Daniel Krauze: “Luis Miguel is not a popular idol like Juan Gabriel was”

According to the criteria ofKnow moreWhen politicians speak in their novel, the topic they never address is precisely politics. As in "Pulp Fiction", where the hitmen do not talk about crimes but about hamburgers, the Mexican writer Daniel Krauze he writes a "thriller" so realistic that it seems implausible, where the level of corruption of congressmen and their political operators reaches levels that are difficult to believe. "Tenebra" (Seix Barral) deals with a year in the life of Julio Rangel, a guy to whom politics has given everything and in the life of Martín Ferrer, to whom the same policy decimated his grandfather's fortune and bankrupted his father. Both star in a story in which corruption operates in multiple ways and in which politics is the best pretext to talk about values ...

Russians, Sovereign 02 vaccine and sun and beach to reactivate Cuban tourism

The sun and the beach, and even more so the 23 kilometers of sandy beaches of Varadero, are once again the jewels of Cuban tourism in these times of pandemic. The covid-19 has left most of the foreign clients in their homes and about 85% of the Cuban hotels closed, but a year of forced rest has helped nature and the beaches to regenerate, while some of the most emblematic hotel facilities of the famous Cuban resort have been able to carry out major repairs. Years ago, when no one could foresee what was coming, the island had made a strong commitment to diversify tourism and promote the values ​​of its heritage cities. In addition to having hundreds of kilometers of pristine beaches and keys, Cuba is the country in the Caribbean area that has the most historical centers, fortresses and la...

The First Meteor Shower of The Year Is Starting! Here's How You Can See It

The first meteor shower of spring is peaking Thursday morning.The Lyrid meteor shower, which happens in late April each year, occurs when the Earth passes through the tail of a comet. As debris from that comet enters our planet's atmosphere, it burns up, leaving streaks in the sky that are visible to the naked eye for several seconds.  When the Lyrids peak, people can expect to see between 10 and 20 meteors every hour. These meteors often leave "glowing dust trains" in their wake as they disintegrate, according to NASA.The moon is more than half full this week, which will make it trickier to spot the shooting stars. Here are some tips for catching the Lyrids in action.Head out early Thursday morning, before the Sun risesThe best time to glimpse the Lyrids is in the wee morning hours on Th...

If Planet Nine Is Out There, It May Not Be Where We Think

If Planet Nine is out there, a large, mysterious planet lurking at the dark edges of the Solar System, it may not be where we thought it might be.According to astronomers searching for the hypothetical object, new information taken into account could mean that its orbit is significantly more elliptical than most recently predicted.  The hypothetical Planet Nine made a big entrance in 2016, when astronomers Konstantin Batygin and Michael Brown of Caltech published a paper in The Astronomical Journal. In it, they set out their case for an as-yet undiscovered planet in the outer reaches of the Solar System. The evidence, they said, lay in other objects from far beyond the orbit of Neptune.These objects are called Extreme Trans-Neptunian Objects (ETNOs). They have huge elliptical orbits, neve...

Newly Discovered Region of The Milky Way Is Filled With Stars Ready to Blow Up

Astrophysicists have found a new region of the Milky Way, and it's filled with searingly hot, bright-blue stars that are about to explode.The researchers were creating the most detailed map yet of the star-flecked spiral arms of our galactic neighborhood with the European Space Agency's (ESA) Gaia telescope when they discovered the region, which they have named the Cepheus spur, they reported in a new study.  Nestled between the Orion Arm – where our solar system is – and the constellation Perseus, the spur is a belt between two spiral arms filled with enormous stars three times the size of the sun and colored blue by their blistering heat.Astronomers call these giant, blue stars OB stars due to the predominantly blue wavelengths of light that they emit. They are the rarest, hottest, shor...

Sunnier Areas Have Lower COVID-19 Death Rates

So how might extra sunlight curb COVID-19? According to Weller's group, one possible explanation is that sun exposure causes the skin to release a chemical called nitric oxide. Some laboratory studies have found that nitric oxide may reduce the ability of the new coronavirus to replicate and spread. The study authors are planning to follow-up with more research regarding this theory. Previous research by the same team found that increased sunlight exposure is associated with better heart health, lower blood pressure and fewer heart attacks. Heart disease is a known risk factor in dying from COVID-19, so that past research could also help explain the new findings, they suggested. Two COVID-19 experts in the United States agreed that the findings were intriguing, b...

This Interstellar Object Could Be The First Truly Pristine Comet We've Ever Seen

In our limited experience, comet 2I/Borisov is one of a kind.It was discovered in August 2019, on a trajectory that could only mean one thing - the object had come from outside of our Solar System. It was the first known comet to visit from interstellar space, and represented a unique opportunity to study exocomet formation.  New analyses have now proven that 2I/Borisov is even more special than we thought. Based on a close examination of the comet's dust, scientists have determined that it's likely the most pristine comet we've ever seen.This suggests the comet has never been close to a star - the closest it's been was when it flew by our Sun in 2019 - which means it's essentially unchanged since it formed from the cloud of dust it was born in."2I/Borisov could represent the first truly ...
