This week’s new scientists have seen us look deep into the cosmos and the depths of our oceans.
To understand the universe today, we have to look back on its first era, about 13 billion years ago known as Cosmic Dawn. Until now, space telescopes have been our only way to go up so far, but this week, astronomers have detected traces of light left by the first stars Use of a ground telescope – A scientific farm previously thought impossible.
From deep space to the deep ocean, researchers discovered more secrets on “The richest sinking in the world“Off the Colombian coast, while other scientists have captured a Red Blood Handica Cammar On the camera for the first time.
Meanwhile, while the researchers spotted remarkable things underwater, something that should normally live there was recently presented In a very unexpected place.
Incredible discoveries
From cleaning cell debris to the regulation of blood flow, brain cells in the shape of a star called astrocytes are crucial to keep your brain healthy, but a new study shows that they could also play a key role in the way the brain stores memories.
While neurons were once considered as the only architects of thought and brain memory, scientists used automatic learning to understand how astrocytes behave when neurons interact with each other to form connections.
They found that astrocytes help store memories thanks to changes in calcium -based signals that they send inside and between cells, and in turn, these calcium signaling models are sent to neurons and regiment their activity.

Latest research
Earthquakes are notoriously difficult to predict, but a recent study suggests that California’s faults are late for certain earthquakes. By studying the interval between earthquakes on defects in five regions subject to the earthquake with a long geological file, the geoscientists have developed which were “late” for an earthquake.
While the faults of most of these regions were less than 20% late, which increased to around 45% in the case of the Golden State.

Beyond the headlines
Bariatric surgery is an extremely effective weight loss treatment, but in addition to reducing people’s body weights, the procedure is often linked to mental health improvements. A new study suggests that these improvements may not depend on the amount of weight lost, but rather patients with less weight stigmatization after surgery.
The “weight stigmatization” refers to the attitudes, bias and negative beliefs that people have about overweight or obesity; Some of these biases arise from the false idea that controlling your weight is only a question of will. Among the patients included in the new study, most said they had undergone less stigmatization after bariatric surgery, as well as better physical and mental health. A smaller subset of patients continued to undergo stigma after their procedures and was then more at risk of poor mental health and diet.
The study fills a “gap” in our understanding of the factors that can affect the results of patients after these surgeries, which are more and more common.

Science in pictures
This week, we were treated to a part of the sun That no one has ever thrown eyes before – the South -Solar Pole. Plunging at an angle of 17 degrees under the solar equator, the European Space AgencyThe solar orbits (ESA) captured images of the southern pole of the star using a large strip of visible and ultraviolet wavelengths, giving life to the tangled canvas of the magnetic field and the chemical elements of the sun while they travel on huge plasma breakdowns.
These new images will allow scientists to better understand the solar wind, space time and the cycle of the changing magnetic field of the sun.
“Today, we reveal the first views of humanity on the post of the sun”, ” Carole MundellDirector of Sciences of ESA, said in a press release. “These new unique views of our Solar Orbiter mission are the beginning of a new era of solar science.”
