Facilitating diagnosis with a new type of biosensor
Scientists from the Max Planck Institute and EPFL have developed a new type of biosensor able to precisely quantify metabolites using a single drop of blood. The accuracy and simplicity of the procedure could make it a tool of choice for diagnosing and monitoring several diseases. Diseases or injuries can result in dramatic changes in the blood levels of metabolites, which are chemical compounds produced by the body's metabolism.

B Cells Among Factors Leading to Brain Lesions in Multiple Sclerosis
B Cells Among Factors Leading to Brain Lesions in Multiple Sclerosis
A team of researchers has shown that in multiple sclerosis, it is not only specific T cells that cause inflammation and lesions in the brain. B cells, a different type of immune cell, also play a role. These cells activate T cells in the blood. This discovery explains how new MS drugs take effect, opening up novel options for treating the disease.

Like a zipper - How cells form new blood vessels
Like a zipper - How cells form new blood vessels
Blood vessel formation relies on the ability of vascular cells to move while remaining firmly connected to each other. This enables the vessels to grow and sprout without leaking any blood. In the current issue of ‘Nature Communications', scientists from the Biozentrum at the University of Basel describe how this works.

Eating less is healthy thanks to gut bacteria
Eating less is healthy thanks to gut bacteria
Mice with a lower calorie intake live longer and are both healthier and leaner. A team of researchers may have found the reason for this positive effect: much of it is down to gut microbial communities and how they affect the immune system. The researchers also found compounds that mimic caloric restriction and may transform obesity treatments.

Regenerating nerve fibers across spinal cord injury
Regenerating nerve fibers across spinal cord injury
Scientists have designed a three-stepped recipe for regenerating electro-physiologically active nerve fibers across complete spinal cord lesions in rodents. Rehabilitation is still required to make these new nerve fibers functional for walking. The results appear in today's issue of Nature. The adult mammalian body has an incredible ability to heal itself in response to injury.

How the forest copes with the summer heat
How the forest copes with the summer heat
Between April and August this year, Switzerland and central Europe have experienced the driest summer season since 1864. Especially the forest seems to suffer from this dry spell: As early as August, trees began to turn brown this year. A current study by the University of Basel indicates now that native forest trees can cope much better with the drought than previously expected.

Protein Modifications that Point to Cancer
Protein Modifications that Point to Cancer
Researchers from the University of Zurich can, for the first time, precisely characterize the protein modification ADP-ribosylation for all proteins in a tissue sample. The changes, which are a typical reaction to stress, provide information about the condition of a cell. Together with the University Hospital Zurich, they are now testing the new method to diagnose and treat cancer.

Cichlids: watching speciation in real time
Cichlids: watching speciation in real time
Cichlids belong to one of the largest fish families, with new species emerging all the time. These colourful, shimmering fish evolve so fast that Eawag researchers have now been able to practically observe them in the process of their evolution. Within the space of several thousand years, one cichlid can evolve into hundreds of different species.

Increased phosphate intake elevates blood pressure in healthy adults
Increased phosphate intake elevates blood pressure in healthy adults
If more phosphate is consumed with food, blood pressure and pulse rate increase in healthy young adults. These findings were shown by a study led by the University of Basel and published in the Journal of the American Society of Nephrology. They make processed cheese spreadable, prevent coffee from clumping and help preserve many meat products: phosphates are a common additive in industrially produced foodstuffs.

Dominant men make decisions faster
Dominant men make decisions faster
Men who exhibit high social dominance make faster decisions than low-dominance men even outside a social context, finds a large behavioral study from EPFL. Hierarchies exist across all human and animal societies, organized by what behavioral scientists refer to as dominance. Dominant individuals tend to climb higher up the hierarchy ladder of their particular society, earning priority access to resources.

How an herbivore hijacks a nutrient uptake strategy of its host plant
How an herbivore hijacks a nutrient uptake strategy of its host plant
The struggle for iron determines the fate of maize and insect pest: Maize plants release secondary metabolites into the soil that bind to iron and thereby facilitate its uptake by the plant. The Western corn rootworm, the economically most important maize pest worldwide, is attracted by these complexes, extracts the bound iron from the maize plant and uses it for its own nutrition.

Amputees feel as though their prosthetic limb belongs to their body
In a breakthrough approach that combines virtual reality and artificial tactile sensations, two amputees feel as though their prosthetic hand belongs to their own body. Moreover, the scientists show that the phantom limb actually grows into the prosthetic hand. The famous idiom "seeing is believing" is not enough to help amputees with the use of their prosthetic limb.

Differences in immune responses due to age, sex, and genetics
Differences in immune responses due to age, sex, and genetics
Age, sex, and specific human genetic variants are the key factors behind differences between immune responses among healthy humans, finds a study of 1,000 individuals carried out by EPFL and the Pasteur Institute. Over the course of our life, we are continuously exposed to pathogens such as viruses and bacteria, meaning that our immune system is constantly at work.
