UCLA researchers identify a gene as a potential target in treatment-resistant brain cancer glioblastoma multiforme

Researchers at UCLA Jonsson Comprehensive Cancer Center and Semel Institute identified the gene P300 as a potential therapeutic target for treatment-resistant brain cancer glioblastoma multiforme. By blocking P300, tumor cells can be prevented from recovering and growing under the hostile conditions created by radiation therapy.

In medieval Norway, high-class people had stronger bones

A study published in PLOS ONE found that high-status individuals in medieval Norway had higher bone mineral density and were taller than those from lower socio-economic backgrounds. This suggests that socioeconomic status may have played a role in shaping health outcomes over time.

NIH-supported study finds racial disparities in advanced heart failure treatment

A recent NIH-supported study found that Black adults treated at advanced heart failure centers received potentially life-changing therapies, such as transplants and heart pumps, about half as often as white adults due to racial bias. The researchers also suggest that unconscious bias and overt racism may be driving these disparities.

A smoky solution — for plants

Researchers have made a surprising discovery that liquid smoke can enhance plant defense against pests and diseases, leading to new farming practices. The study found that sunflowers grown in soil treated with liquid smoke had larger, thicker, and greener leaves and appeared less prone to pests and disease.

Do caffeine and alcohol affect fertility treatments?

A recent study found no association between women's caffeine consumption and pregnancy or live birth rate after fertility treatments. However, moderate alcohol consumption (84g/week) was associated with decreased pregnancy and live birth rates in both men and women undergoing IVF/ICSI treatment.

Discovery of 119-million-year-old selfish genes in yeast potentially alters our understanding of how parasitic DNA impacts genome evolution

Researchers have discovered a family of selfish genes, wtf, that have survived for over 100 million years in yeast, contradicting established beliefs on their longevity. These 'killer meiotic drivers' transmit themselves to half of offspring and destroy reproductive cells without being suppressed by natural selection.

Method for decoding asteroid interiors could help aim asteroid-deflecting missions

Researchers have developed a method to map an asteroid's interior structure based on its spin changes during close encounters with Earth. This technique, called AIME, could help scientists plan more effective defense strategies for asteroids like Apophis, which poses a significant hazard if it were to make impact.

To be less sedentary, you may need a more active friend

A mathematical model suggests that social interactions between sedentary and moderately active people can stimulate higher levels of overall physical activity in a population. The model found that interacting with moderately active individuals helped sedentary populations become more physically active over time.

Needs and challenges for COVID-19 boosters and other vaccines in the U.S.

The US ranks last in vaccination rates among the world's richest countries, with a mortality rate from COVID-19 30 times higher than influenza. Boosters can reduce the risk of dying and hospitalization by over 90%. All US adults and eligible children should receive booster shots to protect against future variants.
