Scientists have published a new, detailed radio image of the Andromeda galaxy—the Milky Way’s sister galaxy—which will allow them to identify and study the regions of Andromeda where new stars are born.

The study—which is the first to create a radio image of Andromeda at the microwave frequency of 6.6 GHz—was led by University of British Columbia physicist Sofia Fatigoni, with colleagues at Sapienza University of Rome and the Italian National Institute of Astrophysics. It was published online in Astronomy and Astrophysics.

“This image will allow us to study the structure of Andromeda and its content in more detail than has ever been possible,” said Fatigoni, a Ph.D. student in the department of physics and astronomy at UBC. “Understanding the nature of physical processes that take place inside Andromeda allows us to understand what happens in our own galaxy more clearly—as if we were looking at ourselves from the outside.”

TSMC 2nm production is likely to begin sometime in 2023, after the company got the green light for its most advanced chipmaking process yet.

The news comes just one day after Intel said it believed it could catch, and overtake, TSMC’s chipmaking capabilities within four years…

A large part of the secret to creating ever more powerful chips is shrinking the die process: getting more transistors into the same size of chip. The A14 chip used in the iPhone 12, designed by Apple and fabricated by TSMC, contains 11.8 billion transistors.

The massive gravity of a black hole actually bent X-ray echoes from around its back.

Researchers have shown that the massive gravity of a black hole actually bent X-ray echoes from around its back, providing more evidence for general relativity.

Psoriasis is a lifelong, autoimmune inflammatory disease. It often appears as a skin condition, but it is a systemic condition that can affect many parts of the body.

Psoriasis often causes skin lesions, but also a higher risk of other conditions, such as celiac, inflammatory bowel disease, and mental health issues. Find out more.

Helion plans to provide the first commercially viable nuclear fusion power! There remain obstacles, but zero-carbon energy is too promising to ignore.

Environmentalists say desalination decimates ocean life, costs too much money and energy. But as Western states face an epic drought, regulators appear ready to approve a desalination plant in Huntington Beach, California.

Scientists have discovered that the protein ubiquitin plays an important role in the regulation of the aging process. Ubiquitin was previously known to control processes such as signal transduction and metabolism. Prof. Dr. David Vilchez and his colleagues at the CECAD Cluster of Excellence for Aging Research at the University of Cologne performed a comprehensive quantitative analysis of ubiquitin signatures during aging in the model organism Caenorhabditis elegans, a nematode worm broadly used for aging research. This method—called ubiquitin proteomics—measures all changes in ubiquitination of proteins in the cell.

The resulting data provide site-specific information and define quantitative changes in ubiquitin changes across all proteins in a cell during aging. A comparison with the total protein content of a cell (proteome) showed which changes have functional consequences in protein turnover and actual protein content during aging. The scientists thus discovered new regulators of lifespan and provide a comprehensive dataset that helps to understand aging and longevity. The article, “Rewiring of the ubiquitinated proteome determines aging in C. elegans,” has now been published in Nature.

“Our study of ubiquitin changes led us to a number of exciting conclusions with important insights for understanding the aging process,” said Dr. Seda Koyuncu, lead author of the study. “We discovered that aging leads to changes in the ubiquitination of thousands of proteins in the cell, whereas longevity measures such as reduced food intake and reduced insulin signaling prevent these changes.” Specifically, the researchers found that aging causes a general loss of ubiquitination. This is caused by the enzymes that remove ubiquitin from proteins become more active during aging. Normally, ubiquitinated proteins are recognized and destroyed by the proteasome, the cell’s garbage truck. The scientists showed that the longevity of organisms is determined by age-related changes in the degradation of structural and regulatory proteins by the proteasome.
