One of the biggest mysteries in science -- dark energy -- doesn't actually exist, according to researchers looking to solve the riddle of how the Universe is expanding. For the past 100 years, physicists have generally assumed that the cosmos is growing equally in all directions. They employed the concept of dark energy as a placeholder to explain unknown physics they couldn't understand, but the contentious theory has always had its problems. Now a team of physicists and astronomers are challenging the status quo, using improved analysis of supernovae light curves to show that the Universe is expanding in a more varied, 'lumpier' way.

We know a lot about how much fossil-derived carbon is emitted to the atmosphere but less about how much is stored in human-made products. Ecological economists estimate that each year, humans add around 400 million tons of fossil carbon to long-lasting products such as plastics, buildings, and human infrastructure. Although these products could be considered a 'carbon sink,' proper waste management is essential to prevent them from becoming environmental hazards.

Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders. A protein called USP53 has been recently linked with progressive familial intrahepatic cholestasis, a hereditary liver disease in children, yet its mechanism of action has remained elusive. While its sequence made it part of a deubiquitinase family, previous attempt to detect catalytic activity had remained inconclusive. Now, a team has decoded the mode of action of USP53 and its related enzyme called USP54.

New studies offer a clearer picture of how the outer solar system formed and evolved based on analyses of trans-Neptunian objects (TNOs) and centaurs. The findings reveal the distribution of ices in the early solar system and how TNOs evolve when they travel inward into the region of the giant planets between Jupiter and Saturn, becoming centaurs. TNOs are small bodies, or 'planetesimals,' orbiting the sun beyond Pluto. They never accreted into planets, and serve as pristine time capsules, preserving crucial evidence of the molecular processes and planetary migrations that shaped the solar system billions of years ago. These solar system objects are like icy asteroids and have orbits comparable to or larger than Neptune's orbit. Prior to the new UCF-led study, TNOs were known to be a diverse population based on their orbital properties and surface colors, but the molecular composition of these objects remained poorly understood. For decades, this lack of detailed knowledge hindered interpretation of their color and dynamical diversity. Now, the new results unlock the long-standing question of the interpretation of color diversity by providing compositional information.

There are several strategies for the early detection of prostate cancer. The first step is often a blood test for prostate-specific antigen (PSA). If PSA levels exceed a certain threshold, the next step typically involves taking a tissue sample for analysis. Another option is to use magnetic resonance imaging (MRI) to search for signs of a tumor before deciding whether a biopsy is necessary, reserving biopsies only for cases where abnormalities are detected. Researchers at conducted a study to determine whether this MRI-first approach is safe over the long term. Their findings show that this strategy poses no additional risk to patients for at least three years.

Hand choice, an unconscious decision, is influenced by target-related information, but if these are non-informative, the choice will be approximately 50-50. In this equilibrium situation, non-target information may also aid in decision-making, but no research has demonstrated this. Now, researchers have investigated the effect of somatosensory stimulation on motor decisions in healthy participants. The results revealed that wrist stimulation significantly increased the likelihood of choosing the stimulated hand, highlighting its application in stroke rehabilitation.

Researchers have discovered a surprising link between a chronic gut infection caused by a common virus and the development of Alzheimer's disease in a subset of people. It is believed most humans are exposed to this virus -- called cytomegalovirus or HCMV -- during the first few decades of life. According to the new research, in some people, the virus may linger in an active state in the gut, where it may travel to the brain via the vagus nerve -- a critical information highway that connects the gut and brain. Once there, the virus can change the immune system and contribute to other changes associated with Alzheimer's disease. This virus may be a target for antiviral treatments.
