RNA emerges from DNA's shadow

Recent RNA research reveals new roles in regulating gene expression and structural components, with potential for creating compounds to overcome genetic disorders. The EUROCORES programme brings together European groups to collaborate on RNA quality control and its applications.

Purified stem cells restore muscle in mice with muscular dystrophy

Researchers have shown that purified stem cells isolated from adult skeletal muscle can restore healthy muscle and improve muscle function in mice with muscular dystrophy. The injected cells also replenished the pool of regenerative cells normally found in muscle, allowing the treated muscle to undergo subsequent rounds of injury repair.

Projected California warming promises cycle of more heat waves, energy use for next century

Projected California warming promises a cycle of more heat waves and increased electricity demand for the state, raising the risk of power shortages during extreme heat events. The study predicts that widespread climate warming could strain the electricity grid, making brownouts or rolling blackouts more frequent.

Researchers hack final part of the immune system code

A team of researchers from the University of Copenhagen has deciphered the final part of the immune system's key codes using artificial neural networks. This breakthrough should enable the prediction of all known and unknown immune system codes, leading to new targeted treatments for cancer and infectious diseases.

UGA researchers discover mechanism that explains how cancer enzyme winds up on ends of chromosomes

Researchers at UGA's Franklin College of Arts and Sciences have identified a mechanism that explains how telomerase enzymes are recruited to chromosome ends in cancer cells. The study highlights the potential for targeting telomerase as a means to stop cancers from spreading, providing new avenues for investigation into cancer growth.

Rutgers research identifies brain cells related to fear

Researchers at Rutgers University have identified a key component of the amygdala's neural network involved in extinction, or elimination, of fear memories. Clusters of intercalated neurons inhibit amygdala outputs to brain stem structures generating fear responses, offering potential for pharmacological interventions.

Study: Scientists leave the ivory tower

A study by Helmholtz Association researchers found that over half of scientists had predominantly good contact with journalists, while four out of ten reported beneficial media coverage for their career. The study dispels the idea that German researchers struggle to communicate with the media.

Survey: Most effective dental braces are least attractive

A survey of adults found that less metal is better when it comes to the attractiveness of orthodontic braces. Clear trays and teeth with no visible appliances were considered the most attractive options. However, these more aesthetically pleasing options often come with limitations in terms of movement and force delivery.

The Internet, alcohol and sleep

A new study found that more Internet time, less sleep, and higher alcohol consumption are associated with weight gain in adolescent girls. Girls who consumed 2 or more alcoholic beverages a week or slept less than 6 hours a night gained more weight.

Research highlights problems of predicting birthweights in obese mothers

The study found that the gestation-adjusted projection method (GAP) produced impressive results, accurately predicting birth weights in over 90% of cases. The GAP method uses ultrasound measurements and a mathematical formula to determine whether the baby is larger than average size for its gestational age.

Gender, time of day affect response to vaccination

Researchers found that men vaccinated in the morning showed strongest immune response to both hepatitis and influenza vaccines. The study's results have implications for vaccination timing, suggesting that adults could be vaccinated at specific times of day to increase their protection against flu.
