Alzheimer's Tau protein forms toxic complexes with cell membranes
Alzheimer's disease is caused by tangles in the brain made up of malfunctioning aggregated Tau proteins. Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.

UZH Spearheads Largest European Study on Aging
UZH Spearheads Largest European Study on Aging
What began in 2012 is now entering its final stages: Europe's largest study on aging. The international research network behind the DO-HEALTH study is led by Heike Bischoff-Ferrari, Professor of Geriatric Medicine and Aging Research at the University of Zurich, and Head of the Department of Geriatrics at the UniversityHospital Zurich and the Waid City Hospital in Zurich, Switzerland.

Global Warming - New Study Calls for Decisive Action
Global Warming - New Study Calls for Decisive Action
The largest global study to date on the effects of climate change on temperature-related mortality shows that more deaths due to hot weather may not be balanced by fewer deaths in colder world regions should global temperatures continue to rise. Swiss TPH, working for improved health of the people around the globe, prepared the data set for Switzerland.

A milestone in the fight against malaria
A milestone in the fight against malaria
The malaria parasite employs an effective trick: it forces transmission from human to human as soon as the conditions in the host deteriorate. An international research team has discovered the molecule that plays a key role in this process. Malaria parasites are both dangerous and versatile. On entering the human bloodstream, they multiply exponentially.

Animals' mitochondria defenses discovered in plants
Animals' mitochondria defenses discovered in plants
Scientists at EPFL have discovered that the mechanism that mitochondria use to defend mammalian cells against protein-damaging stress also exists in plants. The work is published in Molecular Cell. Image: Arabidopsis thaliana plants used in this study. On the left is a plant under normal growth conditions, while on the right is a plant treated with doxycycline, which has significantly stunted its growth but is protected against aging as evidenced by its fresher appearance (credit: J. Auwerx/EPFL).

Virtual reality reduces phantom pain in paraplegics
Virtual reality reduces phantom body pain in paraplegics and creates the illusion that they can feel their paralyzed legs being touched again. The results could one day translate into therapies to reduce chronic pain in paraplegics. In breakthrough research led by neuroscientist Olaf Blanke and his team at EPFL, Switzerland, the scientists show that phantom body pain can be reduced in paraplegics by creating a bodily illusion with the help of virtual reality.

How
How "sleeper cells" in cancerous tumours can be destroyed
Media releases, information for representatives of the media Media Relations (E) In many metastasised types of cancer, disseminated tumours grow back despite successful chemotherapy. As a research team under the direction of the University of Bern has now discovered, this is because of isolated cancer cells that survive the chemotherapy due to a phase of dormancy.

How much does life weigh?
How much does life weigh?
ETH researchers have developed a scale for measuring cells. It allows the weight of individual living cells, and any changes in this weight, to be determined quickly and accurately for the first time. The invention has also aroused significant interest both in and outside the field of biology. From earthworms and sunflowers to human beings, we are all made up of cells, so it's no surprise that researchers are hard at work investigating these building blocks of life.

Possible new immune therapy target in lung cancer
Possible new immune therapy target in lung cancer
Media releases, information for representatives of the media Media Relations (E) A study from Bern University Hospital in collaboration with the University of Bern shows that so-called perivascular-like cells from lung tumors behave abnormally. They not only inadequately support vascular structures, but also may actively modulate the inflammatory and immune response.

The female brain reacts more strongly to prosocial behavior
The female brain reacts more strongly to prosocial behavior
Behavioral experiments have shown that when women share a sum of money more generously than men. To gain a more in-depth understanding of this behavior, neuroscientists from the Department of Economics looked at the areas of the brain that are active when decisions of this kind are made. They are the first to demonstrate that the brains of men and women respond differently to prosocial and selfish behavior.

Our muscles measure the time of day
Our muscles measure the time of day
Researchers funded by the SNSF have discovered a biological clock at work in our muscle cells. It could be a factor in regulating our metabolism and play a role in diabetes. Biological clocks are ticking everywhere throughout our body. They trigger the release of the hormone melatonin during sleep, favour the secretion of digestive enzymes at lunchtime or keep us awake at the busiest moments of the day.

Emerging infectious disease threatens Darwin's frog with extinction
Emerging infectious disease threatens Darwin’s frog with extinction
The Darwin's frog ( Rhinoderma darwinii ) is the latest amphibian species to face extinction due to the global chytridiomycosis pandemic, according to an international study published today in the journal Proceedings of the Royal Society of London B. The study has found that Darwin's frogs are infected with the fungal pathogen Batrachochytrium dendrobatidis ( Bd ), and despite an absence of obvious mortality researchers have noted population declines, leading them to believe that these infected populations are at a serious risk of extinction within 15 years of contracting the disease.

Tumor metabolism helps classify hepatoblastoma
Tumor metabolism helps classify hepatoblastoma
Looking at cell metabolism instead of histology, EPFL scientists have identified new biomarkers that could help more accurately classify the two main subtypes of hepatoblastoma, a liver cancer in children. Hepatoblastoma is a rare pediatric liver cancer, usually diagnosed in the first three years of life.

A new approach to high insulin levels
A new approach to high insulin levels
Congenital hyperinsulinism is a serious yet poorly understood condition. Research funded by the SNSF has discovered how it is caused by a genetic mutation. Diabetes is characterised by a deficiency of insulin. The opposite is the case in congenital hyperinsulinism: patients produce the hormone too frequently and in excessive quantities, even if they haven't eaten any carbohydrates.

Life Expectancy Increases in Switzerland
Life Expectancy Increases in Switzerland
Countries have saved more lives over the past decade according to the annual Global Burden of Diseases (GBD) study published yesterday. In Switzerland, life expectancy has increased to 85 years for women and to 81 years for men. The Swiss Tropical and Public Health Institute contributed to the GDB, the world's largest scientific collaboration on population health.

How Liver Cancer Develops
How Liver Cancer Develops
Liver cancer is the second-leading cause of cancer-related death and represents the fastest rising cancer worldwide. In most cases, the tumor develops in patients with chronic liver disease. Such diseases include chronic infections with hepatitis viruses or a so-called fatty liver due to nutritional or genetically caused lipometabolic disorders or an excessive consumption of alcohol.
