Embryos taking shape via buckling
Embryos taking shape via buckling
Scientists have demonstrated that cellular tissues are deformed by buckling (or bending under the action of compression), a phenomenon that could lie behind embryo morphogenesis. The embryo of an animal first looks like a hollow sphere. Invaginations then appear at different stages of development, which will give rise to the body's structures (the brain, digestive tract, etc.).

Mechanism discovered how the coronavirus hijacks the cell
Mechanism discovered how the coronavirus hijacks the cell
Researchers at ETH Zurich and the University of Bern have discovered a mechanism by which the corona virus manipulates human cells to ensure its own replication. This knowledge will help to develop drugs and vaccines against the corona virus. Like a pirate hijacking a ship, a virus takes control of an infected cell because every virus depends on the resources and molecular machines of the cell to multiply.

Machine-learning helps sort out massive materials' databases
EPFL and MIT scientists have used machine-learning to organize the chemical diversity found in the ever-growing databases for the popular metal-organic framework materials. Metal-organic frameworks (MOFs) are a class of materials that contain nano-sized pores. These pores give MOFs record-breaking internal surface areas, which can measure up to 7,800 m2 in a single gram of material.

Transistor-integrated cooling for a more powerful chip
Transistor-integrated cooling for a more powerful chip
Researchers have created a single chip that combines a transistor and micro-fluidic cooling system. Managing the heat generated in electronics is a huge problem, especially with the constant push to reduce the size and pack as many transistors as possible in the same chip. The whole problem is how to manage such high heat fluxes efficiently.

Amphipods: a miraculous increase in biodiversity
Amphipods: a miraculous increase in biodiversity
Until recently, researchers assumed that Switzerland had around 20 native species of amphipods. Now, a project by the Swiss Federal Institute of Aquatic Science and Technology (Eawag) and the University of Zurich has revealed that there are actually more than 40. It is always worth taking a closer look, because we can only protect the things that we know exist.

Restless nature of human spinal cord, non-invasive imaging reveals
Scientists have developed a non-invasive technique for unraveling the complex dynamics generated by spinal cord circuits to unprecedented detail, a first in functional magnetic resonance imaging that may one day help diagnose spinal cord dysfunction or injury. The spinal cord roughly looks like a long tube, with a diameter of only 1.5 cm, and yet this crucial part of the nervous system is essential for controlling how our arms and legs move, for giving us our sense of touch as well as a notion of where our bodies are in space.

Brain stimulation reduces dyslexia deficits
Brain stimulation reduces dyslexia deficits
Reading difficulties can be improved with non-invasive brain electrical stimulation, a hope for people suffering from dyslexia. Dyslexia is a frequent disorder of reading acquisition that affects up to 10% of the population, and is characterised by lifelong difficulties with written material. Although several possible causes have been proposed for dyslexia, the predominant one is a phonological deficit, a difficulty in processing language sounds.
