10 good news and beautiful scientific discoveries of summer 2022

Even though the autumn equinox will only happen on the 23rd, the month of September is always associated with back to school, and… at the end of summer. On this occasion, a look back at the news that will have marked the months of June, July and August 2022, with an optimistic approach. James-Webb Space Telescope, Cancer Vaccine, Wild Tiger Population: Here are 10 Reasons to Trust Science … and the Future.

The James-Webb Space Telescope transmits its first images and prepares to revolutionize astronomy

The “telescope of the century” lived up to its title. On the evening of July 11, NASA unveiled the first images captured by the James-Webb Space Telescope. Galaxies, clusters of galaxies, nebulae, exoplanets … An incredible cosmic spectacle!

Beyond the fascination these images offer, they will enable spectacular advances in nearly all areas of astronomy. “In the team, we no longer know who to turn to. We spend hours zooming in on the image, observing the details. Just looking at it, I have ten research projects in mind“, Explains moved Hakim Atek, researcher at the Institute of Astrophysics in Paris and member of the team“ Origin and evolution of galaxies ”.

A cancer RNA vaccine with very encouraging results

In addition to the success against Covid-19, RNA vaccines represent immense hope in the fight against cancer. An American team managed to develop one, with excellent results on mice with metastatic melanoma.

Tumors were significantly inhibited, and 40% of mice showed complete remission, with no tumors and no long-term relapses when additional existing treatment was given. It remains, before declaring victory, to replicate these good results in man.

The bioartificial cornea restores sight to blind patients

In a pilot study, a team from the University of Linköping (Sweden) developed implants, from pig cells, to restore sight to people in need of a cornea transplant. Of the twenty patients recruited for this study, all with advanced keratoconus, 14 had gone blind and all had restored vision. Three of them even regained 20/20 sight.

Our results show that it is possible to develop a biomaterial that meets all clinical criteria, can be mass-produced, stored for up to two years and thus reach even more people with vision problems.“said Neil Lagali, professor of experimental ophthalmology at Linköping University.

An Anatolian leopard reappears, a species thought to be extinct

Fifty years since we had lost track! An Anatolian leopard has been officially identified in Turkey. “The Anatolian leopard, an important species that was last seen in our country in 1974 and thought to be extinct, has been spotted“, announced Vahit Kirişçi, Minister of Agriculture and Forests. The minister specifies that the Anatolian leopard could be observed thanks to a photo trap installed in 2019 in the middle of nature.

An exceptional Gallo-Roman sanctuary discovered near Rennes

In La Chapelle-des-Fougeretz, about twenty minutes from the center of Rennes, archaeologists have unearthed an important Gallo-Roman sanctuary founded in the 1st century BC Two temples, an esplanade, several houses and a vast building have been discovered thermal.

It is a valuable testimony because we have no written sources on this period.“explains Bastien Simier, a field archaeologist specializing in the Breton countryside in Inrap.”This type of large public sanctuary is not uncommon in Roman Gaul, but these remains are never excavated in their entirety.

The number of wild tigers in the world continues to increase

Wild tigers are 40% more numerous in the world than previously thought and the population of panther tigersseems to stabilize or even increase“, according to the International Union for Conservation of Nature.

The new count estimated the number of tigers in the wild to be between 3,726 and 5,578. A jump of 40% that “explained by improvements in tracking techniques, showing that there are more tigers than previously thoughtLocally, conservation plans for the species have also paid off, so much so that Nepal has nearly tripled its wild tiger population in 12 years.

The world’s first fleet of hydrogen trains enters service

It’s a world first! In Germany, a fleet of fourteen hydrogen trains replaced diesel locomotives on a railway line not far from Hamburg. A privileged track to reduce CO2 emissions, and replace diesel which still provides 20% of trips to Germany.

By 2035, around 15-20% of the European regional market could run on hydrogen“, Confirms to AFP Alexandre Charpentier, Roland Berger’s railway expert.

The gray wolf continues its progression in France

With a population estimated at 921 at the end of winter 2021-2022 by the French Bureau for Biodiversity and a revised upward figure for the previous year, wolves are even more numerous in France.

The wolf, who returned to France alone from Italy, experienced favorable demographic dynamics for 10 years, with “a satisfactory survival rate of the species and an increase in reproduction“, According to a press release from the prefect of the Auvergne-Rhône-Alpes region.

An AI predicted the structure of (almost) all known proteins

In just one year, the AlphaFold AI, developed by DeepMind, predicted the structure of 200 million proteins. They were collected and made available to the scientific community in the AlphaFold protein prediction database.

Fighting plastic pollution, understanding the origins of life or studying diseases … According to DeepMind, their model has already been used in more than 4,000 concrete research projects.

After reintroduction, iguanas breed naturally in the Galapagos

They had disappeared from the island of Santiago, in the Galápagos, more than a century ago. In 2019, the Galapagos National Park Authority (PNG) reintroduced more than 3,000 iguanas of the species Conolophus subcristatus on this island in order to restore their natural ecosystem.

A program that is paying off: the director of the PNG announced that “we again see a healthy population of land iguanas with adults, young and young. This is a great conservation achievement and strengthens our hopes for reintroduction.“.
