Scientists Create Mice With Cells From 2 Males For 1st Time

Scientists have produced baby mice from two guys for the first time.

Although specialists caution that only a few mice embryos matured into live mouse pups, and no one knows whether it will work for humans, this raises the remote potential of employing the same approach on people.

But even so, “It’s a pretty creative method,” said Diana Laird, a stem cell and reproductive person at the University of California, who was not involved in the study. It’s a crucial phase in both reproductive biology and stem cell research.

Researchers revealed their work in a paper published in the journal Nature on Wednesday.

First, they created “induced pluripotent stem cells” from skin cells removed from the tails of male mice. These cells can differentiate into a variety of different cell or tissue types. They then developed functioning egg cells by converting male mouse stem cells into female cells by expanding them and administering medication. The embryos were then placed into female mice after being fertilized. 7 of the 630 embryos, or around 1%, developed into living mouse pups.

Last week, scientists at the Third International Conference on Human Genome Editing heard from research leader Katsuhiko Hayashi of Kyushu University and Osaka University in Japan that the pups appeared to develop properly and could become parents on their own in a typical way.

Laird and her colleague Jonathan Bayerl wrote a commentary that was published alongside the Nature publication in which they stated that the work “opens up new pathways in reproductive biology and mice fertility research” for both people and animals. In the future, it is feasible to procreate endangered mammals from a single male.

Unclear why so few embryos implanted into surrogate mice survived.

They said it “could even give a pattern for enabling more people to produce biological children while avoiding the ethical and legal concerns of donor eggs,” such as male same-sex couples.

However, they issued multiple warnings. Which is the most notable? The method could be more effective. They claimed it was unclear why so few embryos implanted into surrogate mice survived; there may be technical or biological reasons for this. However, they emphasized that it is still too early to determine whether the approach would even function with human stem cells.

Before employing stem cells to create eggs, Laird added that researchers must consider the mutations and mistakes that might be made in a culture dish.

The most recent study explores novel approaches to in vitro mouse embryogenesis. This summer, researchers in Israel and California developed “synthetic” mouse embryos from stem cells that lacked a mother’s ovum or egg.  Up to 8 12 days after conception, those mice embryos had the same characteristics as typical mouse embryos, including one that resembled a beating heart. The achievement, according to scientists, could one day serve as a model for producing artificial human embryos for future research.

CAPE CANAVERAL, Florida – The Webb Space Telescope discovered the earliest known merger of black holes. These two massive holes and their galaxies formed only 740 million years after the universe-creating Big Bang. Scientists claimed Thursday that they have made the furthest distant detection of merging holes ever.

Webb Telescope Uncovers Merger Of Two Massive Black Holes From Early Universe

A black hole is 50 million times bigger than our sun. The other is estimated to be similar in size but buried in dense gas, making it difficult to measure.

Until today, astronomers didn’t know how supermassive black holes got so huge.

The current findings, published in the Monthly Notices of the Royal Astronomical Society, imply that mergers explain how holes can expand quickly — “even at cosmic dawn,” according to lead author Hannah Ubler of the University of Cambridge.

“Massive holes have been shaping the evolution of galaxies from the very beginning,” Ubler stated.

Strong Solar Storm Could Disrupt Communications And Produce Northern Lights In US

Published

CAPE Florida’s Cape Coral — This weekend, a very powerful solar storm approaching Earth may cause communications outages and cause the northern lights to appear in the United States.

For the first time in almost 20 years, the National Oceanic and Atmospheric Administration issued a rare geomagnetic storm watch. The entire weekend is under scrutiny, beginning on Friday.

Strong Solar Storm Could Disrupt Communications And Produce Northern Lights In US

According to NOAA, the sun started to create powerful solar flares on Wednesday, which led to five plasma explosions that might have disrupted Earth’s power infrastructures and satellites in orbit. A coronal mass ejection, or eruption, can produce billions of tons of solar plasma.

The flares appear to be connected to a sunspot that is 16 times the diameter of Earth, which is why NOAA is classifying this as an uncommon occurrence. In 2003, a strong geomagnetic storm destroyed power transformers in South Africa and knocked out power in Sweden.

According to NOAA, the most recent storm may cause northern lights as far south as Alabama and Northern California in the United States.

An amazing natural occurrence is the aurora borealis, sometimes known as the northern lights. The night sky in Earth’s polar regions is home to these vibrant, dancing lights. When charged solar particles clash with atmospheric gasses, these lights are created.

Though the lights are usually observed in green, pink, and violet hues, they can occasionally be seen in other colors as well. Countless people travel to locations like Alaska, Canada, and Scandinavia every year to see this amazing show in person since it is such a stunning sight.

China Launches Long March-5 to the “Dark Side of Moon”

China has launched an unmanned spacecraft on a nearly two-month journey to gather rocks and soil from the moon’s far side, becoming the first country to undertake such an ambitious task.

China’s heaviest rocket, the Long March-5, lifted off at 5:27 p.m. Beijing time (0927 GMT) from the Wenchang Space Launch Center on the southern island of Hainan, carrying the Chang’e-6 probe weighing more than 8 metric tons.

China’s Chang’e-6 is entrusted with landing in the South Pole-Aitken Basin on the moon’s far side, which is continuously facing away from Earth, and retrieving and returning samples.

The launch is another significant milestone in China’s lunar and space exploration mission.

“It is a bit of a mystery to us how China has been able to develop such an ambitious and successful programme in such a short time,” said Pierre-Yves Meslin, a French researcher working on one of the Chang’e-6 mission’s scientific objectives.

In 2018, Chang’e-4 made China’s first unmanned moon landing on the far side. Chang’e-5 returned lunar samples for the first time in 44 years in 2020, and Chang’e-6 has the potential to make China the first country to retrieve samples from the moon’s “hidden” side.

Scientists, diplomats, and space agency officials from France, Italy, Pakistan, and the European Space Agency all attended the launch, which carried moon-study payloads on Chang’e-6.

However, no US groups requested for a payload place, according to Ge Ping, deputy director of the China National Space Administration’s (CNSA) Lunar Exploration and Space Program.

U.S. law prohibits China from collaborating with the United States’ space agency, NASA.

The Dark Side of the Moon

The far side of the moon, also known as the “dark side of the moon” despite receiving sunlight, is the hemisphere that always faces away from Earth. The Soviet Luna 3 spacecraft made the first observation of this strange region in 1959.

Unlike the near side, the far side lacks enormous, dark basins known as marias. Instead, hundreds of craters produced by asteroid collisions over billions of years blanket it.

The South Pole-Aitken Basin, an immense crater more than 1,500 miles wide and several miles deep, is one of the most visible landforms on the far side. This ancient impact basin is among the largest known crater formations in our solar system. The far side likewise has many mountains, ridges, and other harsh topography formed by cosmic collisions.

Studying the far side provides insights into the moon’s genesis and early history because it maintains impact records from the solar system’s turbulent childhood.

Scientists also intend to investigate it for potential resources and future lunar bases. With no atmosphere or magnetic field, the far side displays the wounds of endless meteor bombardments, exposing information about Earth’s only natural satellite that the near side lacks.
