How to turn a tentacle into a foot
How to turn a tentacle into a foot
By identifying a key regulator of cell identity, a team from the University of Geneva and the FMI has succeeded in modifying the structure and function of tentacle cells in hydra. Humans, animals, plants: all multicellular organisms are made up of specialized cells called differentiated cells. Thus, the cells that make up the epidermis do not have the same identity - nor the same function - as those that line the digestive system, for example.

Fighting cancer is more efficient at dawn
Fighting cancer is more efficient at dawn
Scientists from the UNIGE and LMU show that the anti-tumour activity of the immune system - and the effectiveness of cancer immunotherapies - depends on the time of day. The ability of tumours to take hold and grow depends, among other things, on the effectiveness of the immune system in fighting them.

Covid-19: the Spike protein is no longer the only target
Covid-19: the Spike protein is no longer the only target
A research team reveals a hidden cavity on a key SARS-CoV-2 protein to which drugs could bind. With the continuous emergence of new variants and the risk of new strains of the virus, the development of innovative therapies against SARS-CoV-2 remains a major public health challenge. Currently, the proteins that are on the surface of the virus and/or are involved in its replication are the preferred therapeutic targets, like the Spike protein targeted by vaccines.

James Webb reveals the atmospheric secrets of an exoplanet
Thanks to the James Webb Space Telescope, an international team including scientists is building a complete picture of the atmosphere of the planet WASP-39b. The James Webb Space Telescope (JWST) and its unparalleled images of our Universe offer us a new first: by combining several instruments, it draws a molecular and chemical portrait of the atmosphere of the exoplanet WASP-39b.

A new nanoparticle to act at the heart of cells
A new nanoparticle to act at the heart of cells
A team from the University of Geneva and LMU developed a transport nanoparticle to make an anti-inflammatory drug much more effective and less toxic. How can a drug be delivered exactly where it is needed, while limiting the risk of side effects? The use of nanoparticles to encapsulate a drug to protect it and the body until it reaches its point of action is being increasingly studied.

Summer camps promote altruism in children
Summer camps promote altruism in children
A team from the University of Geneva shows that participating in camps helps develop valuable socio-emotional skills. Be able to control oneself, cooperate or help others: having socio-emotional abilities is essential for those who wish to interact positively with their peers. These skills are largely acquired during childhood and can be trained in different contexts, such as school, family or leisure.

A new weapon against antibiotic-resistant bacteria
A new weapon against antibiotic-resistant bacteria
A team from the University of Geneva reveals that a drug used against herpes can fight a bacterium that is resistant to most antibiotics by weakening its defence mechanisms. The unreasonable use of antibiotics has pushed bacteria to develop resistance mechanisms to this type of treatment. This phenomenon, known as antibiotic resistance, is now considered by the WHO as one of the greatest threats to health.

Gamma Columbae: the story of a cosmic striptease
Gamma Columbae: the story of a cosmic striptease
A research team supported by the SNSF and including scientists from the UNIGE has studied the particular properties of the star Gamma Columbae. It is believed to be a binary star whose core has been exposed. A bright star visible to the naked eye, but until recently a star that was of no particular interest to scientists.

Detecting the antibodies responsible for thromboses and miscarriages
A team from the HUG, the UNIGE and Endotelix has developed a new test to detect antiphospholipids. This new test could detect antiphospholipid syndrome (APS), which causes clots that lead to thrombosis and disrupts pregnancy. Endotelix The Geneva University Hospitals (HUG), the University of Geneva and their spin-off Endotelix have created the best possible target molecule for the antibodies responsible for antiphospholipid syndrome.

The major chord that cures nightmares
The major chord that cures nightmares
A team from the UNIGE and the HUG has developed a promising method for treating people whose negative dreams are pathological. Oppressive, frightening, nerve-wracking: nightmares are particularly disturbing dreams. They are considered pathological when they occur frequently (>1 episode per week) and cause daytime fatigue, mood alteration and anxiety.

A key regulator of cell growth deciphered
A key regulator of cell growth deciphered
A team from the University of Geneva has identified the structure of a protein complex controlling the activity of the major regulator of cell growth. The mTOR protein plays a central role in cell growth, proliferation and survival. Its activity varies according to the availability of nutrients and some growth factors, including hormones.

A revolutionary method to observe cell transport
A revolutionary method to observe cell transport
A team from the University of Geneva, in collaboration with the UZH, has developed an innovative strategy for studying membrane proteins, the targets of many drugs. Membrane proteins are key targets for many drugs. They are located between the outside and inside of our cells. Some of them, called ''transporters'', move certain substances in and out of the cellular environment.

Espresso detects barium in the atmosphere of an exoplanet
Espresso detects barium in the atmosphere of an exoplanet
The spectrograph developed by the UNIGE has enabled the discovery of the heaviest element ever detected in the atmosphere of a planet outside the solar system. An international team including researchers from the University of Geneva and the National Centre of Competence in Research (NCCR) PlanetS has detected the heaviest element ever found in the atmosphere of an exoplanet: barium.

Non-native species are also beneficial to the ecosystem
A team of scientists makes the case for reevaluating maligned non-native species. Awareness of non-native species - often called ''invasive'' - has vastly increased over the past fifty years, to the point where anyone with green conscience has heard of them and their negative effects, whether it is the zebra mussel or ragweed.

Zinc could treat a rare genetic disorder
Zinc could treat a rare genetic disorder
By deciphering mutations in the GNAO1 gene, which cause severe mental and motor disabilities, a team from the University of Geneva is showing how zinc could improve the brain defects at stake. Paediatric encephalopathies of genetic origin cause severe motor and intellectual disabilities from birth. One of these diseases, first identified in 2013, is caused by mutations in the GNAO1 gene.

Diabetes: when circadian lipid rhythms go wrong
Diabetes: when circadian lipid rhythms go wrong
A team from Geneva, Switzerland, shows that the disruption of lipid temporal profiles in type 2 diabetes stiffens the membrane of pancreatic endocrine cells, which could alter their function. Like all living beings, human physiological processes are influenced by circadian rhythms. The disruption of our internal clocks due to an increasingly unbalanced lifestyle is directly linked to the explosion in cases of type 2 diabetes.

Awakening 'dormant' cells to fight cancer
Awakening ’dormant’ cells to fight cancer
A team from the UNIGE and the HUG has succeeded in identifying a drug-targetable mechanism whose blockage reduces the capacity of melanoma cells to adapt and resist to treatment. The advent of small-molecule targeted therapies, a decade ago, revolutionized the treatment of metastatic melanoma, provided that the tumors carry the mutations to respond to these treatments.
