell, hard core?
Comet Churyumov-Gerasimenko poses new riddles: Surface material measurements performed by the «Philae» landing module indicate that the near surface material might have changed since its formation. Up to now, many researchers had assumed that it has remained in virtually the same state since its formation about 4.5 billion years ago. The results of the study, in which researchers from the University of Bern were also involved, have been published in «Science» magazine.
Particulate matter from modern gasoline engines damages our lungs
Particulate matter from gasoline engines is harmful to our airways, regardless of whether the engines are a bit older or comply with recent EU standards.
