Medical Xpress / Supercentenarians have an abundance of cancer-killing immune cells
The human immune system has specialized cells called CD4 cytotoxic T lymphocytes (CD4 CTLs), which have been shown to kill tumor cells in some cancers. When a person gets sick, these cells multiply in a process called clonal ...
Phys.org / Natural forest regrowth offers a lower-cost path to climate and biodiversity goals
As nations race to restore ecosystems and curb climate change, research has shown that letting nature do the work is a cost-effective, viable solution. A study from the University of Queensland and the University of Newcastle ...
Phys.org / Reframing Homer's Sirens through gender, nature and social order
Though they are pivotal to Homer's epic, luring Odysseus with the promise of eternal wisdom, the Greek poet barely described the mysterious Sirens. What might a better understanding of these formless, disembodied feminine ...
Phys.org / How we found Haida Gwaii's first marbled murrelet nest in more than 30 years
Scrambling through dense salal in the dark, weaving between the majestic western red cedars of northern Haida Gwaii, I could barely imagine where we were just days before—crossing Dixon Entrance off the coast in an open skiff, ...
Phys.org / Ocean plankton reveal sugar-for-nutrients partnership that sustains life in barren seas
In the vast, nutrient-poor regions of the world's oceans, there is a constant struggle for survival. Yet tiny organisms known as Collodaria have thrived there for millions of years. These Collodaria host microscopically small ...
Medical Xpress / Lung cancer patient becomes tumor-free after treatment with sodium selenite
A patient with advanced, treatment-resistant lung cancer became tumor-free after treatment with the selenium compound selenite. This is shown in a new study from Karolinska University Hospital and Karolinska Institutet published ...
Medical Xpress / Gut bacteria may transform spinach, beets and plant iron into protective compounds
Researchers at Karolinska Institutet have discovered that gut bacteria can convert dietary nitrate and iron into protective molecules that may reduce the risk of cardiovascular and metabolic diseases. The study, published ...
Phys.org / Gold nanoclusters could help break down Alzheimer's amyloid plaques
Alzheimer's disease is a neurodegenerative brain disorder characterized by progressive memory loss and a decline in other mental functions. Past studies have consistently linked this disorder to the accumulation of the protein ...
Medical Xpress / Robotic assisted knee replacement gives same patient outcomes as surgeon-only procedure in clinical trial
Robotic assistance is increasingly used in knee replacement surgery worldwide: in 6% of procedures in the UK, compared with 16% in the U.S. and 42% in Australia. The aim is to help surgeons place knee replacements more precisely ...
Phys.org / Rising ocean temperatures reduce the natural carbon storage capacity of seagrass meadows
A new study published in Communications Earth & Environment, with contributions from researchers at the Leibniz Centre for Tropical Marine Research (ZMT), shows that higher seawater temperatures could significantly reduce ...
Tech Xplore / Holographic laser printing makes 3D shapes—voids and all—in one shot
Researchers at the University of Utah's John and Marcia Price College of Engineering, in collaboration with researchers from The University of Texas at Austin, have demonstrated a new method of 3D printing that avoids the ...
Phys.org / Rethinking how we name and classify our human ancestors following recent evolutionary discoveries
Recent advances in our understanding of human evolution challenge the way we currently name and classify our ancestors, according to new research from Monash University. The study, published in the American Journal of Biological ...
