As we know from Experience with Covid-19Tracing the source of the epidemic is very difficult.

More than two years since the virus emerged in China, we still don’t know how it passed to humans or which animal or animal hosted the virus before this pivotal event.

Humans have lived with microbes since our earliest days, but now we are.”They live in the era of epidemicssaid epidemiologist Dr. Larry Brilliant, CEO of Pandefense Advisory, a network of experts involved in responding to the pandemic. But thanks to DNA analysis, the scientific investigation work needed to understand these pathogens has come a long way, as evidenced by one of this week’s exciting discoveries.

This is Katie Hunt, standing for Ashley Strickland, in this version of Wonderland Theory.

Pictured is a tombstone from a grave site in Kyrgyzstan, where the outbreak of the plague that caused the Black Death likely originated.

The Black Plague was the most devastating plague outbreak in the world. can be Half of Europe’s population was killed in just seven years during the Middle Ages.

Historians and archaeologists for centuries have tried to determine the source of this epidemic, and now science has developed and provided an answer.

Traces of the diseases that sickened our ancestors – including the plague – can be found hidden in ancient DNA from human remains.

The genome sequence of the Yersinia pestis bacteria found in teeth excavated from two cemeteries in what is now Kyrgyzstan, He may have solved the mystery From the mysterious origins of the Black Death.

The life of a mastodon, an elephant creature that roamed across North America 13,000 years ago, has been shed by the study of its tusks.

For the first few years of his life, he was a boy to a mother – he stayed close to home with a female-led herd in what is now central Indiana before venturing out on his own. mastodons He died at the age of 34, when the tip of the tusk of another mastodon man punctured the right side of Skull.

creature Canines store geochemical information that shrubs and trees absorb and water consumable, enabling scientists for the first time to work together where the animal I travelled over his life.

This is an artist's impression of a black hole drifting through our Milky Way.

We now have the most complete map yet of the Milky Way, our home galaxy, and it shows us some pretty cool stuff.

Some stars in the Milky Way have Strange and unexpected ‘tsunami-like’ stellar earthquakesNew data from the European Space Agency’s Gaia space telescope has revealed. The movement even changed the shape of some stars.

Hubble, another space telescope that surveys the sky, has discovered an equally interesting cosmic phenomenon.

The invisible ghostly remnants of a radioactive star drift into the Milky Way. It’s the first time A wandering black hole has been discovered Although astronomers believe there may be 100 million of these floating objects.

The division of male and female dominant animals It is among nature’s most enduring gender stereotypes. A new book, “Bitch: Into the Female Species,” debunks this sexist misconception and tells a more complete story about the role of females in the wild.

Female creatures are as mixed, competitive, aggressive, and dynamic as their male counterparts and play an equal role in driving evolutionary change, according to author Lucy Cook.

Details of her work details of a group’s life Some of the colorful animals that will change your assumptions about what it means to be female: killer meerkats, treacherous bluebirds, and female dolphins that have unusual strategy In the battle of the sexes.

polar bears Thinning and reducing the number of cubs Scientists say, as a result of the melting of sea ice in their Arctic habitat, But a new discovery may offer a glimmer of hope.

a Found a special group of polar bears live in the fjords in southeast Greenland Offers How can this species be able to survive With the intensification of the climate crisis.

Unlike most polar bears, which hunt seals on sea ice and roam far away, this distinct group has adapted to live in a smaller habitat and hunt on icy freshwater ice.

“If you are interested in preserving the species, then yes, our results are hopeful” said Kristin Lieder, a polar research scientist at the University of Washington’s Applied Physics Laboratory. “But I don’t think The glacier habitat will support huge numbers of polar bears. There is not enough of it.”

Marvel at these stories:
