The James Webb telescope has detected the largest supermassive active distance black hole discovered to date inside the galaxy CEERS 1019. The description of the galaxy is available by The Astrophysical Journal Letters, in an article which provides information on two other black holes as well as eleven galaxies that were formed during the time […]

HiRISE, a high-resolution camera operated by the University of Arizona that works on NASA’s Mars Reconnaissance Orbiter (MRO) mission, has taken this picture of Mars’ red planet. It is reminiscent of the face of the bear. The orbital photo, which was taken on December 12, 2022, actually depicts the hill as the shape of a […]

A few days ago, we shared with you a non-exhaustive list of ten dinosaur discoveries that marked 2022. Now let’s move on to the other fossils unearthed or analyzed this year which are just as important from a scientific point of view. The oldest fossilized brain The Chengjiang Fossil Site in China preserves a series […]

Bipedalism is a defining characteristic of human lineage. It has long been believed that our ancestors began to walk on two legs in the more open environments of the African savannah. A recent study centered on chimpanzees, our closest cousins, nevertheless suggests that bipedalism may have first appeared in trees. The Savannah Hypothesis Mandatory terrestrial […]

Just as rovers rely on wheels to navigate lunar or Martian surfaces, some probes also use wheels (in this case, reaction wheels) to orient themselves in space without using thrusters. Engineers and technicians at NASA’s Jet Propulsion Laboratory recently installed four of these wheels on Europa Clipper which is being prepared for its journey through […]

In France, an association recently conducted a survey whose conclusion is quite worrying. 78% of bottled water tested during the study contained plastic microparticles. However, the level of microplastics in bottles differs between brands. A test on water marketed in France In 2018, we mentioned a study conducted by the Orb Media collective in the […]

We have long known that certain insects, such as bees, help plants reproduce by spreading their pollen from plant to plant. However, biologists have recently identified a surprisingly similar process in the underwater world, involving red algae and tiny crustaceans. This is the first known case of an animal helping algae reproduce. This new discovery […]

This minimally invasive wireless technology could be used in the future to restore vision in blind patients. Neuroengineers managed to activate and deactivate neurons and neural circuits of the fruit fly (Drosophila melanogaster) remotely and non-invasively and, for subseconds, controlled its flight. The new technology uses magnetogenetics, nanoparticles, electromagnets and is 50 times faster, in […]

A study takes stock of how the uptake of carbon by phytoplankton should evolve over the century according to different scenarios of global warming. If the conclusions agree on an increase in absorption between now and 2100, they diverge very widely beyond this horizon. The results were published in the journal PNAS on July 11. […]

Arid soils are protected from wind erosion by a “biocrust” whose role is to limit the amount of dust present in the atmosphere. However, this same biocrust faces a major threat: global warming. Over the next fifty years, the amount of dust in the atmosphere is expected to increase far from negligible and the effects […]
