2022-08-27 02:31:01 Genetic engineering experts have produced a "synthetic" mouse embryo without using egg or sperm cells.

The embryos produced using stem cells were able to start developing a heart, brain, and other organs for up to a week.

2022-08-26 23:59:06 In the coming years, multiple space agencies will send astronauts to the Moon. In NASA's case, this will consist of the Artemis Program sending astronauts (the "first woman and first person of color") to the Moon for the first time since the Apollo Era. For the European Space Agency (ESA), the Russian State Space Corporation (Roscosmos), the China National Space Agency (CNSA), and possibly the India Space Research Organization (ISRO), this will consist of sending astronauts, cosmonauts, taikonauts, and gaganauts to the Moon for the first time.

2022-08-26 21:30:52 A team of scientists is hurrying along the coastline, salvaging coastal homes, habitats, and what is left of a navigable harbor — all with striking green sand in hand. While we hate to tell you that this obscure material has nothing to do with kryptonite, it sure does have a unique, eliminating power. This green sand is a highly reactive form of the crushed-up volcanic mineral known as olivine. And it can capture carbon dioxide.

2022-08-26 04:30:58 Photographer Felix Steele has developed a 3D-printed 164mm f/2.5 lens that has no fasteners or screws. And it’s cheaper than regular lenses.

He managed to design a lens which is less than $15 using affordable glass. Steele also named his first major project “Pixels and Prisms.”

2022-08-26 02:30:17 A sunspot that was a blip a few days ago has now grown ten times its original size and is comparable to the size of a planet now. Solar scientists are following its activity to see what happens next since the sunspot is aimed directly at the Earth.

Sunspots are regions on the surface of the Sun that have strong magnetic fields which temporarily halt the process of convection in the area. As a result, the region's temperature drops considerably, making it appear darker when observed from the Earth.

Sometimes sunspots end up as eruptions that release intense bursts of energy or even magnetically charged particles from the Sun, which can head straight toward the Earth. These outbursts are called solar flares and are responsible for weather in space, just like the weather on Earth.

2022-08-25 23:55:06 Researchers have harnessed mechanical information processing and integrated it into an engineered material that can "think."

Scientists built on research dating back to 1938, and harnessed mechanical information processing, and integrated it into an advanced form of material.

"We have created the first example of an engineering material that can simultaneously sense, think and act upon mechanical stress, without requiring additional circuits to process such signals," said Ryan Harne, an associate professor of mechanical engineering.

2022-08-25 21:31:00 Snow cones are a type of shaved ice that is served in paper cups or plastic cones. This type of food is most commonly found at carnivals and fairs, but it has become more common for people to buy snow cone machines for home use.

The snow cone machines are priced differently depending on the quality and features offered. The cheapest ones are priced at around $35, but they can go up to $500 if you want to buy a commercial machine with a lot of features. That being said, we will focus on the ones that are built specifically for home use.
