COVID-19: a respiratory vaccine effective in mice
Less known to the general public, mucosal vaccination via the mucus membranes could provide robust protection against SARS-CoV-2 infections. Immune cells in the nose and lungs are considered better prepared to encounter and block the virus that causes COVID-19. An international research team has just demonstrated that its mucosal DNA vaccine is capable of ensuring the total survival of a group of mice infected with a version of the virus adapted to this species, whereas the latter kills 100% of unvaccinated mice 1 .

Fatty liver disease endangers brain health
Fatty liver disease endangers brain health
People with liver disease caused by eating too much sugar and fat could be at increased risk of developing serious neurological conditions like depression or dementia. In a study examining the link between non-alcoholic fatty liver disease (NAFLD) and brain dysfunction, scientists at the Roger Williams Institute of Hepatology, affiliated to King's College London and the University of Lausanne, found an accumulation of fat in the liver causes a decrease in oxygen to the brain and inflammation to brain tissue - both of which have been proven to lead to the onset of severe brain diseases.

How can flying insects and drones tell up from down?
How can flying insects and drones tell up from down?
A team of European researchers has established a new principle that explains how flying insects determine the direction of gravity, without using accelerometers. These results are an important step towards the creation of tiny autonomous drones. For proper operation, drones usually use accelerometers to determine the direction of gravity.

How can digital data stored as DNA be manipulated?
Data can be encoded as DNA but are difficult to process thereafter. A new method enables operations to be performed on DNA-encoded data directly, without having to first translate them into their electronic equivalent. DNA can be used to reliably store a vast amount of digital data. However, retrieval or manipulation of specific data encoded in these molecules has hitherto been difficult.

Sahelanthropus, the oldest representative of humanity, was indeed bipedal...but that’s not all!
The modalities and date of emergence of bipedalism remain bitterly debated, in particular because of a small number of very old human fossils. Sahelanthropus tchadensis , discovered in 2001 in Chad, is considered to be the oldest representative of the humankind. The shape of its cranium suggests a bipedal station.
