New study unveils epigenetic ‘traffic lights’ controlling stop and go for gene activity

A major new study in the journal Nature reveals a 'traffic light' mechanism controlling genetic activity within cells. The research describes how epigenetic changes act as a stop-go signal determining whether a gene should be read, and how this system could potentially be targeted by cancer drugs already in development.

Ice-cold electron beams for ultra-compact X-ray lasers

Researchers at the University of Strathclyde have simulated ice-cold electron beams that can produce powerful coherent photon pulses with pulse durations in the attosecond regime. The breakthrough could lead to the development of ultra-compact X-ray lasers, reducing their size from kilometres to just tens of metres.

Vitamin B5 could help improve red blood cell production in people with Myelodysplastic syndromes

Researchers have discovered that the enzyme COASY plays a critical role in regulating red blood cell production in the bone marrow. Vitamin B5 supplementation and another metabolite increased the maturation of red blood cells in patients with Myelodysplastic syndromes, offering new hope for alternative treatments.

What distinguishes fans from celebrity stalkers?

A survey study of U.S. college students found that individuals who frequently think about their favorite celebrities, feel compelled to learn more about them, and are prone to boredom are more likely to engage in celebrity stalking behaviors. These factors were not associated with anger or thrill seeking.

National Comprehensive Cancer Network updates annual conference with new in-person venue, hybrid format, expert-led sessions, highlighted research perspectives, and small-group conversations

The NCCN Annual Conference will debut a new hybrid format featuring in-person events at a new venue, allowing for hallway conversations and networking opportunities. The conference will also showcase more than 100 abstract poster presentations on various oncology-related categories.

UCO studies yield a better understanding of how cyanobacteria take advantage of glucose

Researchers at the University of Córdoba have shed light on how marine cyanobacteria, the most abundant photosynthetic organisms on Earth, take advantage of glucose as a source of energy. They found that glucose transport is greater during the day and follows a different circadian cycle than other bacteria in the same area.

America on the move: How urban travel has changed over a decade

A Florida Atlantic University study reveals that while private automobiles remain dominant, the share of car trips has decreased since its peak in 2001. In contrast, transit, non-motorized, and taxicab trips have increased. Lower-income groups rely heavily on public transportation due to limited mobility options.

Ice Age survivors

The study of 356 prehistoric hunter-gatherers from across Eurasia sheds light on the movements and genetic replacements of ancient populations. Genetic analysis reveals that populations in western Europe took shelter during the Last Glacial Maximum, while those in central and southern Europe died out or replaced with new gene pools.

Scientists discover how to prevent death of nerve cells in most common forms of MND and dementia

Researchers at the University of Sheffield's Institute of Translational Neuroscience have discovered a novel way to block the transportation of mutant RNA and toxic repeat proteins that lead to the death of nerve cells in most common forms of motor neurone disease (MND) and frontotemporal dementia (FTD). Using a peptide, they found tha...
