Trees call for help from birds and predatory insects
Trees call for help from birds and predatory insects
Chemical 'cry for help' from trees verified in a natural habitat for the first time Life Trees emit scents when attacked by caterpillars and other herbivores. They use these to attract predatory insects and even birds, thus getting rid of their pests. This had only been demonstrated in smaller scale experiments so far.

Neutral mutants can prevail in gut microbiota, enhancing diversity
Scientists at EPFL and Sorbonne propose a new model of the diversity and evolution of gut bacteria that shows how the gut environment helps neutral mutations become prevalent, with significant potential implications on health and metabolic diseases. -We are used to thinking of evolution as a very slow process, and this is definitely the case for large mammals etc,- says Professor Anne-Florence Bitbol at EPFL's School of Life Sciences.

Uncovering the underlying patterns in contemporary evolution
Uncovering the underlying patterns in contemporary evolution
Wild populations must continuously adapt to environmental changes or risk extinction. For more than fifty years, scientists have described instances of -rapid evolution- in specific populations as their traits (phenotypes) change in response to varying stressors. For example, Spanish clover has developed a tolerance for copper from the mine tailings in which it grows, and the horn size of Alberta bighorn sheep has decreased due to trophy hunting.

Disordered region of Src protein that regulates its oncogenic capacity
Disordered region of Src protein that regulates its oncogenic capacity
The Src protein takes part in the regulation of many physiological processes such as the survival, migration or cell adhesion as a response to stimuli received from several receptors of the membrane. Although it is demonstrated that its deregulation is involved in the proliferation of cancer in humans, many aspects of this function are still unknown, especially regarding its disordered region.

Unmuting the genome
Hereditary diseases as well as cancers and cardiovascular diseases may be associated with a phenomenon known as genomic imprinting, in which only the maternally or paternally inherited gene is active. An international research team involving scientists at the Technical University of Munich (TUM), the Max Planck Institute for Molecular Genetics (MPIMG) in Berlin and Harvard University in Cambridge (USA) has now investigated the mechanisms responsible for the deactivation of the genes.

Shape guides the growth of organoids
Shape guides the growth of organoids
Organoids are miniature lab-grown tissue structures that can mimic real organs. But guiding stem cells to grow an organoid of defined shape and size is difficult. Now, EPFL bioengineers have developed new methods for successfully guiding the stem cells to grow into intestinal tissues with real-life 3D structure and function.

Decoding inner language to treat speech disorders
Decoding inner language to treat speech disorders
A research team from the UNIGE and the HUG has succeeded in identifying certain signals produced by our brain when we speak to ourselves. What if it were possible to decode the internal language of individuals deprived of the ability to express themselves? This is the objective of a team of neuroscientists from the University of Geneva and the University Hospitals of Geneva (HUG).

Like our social media feeds, our brains take a little while to update
Time-lapse videos of faces morphing from young to old and male to female demonstrate how the brain lags when processing visual changes. (Image courtesy of Mauro Manassi) Like our social media feeds, our brains are constantly uploading rich, visual stimuli. But instead of seeing the latest image in real time, we actually see earlier versions because our brain's refresh time is about 15 seconds, according to new UC Berkeley research.

Gene-blocking could be key to curbing obesity
PhD candidate Brent Wakefield led a breakthrough study that could be crucial in addressing obesity. (Photo by Max Martin/Western Communications) It sounds too good to be true: blocking a gene linked to obesity to trigger a major reduction in body fat. While it's not a reality for humans yet, it could be one step closer thanks to new discoveries from a team of anatomy and cell biology researchers in a lab led by Silvia Penuela at Western's Schulich School of Medicine & Dentistry.
