	FDA clears heart tissue regeneration drug AD-NP1 for clinical trials The body's tissues can get injured in many ways, but while some injuries heal perfectly, others don't heal at all. A cut in the skin, for example, usually heals all on its own, while internal organs, such as the heart after a heart attack or the kidney after an acute injury, remain damaged, leading to diminished function. Most tissues of the body repair themselves using the same processes, but until now, drugs that target these pathways to enhance tissue repair in slow-healing organs have not been identified. That's about to change.

	Rare disease possibly identified in 12th century child's skeletal remains In the journal Childhood in the Past, Ph.D. candidate Duru Yağmur Başaran published the results of an analysis of an over 900-year-old skeleton of a child. The study revealed that a 2.5 to 3.5-year-old child had suffered from a rare disease seldom seen in archaeology.
	By removing common biases, study debunks U-shaped happiness curve with age Many survey-based studies have been conducted to try to understand how happiness changes over a person's lifetime. While there have been a few different outcomes, the most common has been the U-shaped curve. This pattern indicates that, on average, people are happier at the beginning of adulthood, they experience a dip during midlife (the so-called "midlife crisis"), and happiness then increases again in old age. Yet, other similar studies have reported inconsistent patterns—steady happiness throughout life, steady increases, steady decreases or even inverse U-shapes.
	'Battleship'-style math can improve sustainable design, groundwater management, nuclear waste storage and more In an approach reminiscent of the classic board game "Battleship," Stanford researchers have discovered a way to characterize the microscopic structure of everyday materials such as sand and concrete with high precision.
	When mathematics meets aesthetics: Tessellations as a precise tool for solving complex problems In a recent study, mathematicians from Freie Universität Berlin have demonstrated that planar tiling, or tessellation, is much more than a way to create a pretty pattern. Consisting of a surface covered by one or more geometric shapes with no gaps and no overlaps, tessellations can also be used as a precise tool for solving complex mathematical problems.
	Development of new grouting material offers solution to ancient grotto erosion Inspired by ancient Roman concrete techniques, a team led by Prof. Ma Xiao from the University of Science and Technology of China (USTC) developed a novel low-cost, highly durable calcium-silicate-hydrate-based grouting material for grotto conservation. Their research is published in Advanced Science.
	Screen time linked to lower academic achievement among elementary students in Ontario, Canada Higher levels of screen time in early childhood are associated with lower scores in reading and mathematics on Ontario's standardized tests, with each additional hour of daily screen time associated with a 10% drop in the likelihood of achieving higher academic levels. Published in JAMA Network Open, the findings are part of a new study from TARGet Kids!, a collaborative research network co-led by Dr. Catherine Birken at The Hospital for Sick Children (SickKids) and Dr. Jonathon Maguire at Unity Health Toronto's St. Michael's Hospital.
	Pointless work tasks driving employees to switch off and burn out, new research finds Unfair or pointless work tasks are driving more employees to mentally check out, turning to the internet to cope with stress, sleepless nights, and next-day burnout, new research shows.
	Caregivers identify key barriers to youth enrichment programs in low-income communities Primary caregivers of children and adolescents say that broad outreach, easy enrollment, and low financial barriers are among key ways to improve access to out-of-school-time (enrichment and recreational) activities in urban, under-resourced communities, new research finds.
	The evolution of male mental health in television Shows about men still dominate our television screens. But the stories being told are starting to change, with more room for vulnerability and portrayals of male mental illness. These changes include explicit mentions of diagnostic categories and male characters with mental illnesses in the lead role.
	Access to official information and trust in government boost expatriate voting among undocumented immigrants The global increase in migration—with approximately 3.6% of the global population living as expatriates—has resulted in many countries extending external voting rights to their overseas citizens. This has prompted scholarly interest in understanding the electoral participation of immigrants in their countries of origin.
	First-of-its-kind report reveals rise of athlete-owned media Athlete-owned media is more than a trend; it's an economic and cultural shift. By creating content and owning their own platforms, athletes are deciding which stories get told, expanding representation and bringing fans closer than ever. "Owning the Narrative," a first-of-its-kind report from USC Annenberg's Norman Lear Center, maps how this rapidly growing industry is redefining sports media and influence.
	'Nothing to see here': How corporate spin confuses Wall Street Public-relations professionals call it "getting ahead of the story"—feeding positive spin to the media to blunt the impact of unflattering news to come. Celebrities engage in it; so do companies when, for example, their forthcoming earnings report is destined to disappoint. But do these face-saving distraction tactics affect the long-term movement of share prices?
	New model helps supermarkets keep shelves stocked during crises—and go greener Supermarket shoppers across the U.K. are all too familiar with empty shelves when disruption strikes. Whether it was the panic buying of COVID-19, floods affecting deliveries or strikes in distribution centers, the fragility of supply chains has affected most of us in recent years.
