Read: Unusual Cell Division in Common Mouth Bacteria Reshapes Our Understanding of Dental Plaque

The galaxy cluster MACS-J0417.5-1154 is so massive that it bends the fabric of space-time. This causes the appearance of galaxies behind it to be distorted, an effect known as gravitational lensing. This natural phenomenon magnifies distant galaxies and can also make them appear in an image multiple times, as NASA's James Webb Space Telescope has observed. In this image, two distant, interacting galaxies - a face-on spiral and a dusty red galaxy seen from the side - appear multiple times, tracing a familiar shape across the sky. The fact that these galaxies are actively forming stars and that the face-on galaxy's spiral shape is remarkably intact indicates that their interaction is just beginning.

Recent research led by Washington State University (WSU) offers hope for at-risk butterflies, revealing that their populations fared better when their habitats were actively managed. The study examined 31 at-risk butterfly species across the U.S., all of which are experiencing rapid declines due to habitat loss, climate change, and pesticide use.

The image displays four views of a person's brain, highlighting the boundaries between different functional brain networks, each represented by different colored lines, as mapped using functional MRI. This map is overlaid on a salience network connectivity heat map, where warmer colors indicate stronger connectivity within the salience network. Researchers discovered that a larger salience network may be associated with an increased risk of depression. Credit: Lynch/Liston Labs.

Researchers at WashU Medicine have developed a method in mice to reduce damage from spinal cord injuries by using engineered immune cells. Mice that received this treatment showed improved recovery from their injuries, indicating potential for developing this therapy for human use.

A powerful laser is directed into a jet of gas, forming a bright plasma that generates ultraviolet light. As this light interacts with the remaining gas in the vacuum chamber, it creates a visible white line. This method allows scientists to accurately measure the energy required to excite the thorium-229 nucleus, which is crucial for developing a future nuclear clock.

Researchers investigated the function of PQBP3, a protein that was previously linked to certain neurodegenerative diseases, and unveiled its role in maintaining the integrity of the nuclear membrane. In senescent (aged) cells, PQBP3 concentration is decreased thereby promoting Lamin B1 degradation, and PQBP3 leaks from its typical place in the nucleolus to the cytosol, which in turn causes the nuclear membrane to get destabilized.

Protein Discovery Illuminates Link Between Aging and Brain Diseases

Kobe University researcher Naoyuki Hirata was the first to discover that an asteroid impact on Jupiter's moon Ganymede occurred almost exactly on the meridian farthest from Jupiter. This finding suggested that Ganymede had experienced a reorientation of its rotational axis, enabling Hirata to calculate the type of impact that could have caused this shift.
