COVID-19: in uncommon times, dark matter specialists have applied their skills to ventilators
COVID-19: in uncommon times, dark matter specialists have applied their skills to ventilators
The Mechanical Ventilator Milano (MVM), an open source ventilator to support patients severely ill with COVID-19, has moved from design to reality in six weeks, propelled by physicists specialised in dark matter who turned their attention away from unknown particles for this period. It has just been authorised by the US Food and Drug Administration (FDA) as within the scope of the emergency use authorization for ventilators in intensive care.

Systematic mapping of cell wall mechanics in the regulation of cell morphogenesis
Abstract: Walled cells of plants, fungi, and bacteria come with a large range of shapes and sizes, which are ultimately dictated by the mechanics of their cell wall. This stiff and thin polymeric layer encases the plasma membrane and protects the cells mechanically by opposing large turgor pressure derived mechanical stresses.

Modulation of tissue growth heterogeneity by responses to mechanical stress
Publication from the Laboratoire Reproduction et développement des plantes (RDP) in the journal Proceedings of the National Academy of Sciences USA (PNAS) on January 23, 2019. Abstract:  Morphogenesis often yields organs with robust size and shapes, whereas cell growth and deformation feature significant spatiotemporal variability.

A model for describing the hydrodynamics of crowds
By studying the movement of runners at the start of marathons, researchers from the Laboratoire de physique (CNRS/ENS de Lyon/UCBL) have just shown that the collective movements of these crowds can be described as liquid flows. Their results, published in Science on January 4, 2019, have enabled them to predict how fluctuations in speed and density are transmitted through massive crowds.

Fish in schools can take it easy
Fish in schools can take it easy
Using a new computer model, researchers at the Ecole Centrale de Marseille and CNRS have shown that a fish expends less energy when it swims in a school, because neighbouring fish produce a 'suction' effect. This work will be published on 11 May 2018 in Physical Review Letters . Schools of fish provide a fascinating example of collective behaviour in which the group moves in a coordinated manner without the need for a leader.

Dyslexia : when spelling problems impair writing acquisition
Dyslexia : when spelling problems impair writing acquisition
Dyslexia is a learning difficulty which affects the ability to adopt the automatic reflexes needed to read and write. Several studies have sought to identify the source of the problems encountered by individuals with dyslexia when they read. Little attention, however, has been paid to the mechanisms involved in writing.

Light-controlled gearbox for nanomachines
Rewarded with a Nobel Prize in Chemistry in 2016, nanomachines provide mechanical work on the smallest of scales.

A Mechanical Feedback Restricts Sepal Growth and Shape in Arabidopsis
A Mechanical Feedback Restricts Sepal Growth and Shape in Arabidopsis
A research team of the Laboratory of Plant Reproduction and Developmen t (RDP - Inra, ENS de Lyon, CNRS, Université Claude Bernard Lyon 1), has just revealed that organs sense their own growth and can therefore control their final shape.
