Bremerhaven/Germany, 24 June 2016. The Siberian permafrost regions include those areas of the Earth, which heat up very quickly in the course of climate change. Nevertheless, biologists are currently observing only a minimal response in forest composition. In the places where, when considering the air temperature, pine and spruce forests should be growing, Siberian larch trees are still thriving. The cause of this paradox has been tracked using million-year-old bee pollen by scientists at the Alfred Wegener Institute, the University of Cologne, and international partner institutions. The results suggest that the intensity of the ice ages determined how quick the vegetation adapted to warmer climate periods.

A University of Exeter scientist has helped develop an innovative mathematical model for exploring why some individuals evolve to be genetically programmed to be nice, while others stay nasty.

Dr Sasha Dall, Senior Lecturer in Mathematical Ecology, and a team of international colleagues have designed a new mathematical framework for examining social behaviour in a range of different species that will help advance our understanding of the evolution of sociality.

This government petition to call for a second EU referendum in the UK has suddenly become very popular. The number of signatures has now reached over 12% of the total votes cast in the referendum, over 25% of the Remain votes, and over 23% of the Leave votes cast. However the situation seems clear that having called this referendum, the government are committed to the result, and there is no provision for a second referendum. Should there be for future referendums however? And why are so many people signing this petition? Let's take a look.

One of the first clues pathologists look for in tissue from a newly diagnosed breast cancer patient is the estrogen receptor, a nuclear protein that converts hormonal messages in the bloodstream into instructions for the cell about how to behave. They also look for the presence of progesterone receptors, primarily to confirm that the estrogen receptor is active.

In the June 24 issue of Science Advances, however, researchers radically upgrade the significance of the progesterone receptor. They show that when exposed to estrogens and progestins, these receptor proteins interact with different sets of binding sites in the cell's chromosomes, with the progesterone receptor dramatically altering how estrogen receptors interact with the cell's DNA.

The elephantnose fish explores objects in its surroundings by using its eyes or its electrical sense - sometimes both together. Zoologists at the University of Bonn and a colleague from Oxford have now found out how complex the processing of these sensory impressions is. With its tiny brain, the fish achieves performance comparable to that of humans or mammals. The advance results have been published online in the "Proceedings of the National Academy of Sciences of the United States of America" (PNAS). The print issue will appear soon.

International researchers centered at Nagoya University use a highly sensitive technique to identify significantly more DNA sequence repeats in patients with schizophrenia than in control individuals, and outline a possible link between genome instability and disease.

Washington, DC - June 24, 2016 - Bacteria that have the potential to abet breast cancer are present in the breasts of cancer patients, while beneficial bacteria are more abundant in healthy breasts, where they may actually be protecting women from cancer, according to Gregor Reid, PhD, and his collaborators. These findings may lead ultimately to the use of probiotics to protect women against breast cancer. The research is published in the ahead of print June 24 in Applied and Environmental Microbiology, a journal of the American Society for Microbiology.

The top quark is the heaviest known subatomic particle we may call "elementary", i.e. one we describe as a point-like object; it weighs a full 66% more than the Higgs boson itself! Top was discovered in 1995 by the CDF and DZERO collaborations at the Fermilab Tevatron collider, which produced collisions between protons and antiprotons at an energy 7 times smaller than that of the proton-proton collisions now provided by the Large Hadron Collider at CERN.

Roughly 90 percent of the biggest black holes are dormant, meaning that they are not actively devouring matter and therefore not giving off any light or other radiation.

Yet dormant is not dead, so when a star wanders too close, the ensuing feeding frenzy - a tidal disruption event - sets off a spectacular fireworks show. 

Rice farming is a far older practice than we knew. The oldest evidence of domesticated rice in China has now been pushed back to 9,000 years ago, thanks to a team of archaeologists.
