A new study has revealed that fungi, often seen as pests, play a crucial role policing biodiversity in rainforests.
The research, by scientists at Oxford University, the University of Exeter and Sheffield University, found that fungi regulate diversity in rainforests by making dominant species victims of their own success.
Fungi spread quickly between closely-packed plants of the same species, preventing them from dominating and enabling a wider range of species to flourish. (more…)
Periodically, Yale chemistry professor Robert Crabtree strolls through his laboratory, sometimes whistling, and pauses to ask the students who work with him: “Everybody happy?”
According to Ulrich Hintermair, who conducted research in his lab as a postdoctoral fellow for the past two-and-a-half years, Crabtree’s concern with his research team’s wellbeing is just one of many qualities that distinguish him as a mentor at Yale. (more…)
Genetic information provided by a large group of specially designed mice could pave the way to faster human health discoveries and transform the ways people battle and prevent disease.
In 15 papers published Feb. 16 in the Genetics Society of America journals Genetics and G3:Genes/Genomes/Genetics, researchers from North Carolina State University, the University of North Carolina at Chapel Hill, The Jackson Laboratory and other universities and labs across the globe highlight a new genetic resource that could aid development of more effective treatments for any number of human diseases.

A gene that influences the inflammatory response to infection may also predict the effectiveness of drug treatment for a deadly form of tuberculosis.
An international collaboration between researchers at the University of Washington in Seattle, Duke University, Harvard University, the Oxford University Clinical Research Unit in Vietnam and Kings College London reported these findings Feb. 3 in the journal Cell. (more…)
ANN ARBOR, Mich.— Why is the universe magnetized? It’s a question scientists have been asking for decades. Now, an international team of researchers including a University of Michigan professor have demonstrated that it could have happened spontaneously, as the prevailing theory suggests.
The findings are published in the Jan. 26 edition of Nature. Oxford University scientists led the research. (more…)
*New research reveals how the arrival of the first plants 470 million years ago triggered a series of ice ages. Led by the Universities of Exeter and Oxford, the study is published in Nature Geoscience.*
The team set out to identify the effects that the first land plants had on the climate during the Ordovician Period, which ended 444 million years ago. During this period the climate gradually cooled, leading to a series of ‘ice ages’. This global cooling was caused by a dramatic reduction in atmospheric carbon, which this research now suggests was triggered by the arrival of plants.
Among the first plants to grow on land were the ancestors of mosses that grow today. This study shows that they extracted minerals such as calcium, magnesium, phosphorus and iron from rocks in order to grow. In so doing, they caused chemical weathering of the Earth’s surface. This had a dramatic impact on the global carbon cycle and subsequently on the climate. It could also have led to a mass extinction of marine life. (more…)
Aspirin - to fight cancer. Image credit: Volker Mintzlaff
Or does it? Fresh research from Oxford University seems to reveal that a low dose of aspirin taken over a substantial period of time produces promising results, indicating that the death rates of many types of cancer reduce greatly. In fact, the evidence presented is staggering and if true, would be a medical breakthrough of exponential proportions.
Let us be optimistic, for cancer is a disease which has cut across most families around the globe. Few of us have not lost a grandparent, parent, uncle or aunt to this disease, in some cases even brothers, or worse still, nephews or nieces…or worse still, sons or daughters, grandsons and daughters. Now it seems there is good news which does not involve chemo-therapy or radio-therapy, which create many success stories but also many victims. (more…)
