What actually happens is much weirder, and may help us understand more about quantum mechanics

Researchers from Osaka University have shown that a protein called HKDC1 is a new target of another protein, TFEB, and plays key roles in maintaining the stability of both mitochondria and lysosomes. HKDC1 is essential for mitophagy to remove damaged mitochondria, and mediates mitochondria–lysosome contact, which is critical for lysosomal repair. The role of HKDC1 in maintaining the stability of these organelles counteracts cellular senescence, revealing HKDC1 as a potential therapeutic target for age-related diseases.

Researchers from Osaka Metropolitan University assessed the correlation between human mobility restrictions and the medical costs associated with lifestyle-related diseases during the COVID-19 pandemic in Japan. A cross-sectional study revealed that an increase in walking and public transit use was associated with reduced medical costs of lifestyle diseases. These findings implicate governments to take measures other than restricting walking and public transit during pandemics and emphasize the importance of walkable cities.

Researchers from Osaka University developed a bio-logger for seabirds that enables long-term observation of rare behaviors. The bio-logger employs low-power depth sensors and accelerometers to identify rare behavior using a light-weight outlier detection model and records the behavior in a 5-min video. Observations using the bio-loggers on Streaked Shearwaters revealed novel aspects of head-shaking and foraging strategies. This approach will enable a wider range of animal behaviors in various environments to be observed.

A research group led by Osaka University and University of Hawaii Manoa found that in female fruit flies, microorganisms enhance reproductive function, boosting the number of cells that form eggs and the number of mature eggs. This is done by controlling the release of hormones to speed up cell division in the ovaries, and limiting programmed cell death. These findings could improve reproductive medicine and could aid the development of new methods to enhance fertility.

Identifying low-cost metal oxide electrocatalysts is essential to help us wean ourselves off fossil fuels. Yet doing so is a time-consuming process, with lots of trial and error required. A group of researchers has explored how data mining can be employed to help speed up this process.

A team of researchers has developed an innovative method to design complicated all-α proteins, characterized by their non-uniformly arranged α-helices as seen in hemoglobin. Employing their novel approach, the team successfully created five unique all-α protein structures, each distinguished by their complicated arrangements of α-helices. This capability holds immense potential in designing functional proteins.

In a phase 2 trial, researchers from Osaka University have found that erythromycin, a commonly used antibiotic, has acceptable safety and tolerability profiles in patients with myotonic dystrophy type 1. This common form of muscular dystrophy currently has no cure, and the research team is hopeful that phase 2b and 3 trials will further reveal the efficacy of erythromycin as a treatment—at least in some patients.

Researchers from Osaka University have discovered how amino acids activate a key cell, TORC1, which is a master regulator in living organisms that controls whether cells grow or recycle their contents in yeast. Notably, the team found that the amino acid cysteine is sensed by a protein called Pib2 and that the two bind together to trigger TORC1. This is important because faulty TORC1 has been linked to disease such as cancer.

Researchers from Osaka University have shown that the rare D-form of the amino acid alanine shows a clear circadian rhythm, and is able to affect the circadian clock and regulate gluconeogenesis, a method of glucose release, in the kidney. D-alanine upregulates genes linked to both gluconeogenesis and the circadian rhythm through the circadian transcriptional network. D-alanine is linked to many metabolic and immunological diseases, and this mechanistic insight could potentially lead to novel therapeutic approaches.
