More people die as a result of lung cancer each year than from breast, colorectal and prostate cancer combined.1 While in recent years there...
Growing hand with HoxD combinatorial code. The image below is an overlay of the large-scale hand sculpture with Hox genes combinatorial code distribution along a diffusion map, illustrating genetic diversity in the growing limb. Each dot being one cell, the colors represent the single-cell combinatorial Hoxd code that match with different degree of differentiation, a recent concept also described as pseudo-temporal ordering of single-cells. The graphic highlights the switch between cellular temporal states involved in a regulatory network. The cells with only one gene are in a more premature state while the one expressing a higher set of these genes being at the end of their maturation.

Revenge is a form of establishing justice and that the threat of revenge may serve as a form of protection, a kind of enforcement...
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...
