Overlooked ribosomal DNA may help explain human size differences

Ribosomal RNA (rRNA), made from many copies of ribosomal DNA (rDNA), is the core component that powers ribosomes—protein-building machines in our body. It helps build proteins by linking amino acids together, and can also fine-tune this process by interacting with other proteins and messenger RNA (mRNA). For a long time, scientists assumed ribosomes were more or less identical within a species. A new study in Cell Genomics is challenging that idea.

Young stars dim quickly in their X-ray output, potentially benefiting orbiting planets

Scientists have found that young stellar cousins of our sun are calming down and dimming more quickly in their X-ray output than previously thought, according to a new study using NASA's Chandra X-ray Observatory. A paper describing the results is published in The Astrophysical Journal. Unlike in the new movie "Project Hail Mary," this quieting of young stars is a benefit for the prospects for life on orbiting planets around these stars, not a threat.

Why England's calorie label rules may help some eating disorders and harm others

Food calorie labels on menus in cafes and restaurants can be helpful for people with binge eating disorders, even aiding their recovery, finds new research from UCL and King's College London. For the study, published in BMJ Public Health, the researchers surveyed 1,001 people aged 16 or over who lived in England and had experienced disordered eating. Since 2022, all restaurants, take-aways and cafes in England with 250 employees or more have had to display the calories of the food and drink they sell on menus, online menus and take-away platforms as part of measures to curb obesity and encourage healthy eating.

Birds that put more energy into parenthood age faster and die younger, research shows

In a new study, appearing in Proceedings of the Royal Society B: Biological Sciences, scientists selectively bred Japanese quails into two groups: laying either relatively large or small eggs. As the quails don't do much "parenting" after eggs hatch, mothers' main contribution is the resources they transfer to their eggs (chicks from larger eggs are more likely to survive).

Illustrator R.W. Alley on how he brings Paddington Bear to life
