Improved model of energy highway along protein strands

A new mathematical model describes how polarons can be displaced in a directed way with minimum energy loss in linear peptide chains, accounting for the energy transport mechanism in proteins. The model predicts that a constant electric field can initiate and sustain polaron motion along polypeptide chains.

Differences in aggression among people with dementia

Researchers found that individuals with frontotemporal dementia were physically aggressive earlier and exhibited more severe behavior towards strangers compared to those with Alzheimer's disease. The study of 281 deceased patients revealed a significant difference in the manifestation of aggression between the two groups.

Study shows influence of surgeons on likelihood of removal of healthy breast after breast cancer dia

A study published in JAMA Surgery found that attending surgeons can significantly influence patients' decisions to undergo contralateral prophylactic mastectomy (CPM) after a breast cancer diagnosis. The researchers surveyed over 7,800 women with stages 0-2 breast cancer and their attending surgeons, finding that surgeons' attitudes to...

Wondering if that mole is cancerous? Look at illustrations, not photos

A recent study published in the Journal of Health Communication found that illustrations are more effective than photos in helping people spot problematic moles during skin self-examinations. The research uses eye-tracking technology to show that participants fixate on atypical moles longer with illustrated visuals, leading to increase...

New supernova analysis reframes dark energy debate

A new study finds a model universe with no dark energy provides a slightly better fit to Type Ia supernovae data than the standard dark energy model. The 'timescape cosmology' challenges current understanding of the Universe's expansion, highlighting the need for more data and better supernova precision.

Asthma drug from the garden center

Researchers at the University of Bonn have developed a new compound extracted from coralberry leaves that effectively relieves bronchial spasms and may be more effective than common asthma medication salbutamol. The study was conducted in mice, but further human trials are needed before its application.
