Artist's view of a sunset over KELT-9b. The nearby warm blue star covers 35° in the planet's sky, about 70 times the apparent size of the sun in the Earth's sky. Under this scorching sun, the planet's atmosphere is warm enough to shine in reddish-orange tones and vaporize heavy metals such as iron and titanium

Scientists detected iron and titanium in the atmosphere of a ultra hot exoplanet

For the first time, scientists at the University of Geneva in collaboration with the University of Bern (UNIBE), Switzerland, have discovered the presence of iron...
When a metal ion is inserted, the molecule changes geometry, acting as an on/off switch. (UNIGE)

New chemical sensor detects metals in the environment

Scientists at the University of Geneva (UNIGE), Switzerland have developed a new molecular switch that is capable of binding metals present in its environment. The...

When the seed becomes plant, it has 48 hours to survive

Germination is the process of seeds developing into new plants. First, environmental conditions must trigger the seed to grow. Usually, this is determined by...
One drop of blood is enough for TBIcheck to diagnose a possible mild brain trauma. If a line appears below the control line, the injured person will have to go to the hospital for a CT scan. © UNIGE

New portable device capable of diagnosing mild traumatic brain injury within 10 minutes

In today's date, CT Scan is the only reliable method to detect traumatic brain injury and suggests diagnosis accordingly. But the facility is available...

A new method to detect planet within few months

To find and affirm the presence of a planet around stars other than the Sun, stargazers hold up until the point when it has...

Nano and micro join forces to treat osteoarthritis

There is at present no treatment for restoring osteoarthritis, which influences 80% of the populace more than 75 years old. The main plausibility is...
The planet becomes visible when looking for H2O or CO molecules. However, as there is no CH4 nor NH3 in its atmosphere, it remains invisble when looking for these molecules, just as its host star which contains none of those four elements.© UNIGE

Hunting molecules to find new planets

Each exoplanet rotates around a star, similar to the Earth around the Sun. This is the reason it is for the most part difficult...
Immune cells that ingested spider silk nanoparticles (in green). The endosomes - the part of the cell in which the nanoparticles release the vaccine - appear in blue. (Illustration © Laboratoire Bourquin – UNIGE.)

Scientists developed a new vaccine based on spider silk microcapsules

Scientists from the universities of Geneva (UNIGE), Freiburg (UNIFR), Munich, and Bayreuth, in collaboration with the German company AMSilk, have developed spider silk microcapsules...
The helix structure of BACOVO: the oxygen atoms, represented in red, are organized in octahedra around the cobalt atoms, located at their center. The blue arrows represent the small moments carried by the cobalt atoms, ordered antiferromagnetically along the helical chain. © CEA/CNRS/UGA

The apparent inner calm of quantum materials

Researchers from the University of Geneva (UNIGE), the CEA, CNRS, and UGA in collaboration with scientists from the neutronic centers ILL and PSI have...
