Medical Xpress / Unusual tumor cells may be overlooked factors in advanced breast cancer
An enigmatic type of circulating tumor cell called a dual-positive (DP) cell is associated with shorter survival time in patients with advanced breast cancer, according to a study led by investigators at Weill Cornell Medicine ...
Phys.org / Titanium complexes cleanly edit the core skeleton of highly stable organic compounds
Multi-titanium hydrides can selectively snip the strong structural bonds of stable organic molecules called pyridines, RIKEN researchers have shown. This discovery could guide designing catalysts for applications in multiple ...
Phys.org / Despite their contrasting reputations, bonobos and chimpanzees show similar levels of aggression in zoos
Chimpanzees have a reputation for being aggressive, while bonobos are often seen as their peaceful counterparts. This contrast has frequently been used to explain different sides of human nature. However, a new study by Utrecht ...
Tech Xplore / Low-cost, high-performance plastic heat exchanger rivals traditional metal systems
A recent study in Advanced Science reports an innovative, low-cost polymer heat exchanger that could transform how industries manage heat. The device was developed by a Rice University research team led by Daniel J. Preston, ...
Phys.org / Galaxy-group motion suggests slower expansion in our cosmic neighborhood
Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that analyzes the motion of two nearby galaxy groups within their surrounding cosmic flow. The results ...
Phys.org / Astronomers collect rare evidence of two planets colliding
Anastasios (Andy) Tzanidakis was combing through old telescope data from 2020 when he found an otherwise boring star acting very strangely. The star, named Gaia20ehk, was about 11,000 light-years from Earth near the constellation ...
Phys.org / Fish study shows that sexual harassment behavior might matter for ecosystems
For decades, ecologists have known that how a species looks or eats affects its environment. But a new study by researchers at the University of California, Santa Cruz, shows that social behavior related to mating can be ...
Phys.org / Compact vacuum ultraviolet laser may improve nanotechnology and power nuclear clocks
Physicists at the University of Colorado Boulder have demonstrated a new kind of vacuum ultraviolet laser that is 100 to 1,000 times more efficient than existing technologies of its kind. The researchers say the device could ...
Medical Xpress / Why street layouts may matter for aging brains: Brain scans link walkability to memory
The simple act of crossing a road could help shield the brain from dementia and other cognitive conditions, according to new research from the Australian Catholic University and UNSW Sydney's Center for Healthy Brain Aging ...
Medical Xpress / Severe COVID-19 and flu can facilitate lung cancer months or years later
Severe COVID-19 and influenza infections prime the lungs for cancer and can accelerate the disease's development, but vaccination heads off those harmful effects, new research from UVA Health's Beirne B. Carter Center for ...
Medical Xpress / Foreign aid cuts to tuberculosis services could cost families $80 billion worldwide
More than a year after the second Trump administration began dismantling the US Agency for International Development (USAID), the global health consequences of this unprecedented loss in international aid continue to surface. ...
Phys.org / Stacked quantum materials enable precise spin control without external magnetic fields
Spintronics—a technology that harnesses the electron's magnetic quantum states to carry information—could pave the way for a new generation of ultra-energy-efficient electronics. Yet a major challenge has been the ability ...
