The young plant's pantry does more than just feed it
The young plant’s pantry does more than just feed it
A team from the University of Geneva has observed that the role of plant tissue - called endosperm - is not only to feed the seed but is crucial for the development and protection of young plants. The endosperm, the tissue surrounding the plant embryo in the seed, has long been perceived as a nourishing tissue that is abandoned once the transition to the seedling is complete.

Fossil rivers of the Sahara tell of the threat of warming
Fossil rivers of the Sahara tell of the threat of warming
A UNIGE-led team has studied the fossil rivers of the Egyptian Sahara to reconstruct the region's rainfall rates that led to a major migration of people away from the Nile valley 10,000 years ago. Why did the people living near the Nile river migrate to central Egypt 10,000 years ago, when the Egyptian Sahara was still green? Geologists led by the University of Geneva , Switzerland, have studied the fossil rivers north of Lake Nasser in Egypt in order to reconstruct the palaeo-hydrology of the region and to determine the rainfall rate of this African humid period.

Fighting multiple sclerosis with cold
Fighting multiple sclerosis with cold
Scientists from the University of Geneva are demonstrating how cold could alleviate the symptoms of multiple sclerosis by depriving the immune system of its energy. In evolutionary biology, the "Life History Theory", first proposed in the 1950s, postulates that when the environment is favourable, the resources used by any organism are devoted for growth and reproduction.

The human immune system is an early riser
The human immune system is an early riser
Swiss and German scientists show that activation of the immune system oscillates throughout the day, with a peak just before the start of the day. Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms.

Did Venus, Earth's twin sister, ever have oceans?
Did Venus, Earth’s twin sister, ever have oceans?
Astrophysicists led by the UNIGE and the NCCR PlanetS have investigated the past of Venus to find out whether Earth's sister planet once had oceans. The planet Venus can be seen as the Earth's evil twin. At first sight, it is of comparable mass and size as our home planet, similarly consists mostly of rocky material, holds some water and has an atmosphere.

Mindfulness meditation helps preterm-born adolescents
Mindfulness meditation helps preterm-born adolescents
The practice of mindfulness shows a positive impact of the intervention on the adolescents' everyday life and on their ability to react to new events. Adolescents born prematurely present a high risk of developing executive, behavioural and socio-emotional difficulties. Now, researchers from Geneva University Hospitals (HUG) and the University of Geneva have revealed that practicing mindfulness may help improve these various skills.

A single gene can disrupt the sleep-wake cycle
A single gene can disrupt the sleep-wake cycle
A team from the University of Geneva has identified a gene that is essential for regulating the sleep-wake cycles of Drosophila. All living organisms are subject to an internal biological rhythm, which controls many physiological processes. In humans in particular, this internal clock follows a 24-hour cycle and occurs even in the absence of external triggers, such as changes in light or temperature.

Relieving pain by mapping its biological signatures
Relieving pain by mapping its biological signatures
Researchers at the University of Geneva and the Clinique romande de réadaptation in Sion have mapped the biomarkers of different types of pain to categorise and better treat them in the future. Many people are confronted with chronic pain that can last for months or even years. How to best treat chronic pain? First, pain must be categorized for the right treatment to be prescribed.

An algorithm to predict psychotic illnesses
An algorithm to predict psychotic illnesses
Teams from the UNIGE and EPFL have used for the first time the method of longitudinal network analysis applied to children, in order to detect the symptoms that herald the development of psychotic illness in the future. One third of children with a microdeletion of chromosome 22 will later develop a psychotic illness such as schizophrenia.

The defensive arsenal of plant roots
The defensive arsenal of plant roots
A team from the University of Geneva has discovered the mechanisms that regulate the formation of the protective layer of plant roots. Plants adapt to their nutritional needs by modifying the permeability of their roots through the production or degradation of a cork-like layer called suberin. By studying the regulation of this protective layer in Arabidopsis thaliana , an international team, led by scientists from the University of Geneva , Switzerland, has discovered four molecular factors responsible for the genetic activation of suberin.

How tactile vibrations create illusions
How tactile vibrations create illusions
Researchers from the University of Geneva and UNIFR decipher how the amplitude and frequency of tactile vibrations can bias how the brain interprets them. Among the traditional five human senses, touch is perhaps the least studied. Yet, it is solicited everywhere, all the time, and even more so in recent years with the widespread daily use of electronic devices that emit vibrations.

Very old Universe reveals new galaxies
Very old Universe reveals new galaxies
Scientists serendipitously discover two heavily dust-enshrouded galaxies that formed when the Universe was only 5% of its present age. While investigating the data of young, distant galaxies observed with the Atacama Large Millimeter/submillimeter Array, Yoshinobu Fudamoto from Waseda University and the National Astronomical Observatory of Japan noticed unexpected emissions coming from seemingly empty regions in space that, a global research team confirmed, came actually from two hitherto undiscovered galaxies heavily obscured by cosmic dust.

How serotonin curbs cocaine addiction
How serotonin curbs cocaine addiction
By identifying the role of serotonin during cocaine use, scientists explain why only one in five persons becomes addicted to this drug. Contrary to common thinking, cocaine triggers an addiction only in 20% of the consumers. But what happens in their brains when they lose control of their consumption? Thanks to a recent experimental method, neuroscientists at the University of Geneva , Switzerland, have revealed a brain mechanism specific to cocaine, which has the particularity of triggering a massive increase in serotonin in addition to the increase in dopamine common to all drugs.

Surprise: the Milky Way is not homogeneous
Astronomers from the UNIGE have observed the composition of the gases in our galaxy and have shown that, contrary to the models established until now, they are not homogeneously mixed. In order to better understand the history and evolution of the Milky Way, astronomers are studying the composition of the gases and metals that make up an important part of our galaxy.

How to produce proteins at the right speed
How to produce proteins at the right speed
Using a dynamic observation technique of protein synthesis, scientists from the University of Geneva have deciphered the genetic mechanisms governing the speed of translation of messenger RNA. In all eukaryotic organisms, genetic material is stored in the cell nucleus in the form of DNA. In order to be used, this DNA is first transcribed into messenger RNA in the cell cytoplasm, then translated into protein with the help of ribosomes, small machines capable of decoding messenger RNA to synthesise the appropriate proteins.

Maternal voice reduces pain in premature babies
Maternal voice reduces pain in premature babies
A team from the University of Geneva shows that the maternal voice reduces signs of pain in premature babies when they undergo life-saving medical interventions. A baby born prematurely often has to be separated from its parents and placed in an incubator in intensive care. For several weeks, he or she will undergo routine medical procedures that can be painful, without being relieved by too many pharmaceutical painkillers, which are risky for his or her development.

Cancer: information theory to fight resistance to treatments
Cancer: information theory to fight resistance to treatments
Researchers from the UNIGE and the HUG have used information theory for the first time to monitor in vivo the development of resistance mechanisms to a cancer-targeted therapy. One of the major challenges in modern cancer therapy is the adaptive response of cancer cells to targeted therapies: initially, these therapies are very often effective, then adaptive resistance occurs, allowing the tumor cells to proliferate again.
