DNA template could explain evolutionary shifts

Scientists identify a DNA template switching mechanism that can result in rearrangements of genes and exons, leading to copy number variation. This process, called fork stalling and template switching, occurs during cell division and can cause significant changes to the genome.

Big disparities in the treatment of arrhythmias across Europe

The European Heart Rhythm Association's (EHRA) White Book reveals significant disparities in arrhythmia treatment across Europe. The book highlights differences in guideline implementation, trained physicians, and implantation rates, with some countries having no reimbursement for ICD or pacemaker therapy.

Dino-not-so-soaring

Scientists re-examined data to discover a flawed statistical model used for calculating dinosaur mass, leading to revised estimates of Apatosaurus louisae at 18 tonnes instead of 38 tonnes. This finding has significant implications for various theories about dinosaur biology.

Implanted defibrillators: New recommendations for drivers with ICDs

Patients with Implantable Cardioverter Defibrillators (ICDs) are at risk of sudden incapacitation while driving. A new consensus statement recommends driving restrictions based on the type of ICD and individual patient risk. The guidelines aim to balance patients' independence with safety concerns.

Fate in fly sensory organ precursor cells could explain human immune disorder

Notch signaling plays a crucial role in determining cell fate in fruit flies. A study found that mutations in the WASp gene affect T-cell function, leading to Wiskott-Aldrich syndrome. The researchers suggest that defects in Delta presentation could explain the loss and dysfunction of T-cells in patients with the disorder.
