Higher wealth taxes equal less philanthropy

Higher wealth taxes significantly reduce charitable donations in Norway, according to new research from the University of Texas at Austin. The study finds that allowing larger income tax deductions can increase giving by 4.4%. This suggests a possible solution to soften the impact of wealth taxes on philanthropy.

Rethinking stroke risk in patients with atherosclerotic carotid stenosis

A multicenter study found that radiologically unstable plaque, particularly intraplaque hemorrhage, significantly increases the risk of ischemic stroke and ocular symptoms in patients with symptomatic mild carotid stenosis. Surgical intervention, such as carotid endarterectomy, may be a protective factor for these patients.

Wake-up call for dormant cancer

Researchers at the Weizmann Institute of Science discovered that dormant breast cancer cells accumulate DNA mutations and experience widespread cellular damage, leading to dormancy. Increasing OVOL protein expression can halt cancer cell lifecycle and induce dormancy, but also enables them to reawaken more aggressively.

‘System rife with blame’ could threaten parents’ mental health when their kids struggle with school attendance

Research found parents of children struggling with school attendance experience distress across all aspects of life, rating it as the second most threatening event. Supporting a child with school attendance difficulties imperils parental mental health and causes significant impact on daily mood and anxiety levels.

No more copy-pasting: DNA base editing for better Lactobacillus strains

A Kobe University team developed a DNA base editing technology that enables precise control over microorganism genetic content without using template DNA from other organisms. They successfully applied this technique to industrially important Lactobacillus strains, creating safer probiotics for people with type 2 diabetes.

Mice exhibit altruistic rescue behavior driven by oxytocin

Researchers have found that mice can instinctively exhibit rescue-like behavior toward anesthetized conspecifics without prior training or external rewards. Oxytocin neurons in the paraventricular nucleus are activated when detecting distress signals, releasing OXT and coordinating emotional and motor responses.

Nature positive: lots of rhetoric, little reality

A new study by Griffith University reveals that the term 'nature positive' is being used more for political rhetoric than actual conservation efforts, posing a threat to biodiversity. The research found that only 0.01% of the global tourism sector makes net positive contributions to conservation.

Nature accounting in Colombia makes sound economic case for protecting native ecosystems

The Colombian government is implementing a new agenda including climate- and biodiversity-related programs to compensate landowners for restoring forests or following management practices that maintain nature's benefits. A natural capital account has been developed to quantify natural assets, benefits, and changes over time, providing ...
