This week, the land has witnessed an amazing show not seen since 2022 – a total lunar eclipse. This celestial hide and seek game treated the sky observers treated at the spectacular view of our neighbor, becoming a beautiful shade of red, in what is commonly called a “blood moon”.
This unusual coloring occurs during a total lunar eclipse due to a phenomenon called Rayleigh diffusion, which means that certain light wavelengths disperse more than others. During a total lunar eclipse, the earth perfectly blocks the rays of the sun, but the light folds around the edge of our planet, through the atmosphere. There, the particles in the atmosphere disperse the blue light of shorter wavelength, leaving the lengths of orange and red wave wave to cover the moon in their distinctive shade.
If you have missed the breathtaking view, you may have another chance of seeing a total lunar eclipse this year, from September 7 to 8. However, the best views will be in Asia, with North America largely intact. Until then, take advantage of these adorable Blood Moon photos of this weekor try our moon quiz To see how much you know our lunar neighbor.
A “pregnant” mummy with “cancer”
In 2021, the researchers saw a mummy of the first century-BC which had been discovered in the Egyptian city of Luxor (Ancient Thebes) and moved to the University of Warsaw in 1826. The team of experts concluded that, unlike the previous belief, the mummy was not a male priest but a woman in her twenties. Not only that, but she was 6.5 to 7.5 months pregnant and knew potentially deadly nasopharyngeal cancer in her skull – at least they thought.
At the time, other experts did not agree on what radiographs and computed tomography revealed in the abdomen of the mummy, nicknamed the “mysterious lady”. Instead, they suggested that it contained embalming packs. From now on, an analysis of more than 1,300 gross computed tomography of the mummy added additional support to this view.
The researchers behind the new study revealed that the object that the previous research team thought was a “marinated” fetus was in fact part of the embalming process and that there was no clear evidence of cancer in the mummy. Instead, skull damage probably came when the brain was removed during the embalming process, in which an curved metal implement was used to Pull the brain through the nostrils.

Pi Day
Originally defined as the ratio between the circumference of a circle and its diameter, pi – Written as the Greek letter π – appears throughout mathematics, including in fields completely not connected to circles, such as chemistry, physical sciences and medicine.
Pi belongs to a huge mathematical group called irrational numbers, which continue forever and cannot be written as fractions. Scientists calculated Pi at 105 billions of figures, although most of us know more approximation 3.14. But How do we know that Pi is an irrational number?

How does metformin work
Metformin, a drug used to treat type 2 diabetes, has been prescribed by doctors since the 1990s. Despite its effectiveness, there has been a persistent puzzle: how does it work?
Now, a new study brings us closer to a little more understanding of the key mechanism in the way metformin lowers blood sugar. The drug triggers the body to expel glucose from blood circulation and in the intestines. There, bacteria feed on carbohydrates to make compounds that help control blood sugar.
Keeping glucose out of traffic by leading it to the intestine could directly reduce blood sugar levels, but scientists have said to science live that they thought it explains Only one of the therapeutic effects of metformin.

Launch of spherex
This week, Nasa launched the spherex telescope in orbit. The new infrared space telescope is set to compete James Webb space telescope In his unprecedented vision of our universe.
Once Spherex is entirely online, the space telescope will scan the night sky four times, using 102 infrared color sensors, allowing it to collect data from more than 450 million galaxies during its planned two -year mission. This data set will give scientists a key overview of some of the biggest questions in cosmology, such as the way galaxies take shape and evolve over time, where water is born and how our universe has become.
