Leadership online: Charisma matters most in video communication

A new study by Petra Nieken found that charismatic leadership tactics and consistent video communication lead to better performance in remote work. In contrast, traditional charisma questionnaires did not predict staff performance. The study suggests that managers should convey a consistent impression when using the video channel.

Association Between KRAS/STK11/KEAP1 Mutations and Outcomes in POSEIDON: Durvalumab ± Tremelimumab + Chemotherapy in mNSCLC

The POSEIDON trial found that patients with metastatic non-small cell lung cancer who received a combined therapy of tremelimumab, durvalumab and chemotherapy experienced longer overall survival compared to those who received chemotherapy alone. KRAS/STK11/KEAP1 mutations did not impact the benefit of the triplet regimen.

Future medical applications in drug design

Researchers from the University of Tokyo have identified the Wnt6 morphogen as a crucial regulator of heart development in vertebrates. The study used mathematical modeling and experiments to understand how Wnt6 morphogen distribution is regulated, with potential implications for drug design and tissue repair.

Robotic-assisted lobectomy for early-stage lung cancer provides better patient-reported quality of life compared to video-assisted lobectomy

A study published at the IASLC 2022 World Conference on Lung Cancer found that robotic-assisted lobectomy for early-stage lung cancer yields better patient-reported health-related quality of life measures compared to video-assisted lobectomy. The procedure was also associated with superior lymph node sampling.

Whether it’s medical records, blood or tissue, patients want to know if researchers may use something from them

A new study suggests that members of the public want to know if their health information or samples from their bodies will be used in research or to help develop new biomedical products. The study found that patients are more likely to want notification about research use of their health information than biospecimens.

Potential long-term treatment for asthma found

Researchers at Aston University have developed a new approach to tackle one of the underlying causes of asthma, not just its symptoms. The treatment, which targets the structural changes made by asthmatic airways, shows promising results in mice, reducing symptoms within two weeks and returning airways to near normal.

Do ‘bouncing universes’ have a beginning?

A new study by University at Buffalo physicists Will Kinney and Nina Stein reveals that the latest cyclic model introduces a new problem: the universe must have a beginning. This finding contradicts previous theories, which aimed to address entropy concerns by proposing endless cycles of expansion and contraction.

Poor must not shoulder responsibility for reducing healthcare carbon emissions

Global health researchers argue that poor and vulnerable populations are already bearing the brunt of climate change and will be disproportionately affected by net zero healthcare targets. The NHS in England faces significant challenges in meeting its ambitious emissions reduction goals without exacerbating existing health inequalities.

Rice models moving ‘washers’ that help DNA replicate

Researchers have modelled a key mechanism by which DNA replicates, revealing details about how helicases wrangle DNA during replication. The simulations showed each step of translocation can travel more than 12 nucleotides along the backbone, pinpointing interactions involved in long-distance movement.

BU study: BCG vaccine prevents tuberculosis in young children, but not adults

A recent study suggests that the BCG vaccine is effective in preventing tuberculosis (TB) in children under 5 years old. However, adolescents and adults may require additional protection to maintain immunity beyond childhood. The researchers emphasize the need for booster vaccinations and new TB vaccines to supplement the BCG vaccine.
