Study finds carrying pollen heats up bumble bees, raises new climate change questions

A new study from North Carolina State University reveals that carrying pollen increases the body temperature of bumble bees, potentially putting them at risk due to rising environmental temperatures. The research has significant implications for bumble bee populations and ecosystems, particularly in areas experiencing climate change.

Novel antibiotic succeeds in trial against hospital-acquired pneumonia

The novel combination antibiotic sulbactam-durlobactam has been found to combat dangerous pneumonia at least as well as the best currently approved treatment. The drug has shown significant tolerability and dosing advantages over existing treatments, making it a promising option for combating hospital-acquired infections.

Established cardiovascular disease in people living with overweight or obesity associated with more illness, death and medical costs than obesity alone, UK study in over 420,000 adults finds

A UK study of over 420,000 adults reveals that those with existing cardiovascular disease and overweight or obesity are five times more likely to suffer a stroke and four times more likely to have a heart attack than those with extreme obesity. The study highlights the substantial impact of living with both conditions on individuals, p...

Patients with rheumatic and musculoskeletal conditions vulnerable to long term opioid use

Researchers warn that patients with rheumatic and musculoskeletal conditions are vulnerable to long term opioid use. The study found that up to 1 in 3 patients with rheumatoid arthritis or fibromyalgia may be at risk of transitioning to long term opioid use, highlighting the need for vigilance in practice prescribing.

Emissions reductions of Chinese EVs

A study found that Chinese electric vehicles (EVs) create up to 53% less emissions over their full life cycle than internal combustion engine vehicles by 2030. Increased operating efficiency and a cleaner electricity mix are key drivers of these reductions.

Automated, accurate reporting for NGS-based clonality testing

Researchers have developed an automated calling algorithm for determining B and T cell clonality from NGS data with greater sensitivity than previous models. The new model increases the assay's sensitivity in detecting clonality, allowing for more accurate diagnosis and monitoring of lymphoproliferative disorders.

Brain research with organoids

Scientists have developed a new method to genetically modify brain organoids, allowing for quick and effective analysis of gene function in early stages of brain development. This breakthrough enables comparative studies across primate species and simulates neurological diseases without animal experiments.

Aerobic (“cardio”) exercise linked to significantly lower risk of flu or pneumonia death

Research found that meeting both recommended weekly physical activity targets was associated with a nearly half the risk of dying from flu or pneumonia as those who met neither. Meeting only the aerobic activity target was linked to a 36% lower risk, while muscle strengthening activities showed no significant difference.

New study shows key role of synaptic plasticity in modulating brain function in patients with epilepsy

Researchers used a radiotracer to investigate AMPAR trafficking in patients with epilepsy, finding a positive correlation between cell surface AMPAR density and gamma activity. The study suggests that Hebbian and homeostatic plasticity differentially regulate brain function in epilepsy.

UC Irvine research team identifies glycosylation enzyme critical in brain formation

A UC Irvine research team discovered that the MGAT5 glycosylation enzyme plays a critical role in brain development. The study found that neural stem cells use glycosylation to regulate their reactions to external signals and develop mature brain cells. This discovery may contribute to new therapeutic purposes for neural stem cells.

Combined delivery of engineered virus with immunotherapy is safe and improves outcomes in subset of patients with glioblastoma

A Phase I/II clinical trial combining intratumoral delivery of an engineered oncolytic virus with subsequent immunotherapy improved survival outcomes in a subset of patients with recurrent glioblastoma. The study demonstrated the combination was well-tolerated, with no dose-limiting toxicities.

Most species, including humans, who experience early life adversity suffer as adults. How are gorillas different?

A recent study found that gorillas who survived past age 6 were largely unaffected by difficulties they encountered as infants or juveniles. In contrast, young gorillas who experienced multiple forms of early life adversity had a 70% reduction in the risk of death across adulthood. This suggests that gorillas may have a different biolo...
