Phys.org / A new, useful absorption limit for ultra-thin films
Ultrathin, conductive films such as those made of graphene are widely used in modern optoelectronic devices, but it has been thought that their efficacy is fundamentally limited: they can absorb at most half of the incident ...
Phys.org / Physicists discover long-predicted 'clock magnetism' in an atomically thin crystal
Strange things happen to materials when you peel them down, layer by layer, from thick chunks all the way to sheets just an atom thick. Reporting in the journal Nature Materials, a team led by physicists at The University ...
Medical Xpress / Fecal transplants from older mice found to significantly improve ovarian function and fertility in younger mice
A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome (the collection of all ...
Phys.org / Feral horses and cattle create more resilient nature, rewilding study reveals
Protected natural areas across Europe are changing. Climate change, with rising temperatures and heavy rainfall, is turbocharging the growth of shrubs and trees, choking the flowers and insects that need the light and heat ...
Phys.org / First 3D reconstruction of the face of 'Little Foot' completed
Identified as the most complete Australopithecus fossil discovered to date, "Little Foot" was buried in sediments whose movement and weight caused fractures and deformations, making analysis of its skull—and more particularly ...
Medical Xpress / Painless skin patch offers new way to monitor immune health
Researchers at The Jackson Laboratory (JAX), in collaboration with the Massachusetts Institute of Technology (MIT), have developed the first bandage-like microneedle patch that can sample the body's immune responses painlessly ...
Phys.org / Large land predators were hunting big plant-eaters more than 280 million years ago, study finds
A study examining fossil evidence shows that large land predators were already hunting big plant-eating animals more than 280 million years ago. University of Toronto Mississauga researchers Jordan M. Young, Tea Maho, and ...
Medical Xpress / Tiled amplicon sequencing could transform tuberculosis care
When the COVID-19 pandemic was at its peak, and multiple variants were threatening lives around the world, scientists relied on a process called "tiled amplicon sequencing" to track the virus's spread. Now, an international ...
Medical Xpress / COVID lockdowns set back children's development by years, study reveals
The COVID pandemic disrupted children's ability to self-regulate, according to new research from the University of East Anglia. A new study reveals that the pandemic hampered children's ability to regulate their behavior, ...
Phys.org / 3D-printed 'plug' links fiber optics to photonic chips with low loss
Physicists and chemists at Heidelberg University have realized a photonic microchip that is driven by light just as easily as electronic components via a "plug." Their development could serve as the basis for fast and cost-effective ...
Phys.org / What happens if truth is lost? Philosopher explains how truth defines our humanity
Behind every breakthrough, there is a quest for truth. This desire is wired into humans—an insatiable curiosity about the world. Questions about truth have perplexed philosophers for thousands of years, but many focus on ...
Phys.org / Dissolvable hydrogel could enable personalized bone implants
Bones broken in a skiing accident usually heal on their own. But if the break is too severe or a bone tumor needs to be removed, surgeons insert an implant that enables the bone to grow back together. Implants often consist ...
