No, these are not pictures of caramel corn—they’re the new close-ups of the sun, taken by the largest solar telescope ever built, and they’re what the Internet has been abuzz about for a week. The Daniel K. Inouye Solar Telescope (DKIST) is able to capture imagery three times more detailed than anything we’ve seen before. What we’re looking at here in this video are huge bubbling cells as big as Texas, transferring heat from the sun’s interior to its surface, but the telescope can also resolve tiny features as small as Manhattan Island within the cells!

The DKIST is about 13 feet wide and has a better-than-bird’s-eye-view at 10,000 feet above sea-level on the summit of Haleakala, a massive shield volcano on Hawaii’s island Maui. The area covered in this image is about 22,600 miles by 22,600 miles, but the cell-like structures shown are about the size of Texas.

This is only the first time it’s been used so far, and scientists are hoping that in the future it will be helpful in predicting solar weather. Scientists still have a lot of questions about the dynamical processes in the sun and space weather is a focus that can have significant impact on the everyday individual. Space weather has a huge influence on our air travel and satellite communication, sometimes causing power outages and system failures, and our technology has only given us about 48 minutes’ notice until now. The DKIST will help us predict solar flares 48 hours in advance and understand space weather like we never have before.

Representatives Alexandria Ocasio-Cortez and Andy Levin have introduced a new bill that would build a national infrastructure for electric vehicles.

The EV Freedom Act would allocate the resources for the U.S. to build a nationwide network of electric vehicle chargers within five years, Reuters reports. That would alleviate a major hurdle to widespread electric car adoption, making it far easier for the population to transition away from gas power.

Imagine then, the emancipatory potential of genome editing for these millions.

Realizing this potential, however, will require that genome editing meet with societal approval. The typical response right now when you talk to someone about genetic engineering or reproductive technology is a reference to ‘designer babies,’ eugenics, Nazism, and other evils. These arguments have a very powerful emotional hold over many people, but in my opinion, they simply don’t stand up to scrutiny.

Researchers at the European Molecular Biology Laboratory (EMBL) in Heidelberg and Institut Curie in Paris have shown that the protein SPEN plays a crucial role in the process of X-chromosome inactivation, whereby female mammalian embryos silence gene expression on one of their two X chromosomes.

In their landmark research published in Nature on 5 February, the scientists reveal how SPEN targets and silences active genes on the X chromosome, providing important new insights into the molecular basis of X-inactivation.

In mammals, males and females differ genetically in their sex chromosomes—XX in females and XY in males. This leads to a potential imbalance, as more than a thousand genes on the X chromosome would be expressed in a double dose in females compared to males. To avoid this imbalance, which has been shown to lead to early embryonic lethality, female embryos shut down the expression of genes on one of their two X chromosomes.

Amongst all the different types of cancer treatment, photodynamic therapy — where light in is used to destroy malignant cells — might have one of the strangest side effects: patients are often better able to see in the dark.

Now researchers have figured out why this happens: rhodopsin, a light-sensitive protein in the retinas in our eyes, interacts with a photosensitive compound called chlorin e6, a crucial component of this type of cancer treatment.

The work builds on what scientists already know about the organic compound retinal, which is found in the eye and usually isn’t sensitive to infrared light.

Boeing is considering another test flight for its CST-100 Starliner commercial crew spacecraft amid concerns from a NASA safety panel about its first flight.

Boeing’s Starliner spacecraft launched on Dec. 20, but was unable to dock with the International Space Station as planned because it ended up in the wrong orbit. But of growing concern now are two software problems that were uncovered after the flight was complete.
