Science X / 'Hybrid' immune cells can speed bone fracture healing by unlocking dual repair signals
Scientists from Trinity College Dublin and RCSI University of Medicine and Health Sciences have created new "hybrid" immune cells with the potential to help new bone form after a break by simultaneously promoting blood vessel ...
Medical Xpress / From gut to brain: Scientists engineer bacteria to treat severe liver-related brain dysfunction
When the liver fails, toxins—such as ammonia—that should be filtered from the blood build up and reach the brain. The result is hepatic encephalopathy (HE), a devastating neurological complication of liver disease that can ...
Phys.org / Zinc–redox crosstalk: A new key to cellular protein quality control
Zinc is an essential trace element that controls myriad biological processes. The delicate balance of its concentration in the body is critical; both deficiency and excess are linked to severe pathological states such as ...
Tech Xplore / Molecular interface tweak unlocks more reliable perovskite solar cells, challenging common assumption
Perovskite solar cells are a rapidly advancing photovoltaic technology that has seen a dramatic rise in power conversion efficiency in recent years. A key driver of this progress is the use of molecular charge-selective contacts—ultrathin ...
Phys.org / Invisible fertility crisis: Chemicals and climate change threaten reproduction across species
The rise in infertility is not limited to humans, as environmental stressors are quietly undermining the reproductive potential of different forms of life. A recent review published in npj Emerging Contaminants investigated ...
Science X / Snowball Earth may hide a far stranger climate cycle than anyone expected
During the Sturtian glacial period during the Neoproterozoic Era, Earth underwent periods of global glaciation, which have been described as either "Snowball" and "Slushball" Earth scenarios. In Snowball Earth models, the ...
Tech Xplore / FingerEye bridges touch and vision to improve robot handling before and after contact
To reliably complete various manual tasks, robots should be able to handle a variety of objects, ranging from items found in households to tools used in specific professional settings. While many existing robotic systems ...
Phys.org / An anomaly in global sea level rise is explained by deep ocean heating
Climate scientists like to keep their accounting books neat and balanced. As climate change alters energy flows all across the planet, which in turn causes effects like sea level rise, ice melt and more, keeping close track ...
Phys.org / Organic matter diversity determines how much iron is available for marine life, study finds
How much of the essential trace element iron remains available for marine life in the ocean depends critically on the diversity of organic molecules in seawater, according to new research published in Nature Communications ...
Phys.org / Tiny DNA fragments, big agricultural insights: New genomic approach helps improve crop resilience
The genes that could help the world's crops survive drought, heat, and disease probably already exist. But much of this genetic diversity remains hidden within ancient plant varieties and forgotten seed collections, among ...
Phys.org / Revolving doors weaken SEC oversight, finds research
Regulators often move in and out of revolving doors between government and the industries they oversee. They can bring valuable expertise. But their ties also can raise questions about whose interests their knowledge ultimately ...
Phys.org / A mechanical blue LED: Stretching GaN shifts light from UV to blue without changing chemistry
A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride (GaN) material from ...
