The secret of short stems

Researchers found that plants with semi-dwarfism in wild Arabidopsis species have a mutated GA20ox1 allele, similar to those in rice and barley varieties bred for high yields. The mutation alters the gibberellin biosynthesis pathway, but other genes compensate for its effects.

Could deceased heart attack victims expand donor pool?

Researchers in the UK found that organs from selected DCD donors with pre-hospital cardiac arrest had no significant impact on graft or transplant recipient survival compared to other deceased donors. The study suggests using these organs could boost the donor pool without adverse outcomes for liver transplant recipients.

Hospitals vary in monitoring and treatment of children with brain injury, reports study in Neurosurgery

A study published in Neurosurgery found significant variations in hospitals' management of children with traumatic brain injury, particularly in ICP monitoring and craniectomy. The study analyzed data from over 7,000 children treated at 156 US hospitals and found that rates of these interventions varied significantly between hospitals.

Teen night owls likely to perform worse academically, emotionally

A new study from the University of California, Berkeley found that teenagers who go to bed late during the school year are more prone to academic and emotional difficulties. The study analyzed data from over 2,700 U.S. adolescents and found that school-year night owls had lower GPA scores and were more vulnerable to emotional problems.

When care is omitted -- new research on a taboo topic

A study by the University of Basel found that four out of thirteen nursing activities are left undone across Europe, with psychoeducational care being the most omitted. The research highlights the negative impact on job satisfaction and suggests optimizing nurse work environments can help reduce this issue.

Of hurricanes, fungus and Parkinson's disease

Researchers found that a volatile organic compound emitted by fungi, 1-octen-3-ol, attacks genes responsible for dopamine transport and packaging, leading to Parkinson's-like symptoms in fruit flies. The study suggests a potential link between fungal exposure and the degeneration of dopamine-producing neurons.

Livermore researchers find tie between global precipitation and global warming

A new study by Lawrence Livermore National Laboratory scientists shows that global precipitation changes are directly affected by human activities and cannot be explained by natural variability alone. The research found that thermodynamic changes and shifts in atmospheric circulation patterns are contributing to the observed changes.
