In Italy, a Labrador gives birth to … a green puppy

The phenomenon is rare but natural. While waiting to see the color fade, the puppy was named « Pistachio ».

A n original birth to say the least. On October 9, two farmers from Sardinia in Italy discover their female Labrador in full labor. One, two, three She ends up giving birth to five puppies. But surprise, one of them is … green!

« It looked like an extraterrestrial Italian). dog », tell the two men to the local newspaper Nuova Sardegna

Precedents

Intrigued, the two farmers do research and discover that this phenomenon does exist. It is caused by biliverdin, a green substance in bile that can mix with amniotic fluid during childbirth. It’s rare, but natural and not isolated.

There were also some precedents. In 2012, a little green Labrador was born in England, just like in Spain in 2014. The color should fade over time. Until then, « Pistache » is doing wonderfully.

Are O blood groups less at risk for Covid-19 disease?

Evidence is beginning to add in favor of the blood group variable in the risk of infection with the coronavirus SARS-CoV-2, and the severity of the disease.null

The severity of the coronavirus sometimes varies greatly from person to person. Several factors may come into play, although not all have yet been fully identified. People over 60 are generally the most at risk, as their health profile is more fragile. More surprisingly, more and more studies point to the differences in severity between men and women, especially for chromosomal reasons .

Evidence is also starting to accumulate strongly in favor of variable severity depending on blood type, but also an equally variable susceptibility to infection: on October 14, 2020, two studies were simultaneously published in Blood Advances .

A’s and AB’s more at risk than O’s and B’s

People with blood group O seem less likely to be infected with the coronavirus and have a severe version of the disease. // Source: Pixabay

For the first study , the authors observed a sample of about 100 patients between February and April 2020. Those of type O and B spent an average of 4.5 days less in intensive care. Only 61% of patients in groups O and B were placed on ventilation, when 84% of patients in groups A (AB) and B were concerned. In addition, the latter also had a greater need for dialysis, to help the kidneys evacuate toxins present in the blood. “  Covid-19 patients with group A or AB appear to be at greater risk for severity when patients with group O or B,  ” the researchers write.

The second study , for its part, does not look at the severity but at the susceptibility to infection, that is to say the risks that the coronavirus develops in the body by infecting it. “  O blood groups are associated with a lower risk of acquiring SARS-CoV-2 infection  ,” the authors conclude.

They retrospectively analyzed nearly 500,000 patient profiles in the Netherlands, comparing the distribution of blood groups among these coronavirus-positive people with a control group of 2 million people in the population. This is how they were able to determine that, compared to the prevalence of O in the control population, their prevalence was lower in O, whereas it remained consistent for the other blood groups.

These results carry weight mainly because they agree with a body of other results with similar conclusions.  »  Patients with blood group B or AB who were tested were more likely to test positive, and those with blood group O were less likely to test positive,   » reports a study published in July 2020 . Another, conducted in June and published on October 15, reaffirms the lower risk of serious symptoms in O. However, this research can be influenced by the distribution of blood groups within the population studied. But the influence of blood groups in the risk of infection is not that much of a surprise for this coronavirus, since the subject had already been discussed for SARS-CoV-1 15 years ago, which still supports a little more the potential role of this variable.

Voici les 4 plus belles photos d’animaux de l’année

Les prix de la 56e édition du Wildlife Photographer Of The Year, le plus prestigieux concours de photographie de nature au monde, seront annoncés ce mercredi.

Les résultats de la 56e édition du Wildlife Photographer Of The Year, le plus prestigieux concours de photographie de nature au monde, seront annoncés ce mercredi matin. Voici en avant-première le lauréat et nos trois coups de cœur.

Sensuelle tigresse

Du pur plaisir. Cette tigresse qui frotte sa joue contre l’écorce d’un sapin de Mandchourie est désormais une star. Sa photo, titrée « l’Etreinte » que nous vous présentons en exclusivité, est la grande gagnante, du 56e prix Wildlife, organisé par le Natural History Museum de Londres. Le cliché, signé du Russe Sergey Gorshkov, est le fruit d’une sacrée dose de patience, comme souvent dans l’art de la photo animalière. Sergey Groshkov a installé un piège photo en janvier 2019 face à ce grand sapin. Après avoir écumé la forêt pour y dénicher des traces, il espérait qu’un tigre de Sibérie s’y colle pour y laisser le marquage de ses glandes odorantes. Problème, dans le parc national du Léopard, dans l’extrême-est de la Russie, les proies sont rares et les territoires de chasse immenses pour les quelque 500 à 600 félins qui y vivent. Ce n’est donc pas avant le mois de novembre suivant qu’il a pu réaliser le portrait de cette étreinte magnifique en pleine nature.

Les guêpes normandes

«Le Conte des deux guêpes» (à gauche : la guêpe ammophile des sables, à droite, la guêpe coucou). /Frank Deschandol/Wildlife Photographer of the Year 2020 

Rien à voir avec la tigresse de Sibérie qui dégage tant de puissance. Le Français Frank Deschandol, lauréat dans la catégorie « Comportement : invertébrés » a, lui, capturé plein cadre des spécimens bien plus petits, deux espèces différentes de guêpes. Une guêpe coucou et une ammophile des sables. Cette dernière pond des œufs qu’elle ravitaille en chenilles tandis que la première, en véritable parasite, n’a qu’une idée en tête : s’incruster dans son terrier pour y pondre à son tour. Ses propres larves ont alors un festin tout trouvé avec la progéniture de l’ammophile. C’est près de sa maison en Normandie, dans une friche industrielle, que Frank Deschandol a repéré ses deux modèles alors qu’elles étaient sur le chemin de leur nid… commun pour le plus grand malheur de l’ammophile.

«Show business». /Kirsten Luce/Wildlife Photographer of the Year 2020

 Alors que toutes les photos sélectionnées nous plongent en pleine nature, celle-ci se pose d’emblée comme une intruse. Un ours polaire au pelage blanc immaculé fait le beau face à une dresseuse en costume de patineuse. La main levée, elle lui fait faire un numéro. Pour prévenir tout danger, l’animal sauvage a la gueule muselée par du grillage. Une image « choquante », peut-on lire dans le commentaire du Wildlife. Primée dans la catégorie « photojournaliste de nature », elle est réalisée par l’Américaine Kirsten Luce dans un cirque russe qui s’est arrêté à Kazan, dans le Tartarstan (Russie). On apprend qu’il s’agit en fait d’une ourse sauvage capturée à l’âge de 2 ans, toujours au travail 18 ans plus tard quand ce cliché a été pris. La photo fait écho à l’actualité française alors que le gouvernement vient d’annoncer la fin de l’exploitation des animaux sauvages dans les cirques ambulants.

Un nez, un cap, une péninsule

«Méditation»./Mogens Trolle/Wildlife Photographer of the Year 2020

 Mogens Tolle photographie les primates depuis cinq ans. Ce Danois est récompensé pour son portrait incroyable de nasique réalisé à Bornéo. Les paupières – bleues — closes, le jeune mâle à la fourrure auburn semble en pleine méditation, indifférent à son long nez. Cet appendice, qui aurait fait passer Cyrano de Bergerac pour un petit joueur, est sa marque de fabrique. Et quoi de mieux qu’une pose de profil pour le mettre en valeur ? Pourquoi est-il si long et le deviendra d’ailleurs encore plus en vieillissant au point de pendouiller ? L’appendice sert notamment d’ampli quand son propriétaire crie, ce qui est loin d’être son cas au moment du déclenchement. Les nasiques sont si paisibles, voire apathiques qu’ils sont facilement chassés. L’espèce est donc menacée, comme beaucoup de celles qui sont immortalisées par les photographes du Wildlife.

La tigresse et les 99 autres plus belles photos présentées cette année au concours sont à retrouver dans le livre « Wildlife Photographer of the year », disponible dès ce mercredi (Ed. Biotope, 34 euros)

The 4 most beautiful animal photos of the year

The prizes for the 56th edition of Wildlife Photographer Of The Year, the world’s most prestigious nature photography competition, will be announced on Wednesday.

“The Embrace” is the grand winner of the 56th Wildlife Prize, organized by the Natural History Museum in London. Sergey Gorshkov / Wildlife Photographer of the Year 2020

The results of the  56th edition of Wildlife  Photographer Of The Year, the world’s most prestigious nature photography competition, will be announced this Wednesday morning. Here is a preview of the winner and our three favorites.

Sensual tigress

Pure pleasure. This tigress who rubs her cheek against the bark of a Manchurian fir is now a star. Her photo, titled “The Embrace” which we present to you exclusively, is the big winner of the 56th Wildlife Prize, organized by the Natural History Museum in London. The photo, signed by Russian Sergey Gorshkov, is the result of a sacred dose of patience, as is often the case in the art of animal photography. Sergey Groshkov set up a photo trap in January 2019 in front of this large tree. After scouring the forest to find traces, he hoped that a Siberian tiger would stick there to leave the markings of its scent glands. Problem, in the Leopard National Park, in the far east of Russia, prey is scarce and the hunting grounds huge for the approximately 500 to 600 felines that live there.

Norman wasps

Nothing to do with the Siberian tigress who gives off so much power. Frenchman Frank Deschandol, winner in the “Behavior: invertebrates” category, has captured much smaller specimens in full frame, two different species of wasps. A cuckoo wasp and a sand amphibian. The latter lays eggs which it supplies with caterpillars while the first, a real parasite, has only one idea in mind: to become embedded in its burrow to lay there in turn. Its own larvae then have a feast all found with the offspring of the marram grass. It was near his house in Normandy, in an industrial wasteland, that Frank Deschandol spotted his two models while they were on the way to their common … nest, to the great misfortune of the marram grass.

Find the mistake

« Show business ». / Kirsten Luce / Wildlife Photographer of the Year 2020

 While all the selected photos immerse us in nature, it immediately arises as an intruder. A polar bear with an immaculate white coat looks good in front of a trainer in a skater costume. With her hand raised, she makes him dial a number. To prevent any danger, the wild animal has its mouth muzzled by wire netting. A « shocking » image, can we read in the commentary of Wildlife. Awarded in the category « photojournalist of nature », it is carried out by the American Kirsten Luce in a Russian circus which stopped in Kazan, in Tartarstan (Russia). We learn that it is in fact a wild bear captured at the age of 2, still at work 18 years later when this picture was taken. The photo echoes French news as the government just announced the end of the exploitation of wild animals in traveling circuses .

A nose, a cape, a peninsula

“Meditation” ./ Mogens Trolle / Wildlife Photographer of the Year 2020

 Mogens Tolle has been photographing primates for five years. This Dane is rewarded for his incredible portrait of nasic made in Borneo. The eyelids – blue – closed, the young male with auburn fur seems in full meditation, indifferent to his long nose. This appendix, which would have made Cyrano de Bergerac pass for a small player, is his trademark. And what better than a profile pose to highlight it? Why is it so long and will it become even longer as it ages to the point of dangling? The appendix serves in particular as an amplifier when its owner cries, which is far from being the case when it is triggered. Nasics are so peaceful, even apathetic, that they are easily shunned. The species is therefore threatened, like many of those which are immortalized by wildlife photographers.

The tigress and the 99 other most beautiful photos presented this year at the competition can be found in the book « Wildlife Photographer of the year », available this Wednesday (Ed. Biotope, 34 euros)

Coronavirus: Cristiano Ronaldo positive for Covid-19

Cristiano Ronaldo, the captain of Portugal, opposed this Wednesday (8:45 p.m.) to Sweden as part of the League of Nations, has tested positive for Covid-19. The Juventus striker is asymptomatic.

The Portuguese Federation explained this Tuesday afternoon why the training planned for the morning was delayed (it must start at 6 p.m.): Cristiano Ronaldo, the captain of the Seleçao, has tested positive for Covid-19 but he is asymptomatic. All the other players in the selection are negative.

He left the gathering and was placed in quarantine. Recall that the Turinese had left Italy last week,  without the agreement of the Italian health authorities,  to join the national team. The European champions had already seen, before meeting the Blues  last Sunday (0-0),  José Fonte (Lille) then  Anthony Lopes  (Lyon) leave the city of football due to positive tests.

Portugal is opposed to Sweden  this Wednesday (8:45 p.m.)  in Lisbon as part of the League of Nations.

Coronavirus : Cristiano Ronaldo positif au Covid-19

Cristiano Ronaldo, le capitaine du Portugal, opposé ce mercredi (20h45) à la Suède dans le cadre de la Ligue des nations, a été testé positif au Covid-19. L’attaquant de la Juventus est asymptomatique.

La Fédération portugaise a expliqué ce mardi après-midi pourquoi l’entraînement prévu dans la matinée a été retardé (il doit débuter à 18 heures) : Cristiano Ronaldo, le capitaine de la Seleçao, a été testé positif au Covid-19 mais il est asymptomatique. Tous les autres joueurs de la sélection sont, eux, négatifs.

Il a quitté le rassemblement et été placé en quarantaine. Rappelons que le Turinois avait quitté l’Italie, la semaine dernière, sans l’accord des autorités sanitaires italiennes, pour rejoindre l’équipe nationale. Les champions d’Europe avaient déjà vu, avant de rencontrer les Bleus dimanche dernier (0-0), José Fonte (Lille) puis Anthony Lopes (Lyon) quitter la cité du football en raison de tests positifs.

The difference between a sea and an ocean

It is very difficult to tell the difference, whether we are talking about sea or ocean, the two are characterized as a vast expanse of salt water that covers part of the surface of the globe. To differentiate them, three criteria serve as a reference: extent, depth and location.

Big oceans

The oceans are very large expanses of salt water bordered by continents, for Europeans it is this that Christopher Columbus crossed. Until the discovery of the « great ocean » that Magellan traveled. He found it very calm and therefore called it « Pacific Ocean ». If we classify them by their importance in terms of volume and surface area, we can distinguish the Pacific, Atlantic, Antarctic, Indian and Arctic oceans. The amplitude of the tides is generally very important there.

And smaller seas

The seas, for their part, are less vast and generally shallower. They are always found inside a continent, while the ocean surrounds a continent. There are three types of seas:

1. Seas that are closed to the interior of the mainland like the Caspian Sea and the Dead Sea look like large salt lakes.

The Caspian Sea, an example of a closed sea within a continent

2. Seas which communicate by strait with an ocean or another sea such as the Mediterranean Sea with the Atlantic Ocean and the Black Sea with the Mediterranean Sea.

The Mediterranean Sea is connected by the Strait of Gibraltar with the Atlantic Ocean

3.The seas open to an ocean or a sea having a larger extent such as the Sargasso Sea

La différence entre une mer et un océan

Il est bien difficile de faire la différence ,que l’on parle de mer ou d’océan, les deux se caractérisent comme une vaste étendue d’eau salée qui couvre une partie de la surface du globe. Pour les différencier, trois critères servent de référence : l’étendue, la profondeur et la localisation.

De grands océans

Les océans sont de très grandes étendues d’eau salée bordées par les continents, pour les Européens c’est elle que Christophe Colomb a traversée. Jusqu’à la découverte du  « grand océan » que Magellan a parcouru. Il le trouva bien calme et le dénomma donc « océan Pacifique ». Si on les classe par leur importance en matière de volume et de superficie on distingue les océans Pacifique, Atlantique, Antarctique, Indien et Arctique. L’amplitude des marées y est en général très importante.

Et des mers plus petites

Les mers, sont quant à elles moins vastes et généralement moins profondes. Elles se trouvent toujour à l’intérieur d’un continent, tandis que l’océan lui, entoure un continent. Il existe trois types de mers :

1.Les mers qui sont fermées à l’intérieur du continent comme la mer Caspienne et la mer Morte ressemblent à de grands lacs salés.

La mer caspienne,exemple d’une mer fermée à l’intérieur d’un continent

2.Les mers qui communiquent par détroit avec un océan ou une autre mer comme la mer Méditerranée avec l’océan Atlantique et la mer Noire avec la mer Méditerranée.

La mer Méditerranée est reliée par le détroit de Gibraltar avec l’océan Atlantique

3.Les mers ouvertes sur un océan ou une mer ayant une étendue plus importante comme la mer des Sargasses

New York – London in 3h30? The return of a commercial supersonic aircraft takes shape

With a maximum speed of Mach 2.2, the supersonic aircraft XB-1 will offer a flight time between New York and London of 3h30 instead of 7, a Los Angeles Sydney in 6:45 instead of 15 …

 This prototype should pass the sound barrier by the end of next year
This prototype should pass the sound barrier by the end of next year  Boom Supersonic

Fifty-one year after the Concorde’s first flight and 17 years after its commercial shutdown due to the takeoff crash of an Air France aircraft, supersonic commercial planes could make their return to the sky.

Boom Supersonic presented a first demonstrator of its XB-1 whose objective is to take off by the end of next year.

This start-up, which has received the support of Google, Airbnb or Dropbox, has so far registered around thirty pre-orders at $ 200 million each from the Virgin Group and Japan Airlines.

65 to 88 passengers

Its objective: to offer by 2030, an aircraft with a capacity of 65 to 88 “economically viable” passengers that can fly at a maximum speed of Mach 2.2. The flight time between New York and London will then be 3:30 instead of 7, that between Los Angeles and Sydney will be 6:45 instead of 15 …

For the development of this aircraft of the future, Boom Supersonic will start by flying a demonstrator which corresponds to a third of the size of the final aircraft.

Boom Supersonic
Boom Supersonic

This 21-meter-long and 6-meter-wide prototype will only accommodate the pilot. Equipped with three Rolls Royce engines, it will start by undergoing its first flight tests by the end of next year with the aim of breaking the sound barrier .
